Systems and methods for service replication, validation, and recovery in cloud-based systems

A cloud-based system configured for replication and validation between a plurality of nodes in a cluster, the cloud-based system comprising:

• a plurality of nodes each configured to replicate a database and a software state between one another utilizing a replication algorithm which elects a master of the plurality of nodes and remaining nodes as peers, wherein the master is configured to perform replication;
• wherein each of the plurality of nodes is configured to validate database sequences utilizing the replication algorithm to ensure sequential order of the validation between the plurality of nodes, and
• wherein, responsive to differences between a peer and the master in the validation, a failure recovery is performed for the database at the peer, wherein the database of the peer and the master are verified utilizing the replication algorithm without closing an application interacting with the database and while honoring requests from the application to the database during the verification, wherein the verification is performed through a replication operation using the replication algorithm to perform a database dump which is verified offline with a tool for comparison, and wherein the comparison omits one or more fields in the database between the peer and the master, wherein the one or more fields are inherently different.
