Modern serverless technologies are coming in different sorts and ranges. But there is no doubt that it’s bringing significant innovation in the application development space. And today’s developer is trying to grasp the best approach for each cloud vendor. And often she faced with following questions
How do I start? Which platform supports my language of choice? How do I manage the application state? How do I integrate with existing «legacy» systems? In this presentation, Viktor Gamov will walk you through the setup and deploy a serverless application that includes event functions, services, data streaming. For event functions and services we will use the open-source Knative project on Kubernetes. For data streaming, we will use Apache Kafka.
The following code examples from the presentation can be tried out live.
