Brief Introduction Of Capacity Management
ANSWER: The main aim of Capacity management is to make sure that the information technology resources are of correct size in order to achieve the current and the future business organization`s requirements in a good “cost effective manner”. One of the most common understanding and interpretation of the capacity management is well described in the “Information Technology Infrastructure Library” framework (ITIL Framework). Version 3 of Information Technology Infrastructure Library framework (ITIL Framework) describes the capacity management to be consisting of three sub processes those are “business capacity management, service capacity management, and component capacity management which is also known as resource capacity management in version 2 of “Information Technology Infrastructure Library (ITIL).
When Did The Capacity Management Has Been Started And Whom?
ANSWER: It is not exactly known when did the concept and idea of capacity management has started and by whom. However, it could be said and assumed that with the introduction of industrialization and with the advancement of science and technology, the idea and the concept of capacity management was introduced in the Business scenario.
Need Of This Capacity Management
ANSWER: Capacity Management is need to monitor the loan and throughput or the loan on the server, the server farm or the property Capacity Management is used in the analysis of the performance measurement data which may include analysis of the impact of the new releases on the capacity. Capacity Management may include tuning of the performance activities to make the most effective usage of the existing infrastructure. Capacity Management helps in better understanding of the demands of the services and future plans for the overall growth in the workload and shrinkage. Capacity management has an influence on the demand for computing resources. Capacity management plans on capacity planning and which works on storage, computer hardware, software and the various connection infrastructures resources that requires a certain period of time.
Uses Of The Capacity Management
ANSWER: The various usage of the Capacity Management mainly involves the Information Technologies (IT). With the advancement of science and technologies, the usage and the function of the different Information Services has changed evolved functionally over the time. As a result, the amount of Central Processing Unit (CPU) and the memory space and the storage to the physical and the virtual world has also changed and evolved. “If it is possible to understand the demands being made currently, and how they will change over time, this approach proposes that capacity planning for IT service growth becomes easier and less reactive”. If there is a increase in the processing power of the at any particular time of the day, the capacity management helps in analyzing “what is happening at that time and make changes to maximize the existing IT infrastructure, for example, tune the application, or move a batch cycle to a quieter period. This foresight from proactive capacity planning identifies: any potential capacity related issues likely to arise and justifies any necessary investment decisions to the business and IT stakeholders i.e. the precise server requirements to accommodate a future growth in IT resource demand, a technology refresh or a data center consolidation”. The capacity management also communicates with the various discipline especially, the discipline of the performance Engineering. Both capacity management and the discipline of the performance engineering interacts during the “requirements and design activities of building a system, and when using performance monitoring as an input for managing capacity of deployed systems”.
Criticism Of Capacity Management
ANSWER: The various criticisms involves with the capacity management especially in the Information Technology sector mainly includes delays. “It can take a long time for a packet to be delivered across intervening networks. In reliable protocols where a receiver acknowledges delivery of each chunk of data, it is possible to measure this as round-trip time”. There are also losses of Packet. In some cases packets will be lost in the “intermediate devices in a network”, mainly due to the various errors like the overloading of the intermediate network or the international discarding of the traffic in order to implement a particular service level. When the data are lost, two losses are incurred. Those mainly includes “the delay from re-sending the data; and second, the delay resulting from waiting until the data is received in the correct order before forwarding it up the protocol stack”.
Related Topic And Concept Of Capacity Management.
ANSWER: Taking about the capacity management and the related topics, three topics that may be included are Potential Capacity, Immediate Capacity and the Effective capacity.
