Private cloud without vendor lock
Serverless aka FaaS is a true cloud approach, scalable and promising. But it has multiple well known problems. Some of them have partial solutions, like websockets and stateless but vendor lock stays a most important problem we have in serverless approach as of today. So we will discuss key reasons and origins of this problem and will find a way to reduce its impact. Also we will discuss all other problems and uncover relations to the main one. We will use Node.js and JavaScript just as an example technology stack but ours findings will be generalized and relevant for other technologies.
