What is EC2 in cloud computing? Complete Tutorial

Introduction of Amazon EC2 in cloud computing

The Amazon EC2 in cloud computing platform includes 750+ instances on a virtual server and different types of support and workloads. The user can choose the latest processors, storage, networking, operating system, and purchase model architecture for their requirements. All packages are pre-configuration templates

What is Amazon EC2?

EC2 in cloud computing is a part of Amazon Web Services that is a full form of Elastic Compute Cloud (ECC). EC2 is a cloud computing service that is provided by the AWS cloud service provider. On the EC2 server, you can deploy the applications without any physical infrastructure. Configure the EC2 instances with security, subnets, and groups. You can configure the applications on demand with the help of EC2 instances.

Use case for Amazon EC2

EC2 of Amazon provides a good cloud computing platform for the company’s applications. It provides servers, networking, and security in a virtual environment for organizations. EC2 provides on-demand services and is highly suitable for all use cases.

• Deploying Applications: You can deploy your applications without maintaining the infrastructure.
• Web Servers: You can deploy your web server in the EC2 instances based on demand.
• Hybrid cloud environment: Deploy your web applications in EC2 instances and you can connect your database, which are deployed on existing server.
• Batch Processing
• High-performance web server
• Media transcoding
• Input/output applications
• Cost effective

Amazon EC2 components:

Operating System Support

Amazon EC2 supports many operating systems that we need to play for license. Red Hat, Oracle, UNIX, Windows Server, and so on.

Security

How do I create EC2 instances?

EC2 creation is very simple. There are a few steps to follow to create an EC2 instance. If you are a beginner, then you want some guidelines to create an instance. Here are some steps to follow:

• Login to your AWS account and click the service option, which is available in the top left corner.
• Under the drop-down menu list, the computer category will show. Click on EC2, and the EC2 dashboard will open.
• On the right side of the EC2 dashboard window, under the Launch instance, click the Launch instance button.
• Step 1: Choose Amazon Machine Image (AMI) and then select the operating system where you want to work.
• Step 2: Select an instance type that you want to use and click the radio button in front of it. Click Nest to view the configuration instance details.
• Step 3: Review the settings, then add the storage button. In this step, you can edit the default settings as per your requirements. You can change the size of the free space available.
• Step 4: You can add a new tag as per your requirements. Click on the add tag and new tag buttons, which can easily identify your applications. Once the tag has been added, click and configure the security group option.
• Step 5: In this step, you can configure the security option. Here you can add rules like types, protocol, port range, and so many more. After that, click on the review and launch buttons.
• Step 6: After reviewing all settings, click the launch button. Windows will be open after selecting the key pair or existing key pair.
• Step 7: In the opening window, create a new key pair from the drop-down list. Provide the key pair name that you want to give, like instance_key_pair.
• Step 8: Click the download key pair; after downloading, select the existing key pair or create a new key pair; and click the launch instance button.
• It will take time to launch, and after that, you will get notifications.
