When service mesh was introduced as a concept, some thought this was the end of APIs - a few even said: "API Management is Dead". However, it was fiction, and the reality is that APIs are a crucial attribute of modern digital enterprises. Mesh architecture is fueling distributed patterns like microservices and Web 3.0. As a result, sub-patterns such as data, event, and identity mesh are added to the catalog. At the same time, mesh implementations are improving by utilizing high-performance low-level protocols like eBPF. In this session, Asanka will deep-dive into the mesh architecture and look at the role of APIs from a digital craftsman's view.

18. Cell-based Architecture
● Introduced in summer-2018
● A decentralized reference architecture
for cloud-native applications
● Cells are the units of a composable
enterprise
⦿ Self-contained
⦿ Deployable as a unit
⦿ API centric - inter and intra cell
communication
● Represents domains/subdomains in
Domain-driven Design (DDD) & team
boundaries in agile development

21. Summary
Service Mesh and APIs are supporting not competing technologies
Combination of both technologies streamline the communication
APIs are the products of 21st century, need an API supply chain & full LCM
Service, Data, Event, Identity mesh
Improving with language, infrastructure and implementation (eBPF)
Fueling the future - Web 3.0, metaverse…..
