In the recent past, there has been tremendous advancement in cloud computing, which has led to more and more services being provided over the internet. A classic example of this is the music industry. Earlier users had to store songs and music videos on their laptops, but now they are able to stream the same songs over the internet. The growth in the usage of cloud services only means that going forward it would be imperative for a developer to be able to build services that leverage the cloud infrastructure. In this chapter, we will look at how we can build a computer vision service that can take in an input from a user over the internet, process the image, and send the result back to the user in no time.
