And then they hit all the things that make sense in big company with like 40 services but very little in their context and complain that complex thing designed for complex interactions isn't simple
The database is more complex since there is storage affinity (I use cockroachDB with local persistent volumes for it) - but stateful is always complicated.
Personal projects are one thing, but even the smallest startup wants to be able to avoid data loss and downtime. If you are running everything on one server, how do you do kernel patches? You need to be able to move your workload to another server to reboot for that, even if you don’t want redundancy. Kubernetes does this for you. Bring in another node, drain one (which will start up new instances on the new node and shift traffic before bringing down the other instance, all automatically for you out of the box), and then reboot the old one.
Again, you could do all of this with other tech, but it is just standard with Kubernetes.
Seems true at a glance!
> and downtime.
Maybe less so - I think there’s plenty out there, where they’re not chasing nines and care more about building software instead of some HA setup. Probably solve that issue when you have enough customers to actually justify the engineering time. A few minutes of downtime every now and then isn’t the end of the world if it buys you operational simplicity.
Then I realized giving it root on a $3 VPS is functionally equivalent. If it blows it up, you just reset the VM.
It sounds bad but I can't see an actual difference.
