Deploy a containerized application with AWS container services by creating and configuring ECR, ECS, and Fargate resources, including clusters, task definitions, and networking rules.

Fix connectivity for an EC2 instance in a data center VPC by attaching the internet gateway and updating route tables, then verify reachability via the EC2 public IP and HTTP.

Create a symmetric AWS KMS key, encrypt and decrypt a sensitive file using the key, and verify file integrity with diff and checks.

Launch and configure an AWS EKS cluster with custom settings, create the cluster IAM role, select default VPC, adjust subnets, remove add-ons, and monitor the cluster until active.

Practice setting up a NAT gateway in a VPC with public and private subnets, configure route tables, subnet associations, attach an internet gateway, and validate using an S3 bucket.

Set up public and private S3 buckets, trigger a Lambda function on uploads to copy files to the private bucket, and create a DynamoDB table with an IAM role.

Deploy resources with CloudFormation to create SQS queues, SNS topic, and a Lambda function; zip index.py, update Lambda code, configure environment variables, and test the invocation.

Create and deploy an AWS Lambda function using CloudFormation, including an IAM role and the DevOps Lambda, then test the function by invoking it and inspecting the response.

Automate secure log collection from a private EC2 to a public EC2, then push to a secure S3 bucket by configuring VPCs, peering, IAM, and a cron-based transfer workflow.

perform day 50 hands-on cloud lab by expanding an EC2 volume from 8 GiB to 12 GiB in the AWS console, then SSH into the instance to verify.
