An Nginx architect argued that the relevance of the Twelve-Factor app concept is somewhat specific to Heroku, while introducing their own (Nginx's) proposed architecture for microservices. [3] The twelve factors are however cited as a baseline from which to adapt or extend.
It is common for microservices architectures to be adopted for cloud-native applications, serverless computing, and applications using lightweight container deployment. . According to Fowler, because of the large number (when compared to monolithic application implementations) of services, decentralized continuous delivery and DevOps with holistic service monitoring are necessary to ...
Microservices are often used when architecting for continuous delivery. [12] The use of Microservices can increase a software system's deployability and modifiability. The observed deployability improvements include: deployment independence, shorter deployment time, simpler deployment procedures, and zero downtime deployment.
The PHP Standard Recommendation (PSR) is a PHP specification published by the PHP Framework Interop Group. Similar to Java Specification Request for Java, it serves the standardization of programming concepts in PHP. The aim is to enable interoperability of components and to provide a common technical basis for implementation of proven concepts ...
Domain-driven design (DDD) is a major software design approach, [1] focusing on modeling software to match a domain according to input from that domain's experts. [2] DDD is against the idea of having a single unified model; instead it divides a large system into bounded contexts, each of which have their own model.
In an environment in which data-centric microservices provide the functionality, and where the microservices can have multiple instances, continuous deployment consists of instantiating the new version of a microservice and retiring the old version once it has drained all the requests in flight. [7] [8] [9]
Software modernization [12] is a risky, difficult, long, and highly intellectual process involving multiple stakeholders. The software modernization tasks are supported by various tools related to Model-driven architecture from the Object Management Group and processes such as ISO/IEC 14764:2006 or Service-Oriented Migration and Reuse Technique ...
A deployment diagram [1] "specifies constructs that can be used to define the execution architecture of systems and the assignment of software artifacts to system elements." [1] To describe a web site, for example, a deployment diagram would show what hardware components ("nodes") exist (e.g., a web server, an application server, and a database server), what software components ("artifacts ...
