April F_IT401_IP2.doc.docx

Distributed systems are particularly vulnerable to security threats because they are exposed in many areas over networks. Also, distributed systems are often business-critical applications that must not be compromised.

For this assignment, you will identify the security risks that may be present for your distributed system project. You will also modify the consultant’s analysis report to address any new issues you discover.

The following are the project deliverables:

  • Update the Consultant’s Analysis Report document title page with new date and project name.
  • Update the previously completed sections based on your instructor's feedback.
  • Include the following new content:
    • Security
      • Identify the primary security risks your distributed system might face.
      • Determine the threat level in terms of likelihood and impact on the business.
      • Based on the likelihood and impact of the security threats, determine the order in which threats should be addressed, and prepare an action plan to reduce the threat from each risk listed in priority order.
  • Be sure to update your table of contents before submission.
  • Name the document yourname_IT401_IP4.doc.

Definition of Architecture(Terms) In order to understand architecture system, we have to look on couple of architectural-related definitions Architectural is the one whose responsibility is designing of architecture and the creation of an architectural description. Architectural artifact is a certain document, report or model that contributes greatly to architectural description. Architectural framework is a typical skeletal structure that describes architectural artifacts. Architectural methodology is a general term that defines a structured approach in solving problem related to architecture. Architectural process is a collective series of actions that relate to the goal of producing architecture. Three Types of Architectures 1. Database Architecture This is database where data encoded in it are organized into the logical components that are visible to users. The database is physically implemented in more than one file on a disk. One works solely with logical components such as tables, views, procedures and users when using database. In database architecture, the physical implementation of files is largely transparent. However, database administrator is only one that works with the physical implementation. 3 Running Head: SYSTEM ARCHITECTURE In every instance of SQL Server has four system databases and two or more user databases. Some organizations, however, have only one database that contains the full of data for their organization others has different databases for each group in their organization. An organization, for instance, may have one database for sales, one for payroll and one for document management (Ho, 2010). 2. Business Architecture The business architecture comprises an enterprise architecture that relates to corporate business, documents and diagrams, of which defines the business architectural structure. In this case, business architects are those experts who build architecture. It can be used to refer to an architectural organization of an enterprise or a business unit. Essentially, business architecture bridges between business model and enterprise strategy on one side and business functionality on the other side (Gharajedaghi, 2011). 3. Solution Architect Solution Architect has a deep meaning concerning problem solution in information technology. it is often used as technical architecture domain. In it functions, Solution Architecture structures solution architecture descriptions across different domains and industries. It effectively acts as a monitor and administer in every implementation. The solution architect requires deep and wide knowledge and skills. Therefore, to enhancing effectiveness, solution architect need to have experience on multiple hardware and software environment (Adil, 2009). This will enhance flexibility when dealing with heterogeneous environments. This architecture involves in organizing the development effort relating to systems solution. All the overall vision that relates to the project solution in question is developed by solution architecture. 4 Running Head: SYSTEM ARCHITECTURE The Solution Architecture as Appropriate architecture Business Architecture The business architecture will be appropriate for my outlined project (Vehicle Dealers Business). This is the best architecture since it articulates functional structure of an enterprise in regard to its business terms and information. It is such effective that it sets business capability models. It can successfully perform specific business functionality and hence delivers business results according to prescribed circumstances. Business architecture formulates all internal and external actors, which ensure that flowing in and out of the enterprise. Therefore, it will be best for my project since it be capturing the strategic goals that can effectively drive my company forward (Business Strategy view). In addition, it will be describing my business functionality and services. Again, it is the best architecture in establishing my business shared semantic such as orders, customers and suppliers (Business Knowledge). These semantics are such important since they form an effective vocabulary that any company can rely upon for its business communication (Gharajedaghi, 2011). Conclusion Considering all the above three architectures, business architecture will be a good and effective disciplined approach in realization of my business models and in serving as business foundation of the business. This will successfully enhance accountability and strategic decision-making. This architecture values proposition hence increases functionalities through mapping the business’ vision and goals. 5 Running Head: SYSTEM ARCHITECTURE References Gharajedaghi, J. (2011).
