Serverless architectures have very much changed how modern applications are designed and built. They are the ultimate manifestation of the “use only what we need” mindset—we only pay for exactly the work that needs to get done, as opposed to having servers waiting around in case we have work to be done. Many organizations have reduced their costs by up to 90% through rearchitecting to a more cloud-native serverless model.

Of course, serverless architectures are not for every use case. Yes, there are still servers behind those serverless applications, but the great part is that we only need to concern ourselves with the ultimate task rather than all the supporting infrastructure. Generally, serverless options excel in situations where our workload can be broken down into small, discrete steps. That said, a decent portion of workloads can be broken down into smaller steps, which is why serverless architectures are so versatile.
