- 2. Virtualizing Business-Critical Applications Key Challenges: Ensuring Application Availability Low adoption beyond Tier 3 TIER 3 TIER 2 TIER 1 • Virtualization widely- adopted for non- critical applications Virtualization adoption • Business critical applications are infrequently virtualized IIS Apache WebLogic WebSphere SQL, Oracle SAP • Virtualization vendors Print File Exchange fail to ensure application availability Criticality of applications ApplicationHA 6.0 VMware 2
- 3. Application availability a key requirement for virtualization of critical apps Leading causes for unplanned outages1 Key challenges in managing virtualized servers2 Ensuring Application Availability 51% 40% Operations 20% Security, Power, Coordinating new deployments Errors OS, HW and upgrades 41% Managing unanticipated cost increases 42% Overcoming existing allocation, purchasing and budget 29% practices 40% Compensating for the lack of Application integrated management tools 32% Failures Gartner: 40% of failures are caused by the IDC: 51% of respondents rank Application application going down Availability as the key virtualization challenge 2.

Coordinated recovery between ApplicationHA and VMware HA • App monitoring VM1 VM2 VM1 VM2 – Show health status – Detect app failures ORA SQL ORA SQL • Coordinated recovery Application HA Application HA OS OS OS OS – Restart applications – Trigger VMware HA VMware HA VMware HA for further recovery VMware ESX VMware ESX – Integration via App Monitoring API • Protects against wide range of failures – Infrastructure failures – VM recovers after a server failure but app doesn’t – VM is up but app is down – App is up but not functional ApplicationHA 6.0 VMware 8
- 9. Coordinated recovery between ApplicationHA and VMware HA – Details VM1 • Deep understanding of the apps – App specific modules start, stop, recover apps App – Eg: SQL DB instances, FileStream, Analysis, Stora ge mount points, dependencies Agent – Functional testing based on SQL Pack queries Application EXCH SQL HA • Customizable recovery behavior ApplicationHA – App or VM restart limit OS – In-guest remediation only - Enable/Disable App Heartbeat VMware HA – Turn off remediation during planned maintenance - Enter/Exit Maintenance mode VMware ESX ApplicationHA 6.0 VMware 9
