The source code you write as a developer is important, but it is only one part of the entire application that goes into production. To deploy an app, you’ll need resources like API gateways, S3 buckets, or VPCs as well. Configuring those resources is a task you don’t want to do manually. How about building your infrastructure as code using the same language you’ve built your app in. That is what Pulumi allows you to do!
As a trend cloud vendors tend to use the word serverless quite loosely. While serverless comes in a lot of shapes and sizes and as long as the characteristics fit within the four categories from my last blog, it is a serverless service. To make sure that we’re all on the same page, I’ll use the following definition for serverless:
“Serverless is a development model where developers focus on a single unit of work and can deploy to a platform that automatically scales, without developer intervention.”
In this blog post, we’ll look at how that model works on AWS Fargate, which allows you to run containers without having to manage servers or clusters.
There are many predictions from market analyst firms on the size of the global serverless architecture market and how fast it will grow. The numbers range from $18B to $21.99B in the next few years with the compound annual growth rate (CAGR) in the double digits. But is serverless only a fancy name for products like AWS Lambda and Azure Functions?
The CTO of a company I have worked for used to say that services should be loosely coupled but tightly integrated. I didn’t realize until a lot later how true that statement is as you’re building out microservices. How those microservices communicate with each other has also changed quite a bit. More often than not, they send messages using asynchronous protocols. As an industry, we decided that this new way of building apps should be called “Event-Driven Architecture (EDA).”
