Supporting high availability for orchestrated services

A computing system comprising:

• one or more computer processors;
• one or more computer readable storage media;
• and
• program instructions stored on the one or more computer readable storage media for execution by at least one of the one or more processors, the program instructions comprising:
• a first group and a second group, wherein the first group is configured to process a plurality of active services, and wherein the second group is configured to process a plurality of standby services;
• a switching mechanism on the first group and the second group, wherein the plurality of active services can be activated and deactivated, and wherein the plurality of standby services can be activated and deactivated;
• a router, wherein the router is configured to receive a request from a user and forward the request to the first group;
• a service health monitor, wherein the service health monitor is configured to monitor and record a health status of the first group and of the second group;
• a repository, wherein the repository is configured to store changes of a plurality of services and record changes of the plurality of services;
• a version control manager, wherein the version control manager is configured to recall the second group and move it to the first group, based in part on an indication from the service health monitor and a change order recorded in the repository;
• program instructions to record a first version combination wherein the first version combination is the set of active services in the first group;
• program instructions to monitor the plurality of active services of the first group, wherein monitoring the plurality of active services comprises program instructions to request a query status, at predetermined time intervals, of each service of the plurality of active services;
• program instructions to receive an error notification, wherein the error notification identifies a crash in at least one service of the plurality of active services of the first group and wherein the error notification comprises information regarding the error;
• responsive to receiving the error notification, program instructions to detect whether the second group is offline;
• responsive to detecting that the second group is offline, program instructions to bring the second group to online;
• responsive to receiving the error notification, program instructions to deactivating the at least one service of the plurality of active services of the first group that is associated with the error notification, and program instructions to activate at least one service of the plurality of standby services from the second group that corresponds to the deactivated at least one service of the first group;
• responsive to receiving the error notification, program instructions to detect, at least one broken service, responsible for the crash from the plurality of services of the first group, and generate a crash report and forwarding it to a service provider of the broken service;
• and
• responsive to deactivating the at least one service and activating the at least one service, program instructions to record a second version combination wherein the second version combination is the set of active services in the second group.
