Summary

This series of articles demystifies marketing myths and jargon for software product design and MVPs.

Here is the summary:

Introduction

No matter how much digital and abstraction we obtain, each digital product must be based on physical machines.

There are two main sides to any software product, the user interface (also called the Client) will run on machines that interact directly with people, for example a desktop internet browser, a smartphone, an augmented reality headset... etc.

On the other side are a lot of hidden programs and machinery that we want to hide from the user, what we call the Back-End. It generally works on computers "always connected to the Internet", called servers. Take time to observe the correlation between the server as a computer machine and the server as programs running on a machine.

The Cloud

A Cloud service is a service that is made available to users on demand via the Internet from the servers of a cloud provider and not from a company's local servers.

Cloud services are designed to provide easy and scalable access to applications, resources and services, and are fully managed by a cloud service provider such as Amazon Web Services, Microsoft Azure and Google Cloud Platform.

Almost all IT resources can live in the cloud: software program or application, service or complete infrastructure. For example, if a company wants to build an IT infrastructure, it is usually possible to install servers, software and network resources.

Infrastructures and Cloud

10 years ago, before the Software as a Service boom, each software company had to manage its own Bare Metal servers. This means allocating space in large noisy rooms and all the infrastructures involved: high bandwidth availability, redundancy hardware, switch cables, optical fibres...

During this period, many large technology companies have built complex server infrastructures internally (Google, Amazon, Microsoft...).

For example, Amazon saw the opportunity early on and started offering its Server as a Service infrastructure. This meant that you can now run your software on the same infrastructure of the server used by Amazon for a few cents a month.

Conclusion

Now, when you hear about the people from the “Cloud” and you keep wondering what mysterious technology it hides, remember that it simply means running your services on an external infrastructure that you don't own in exchange for a fee for the benefit of managing any physical infrastructure.
