Entering the next level - Migrating to cloud native platforms

Organizations are moving from centralized data centers to distributed cloud native platforms. Due to the complexity of such a migration, the organization will be running a hybrid multi-platform environment which spans from the old to the new world. It starts at the edge of a system, using functionality provided by an API Gateway or Platform.

3. Initial situation Modernize IT 3
4. Reasons for modernization 4
5. Reasons for modernization faster deployments 4
6. Reasons for modernization faster deployments some components need to update more frequently than others 4
7. Reasons for modernization faster deployments some components need to update more frequently than others some components need different scale requirements 4
8. Reasons for modernization faster deployments some components need to update more frequently than others some components need different scale requirements some components should be developed in a different technology 4
9. Reasons for modernization faster deployments some components need to update more frequently than others some components need different scale requirements some components should be developed in a different technology codebase is too big and complex 4
10. Cloud Native CNCF Definition, https://github.com/cncf/toc/blob/main/DEFINITION.md "Cloud native technologies empower organizations to build and run scalable applications in modern, dynamic environments such as public, private, and hybrid clouds. Containers, service meshes, microservices, immutable infrastructure, and declarative APIs exemplify this approach. These techniques enable loosely coupled systems that are resilient, manageable, and observable. Combined with robust automation, they allow engineers to make high-impact changes frequently and predictably with minimal toil." 5
11. Integration Patterns 7
12. File Transfer 8
13. Messaging 9
14. APIs 10
15. "Business logic shouldn’t be implemented within the integration technology layer" 11
16. API first 13
17. API first An API is the first (and often only) interface to users of an application 13
18. API first An API is the first (and often only) interface to users of an application An API comes first — before the implementation 13
19. API first An API is the first (and often only) interface to users of an application An API comes first — before the implementation An API is described (documented) or self-descriptive 13
