AWS EC2 Automation

Instance Types

1. General Purpose Instances (e.g., T3): Balanced computing power for diverse applications.
2. Compute Optimized Instances (e.g., C5): High-performance CPUs for compute-intensive tasks.
3. Memory Optimized Instances (e.g., R5): Designed for memory-intensive applications.
4. Storage Optimized Instances (e.g., I3): High I/O performance for storage-heavy workloads.
5. Accelerated Computing Instances (e.g., P4): Instances with powerful GPUs for tasks like machine learning.

Steps to Launch Template in AWS EC2

An AWS EC2 Launch Template is a configuration template that simplifies the process of launching instances (virtual servers) in the Amazon Elastic Compute Cloud (EC2). It allows you to define a set of parameters for your instances, such as the AMI (Amazon Machine Image), instance type, security groups, key pair, and other settings. Using a launch template can streamline and standardize the instance creation process.

Step 1: Navigate to EC2 Console

1. Log in to the AWS Management Console.
2. Navigate to the EC2 dashboard.

Step 2: Create a Launch Template

1. In the EC2 dashboard, select "Launch Templates" from the navigation pane.
2. Click on the "Create Launch Template" button.
3. Enter a name for your launch template.
4. Configure the template settings:AMI (Amazon Machine Image): Select the desired AMI for your instance.Instance Type: Choose the instance type that suits your requirements.Key Pair: Select or create an EC2 key pair for SSH access.Configure other settings like networking, storage, security groups, IAM role, etc.
5. Optionally, you can configure advanced settings like user data, tags, and monitoring.
6. Click "Create launch template" to save your configuration.

Step 3: Launch an Instance with the Launch Template

1. Once your launch template is created, go back to the EC2 dashboard.
2. Click on the "Launch Instance" button.
3. In the "Choose an Amazon Machine Image (AMI)" step, select "Launch Templates" on the left sidebar.
4. Choose the launch template you created from the list.
5. Specify the number of instances you want to launch and other instance details.
6. Continue through the wizard, reviewing and configuring settings as needed.
7. Complete the process, and click "Launch Instances" to initiate the launch.

Step 4: Monitor and Manage Instances

1. After launching, you can monitor your instances in the EC2 dashboard.
2. If needed, you can modify your launch template and create a new version.
