After conducting a comprehensive analysis of the challenge faced by PhoneBurner in maintaining uptime during software updates, DoiT came to the conclusion that a Blue/Green deployment strategy would be the most appropriate approach. To do so, the PhoneBurner team need to plan on the deployment of new servers with the updated version of the application (known as “Green”) alongside the existing servers running the older version (known as “Blue”). Through this approach, traffic is gradually diverted to the new servers as they are tested and proven stable and reliable.

DoiT created specific customized solutions to tackle the challenges related to implementing the Blue/Green approach, which included the unique limitations of PhoneBurner’s application and the inadequacy of available ECS strategies. To optimize the use of ECS and Jenkins, the DoiT CREs developed a customized solution using Terraform and Jenkins pipelines to overcome this blockers and facilitate the Blue/Green deployment strategy.

In parallel, the team also implemented automated testing of the Green environment to ensure it was functioning correctly before diverting traffic. They also integrated this testing process into the existing deployment pipeline to seamlessly orchestrate traffic diversion to the new servers.

Through implementing this customized solution, PhoneBurner could successfully deploy software updates without compromising the availability of their platform. The Blue/Green deployment strategy and automated testing process provided a reliable and efficient solution for maintaining uptime during updates.
