Event-driven orchestration systems and methods for cloud-based job execution

A computerized method for orchestrating jobs on a cloud platform, the method comprising:

• capturing, by a server computing device, an event notification that is transmitted by the cloud platform after a specific event has occurred in the cloud platform, wherein the event notification is non-replayable and generated a single time by the cloud platform, and wherein the event notification is stored in an event notification database after being captured, the event notification including event notification metadata;
• determining, by the server computing device, a job corresponding to the event notification and one or more processing rules associated with the job based on the event notification metadata, wherein the one or more processing rules determine a manner in which to execute the job, and wherein the one or more processing rules include one or more processing actions that are performed before and after execution of the job;
• executing, by the server computing device, the one or more processing rules by evaluating machine-readable rule records that define execution dependencies and execution state transitions for the job;
• triggering, by the server computing device, the job for execution, after determining that each of the one or more processing rules has been successfully executed, by retrieving the event notification metadata from the event notification database;
• and
• executing, by the server computing device, the job on a compute instance that is generated specifically for the job, the compute instance being instantiated without shared persistent state and isolated from other compute instances, wherein the compute instance is terminated immediately after completion of the job execution to release compute resources and prevent cross-job interference.
