ITIL (IT Infrastructure Library) is a framework for IT Service Management. It is arguably the most commonly used methodology for the design, 

 

Application Sizing ITIL® 

Before discussing what is Application Sizing ITIL® let’s understand the concept clearly. Capacity Management is the discipline that ensures IT infrastructure is provided at the right time in the right volume at the right price, and ensuring that IT is used in the most efficient manner.

 

Application Sizing ITIL® involves input from many areas of the business to identify what services are (or will be) required, what IT infrastructure is required to support these services, what level of Contingency will be needed, and what the cost of this infrastructure will be.

 

These are inputs into the following Capacity Management processes:

 

Performance monitoring Workload monitoring Application Sizing ITIL® Resource forecasting Demand forecasting Modeling

From these processes come the results of capacity management, these being the capacity plan itself, forecasts, tuning data, Service Level Management guidelines and lastly Application Sizing ITIL®. See the ITIL® Toolkit from http://www.ITIL®survival.com for more information on Capacity Management and contact us for more information about Application Sizing ITIL®.

 

Capacity Management and IT Security: A risk assessment of the capacity planning function will help ensure that the process is carried out effectively, and that its findings are acted upon along with Application Sizing ITIL®.

 

Benefits of Capacity Management and Application Sizing: ITIL® Capacity Management leads to increased efficiency and cost savings in several areas, including:

 

Deferred expenditure – if it is possible to defer the cost of new equipment to a later date, then the money that is currently in the budget can be spent in other ways. It may be possible to defer the expenditure permanently, so that the money need never be spent. Also, with the pace of technological change, the later a purchase is left, the more Capacity is obtained for the money Economic provision of services – Capacity is matched to business need. Unnecessary spare Capacity is not being maintained and therefore cost savings result. Use of existing Capacity is optimized as far as possible, again resulting in cost savings through not paying for unwanted Capacity during quiet usage periods Planned buying – is always cheaper than panic buying
Reduced risk is a major benefit of Capacity Management and Application Sizing ITIL®. Effective Capacity Management reduces the risk of performance Problems and failure in the following ways:

 

For existing applications the risk is minimized through managing the resources and service performance The risk to new applications is reduced through application sizing – as new applications can have an adverse effect upon existing applications, the risk to those applications is also minimized The Capacity Management process should be included on the Change Advisory Board (CAB) to assess the impact of Changes upon existing Capacity, thus reducing the risk of Capacity Problems caused by Changes The number of urgent Changes to increase Capacity are reduced, and hopefully eliminated, through effective Capacity planning
