Challenge

Being a financial institution with a large market capitalization, the design and architecture of the DevOps setup needed to be scalable with high availability for onboarding future applications that needed to be hosted on premise. With no prior setup in place, all activities had to begin from scratch right from license procurement to hardware configuration. Banking processes, such as Service Desk Integration, Release Notes Integration, Security Vault Integration, Security Communication requirements, etc. needed to be adhered to. There was no coordination and streamlining of processes between internal and external teams, and the project needed several other customized requirements that had to be addressed innovatively.

Solution

The implementation of DevOps by Wipro enabled the client to integrate its various disconnected processes and teams, both internal and external, to achieve deployment automation.

The scope of the engagement included the following activities:

• Deployment of enterprise versions for Cloudbees Jenkins, JFrog Artifactory, SonarQube and Ansible Tower for high availability and scalability of respective applications
• Creation of custom pipelines in Jenkins and workflows in Ansible Tower to target deployments
• Creation of different folder hierarchies in Artifactory to manage different branches and their respective versions
• Creation of database pipeline to execute DB scripts with integration of application quality and security profiles
• Generation of post-deployment reports to be sent to the respective teams, with success/failure emails of pipelines triggered to the concerned teams along with creation of rollback pipeline
• Implementation of the blue-green deployment strategy to minimize downtime and risk
• Integration of security vaults to ensure non-sharing of production passwords
• Integration of webhook with GitHub
• Functional test automation using Selenium and UI Path, and integration with CI/CD pipeline

Business Impact

Wipro’s solution enabled the client to streamline its processes and teams, design and build a robust DevOps setup, and address custom requirements specific to the client. The bank now has a central- ized deployment system that is scalable and reliable, resulting in the following benefits:

• Over 70% savings in time taken for various SDLC processes across multiple teams by automating the entire process of code commit to deployment. For instance, the process of delivering a new code change to UAT build has now reduced drastically from 7 working days to under 30 minutes
• 50% reduction in failure rate of deployment
• Applications teams can now download the back dated binaries from a centralized Artifactory repository, providing cost benefits of drive requirement for each application with centralized backup and retention policies
• Automated QA ensured a high level of quality of business services deployed. All checks are now completed by the system, ensuring build quality and security
• Smooth switchover to deployment by migrating from the outdated Concurrent Versions System (CVS) source code repository to GitHub
• Test cases are now triggered in an automated manner and project teams can view the generated reports
