CDN IMAGE RESIZE CODE

You can read more here for an Azure Functions Overview.

Functions scale up or down based on demand.

They support NuGet and NPM for external libraries, and provide a very easy way to leverage Azure services through triggers, which are ways to start execution of your code, and bindings, which are ways to simplify coding for input and output data.

You pay only for the time spent running your code.

You can choose between a variety of languages such as C#, F#, Node.js, Python, PHP, batch, bash, or any executable one.

You can write just the code you need for the problem at hand, without having to manage the infrastructure to run it. Serverless architectures: game-changer or a recycled fad?Īzure Functions is Microsoft Azure’s solution for running easily small pieces of code, or “functions,” in the cloud.

Serverless architectures by Martin Fowler.Reduced time to market / experimentationįor more info, I strongly encourage you to read the following posts:.Reduced packaging & deployment complexity.Reduced operational & development costs.Serverless Computing benefits can be summarized as follows: “Serverless can also mean applications where some amount of server-side logic is still written by the application developer but unlike traditional architectures is run in stateless compute containers that are event-triggered, ephemeral (may only last for one invocation), and fully managed by a 3rd party”.

What is Serverless Computing?Īs Martin Fowler states in his article about Serverless architectures: To do so, you need an Azure Blob Storage to store your images, and an Azure Functions app to write the few lines of code needed for this task to run.īefore we proceed, let’s start with the basics. Wouldn’t it be great if you could have a function which generates resized images from every new image that gets uploaded in your Azure blob storage, without having to create a new app and manage the infrastructure to run it? Welcome to the era of Serverless Computing where, through a few lines of code, you can have this function up and running in a few minutes.
