# Infrastructure provisioning
Provisioning a new datacenter or a pool of machines in a public cloud is a potentially long running operation with a lot of possibilities for intermittent failures. The scale is also a concern when tens or even hundreds of thousands of resources should be provisioned and configured. One useful feature for provisioning scenarios is Cadence support for routing activity execution to a specific process or host.
A lot of operations require some sort of locking to ensure that no more than one mutation is executed on a resource at a time. Cadence provides strong guarantees of uniqueness by business ID. This can be used to implement such locking behavior in a fault tolerant and scalable manner.
