  • High availability for a relational database management system as a service in a cloud platform
    Patent number: 11507479
    Abstract: A Relational Database Management System (“RDBMS”) as a service cluster may including a master RDBMS Virtual Machine (“VM”) node associated with an Internet Protocol (“IP”) address and a standby RDBMS VM node associated with an IP address. The RDBMS as a service (e.g., PostgreSQL as a service) may also include n controller VM nodes each associated with an IP address. An internal load balancer may receive requests from cloud applications and include a frontend IP address different than the RDBMS IP as a service addresses and a backend pool including indications of the master RDBMS VM node and the standby RDBMS VM node. A Hyper-Text Transfer Protocol (“HTTP”) custom probe may transmit requests for the health of the master RDBMS VM node and the standby RDBMS VM node via the associated IP addresses, and responses to the requests may be used in connection with a failover operation.
