Suggested March 2024 How Educators Can Use Plcs For Innovation And Support
A new wave of online learning communities helps address the challenges of revised priorities, distracting social media, and out-of-reach education conferences. They can give new and experienced teachers a way to connect to high-quality resources and educator colleagues around the world.
Professional learning communities (PLCs) are groups of educators that share resources and expertise, and they may work collaboratively to support the work, growth, and spirit of educators. Traditionally, PLCs are localized in your school or district. But increasingly, learning communities leverage tech to include educators around the globe. These connections can be formal, such as a paid membership to a professional organization; informal connections, such as people you meet at a conference or follow on social media; or something in between.
Why Teachers Need a PLC
While the reasons for expanding your PLC might vary depending on where you are in your career, they all center on key principles about self-directed personal and professional growth.
Innovation and support: We all get stuck in a rut sometimes or just haven’t quite figured out how to get past pedagogical challenges. PLCs can provide fresh lesson ideas and give you strategies for implementing new curriculum. They can be that source of inspiration and lift you up when times are tough.
The connections I’ve made with educators around the world have helped me see my work from new angles and inspire me with their creative solutions and novel approaches to teaching.
Look outside your area of expertise
There’s much to gain from leaning on content-area experts—they know your curriculum, face similar challenges, and can help you resolve current problems. However, in my experience, it’s been helpful to create an interdisciplinary PLC with educators in math, science, arts, language, and social studies.
It’s important to keep in mind that there’s always overlap in project-based learning, student-centered classrooms, assessment, tech integration, and finding new ways to engage students and parents. So why wouldn’t we rely on a larger hive mind of talent to help us improve our teaching? Breaking down subject-area silos also helps make connections to other content areas in our own lessons, and by doing so it helps students see their learning in a wider context.
What to look for in a PLC
1. High-quality resources. It can take a while to find a PLC that meets your needs, especially online, where the quality of resources can vary widely. When looking for teaching resources, it’s helpful if they are vetted by trusted experts. Many formal PLCs either have done this themselves through editors and teams of content-area experts or rely on educational leaders like teachers or administrators with a track record of sharing high-quality resources. PLCs developed by tech companies may privilege their own apps and services, but they often share high-quality teaching and learning resources that are device agnostic, usually for free.
2. Training and certification. Many formal PLCs often provide certifications, badging, and other forms of recognition. Getting recognized by a regional, national, or international organization not only helps your professional growth but also tells administrators, parents, and your students that your professional learning is meaningful, rigorous, and backed by a respected organization. Many of these trainings and certifications can count toward your professional growth hours.
HELPFUL PLCs for educators
Adobe Education is centered on creativity and innovation and provides resources and certifications to teachers for free. Most lessons and resources focus on Adobe apps such as Creative Cloud and Express (formerly Spark), but many are universal in nature, such as goal setting, and are subject-specific resources for social studies, math, and humanities. Join the Adobe Education PLC, Adobe Creative Educator, to join conversations, access training, and earn certifications.
Look for helpful content created by Apple Professional Learning in topics like edtech, creativity, leadership, and coaching. An Apple ID (free) is needed to sign in to the Community and post to the Forum, but anyone can view the content.
One of the most trusted brands, National Geographic Education, has a treasure trove of content, including lessons, free courses for teachers, certifications, grants, and more. Their content isn’t just for science and social studies—it extends across all subject areas, including arts and language arts. Some of my favorite resources are their online courses for teachers: “Teaching Geo Inquiry” and “Storytelling for Impact.”

These days, physical SIM cards come in various forms designed to fit phones of all sizes. When you want to change networks, it’s as simple as taking the old SIM out and putting in a new one – that is, if your phone is unlocked! However, this is not the only way users can change networks, as eSIMs are beginning to gain traction. If you have been wondering what an eSIM is, you have landed in the right place. Here we will try to answer all queries you might have about eSIMs.What Is an eSIM?
