What is DevOps? 

What is DevOps?

DevOps is an amalgamation of software development and IT operations. It allows organisations to improve and deliver their products faster than conventional software development models. This enables organisations to effectively & efficiently service their customers and command a strong reputation in the market. For Example: 

  1. Amazon Web Services (AWS) is a leader in using DevOps methods. They use DevOps to regularly introduce new features and improvements, which means customers get new services faster. AWS manages its extensive tech systems using ‘infrastructure as code,’ and they use computers to automate testing, putting things online, and keeping an eye on everything. This helps them respond to customer needs swiftly.
  2. Google uses DevOps techniques to make sure their services like Google Search and Google Cloud Platform work well. They also do something called site reliability engineering (SRE), which is like a mix of DevOps and software engineering, to make sure their services are reliable and work smoothly.
  3. The origin of DevOps 

    DevOps originated in 2008 when developers Andrew Clay and Patrick Debois initiated its inception. Seeking solutions to prevalent challenges within agile development, which encompassed diminished collaboration due to project expansion and the adverse effects of incremental delivery on long-term results, the duo put forth an innovative concept: a unified DevOps pipeline facilitating continuous development and delivery. Following the DevOps Days event 2009, the term gained momentum and swiftly became a prominent industry buzzword. 

    Over a decade, the DevOps framework has transcended buzz and proven its substance. Its most substantial advantage lies in heightened efficiency and effecting a cultural transformation that fundamentally alters how companies approach every facet of the software development lifecycle. 

    In recent times, DevOps has undergone a more profound evolution, largely due to the contributions of industry luminaries like Gene Kim. As a keynote speaker at Perform 2021 and the author behind works such as “The DevOps Handbook” and “The Phoenix Project,” Gene Kim has played a pivotal role in advancing the understanding and implementation of DevOps principles. 

    How does DevOps function? 

    A DevOps model consists of a development team merged with the operations team during the entire application lifecycle (i.e., development, testing, deployment, and operations) instead of the method where both these teams worked independently in earlier models. Other teams, such as security, are also integrated with this team. In that case, it becomes known as DevSecOps. DevSecOps is like adding a security superhero to the team of people who build and manage computer programs.

    The goal is to make sure that security is thought about and taken care of right from the very start when the program is just an idea, all the way to when it’s up and running, and even after that. The overall function of a DevOps team is to automate processes that were manual earlier by using specific DevOps tools that help evolve applications rapidly and reliably. The DevOps tools enable team members to handle tasks independently without taking help from other teams. 

    What are DevOps practices? 

    DevOps practices are an organisation’s innovation objectives by automating and streamlining the software development and infrastructure management processes with the help of appropriate DevOps tools. 

    The following are DevOps practices available in the industry: 

    1. Continuous Development

      This practice involves the coding and development phases of the DevOps lifecycle. This also facilitates the version-control feature.

    2. Continuous Testing

      This practice involves the automated, pre-scheduled, and continued tests that should be executed against the application code. This includes continuously testing application code (update or fresh code) against pre-programmed tests.

    3. Continuous Integration

      This practice involves the continuous feedback mechanism between testing and development to make code ready for production as early as possible. It encompasses the configuration management, test, and development tools to mark the progress of the production-ready code.

    4. Continuous Delivery

      This practice involves delivering code changes to the staging environment and post-testing before going live in the production environment.

    5. Continuous Deployment

      This practice involves the delivery of code changes to the production environment. It uses container technologies such as Docker or Kubernetes to make production changes available rapidly.

    6. Monitoring and Logging

      This practice involves continuously monitoring application code in production and the infrastructure that supports it. It is necessary to monitor the environment 24/7 to continuously report issues or bugs to the development team to improve code quality.

    7. Infrastructure as Code

      This practice involves the automation of cloud infrastructure provisioning with the help of integrated tools. The infrastructure can be set up with the help of API-driven mechanisms to enable the developer to interact with it.

    1. Continuous Integration/Continuous Deployment (CI/CD)

      1. Jenkins

        Jenkins is a widely used open-source automation server that helps automate building, testing, and deploying code.

    2. Containerization and Orchestration

      1. Docker

        Docker is a platform for developing, shipping, and running applications in containers.

      2. Kubernetes

        Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications.

    3. Infrastructure as Code (IAC)

      1. Terraform

        Terraform is an open-source IAC tool for building, changing, and versioning infrastructure efficiently.

      2. AWS CloudFormation

        CloudFormation is AWS’s native IAC service for defining and provisioning AWS infrastructure.

    4. Security

      1. HashiCorp Vault

        Vault is a tool for secrets management and data protection.

    5. What is Observability in DevOps?

      DevOps integrates development and operations within a cohesive structure that dismantles barriers and encourages collaboration throughout the entire software lifecycle. In this setting, Site Reliability Engineers (SREs) can enforce operational practices that guarantee the accessibility, speed, effectiveness, and robustness of software systems. Concurrently, Continuous Integration/Continuous Deployment (CI/CD) methodologies can offer closely aligned and automated development, testing, delivery, and deployment approaches. 

      Benefits of DevOps

      1. Enhancing Efficiency through Automation

        According to the late DevOps expert Robert Stroud, the essence of DevOps lies in propelling business transformation, encompassing changes in people, processes, and culture—the most impactful approaches for achieving DevOps transformation centre on structural enhancements that foster a sense of community. A successful DevOps venture necessitates a shift in culture or mindset, fostering increased collaboration among diverse teams such as product, engineering, security, IT, and operations. Automation is also integral to attaining business objectives more effectively.

