![]() Traditional architecture therefore focuses on the resilience and performance of a relatively small fixed number of components. Traditional architecture tends to optimize for a fixed, high-cost infrastructure, which requires considerable manual effort to modify. cloud-native architecture, focuses on how to optimize system architectures for the unique capabilities of the cloud. Principles for cloud-native architectureThe principle of architecting for the cloud, a.k.a. In this post we set out five principles of cloud-native architecture that will help to ensure your designs take full advantage of the cloud while avoiding the pitfalls of shoe-horning old approaches into a new platform. For instance, provisioning a replacement server can take weeks in traditional environments, whereas in the cloud, it takes seconds-your application architecture needs to take that into account. However, some of the fundamental assumptions about how that fabric performs change when you’re in the cloud. This means that almost all of the principles of good architectural design still apply for cloud-native architecture. The good news is that cloud is made of the same fabric of servers, disks and networks that makes up traditional infrastructure. A well-architected cloud native system, on the other hand, should be largely self-healing, cost efficient, and easily updated and maintained through Continuous Integration/Continuous Delivery (CI/CD). ![]() If architects fail to adapt their approach to these different constraints, the systems they architect are often fragile, expensive, and hard to maintain. While the functional aspects don't change too much, the cloud offers, and sometimes requires, very different ways to meet non-functional requirements, and imposes very different architectural constraints. 'orders must be updated on our existing mainframe system').