An eSIM or embedded SIM is just as its name suggests – a SIM card embedded within the device itself. An eSIM is basically an electronic and programmable form of a traditional SIM card on which you need to download a SIM profile from your carrier. It can also be called a virtual SIM as you can connect to your carrier network without a physical SIM card.
At the same time, you won’t find a eSIM card port on the phone, and you can’t physically take it out of the device. It’s buried within the phone’s processor and not removable. However, just like a swappable SIM card, you can change the eSIM to a different network (if it’s not locked that is). eSIMs are rewritable. That means you can change networks without removing your SIM. However, you will have to erase the existing eSIM profile and activate the new one.
eSIMs provide alternatives for phones that do not support a second SIM card. Most big manufacturers like Apple, Google, Samsung, etc., have incorporated eSIMs in some way or the other.eSIM vs Physical SIM: What’s the Difference
While both eSIM and physical SIM provide the same functionality, they differ in a number of ways:
The physical SIM is removable. That’s not the case with eSIM as you cannot physically remove it.
One can easily switch phones in case of physical SIM cards. In contrast, you will need to contact your mobile carrier in most cases to change eSIM from one device to another.
SMS services might stop working for 24 hours as you transfer your eSIM to a new device. Nevertheless, this is a security measure that may not be applicable to all mobile carriers. Case in point, in our experience they did stop working while using the JIO network in India. You might be able to avoid this inconvenience by reading the instructions very carefully before switching your eSIM to a new device. Comparatively, this doesn’t happen when you switch a physical SIM card to a new device.
Traditional SIM cards can store contacts. This is not possible with eSIMs. But it shouldn’t matter much as most users store contacts in the cloud now.Who Can Use eSIM?
At this point in time, eSIM isn’t available just to everyone. You’ll need to have a certain phone model and use a certain network to be able to give it a try. Today, it’s mostly flagships that offer eSIM capability including:

iPhone XS / XS Max or newer
iPhone SE (3rd Gen)
Google Pixel 3+
Samsung Galaxy S20 series +
In addition to mobile phones, smartwatches like Apple Watch Series 3 and above, Samsung Galaxy watches, and many computers also include eSIM technology. Apart from that, other IoT products like cars, smart meters, security systems, etc., can also support eSIM.
In the US, AT&T, T-Mobile USA, Verizon Wireless, Truphone, Ubigi, and Visible support eSIM.
A carrier’s both new and existing users can apply for eSIM. For existing users, their physical SIM card will become non-functional after activating eSIM.How to Activate eSIM
The steps to activate eSIM differ slightly for each mobile operator and device. However, in most cases, the mobile operator will share a QR code consisting of the eSIM profile that you need to scan from your mobile.
Or, you will have to manually activate the profile by sharing your phone’s IMEI and IMSI numbers. Don’t worry. Your mobile operator will share a complete set of instructions when you apply for eSIM. Below you can see an example of a SMS sent by our mobile operator which includes the complete instructions on how to activate our eSIM.Advantages of eSIM Cards
Moreover, eSIM cannot be damaged or lost unlike your physical SIM card unless you lose your phone. Also, eSIM is secure as it can’t be duplicated easily, provided you don’t share the QR code or other important information like IMSI or virtual SIM number with others.
Also, by removing the tray required for SIM cards, manufacturers can design their phones to be thinner. You don’t have to worry about the SIM change – just enjoy your sleeker device!
Further, in order to use eSIM, both the network provider and your smartphone should have support for the eSIM functionality otherwise it won’t work.
eSIM also makes it difficult to identify and fix network issues. Generally, one would remove the physical SIM card or put it in another phone to check if the problem is due to the network or on the phone. This isn’t easy to handle with eSIMs.
The move from a user-replaceable SIM to one fixed inside the device is causing some users to voice concerns about limitations, identifying this aspect as another part of the phone they can’t customize.Frequently Asked Questions Can you convert from eSIM to physical SIM?
Yes, you can switch to a physical SIM card from an eSIM. However, you will need to contact and visit the mobile carrier store in order to do so.How many eSIM profiles can you store on one device?
