Abstract

Methods, systems, and computer-readable media for implementing a routing handler for rule-based action triggering are disclosed. A request is received at a routing handler from a client. The request specifies a particular operation at a particular one of a plurality of sub-services. The sub-services comprise one or more operations for defining a plurality of rules; the rules are defined to bind triggers to actions. The sub-services also comprise one or more operations for performing the actions in a provider network comprising a plurality of resources. The particular operation in the request is determined at the routing handler. The particular one of the sub-services is determined at the routing handler based on the particular operation, using a routing map. The routing map is dynamically updated when operations provided by sub-services are modified. The request is routed to the particular one of the sub-services.

return a client response to the client based at least in part on the one or more responses.

2. The system as recited in claim 1, wherein the plurality of sub-services comprise a scheduling sub-service, wherein the scheduling sub-service comprises one or more operations for scheduling individual ones of the actions at particular times.

3. The system as recited in claim 1, wherein, in response to modification of the one or more operations at the rules sub-service or modification of the one or more operations at the actions sub-service, an updated routing map is generated based at least in part on the routing map, wherein the updated routing map comprises a mapping of one or more new or modified operations to a particular one of the sub-services, and wherein the updated routing map is stored in the data store.

4. The system as recited in claim 1, wherein to route the request to the one or more sub-services, the routing handler is configured to route the request via one or more sub-service clients configured to wait for respective responses from the one or more sub-services.

5. A computer-implemented method, comprising:

receiving, at a routing handler from a client, a request that specifies a particular operation at one or more of a plurality of sub-services, wherein the plurality of sub-services comprise a rules sub-service that performs one or more operations for defining a plurality of rules, wherein individual ones of the rules are defined to bind a respective one or more of a plurality of triggers to a respective one or more of a plurality of actions, and wherein the plurality of sub-services comprise an actions sub-service that performs one or more operations for performing the plurality of actions in a provider network comprising a plurality of resources;

determining, at the routing handler, the particular operation in the request;

selecting, at the routing handler, the one or more sub-services based at least in part on the particular operation in the request, wherein the one or more sub-services includes the rules sub-service and is selected via a lookup in a routing map that maps individual operations to respective one of the plurality of sub-services that provide the individual operations and is shared by the routing handler and one or more additional routing handlers;

routing the request to the one or more sub-services including the rules sub-service;

receiving one or more responses to the request from the one or more sub-services, including one or more messages from the rules sub-service describing one or more of the actions specified in one or more of the rules that are triggered by the particular operation;

sending one or more additional requests to one or more additional sub-services of the plurality of sub-services including the actions sub-service to perform the one or more actions, wherein the one or more additional sub-services are selected via the routing map; and

returning a client response to the client based at least in part on the one or more responses.

6. The method as recited in claim 5, wherein receiving the one or more messages from the rules sub-service comprises receiving the one or more messages from a messaging service.

7. The method as recited in claim 5, wherein the actions sub-service comprises a plurality of action handlers configured to execute in an action execution environment implemented in the provider network.

8. The method as recited in claim 5, wherein the plurality of sub-services comprise a scheduling sub-service, wherein the scheduling sub-service comprises one or more operations for scheduling individual ones of the actions at particular times.

9. The method as recited in claim 5, wherein the routing map is dynamically loaded from a data store to the routing handler, and wherein the method further comprises:

generating an updated routing map based at least in part on the routing map, wherein the updated routing map comprises a mapping of one or more new or modified operations to a particular one of the sub-services; and

storing the updated routing map in the data store.

10. The method as recited in claim 5, wherein routing the request to the one or more sub-services comprises routing the request via one or more sub-service clients configured to wait for respective responses from the one or more sub-services.

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