The Functionless fantasy

In recent months, especially after the popular adoption of serverless, experts have been prophesying and urging the service providers to get to a state of Functionless. This is like the ‘Lambda Nirvana’; where you no longer hand code your functions and instead somehow knit the services using out of the box features to make things work the way we want them to work.

Though it sounds interesting and certainly a fantasy, the term Functionless, as the next evolutionary stage of Serverless, is far from being becoming a 100% reality. Similar to a natural evolutionary process, this will also take time before serverless as a technology matures and gets somewhat closer to being fully functionless.

Should that disappoint anyone? Absolutely not! Why, you may ask. Because, we have within our limited powers to…