Some devices can only store one profile, so you’ll need to erase the old and download the new network profile to make the change. Other devices allow you to store multiple eSIM profiles. You can easily switch to one of them from the device’s settings on the fly.Is it possible to receiving calls from both SIM cards on the same phone?
You can make and receive calls from both numbers on your phone. However, you can receive or make calls from only one number at a time. That is, if you are on a call from one number, you won’t receive calls to another number. Call waiting functionality only works for the calls for the same SIM card.

So what’s the best VPN for torrenting your favorite flavor of Linux and maybe a little Open Office? Here are our top picks.
Updated 01/11/2023: Check out our review of the latest version of Windscribe VPN. The latest version builds upon its already strong feature set with increased speeds, a more robust browser extension, and of course their already impressive free version.
1. ProtonVPN – The best choice hands down
Easy-to-use multi-hop feature
Supports TOR over VPN connections
Best Prices Today:
ProtonVPN has some of the fastest speeds around, both upstream (1st place) and down (2nd place), which is helpful when you want to spread the Open Office love as quickly as possible. It also has excellent privacy promises, and it has a bunch of servers in a friggin’ bunker, which is pretty cool. ProtonVPN has an excellent interface, it’s ownership is well known, it’s based in Switzerland, and did we mention the speeds are solid?

2. OVPN – Best for diskless servers
Privacy and anonymity are top priorities
Accepts cash payments for added anonymity
Smaller number of servers
Limited country selection
While it’s not as well known as other services, OVPN is one of the, if not the, earliest pioneers to deploy diskless servers across its network, keeping everything in RAM. (That has since become common among VPN providers.) OVPN is based in Sweden, it makes the right privacy promises, and while it’s not in our top 10 for speeds, OVPN’s speeds were very good on the whole. It just had a few weak spots, but if you stick to European servers (or North American ones for non-torrent uses) the speeds should be outstanding.

3. Mullvad – Best for anonymity
Higher level of anonymity possible than with most VPN services
Windows desktop is easy to use
Not guaranteed to work with Netflix
Lacks the extra services that some VPNs offer
No password protection for your account
Best Prices Today:
Mullvad is the ultimate VPN when it comes to privacy and anonymity. The Sweden-based company appreciates your business, but it’s not interested in finding out who you are. Instead of using an email and password combo, Mullvad randomly generates an account number that functions as your username and password. Mullvad is in the top 10 for speeds, and of course its privacy promises are top notch.

4. ExpressVPN – Best all-purpose option
Consistently good speeds
Easy-to-use desktop program
Broad device support
Logs data transfer amounts
More expensive than many competitors
ExpressVPN is our favorite VPN so it’s no surprise that it’s landing in the top picks for torrents. ExpressVPN makes most of the right privacy promises, and its speeds are very good. It also has a lot of other features beyond being good for torrents that make it worth your while, such as the smart DNS feature. ExpressVPN is officially based in the British Virgin Islands, it has an absolute ton of servers, but it does monitor bandwidth usage to get rid of bandwidth hogs, which might be a problem if you’re constantly downloading nightly builds of various Linux distros.

5. AirVPN – Honorable mention
Detailed real-time information about the network
Good pricing with many subscription options
Team is largely anonymous
AirVPN is either an excellent VPN for privacy, or the ultimate honey pot to attract online trouble makers, like free and open source software torrenters. The reason we say that is that AirVPN’s team is largely anonymous so it’s not clear who’s running the show. Still, this Italy-based VPN does have a good reputation and its speeds put it in our top 10. Its desktop interface is very bare bones, but it’s usable. Its network isn’t huge, but it is very economical and works well.

If you’ve read a number of these VPN articles, you know the drill by now. We test on three different days taking the average speeds we find in five different countries (each country is tested three times per day). Then we take all those daily averages to get an overall global average in megabytes per second. Then we compare that to the base speed without a VPN, and then express the result as a percentage how much of the base speed the global average maintains. If there are particularly standout speeds in a certain country or region we will generally call those out too.
