Flask is a micro web framework written in Python.It is classified as a microframework because it does not require particular tools or libraries. [2] It has no database abstraction layer, form validation, or any other components where pre-existing third-party libraries provide common functions.
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 ...
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.
There is no single commonly agreed definition of microservices. The following characteristics and principles can be found in the literature: fine-grained interfaces (to independently deployable services), business-driven development (e.g. domain-driven design), IDEAL cloud application architectures, polyglot programming and persistence,
In 2003, Python web frameworks were typically written against only CGI, FastCGI, mod_python, or some other custom API of a specific web server. [6] To quote PEP 333: Python currently boasts a wide variety of web application frameworks, such as Zope, Quixote, Webware, SkunkWeb, PSO, and Twisted Web -- to name just a few.
An application server is a server that hosts applications [1] or software that delivers a business application through a communication protocol. [2] For a typical web application, the application server sits behind the web servers.
[2] [11] A growing body of research in service availability is accelerating the development of OpenSAF features supporting mission-critical cloud and microservices deployments, and service orchestration. [12] [13] OpenSAF 1.0 was released January 22, 2008. It comprised the NetPlane Core Service (NCS) codebase contributed by Motorola ECC. [14]
Micronaut is an open source JVM-based framework for building lightweight microservices. [1] [2] It is designed to avoid reflection, thus reducing memory consumption and improving start times. [3] [4] Features which would typically be implemented at run-time are instead pre-computed at compile time. [5] [6]
