Capacity Planning And Performance Modeling

A:- STORAGE REQUIRMENTS: There are 2 sources of capacity requirements:- business and technical requirements of the organization. The technical requirements are dictated by need and availability. You should also determine the business goals of the organization for which you’re developing the database infrastructure. Without knowing those, you cannot analyse or forecast its capacity needs, any more than you can make the best possible house without knowing what it will be used for.

Cloud computing reduces costs which helps provide businesses save on yearly expenses. A benefit of Cloud Computing is the Scalability factor, companies can start with one server reduce services to the bare minimum needed by the business. Then as the demand rises, they can then increase their cloud utilization to meet their new needs. “In addition, cloud computing is scalable. Traditional servers require expensive upgrades that cost a lot upfront. If your business doesn’t expand as much as you had hoped, that’s money you’ve wasted. Cloud service providers usually let you scale up and down seamlessly.” (Ismail, N, 2017)

Cloud computing can be defined as an internet based computing model that can be used to provide services to multiple users, simultaneously, as and when requested. The Common wealth Bank of Australia (CBA) included cloud service models in their IT infrastructure quite recently, and has released in public the details of this project. The white paper released in public provides the details of the cloud model implemented by the organization, along with the factors that had driven the project and the benefits that have been availed from the project. This article is aimed at providing a detailed description of infrastructure that has been adapted by the Common Wealth Bank. Discussions have also been made on the challenges that were

Reordering the economics of software, cloud computing is alleviating many of the capital expenses (CAPEX), inflexibility of previous-generation software platforms, and inability of on-premise applications to be customized on an ongoing basis to evolving customer needs. These are the three top factors of many that are driving the adoption of cloud computing technologies in enterprises today. Implicit in the entire series of critical success factors that are forcing the migration of on-premise to cloud computing platforms is the greater agility and speed the latter platform offers. Line-of-business executives today are increasingly defining the priorities of IT departments, often also defining budgeting cycles as well. Their primary concern is ability able to quickly get up and running on a new enterprise application, integrating its workflows into existing legacy and 3rd party systems, databases and applications, while also getting the performance gains of the new software (Bentley, 2008). Due to these factors cloud computing is evolving rapidly, changing the economics of enterprise software especially. Large-scale systems are most often purchased using Capital Expense (CAPEX) budgeting processes that often take several months ot over a year to complete. Often CAPEX-based spending on enterprise software also requires the board of directors for a company to authorize spending large amounts on new

Cloud computing is a relatively new technology that allows data to be stored, distributed and manipulated with greater ease than ever. As described by Gurjar and Rathore (2013), the “Cloud is a large pool of easily usable and accessible virtualized resources. These resources can be dynamically reconfigured to adjust to a variable load, allowing also for an optimum resource utilization” (p. 1). By moving data, documents and media to the Cloud, the potential for business efficiency and productivity increases and anyone with internet can take advantage of the benefits. As with anything, it is important to understand the risks and benefits in order to weigh whether or not moving to the Cloud is the best move for the business. Some companies,

Distributed computing has turned into a massive market. In a 2016 report, investigators at Gartner anticipated that the move to the cloud will influence more than $1 trillion in IT spending throughout the following five years. "Cloud-first strategies are the foundation for staying noteworthy in a snappy paced world," said Ed Anderson, investigate VP at Gartner. "The market for cloud organizations has created to such an extent, to the point that it is as of now an extraordinary level of total IT spending, making another period of new organizations and 'considered in the cloud' providers." In their hurry to take part in this tremendous market, sellers have rushed to tout cloud triumphs. Their locales are stacked with logical examinations

According to Anderson et al, linear programming framework has served many applications in a wide variety of production, finance, marketing, and distribution problems. The authors added that linear programming models can help managers in efficiently maximizing profits or minimizing costs when faced with constrained resource -allocation decisions.

