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.

Abstract: Methods and apparatus to propagate an update between nodes in a distributed environment are disclosed. An example apparatus includes a first virtual appliance configured to install an update using an update file from a first update repository, the first update repository located apart from the first virtual appliance, the first virtual appliance configured to form a second update repository at the first virtual appliance, the second update repository to include a copy of the update file from the first update repository. The example apparatus also includes a second virtual appliance, the second virtual appliance formed as a replica of the first virtual appliance, the second virtual appliance to install the update using the copy of the update file from the second update repository.

Abstract: Methods, apparatus, systems and articles of manufacture for automatic database failover in a master-replica replication configuration are disclosed. An example node within a database system having a plurality of nodes, includes an agent to select a first database operated at one of the plurality of nodes to function as a master database in a master-replica replication configuration. The agent is to cause the selected database to be configured as the master database. The agent is to configure a first reverse proxy of the node. The first reverse proxy is to receive a query from a load balancer and forward the query to the master database based on the configuration.

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. An example first node of an example cluster of nodes includes an event reporter to, in response to experiencing a node change event, transmit a node change event message to a second node, the node change event message to trigger the second node to perform at least one action to reconfigure a service supported by the second node, the at least one action to reconcile the service with the node change event; and an event listener to receive an event reporting message from the second node, the event reporting message indicative of whether the second node successfully performed the at least one action.

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.
