Sistema de failover automatizado com monitoramento sintético para LDAP do Laboratório de Sistemas Distribuídos da UFCG.

Abstract

Lightweight Directory Access Protocol (LDAP) is a protocol targeted to applications that provide interactive read-write access to a directory. This protocol is used by the Distributed Systems Laboratory (LSD) at the Federal University of Campina Grande (UFCG) in storing user data for internal systems and to provider their authentication. In cases of failure of this system — whether network failures, lack of resources or any other — several other laboratory systems are compromised, since the user needs to be authenticated to use them. This includes services in the lab's own data center as well as services in public clouds. In this work, we will plan and develop a solution for the implementation of a failover targeting LSD's LDAP. This failover will aim to guarantee access to LSD user data even if the LDAP system becomes unavailable. It will do this by monitoring that system and, in case of failure, automatically deploying a replica of it in a public cloud.
