Top Disadvantages to Adopting Microservices (And Why You Should Do It Anyway)


New system architectures introduce brand new skills, tools and processes that need to be learned. The flow of data across new distributed systems is much more complex, especially within systems working at mass scale. Unfortunately, because the systems creating the logs are distributed, so are the logs. Containers are taking over the software world, changing the way and pace in which we design, write and deliver software.

That’s because of the way they are built, as the architecture of conventional, silicon-based computer hardware has data being sent between separate memory and processor units. Compare that with the architecture of the human brain, which stores and processes information within the same synapse (the junction between two neurons in the brain), resulting in a relatively more effective and low-energy operation.

An Interview


From there I moved to an engineering department in 3M where we developed control systems for the big machines that make tape. Every large agile framework that I know of is an excuse to avoid the difficult and challenging work of sorting out the organization’s system architecture so that small agile teams can work independently. For example, the dependencies generated by the big back end of a banking system is a huge source of friction for product teams.