The reason we don’t quote specific speeds is that these can vary by all kinds of factors such as your location, ISP, home network load and equipment, and so on. The percentages, however, give you a generally good idea of how much of a dip to expect when you connect to a VPN—there’s always a dip.
With that knowledge, however, you can be sure you’re getting good value for your money.
Most VPNs will likely be fine for torrents, but if you want the best of the best, these are our recommendations.How to pick a VPN for torrenting
There are a few hard-and-fast rules you need from a VPN when downloading torrents. Here’s what to look for:Blocking
First of all you want a VPN service provider that allows torrenting on their network. Most do, but there are a few notable exceptions such as Tunnel Bear, which actively blocks torrents.
Then there are VPNs that partially block torrents, especially on U.S. servers such as TorGuard. This VPN service recently settled a lawsuit brought against it by a consortium of Hollywood production companies after users of TorGuard were found torrenting files that weren’t free and open source software. As a result, TorGuard promised to no longer allow torrents on its U.S. servers.
TorGuard isn’t the only company that refuses torrents on its U.S. servers. Keep Solid recently promised to block torrents and piracy sites like The Pirate Bay, YTS, and RARBG on the U.S. servers of its service VPN Unlimited.
A number of other VPN services are also involved in pending legal action, including ExpressVPN and ZenMate, as reported by TorrentFreak. On top of that, many other VPN services don’t want to end up in a lawsuit like their competitors and actively disallow torrenting on their American servers.Service location
For that reason, we recommend using VPN services that are based outside the U.S., and from those VPNs you should use servers based in countries that are friendlier to torrents. This avoids the issue of dealing with torrents being blocked outright when all you want to do is load up Ubuntu on that new laptop. Most VPN services will specify which servers allow torrents, but a popular and easy choice is Sweden. The speeds are usually good, and most services include Swedish servers in their networks along with many other countries that are torrent-friendly.No-logs policy
The next thing you want is a VPN that has an ironclad no-logs promise from the service provider, because nobody wants to be exposed downloading free and open source software. That means that the service should include a promise not to maintain logs of any kind, with everything going to /dev/null—a non-existent directory on Linux systems that means all logs are permanently lost.
We say “promise” since there’s no real way to know for sure that a VPN isn’t logging your activity. You ultimately have to trust that they’re not doing it. This trust can come from a few factors, in order of reputability: The company’s no-logs promise has been proven by a court challenge, numerous third-party audits have verified the service’s claims, or you might just take the company at its word—yikes.Speed
Finally, after those details have been verified, you want a VPN with solid speeds. Torrents can take a long time to download as it is, depending on how many people are sharing the file. The last thing you want is to see your download slowed down by shoddy VPN speeds.
To get the VPN you need for torrenting, just put all those attributes together: allows torrents, absolute no-logs promise, torrent-friendly services and servers outside the U.S., and excellent speeds.FAQ
1.What is a VPN?
A VPN (virtual private network) encrypts your internet traffic and disguises your identity while browsing the internet. When used for torrenting, a VPN will anonymize your torrenting traffic and keep your ISP from potentially throttling your connection in the future.
Additionally, VPNs allow you to connect to servers all across the world. So if you’re looking to access location-restricted content, such as streaming services, you can connect to the appropriate country’s server and gain access that way.
2.How does a VPN work?
A VPN hides your IP address by redirecting it through a remote server hosted by the VPN company. To anyone looking in, the VPN server then becomes the source of your data instead of your actual location. These remote servers can be in your own country or located in different countries around the world. All of your network traffic from your computer to the VPN is sent over a secure and encrypted connection.
When connected to a VPN while browsing the internet, the VPN acts as a middleman between your computer and a website. Your computer sends a request to the VPN, which then passes it on to a website. The website then sends its response back to the VPN which forwards it through the secure connection to your computer. All of the traffic rerouted through the VPN shows as coming through their server rather than your own computer. This keeps your ISP and other third parties from snooping on your internet activity.
