People in an organization may know about the DevOps department but might be confused about what it truly is and its role. Explaining DevOps, even in plain English, is tricky. Through this blog, we will cover every possible query on DevOps. <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

What is DevOps? <\/h2>\n<\/div>\n<\/div>\n\n\n\n
\n
\n

DevOps is a combination of two words, \u2018development\u2019 (Dev) and \u2018operations\u2019 (Ops), that unite people, processes, and technology for swift application planning, development, delivery, and (last but not least) operations.   <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

To explain further, DevOps lets siloed roles such as development, quality engineering, and IT operations coordinate and collaborate safely.   <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Organizations adopt DevOps culture, principles, practices, and tools to grow productivity and quality in the applications they develop and achieve extraordinary business goals quickly (which might seem impossible with traditional development processes). DevOps assists teams in providing value to consumers in the same manner as a customer by producing reliable and better products for years.   <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

The History of DevOps   <\/h2>\n<\/div>\n<\/div>\n\n\n\n
\n
\n

Before the conception of DevOps, most software was developed and updated using the classic waterfall methodology- considered a linear approach to large-scale development projects. Software development<\/a><\/strong> teams would spend months completing one single project, as developing a wide and new code base involved extensive changes.   <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Afterward, the quality assurance (QA), security, and operations team would initiate their process, adding several more months to the final project delivery. The situation was so critical that it took months and, in many cases, years between software releases- the final delivery needed to be delivered without any bugs.   <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

In short<\/em><\/strong><\/span>, the development process needed a smart, advanced, and better solution<\/strong><\/span>.<\/em>  <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

To fasten the development process, development teams adopted agile software development methodologies. The agile method, more iterative than linear, came in handy as it focused on making smaller and more frequent updates to the application code base.   <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

The prevailing principles of such methodologies are continuous integration (CI) and continuous delivery (CD). In CI\/CD, new code is continuously merged into the code base every one or two weeks (or whenever code is ready), and then it is automatically tested for the final outcome.   <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

As the agile development practices integrated more often, they exposed still-siloed IT operations giving an edge to acceptance, testing, management, and monitoring- as the next step in the software delivery lifecycle.  <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Slowly but steadily, DevOps outgrew agile and added new tools that extended CI\/CD automation steps to the rest of the existing software development lifecycle. And it gave a powerful push to a close collaboration between development and operations.  <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

So, When Did DevOps Became a ‘Thing’?  <\/h2>\n<\/div>\n<\/div>\n\n\n\n
\n
\n

In the wide acceptance of DevOps, one name, Patrick Debois, comes up more than once. And other significant characters such as John Allspaw (senior vice-president of technical operations), Paul Hammond (director of engineering), Gene Kim, and John Willis.   <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

In 2007, Patrick Debois started working on a large-scale data center to which he was assigned as in charge of testing. As for the information available, it has been mentioned that he experienced numerous challenges and frustrations during the development process as it took extended time and repetition.   <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

He suddenly realized the lack of unity between two crucial steps in the development process (this went on for a while).   <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Then later, in June of 2009, John Allspaw and Paul Hammond gave a lecture titled “10+ Deploys a Day: Dev and Ops Cooperation at Flickr”, which inspired Patrick Debois to strengthen his ideology.   <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

In October 2009, Patrick Debois called developers and industry experts to figure out what could be done. The event grabbed everyone’s attention who was interested in inventing a better and more advanced solution.   <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

The event sparked small businesses’ interest in trying the DevOps methodology. People were getting an clarity on what is DevOps and it wasn’t long before its potential was recognized.   <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Then finally, in March 2011, Cameron Haight of Gartner expressed his thoughts on the trajectory of DevOps in the coming few years. And businesses\/enterprises did not hesitate to give DevOps a fair trial.   <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

