Resilient and decentralized microservice architecture

A resilient microservice system, comprising:

• a plurality of microservice computing nodes;
• a first distributed computing sub-system comprising a respective combination of at least some of the microservice computing nodes;
• and
• a second distributed computing sub-system, comprising a respective different combination of at least some of the microservice computing nodes;
• wherein as a result of at least some procedure calls all conveying a same first message that were just made available in the first distributed computing sub-system, each of at least some of the nodes in the first distributed computing sub-system is configured to:
• execute, in conjunction with at least some of the other nodes of the first distributed computing sub-system, a consensus mechanism associated with the first message;
• process the first message;
• and
• provided that an agreement has been reached in conjunction with said consensus mechanism, send a remote procedure call (RPC) conveying a second message, which is consequent on said processing, to at least one of the nodes of the second distributed computing sub-system;
• so as to result in the second distributed computing sub-system receiving at least some of the RPCs conveying the same second message.