3.Are VPNs legal to use?
Yes! In most countries, including the United States, using a VPN is perfectly legal. Even though some websites might try to block VPN connections, they are still okay to use. Please note, while using a VPN is legal, some of the activities done while using a VPN might be illegal. Activities such as downloading pirated copyrighted content or accessing dark web markets are both illegal with or without a VPN.
4.Is Torrenting through a VPN safe?
Safety while torrenting comes down to two things: anonymity and protection from malware or other malicious files.
As far as anonymity goes, yes, you will be protected from any snooping outsiders or your own ISP’s restrictions on file torrenting by using a VPN. If you know and trust the P2P network you are using, torrenting with a VPN should be completely safe from prying eyes.
In regards to protection from malware and other malicious files, no. A VPN on its own will not protect you from accidentally downloading malicious files from P2P networks or torrent sites. For this, it is highly recommended that you use an antivirus program to help keep you safe.
5.Do VPNs track my browsing or store my data?
This depends entirely on the VPN provider you choose to use. There have been instances in the past of VPN providers spying on their users or collecting data. However, these were mainly free VPN services with no explicit no-logging policies.
When searching for a VPN, be careful to check the company’s website for a no-logging policy, third-party trust verification, and trustworthy user reviews. That being said, most of the major paid VPNs have clearly stated no-logging policies so it is typically best to stick with one of them.
6.How many servers should my VPN have?
That being said, most popular VPN providers offer between 3,000 to 5,000 servers. We recommend that you avoid any premium service with less than 1,000 servers as this could be an indication that the company is not yet well established, which could portend reliability issues.
LumaFusion, far and away the most feature-dense video editing app on iOS, has been updated to version 1.6. This latest release brings some notable enhancements to the table, including Gnarbox integration.
I’ve covered LumaFusion several times before, and have been impressed by the amount of features that it has built in for serious video editors. Version 1.6 continues to build on the foundation already established by previous versions, and creates a noteworthy hardware partnership in the process. Watch our hands-on video for more details.GNARBOX integration
The headlining feature of today’s 1.6 update is Gnarbox support. The Gnarbox, a portable battery-powered backup and editing system with built in storage, allows you to wirelessly transmit files to an iOS device. The unit comes with SD Card slots and USB ports letting it fetch and archive media from external sources.
After wirelessly connecting the Gnarbox to your iPad, you’ll be able to access media stored on the Gnarbox, along with media located on SD Cards and hard drives connected to the device. Via the Gnarbox app, users can transfer media from connected devices like SD Cards to the unit’s internal flash storage.Video walkthrough
Subscribe to 9to5Mac on YouTube for more videos
With today’s LumaFusion 1.6 update, users can now peruse and transfer media from the Gnarbox directly to an iPhone or iPad. A simple tap on the Gnarbox source inside of LumaFusion reveals all available media via its wireless connection. LumaFusion is even smart enough to display the Gnarbox’s current battery life.
Users have the option of viewing media streamed from the Gnarbox directly in the source viewer, setting in and out points along the way. When taking this approach, only the sections of media inserted into the timeline is downloaded to the iOS device, which can help save on space. Users also have the option of importing entire clips from either connected devices or media stored on the Gnarbox’s internal storage. Be sure to watch our hands-on video above for a demonstration of how it works.
During my testing I found file transfers to be a bit slow, but I’ve only tested it a handful of times. Version 1.0 of the Gnarbox along with its companion app feels a bit unpolished when compared to what I’ve seen from version 2.0, so here’s hoping that the enhanced hardware will make the process a bit faster and more streamlined. Once I get my hands on version 2.0 I plan on doing a full walkthrough of it and the LumaFusion integration.
Even with that said, however, it’s awesome to have direct access to the Gnarbox within LumaFusion without having to interface with any outside apps. It’s a very promising new feature that will likely be refined considering the track record of both companies.
