Abstract

Methods and apparatus for managing user-defined capacity reservation pools for network-accessible resources are disclosed. A system includes a plurality of resource instances of a provider network, and a resource manager. In response to a pool assignment request from a client specifying a pool identifier of a reserved instance pool created on behalf of the client, the resource manager assigns one or more resource instance reservations of the client to a pool with the first pool identifier. In response to an instance activation request from the client, the resource manager identifies a particular pool created on behalf of the client from which to select a particular resource instance reservation for activation, and activates the particular resource instance.

Claims

one or more hardware computing devices configured to implement a resource manager, wherein the resource manager is configured to;

in response to receiving, from a first client, a pool assignment request specifying a first pool identifier, assign a first one or more resource instance reservations to a first reserved instance pool, wherein the first pool identifier identifies the first reserved instance pool;

create a link between the first reserved instance pool identified by the first pool identifier and a second reserved instance pool identified by a second pool identifier, wherein a second one or more resource instance reservations are assigned to the second reserved instance pool; and

in response to receiving, from the first client, an instance activation request specifying the first pool identifier identifying the first reserved instance pool;

identify a particular reserved instance pool from which to select a particular resource instance reservation for activation, wherein to identify the particular reserved instance pool, the resource manager is configured to;

determine whether there are sufficient resource instances in the first reserved instance pool to satisfy the instance activation request; and

select, based at least on a determination that there are insufficient resource instances in the first reserved instance pool to satisfy the instance activation request and on the link between the first reserved instance pool and the second reserved instance pool, the second reserved instance pool as the particular reserved instance pool from which to select the particular resource instance reservation for activation; and

activate on one of the plurality of hardware computing devices and responsive to the instance activation request that specifies the first pool identifier and based at least in part on said select the second reserved instance pool as the particular reserved instance pool, a particular resource instance of the plurality of resource instances corresponding to the second one or more resource instance reservations of the second reserved instance pool.

2. The system as recited in claim 1, wherein, prior to assigning the first one or more resource instance reservations, the resource manager is further configured to:

in response to a pool creation request from the first client specifying the first pool identifier, create the first reserved instance pool with the first pool identifier.

3. The system as recited in claim 1, wherein the resource manager is further configured to:

in response to a reservation transfer request specifying the particular pool as a source pool and another reserved instance pool created on behalf of the first client as a destination pool, transfer the particular resource instance reservation from the particular pool to the other pool.

4. The system as recited in claim 1, wherein the resource manager is further configured to:

in response to an account linkage request specifying (a) an account identifier and (b) the first pool identifier, link the account identifier to the first pool identifier; and

transmit, to an owner of the account with the specified account identifier, a report associated with a resource instance reservation assigned to the pool identified by the first pool identifier.

5. The system as recited in claim 1, wherein the resource manager is further configured to:

in response to (a) a pool sharing request specifying that the first client and a second client are to share access to a particular pool, and (b) a request for a resource instance reservation from the second client, assign a resource instance reservation from the particular pool to the second client.

6. The system as recited in claim 1, wherein the interface manager is further configured to:

implement one or more programmatic interfaces allowing a client to specify a pool identifier of a reserved instance pool from which a resource instance reservation is to be selected in response to at least one of;

an instance activation request, a report request, an instance status request, an instance description request, or a reservation transfer request;

7. A method, comprising:

performing, by one or more hardware computing devices;

in response to receiving, from a first client, a pool assignment request specifying a first pool identifier, assigning a first one or more resource instance reservations to a reserved instance pool, wherein the first pool identifier identifies the first reserved instance pool;

creating a link between the first reserved instance pool identified by the first pool identifier and a second reserved instance pool identified by a second pool identifier; and

in response to receiving, from the first client, an instance activation request specifying the first pool identifier identifying the first reserved instance pool;

identifying a particular pool from which to select a particular resource instance reservation for activation, wherein said identifying comprises;

determining whether there are sufficient resource instances in the first reserved instance pool to satisfy the instance activation request; and

selecting, based at least on determining that there are insufficient resource instances in the first reserved instance pool to satisfy the instance activation request and on the link between the first reserved instance pool and the second reserved instance pool, the second reserved instance pool as the particular reserved instance pool from which to select the particular resource instance reservation for activation; and

activating, responsive to the instance activation request specifying the first pool identifier and based at least in part on said selecting the second reserved instance pool as the particular reserved instance pool, a particular resource instance of the plurality of resource instances corresponding to a second one or more resource instance reservations of the second reserved instance pool.

8. The method as recited in claim 7, further comprising:

including, within a report provided to the first client for use of the particular resource instance, an indication of a pool identifier of the particular pool.

9. The method as recited in claim 7, further comprising:

prior to assigning the first one or more resource instance reservations, creating the first reserved instance pool with the first pool identifier in response to a pool creation request from the first client.

10. The method as recited in claim 7, further comprising:

in response to a reservation transfer request specifying the particular pool as a source pool and an other reserved instance pool created on behalf of the first client as a destination pool, transferring the particular resource instance reservation from the particular pool to the other pool.

11. The method as recited in claim 7, further comprising:

in response to an account linkage request specifying (a) an account identifier and (b) the first pool identifier, linking the account identifier to the first pool identifier; and

transmitting, to an owner of the account with the specified account identifier, a report associated with a resource instance reservation assigned to the pool identified by the first pool identifier.

12. The method as recited in claim 7, further comprising:

in response to (a) a pool sharing request specifying that the first client and a second client are to share access to the particular pool, and (b) a request for a resource instance reservation from the second client, assigning a resource instance reservation from the particular pool to the second client.

13. The method as recited in claim 7, further comprising:
