Learning the Computer Basics Will Make You a Better Cloud Software Engineer

It is surprising to me that every day I meet developers who do not have a basic understanding of how computers work. Recently I got into an argument of whether this is necessary to become a good cloud software engineer, and the main point of my opponent was that “modern languages and frameworks take care of lots of stuff behind the scenes, hence you don’t need to know about those”. Although the latter is true, it does not release us (the people who develop software) from the responsibility to think when we write software.

The best analogy I can think of is the recent stories with Tesla’s autopilot – because it is called “autopilot” doesn’t mean that it will not run you into a wall. Similar to the Tesla’s driver, as a software engineer, it is your responsibility to understand how your code is executed (ie where your car is taking you), and if you don’t have a basic understanding how computers work (ie how to drive a car or common sense in general:)), you will not know whether it runs well.

If you want to become an advanced Cloud Software Engineer, there are certain things that you need to understand in order to be able to develop applications that run on multiple machines in parallel, across many geographical regions, using third party services and so on. Here is an initial list of things that, I believe, is essential for Cloud Software Engineers to know.

First of all, every Software Engineer (Cloud, Web, Desktop, Mobile etc.), needs to understand the fundamentals of computing. Things like numeric systems and character encoding, bits and bytes are essential knowledge for Software Engineers. Also, you need to understand how operating on bits and bytes is different from operating on decimal digits, and what issues you can face.

Understanding the computer hardware is also important for you as a Software Engineer. In the ages of virtualization, one would say that this is nonsense but knowing that data is fetched from the permanent storage and stored in the operating memory before your application can process it may be quite important for data-heavy applications. Also, this will help you decide what size virtual machine you need – one with more CPU, more memory, more local storage or all of the above.

Basic knowledge of Operating Systems, and particularly processes, execution threads, and environment settings are another thing that Software Engineers must learn, else how would you be able to implement or configure an application that supports multiple concurrent users.

Networking basics like IP addresses, Domain Name Service (DNS), routing and load balancing are used every day in the cloud. Not knowing those terms and how they work is quite often the reason web sites and services go down.

Last, but now least security is very important in order to protect your users from malicious activities. Things like encryption and certificate management are must-know for Software Engineers developing cloud-based applications.

You don’t need to be an expert in the topics above, in order to be a good Cloud Software Engineer, but you need to be able to understand how each of the topics above impacts your application, and tweak your code accordingly. In the next few posts, I will go over the minimum knowledge that you must obtain in order to have a solid background as Cloud Software Engineer. For more in-depth information you can research each one of the topics using your favorite search engine.
