What is custom code? To answer this question, let us begin with a metaphor. Imagine that code is a vehicle: a red Corvette Sports car for example.
You might say to yourself, “I want this red Corvette Sports car. So I will put the car together build the engine paint it install all the electronics and then get it entirely road-legal and become responsible for driving it and maintaining too.” That means if the car breaks down and it requires fixing then you will be solely responsible for fixing the issue or you would have to hire someone to take that responsibility on your behalf. This is the definition of custom code.
As you can see developing custom code is time-consuming and complicated to create maintain and change the key advantage is that it can be used to support any use case and also a point-to-point integration.
Custom code comes in many shapes and forms. Often, custom code is used to connect two systems together, thus known as point-to-point integration.
Therefore, this type of integration normally requires developers to build custom code between numerous applications, systems, data, and devices within the enterprise.
Point-to-point integration enables communication between data and further creates a one-to-one connections between data.
The only downfall or cons are that it is not future-proof and does not scale due to its “spaghetti architecture” that creates a system that is tangled, fragile and difficult to maintain long term.
