7. The computer-implemented method of claim 1 , wherein relocating each of the plurality of microservices comprises:
determining whether the property of the monitored traffic satisfies a predetermined requirement; and
responsive to the property of the monitored traffic satisfying the predetermined requirement, relocating each of the plurality of microservices from its respective origin resource to the shared resource.
8. The computer-implemented method of claim 7 , wherein the predetermined requirement comprises at least one of:
an amount of data being greater than or equal to a predetermined threshold;
a type of the data being a predetermined type; and
a flow rate of the data being greater than or equal to a predetermined threshold.
9. The computer-implemented method of claim 1 , wherein monitoring traffic between the plurality of microservices comprises:
receiving requests communicated between the plurality of microservices; and
monitoring traffic associated with the received requests.
10. The computer-implemented method of claim 1 , wherein relocating each of the plurality of microservices comprises, for each of the plurality of microservices:
maintaining a first instance of the microservice at its origin resource;
restarting a second instance of the microservice at the shared resource; and
shutting down the second instance of the microservice at its respective origin resource.
11. A computer program product comprising:
one or more computer readable storage media and program instructions stored on the one or more computer readable storage media, the program instructions comprising:
program instructions to, in response to receiving requests communicated between a plurality of microservices, determine a property of traffic by to monitoring traffic between the plurality of microservices; and
program instructions to relocate each of the plurality of microservices temporarily from its respective origin resource to a shared resource based on the determined property of the monitored traffic.
12. The computer program product of claim 11 , wherein the program instructions to relocating each of the plurality of microservices comprises:
for each of the plurality of microservices, program instructions to restart the microservice at the shared resource and shutting down the microservice at its origin resource.
13. The computer program product of claim 11 , wherein the program instructions to relocate each of the plurality of microservices comprise:
program instructions to reconfigure communication between the plurality of microservices by collecting the plurality of microservices from each of their respective origin resources to the shared resource.
14. The computer program product of claim 11 , wherein the program instructions to relocating each of the plurality of microservices comprise:
program instructions to determine whether the property of the monitored traffic satisfies a predetermined requirement; and
program instructions to, responsive to the property of the monitored traffic satisfying the predetermined requirement, relocate each of the plurality of microservices from its respective origin resource to the shared resource.
15. The computer program product of claim 11 , wherein the program instructions to monitoring traffic between the plurality of microservices comprise:
program instructions to receive requests communicated between the plurality of microservices; and
program instructions to monitor traffic associated with the received requests.
16. The computer program product of claim 11 , wherein the program instructions to relocating each of the plurality of microservices comprises, for each of the plurality of microservices comprise:
program instructions to maintain a first instance of the microservice at its origin resource;
program instructions to restart a second instance of the microservice at the shared resource; and
program instructions to shut down the second instance of the microservice at its respective origin resource.
17. A computer system for 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 computer processors, the program instructions comprising:
program instructions to, in response to receiving requests communicated between a plurality of microservices, determine a property of traffic by to monitoring traffic between the plurality of microservices; and
program instructions to relocate each of the plurality of microservices temporarily from its respective origin resource to a shared resource based on the determined property of the monitored traffic.
18. The computer system of claim 17 , wherein the program instructions to relocating each of the plurality of microservices comprises:
