This is a big difference from a traditional n-tier application (or monolith). Combined with robust automation, they allow engineers to make high-impact changes frequently and predictably with minimal toil.”įor example, look at this diagram below of a sample web-native architecture:
These techniques enable loosely coupled systems that are resilient, manageable, and observable. Containers, service meshes, microservices, immutable infrastructure, and declarative APIs exemplify this approach. “Cloud-native technologies empower organizations to build and run scalable applications in modern, dynamic environments such as public, private, and hybrid clouds.
At Microsoft, we’ve followed the definition set by the Cloud-Native Computing Foundation (CNCF): Things simply cannot go on this way.Įnter the world of the cloud native application. This system cannot go down – the business depends on it – but change is becoming near impossible, and highly risky. The framework – which is impossible to modernize with newer libraries – ages and becomes increasingly unstable. Deployments happen slower and slower, often quarterly, with frequent “red” builds and all-weekend build parties in corporate war rooms. Each change comes with unintended and costly side effects – new features are increasingly expensive to implement, and often breaks important pieces elsewhere. It all started out so easy – but as its functionality has expanded, so has the complexity, to the point where no one understands it well. The book begins with a description of the “Fear Cycle” that may be all too familiar – the life of someone in charge of a brittle, hard to maintain application. I encourage you to check out the podcast – and then dive deeper into Robert’s book for more! There’s also extensive coverage of many of these principles in my book “ Achieving DevOps ”, which Robert was instrumental in helping me launch. I’m sure you will too!Ī condensed version of our interview is below. I found our conversation enlightening – Robert’s always so locked into the realities of both legacy code and the real-world strengths and liabilities that come with developing and supporting enterprise software. NET Apps for Azure” which is available now in a preview version. Robert’s in the process of writing a great book on “Architecting Cloud-Native.
I had the pleasure recently of interviewing Robert Vettor, a Premier Developer consultant who specializes in microservices and cloud native architecture.
