don’t live in just 1 place • App components and infrastructure can be spread across: • Cloud providers • Regions and zones • Clusters • Justifications • Availability • Resiliency • Cost • Unique services
for - act with intention • Understand the infrastructure needs of your app • Tool explosion • how many dashboards, GUIs, consoles do you want to live in? • how many skills sets do you need to learn or hire for? • Monitoring, management, policy, operations...
and orchestration decisions for the entire solution • Centralizes decision making into an authoritative place • Single entry point API • Kubernetes has a control plane • schedules pods/resources across nodes • Global control plane is similar - but bigger scope • Provision infrastructure needed by app • Deploy application components to clouds, regions, etc.
applications and their infrastructure • Based on Kubernetes control plane • Provision infrastructure declaratively using the K8s API • Publish your own declarative infrastructure API without code • self-service, on-demand, policy, config, best practices • Run and deploy applications alongside infrastructure • The OAM implementation for Kubernetes
etc. • Control plane API - centralized place for provisioning & consuming infrastructure • Define the right API for your organization • Abstractions to • hide complexity & environment knowledge • codify policy & best practices • enable self-service by apps Consuming Infrastructure
