The Effects Of Server Farms

event of a catastrophic disruption (fire) or disaster (hurricane) and a major IT or data center outage occurs

The risk-management plan then starts by identifying each of these sources, their magnitude, their relation to the various design stages, and their possible effects on cost, schedule, quality, and performance. The next step is to look for modifications or alternatives that would permit risk reduction. The thoughtful selection of computer language or operating system may reduce some of the integration risks. If management decides to develop a new software package, contingency plans that cut expenses and development time at the cost of lower performance should be prepared. These plans are used in case the undesired event takes place. By preparing a contingency plan in advance, time is

Instead of having one physical piece of hardware that could fail, setup virtualization with redundancy. Virtualization platforms today have the ability to shift

Virtual Machine Security - Full Virtualization and Para Virtualization are two kinds of virtualization in a cloud computing paradigm. In full virtualization, entire hardware architecture is replicated virtually. However, in para virtualization, an operating system is modified so that it can be run concurrently with other operating systems. VMM Instance Isolation ensures that different instances running on the same physical machine are isolated from each other. However, current VMMs do not offer perfect isolation. Many bugs have been found in all popular VMMs that allow escaping from VM (Virtual machine). Vulnerabilities have been found in all virtualization software, which can be exploited by malicious users to bypass certain security restrictions or/and gain escalated privileges. ation software running on or being developed for cloud computing platforms presents different security challenges. It is depending on the delivery model of that particular platform. Flexibility, openness and public availability of cloud infrastructure are threats for application security. The existing vulnerabilities like Presence of trap doors, overflow problems, poor quality code etc. are threats for various attacks. Multi-tenant environment of cloud platforms, the lack of direct control over the environment, and access to data by the cloud platform vendor; are the key issues for using a cloud application. Preserving integrity of applications being executed in remote machines is an open

It is important to have information gathering techniques so that no information can be overlooked. The information system that we are looking for must meet the requirements of the organization and the employees that will be using the system. The first part of information gathering should consist of identifying information sources. The main sources of information in the company should be employees who use the system and will be using the new one because they can tell you what works and what does not work or basically what’s good about this system so that we can implement it in the new

The information for sizing the server infrastructure is gathered from existing server utilization for the applications supported. The amount of servers selected for implementing the environment is based on projected cpu and memory needs to support the users. As part of projecting resource needs, allowances are made for variances in versions of system hardware.

9. When assessing the risk impact a threat or vulnerability has on your application and infrastructure, why must you align this assessment with both a server and application software vulnerability assessment and remediation plan? Because they may coincide with each other which

As we all know virtualization is the requirement of future. We have evolved from the age of traditional environment to virtual environment.We have grown accustomed to almost all things virtual from virtual memory to virtual networks to virtual storage.The most widely leveraged benefit of virtualization technology is server consolidation, enabling one server to take on the workloads of multiple servers. For example, by consolidating a branch office’s print server, fax server, exchange server, and web server on a single windows server, businesses reduce the costs of hardware, maintenance, and staffing.

Teresa was a senior systems analyst in the IT department in a city 500 miles away from your office. She just finished an analysis of virtualization of server resources for her office, which has

Compared to commodity servers, mainframe transaction processing is scalable because many businesses experience massive increases in computational loads (Hallman, 2015). Let us consider this circumstance: During a retail store front’s hours of operation, there may be many customers making product purchases. Simultaneously, there may be many customers seeking refunds on their product purchases. One can also consider that this retail store front offers its services over the Internet with the use of an e-commerce operation called metrics management. This e-commerce operation encompasses web analytics, channel metrics, financial metrics, and product metrics. With the use of metrics management, one can measure the effectiveness of the Internet channel and the retail store front channel by analyzing the quantity of product purchases and product refunds to deduce which channel promotes a financially effective service; or, one could objectively consider to have these channels work in tandem to capture a product purchase in any way possible. In this circumstance, the quantity of product purchases and product refunds are metrics that require computational loads because the mainframe would store and

According to McGonigle and Garver (2012), “data are discreate entities described objectively without interpertation” ( p. 97). The fist step in the plan is to gather data from the internet databases and related books and journals. This data obtained will not be interpreted but will be group together inorder to continue to the second step of the plan; obtaining relevant information about my research question. “ Information is data that are interpreted, organized, or structured” (McGonigle & Garver, 2012, p.97). This step requires precise interpretation and analization of the data was obtained. The information will be organized and structured into each of the PICO variables. McGonigle and Garver (2012), describe knowledge as “information that is synthezized so that relationships are identified and formalized” (p.97). It is important to use this concept when making the decisions of which of the information will be used and what the potential outcomes of the information chosen will have on my reasearch question; will it favor the topic or will it unfavor it? The final concept of the plan is the use of wisdom. “Wisdom focuses on the appropriate application of knwledge” (McGonigle & Garver, 2012, p.99). The use of wisdom guides the decisions about what would be the most appropriate use of

Finally, the server is responsible for handling mixture of different task, such as accessing and updating the database, running web components of the project (server to handle multiple clients in multi-player games) and hosting a web site. These tasks rely heavily on CPU, RAM, HDD. It is worth to note that the specifications of a server are dependent on how many users are going to connect to the server and what purpose it is going to serve.

When servers were pushed to their limits the initial thought process was to beef up the system such as adding more ram, upping the processor, and increasing the storage space. However these measure only took the scaling so far. At some point, you would have again maxed out all the hardware platform and its capability. Also beefing up the server meant substantial down time and in the exploding world of commerce that was not a viable option.

Most of the manufacturing in the organization is automated with the help of high end servers. These physical servers when are overloaded or when they are being used for longer period of time, tend to degrade and malfunction as their components start to fail and this would require replacing them with new ones. This will incur additional cost to the company if the server is not covered under manufacturer warranty or it has expired and is no longer in support by the manufacturer. Thus the organization is in need of virtualization of the physical servers to overcome these problems. The organization has been around for more than three decades and hence is using older applications that won’t run on newer hardware and the current hardware is about to degrade. So in order to save the company from such incidents that could result in major setback in manufacturing, virtualization of these servers is necessary. Another benefit of virtualizing the servers is that the resources such as CPUs, disk size, RAM size of the virtual servers can be increased if the load is too high on the server. This can be done on the fly, without creating an impact to the organization.

In just the first decade of the 21st century, exponential advancements have been made in the field of science and technology. Computing capabilities have grown multifold and we are now consuming information in measures of exabytes, which could soon cross over into zettabytes. In fact, it was estimated in 2011 that all of the computers in the world collectively crunched 9.57 zettabytes (Turnbull, 2011). All this information has created a dependency on machines to deliver results in the fastest possible time, so that decisions can be made and actions can be taken at the earliest. This could be right from something as simple as an Excel sheet used for maintaining the finances of a household, to the computers that power Dow Jones. As can be imagined, any occurrences of failures can prove to be catastrophic, as was evidenced earlier this year. On the 8th of July, the servers at the New York Stock Exchange went down for over four hours, thus sending thousands of investors into a tizzy (Popper, 2015). Around the same time, United Airlines suffered a network issue that directly resulted in the cancellation of 61 flights and the delay of over 1,100 flights (Drew, 2015). As evidenced by these examples, no system is foolproof and therefore, it would be prudent for those who are in charge to develop plans to fall back on in case of such failures. To be able to tackle such issues, risk management programs are formulated. These programs try to offer comprehensive coverage of
