Harder, Better, FaaS’er, Stronger: A Serverless Workshop @ in5 Tech


September 25, 2019

Serverless computing refers to a model where the existence of servers is entirely abstracted away. Even though servers exist, developers are relieved from the need to care about their operation. They are relieved from the need to worry about low-level infrastructural and operational details such as scalability, high-availability, infrastructure-security, and other details. Serverless computing is essentially about reducing maintenance efforts to allow developers to quickly focus on developing code that adds value.

Serverless computing simplifies developing cloud-native applications, especially microservice-oriented solutions that decompose complex applications into small and independent modules that can be easily exchanged.

Serverless computing does not refer to a specific technology. Instead, it refers to the concepts underlying the previously described model. Some promising solutions like Apache OpenWhisk have recently emerged that ease development approaches used in the serverless model.

IBM Cloud Functions is a Function-as-a-Service (FaaS) platform on IBM Cloud, built using the Apache OpenWhisk open source project, that allows you to execute code in response to an event.

It provides a serverless deployment and operations model. With a granular pricing model that works at any scale, you get exactly the resources you need – not more, not less – and you are charged for code that is really running. The flexible programming model includes support for languages like JavaScript, Swift, Python, and Java and support for running custom logic through Docker containers. This programming model allows small agile teams to reuse existing skills and to develop in a fit-for-purpose fashion. IBM Cloud Functions also inlucdes tools to declaratively chain together the building blocks you develop. You can chain microservices to form workflows through composition. It is open and can run anywhere to avoid any kind of vendor lock-in.
