Effective Microservices Development with Ballerina - Anjana (40 min)

Ballerina is a network-distributed programming language, which is focused on bringing in the network awareness to programming. Ballerina has created higher-level abstractions for network services, endpoints, data security and more. Ballerina also follows sequence diagram based model in programming, where its programming constructs can be directly visualized as a detailed sequence diagram. This gives instant visibility on the design of your application, and self-documenting features. Ballerina also provides a rich concurrency mechanism based on a lightweight worker model, which optimizes the CPU resources in conjunction with nonblocking I/O operations. In this session, we will look at the basics of the Ballerina programs, and how to write microservices quickly, how automatic observability works in Ballerina, and also built-in deployment options such as Docker/Kubernetes/AWS Lambda.

API Management with Service Mesh - Lakmal (40 min)

Abstract: In a world of disaggregated API-based architectures, developers are increasingly adopting microservices — and Service Mesh is being used to control many service-to-service communications. But Service Mesh is not addressing the concern of how the exploding number of APIs can be exposed in a controlled and secure manner to their API consumers.

We'll discuss how to augment service mesh functionality w/ API management capabilities, so you can create an end-to-end solution for your entire business functionality — from microservices to APIs, to end-user applications.

Lunch will be provided along with a food truck, networking, giveaways and raffle prizes thereafter. Oh, the Beer is on us!. Register now as seats are going fast.
