The document discusses how API management is evolving in the modern cloud native era with microservices and service meshes. It describes how decoupling applications into microservices and using service meshes to handle communication challenges impacts the role of API gateways. Specifically, API management involves more than just API gateways and requires solutions that separate the data plane from the control plane to adapt to changing architectures in a cloud native world. The document suggests patterns for cloud native API management that use microgateways and Envoy proxies combined with API management platforms.

❏ Decoupling applications from the infrastructure layer
can reduce costs, increase security and enable
innovation
❏ Container technology like K8S de-couples applications
from the compute fabric
❏ External APIs help decouple from external consumers
and producers
❏ Internal APIs help decouple from internal consumers
and producers
❏ Decoupling of apps into microservices
Application De-coupling leads to modernization

❏ Relieve developers from
doing the basic,
repetitive application
reliability work in a
distributed environment
❏ Resiliency, observability,
security, routing,

❏ Gateway acts as an
entry point to the
cluster
❏ Often decentralised,

platform team
❏ Envoy, K8S HA

❏ API Gateways are the runtime
Policy Enforcement Point of
API Management
❏ There is often a requirement to
de-couple the Management
and Runtime parts
❏ WSO2 Microgateway, Zuul
❏ Frameworks like Ballerina
API Gateway (Pattern)

❏ API Management often
involves more than just
implementing the Gateway
Pattern for services
❏ Features such as
❏ Managed APIs
❏ Rate limiting and throttling
❏ Monetization and Billing
❏ Analytics and Insights
❏ Developer ecosystem and
marketplace
❏ API Documentation and SDKs
❏ API lifecycle management
❏ API grouping/packaging
API Gateway != API Management

Not really. Not
