To effectively manage a complex business application or service, IT organizations need a solution that can maintain an accurate map of the underlying infrastructure and its changing dependencies. Automatic application dependency mapping is a critical step toward effective service management, providing the link between business services, applications, and the supporting infrastructure.
Let’stake a look at how BMC is assisting customers in making this transition. The first place we will start is at the heart of an ITSM solution, the CMDB.
BMC Atrium Discovery uses an agent-less approach to discover instances of distributed applications, as well as their dependency components, such as software instances, databases, servers, and network switches. It also automatically maintains these application dependency maps over time.
Patterns provide a simple, powerful, and flexible way to define how software and business application instances are identified. Patterns infer the existence of software and business application instances along with their dependencies from discovered configuration data, and as a result, dependency maps are automatically refreshed each time BMC Atrium Discovery performs a scan of the environment.
BMC Atrium Discovery ships with the industry’s most extensive knowledge library of patterns that model commonly deployed software and business applications, such as SAP®and Oracle® E-Business Suite. The library is updated monthly to enhance and update existing patterns and to create new patterns to increasecoverage of discoverable products. Having such broad coverage of out-of-the-box patterns accelerates the speed at which application dependency maps can be created and maintained.
Datacenter environments will no doubt comprise of a broad range of custom softwareand business applications. BMC Atrium Discovery provides pattern templates to enable rapid modeling of custom software and business applications.
For virtual environments, integration with BMCAtrium Orchestrator and VMware Virtual Center enables BMC Atrium Discoveryto automatically detect real-time virtual relationship changes and trigger a targeted rescan to keep the application dependency map current.
Discovered data is continuously synchronized with the BMC Atrium Configuration Management Database (CMDB). As part of the synchronization process, the BMC Atrium CMDB Normalization Engine uses industry best-practicerules to assign impact details for each dependency relationship. Havingthis additional context about the impact of dependency relationships enables change managers and service desk staff to effectively assess the businessimpact of a change, prioritize incidents and target investigation.
For example, the service impact for a standalone server will be higher than that o fa server that is part of a cluster. A catastrophic failure on a stand-alone server could render the business application or service unavailable, resulting in the highest severity alert. Conversely, a catastrophic failure on a server that is part of a cluster will likely only impair the service, thus resulting in a lower severity alert.
