For a basic web application, it would take a lot of functions. That said, I don’t see FaaS as being a complete replacement for normal application architectures. The idea of serverless architectures is a panacea for developers. Netflix uses AWS Lambda to help manage their AWS infrastructure with event-based systems. If you aren’t too sure if you are ready to take the plunge into FaaS, maybe a case study will help! It starts the function within a few milliseconds and then shuts it down.īoth provide the ability to easily deploy an application and scale it, without having to provision or configure servers.
With FaaS, it may not be running at all until the function needs to be executed. When deployed as PaaS, an application is typically running on at least one server at all times. Although, some providers, like Azure, also allow you to dedicate resources to a Function App. FaaS is designed to potentially be a serverless architecture. They handle provisioning servers and deploying your application to the servers.įunction-as-a-Service (FaaS) provides the ability to deploy what is essentially a single function, or part of an application. PaaS offerings like Azure App Services, AWS Elastic Beanstalk, and others, make it easy to deploy an entire application. Most PaaS hosting options can even auto-scale the number of servers to handle workloads and save you money during times of low usage.

It allows us to deploy our app and the “cloud” worries about how to deploy the servers to run it. Platform-as-a-Service greatly simplifies deploying applications. How we monitor these new types of apps is going to continue to evolve.

Since you don’t necessarily have a server or control the resources they are running on, you can’t install any monitoring software. You still need to understand how often they occur, how long they take, and potentially, why they are slow. One of the big challenges is monitoring your function apps. Read our article on how AWS, Azure, and Google Cloud compare to determine which cloud best meets your needs. A lot of innovation is still going on in this area and things are rapidly improving and changing. FaaS ProvidersĪWS, Microsoft Azure, and Google Cloud all provide a solution. For example, a web request could write to a queue, which is then picked up by a different function. These functions could also be chained together. Support and implementation for them varies by provider. Below is a simple list of some common scenarios. There are a lot of potential uses for functions.

Software developers can leverage this to deploy an individual “function”, action, or piece of business logic. What is Function-as-a-Service (FaaS)?įaaS is the concept of serverless computing via serverless architectures. How we deploy our apps continues to evolve thanks to cloud hosting, Platform-as-a-Service (PaaS), and now Function-as-a-Service.
It has never been a better time to be a developer! Thanks to cloud computing, deploying our applications is much easier than it used to be.
