Azures blob service supports the first one. Its strongly consistent and has a lease/lock API. Ive seen leader election and coordination stuff built on top of it.

Why the id generator? Aren't GUID's enough? The chance of a collision is basically 0.

For most of the use cases GUID works great. There are some cases where we need a numerical id which is sequential.
