Decisions made at the beginning of building a technical product have an impact on its future scale, delivery velocity, and the way to build new services. This session explores modern architectures, while focusing on containers technology, to guide teams in making the right choices. It also examines how you can design your organization and your technology for constant change. We’ll discuss which technology choices are crucial to getting started and, more importantly, which choices can be deferred to a later stage as the project scales and evolves. Combined with DevOps and Platform engineering practices, we will discuss what needs to be done to enhance developer productivity. Drawing on insights from our past experience working with a wide range of customers, we will explore the journey of projects, from initial technology decisions to scaling challenges, and share key lessons with examples.
