Businesses should outsource [almost] every non-core functionality to someone else
Unless it becomes so business-critical that it absolutely positively MUST be done in-house, go to a reliable vendor and pay them for their expertise
Programmers already* do this by using libraries when they write software (yeah, you learned how to build a graph data structure and implement a binary search tree in your second or third degree year, but you have never done it since - because the versions that exist in either language-supplied or community-based libraries are just plain better)
The days of "do it all yourself" are - blessedly - decades behind us now
Use the best* tools for the job, and worry about delivering your product/service to your customers
-----
* "best" may vary over time - cost, language, availability, etc are all factors in determining this for you
