Application Migration to AWS Cloud for Continuous Integration
Application Migration to AWS Cloud for Continuous Integration
Introduction
This case study focuses on the migration of a suite of Tomcat-based applications for continuous integration from an in-house infrastructure to the AWS Cloud. The applications involved in the migration included Jira, Confluence, Bitbucket, Jenkins, and Perforce. The objective was to evaluate performance, network, security, and disaster recovery considerations before migrating to AWS Cloud.
Problem
The existing infrastructure required modernization to enhance scalability, reliability, and flexibility. The in-house environment had limitations in terms of resource availability, and the organization needed a more robust and scalable solution for their continuous integration workflow. They aimed to leverage the benefits of the AWS Cloud to meet their evolving business needs.
Solution
To address the problem at hand, the organization collaborated with People Tech to execute the migration project. The solution involved the following steps:
Evaluation: Thorough evaluation of performance, network, security, and disaster recovery considerations in the context of the AWS Cloud environment.
Migration: Migrating the applications to AWS Cloud infrastructure after considering the evaluation results. This step involved provisioning, maintaining, and improving the existing cloud infrastructure to meet the organization’s requirements.
Development: Researching, designing, developing, and modifying enterprise-wide systems and applications software to ensure compatibility and optimal performance in the AWS Cloud environment.
Technology Used
The following AWS services were utilized in the migration project:
Route 53: DNS resolution for various applications, ensuring efficient communication between the applications and their respective endpoints.
EC2: Multiple Linux instances were utilized to host Jira, Confluence, Bitbucket, Jenkins, and Perforce, enabling continuous integration processes in the AWS Cloud.
Site-to-Site VPN: Implemented to establish private connectivity from the on-premises infrastructure to the AWS Virtual Private Cloud (VPC), ensuring secure communication.
Cross-Region Backup of EC2: To ensure business continuity in the event of a failure up to the regional level, all cloud servers were backed up cross-regionally.
RDS: SQL Server backend for the Fisheye application, providing a reliable and scalable database solution in the AWS Cloud.
Results
The migration to AWS Cloud provided the organization with numerous benefits. The scalability and flexibility of the AWS infrastructure improved the performance of the continuous integration workflow. The utilization of AWS services ensured robust security measures and disaster recovery capabilities. The organization experienced enhanced reliability and availability of the applications, leading to increased productivity and streamlined development processes.
Conclusion
The successful migration of the suite of Tomcat-based applications from in-house infrastructure to the AWS Cloud demonstrated the effectiveness of leveraging cloud computing for continuous integration. The organization achieved improved scalability, reliability, and flexibility by evaluating performance, network, security, and disaster recovery considerations and utilizing various AWS services. This case study highlights the importance of adopting cloud solutions to enhance continuous integration practices and underscores the benefits organizations can achieve by embracing cloud technologies.
