DATA GATEWAYS
Microservices Data
● Independent database per microservice
○ Independent database instance
○ Independent schema and logical grouping of
tables
● Only one microservice owns the data
● Polyglot persistence layer

“A data gateway is like an API
gateway, but it understands and
acts on the data layer
implementation rather than the
networking layer”

DATA GATEWAYS
Data Gateway Capabilities
● Abstraction / Decoupling
○ Hides implementation
○ Abstracts physical source
● Security
○ Access control based on data model (row, column, etc.)
● Scaling
○ Caching and materialized views
● Federation
● Schema-first based on SQL standard

15. @hguerreroo

DATA GATEWAYS
Many Types of Data Gateways
● Classic Data Virtualization
● Database with Federation
● GraphQL bridges
● Cloud-hosted
● Secure tunneling data-proxies
● Open source data gateways

16. @hguerrerooDATA GATEWAY
Virtual Application Network
● An abstraction layer between the network and the application
services / processes
● Applications don’t need to be modified
○ HTTP/REST
○ gRPC
○ Messaging
○ General TCP/UDP (JDBC, etc.)
● A natural fit into container platforms: Kubernetes /Docker
● Application topology independent from network topology

21. “Data has gravity, requires granular access control, is hard
to scale, and difficult to move on/off/between
cloud-native infrastructures. Having a data gateway
component as part of the cloud-native tooling arsenal,
which is hybrid and works on multiple cloud providers,
supports different use cases is becoming a necessity.”
