Use case
Migration from
EC2 to EKS
Voyage Vista, a rapidly growing SaaS startup, required a scalable and reliable infrastructure solution to deploy their micro services based containerized application.
To meet their needs, the decision was made to implement an infrastructure based on Amazon Elastic Kubernetes Service (EKS).
1. Motivation for Migration to AWS EKS
Scalability:
Managing increasing demands of the application workload is complex and time-consuming. Amazon EKS offers the advantage of leveraging Kubernetes, which provides efficient orchestration and auto-scaling capabilities reducing manual efforts and ensuring optimal performance.
High Availability:
Conventional setups lack multi-zone deployment, automated failover, and load balancing, causing downtime and performance gaps during failures or high traffic. Amazon EKS provides multi-zone deployment, failover automation, and load balancing to minimize downtime and maintain reliability.
Security:
Ensuring data security and access control during migration is a challenge. Amazon EKS offers enhanced security through role-based access control (RBAC) and network policies, safeguarding applications and data.
Automation:
Manual deployment and updates are time-consuming and prone to errors. Amazon EKS integrates with DevOps best practices, enabling automated deployments and CI/CD pipelines for efficient and consistent application management.
Cost Optimization:
Inefficient resource allocation and high infrastructure costs can strain budgets. Amazon EKS optimizes costs by dynamically allocating resources and using AWS pricing models, ensuring cost-effectiveness and efficient resource utilization.
2. Solution Design and Implementation
Cluster Architecture:
A multi-Availability Zone (AZ) EKS cluster is designed as it ensures high availability by spanning AZs and preventing single-point failures.ALB for Ingress Traffic:
ALB efficiently handles traffic originating from the internet, taking advantage of its advanced routing and SSL/TLS termination capabilities.
Ingress Controller for Kubernetes Native Management:
An Ingress controller specializes in managing traffic within the Kubernetes cluster, providing Kubernetes-native features like SSL/TLS termination and URL rewriting.
Application Deployment:
Containerized applications are deployed to the EKS cluster using Kubernetes manifests or Helm charts. Deployment strategies such as rolling updates or blue/green deployments are implemented.Networking:
Amazon Virtual Private Cloud (VPC) is used to isolate the EKS cluster, connecting via AZ subnets and controlling traffic with security groups.Security:
IAM roles and policies are established to grant appropriate permissions to EKS resources. While network policies and security groups manage cluster access.Automation:
IaC tool, Terraform is used to define and manage EKS infrastructure, ensuring consistent deployments.3. Summary
By implementing an EKS infrastructure, Voyage Vista achieved a scalable, highly available, and secure platform for deploying their microservices based containerized application. The automation and monitoring capabilities provided by the infrastructure increased operational efficiency and reduced downtime, resulting in improved customer satisfaction and business growth.
