CLOUD-NATIVE :
PARADIGM TO BUILT APPS FOR
THE CLOUD!
Architecture Room Stuttgart 7
© OPITZ CONSULTING 2021 / Öffentlich
WHAT DOES CLOUD-NATIVE MEAN?
Architecture Room Stuttgart 8
¢ Apps follow the 12-factor app methodology for delivering software as a service (or product)
¢ Definition (published by Cloud Native Computing Foundation (CNCF)):
¢ Independent of deployment scenario:
¢ On-prem, hybrid or hybrid multi-cloud Source: https://pivotal.io/cloud-native
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.

¢ Bridges security trust domains (hybrid)
¢ Focus on exposing business functionality
Service Mesh
¢ Handles internal traffic
¢ Controls service-2-service communication
¢ Ensures internal trust between services
¢ Operates at the infrastructure level

¢ External Clients access an organization’s services
through the API Gateway (Single Point of entry)
¢ API Gateways are integrated in the Mesh
¢ Just another service from the Mesh’s perspective
¢ Also get own Service Mesh Proxy (SMP)
¢ Internal traffic routing is handeled by the Mesh
¢ Benefits:
¢ Consistent security
¢ Proper insights / Observability

KEY TAKEAWAYS
Architecture Room Stuttgart 37
¢ API Gateway and Service mesh can be combined (depending on the use case)
¢ Both Patterns help to increase developers efficiency
¢ Devs can focus on business code, while things like connectivity challenges are solved on an
infrastructure level (by a mesh)
¢ Central management
¢ BUT: Could also be seen critical by developers, since it also decreases a team’s autonomy!
¢ Using either API Gateway or Serivce mesh does not depend on the direction, but on the use
case (North-South vs. East-West)

Architecture Room Stuttgart 8 ¢ Apps follow the 12-factor app methodology for delivering software as a service (or product) ¢ Definition (published by Cloud Native Computing Foundation (CNCF)): ¢ Independent of deployment scenario: ¢ On-prem, hybrid or hybrid multi-cloud Source: https://pivotal.io/cloud-native 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.
