If you have been searching for “How to Learn DevOps online?”, this is a complete DevOps tutorial, where you will learn:
What is DevOps & why is it used?
DevOps is a combination of two words - Dev = Development, Ops = Operations, defining culture, or infrastructure where the development & operations team collaborate & communicate to deploy codes to result in faster production in an automated manner.
DevOps speeds up the organization’s ability to deploy the technology products faster and gives scope to serve the customers in a better & competitive way.
Benefits of DevOps to Organizations
DevOps is a concept of the contemporary world that promotes continuous integration and continuous development application and software at high speed and high velocity. Various beginners to professionals are fascinated by its alignment with any SDLC and various cloud platforms, let’s identify what are the other reasons that are making this technology a pioneer for enterprises and individuals.
Focuses on continuous improvements - Since DevOps ensures to align the business with IT, the bridge between delivery cycle and feedback gets shrunken and it gets easy to improve the processes for the internal and external customers over different platforms.
Reduces the failures - DevOps is implemented on top of the agile model, making it easy to promote collaboration, modular programming or so - which makes it easy to identify faults and errors in each task. DevOps is implemented in conjunction with fault detection techniques, which minimizes the failure rates with ease.
Gives extensive scope of innovation - Since the DevOps culture and processes are practiced with constant cooperation and continuous delivery, the team gets the constant scope to work on creative and innovative outcomes.
Tasks are not siloed - In IT, A silo software development describes a situation where any particular management system works in the discretion or isolation from other systems. Silos lead to disparate systems in the same business environments, to overcome the shortcomings of the silo, DevOps is the perfect addition that ensures in an organization, there is no conventional departmentation and allows the systems, processes, teams to cooperate and collaborate - to result in continuous and innovative outcomes.
Performance-centric environment - DevOps embodies organizations with a combination of power-based and performance-based features. The technology enforces a way out for the organization’s teams & processes to collaborate, in a way the quality of the product is uplifted, while the workforce is taught to become creative and innovative with regular integration and deployment phases.
Why do Organizations use DevOps?
DevOps integrates the development & operations team to engineer a unified & end-user centric product.
DevOps sync the “development” and “operations” team delivery deadlines.
DevOps decreases the costs done individually on designing, deploying, testing.
Automate the coding deployment with various tools to avoid errors in production.
DevOps helps to create an omission-free product for end-customers disposal.
DevOps reduces defects across the SDLC, breaks the large & complex codebase into simpler & manageable chunks, and can be fairly used for eCommerce to websites hosted on cloud platforms.
DevOps acknowledges a lower failure rate of new releases, reduces products time-to-market by 50%, and incorporates infrastructure issues to provide quality application development.
DevOps Lifecycle
DevOps brings all the development, IT professionals, operations teams with developers, system admins, QA Testers under one roof and constitutes a unified DevOps lifecycle as follows:
Phases
Explanation
Development
The entire development process is divided into smaller chunks to speed up the software development & delivery process.
Testing
QA teams leverage automated testing tools like Selenium to identify performance failure issues & bugs in the app prepared.
Integration
New functionality & features are added via integration with the prevalent codes, followed by rigorous testing.
Deployment
The developed product is deployed with careful interventions.
Monitoring
The operations team monitors the product for optimum performance & service uptime.
DevOps Workflows
Workflow reflects the visual & sequential implementation of the provided input.
It briefs about the actions that are performed and the outputs created for the operations process.
DevOps workflows give the ability to arrange & separate the jobs requested by users.
DevOps Principles
There are 6 DevOps principles that are important to follow while adopting DevOps.
To automate everything - To leverage automation throughout the SDLC to minimize errors & increase efficiency.
To have continuous improvement - To improve the products for reducing the wastage.
To work as a team - All the members of the development, designers & testing team must collaborate & communicate as one unified team.
To take end-to-end responsibility - To provide continuous performance support until the product’s lifetime, to ensure its maximized quality.
To take customer-centric actions - To constantly invest in products or services in the customer-centric way.
To keep on monitoring & testing everything - To identify & follow the robust testing & monitoring procedures.
DevOps Automation Tools
The following are the DevOps key tools that help with robust and automated deployment and monitoring of business applications.
Docker - A high-end DevOps tool that helps with architecting and running distributed applications on diverse systems. It is suitable for container management and helps with assembling the applications real quick.
Puppet - A widely-adopted DevOps tool that helps with automation testing, versioning, and continuous delivery. It helps to deliver & release the key technology changes quite fast & constantly.
Ansible - Ansible is used for end-to-end automation throughout the application lifecycle, the tool enhances productivity by taking care of complex deployments.
Jenkins - A popular DevOps tool that helps to monitor the execution of repeated jobs. Jenkins lets you integrate the changes fast and access the results quickly.
Nagios - The Nagios tool is suitable for monitoring the IT infrastructure, it can easily identify the errors and resurrect them with the help of log monitoring systems, server, and standard network.
Focused on diminishing the barriers between business management and the development teams.
It is all about diminishing the barriers between the development & operation teams.
Agile development is managed on sprints and has a small and fixed duration to complete the specific process.
It has consolidated deadlines rather than small & frequent ones.
Agile requires training of all team members with equal skills for emergencies.
DevOps divides the skills between the operations and development teams by maintaining consistent communication.
Have a focus on non-functional & functional readiness of the product.
Have a focus on business & operational readiness of the product.
Bridges the gap between development teams & customer requirements.
Bridges the gap between operations & development teams to ultimately build the customer-centric product.
Less critical to testing and implementation procedures.
Have elaborative processes to pursue deployment, testing & implementation stages.
Has less inclination to automated procedures.
Has more inclination to automated procedures.
