Dynamic placement of services closer to endpoint

A system comprising:

• a network fabric comprising one or more spine switches and multiple leaf switches with a centralized service deployed on at least one spine switch and a plurality of distributed services deployed at one or more of the leaf switches, implementing registration for one or more endpoints of the network fabric, wherein one or more of the spine switches, one or more of the leaf switches, or a combination thereof perform steps comprising:
• sending, from the plurality of distributed services deployed among the multiple leaf switches, multicast Domain Name System (mDNS) messages to corresponding direct discovery controllers (DDCs);
• responsive to a distributed service receiving a response from a corresponding DDC, sending from the distributed service to the centralized service a request for adding the corresponding DDC, the response comprises a DDC internet protocol (IP) address of the corresponding DDC;
• updating, by the centralized service, a DDC database and sending, from the centralized service, an inquiry to a networking operating system (NOS) of the network fabric regarding the DDC IP address;
• checking, by the NOS, one or more Address Resolution Protocol (ARP) entries related to one or more leaf switches of a set of leaf switches to determine a leaf switch wherein the DDC IP address is associated;
• instantiating, by the centralized service, a non-volatile memory express (NVMe) service handler to deploy a microservice on the determined leaf switch;
• and
• upon microservice deployment, sending, from the determined leaf switch, an NVMe connection request to the corresponding DDC to complete pull registration for the corresponding DDC.

One or more non-transitory computer-readable media comprising one or more sequences of instructions which, when executed by at least one processor, given a network fabric comprising one or more spine switches and multiple leaf switches with a centralized service deployed on at least one spine switch and a plurality of distributed services deployed at one or more of the leaf switches, causes steps to be performed comprising:

• sending, from the plurality of distributed services deployed among the multiple leaf switches, multicast Domain Name System (mDNS) messages to corresponding direct discovery controllers (DDCs);
• responsive to a distributed service receiving a response from a corresponding DDC, sending from the distributed service to the centralized service a request for adding the corresponding DDC, the response comprises a DDC internet protocol (IP) address of the corresponding DDC;
• updating, by the centralized service, a DDC database and sending, from the centralized service, an inquiry to a networking operating system (NOS) of the network fabric regarding the DDC IP address;
• checking, by the NOS, one or more Address Resolution Protocol (ARP) entries related to one or more leaf switches of a set of leaf switches to determine a leaf switch wherein the DDC IP address is associated;
• instantiating, by the centralized service, a non-volatile memory express (NVMe) service handler to deploy a microservice on the determined leaf switch;
• and
• upon microservice deployment, sending, from the determined leaf switch, an NVMe connection request to the corresponding DDC to complete pull registration for the corresponding DDC.