How does DevOps Work?  <\/h2>\n<\/div>\n<\/div>\n\n\n\n
\n
\n

To totally tap into DevOps, one must understand what is DevOps and how does it work. To be blunt, know that DevOps is not just about “tools”; in DevOps, how people process work also matters greatly. How people implement the process decides whether DevOps would be utilized entirely to its capacity or not.   <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

DevOps puts an end to the traditional silo structure between the engineering team developing an application (or services) and (any) department managing that service while running in production. Processes and Work are aligned to the entire DevOps Lifecycle (of the products or services)- for final delivery and operation. <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Typically, the number of workflows can be divided into six parts; <\/h3>\n<\/div>\n<\/div>\n\n\n\n
\"\"<\/figure>\n\n\n\n
\n
\n

Ideation  <\/strong><\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

In this stage, prime attention is shined upon new features and functionality that’ll also prioritize in the next release. Teams investigate end-user feedback, available case studies, and stakeholders’ input. The aim stands still to maximize the value of a product. <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Development   <\/strong><\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

After ideation comes the ‘programming’ step. In this stage, developers put on their caps to test, code, and build new and efficient features. Different practices are pondered and worked upon, such as test-driven development (TDD), peer codes, and pair programming (and others).   <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

CI\/CD  <\/strong><\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Now comes the challenging yet exciting part. In this workflow, new code gets integrated into the existing code. After complete integration, the code is tested and packaged into an executable state for deployment.  <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Continuous Deployment  <\/strong><\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Tests are executed at this stage to test for quality and security. If any errors are found, developers solve issues before end-users see them.   <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Operations <\/strong><\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Once features are integrated into operations, monitoring of features and behavior is initiated. Operations ensure that features are running correctly and cause no obstacles in service. A significant work process of operations is to determine if there are any interruptions or alerts and if there are any- then it’s fixed as soon as possible. <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Continuous Feedback   <\/strong><\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Feedback from end users and consumers on different aspects, such as features, functions, and performance, is gathered and analyzed at this stage. This can also include backlog items, criticism, or pain points from the operations activities. All this positive feedback empowers developers to be extra attentive and avoid any mistakes. <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

DevOps Core Principles  <\/h2>\n<\/div>\n<\/div>\n\n\n\n
\n
\n

There are a few core principles of DevOps. They are divided in the manner below. For DevOps engineers knowing these principles is a must.   <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Extensive Thought Process  <\/strong><\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

To analyze the performance of an entire system instead of focusing on specific teams’ outcomes. This kind of thought process or systems thinking ensures that every team and employee feels the same way and is responsible for delivering good quality products. We tell you this is a genius way of processing workflow as it also discourages teams from passing any defective or not working downstream.   <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Implementing Culture: What is DevOps Culture?  <\/strong><\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

In the DevOps work process, immense significance is attached to a positive work environment utilizing best practices. A thriving DevOps culture is tightly tied to improved team collaboration, experimentation, and continuous learning. This way, teams get excited and interested in their work and are rewarded for taking risks to improve the system\/product, enabling team members to learn within their team.    <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Automation   <\/strong><\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Emphasizing automating as much as possible is a super-specialty of DevOps. In DevOps, it is believed that automating can reduce total time spent on project development and repetitive tasks, eventually increasing deployment speed. The DevOps team delivers constant feedback to eliminate any chance of interruptions at the final stage of delivery.   <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

DevOps Best Practices  <\/h2>\n<\/div>\n<\/div>\n\n\n\n
\n
\n

Continuous Integration (CI)  <\/strong><\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

It means getting frequent feedback from stakeholders and fixing the issue into a product instantly and continually. This practice creates a culture in which continuous integration happens with full support.   <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Continuous Delivery (CD)  <\/strong><\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

With continuous delivery, changes to a product, such as your code, are integrated automatically so that the product always stays in a deployable state. This practice certainly increases the product delivery state, as code is often deployed in short time frames.   <\/p>\n<\/div>\n<\/div>\n\n\n\n
