Rethinking Centralization
In general, my line of thinking here is this: some things work well when they’re distributed, others work well when they’re centralized. Our bodies have a “central nervous system,” which is tied to a single point of failure (the brain), though our brains turn out to have some redundancy. On the other hand, other systems in our bodies are distributed, such as our reaction to being cut (and bleeding to death). What we need to start doing is thinking through what works well where, and figuring out how to move each one to that specific destination.
Another parallel in this space is what we’re facing now in application development. We like to say that we’re moving towards the cloud — which means thin clients and thick servers. The reality is, though, services are being broken down into microservices and distributed, and a lot of the processing that takes place does so on the client side by code pushed there from the server. In other words, our belief that the cloud “centralizes everything” is an oversimplification.
Taking one step back, we can always build centralized systems that scale to today’s requirements — the challenge is that we don’t know what tomorrow’s Continue reading
