Reuse has been a battle cry of developers since I was a lowly COBOL programmer back in the 1980s. Then we defined functions that could be called many times, and the structural programming age was born.
We then drifted to other languages such as C and the object-oriented C++ as better ways to build on the notion that reuse is good. Next we moved on to distributed objects and SOA (service-oriented architecture) services where reuse grew out of single applications, and then to reusable services that are loosely coupled and reside on different platforms. Now we have the notion of cloud services or APIs and the compelling concept of microservices providing a new granularity of sharing. Whew!
Reuse and/or sharing has taken on a new meaning for cloud and noncloud developers. Many are using the acronym DRY or “don’t repeat yourself,” as their new slogan for building and deploying applications and systems in 2022. However, it’s not as easy as that.