      2. Boosting Entire Business Optimization

        Renowned system architect Patrick Debois, credited as the creator of the DevOps movement, highlights DevOps’ most significant advantage as providing comprehensive insight. It compels organisations to optimise the system, enhancing the overall business rather than just isolated IT components. In simpler terms, it encourages adaptability and data-driven approaches that align with customer and business requirements.

      3. Enhancing Speed and Stability in Software Development and Deployment

        An extensive analysis over several years, as documented in the annual Accelerate State of DevOps Report, indicates that top-performing DevOps entities excel in software development, deployment speed, and stability. They also meet the critical operational objective of ensuring the availability of their products or services to end users. However, given the somewhat vague nature of DevOps, how can an organisation ascertain the effectiveness of its DevOps endeavour? The 2019 Accelerate report identifies five performance metrics—lead time (the duration from code commitment to successful production deployment), deployment frequency, change failure rate, time to restore, and availability—that offer a high-level overview of software delivery and performance. These metrics can also forecast the likelihood of DevOps success.

      DevOps principles have expanded beyond software development and are now applied in various industries like healthcare, finance, and manufacturing. In healthcare, DevOps speeds up software delivery for critical applications, ensuring timely access to patient data. It also aids in security and compliance, maintaining data safety while innovating in patient care. During the pandemic, DevOps played a role in quickly scaling and maintaining telehealth platforms. In finance, DevOps manages risk, supports high-frequency trading with low-latency systems, and enhances customer experiences through rapid feature development. In manufacturing, it automates and optimizes production, resolving quality and efficiency issues through continuous monitoring and analysis. 

      Continuous learning and getting better are key principles in DevOps, and they’re super important. They help teams keep up with changes in technology, find and fix problems early, make systems tougher, and come up with new and cool ideas. It’s all about staying sharp, improving quality, and sparking innovation.

      A key practice that helps teams learn and innovate in DevOps is ‘Blameless Post-Mortems.’ Here’s how they work and why they matter: They’re a structured way to look at what went wrong without pointing fingers. The main goal is to figure out what happened, why it happened, and how to stop it from happening again. They encourage open and honest talk among team members, creating a safe space where people aren’t scared to admit mistakes or report problems. They write down important findings and what needs to change, and they keep track of what’s done to make things better. Blameless post-mortems build a culture where the whole team takes responsibility for the system’s health and performance. 

      Challenges of DevOps  

      Numerous hurdles are present within a DevOps undertaking. Reimagining an organisation’s structure to enhance operational efficiency is a complex endeavour. However, companies often need to pay more attention to the extensive effort required for a successful DevOps transformation. A recent Gartner study indicates that up to 75% of DevOps initiatives until 2020 fell short of achieving their objectives due to organisational learning and change challenges. 

      According to George Spafford, a senior analyst at Gartner, “Organizational learning and change are pivotal for fostering the growth of DevOps. Remarkably, the primary challenges tend to be human-related rather than technological.” 

      1. Selecting the appropriate metrics

        As Forrester advised, enterprises transitioning to DevOps methodologies must employ metrics to gauge progress, validate accomplishments, and uncover areas needing enhancement. For instance, an increase in deployment speed without a corresponding enhancement in quality does not signify success. Effective DevOps implementation requires metrics that drive informed decisions regarding automation. However, many organisations need help with DevOps metrics.

      2. Complexity

        DevOps efforts can become entangled in intricacies. IT leaders might need help conveying their work’s business value to key executives. Regarding governance, questions arise about whether centralisation and standardisation lead to improved outcomes or merely introduce additional layers of stifling bureaucracy. Additionally, there’s the challenge of organisational change: Can teams overcome resistance to change and inertia? Can they unlearn practices entrenched over the years, share their knowledge, learn from peers, and effectively integrate and orchestrate the right tools?

      DevOps, as a field, continues to evolve rapidly, driven by technological advancements and changing business needs. Here are some current trends in DevOps and insights into its future directions: 

      1. GitOps

        GitOps, a hot trend in DevOps, involves using Git repositories as the main source for managing infrastructure and application settings, with changes made through pull requests to encourage teamwork and clarity. Looking ahead, GitOps is poised to become even more connected with CI/CD pipelines and cloud-native tools, likely becoming a central method for handling infrastructure and applications across diverse cloud setups and hybrid environments.

      2. AIOps (Artificial Intelligence for IT Operations)

        AIOps, a current trend, uses AI and machine learning to automate and improve tasks in IT operations, like monitoring, spotting anomalies, and handling incidents. In the future, as AI and ML get better, AIOps will become even more crucial in DevOps. It’ll heavily rely on predictive analytics and automation to foresee and address problems, making systems more dependable and reducing downtime.

      3. DevSecOps Evolution

        A trending practice known as DevSecOps is all about blending security into DevOps, making it a crucial part of the process. It involves automating security checks, raising security awareness, and moving security concerns earlier in development. Looking ahead, DevSecOps will grow even more important as cyber threats change. It will evolve to include advanced threat detection and response and will get closely linked with compliance and risk management.


      DevOps is a dynamic and ever-evolving field, constantly shaped by technological advancements and changing industry needs. As organizations across various sectors embrace DevOps principles and practices, staying updated with the latest developments and best practices is of paramount importance.

      To thrive in the DevOps landscape, ongoing education, certification, and participation in communities of practice are valuable assets. By staying informed and engaged, individuals and teams can harness the full potential of DevOps, driving innovation, resilience, and continuous improvement across the organization. In a world where change is constant, being at the forefront of DevOps knowledge is not just an advantage—it’s a necessity.
