    Top 49 Must Have DevOps tools for 2021

    Creating software products without DevOps and DevOps tools is nearly impossible today. Unless you are a huge fan of buggy code and chaotic version deployments.

    Development Operations professionals, combine IT, QA, infrastructure, and even some development tasks in their work. Devops are increasingly important members of any R&D department aiming to efficiently produce and deploy software products. 

    DevOps are tasked with speeding up release times and for improving the quality of code as well as the effectiveness of developers, ops, security, and testers. But what is it that makes DevOps so important, and what is it they do, exactly?

    What is DevOps?

    DevOps, the term and the approach, are the melding of ‘development’ and ‘operations.’ It involves the integration of processes and methodologies, the acquisition and deployment of new tools, and a cultural nexus of a sort.

    This “nexus” role of DevOps professionals is to encourage and facilitate collaboration between the stakeholders along the software development lifecycle. It is considered a critical aspect of the success and cost-effectiveness of a software development journey. 

    Among the practices common to a DevOps organization are collaborative development, and continuous testing, release, deployment, monitoring, feedback, and optimization.

    Adopting DevOps as part of the product development cycle is something more organizations can benefit from. Examples include:

    • Reduced time to market by 50%
    • Reduced risk through the incorporation of security into the software lifecycle
    • Software that is more stable and secure with reduced failure rates of new releases
    • Increased deployment frequency
    • Accelerated mean time to recovery in the event of crashes 
    • Reduced lead time between fixes

    So it’s no surprise to see that in one recent survey, the impact of DevOps is one of significance: 

    • It is the second most practiced development methodology (after Agile/Scrum)
    • 59% of respondents can now deploy even multiple times a day
    • 66% report a greater ability to innovate

    DevOps is about people, processes and technology. It is often referred to as a movement and a culture and as such, requires organizations to  have in their arsenal the tools that enable all these benefits.

    In this post, we will present the top 49 DevOps tools to make your software development life cycle more efficient in 2021.

    Top 49 DevOps tools for 2021

    Below we provide a comprehensive list of tools covering the following categories:
