This in turn makes IT a more strategic asset for successfully implementing a modern business strategy. As well, each of them takes decades and decades of information structure and put it to use. 1.

Service-oriented architecture. ISA 101.U05.01 Describe the reasons why Enterprise Architecture (EA) is critical to the successful acquisition of DoD IT/SW systems.

Collecting, storing, and organizing these data can be easily done using Enterprise applications. This section expands on the Cisco Service-Oriented Network Architecture (SONA) framework described in Chapter 2 and explores the six modules of the Cisco Enterprise Architecture, with an emphasis on the network infrastructure design considerations. As an example, when developing computer network architecture, a top-down approach from contextual to component layers can be defined using those principles and processes (figure 4). a) enterprise architecture exists to optimize and align IT resources with business goals/objectives, b) enterprise architecture is manifested as a set of inter-related models, and c) these models are characterized using a prescriptive metamodel, such as Zachman’s original work or one of CISR’s four operating modelsv. The Open Group Architectural Framework. Using architecture as a metaphor presupposes that there is some-thing that shows similarity to the proper use of the term. Fortunately, a better architectural pattern exists for enterprise system integration — called service-oriented architecture (SOA). But identifying that similarity was and remains an issue: many different things are all referring to the same term. 2. However, EA frameworks are no more than typical management fads with the long history of unsuccessful implementations 1, 2 and successful EA practices do not resemble the recommendations of these EA frameworks in any real … Managing the employees’ database is one of the worst nightmares for any organization. Benefits of enterprise architecture. As an added security measure, with most cloud-based services, different security settings can be set based on the user. These are scalability, ease of management, flexibility, and security. Exceptions to the enterprise architecture might be supported for specific cases if there is a consensus that the benefits of using a solution from a specific technology exceed those arising from the adoption of the enterprise architecture. Yet over the past two decades, enterprise architecture (EA) has gradually emerged to help institutions in many markets build new operating … Convergence offers several advantages: - that exist both within the enterprise and in the IT industry at large, which the enterprise considers itself to have available for the development of architectures. Each of them has strengths and weaknesses. Examples of Operational Efficiency benefits would be using the EA to identify and eliminate complex, costly processes between incongruent systems, or perhaps using the EA to standardize technology platforms and propagate identified best practices, to simplify training, maintenance and support requirements. The processes are dependent on a set of common master data that are used … Enterprise systems make it easy to generate detailed reports with statistics, graphics and calculations that managers can use to track performance and spot potential problems.

So here are 15 benefits of software architecture that will tell you more about how it can help you in your project and why you should invest in a good software architecture. Integration, interoperability, data quality, process automation analytics -- these ideas are simple to describe but can be quite hard to execute in today's business environments.

By using encryption, information is less accessible by hackers or anyone not authorized to view your data. This is not to say that it has no value: EA can pay huge dividends to the few organizations that are able to get it right. Using a Modular Approach to Network Design. Deployment As services are separately deployed, they allow for extreme scalability and reliability.
