Dynamically switching a software service between stateful mode and stateless mode

A method comprising:

• detecting, by a processor, an event associated with transitioning a software service from a stateless mode to a stateful mode;
• in response to detecting the event:
• causing, by the processor, a persistent volume to be allocated to the software service;
• and
• causing, by the processor, the software service to switch from (i) the stateless mode in which state information is not stored in the persistent volume to (ii) the stateful mode in which the state information is stored in the persistent volume,
• pausing, by the processor, requests from being transmitted to the software service while the software service is undergoing a transition from the stateless mode to the stateful mode;
• routing, by the processor, the requests to a destination other than the software service while the software service is undergoing the transition from the stateless mode to the stateful mode, wherein the destination is a buffer;
• determining, by the processor, that the transition is complete;
• and
• based on determining that the transition is complete:
• extracting, by the processor, the requests from the buffer and transmitting the requests to the software service;
• and
• allowing, by the processor, additional requests to be transmitted to the software service.

A system comprising:

• a processor;
• and
• a non-transitory computer-readable memory including instructions that are executable by the processor for causing the processor to:
• detect an event associated with transitioning a software service from a stateless mode to a stateful mode;
• in response to detecting the event:
• cause a persistent volume to be allocated to the software service;
• and
• cause the software service to switch from (i) the stateless mode in which state information is not stored in the persistent volume to (ii) the stateful mode in which the state information is stored in the persistent volume;
• pause requests from being transmitted to the software service while the software service is undergoing a transition from the stateless mode to the stateful mode;
• route the requests to a destination other than the software service while the software service is undergoing the transition from the stateless mode to the stateful mode, wherein the destination is a buffer;
• determine that the transition is complete;
• and
• based on determining that the transition is complete:
• extract the requests from the buffer and transmit the requests to the software service;
• and
• allow additional requests to be transmitted to the software service.
