Continuous delivery: Streamline your software releases
Continuous delivery (CD) is a software engineering approach where teams produce software in short cycles, ensuring that the software can be reliably released at any time. It automates the steps required to deploy a build, allowing for more frequent and rapid releases. This reduces the risk associated with large, infrequent releases and enables faster feedback loops, leading to quicker improvements and greater customer satisfaction.
What to look for in continuous delivery freelancers
When hiring a continuous delivery freelancer, look for demonstrable experience in:
- Building and maintaining CI/CD pipelines
- Automating deployments to various platforms (e.g., AWS, Azure, Google Cloud)
- Configuration management tools (e.g., Ansible, Puppet, Chef)
- Containerisation technologies (e.g., Docker, Kubernetes)
- Scripting languages (e.g., Bash, Python, Groovy)
- Version control systems (e.g., Git)
- Experience with various testing methodologies (unit, integration, end-to-end)
Main expertise areas
In addition to specific programming languages and frameworks relevant to your project, clients should inquire about a freelancer's expertise in areas like:
- Cloud platforms: AWS, Azure, Google Cloud, etc.
- CI/CD tools: Jenkins, GitLab CI, CircleCI, Azure DevOps, etc.
