Decoding The Difference Between Agile & DevOps

Pavithra S 2 years ago

Thanks to the emergence of IT industries! Software development, today, is exploding in this technology-driven world with new software programs to meet different business needs. There is a system development methodology to support the design and the development of software to meet specified needs, maintenance, and production. In that line, Agile and DevOps are two major software development methodologies that most of today’s business teams use to bring software faster and more efficiently in the market.

Agile and DevOps are two standard methodologies that have a similar aim, which is, getting the end-product out swiftly and effectively as possible. Though Agile and DevOps have a lot in common, there are notable differences between them. Before elucidating the differences between these methodologies, let’s get to know what exactly do Agile and DevOps mean and how they function in a team-based environment.

What is Agile?

It is a popular software development methodology introduced in 2001 along with the agile manifesto. It engages twelve principles and four values to build an agile software development culture. In brief, Agile is an iterative approach that encourages organization, collaboration, and feedback to complete projects quicker and more efficiently. It focuses more on aligning development concerning customer needs and current trends. It is mainly used on the project management side of software development to ensure all the individuals in a team can accomplish tasks quickly without compromising quality. The Agile software methodology is executed with smaller teams and segments with constant testing and changes made as required based on the recent customer feedback.

The 12 principles and 4 core values in the Agile Manifesto include

  • Customer satisfaction is the top priority
  • Accept changing needs, even late in the developments
  • Provide working software frequently
  • Business and development must go hand in hand
  • Build projects around interested people
  • Face-to-face communication for effective conveying of information
  • Working software to be the primary measure of success
  • Promote software development
  • Pay continuous attention to good design and technical excellence
  • Simplicity is important
  • The best designs, architectures, and requirements emerge from self-organizing teams
  • Reflect on work regularly, tune and adjust behavior

Core Values

  • Customer collaboration over contract negotiation
  • Individuals and interactions over tools and processes
  • Working software over comprehensive documentation
  • Responding to change over following a plan

DevOps

This software development methodology aims to bring Informative Technology (IT) and software development teams to work together throughout the software development lifecycle. It is a concept that promotes collaboration between teams that previously worked separately from the initial design phase to product release. Its main objective is to improve the speed of product development and deployment. DevOps methodology connects software development (Dev) with operations (Ops). Its main intent is to enable efficient communication between teams that help them build, test, and release software faster with greater efficiency, and speed. DevOps promotes continuous integration, deployment, automated testing, and transparency in code repositories.

Agile Vs DevOps: The Key Differences

Although both Agile and DevOps software development methodologies encourage collaboration between teams to work together and improve speed and efficiency, there have several differences when it comes to the method by which their goals are attained. Read through to know some critical differences between Agile and DevOps.

Process

The major difference in the Agile Vs DevOps is the methodology of how specific tasks are performed. With Agile, communication is constant between customers and teams with necessary changes being made regularly throughout the production process to guarantee quality. About DevOps, the main focus is on frequent testing and delivery while the communication is maintained primarily between IT Operation and Developer teams. While Agile is ideally suited for a complex process, DevOps is best for end-to-end processes.

Team Structure

The structure of teams is another critical difference between DevOps and Agile. Larger teams tend to employ DevOps with the expertise divided among team members within development and operations. This implies each team member will be given a specific task throughout each stage of the process to complete. On the other hand, the Agile approach doesn’t specifically assign a set of duties to team members. Instead, it encourages all members of the team to share their responsibilities equally and that’s why they are able to handle any part of a project at any given time. Agile is efficient for smaller teams to complete their work faster.

Usage of Tools

DevOps and Agile use different tools based on the project. The common project management tools with Agile include Jira project management software, Kanboard, and Bugzilla server software. Conversely, tools like Puppet automation software, AWS cloud computing services, OpenStack software, Chef Infrastructure, and TeamCity Servers are used with DevOps.

Focus & Feedback

When it comes to focus and feedback, DevOps tend to concentrate more on operational and business readiness getting most feedback from the internal team members. The Agile approach differs by getting feedback directly from consumers. Agile teams focus on frequently used sprints, with each one lasting less than a month. The sprints idea denotes the achievable tasks are completed in increments, with one sprint commencing right back after the previous one is accomplished. DevOps has specific deadlines and benchmarks to meet and achieve, some of which can occur every day.

Can Agile & DevOps Be Combined?

The good news is that a mix of both methodologies can be used in a business to ensure speed and efficiency. Both DevOps and Agile play a major role in the software development and deployment process and one methodology can be used to facilitate the other.
