20090327519 | ADDING INDIVIDUAL DATABASE FAILOVER/SWITCHOVER TO AN EXISTING STORAGE COMPONENT WITH LIMITED IMPACT - High availability architecture that employs a mid-tier proxy server to route client communications to active data store instances in response to failover and switchover. The proxy server includes an active manager client that interfaces to an active manager in each of the backend servers. State information and configuration information are maintained separately and according to semantics consistent with needs of corresponding data, the configuration information changing less frequently and more available, the state information changing more frequently and less available. The active manager indicates to the proxy server which of the data storage instances is the currently the active instance. In the event that the currently active instance is inactive, the proxy server selects a different backend server that currently hosts the active data store instance. Client communications are then routed to the different backend server with minimal or no interruption to the client. | 12-31-2009 |

20130191465 | FACILITATING MESSAGE SERVICES USING MULTI-ROLE SYSTEMS - Systems, methods, and software are provided for facilitating a message service. A multi-role system is identified based on where an active message database associated with a user identity resides. Service communications generated by a messaging client associated with the user identity are directed from an entry system to the multi-role system for handling in the multi-role system by a messaging server and a content server to provide the message service. | 07-25-2013 |
20130227028 | ENHANCED REPLICATION FOR MESSAGE SERVICES - Systems, methods, and software are disclosed that provide enhanced replication for message services. In one implementation, updates to a message source are replicated to message targets. The replication is monitored to identify an individual health of the replication for each of the message targets. A composite health of the replication is determined based on the individual health of the replication for each of the message targets. The updates to the message source are then controlled based on the composite health of the replication. | 08-29-2013 |
20130340075 | ENHANCED DATA PROTECTION FOR MESSAGE VOLUMES - In a message replication environment, instances of a message volume are hosted by message systems. Each message system exchanges condition information with the other message systems indicative of the health of the volume instance hosted by the message system. Each message system then determines independently from the other message systems whether or not the message volume is sufficiently protected. In the event that the message volume is insufficiently protected, a protection action can be initiated. | 12-19-2013 |
20130346512 | ENHANCED AVAILABILITY FOR MESSAGE SERVICES - An enhanced availability environment for facilitating a message service provided by a plurality of service elements is disclosed herein. The enhanced availability environment comprises a monitoring element and an enhanced availability element. The monitoring element monitors a first service element of the plurality of service elements for a monitored characteristic, generates monitoring information corresponding to the monitored characteristic, and communicates the monitoring information to the enhanced availability element. The enhanced availability element determines an availability of the first service element for the message service based at least in part on the monitoring information and an availability characteristic of the first service element, and communicates the availability to initiate an availability action. | 12-26-2013 |
20130346786 | DYNAMIC ESCALATION OF SERVICE CONDITIONS - Systems, methods, and software are provided for dynamically escalating service conditions associated with data center failures. In one implementation, a monitoring system detects a service condition. The service condition may be indicative of a failure of at least one service element within a data center monitored by the monitoring system. The monitoring system determines whether or not the service condition qualifies for escalation based at least in part on an access condition associated with the data center. The access condition may be identified by at least another monitoring system that is located in a geographic region distinct from that of the first monitoring system. Upon determining that the service condition qualifies for escalation, the monitoring system escalates the service condition to an escalated condition and initiates an escalated response. | 12-26-2013 |
20140351216 | ENHANCED REPLICATION - Systems, methods, and software are disclosed that provide enhanced replication for message services. In one implementation, updates to a replication source are replicated to replication targets. The replication is monitored to identify an individual health of the replication for each of the replication targets. A composite health of the replication is determined based on the individual health of the replication for each of the replication targets. The updates to the replication source are then controlled based on the composite health of the replication. | 11-27-2014 |
