Moving your project to a cloud might be a difficult task especially since there are so many different cloud services out there. AWS is the most popular one and Azure is a very close competitor. In this article I will show you how to start using Azure, namely its NoSQL database service - DocDB. NOTE: Azure is a great platform, however it has significantly less tutorials and examples available online (compared to AWS). Before we start to write the code we will need to prepare the dependencies.

In this tutorial, we'll create a simple date of birth dropdown menu.

In my previous article I showed a tutorial on "Uploading data to Amazon S3 from Node.js". This is a good fist step to move your project to a cloud, but there's another important aspect that you have to consider. Your data. Luckily Amazon offers a range of services that supports the needs of many kinds of applications.

What can be simpler than uploading file to the server and saving it to hard drive, right? Open read stream, read bytes, open write stream, write bytes, done. Now let's explore the same question but from a high-load high-availability service perspective. You're designing new Instagram, where will you store the photos? Remember, at a bare minimum you need to make sure that a failure to a single node in a data center will not interrupt your service (you can't allow to lose those precious cat pictures that your users are uploading).
