Exactly this. You don't go to containerization because it's cheaper / more efficient, you go to it because it's more flexible and lets you simplify your tech ops into business ops faster. Containers require a LOT of infrastructure / overhead to build -- and don't be seduced by cloud providers that abstract that complexity, if you build a business on containers you WILL have to deal with it. But it does allow you to de-skill a lot of tech ops processes, which helps reliability (so long as your strategies are effective). And you're right; depending on the way they handle their sharding (which may be part of a greater data availability strategy) this might not be so bad. But business goals are driving this, so you have to find a way to make the tech deliver what the business wants.
