Automation: CI/CD Pipeline
Automation in the cloudnative context means first and foremost: Being able to describe the cloud infrastructure that is required via code. Microservices and Containers enable applications to be lean and dynamic, but they also require the right cloud environment to run in. A cloud developer wants to quickly deploy updates or app features. That’s where Infrastructure as Code (IaC) comes into play. With IaC, you can automate platform provisioning and application deployment in a consistent and repeatable manner. You avoid manual configurations and foster consistency by using code to create the desired state of the environment. This is especially useful for DevOps teams as they can quickly deliver applications.
DevOps is a term that spans across the entire software development life cycle. Starting with the specification of an application all the way to delivering and operating it – DevOps contains patterns and practices to enable faster and more reliable releases.
Another challenge of cloud native solutions and a rapidly changing environment is that deployments happen very frequently. In the past, converting software to production required vast documentation and many manual steps that lead to errors. Continuous Integration (CI) and Continuous Deployment (CD) ease this process massively.
CI allows it to consistently apply changes to software by building and running automated tests against the source code of a project. That way, it catches mistakes early. CD is used when freshly built packages are deployed to an environment. Hereby, scripts replace the traditional checklists and allow to execute the same tasks faster and more accurately. That way, it catches issues in the deployment process early.
By applying CI/CD, companies can conduct code changes more frequently and thus provide on-demand updates instead of quarterly or even yearly releases. It not only caters to the agile demands of every cloud native software, but also leads to better collaboration and software quality.
