Scaleway Placement Groups API is one of 74 APIs that [Scaleway](https://apis.io/providers/scaleway/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Placement Groups. The published artifact set on APIs.io includes an OpenAPI specification and API documentation.

Placement groups allow the user to express a preference regarding the physical position of a group of Instances. The feature lets the user choose to either group Instances on the same physical hardware for best network throughput and low latency or to spread Instances across physically distanced hardware to reduce the risk of physical failure. The operating mode is selected by a `policy_type`. Two policy types are available: - `low_latency` will group Instances on the same hypervisors - `max_availability` will spread Instances across physically distanced hypervisors The `policy_type` is set to `max_availability` by default. For each policy types, one of the two `policy_mode` may be selected: - `optional` will start your Instances even if the constraint is not respected - `enforced` guarantees that if the Instance starts, the constraint is respected The `policy_mode` is set by default to `optional`.
