Creating an EC2 Amazon Instance from an AMI: A Guide
Creating an EC2 Amazon Instance from an AMI: A Guide
Creating an Amazon Elastic Compute Cloud (EC2) instance from an Amazon Machine Image (AMI) is a key skill for any data scientist or software engineer working with AWS. This “How-To” guide aims to provide you with a step-by-step rundown of the process.
What is an Amazon Machine Image (AMI)?
An Amazon Machine Image (AMI) is a template that contains a software configuration (i.e., an operating system, application server, and applications). From an AMI, you launch an instance, which is a copy of the AMI running as a virtual server in the cloud. You can then use this instance just like you would use any other server.
Step 1: Open the Amazon EC2 Dashboard
The first step is to open the AWS Management Console and then open the Amazon EC2 dashboard. You can do this by navigating to Services > EC2.
Step 2: Choose an AMI
From the EC2 dashboard, navigate to “Launch Instance.” You will be presented with a list of AMIs. You can choose one from this list or search for a specific one using the search bar.
Step 3: Choose an Instance Type
After selecting your AMI, you’ll need to choose an instance type. The instance type determines the hardware of the host computer used for the instance. Each instance type offers different compute, memory, and storage capabilities. Select the instance type that meets your requirements, and then choose “Next: Configure Instance Details.”
Step 4: Configure Instance Details
This step involves specifying configurations for your instance. These include the number of instances, the networking settings, and the IAM role, among others. Once you’re done, select “Next: Add Storage.”
Step 5: Add Storage
Here, you can add storage to your instance. You can specify the type and size of the storage and whether it should be deleted upon termination of the instance. Once you’ve configured the storage, choose “Next: Add Tags.”
Step 6: Add Tags
Tags can be added to organize your instances. After adding relevant tags, select “Next: Configure Security Group.”
Step 7: Configure Security Group
Security groups act as a virtual firewall for your instance. In this step, you specify the rules for traffic to and from your instance. You can add rules to allow specific traffic (for example, SSH traffic) from specific sources. Once you’ve set up your security group, select “Review and Launch.”
Step 8: Review and Launch
In this final step, review your instance configuration. Ensure everything is set up as per your requirements. If everything looks good, choose “Launch.” You will be asked to select a key pair that will be used to connect to your instance. After selecting a key pair, choose “Launch Instances.”
And that’s it! You’ve successfully created an Amazon EC2 instance from an AMI. Your instance will start up, and soon, you’ll be able to connect to it.
Creating an EC2 instance from an AMI is a fundamental aspect of working with AWS. Understanding this process can help data scientists and software engineers efficiently deploy applications and workloads in the cloud. Keep practicing and exploring AWS to become more proficient in cloud computing.
