Abstract: Methods, apparatus and articles of manufacture to propagate node changes in a cluster of nodes and reconfigure services based on the node changes in a cloud computing environment are disclosed. Example methods disclosed herein include analyzing a node change event message at a first node of the plurality of nodes to identify a node change event type contained in the node change event message. The node change event type corresponds to a node change event experienced by a second node of the plurality of nodes. Example methods also include selecting, based on the node change event type, a script from a data storage installed in the first node, and reconfiguring, by executing the script at the first node, a service supported by the first node. Still further example methods, include broadcasting, to the plurality of nodes including the first node, the node change event message from the second node.

Abstract: Methods, apparatus, and systems to perform transparent database switching using master-replica high availability setup in relational databases are disclosed. An example system includes a first virtual appliance including a first proxy and a master database, the first proxy to forward service traffic to the master database, the master database to read and/or write data based on the service traffic; a second virtual appliance including a second proxy and a first replica database, the second proxy to determine data stored in the master database, the first replica database to replicate the master database; and a third virtual appliance including a third proxy and a second replica database, the third proxy to, in response to determining the master database of the first virtual appliance is to power down, promote the second replica database to the master database.
