The ArchiSuranceTo Go mobile consumer solution is increasingly important to ArchiSurance, which uses it to sell and renew insurance products, provide customer service, enable accurate and convenient home recordkeeping, and capture and process claims. The solution consists of three components. The Consultant lets customers review their existing coverage, and update it based on common life events, such as getting a new car, moving into a new home, or having a family member move in or out. If necessary, they can speak or chat with a customer service representative. The Home Manager helps customers photograph and catalogue their valuable possessions in order to support the filing of accurate claims in case of loss or damage. The Claim Manager enables customers to quickly file a claim for loss or damage to an insured auto, home or possession. It enables customers to describe the incident by referencing information captured with the Consultant and the Home Manager applications. In addition, it allows the customer to add photographs, audio, video and text to support a claim, submit the claim, and monitor its progress.

The ArchiSurancetoGo components rely on a number of application services hosted by ArchiSurance. The first is an Auto Identification and Description (AID) service that the Consultant uses to validate and complete auto information entered by customers. The second service, Home Identification and Description (HID) performs the same function for home information, and is used by the Home Manager. The Consultant also uses the Virtual Agent service to guide customers as they select coverage options, the Payment Processor service to arrange premium payments, and the Coverage Activator service to generate policies and put them in force.

ArchiSurance to Go also relies on a number of infrastructure services. The Home Manager uses a Multimedia Repository service to store and retrieve information about insured homes. The Claim Manager also uses this service for claim information entered by customers. All three components of ArchiSuranceTo Go use a Personal Security service to register and authenticate customers, and to manage their profiles.

Each application service is realized by an application component with the same name. Also, each infrastructure service is realized by a system software environment with the same name. ArchiSurance hosts both the application components and system software environments in a virtual ized server pool within its data center. Each service has its own virtual server. Each server is connected to a data center network (DCN) which in turn connects to a commercial wide area network (WAN).

Refer to the Scenario

The new head of IT infrastructure would like a better understanding of the applications used by ArchiSurance to Go mobile solution and the hosting infrastructure that supports these applications.

Which answer provides the best description of the applications and their underlying infrastructure? (Please note that it is not necessary to model the networks).

Scenario

Please read this scenario prior to answering the Question

The daily mutual fund trading cycle consists of four key processes: Transaction capture, pricing, trading and reconciliation. Transaction capture consists of two sub-processes: manual exchange and loans and distributions (LSD). For transaction capture, retirement plan participants use an online account management application to enter manual fund exchange transactions. For LSD, plan participants use a separate application to enter requests. The L&D application determines whether the request can be fulfilled based on the mutual fund balances held in each plan balances and a set of business rules. Each day's captured manual exchange transactions accumulate in a transaction database.

ArchiSurance contracts with a third-party information service to receive a file of mutual fund prices at the close of each trading day.

The pricing application uses this file to convert captured transaction into trades, and then validates each trade against the mutual fund balances held in each plan. The pricing generates a trade file with the minimum number of trades necessary. The trading application sends this file to an external trading service. When the trading application receives a confirmation file back from the trading service, it passes it to the reconciliation application, which updates the plan recordkeeping database.

The account management and LSD applications are hosted on separate application server clusters. Each cluster is a physically separate host that runs application server software on a set of virtualized hosts. All of these applications use a database server infrastructure that is hosted on another separate cluster of virtualized servers also on a dedicated physical host. The pricing, consolidation, trading and reconciliation applications, however, are batch applications that run on the ArchiSurance mainframe computer. All application hosts are connected via a converged data center network (DCN), which also connects them to a storage area network (SAN) as well as a wide area network (WAN) that is used to communicate with the external trading service. The SANincludes two physically separate storage arrays, ere of which holds data for all databases, and another that holds data for all files.

Refer to the Scenario

You have been asked by a team of IT auditors to show the applications used for daily trading and the infrastructure that underlies them, including all ArchiSurance servers, storage arrays and networks. It is not necessary to model the WAN or other external infrastructure.

Which answer best describes the applications and infrastructure?

Scenario

ArchiSurance senior management; board members, customers and major stockholders have long been concerned about disaster resiliency in light of the company's heavy reliance on a single data center. The data center is located in an area that is prone to flooding and earthquakes, according to expert assessments done by consultants retained for this purpose. In addition, the data center is located under a busy cafeteria, and water occasionally leaks through its ceiling.

To address these problems, ArchiSurance has developed a plan to move from its current data center to a pair of ready-to-use data centers in separate cities. The data center move is designed to reduce the risk of business interruption, reduce both planned and unplanned downtime for critical applications, and reassure ArchiSurance stakeholders. However, a number of limitations make the planned transition to the new data centers particularly challenging. A number of critical ArchiSurance applications cannot be offline for more than an hour, and any downtime for these application must only occur in certain four-hour windows each weekend. Also, the move cannot occur during quarterly or year-end closing periods in order to avoid interrupting critical processing. Fulfillment of these specific type of requirements will reduce the risk of business interruption from the data center move activities themselves.

ArchiSurance management has therefore planned a multi-phase data center transformation program. All of the activities in each phase are necessary to ensure a progression of stable and fully functional data center configurations. The first phase consists of detailed scheduling and planning to produce a comprehensive transformation plan that meets ArchiSurance timing and scheduling requirements. During the second phase, ArchiSurance is to contract for the hardware and software required for the new datacenters, as well for refunds for the hardware and software to be returned from the current data center once it is shut down. During the third phase, the new data centers are to be set up, and the new hardware and software are to be tested in parallel with what is already in production. The actual transition between the old and new data centers occurs in the fourth phase, and the fifth phase involves shutting down and dismantling the old data center, and returning its hardware and software for contracted refunds. Phases two through five are each to be initiated when specific conditions are met in the previous phase.

Refer to the Scenario

The head of IT has asked you to help her explain why ArchiSurance decided to transform its data center infrastructure. You must model the stakeholders, the motivations, and the influencing relationships between these motivations. You must also model the specific goals realized by the data center transformation program and the limitations within which this program must operate.
