DevOps adoption keeps booming despite economic uncertainty.

86% of businesses admit the importance of faster development and releases, based on a study by Harvard Business Review on DevOps implementation. Yet, only 10% are very successful with faster deployments.

The tech stack is one of the biggest bottlenecks. DevOps lacks standard approaches, and the team must know which tools and technologies are the best available and how to use them with maximum efficiency. 

Let’s look at the best open-source DevOps tools for speeding up innovation and software delivery. Plus, the key considerations.

1 What are DevOps Tools?

DevOps tools encompass a wide variety of platforms, utility programs, and tools needed to collaborate across the entire software lifecycle: 

  • continuous integration
  • continuous delivery
  • automation at scale
  • collaboration

Unless you have a simple app, you will need a toolchain: DevOps engineers use 10.3 tools on average. This steepens the DevOps learning curve. 

Soft skills are equally crucial. Implementing proprietary and open-source DevOps tools is possible with a cultural shift in the project organization. 

For instance, DevOps for startups goes beyond Agile methodology to connect app development and maintenance within one seamless process.

2 How to Choose the Right Open-Source Tools for DevOps in 2024?

Key considerations affecting the choice of to-be-integrated instruments include: 

  • Popularity

Risks of vendor dependence are lower when using popular tools with large communities and backed up by large teams. You get assistance faster when encountering a problem. Updates are regular.

  • Environment

Choose effective instruments for your infrastructure type: a private, public, hybrid cloud, or bare metal. Some technologies are platform-specific and can block project transfer to a competing platform.

  • Customization

Think of an all-in-one vs. open DevOps toolchain. The former provides a complete set, which is best for starting. The latter is a custom-built mix of various tools, granting the best flexibility and adaptability.

  • Integrations

If you have already applied DevOps technologies to your project, consider the open-source DevOps tools you can easily integrate with the existing stack. Avoid heterogeneous ecosystems and, thus, unnecessary complexity.

  • Costs

Although many tools are free, convenience comes at a price. Tools can tie you to a specific cloud provider. Or the features you need can be hidden behind a subscription. Carefully weigh what you get.

An important point here. All instruments often have subtle nuances in their use. Ensure that the composed DevOps toolchain covers all steps of your DevOps transformation map

  • Planning

Break the scope of work into small chunks, considering the challenges of both development and maintenance teams.

  • Building

Manage the same environments across all stages. Eliminate manual provisioning.

  • Integration

Automatically check produced source code, detecting problems and improving stability. 

  • Deployment

Reduce time to production. Ensure frequent code deployments. 

  • Operation

Optimize resource consumption. Scale smart. Monitor system health. 

  • Feedback

Turn collected feedback into actionable insights that serve scope planning.
