Please help out. This needs to be broken down in two answers since they are two questions. A total of 1,500 words or more are needed. This also needs to have 5 credible sources and they need to be cited.

thank you in advance for the help

Group Case Study \#4 (Chapter 4 ) Facebook Building Efficient, Reliable Data Centers Facebook is a social networking Web site and service where users can post comments, share photographs and links to news or other interesting content on the Web, play games, chat live, and even stream live video. As of June 2017. Facebook had 2 billion monthly active users and this number is increasing at a rate of 17 percent per year. Two of its other apps, Facebook Messenger and WhatsApp, have over 1.2 billion active users. All these users require lots and lots of computing capacity to meet their data processing needs and huge amounts of data storage to hold all their data, photos, and videos. For example, just to load a user's home page can require pulling data from hundreds of servers, processing tens of thousands of individual pieces of data, and delivering the selected data in less than one second. With more people going live and sharing video, Facebook must continually add new data centers to keep up with the demand. Facebook spent $2.5 billion on data centers, servers, network infrastructure, and office buildings in 2015. Facebook already has existing data centers in Prineville, Oregon; Forest City, North Carolina, Lulea, Sweden; and Altoona, Iowa. Additional data centers are being built or planned for Fort Worth, Texas; Clonee, Ireland; Los Lunas, New Mexico; Papillon, Nebraska; New Albany, Ohio; Ashburn, Virginia, and Odense, Denmark. These data centers are large football field-sized buildings each housing tens of thousands of servers all networked together and to the outside world. Building and outfitting each data center is a major project typically lasting 12 months or more and costing over $500 million. A small group of Facebook engineers spent two years designing and building Facebook's first data center in Prineville including software, servers, racks, power supplies, and cooling. When completed, the data center was 38 percent more energy efficient to build and 24 percent less expensive to run than the data centers Facebook rented from other organizations. Facebook uses servers powered by chips from both Intel and AMD with custom designed motherboards and chassis. It has also investigated energy efficient ARM-powered servers. Facebook hardware engineers remove everything from the servers that is not necessary for example no bezels, no paints, no extra expansion slots, no mounting screws. The servers are mounted into a rack which holds 90 servers in three columns. Cabling and power supplies are moved to the front of the servers so Facebook technicians can work on the equipment from the cold aisle, rather than the enclosed, 100 degree plus hot backside cold aisle, rather than the enclosed, 100 degree plus hot backside of the server. The servers are outfitted with custom power supplies that enable them to take power directly from the source eliminating the need for step-down units as power passes through the UPS systems and power distribution units. In the event of a power outage, the batteries keep the servers running until the building's backup generators can kick on. The rest of this page is left intentionally blank In April 2011, Facebook, together with Intel, Rackspace, Goldman Sachs, and Andy Bechtolsheim (billionaire co-founder of both Artista Networks and Sun Microsystems), launched the Open Compute Project Foundation. The Foundation is targeted at redesigning hardware to support the increasing demands of users for more efficient, flexible, and scalable hardware and data centers. This is made possible by the sharing of details of its energy efficient data center design, as well as custom designs for servers, network switches, power supplies, and UPS units. This approach marks a radical departure from industry practice which typically regards such information as intellectual property to be tightly protected. The Open Compute servers represent a significant improvement in energy efficiency and a substantial reduction in server cost. Group Case Study \#4 Questions - Answer Both 1. Identify three good reasons why a Tier 2 data center would not meet Facebook's needs. 2. Your organization has decided to outsource its data center operations. You are responsible for performing an initial assessment of service organizations that wish to compete for this business. Develop a set of six questions you can use to determine if an organization's data center is a 1,2,3, or 4 data center. 1. You will want to pay attention to such items as the Sources criteria requiring you to incorporate at least five (5) credible sources (peer-review journal articles, scholarly books, authoritative websites)
