Architecture assessments provide an essential tool to reduce risk, increase decision quality and ensure successful architecture delivery.
Competency is the knowledge, skills and ability of an architect to deliver value within the purpose of the profession.
The Circuit Breaker pattern is used to check the availability of an external service, detect failures and prevent them from happening constantly. For example, if an application needs to retrieve data from an external service 100 times per second, and the service is unavailable (e.g., down for maintain ace or because of a hardware failure),
There are some consideration when using retry pattern: When there is an indication that the fault is not transient or unlikely for service request to be successful if repeated (for example, an authentication failure caused by invalid user credentials or bad request send to service , e.g., HTTP status code 4xx received from the service), the application should not try to retry , but abort the operation invocation and report a suitable exception. If the specific fault is unusual or rare, it may have been caused by extraordinary circumstances such as a network packet lost in transit. In this case, the application could immediately retry the same request again because the same failure is unlikely to happen again and the request will probably be successful. If the fault is caused by issues such as service being not fully responsive (e.g., “service busy “) the service consumer should wait for a suitable time before retrying the request.
The first installment of modern patterns with basic descriptions. A part of the collection of modern architecture patterns for the ITABoK.
Technical debt is a critical issue for all architects and developers of software intensive systems. Learn techniques for dealing with it.
The architecture lifecycle, or Architecture Development Life Cycle (ADLC), are the stages that an architecture goes through from its inception to its decommissioning. The ADLC provides a guiding process for developing architecture, and helps the architect understand and communicate the state of the architecture.
