For a basic web application, it would take a lot of functions. That said, I donРІР‚в„ўt 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 arenРІР‚в„ўt 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.Р”В«oth 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.Р”Р‡unction-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 РІР‚СљcloudРІР‚Сњ 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 donРІР‚в„ўt necessarily have a server or control the resources they are running on, you canРІР‚в„ўt 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 ProvidersР”Р„WS, 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.

Scheduled tasks РІР‚вЂњ They are a perfect way to run a certain piece of code on a schedule.

Dynamic or burstable workloads РІР‚вЂњ If you only run something once a day or month, no need to pay for a server 24/7/365.

Super high volume transactions РІР‚вЂњ Isolate them and scale them.

We see a lot of value in isolating that logic to a function that we can scale. We have some transactions that happen hundreds of times per second. We have been looking to use them at Stackify primarily for our very high volume transactions.

Like most things, not every app is a good fit for FaaS. Return req.CreateResponse(HttpStatusCode.OK, 'Hello ' + data.name) Log.Info('C# HTTP trigger function processed a request.') Р”Вynamic data = await () Public static async Task Run(HttpRequestMessage req, TraceWriter log)

Shows how easy it is to process an HTTP request as a РІР‚СљFunctionРІР‚Сњ. Here is a simple example below from Azure Functions.

Services that are event-driven and instantaneously scalableР”Р„t the basic level, you could describe them as a way to run some code when a РІР‚СљthingРІР‚Сњ happens.

Billing based on consumption and executions, not server instance sizes.

Complete abstraction of servers away from the developer.

TheyР’В are expected to start within milliseconds and process individual requests and then the process ends.

Software developers can leverage this to deploy an individual РІР‚СљfunctionРІР‚Сњ, action, or piece of business logic.

What is Function-as-a-Service (FaaS)?Р”Р‡aaS 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.
