Migration of Java Enterprise Application to Kubernetes

About the client:

Our customer is a US-based Organization working in the knowledge management industry. The client has planned to migrate Java enterprise applications to Kubernetes.

Requirement:

The requirement was to Deploy Java enterprise document management and business process management system on the Kubernetes cluster. This involves customizing the Helm charts, KOPS, KubeCtl, AWS EKS, EC2, ELB, S3, Route53.

Challenges:

The clients are working in the content management area and need to process a huge number of
documents. As they deal with huge content and they needed the production-grade orchestration solution.

Following were some of the challenges the client faced :

• Inefficient to handle the load
• Difficult to deploy changes.
• Deployment with zero downtime
• Difficult to manage servers

Our Solution:

Kubernetes (K8s in short) is an open-source container orchestration platform. We have deployed the existing system on the Kubernetes cluster build on AWS.

We have converted the existing architecture into microservice architecture by modularising the services. Each microservice of the system was independent and stateless. This lead to the fault-tolerant system.

We used the containerization approach to deploy the services which lead to an easier and efficient approach for the deployment.

With the help of the Kubernetes dashboard client can monitor the container and services.

Business Benefits:

Our solution has successfully migrated the application to Kubernetes which has given the client the production-grade orchestration solution. The following are the benefits:

• Highly available and fault-tolerant
• One-click deployment
• Zero downtime
• Managing and monitoring of the server with ease
