So many gems in here but this one about microservices is my favorite:

- Cannot be run without an orchestrator like K8S, which is a bear to install and maintain, which helps sell managed cloud.
- Uses more network bandwidth, which they bill for, and CPU, which they bill for.
- Makes it hard to share and maintain complex or large state within the application, encouraging the use of more managed database and event queue services as a substitute, which they bill for. (Example: a monolith can use a queue or a channel, while for microservices you’re going to want Kafka or some other beast.)
- Can’t be run locally easily, meaning you need dev environments in cloud, which means more cloud costs. You might even need multiple dev and test environments. That’s even more cloud cost.
- Tends to become dependent on the peculiarities of a given cloud host, such as how they do networking, increasing cloud lock in.
Anyone else remember how cloud was pitched as saving money on IT? That was hilarious. Knew it was BS way back in the 2000s and that it would eventually end up making everything cost more.
