First, let’s have a quick look as to how software was traditionally built.
Web applications are deployed on web servers running on physical machines.
As a software developer, you needed to to be aware of the intricacies of the server that runs your software.
To get your application running on the server, you had to spend hours downloading, compiling, installing, configuring, and connecting all sorts of components. The OS of your machines need to be constantly upgraded and patched for security vulnerabilities. For servers to run well at high load they must also be provisioned, load-balanced, configured, patched, and maintained.
In short, managing servers is a time-consuming task which often requires dedicated and experienced systems operations personnel.
The central task of education is to implant a will and a facility for learning; it should produce not learned but learning people. The truly human society is a learning society, where grandparents, parents, and children are students together.
In a time of drastic change it is the learners who inherit the future. The learned usually find themselves equipped to live in a world that no longer exists.
In our pursuits we should aim to be a learner, not learned.
Software today is becoming increasingly interconnected.
Instead of building things from scratch, an increasing amount of engineering work today is ‘connecting’ prefabricated parts together. We can rely more and more on third party services: businesses that expose an API - a software interface - that other systems connect to and use for services like payments, email, etc.
