Suggested March 2024 How To Use And SetupIntroduction 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.

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.
Security: The Encryption and Decryption policy for EBS makes it amazingly secure over the network making the data secure.AWS EBS Pricing
EBS comes with dynamic and cost-effective pricing that helps users to select the volume of data based on their data load. With EBS, we pay only what we use.
For general purpose SSD (gp2), the pricing comes as $0.1 per GB month of provisioned storage.
For EBS Provisioned IOPS SSD (io1) $0.125 per GB-month of provisioned storage. $0.065 per provisioned IOPS month.
For EBS Throughput Optimized HDD(st1), $0.045 per GB-month of provisioned storage.
For EBS Cold HDD (sc1), $0.025 per GB-month of provisioned storage.
For detailed pricing, refer to the Amazon EBS pricing docs below:
The Document above has all the details about the various pricing.
AWS provides many functionalities that make things easier for us, some of the technologies are AWS EBS;
Amazon Auto Scaling
Amazon Elastic MapReduce (EMR)
From the above article, we saw how EBS can be used for storing data with the feature of having an adjustable volume size over the requirement. The data is secure and saved accordingly, making it easy for a developer and an application to perform well.Recommended Articles

Firewalls are an integral component of every contemporary computer system, safeguarding the network and protecting the system from illegal access. We’ll take a deep dive into the realm of Linux firewalls and learn how to configure one in this post.
Before we involve into the technical details of establishing a firewall in Linux, let us clarify what a firewall is and why it is so important!
A firewall is a network security device that monitors and restricts network traffic based on predefined security rules. A firewall’s principal function is to block unauthorised access to a computer system or network while still allowing authorised access. It functions as a gatekeeper, controlling who and what may enter and depart a network.
There are two major choices for configuring a firewall in Linux: iptables and firewalld.
‘iptables’ is a command-line programme for managing the Linux kernel firewall. For many years, it was the default firewall for Linux servers and is still extensively used today.
‘firewalld’ is a more modern approach to managing firewalls in Linux. It is a dynamic daemon that provides a D-Bus interface for managing firewall rules, and it is used by many Linux distributions as the default firewall.
Now let’s dive into the steps required to set up a firewall in Linux using both iptables and firewalld.Using ‘iptables’ to Create a Firewall
To begin setting an iptables firewall, first ensure that it is already installed on your system. Although iptables is present in most Linux distributions, it is always a good idea to double-check.
Open a terminal and type the following command to see if iptables is installed on your system: sudo iptables -L
If iptables is not already installed on your machine, use the following command to install it: sudo apt-get install iptables
You may begin setting the firewall once you have validated that iptables is installed on your system.
The initial step in iptables configuration is to establish the default policies for incoming and outgoing traffic. The default policy determines what happens to packets that do not match any of the rules in the firewall.
To set the default policies to drop all incoming and outgoing traffic, run the following commands −sudo iptables -P INPUT DROP sudo iptables -P OUTPUT DROP
Once you have set the default policies, you can start adding rules to allow or block specific types of traffic. The basic syntax for adding a rule to iptables is as follows −sudo iptables -A [CHAIN] -p [PROTOCOL] --dport [PORT] -j [ACTION]
Let’s break down the components of the rule −
CHAIN − This specifies the chain in the firewall where the rule will be added. The three default chains in iptables are INPUT, OUTPUT, and FORWARD.
PROTOCOL − This specifies the protocol for the traffic. Common protocols include TCP, UDP, and ICMP.
PORT − This specifies the port number for the traffic.
ACTION − This specifies what should happen to traffic that matches the rule. Common actions include ACCEPT, DROP, and REJECT.
The following command, for example, would accept incoming SSH traffic (port 22) on the INPUT chain −sudo iptables -A INPUT -p tcp —dport 22 -j ACCEPT
Similarly, the following command would enable OUTPUT chain HTTP traffic (port 80) −sudo iptables -A OUTPUT -p tcp —dport 80 -j ACCEPT Using ‘firewalld’ to Create a Firewall
Another option for setting up a firewall in Linux is by using firewalld. Firewalld is a modern dynamic daemon that is used by several Linux distributions, such as CentOS, Fedora, and Red Hat Enterprise Linux, as the default firewall management tool.
The first step in configuring a firewall with firewalld is to see if it is already installed on your system.
Most recent Linux distributions come with firewalld pre-installed, however you may validate its presence in the terminal by typing the following command −sudo firewall-cmd —state
If firewalld is not already installed on your machine, use the following command to install it: sudo yum install firewalld
Once you confirmed that firewalld is installed on your system, you start configuring the firewall.
The first step in configuring firewalld is to check the default zone. The default zone is a predefined set of rules that govern the traffic allowed on the system. To check the default zone, run the following command −sudo firewall-cmd --get-default-zone
By default, the default zone is set to “public”. You can change the default zone by running the following command −sudo firewall-cmd --set-default-zone=zone
where “zone” is the name of the zone you want to set as default.
