User defined logical spread placement groups for computing resources within a computing environment

A system, comprising:

• one or more processors;
• and
• memory that stores computer-executable instructions that, as a result of being executed, cause the system to:
• receive, by a service of a computing resource service provider, a request to launch a compute instance within a first set of logical partitions in a computing environment operated by an entity of a plurality of entities, the request generated based at least in part on a set of interactions from an interface of a device associated with the entity indicating a diversity constraint identifying at least one type of hardware-based placement condition for placing a first set of server computer systems participating in the first set of logical partitions and a second set of server computer systems participating in a second set of logical partitions, a number of the first set of logical partitions that are associated with the entity, and a placement strategy associated with the entity, the placement strategy corresponding to a placement algorithm of a plurality of placement algorithms available for selection including at least even distribution and clustered distribution;
• select, by the service, a server computer system based at least in part on the placement strategy associated with the entity, the diversity constraint, and placement information obtained from a database that indicates a set of other compute instances associated with the entity in the first set of logical partitions, where at least one other entity of the plurality of entities is associated with the second set of logical partitions;
• cause, by the service, the server computer system to launch the compute instance on the server computer system based at least in part on the placement algorithm and the diversity constraint;
• and
• update the database based at least in part on the placement information to indicate that the server computer system is associated with a logical partition of the first set of logical partitions.

A non-transitory computer-readable storage medium having stored thereon executable instructions that, as a result of being executed by one or more processors of a computer system, cause the computer system to at least:

• obtain a request generated based at least in part on an interaction with an interface from a device associated with an entity, the request indicating a set of logical partitions of a computing environment for placement of a compute instance, a diversity constraint, and a placement strategy defining placement of compute instances among the set of logical partitions, where the diversity constraint comprises even distribution or clustered distribution;
• determine to launch the compute instance within the set of logical partitions in the computing environment associated with the entity associated with the request;
• select, by a service of a computing resource service provider, a server computer system based at least in part on the placement strategy associated with the entity and placement information obtained from a database that indicates a set of other compute instances associated with the entity in the set of logical partitions implemented by a set of server computer systems that is associated with the computing environment, and the diversity constraint including a set of conditions that indicate restrictions on a set of hardware devices associated with the server computer system and the set of server computer systems;
• cause the server computer system to launch the compute instance based at least in part on the placement strategy and the diversity constraint;
• and
• update the database based at least in part on the placement information to indicate membership of the server computer system in a logical partition of the set of logical partitions, the logical partition supported by a plurality of servers of the set of server computer systems.
