What have you implemented on the AWS cloud platform…

Implemented automation of infrastructure and application deployment in AWS using IaaS and PaaS services.

Main areas of work:

Infrastructure as Code (IaC): Using AWS CloudFormation and Terraform to describe and manage infrastructure (VPC, EC2, RDS, S3, etc.).
CI/CD pipelines: Setting up AWS CodePipeline, CodeBuild, CodeDeploy for automatic build, testing, and deployment of applications. Integration with GitHub/GitLab.
Containerization: Deploying and managing containerized applications using Amazon ECS and Amazon EKS. Configuring Fargate for serverless containers.
Monitoring and Logging: Implementing Amazon CloudWatch for metrics and logs collection, setting up alerts. Using AWS X-Ray for tracing distributed systems.
Configuration Management: Applying AWS Systems Manager for centralized management of EC2 instances.
Security: Configuring AWS Identity and Access Management (IAM) for access control, using AWS Security Groups and NACLs for network security, implementing AWS Secrets Manager for secure secret storage.
Serverless Computing: Developing and deploying functions on AWS Lambda.
Database Management: Setting up and migrating to Amazon RDS (PostgreSQL, MySQL) and Amazon DynamoDB.
Cost Optimization: Analyzing resource consumption with AWS Cost Explorer and optimizing expenses.

Example of a pipeline on AWS CodePipeline:

# Example of a pipeline definition in CloudFormation
Resources:
  MyPipeline:
    Type: AWS::CodePipeline::Pipeline
    Properties:
      Name: my-application-pipeline
      RoleArn: !GetAtt CodePipelineServiceRole.Arn
      ArtifactStore:
        Type: S3
        Location: !Ref PipelineArtifactBucket
      Stages:
        - Name: Source
          Actions:
            - Name: SourceAction
              ActionTypeId:
                Category: Source
                Owner: ThirdParty
                Provider: GitHub
                Version: '1'
              OutputArtifacts:
                - Name: SourceOutput
              Configuration:
                Owner: my-github-user
                Repo: my-application-repo
                Branch: main
                PollForChanges: true
                AccessToken: "{{resolve:secretsmanager:github_token:SecretString:token}}"
        - Name: Build
          Actions:
            - Name: BuildAction
              ActionTypeId:
                Category: Build
                Owner: AWS
                Provider: CodeBuild
                Version: '1'
              InputArtifacts:
                - Name: SourceOutput
              OutputArtifacts:
                - Name: BuildOutput
              Configuration:
                ProjectName: !Ref CodeBuildProject
        # ... other stages (Test, Deploy)

Using Terraform for VPC deployment:

# terraform.tf
resource "aws_vpc" "main" {
  cidr_block = "10.0.0.0/16"
  enable_dns_hostnames = true
  enable_dns_support = true

  tags = {
    Name = "main-vpc"
  }
}

resource "aws_subnet" "public" {
  vpc_id     = aws_vpc.main.id
  cidr_block = "10.0.1.0/24"
  availability_zone = "us-east-1a" # Example AZ

  tags = {
    Name = "public-subnet-us-east-1a"
  }
}

# ... other resources (Internet Gateway, Route Tables, etc.)
