When you decide to adopt microservices, you are explicitly moving away from having just one or a few moving pieces to a more complex system. In this new world, the many moving parts act in unpredictable ways as teams and services are created, changed, and destroyed continuously. This system’s ability to change and adapt quickly can provide significant benefits for your organisation, but you need to make sure that some guard rails are in place or your delivery can come to a standstill amidst the neverending change.
These guardrails are the prerequisites we discuss here. It is possible to successfully adopt a new technology without some or all of these in place, but their presence is expected to increase the probability of success and reduce the noise and confusion during the migration process.
Admittedly, the list of prerequisites presented here is long and, depending on your organisation’s culture and infrastructure, might require a massive investment. This upfront cost should be expected, though.
