Briefly, functional requirements define what a system is supposed to do, like in the case of a car, take a person from A to B, and non-functional requirements stipulate how a system is supposed to be.
Architecture characteristics covers most of the aspect of a large-scale project:
The ability for the system to perform and operate as the number of users or requests increases. Scalability is achievable with Horizontal or vertical scaling of the machine.
It is measured as a percentage of uptime and defines the proportion of time that a system is functional and working. Availability is affected by system errors, infrastructure problems, malicious attacks and system load.
Extensibility measures the ability to extend a system and the effort required to implement the extension. The extension can be through adding new functionality or modifying existing functionality. The principle provides for enhancements without impairing current system functions.
Consistency guarantees that every read returns the most recent write. This means that after the execution of every operation, the data is consistent across all the nodes, and thus all clients see the same data at the same time, no matter which node they connect to.
A system can gracefully handle and recover from accidental and malicious failures. Detecting failures and recovering quickly and efficiently is necessary to maintain resiliency.
Usability can be described as the capacity of a system to provide a condition for its users to perform the tasks safely, effectively, and efficiently while enjoying the experience.
Observability is the ability to collect data about program execution, internal states of modules, and communication between components. To improve observability, use various logging and tracing techniques and tools.
Degree the software protects information and data so that people or other products or systems have the degree of data access appropriate to their types and levels of authorization. This family of characteristics includes confidentiality, integrity, nonrepudiation, accountability, and authenticity.
Durability is the solution ability of software’s serviceability and meet users’ needs for a relatively long time.
It has become today’s buzzword when describing a contemporary software method. An associate agile team could be a handy team able to befitting reply to changes. Modification is what software development is highly abundant.