Here is the full change log for 1.6:
GNARBOX Integration! If you’re a GNARBOX owner, you’ll be able to browse, preview, and trim media from your GNARBOX within the LumaFusion library. Then when you add clips to the timeline, just the portion needed for editing in the timeline is downloaded from the GNARBOX to LumaFusion. You’ll be able to continue editing while the media is downloading. Look for the GNARBOX 1.8.0 release in the App Store that enables this integration with LumaFusion.
New iCloud Photo Library media handling. Media from iCloud Photo Library that isn’t on your device can be added to the timeline immediately, and will be downloaded while you continue to work.
Library clips and source viewer now have a used-sections indicator showing what portions of the media are already used in the current project.
View link on export. For many export destinations, you can now tap View to open a web page to your rendered movie, making it easy to quickly share with others (note that in some cases the video may not be immediately ready for viewing).
All import and export providers have been re-written and have many internal improvements.
Added pull-to-refresh in library in cases where LumaFusion doesn’t show changes automatically.
Easier to rotate objects in the clip editor, and numeric values for rotate, move and scale are shown during gestures.
Added keyboard commands for the ‘Add Clip’ options in the timeline
iTunes library only shows clips that can be used by LumaFusion (downloaded and unprotected)
Voiceover clips default to ‘Master’ ducking setting
Added loop play support to source viewer
A number of issues with importing/exporting large files on some providers
Unable to login to Dropbox due to recent changes in Dropbox authentication
LUTs weren’t copied with Color settings in attributes clipboard
Cropping was not being saved in motion presets in all cases
Keyboard shortcut ‘C’ would not select clips if one already selected at playhead
Empty project wouldn’t change preview aspect ratio immediately
At NAB 2023 in Las Vegas, I previewed some additional exciting new features coming to LumaFusion, and I can assure you that fans of the app will be excited when these features ship.
LumaFusion version 1.6 is a free update for existing users. Those new to the app can purchase it from the App Store for $19.99. The 1.0 version of the Gnarbox is available now and users will need to download the latest 1.8 app update to enable LumaFusion support. Version 2.0 of the Gnarbox should be available any day now, and we will update you once it’s available.

Modern-day customers like to make more informed purchase decisions by cross-checking a product or service. They like to do extensive research before investing their hard-earned money anywhere. Speaking of insurance policies, today’s smart consumers will go through multiple plans and check the policy details, premium amount, coverages and benefits, and the reviews of each before signing a contract.
Therefore, to cater to the unique demands and shifts in buying patterns, insurance companies need to target their potential clients at every stage of the buying funnel to remain competitive and build brand identity.5 Ways Digital Marketing Helps Insurance Companies Grow
This article will discuss the best digital marketing practices to boost brand awareness for your insurance company.Create Updated Buyer Personas
Define your customers by answering questions like what they want, what are their interests, where are they coming from, who are the final decision-makers, what are their job roles, how old are they, and so on.
Segment your buyer personas by organizing all the gathered information about your clients. Look for similarities in the uncovered challenges and goals, and decide how many audience personas will be enough to achieve your marketing objectives. You don’t have to cover every user or client right now. Try to segment our buyers based on their job roles, the industries they belong to, their age groups, gender, and more. This step may be the most time-consuming, but it gets half your job done.
Create unique names and stories for every buyer persona to develop a full picture. In this way, you can give yourself a complete buyer profile to work with, thus knowing whom you are targeting and what their pain points are.
Segregate your buyer personas into three categories: their roles, their goals, and their challenges. This way, you can pull out the relevant parts for your marketing teams and sales reps, thus making their work easier in the upcoming days.
