@hguerreroo 14 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

@hguerreroo 15 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

@hguerreroo DATA 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

“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.” DATA GATEWAYS 21 Source: https://www.infoq.com/articles/data-gateways-cloud-native/
