CI/CD Tools to Accelerate Software Delivery

CI/CD Tools

As a cornerstone of software development and DevOps, CI/CD tools considerably reduce the obstacles in tasks that would require more time and effort. For example, testing, integrating changes, and quickly releasing to customers. 

Combining the practice of Continuous Integration and Continuous Delivery integrates the automation needed for a fast and improved Software Development Life Cycle (SDLC). 

Let’s dive into the top CI/CD Tools, their features, their main characteristics, and their importance in DevOps. So, by the end of this blog, you will feel more confident in choosing the one that perfectly matches your project.

What is CI/CD?

CI/CD (and its tools) is essential for DevOps practices, with its foundations starting in the early 2000s when the concept of CI emerged as an extension of the agile development methodology. A few years later, CD also gained prominence as organizations realized the benefits of automating the deployment process. 

And finally, with the rise of Cloud Computing and DevOps methodology, automation in software delivery became a priority. In brief, these trends accelerated the adoption of CI/CD, transforming it into a fundamental practice. 

Continuous Integration is the practice where teams build and test small code modifications into a version control repository. To sum up, it is an ongoing process that uses automation tools for faster development. 

When CI ends, CD begins. So, Continuous Delivery or Deployment ensures those changes are automatically tested and deployed to the production environment. This way, teams are able to respond to the client’s needs and the market’s demands. 

Certainly, the key to a correct Continuous Integration and Continuous Delivery implementation lies in the CI/CD tools used in the DevOps workflow or pipeline. So let’s discuss more about it.

What are the benefits of CI/CD?

To begin with, let’s paint the picture. Imagine you’re building a product for a new client; it’s a complex platform, and your client requires frequent changes. So you need to focus on streamlined delivery while still reducing errors. Undeniably, as DevOps teams, CI/CD tools are essential to accomplish this.

Here are some of the top benefits of implementing CI/CD tools:

  • Quality and speed

Eliminating manual tasks reduce the time it takes for teams to identify issues and solve them. This means faster delivery of a valuable product with better quality. 

As a result, customer engagement and satisfaction will improve, teams will be more productive, and costs will reduce as well. 

  • Task automation

Indeed, automation is fundamental in software development and DevOps. Now, more than ever, it is necessary to implement strategies that streamline processes so that organizations can focus their resources on other priorities rather than using them on repetitive tasks. CI/CD tools enable a continuous DevOps process where building, testing, deploying, and updating code is automated.

  • Reduced Mean Time To Recover (MTTR KPI)

In brief, this metric measures how efficiently you can respond and solve issues that come up in the cycle in DevOps. With CI/CD tools, DevOps cycle time is reduced because your process will have fewer problems to fix, and your team will be able to attend to them faster.  

  • Observability

Certainly fundamental in DevOps, observability allows teams to quickly inspect the system to evaluate performance and identify any possible issues. CI/CD generates logs for comprehensive code monitoring in each step of the SDLC to study its behavior. As a result, it improves observability.

  • Cultural impact

Implementing a CI/CD pipeline not only offers organizations improvements for software development but also impacts the team’s productivity and satisfaction. Without a doubt, an automated, controlled, and observable process will allow them to stay up-to-date with their tasks and unplanned requirements that might arise.  CI/CD (and its list of tools) and overall DevOps trends and practices promote a culture of learning, responsibility, and collaboration, which ensures the team has all they need to drive more value to the organization.

CI/CD Workflow

A CI/CD pipeline or workflow includes a series of stages to deploy small code changes in a continuous and controlled process. It uses CI/CD tools for DevOps automation, accelerating deployment, and ensuring observability. Implementing the workflow has other general benefits like reduced costs and easier rollback to previous releases so QAs and stakeholders can access any version of the system. 

The number and order of phases of a CI/CD pipeline vary according to the project requirements and the organization’s resources. Here are the main and most common steps:

  • Code integration: In this stage, the code change is committed to a version control system.
  • Build and compilation: The code change triggers the pipeline. The code is compiled, dependencies are resolved, and artifacts are created.
  • Automated testing: This step includes automated unit and integration tests and could also involve performance and security testing to evaluate the code.
  • Deployment: Once the code is tested and ready, the next stage is deploying it to the correspondent environment. 

There are other steps for the workflow, like analyzing the code for potential issues or vulnerabilities, pushing the code to an artifact repository for easy access, and acceptance testing to validate the software behavior.

Also, the pipeline must include continuous monitoring to collect data for metrics and logs and continuous deployment implemented through automation tools.  

Overall, the workflow must be fast, reliable, and accurate so that developers can focus on building code while being confident that any change will be automatically tested and deployed. 

Get started with a CI/CD pipeline using Kubernetes, Docker, AWS CodePipeline, and the AWS Cloud Native tools: read the full blog here.

Choose the perfect CI/CD tools for a successful project.

There is no standard answer or tool fit for every business. However, there are several aspects to take into consideration when choosing the right CI/CD tools of the list, like how secure it is, if it’s open-source, the community support it offers, and, of course, the cost. 

Your CI/CD tools list must also have a high level of automation and provide adequate monitoring and reporting capabilities to improve your pipeline. 

Overall, the right tools will depend on the requirements of your project and your company. Here are some top questions you should ask as a guide to finding the correct list of CI/CD tools that are most compatible with your goals. 

How to Choose the Right CI/CD Tools?

  1. Does it integrate with other tools? Your chosen CI/CD tools of the list must integrate with your existing system to streamline processes and ensure collaboration between all implemented tools and services.

  2. Does it offer other tools besides CI? Besides integrating with other tools for its CI/CD capabilities, like Kubernetes or Terraform, some also offer other services and unique functionalities to streamline app development.

  3. How secure and compliant is it? Security must be a top priority when choosing CI/CD tools. What measures does it take to ensure security regarding access, vulnerability, credentials, and other collected data? Does it comply with the regulations your company is under? You must trust the tool you use because it will require specific access to complete tasks.

  4. What is the pricing model? The ideal costs will vary depending on your infrastructure and the conditions you have for your projects like features, users, level of usage, and extra costs (i.e the learning period of implementing a new tool might increment some expenses).

  5. Which hosting model do you use? Availability, scalability, and maintenance are directly impacted by the hosting model you use. With an on-premises model, you have more control but require dedicated resources. A cloud-based hosting involves a third-party provider’s infrastructure to handle infrastructure management so teams can focus on using the tool.

  6. Does it have good community support? The key is to find intuitive and user-friendly CI/CD tools with active community support. Overall, if you face any issues, have any questions, or are looking for additional resources, an available and extensive community will be right there for you.
