Scalable service discovery and load balancing using direct client connections to servers

Abstract

There are provided systems and methods for scalable service discover and load balancing using direct client connections to servers. A service provider, such as an electronic transaction processor for digital transactions, may provide different computing services to users through client devices, which utilize server instances from server pools and the like to provide the computing services to users. This may include providing servers to handle client requests and process data with users. When client devices connect to the service provider's system, service discovery may be performed to find an available server instance to handle client requests. To provide scalable service discovery, load balancers may, instead of managing client requests through the load balancers, ping server instances from a server pool to identify a network address of an available server. This may be returned to the client device and a direction connection may be made between the device and server.
