Deployment of microservices based on back-end resource affinity

A computer system for determining microservice placement to minimize response time in a network, the computer system comprising:

• a bus system;
• a storage device connected to the bus system, wherein the storage device stores program instructions;
• and
• a processor connected to the bus system, wherein the processor executes the program instructions to:
• identify a set of resources utilized by a microservice during operation of the microservice based on inspecting a configuration file and code of the microservice;
• determine a deployed location within the network of each resource in the set of resources utilized by the microservice;
• assign a relative weight value to each resource in the set of resources utilized by the microservice indicating a relative significance of each respective resource to the microservice during operation;
• determine a weighted-average response time for each data center in a set of possible data centers to deploy the microservice based on the relative weight value assigned to each respective resource utilized by the microservice and a determined distance value measured by response time between the deployed location of each respective resource in the set of resources and each respective data center in the set of possible data centers where the microservice may be deployed;
• select a data center in the set of possible data centers to deploy the microservice based on the data center having a lowest determined weighted-average response time;
• and
• deploy the microservice to the data center having the lowest determined weighted-average response time to minimize response time of the microservice in the network.
