What is DevOps ?
What is DevOps ?
- The DevOps may be a combination of two words, one is software Development, and second is Operations. This allows one team to handle the whole application lifecycle, from development to testing, deployment, and operations. DevOps helps you to scale back the disconnection between software developers, quality assurance (QA) engineers, and system administrators.
- DevOps promotes collaboration between Development and Operations team to deploy code to production faster in an automatic & repeatable way.
What is devops ?
- DevOps helps to extend organization speed to deliver applications and services. It also allows organizations to serve their customers better and compete more strongly within the market.
- DevOps also can be defined as a sequence of development and IT operations with better communication and collaboration.
- DevOps has become one of the foremost valuable business disciplines for enterprises or organizations. With the help of DevOps, quality, and speed of the application delivery has improved to an excellent extent.
- DevOps is nothing but a practice or methodology of creating devops-architecture "Developers" and "Operations" folks work together. DevOps represents a change within the IT culture with an entire target rapid IT service delivery through the adoption of agile practices within the context of a system-oriented approach.
- DevOps is all about the integration of the operations and development process. Organizations that have adopted DevOps noticed a 22% improvement in software quality and a 17% improvement in application deployment frequency and achieve a 22% hike in customer satisfaction. 19% of revenue hikes as a results of the successful DevOps implementation. DevOps Free Course is recommended for getting expertise in DevOps methodologies.
History of DevOps
- In 2009, the primary conference named DevOpsdays was held in Ghent Belgium. Belgian consultant and Patrick Debois founded the conference.
- In 2012, the state of DevOps report was launched and conceived by Alanna Brown at Puppet.
- In 2014, the annual State of DevOps report was published by Nicole Forsgren, Jez Humble, Gene Kim, and others. They found DevOps adoption was accelerating in 2014.
- In 2015, Nicole Forsgren, Gene Kim, and Jez Humble founded DORA (DevOps Research and Assignment).
- In 2017, Nicole Forsgren, Gene Kim, and Jez Humble published "Accelerate: Building and Scaling High Performing Technology Organizations".

Why DevOps ?
- The operation and development team worked in complete isolation.
- By enabling organizations to create stronger bonds between Dev, Ops and other stakeholders in the company, DevOps promotes shorter, more controllable iterations through the adoption of best practices, automation and new tools.
- DevOps is not a technology, but it covers everything from the organisation to culture, processes and tooling.
- Initial steps usually include continuous integration and continuous development, real-time monitoring and collaboration platforms.
- DevOps adoption is growing rapidly.
- IDC forecast the worldwide DevOps software market to reach $6.6 billion in 2022, up from $2.9 billion in 2017.
- The forces driving DevOps adoption include enterprise investments in software-driven innovation, adoption of microservices-based architectures and associated development methodologies, and increased investment by CTOs and CEOs in collaborative and automated application development and operational processes, says IDC analyst Stephen Elliot.
- After the design-build, the testing and deployment are performed respectively. That's why they consumed longer than actual build cycles.
- Without the use of DevOps, the team members are spending an large amount of your time on designing, testing, and deploying rather than building the project.
- Manual code deployment results in human errors in production.
DevOps Architecture Features
Here are some key features of DevOps architecture, such as:
Devops architecture features
Integration
- Applications need to be integrated with other components within the environment.
- Continuous integration and testing enable continuous development. The frequency within the releases and micro-services results in significant operational challenges.
- To overcome such problems, continuous integration and delivery are implemented to deliver during a quicker, safer, and reliable manner.
Automation
- Automation most effectively reduces the time consumption specifically during the testing and deployment phase.
- For contiguous delivery, each code is defined through automated tests, cloud-based services, and builds. This promotes production using automated deploys.
Collaboration
- The teams share their responsibilities and work closely in sync, which in turn makes the deployment to production faster.
- The Development and Operations team collaborates together as DevOps team which improves the cultural model because the teams become simpler with their productivity which strengthens accountability and ownership.
Configuration management
- It ensures the application to interact with only those resources that are concerned.
- The configuration files aren't created where the external configuration to the application is separated from the ASCII text file.
- The configuration file are often written during deployment, or they will be loaded at the run time, counting on the environment during which it's running.
DevOps Advantages and Disadvantages
Advantages
- It responds faster to the market changes to improve business growth.
- DevOps escalate business profit by decreasing software delivery time and transportation costs.
- It is an excellent approach for quick development and deployment of applications.
- It improves customer experience and satisfaction.
- DevOps simplifies collaboration and places all tools in the cloud for customers to access.
- DevOps means collective responsibility, which leads to better team engagement and productivity.
Disadvantages
- Expert's developers are less available.
- Developing with devops is so expensive.
- Adopting new DevOps technology into the industries is very hard to manage in short time.
