 ## Infrastructure
+
 ### SDN Laboratory
+
 Software Defined Networking (SDN) is an architecture that uses open protocols to provide centralized, programmatic control and network device monitoring. In SDN laboratory, applications deployment is performed on app server and related testing on test server.

 * Automated updating through script developed that could update the load.json file for the respective application. This script needs to be run once while deployment. Refer this for further details [FakeToOriginalIPConverter](../../server/FakeToOriginalIPConverter/README.md)

 ## Tools
+
 To achieve automated testing and deployment process, requires a SDN pipeline dockerize environment setup using below mentioned tools,   which give how NodeJS applications deploy as a docker container through Jenkins and running automated test suites for every commit from GitHub develop branch.
+
 ### Jenkins
+
 Jenkins is an open source continuous integration/continuous deployment (CI/CD) automation software tool written in Java programming language. It helps to automate the software activities like building, testing, deploying which makes easier to developers to deliver the Software modules. It is the leading tool for CI.

 ### Docker

 Docker is an open source platform that enables developers to build, deploy, run, update and manage containers of applications. It is used to automate the deployment of software in lightweight containers which can run on any OS environment. These containers helps applications to work efficiently in different environments.

 ### HAScripts

 HighAvailability is an ability to monitor/operate the services continuously with minimal of zero failures. Current architecture have multiple instances of applications running and if one of them crashes, still have the other instances working and available. HA will make sure that all instances are up and running, If required will resume the crashed instances also.

 ## Acceptance Testing
+
 Acceptance testing is a quality assurance (QA) process and this technique performed to determine whether software system has met user/business requirement specifications. It evaluates quality of software. Acceptance Testing run on testbed environment and if everything ok, then approve and  build go for deployment in production environment.

 ## Integration Testing
+
 Integration Testing is finalized testing of software product. Normally software products are divided into different modules and here SDN applications are also developed as individual services. This testing verifies that  software modules are integrated logically and tested as a group. The purpose of this level of testing is to expose defects in the interaction level and checks the proper service/data communications happen among modules/Applications.
