alt Hacker NewsI mean, microservices split the code into smaller chunks but now lots of little pieces communicate over the network and unless you are using some form of RPC, this communication channels are not typed and there's a lot more stuff that could go wrong (packets dropped, DNS not resolving). Plus you could update one microservice and not update its dependents. I think a lot of people jumped on the hype without realising that it's a trade-off
I work at a largish org (where microservices make sense but there are monoliths too) and the scary bits are unowned functionality. Leaning into a platform but being a business it isn't pure generic like say AWS it knows ahout the business. Some features are distributed across dozens of services. It is a skill hunting down who to blame for a problem. Not blame, ask for help, of course ;)