To allow incoming HTTP traffic, for example, you can use the following command −
The “–permanent” option makes the rule permanent, so it survives a reboot. If you do not use the “–permanent” option, the rule will be removed when the system is rebooted.
You can also allow specific ports by using the “–add-port” option. For example, the following command allows incoming traffic on port 22 for SSH −sudo firewall-cmd --add-port=22/tcp --permanent
After adding the necessary rules, make sure to reload the firewall for the changes to take effect −sudo firewall-cmd --reload
If you are using your computer in multiple environments, such as your work office network, a friends networks or just at home, you should know how to use a Proxy server. This guide will show you how to setup a proxy server on Microsoft Edge, Google Chrome, and Mozilla Firefox web browsers. As this guide is quite long, feel free to skip to the browser/browsers you use the most.
How to Erase a Recovery Partition on Windows 7, 8, and 10.
Proxy servers are basically a middleman in your connection to the Internet and can help protect your anonymity/privacy, they are also quite often used to get around IP blocks that may be restricting access to websites. If you would like a more in-depth rundown on how they work head on over to Wikipedia. For full setup guides, keep on reading below.
Note: If you don’t have a Proxy to use, Google ‘Free Proxy Server List’ and pick an option that best suits your location, anonymity, and speed requirements.How to Setup a Proxy Server on Google Chrome.
Setting up a Proxy server on Google Chrome is a strange affair as Chrome likes to hijack the Windows Proxy setup process, you’ll understand what we mean shortly.
First, open Google Chrome Settings using the 3 dots icon in the upper right-hand corner of the browser and choose Settings from the list.
Now that the Local Area Network (LAN) Settings window is open, set your proxy server. you can choose either: Automatic Configuration Script, or use a Proxy Server (Manual version, which you will need to enter the details of your chosen server)
Note: Entering this information will also enable a Proxy for Internet Explorer and any other Windows applications that use Proxy settings from Internet Explorer.How to Setup a Proxy Server in Firefox.
Firefox borrows Windows Proxy settings to a degree also, however you can also set up individual proxy settings that will only affect Firefox.
You should now see tons of proxy-related options. Firefox likes to use the system Proxy by default. (The one set in Windows) To manually set the proxy configuration for Firefox, choose Manual Proxy Configuration and enter your proxy details.
Note: Unlike most other browsers, Firefox lets you set different proxy servers and ports for all kinds of traffic. For example, HTTP, SSL, FTP. If you don’t want your proxy to affect specific addresses, you can add them to the No Proxy For text box. Just make sure to separate the addresses with a comma.
How to Setup a Proxy Server in Microsoft Edge.
Microsoft Edge works in the exact same way that Google Chrome does when setting up a Proxy server. It just hijacks the main Windows 10 Proxy.
This will automatically open the Windows 10 Settings app. As the rest of the setup is the same as setting up a Proxy on Windows 10, please use this guide. Setting up Proxy Server in Windows 10.How to Turn off a Proxy Server.
In all honesty, it is going to save you a lot more time setting up a Proxy server directly from the Settings app on Windows. The step by step guide on how to do that can be found here:
How to Setup a Proxy Server on Windows 10.
One important addition to Firefox has been the inclusion of a Permission Manager for Firefox. The Permission Manager of Mozilla Firefox will allow users to define the user’s own settings for the websites. For example, a user can set whether a website stores a user password, user’s location, cookies, show pop-up windows, and maintain data offline. The great thing about the Permission Manager is the level of customization that it offers and it is easy to configure. You can decide what data you want to share with websites!
So now a user can store their settings on save passwords, share location, set cookies, open pop-up windows, and maintain offline storage by following these steps in Permission Manager.
When the user opens the screen it displays the default permissions for all sites accessed in the web browser.
Let me introduce the user to the five options in the Firefox Permission Manager.
Store Passwords: Here a user can allow or block storing of passwords for any website. This has no impact on the third-party log-in helpers. This affects the default Firefox password. According to this, the user can allow or block the storing of passwords on individual sites or any other websites.
Share location: Firefox will submit the information to the websites if they support the Mozilla Firefox feature, which gathers additional information from users such as location and computer IP address. It always detects a computer’s IP address regardless of the setting. There are two options: Always Ask or Block. User can set block categories for some websites.
Set Cookies: Here two options are permitted like Block Cookies along with Allow for the session only. The site or all sites can set cookies if the user wants.
Open Pop-up Windows: This option I would like to recommend to the users. Put this option into the Block category because this will block all pop-ups across all websites.
Maintain Offline Storage: This should not be confused with the Web Browser cache. If the users have favorite’s website content in offline browsing mode, it might be handy. So offline storage is used to provide access to data when the browser is in offline mode.Configure Firefox Permission Manager settings for a particular website
When the user visits a website in Firefox, it displays the default permissions for all sites accessed in the web browser. However, when a user selects one of the sites in the Permission Manager, he can view information about the data that it stores about the user in the browser. Here’s how you can check the details of the information and configure your preferences via Permission Manager in Firefox.
