- 8. Let’s build a website for a company You can use DevOps tools and techniques to build your website Hey, I want to build a new website for my organization Organization
- 9. Let’s build a website for a company Let me hire some Developers, Testers and Operation guys who can develop, test and maintain the website After gathering all the requirements, the developers start building the code for the website and store each version of the code in a code repository (GitHub) GitHub Repository Developer 1 Developer 2
- 11. Version Control System File 1 File 2 File 3 File 1 File 2 File 3.3 Developers Developers Version 1 Repository snapshots snapshots Version 2 Git is one such popular Version Control Tool
- 12. Git Architecture Working Directory Local RepositoryStaging Area Remote Repository git add git commit git push git pull git checkout git merge Local Remote
- 13. Let’s build a website for a company Here, the developers will validate, compile, package and verify the codes Source Codes Build Now, the developers will build the code using various build tools
- 15. Let’s build a website for a company The testers will perform functional test, unit test, system test and user acceptance test Test Built Codes The testers will test the built code to makes sure there are no errors
- 17. Let’s build a website for a company Continuous Integration will make sure all the codes are continuously built, tested and deployed on the production server Integrate CI Server Code Repository The operations team will then integrate all the codes along with any newly built code
- 19. CI/CD using Jenkins Tester CI Server Repository Pass Fail Developers Errors Release and Deploy
- 20. CI/CD Build SystemCode Repository Test Framework • Unit Test • Web UI Test • Integration Test Robot Framework Continuous Integration Developers
- 21. CI/CD Continuous Delivery/Deployment CI Delivery after Integration Production Environment Google Cloud Platform Continuous Delivery Continuous Deployment
- 22. Let’s build a website for a company Configuration Management will make sure that all the systems are in operation and functioning properly and software is deployed on the systems Configure Production Operations team will then configure the systems and deploy the codes on to production environment
- 24. Configuration Management Configuration Management is the process of systematically managing and handling changes to a system in a way that it maintains integrity over time Configuration Management Database Configuration management Artifact Repository Source Code Repository Configuration Management in DevOps comprises of 3 components:
- 25. Puppet - Configuration Management Puppet is an open-source software configuration management tool for deploying, managing and configuring multiple servers Node Puppet Master 1 3 2 4 Report The node reports back to puppet master indicating the configuration is complete, which is visible in the puppet dashboard Catalog Puppet uses the facts to compile a catalog that specifies how the node should be configured Facts The node sends normalized data about itself to the Puppet Master SSL secure encryption on all data transport Report Collector (Puppet or 3rd party tool) Report Puppet’s open API can send data to 3rd party tools
- 26. Containerization Containerization is a process that allows software to run reliably when moved from one computing environment to another VM 1 VM 2 VM 3 VM 4 Host Machine VMs takes a lot of system resources and runs a full copy of an OS, as well as a virtual copy of all the hardware that the OS needs to run Virtual Machine Host Machine Docker Containers Solution
- 27. Docker Containers Docker containers are standard units of software that packages code and all its dependencies so that the application runs faster and is reliable from one computing environment to another Infrastructure Docker Host Operating System App A App B App C App D App FApp E Containerized Applications
- 28. Let’s build a website for a company Monitoring of the website will make sure it is up and running and end users are able to use the website without any problem Monitor Operations team Monitor website Operations team verify if the website is functioning correctly and the entire architecture is working properly
- 30. Monitoring Monitoring in DevOps is a process of detecting, examining and reporting if there are any faults or threats in the entire infrastructure Web ServerApplication Server Database Server You should ensure that all the services, applications and resources are running properly on these servers To make sure the complete infrastructure is working fine, we use tools like
- 31. Nagios Nagios tool allow you to monitor the servers and check if they are being sufficiently utilized or if there are any task failures that needs to be addressed Nagios monitoring tool helps you achieve these 3 goals: • Check the status of the servers and services • Verifies health of the infrastructure • Applications are working properly and web servers are reachable
- 32. Nagios Architecture Nagios Web Interface (GUI) Remote Resource or Service Remote Host Nagios Process/Scheduler Plugin Plugin Load resource or service Nagios executes plugin Plugin checks the status and sends results Plugin sends results to Nagios to process Nagios Server Notifies the admin about the status processed by the scheduler Plugin sends results to Nagios to process
