AWS, Containerisation and Kubernetes deployments

1st December 2023

Summary of a Containerization and Kubernetes Deployment Strategy on AWS. A difficult area, which requires a lot of specialised skills and Agile processes to discover, fail, deploy, improve and manage.

Objective: Enable efficient and scalable application deployment, management, and orchestration through the adoption of containerization and Kubernetes on the AWS cloud platform.

Key Components:

Containerization Framework:

  1. Description: Adopt containerization using Docker to package applications and their dependencies into lightweight, portable containers.
  2. Implementation Steps:
    • Containerize existing applications incrementally.
    • Develop new applications with containerization in mind.
    • Utilize Docker images for consistency across development, testing, and production environments.

AWS Container Services:

  1. Description: Leverage AWS container services, including Amazon Elastic Container Service (ECS) and Amazon Elastic Kubernetes Service (EKS), for efficient container orchestration and management.
  2. Implementation Steps:
    • Assess the suitability of ECS or EKS based on specific application requirements.
    • Implement ECS for simpler container orchestration or EKS for a fully managed Kubernetes environment.
    • Integrate with AWS Fargate for serverless container deployments.

Infrastructure as Code (IaC):

  1. Description: Implement Infrastructure as Code practices to automate the provisioning and configuration of container-related resources on AWS.
  2. Implementation Steps:
    • Use AWS CloudFormation or Terraform to define and manage infrastructure.
    • Store infrastructure code in version-controlled repositories for traceability and reproducibility.

Continuous Integration/Continuous Deployment (CI/CD):

  1. Description: Implement CI/CD pipelines for automated testing, deployment, and scaling of containerized applications.
  2. Implementation Steps:
    • Utilize AWS CodePipeline, AWS CodeBuild, and AWS CodeDeploy for building, testing, and deploying containerized applications.
    • Integrate CI/CD pipelines with container registries such as Amazon ECR.

Monitoring and Logging:

  1. Description: Implement robust monitoring and logging solutions to gain insights into containerized application performance and health.
  2. Implementation Steps:
    • Utilize AWS CloudWatch for monitoring container metrics.
    • Implement centralized logging with Amazon CloudWatch Logs or integrate with third-party logging solutions.

Security Best Practices:

  1. Description: Implement security best practices to safeguard containerized applications and underlying infrastructure.
  2. Implementation Steps:
    • Leverage AWS Identity and Access Management (IAM) for fine-grained access control.
    • Implement network segmentation using Virtual Private Cloud (VPC) configurations.
    • Regularly update container images to address security vulnerabilities.

Scalability and High Availability:

  1. Description: Design containerized applications for scalability and high availability to meet varying workloads.
  2. Implementation Steps:
    • Implement auto-scaling policies for dynamic resource allocation.
    • Utilize multiple Availability Zones to ensure high availability and fault tolerance.

Training and Documentation:

Description: Provide training for the development and operations teams on containerization, AWS container services, and best practices.

Implementation Steps:

  1. Develop comprehensive documentation covering containerization workflows, AWS service configurations, and troubleshooting guidelines.
  2. Encourage continuous learning and exploration of new AWS features related to containerization.
