The EKS Disaster Recovery project ensures the continuity of Amazon EKS Kubernetes clusters by implementing a multi-region deployment strategy, backup and restore mechanisms, and automated failover procedures.
Tools and Services Used
AWS Services
IAM: AWS Identity and Access Management (IAM) is a service for managing user permissions and access to AWS resources securely.
VPC: Amazon Virtual Private Cloud (VPC) enables users to create isolated, customizable network environments within the AWS cloud.
EC2: Amazon Elastic Compute Cloud (EC2) provides scalable virtual servers in the cloud, allowing users to run applications with flexibility and control.
EKS: Amazon EKS (Elastic Kubernetes Service) simplifies containerized applications' deployment, management, and scaling using Kubernetes.
ECR: Amazon Elastic Container Registry (ECR) is a fully managed Docker container registry, making storing, managing, and deploying Docker container images easy.
RDS: Amazon Relational Database Service (RDS) offers managed relational databases, supporting various database engines for scalable and secure data storage.
ELB & ASG: Elastic Load Balancing (ELB) distributes incoming application traffic, and Auto Scaling Groups (ASG) automatically adjusts the number of EC2 instances based on demand.
CloudFormation: AWS CloudFormation allows users to define and deploy infrastructure as code, automating the creation and management of AWS resources.
Route53: Amazon Route 53 is a scalable and highly available Domain Name System (DNS) web service, that provides domain registration and routing capabilities.
Tools
Docker: Docker is a platform for developing, shipping, and running container applications, promoting consistency across different environments.
Python (Flask): Flask is a lightweight web framework for Python, commonly used to build and deploy web applications.
Kubernetes: An open-source container orchestration platform, Kubernetes automates the deployment, scaling, and management of containerized applications.
AWS CLI: The AWS Command Line Interface (CLI) is a unified tool for managing AWS services, providing a streamlined interface for command-line interactions.
MySQL: A popular open-source relational database management system, MySQL is widely used for scalable and reliable data storage within AWS.
Git & GitHub: To manage and share source code repositories, track changes, and collaborate on projects with features like pull requests, issues, and actions.
