Microservices are oversold. CIOs jump on the bandwagon because they read a couple of articles on line and think magic happens. The last company, a spin off from a larger company in the financial sector, I worked for before retiremnent decided to port their existing monolith to a cloud-based, microservice platform. Did they need it? No. The total customer count was projected to be 25 million or fewer with an average active user count in the low 1000s, about 1800 when I left. But cloud/microservices were "sexier" to the ownership group whose plan was to sell it in a couple of years. Thus far they haven't succeeded and the microservice guru that succeeded me has been fired for failing to delivery a working product after three years. If a company isn't going to be operating at internet scale, e.g., NetFlix, Facebook, Amazon, there are usually better options than going all in on microservices. Then again, I've worked for companies that had no idea how many simultaneous users they had.
