What is Application Performance Management?
Application performance management (APM), is the monitoring and managing of performance and availability of primarily software applications.
The function of APM is to to detect and diagnose application performance problems to maintain an expected level of service – often to agreed SLA’s.
APM is a key tool for IT Management to aid the understanding of software and application performance metrics into business meaning e.g. downtime to busness, systems reliability and response times to name a few.
Most Application Performance Management tools help unifies systems, network, and application monitoring – and gives IT the capabilities to proactively ensure that application performance meets user expectations and business priorities. With Application Performance Management tools the IT function can pinpoint issues early and fix them before service degrades.
Application Performance Management helps:
- Proactively ensure continuous up-time with alerts and automatic repair of potential problems – before users are affected.
- Quickly identify root causes of application performance problems— across network, server or multi-tier application or component dependencies
- Gain the valuable insight necessary to improve application performance and availability – through real-time and historical reporting and analysis.
APM tools provide insight and data to rapidly find and assess the impact of issues, isolate the cause, and restore performance levels.
How do you calucate the Total Cost of Ownership per gigabyte of storage – our breakdown of this is as follows based on analysis of customer installations, cost of storage (based on EMC hardware) and administrative and backup costs:
|Initial Cost||Depreciated Cost per Annum (4 Years)|
|Cost of Storage Hardware per GB||£4.61||£1.15|
|Cost of Backup Hardware per GB||£9.52||£2.38|
|Cost of Administration per GB Current||£0.24||£0.24|
|Total Cost per GB||£14.37||£3.77|
This gives a Total Cost of ownership per GB of £14.37 and an ongoing TCO of £3.77
Some customers have used figures as high as £18 per GB for TCO so a range may be appropriate.
