As we transition into an era of automation and data-driven decision-making, the role of CI/CD in software development becomes ever more crucial. The stakes are particularly high for companies like Ellenex operating in the Industrial IoT space. This blog post aims to provide a comprehensive guide for implementing CI/CD pipelines for a large fleet of microservices, specifically focusing on using Bitbucket Pipelines and deploying serverless applications to AWS.
Why CI/CD Matters in a Microservices World
In the Industrial IoT landscape, microservices allow for unparalleled scalability and flexibility. However, managing these services manually is no small feat. That's where Continuous Integration and Continuous Deployment (CI/CD) come in, automating the entire software development process from code commit to production deployment.
Tools We Use for Ellenex Microservice Platform
In the world of technology, there are no right or wrong answers. It is just a matter of preference and trade-offs. We chose the following tools for our platform. You can easily replace this with alternatives with similar features.
Source Control:
Ellenex uses Bitbucket for source control, which integrates seamlessly with Go's native Git support.
Build Tools:
Go comes with its own build system and package manager, making dependency management straightforward through Go modules.
CI / CD:
Bitbucket Pipelines are used for continuous integration and deployment, configured specifically to build and deploy Go applications.
Orchestration:
AWS Lambda supports Go, allowing the Ellenex microservice platform to deploy serverless applications effectively.
Designing the CI/CD Pipeline
Version Control Hooks
Utilize Bitbucket hooks for pre-commit and post-commit actions.
Automated Builds
Configure automated builds in Bitbucket Pipelines.
Automated Tests
Run unit and integration tests as part of the build process.
Deployment Strategies
Use AWS Lambda versions and aliases for blue-green or canary deployments.
Implementing the CI/CD Pipeline
To implement the CI/CD pipeline, you’ll need to configure a bitbucket-pipelines.yml file at the root of your repository. This YAML file will define all your build and deployment steps. Make sure it is configured to deploy your serverless applications to AWS Lambda.
Monitoring and Feedback
AWS CloudWatch can be utilized for real-time monitoring. Bitbucket also provides built-in features for build monitoring and logging, which can be integrated with your existing systems.
Challenges and Pitfalls
One of the main challenges is ensuring the security of the pipeline, particularly when integrating with cloud services. AWS provides several layers of security features that should be properly configured.
Conclusion
For industrial IoT companies like Ellenex, CI/CD isn’t just a best practice—it’s a necessity. By leveraging Bitbucket and AWS, you can automate your development workflows, reduce human error, and expedite the deployment of new features and services.
