Serverless, for the most part, is the promised land of software development. It cuts downtime to ship the product and significantly lowers the cost of implementation and usage of the system. It almost removes the need for any operational tasks and offers an unbeatable grade of availability, security, and scalability.
According to Gartner, more than 20% of global enterprises will have deployed serverless computing technologies by 2020, so this is the train you do not want to miss. Serverless is all about building an IT system using cloud-provided services and, if necessary, glueing them together with functions like Lambda. As a result, we get a solution that we don’t have to manage and we only pay for what we use.
#Serverless is the promised land of software development.
Serverless isn’t always a bed of roses. It has some pain points that you’d better get familiar with to prevent you from failing on your journey. Often, best practices that we have been using for decades for building our systems turn out to be antipatterns. That’s not a problem if you’re aware of conceptual differences. There are still some technical limitations you should be aware of when it comes to serverless, they’re gradually being mitigated as tech develops.
Let’s take a closer look at the obstacles you could encounter while building a serverless system; I’ve put this into context because the good parts vastly outweigh the bad.