Finally, use your audience personas to devise tailored sales and digital marketing strategies. Try to relate each buyer persona with your sales and marketing teams, and correspond your campaigns with every customer’s favorite online platform. Hence, you can create more targeted and relevant ad campaigns and develop personalized content. You can also optimize your landing pages and speak to your buyers in their language.Build a High-quality Website
Design a top-notch website that showcases all your insurance policies and services appealingly. Make sure your visitors can find the right policy according to their needs and are also able to compare different schemes. Mention all the things covered by a specific policy and the packages your clients can avail of. Your website must resonate with your customers’ journey and help them understand your policy terms and coverages.Create and Publish Curated Content Create Thoughtful Social Media Campaigns
Marketing through various social media channels, including Facebook, Instagram, LinkedIn, WhatsApp, etc., has become indispensable for any smart insurance company. You don’t want to miss out on targeting and reaching the millions of social media users active for long hours every day. Besides, social media marketing is one of the fastest ways to grow your market size by reaching a global audience, which is not otherwise possible through traditional marketing.
Every platform needs a different treatment, so your social media marketing team needs to develop unique and innovative strategies for every platform. You can also execute more thoughtful and effective campaigns by tracking and monitoring the performances of your strategies and campaigns.Convert Your Website Users into Clients Final Words
To conclude, impactful digital marketing tactics will help create a higher impact among your prospects and help generate high-quality users. Through robust content strategies, you can fine-tune your insurance marketing products and services for effective targeting. Let your clients learn the ins and outs of your unique insurance products and policies, and give them a reason to buy from you.
Introduction to AWS EBS
The following article provides an outline for AWS EBS. EBS, called Elastic Block Store, is a block storage system used to store data. Designed for mission-critical systems, EBS provides easy scalability to petabytes to data. We all are familiar with the hard disk drive that we usually use for storing large chunks of data over the machines; EBS can be considered the same as a hard drive over the cloud that provides block storage for use.
Start Your Free Data Science Course
Hadoop, Data Science, Statistics & othersVolume Types of AWS EBS
Let us try to understand what exactly a block storage volume is under which EBS is working; block storage volume works similarly as a hard drive; we can store any type of files over there. EBS having the auto replication property helps from data being lost. EBS comes out with major 4 volume types.1. EBS General Purpose SSD (gp2)
This is the default EBS Volume provided; it has a well-balanced mixture over price with performance. For small I/O operations, SSD solid-state drive is much faster than HDD. The volume size for this ranges over 1GB -16TB. The performance is measured over Input Output per Second(IOPS); the EBS volume provides a ratio of 3 IOPS per GB.2. EBS Provisioned IOPS SSD 3. Throughput Optimized HDD(st1) 4. Cold HDD
Note: We can take a snapshot of the replica image of any EBS volume that we are creating; we can use these snapshots to create a new EBS volume over other instances. Also, they can be used as a backup of our volumes as well that are stored over s3.How to Setup and Use AWS EBS?
Let’s see the insights of Amazon EBS try to understand to install and use EBS.
Following Steps over AWS Console:
Step 1: Open the EC2 console of Amazon.
Step 2: Select the region where we want to create our volume.
Step 3: Choose the Elastic Block Store, and Volumes from the navigation pane.
Step 5: From the Volume, type chooses the type to volume we want to add into.
Step 6: Choose the appropriate size for that volume.
Step 7: Set the maximum IOPS that the volume should support.
Step 8: Check the availability Zone into which we want to create the volume; they can be attached with the instance in the same zone.
Step 9: Choose to Create Volume; once the volume is Available, we can attach it without instance and can start using it.
Attach the above made EBS with the Instance by the following ways:
Open the EC2 console.
Check for Elastic block store, volumes in the navigation pane.
Select the available volume and choose action; attach the volume.
Configure the details such as device name, Instance Id, and choose Attach.
Connect to the instance, and the volume is attached to it.
Once this process is done, we will be able to work with our EBS volumes inside the instances.Advantages of AWS EBS
Easy to Use: Since they can be easily created, attached, and monitored, EBS is easy to use. EBS allows us to increase storage, tune performance and change the volume as per the demand.
Data Storage: Storing data after any operation is easily possible with the help of EBS which makes it an efficient choice.
Cost-Effective: Since it comes with lots of volume-type options making it is cost-effective for the type of data we have.
AWS Integrated: It is integrated with all the services of AWS that makes easy availability under a roof, so the security, storage, networking, everything is integrated into one place.
