Our customer had a complex requirement to move a broad set of legacy applications to a new web-based platform using CI/CD methodologies in order to support faster changes, better availability, and scalability.

Key Challenges :

• Large-scale legacy applications were being used globally to provide critical support for ~25M users.
• Current legacy systems were having problems with scalability and had long turn-around times for new application deployments.
• Maintenance windows were resulting in service interruption.

GOALS:

• Build a decentralized scalable design to deliver 99.95% application availability.
• Continuous Deployment by eliminating long maintenance windows that resulted in service interruption.
• Meet business transformation objectives like time-to-market.

Solution:

We worked alongside our client to gain a strong understanding of their applications. Through our partnership we:

• Deployed micro services covering 900 apps, and 4,100 APIs.
• Moved to integrated teams using DevOps and Agile workflows.
• Transitioned independent tools to integrated tools. For example, Rally was integrated with QA tools.
• Hosted multiple versions of software for different consumer types, managed by Cloud Foundry routing.
• Used Jenkins for continuous delivery of independent builds and deployments.
• Set up application availability monitoring tools.

Results:

Application scaling became nearly instantaneous and automated. What took months now takes minutes.