Launch the Firefox browser.
Open a website in the new tab.
Choose More Information option.
Configure your Preferences for the website in the browser.
The Permissions icon is visible in the address bar of the Firefox browser.
Launch Firefox browser. Make sure it’s updated to the latest version.
Go to the website you visit frequently or enter its address in the address bar.
Now, switch to the Permissions tab and set the desired permissions for the site that you’re visiting. For example, you can set the permissions for the following.
Access your location: Firefox will submit the information to the websites if they support the Mozilla Firefox feature, which gathers additional information from users such as location and computer IP address. It always detects a computer’s IP address regardless of the setting. Select the desired option for yourself (Always Ask/Allow/Block.
Set Cookies: Here you can select between Allow/Allow for session only/Block options.
Open Pop-up Windows: We recommend users choose the Block option for this setting to block all pop-ups across all websites.
Likewise, you can configure options for other settings like Open pop-up windows, Send Notifications, Share the Screen, install add-ons, autoplay, Use the Camera, Use the Microphone, etc.
Hope it helps!
We are living in an information overabundance. Welcome to the Data Age, where we make 2.5 quintillion bytes (otherwise called exabytes) of information consistently.
Introducing the misrepresentation of the day: “That is a ton of information!”
The present organizations use the information to pursue basic choices.
Information-driven choices are educated choices and have a more prominent likelihood of coming out on top.What is AWS Redshift?
AWS Redshift is a well-known information warehousing arrangement that can deal with information on an exabytes scale.
You might be thinking about help for various use cases, for example, handling the ongoing investigation, consolidating different information sources, log examination, or more.
Made conceivable by its Massively Parallel Processing (MPP) innovation, Redshift can execute procedures on an immense volume of information at lightning speed — while regularly costing just a small portion of what contenders like Prophet and Teradata charge for identical items.
Each Amazon Redshift information stockroom incorporates a bunch of hubs coordinated into a group.
Each group runs its Redshift motor and holds something like one data set.
Even though Redshift is an examination data set, it’s sufficiently adaptable to permit cloud clients to run conventional social data sets.
Moreover, it’s a segment-situated data set that stores information in a columnar configuration that supports the presentation when it peruses and composes information.
Redshift is a completely overseen information stockroom, giving clients the limit, in any case, a couple of gigabytes of information and ultimately scaling it to petabytes.
It’s additionally called an OLAP-style (Online Analytical Processing) information base.AWS Redshift Benefits
AWS Integration − AWS is one of the three generally famous and frequently utilized cloud arrangements (the other two being Purplish blue and Google Cloud), and Redshift functions admirably with Amazon Web Administrations.
Information Encryption and Security − Amazon offers many layers of safety to its clients, including access control, virtual confidential mists, and intentional information encryption; the client can conclude what needs encryption.
Speed − Redshift offers unrivaled speed because of MPP innovation.
Handily Sent − You can convey a Redshift bunch in minutes and for a small part of the expense of a conventional information distribution center.
Standard, Reliable Reinforcements − Amazon conducts normal, predictable reinforcements prepared for use in reestablishes and information recuperation activities. Moreover, Amazon stores this information across a bunch of areas.
You Can Utilize Natural Apparatuses − Redshift utilizes PostgreSQL, so all SQL questions work with it. Additionally, you can pick any ETL (Concentrate, Change, Burden), SQL, and Business Insight (BI) devices you normally use.
Dull Undertaking Mechanization − Nothing is as irritating and tedious as playing out a similar disturbing nearly nothing (yet totally vital) errands consistently (or week, month, or makes no difference either way). Redshift allows you to mechanize these bothersome redundant positions, liberating your staff to handle the additional difficult obligations.AWS Redshift Cost
Costs start as low as USD 0.25 every hour for a terabyte of data, and you can scale starting there. The continuous assessment information was given by Amazon’s Redshift esteeming page.
Amazon, in like manner, offers a compensation more-just as-costs-emerge assessing structure, which changes with your necessities.
Outline. With Amazon Redshift, you can begin at $0.25 each hour and scale up to petabytes of information and many simultaneous clients. Pick common decency for your business needs, with the capacity to develop capacity without over-provisioning registering, or stockpiling.How Would I Set Up Amazon Redshift?
Setting up Amazon Redshift is simple
Get an AWS account: On the off chance that you do not have an Amazon Web Administrations account as of now, set one up.
Open a firewall port: Redshift needs an open port, and it commonly defaults to port 5439, so ensure that the port is accessible in your firewall. On the other hand, you can recognize an alternate open port in your firewall when you make your group; however, be cautioned: you can’t change the port number after making the bunch.
Award consent to get to other AWS assets: You want to allow Redshift to get to other AWS assets. Either make a devoted IAM job joined to a Redshift bunch or give the AWS access key to an IAM client with the usual consent.
Send off a Redshift bunch: Sign on as the client with the necessary consent and open the Amazon Redshift console.
Pick the area: Select the locale where you need to make your most memorable bunch.
