Online System architecture homework help
System architecture is abstract conceptualization-oriented, global, and focused to achieve the mission and life cycle concepts of the system.it also focuses on high-level structure in systems and system elements. It addresses architectural principles concepts, properties, and characteristics of system-of-interest. It may also be applied more than one system, in some cases forming the common structure, pattern, and set of requirements for classes or families or related systems. System architecture assignments are challenging to most students all over the clobe. But with our writers specializing in this course find it easy. That’s why we are the best for your system architecture assignments.
The purpose of system architecture activities is to define comprehensive solution based on principles, concepts, and properties logically related to and consistent with each other. Architectural patterns are a method of arranging blocks of functionality. They can be used at the subsystem or enterprise level.
What is system architecting in system architecture
System architecting is simply the process of creating system architecture, which we regard as process within system engineering. It may be motivated by a variety of factors. For example, forward architecting aims to provide a basis for more detailed design while ‘reverse architecting’ captures an existing system architecture for analysis.
Architecting can be more or less systematic but typically involves: understanding context, exploration of alternatives understanding trades, supporting decision making and so on. There are many good guiding principles for architecting including modularity, high cohesion, loose coupling etc.
Architecture description of a system
An architecture framework contains standardized viewpoints, view templates, meta-models, model templates, etc. that facilitate the development of the views of system architecture. Specifies the normative features of architecture framework, viewpoints, and views as the pertain to architecture description. A viewpoint addresses a particular stakeholder concern. The viewpoint specifies the kinds of model to be used in developing a system architecture to address to that concern, the ways in which the models should be generated and how the models are related and use to compose a view.
System architecture best practice
- Confirm the purpose before architecting
- Make sure that the stakeholders have an opportunity to vet architectural trade-offs as they occur
- Evaluate the architecture throughout system development. Although an architecture is intended to be persistent framework during the life cycle of a system, unforeseen changes can be influencing the best of “first version” architectures.
- Construct the architecture to help understand technology readiness and evolution and avoid getting locked in proprietary potentially obsolete technologies capture by specific vendor
Types of system architecture
Integrated System architecture-orchestration, computing, storage and networking are tightly integrated in single box. System upgrade growth upgrade and growth is through replacement of entire system. The architecture is designed for specific workload
Distributed system architecture-Computing and storage are separate system blocks orchestrated separately and connected through networks. System upgrade is through replacing components blocks. System growth is through adding blocks. The architecture is designed to enable growth and scale out multiple workloads.
Pooled system architecture –computing storage and networks are in separate resource pools consisting of blocks and orchestrated separately. System upgrade is through replacing blocks within a pool. System growth through adding blocks to a pool. The architecture is designed to enable efficient scaling and growth of multiple workloads.
Converged-Storage, computing and networks are separate resource jointly orchestrated and in a single chassis. System upgrade is through swapping components within the chassis. System growth is through adding components ton empty chassis slots. The architecture is designed to support rapid deployment of many workloads. Within converged infrastructure the pendulum swings back to integrated system architecture with vendors also offering fit for specific workloads.
Activities of the process of system architecture
- Initialize the definition of the system architecture-Building an understanding of the environment/context of use for which system is needed in order to establish insight into the stakeholder concerns. To do this analyse relevant markets, industry, stakeholder, enterprise, business, operations, mission, legal and other information to help understand perspectives
- Define necessary architecture viewpoints-Base on identified stakeholder concerns, identify relevant architecture viewpoints and architecture framework that may support the development of models and views.
- Develop candidate architectures models and views-Using relevant modelling techniques and tools in conjunction with stakeholder needs and requirements process and the system requirement process, determine the system-of interest context including boundary with elements of the external environment. Define the architectural entities. Relate architectural entities to concepts, properties, characteristics, behaviours, functions, and constraints are to decisions of the system of interest architecture. Check models and view consistency and resolve identified issues. Verify and validate the models by executions or simulation, if modelling techniques and tools permit. Where possible, or use executable architecture prototypes or simulators.
- Relate system architecture to system design-Define the system elements that reflect the architectural characteristics the architecture is intended to be design-agnostics, these systems elements maybe notional until the design evolves. Define interface for those that are necessary for the level of detail and understanding of architecture.
- Asses architecture candidates and select one-Asses the candidate architecture using architecture evaluation criteria. This is don through application n of system analysis, measurement, and Risk management processes. Select the preferred architecture. Determine design properties applicable to system elements in order to satisfy the architectural characteristics.
- Manage the selected architecture-Establish and maintain the rationale for all selections among alternatives and decision for the architecture frameworks, viewpoint kinds of models and views. establish a means for governance of architecture.
Purpose of system architecting process in system architecture.
Every business exceeding a few people enables the efficient concurrent work of dividing the tasks I’m smaller more specialized jobs, the decomposition principles in action. This decomposition of responsibilities requires an opposing force integrating the activities in useful overall business result. The system architecting process is responsible for:
- The integral technical aspects of the product creation process, from requirements to deployment.
- The integral technical vision and synergy in the policy and planning process.
The system architecting process is striving for an optional overall business result by creating and maintain the key issues, such as balanced and consistent design, selection of the least complex solution, and satisfaction of the stakeholders
The system architecture process is balancing among others:
- External requirements and internal requirements
- Short term needs and long-term interests
- Efforts and risks are requirements to verification
- Mutual influence of detailed designs
- Values and costs.
It is the purpose of the system architecting process to maintain the consistency throughout the entire system, from roadmap and requirement to implementation and verification
System architecture enables factor for an optimal result is simplicity of all technical aspects any unnecessary complexity is a risk for the final result and lowers the overall efficiency