Though the actual history of cloud computing is not that old (the first business and consumer cloud computing services websites – salesforce.com and Google, were launched in 1999), the story of cloud computing is intertwined directly with the creation of the Internet and business, the answer to the unsolved question of how internet utilization can help improve business technology was and is cloud computation. Business technology history is both extensive and interesting, almost as extensive as business itself, but the invention of computers are most responsible for the influence on business technology. Cloud computing, like all other innovation was nurtured in the right environment to take off, as multi-tenant architectures, highly

Cloud computing is an emerging Information Technology (IT) model whereby a company utilizes a pay-per-use service for it computing needs rather than maintain a local data center run by its in-house IT department. By treating computing resources as a commodity or operating expense, it allows firms to focus less on IT and more on the core elements of the operations strategy. Because of advantages like this, its popularity has grown exponentially in recent years. However, cloud computing also has certain inherent risks in its present form. This paper seeks to understand the key advantages driving businesses to adopt this computing model in ever increasing numbers,

As businesses have noticed over the last decade the initial cost of storage and bandwidth continue to diminish rapidly. As a result the offerings of Cloud-based services have become more and more attractive to businesses which are seeking to reduce their software licensing costs. It is now coming into the light that the Cloud provides businesses with cost-effective alternatives, organizations need to be cautious and not fall into the ‘all Cloud’ solution trap. We all know that there is no one-model-fits-all and rather than jumping out of the pan and into the fire into the Cloud, Organizations should investigate and plan how they can maximize the benefits of their existing set-up

Cloud computing is a shift in a new way of thinking that believes in data sharing & computations over a cloud or network of potential nodes This network consists of data centers, computers, and web services in order to make the cloud work. An application based on such clouds is taken as a cloud application. Cost Efficient: , in conjunction with the Manchester Business School and Vanson Bourne recently conducted a survey of 1,300 companies in the U.K. and U.S., supplemented by qualitative telephone interviews by the Manchester Business School with companies that used the cloud during December 2012 and January 2013.study found that 88 percent of cloud users pointed to cost savings and 56 percent of respondents agreed that cloud services have helped them boost profits.

Despite its growing importance and necessities, cloud computing has several drawbacks and disadvantages. People need to think twice when it comes to cloud computing. They need to ask themselves questions like whether it is convenient or not, whether it is right or not, whether it is safe or not. No doubt that everyone is getting into it, but still there are several factors that have to be considered like:

With the rapid development of processing and storage technologies and the success of the Internet, computing resources have become cheaper, more powerful and more ubiquitously available than ever before. This technological trend has enabled the realization of a new computing model called cloud computing, in which resources (e.g., CPU and storage) are provided as general utilities that can be leased and released by users through the Internet in an on-demand fashion. In a cloud computing environment, the traditional role of service provider is divided into two: the infrastructure providers who manage cloud platforms and lease resources according to a usage-based pricing model, and service providers, who rent resources from one or many infrastructure providers to serve the end users. The emergence of cloud computing has made a tremendous impact on the Information Technology (IT) industry over the past few years, where large companies such as Google, Amazon and Microsoft strive to provide more powerful, reliable and cost-efficient cloud platforms, and business enterprises seek to reshape their business models to gain benefit from this new paradigm. Indeed, cloud computing provides several compelling features that make it attractive to business owners, as shown below.

Capacity management and all its elements including, staff, delivery systems and processes is such a large part of any organisation it is vital to its success. For any organisation being able to manage capacity is critical to the simple business function of providing a service to meet the demand set by customers. (Hill et al, 2011)

Cloud computing have revolutionized life as we know it; it allows people to store, manage, and access their data by using a network of remote servers which are hosted on the internet rather than using a local server or own hardware. A recent study conducted by KPMG found that 81% of businesses were either evaluating cloud services, planned a cloud implementation or had already implemented a cloud strategy [1]. Organizations tend to use the cloud to reduce costs and improve efficiency. Cloud is not a commodity, some people think that it comes out of the sky, while in fact it comes from physical hardware inside brick and mortar facilities which are connected to hundreds of miles by networking cables.
