Failover service to support high availability of monolithic software applications

One or more non-transitory machine-readable media comprising program code for a first agent providing failover service for a first application, the program code to:

• configure the first agent with a first resource for determining a status of the first application executing on a first device, wherein the first agent executes independently of the first application on the first device;
• configure the first agent with an identifier and a second resource for initializing a second application executing on a second device;
• determining a first status of the first application based, at least in part, on the first resource;
• store the first status and a first timestamp corresponding to the first status to a database;
• retrieve, using the identifier for the second application, a second status and a second timestamp from the database, wherein the second status and the second timestamp were stored on the database by a second agent executing on the second device;
• determine that the second application has failed based, at least in part, on the second status and the second timestamp;
• and
• based on determining that the second application has failed, initialize the second application on the first device using the second resource.

An apparatus comprising:

• a processor;
• and
• a machine-readable medium having program code executable by the processor to cause the apparatus to,
• configure a first agent with a first resource for determining a status of a first application executing on a first device, wherein the first agent executes independently of the first application on the first device;
• determine, by the first agent, a first status of the first application based, at least in part, on the first resource;
• store, by the first agent, the first status and a first timestamp corresponding to the first status to a database;
• retrieve, by a second agent, the first status and the first timestamp from the database, wherein the second agent executes on a second device;
• determine, by the second agent, that the first application has failed based, at least in part, on the first status and the first timestamp;
• and
• based on a determination that the first application has failed, initialize, by the second agent, the first application on the second device,
• wherein the second agent was previously configured with a second resource for initializing the first application.
