OKR template to successfully transition from monolith to microservices architecture

This OKR focuses on successfully transitioning from a monolithic model to a microservices architecture. The transition begins with the setting up of the new structure in a test environment, ensuring that it maintains a 98% uptime. Any issues that result in downtime are noted, resolved, and then monitored to maintain uptime standards.

Next, it looks at the creation of a concrete migration plan. This plan needs to be fully fleshed out within four weeks, detailing every step of the transition, including the resources and timeline required. It should comprehend everything from the smallest services to the most complex apps that need migration.

The final part of this OKR tackles the actual migration of application modules into their new microservices architecture. The goal is to successfully transfer a total of 75% of these modules. Priority for those modules which are migrated first, is dictated by both their business need and the dependencies they have on one another - to ensure a smooth transition process.

Overall, this OKR is geared towards facilitating a smooth and thorough transition from a monolithic model to a robust and efficient microservices architecture. Through diligent observation, planning, and execution, the model's significant transition is expected to deliver great results with minimal disruption.
