2. Navigate to the EC2 service and launch an EC2 instance using the console. 🚀

   

   

3. Connect to the EC2 instance using SSH. 🔒

   

   

4. Create an S3 bucket and upload a file to it using the AWS Management Console.

   • Review the details before clicking on the "Upload" button to upload your file.

   • Once the upload is complete, you can see the file in your S3 bucket.

5. Access the file from the EC2 instance using the AWS Command Line Interface (AWS CLI).

   • Install the AWS CLI. 💻

     To install the AWS CLI, you can use the following commands:

       sudo apt update
       sudo apt install awscli

   • Once installed, open a terminal and run the commandaws configure to configure your account credentials.

       aws configure
     

     

   • List S3 buckets using the commandaws s3 ls.

       aws s3 ls
     

     

   • You can use theaws s3 cp command to copy the file from your S3 bucket to your EC2 instance and view the content of the file using the cat command.

Task-02

Create a snapshot of the EC2 instance and use it to launch a new EC2 instance.

1. Select the EC2 instance that you want to create a snapshot of.

   

2. Create a snapshot of the selected EC2 instance. 📸

3. Use the snapshot to launch a new EC2 instance.

   

   

   

   • In the right side, click on Actions and select 'Create image from snapshot'.

     

   • In the "Create Image from snapshot" window, enter a name and description for the image.

     

   • Click on 'create image'.

   • In the "Launch Instance" window, choose the configuration options for the new instance.

   • Choose the VPC and subnet you want to launch the new instance in.

   • In the "Add Storage" section, you can choose to modify the storage volumes as per your requirements.

   • Review the instance details and click "Launch instance" to launch the new instance.

     

     

     

Connect to instance using SSH:

Here, login as the user "ubuntu" rather than the user "root".

Download a file from the S3 bucket using the AWS CLI.

Use the aws s3 cp command to download the file from your S3 bucket to your EC2 instance.

aws s3 cp s3://BUCKET_NAME/PATH/TO/FILE /PATH/TO/LOCAL/FILE

Verify that the contents of the file are the same on both EC2 instances.
