CHEP 2019 - Achieving metric oriented load balancing
Abstract The Load Balance Service at CERN handles more that 400 aliases, distributed over more than 2000 nodes. After being in production for more than thirteen years, it has been going through a mayor redesign over the last two years. Last year, the server part got reimplemented in golang, taking advantage of the concurrency features offered by the language to improve the scaling of the system. This year, the client side and the communication between the client and the server have been the main focus.
