Ποια είναι η εμπειρία σας με το AWS;

I have extensive experience with AWS, including implementing CI/CD, managing infrastructure as code (IaC), and monitoring. I have worked with key services to build scalable and reliable solutions.

Services I have worked with:

• Compute: EC2, Lambda, ECS, EKS
• Storage: S3, EBS, RDS, DynamoDB
• Networking: VPC, Route 53, ELB (ALB, NLB)
• Databases: RDS (PostgreSQL, MySQL), DynamoDB
• Management and Monitoring: CloudFormation, Terraform, CloudWatch, CloudTrail, IAM, Secrets Manager
• CI/CD: CodePipeline, CodeBuild, CodeDeploy, Jenkins on EC2/EKS

Project examples:

• Deployment of microservice architecture on EKS using Terraform for IaC.
• Setting up CI/CD pipelines with CodePipeline and CodeBuild for automatic deployment of applications on ECS Fargate.
• Implementing centralized logging and monitoring using CloudWatch Logs and CloudWatch Metrics.
• Cost optimization on AWS by choosing the right EC2 instances and using S3 lifecycle policies.
• Managing security with IAM roles, groups, and policies.

IaC technologies I have worked with:

// Example Terraform code to create an EC2 instance
resource "aws_instance" "webserver" {
  ami           = "ami-0abcdef1234567890" # Replace with your AMI ID
  instance_type = "t2.micro"
  tags = {
    Name = "webserver-prod"
  }
}

Monitoring systems:

Tool	Application
CloudWatch	Metrics collection, logs, alert setup
Prometheus	Metrics collection with Kubernetes/ECS
Grafana	Metrics visualization

My experience enables me to solve tasks related to deployment automation, infrastructure management, and ensuring high availability and reliability of applications in the AWS cloud.
