System architecture: What to consider?

Software engineering is not complete without system architecture design SteelCell. This serves as the blueprint for the whole project and the software. It defines tasks to be performed by teams of designers, while specifying hardware and/or software systems. The design of a system architecture that is effective can yield systems that will be scalable, safe and robust. Hence, the design of system architecture is a strategic process that requires planning.

Here are the 5 most important things to remember when constructing a system.

1. The Business Requirements

Understanding business requirements is the first step to creating a good system architecture. A comprehensive understanding is required to ensure successful implementation and design. An architectural style, pattern, or technology will be selected based on a clearly defined requirement set. It is important that system architects work closely together with stakeholder groups to determine their specific needs.

2. Scalability

A system’s ability to handle an increased workload is called scalability. Scalability is essential when planning a system. Vertical scalability involves increasing the system capacity by using more memory, or adding a faster processor. While horizontal scaleability involves the addition of more computers to help share the workload. In order to choose the best option for the system, you must identify what will meet your future requirements.

3. This is a good way to start.

A critical component of architecture is security. The system must be protected against unauthorised access and manipulated in unexpected ways. If you need more than one level of security to protect your data, then it is important that the systems are configured correctly.

4. Maintenance

A key aspect often ignored in the design of a systems architecture is its maintainability. Updates, bugfixes, and improvements will become necessary as systems change. Therefore, by designing with maintainability in mind from the very beginning, it is possible to reduce significantly the cost, time and effort required for these updates. Maintainability can be improved by using modularity to break down a system into easily manageable and loosely coupled components, following well-documented design standards, or implementing design patterns.

5. Testability

A good system will be easy to test. In order to do so, it is necessary that both the components of the system be independently tested as well the overall system behavior (integration test). Testing is affected by factors such as how tightly coupled components are, whether it’s possible to observe or control the system and its behavior, and even the degree of complexity.

A complex process, designing system architecture requires that you have a firm grasp of your system’s needs, be able anticipate the future and to find a balance between the competing goals. Keep these five things in mind to create a design that is efficient, secure and meets all requirements.
