This is nothing new, Azure has been having capacity problem for over a year now[1]. Germany is not the only region affected at all, it's the case for a number of instance types in some of their larger US regions as well. In the meantime you can still commit to reserved instances, there is just not a guarantee of getting those instances when you need them.
The biggest advice I can give is 1. keep trying and grabbing capacity continuously, then run with more than what you need. 2. Explore migrating to another Azure region that runs less constrained. You mention a new region would be complicated, but it is likely much easier than another cloud.

- alexeldeib 4y agoRI are a billing concept (discounted rates for long term commitment). Dedicated capacity exists, but it’s different (compute reservation groups or dedicated hosts). You can combine CRG/DH with RI for the desired effect, although IMO it’s a bit confusing. (Azure employee)
- robertlagrant 4y agoIt's a billing mechanism. You pay less if you guarantee use. Sadly, they don't guarantee availability of things to use :)
- rsynnott 4y agoYup, I'm aware of reserved instances (from an AWS PoV) but I always assumed they were, at least theoretically, well, reserved!
- count 4y agoIn the AWS context, they are, in fact. That's the original point of them - so during big AZ failures your reserved instances had first dibs on the available capacity. The billing thing became more of the point as big AZ failures are so rare.
- vageli 4y agoNon-zonal instance reservations do not reserve capacity. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-capacity-reservations.html#capacity-reservations-differences https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-capa...
- count 4y agoWell, yeah. But the zonal ones still do.
- aeyes 4y agoOn AWS instances are only reserved if you reserve a specific instance type in a specific zone. Reservations across multiple zones or savings plans don't reserve capacity.
- sgerenser 4y agoReminds me of the classic Seinfeld car reservation bit: https://m.youtube.com/watch?v=4T2GmGSNvaM https://m.youtube.com/watch?v=4T2GmGSNvaM
- alexeldeib 4y agoGreat bit! Same with airline overbooking ;)
- lr1970 4y agoWith dedicated tenancy AWS Reserved Instances are physically reserved for you.
