The ArchiSurance enterprise document management infrastructure provides critical support for myriad types of documents and document-based transactions, many of which are executed in high volume each day. At the core of the infrastructure is the document management systems software, which has three major modules: a document engine that stores, retrieves and performs a variety of operations on documents, a workflow engine that hosts document management applications, and an application engine, which hosts the most sophisticated applications. The application engine invokes the document and workflow engines as necessary when hosting application components that require their services.

The claim management application component is critical to ArchiSurance business operations. It is hosted by the application engine, and launches whenever an individual files a new claim. The claim management component requires different documents to demonstrate proof of loss depending on the type of claim filed, the type of insurance that is in force, and various other circumstances. When the correct documents are filed and verified by an intake operator, proof of loss is complete, and the claim management component assigns the claim to a claim analyst by reading and updating analyst status data and applying business rules stored as data.

Due to its business-critical nature, the document management solution is hosted redundantly at two geographically separate data center sites known as Site A and Site B. Both sites provide identical infrastructure. Each site contains a highly available data center network (DCN) that is connected to the highly available ArchiSurance wide area network (WAN). Each claim management server is connected to its site DCN, and each DCN is a converged network that connects both servers and storage arrays, including a physical storage array dedicated to the claim management application. Each site contains four high-powered separate physical serversrules stored as data.

Each claim management server is connected to its site DCN, and each DCN is a converged network that connects both servers and storage arrays, including a physical storage array dedicated to the claim management application. Each site contains four high-powered separate physical servers dedicated to the claim management application. At any one time, one server is on standby while the other three servers are, respectively, hosting the document, workflow and application engines. Each active server provides a monitoring service that is In constant two-way communication with the monitoring service on the standby server. If a server fails, the surviving monitoring services perform a failover sequence to assume failed server's workload if it was active. The surviving monitoring services also alert the operations team on duty.

Refer to the Scenario

A new IT manager has asked you to model the infrastructure hardware and networks that supports document management, including the data center sites, servers, storage, and networks as well as the services necessary for automated failover within a server cluster. Since the two data centers provide identical document management infrastructure, for Site B it is only necessary to show the associated networking.

The ArchiSurance IT Operations (IT Ops) department has five core responsibilities, and continuously executes a core business process for each responsibility. (1) The Batch Ops process makes sure that batch jobs execute completely, successfully, and on time, consistent with their service level agreements (SLAs). (2) The Online Ops process makes sure that all web applications and content delivery services are available and performing according to their SLAs. (3) The Security Ops process protects ArchiSurance IT operations from being damaged by malicious or careless incidents. (4)The User Support process assists users of ArchiSurance systems with problems or requests. (5) The Continuous Improvement process monitors and measures the performance of each of the other processes and works to solve problems and optimize use of ArchiSurance resources. In order to enable monitoring, each of the other processes generates monitoring data that is read by the Continuous Improvement process.

The processes in the System Ops category, which are Batch Ops, Online Ops and Security Qds, each have a separate sub-process for incident management. These sub-processes are triggered, respectively, by Batch, Online and Security Incidents. One of the first steps in each incident management sub-process, is to pass an Incident Alert to each of the other System Ops processes. This is accomplished by posting the alert to the Alert Buffer.

The Batch Ops process uses a schedule that lists all batch jobs and their dependencies. The schedule is used by two Batch Ops sub-processes. The Batch Planning sub-process updates this schedule for use by the Execution Management sub-process.

The Batch Ops process uses a number of applications that interact with each other. The Batch Scheduler application enables users to manage a database of jobs, job schedules and dependencies, and launches batch jobs according to the database. The Batch Monitor application uses the job schedules as a reference to monitor job execution, and reports all exceptional conditions to the both the Batch Scheduler and the Incident Handler applications via the Alert Buffer described earlier in the scenario. The Incident Handlerrefers to a set of business rules to determine the systems and individuals that must be notified of each incident. Based on these determinations, the Incident Handler produces appropriate notifications.

Due to their criticality, the Batch Scheduler, Batch Monitor and Incident Handler applications are hosted redundantly in multiple geographically distributed data centers. In each data center, the three applications are hosted on a fully redundant virtual server cluster. Each cluster is connected to two site local area networks, each of which connects to a separate physical storage array.

Independent insurance brokers that work with ArchiSurance have complained of difficulty in communicating with salespeople and other personnel at ArchiSurance. They have said that email is too clumsy and slow for working on urgent deals, people do not always answer their mobile phones, and it is difficult to tell whether an individual is available. They have also complained that it is too time-consuming for them to manage their commission payments using an older web application that requires them to print out and mail forms for making some routine changes, and also does not work on many mobile devices. Some brokers have said that it is easier to do business with ArchiSurancecompetitors that provide easy-to-use mobile applications for both general communication and commission management. In fact, the ArchiSurance Vice President of Sales and Chief Marketing Officer have both expressed concern about reports from the ArchiSurance market research department that the company is gradually losing market share with some of the same brokers that have been complaining. These executives are also concerned that ArchiSurance may not meet the targets for revenue growth.

Upon hearing about these issues, the ArchiSurance Chief Information Officer (CIO) hired a consultant to design a new mobile infrastructure for broker interaction. This infrastructure is required to enable easier communication with ArchiSurance brokers in order to help the company increase its market share with each of them and consequently attain its targets for revenue growth. In order to ensure that the new infrastructure would meet these goals, the CIO told the consultant that the new infrastructure must make it easy for ArchiSurance to develop and deploy applications and content for its brokers. It must provide federated authentication and an encrypted communication channel as well as instant messaging and presence services.

The new mobile broker interaction infrastructure architecture includes a number of system software components. A secure reverse proxy authenticates users and provides an encrypted channel to communicate with them. The proxy uses a service provided by directory server software to authenticate users. The directory server communicates with the ArchiSurance federation server, which in turn communicates with peer federation servers hosted by trusted brokerage organizations. Once the user is authenticated, the ArchiSurance broker portal uses the ArchiSurance web content management system to assemble authorized and relevant content for each broker. In order to provide presence services, a unified communications (UC) server exchanges information with the directory server and an instant messaging server.

All of these components are hosted on a single physical hardware platform hosting a virtualized server infrastructure. The server infrastructure is connected to a converged local area network (LAN), which is also connected to a commercial wide area network (WAN) over which ArchiSurance communicates with its brokers.

Refer to the Scenario

The head of IT infrastructure engineering has asked you to model the ArchiSurance infrastructure for broker interaction. You must show the system software, network and server components and the flows between them. You must also show the services that the system software components provide. It is not necessary to model the wide area network (WAN) or the components hosted by ArchiSurance brokers.
