Some examples are: 1. **Complexity**: Managing multiple services increases the overall system complexity, making development, deployment, and monitoring more challenging (as there are more “moving parts”). 2. **Service Communication**: Ensuring reliable communication between services, handling network latency, and dealing with issues like service discovery and API versioning can be difficult.

Managing data consistency and transactions across distributed services is complex, often requiring techniques like eventual consistency and distributed databases. 4. **Deployment Overhead**: Coordinating the deployment of multiple services, especially when they have interdependencies, can lead to more complex CI/CD pipelines. 5. **Monitoring and Debugging**: Troubleshooting issues is harder in a microservices architecture due to the distributed nature of the system. Trying to figure out where the information goes and which services are involved in a single request can be quite a challenge for large platforms. This makes debugging microservices architecture a real headache. 6. **Security**: Securing microservices involves managing authentication, authorization, and data protection across multiple services, often with varying security requirements. \ No newline at end of file diff --git a/src/data/question-groups/devops/content/popular-cicd-tools.md b/src/data/question-groups/devops/content/popular-cicd-tools.md index 5726c1577..ddc65df54 100644 --- a/src/data/question-groups/devops/content/popular-cicd-tools.md +++ b/src/data/question-groups/devops/content/popular-cicd-tools.md @@ -14,6 +14,7 @@ These tools allow you to install them on your own infrastructure and don’t req On the other hand, these tools either require you to use them from the cloud or are only accessible in SaaS format, which means they provide the infrastructure, and you just use their services.

Understand how these concepts contribute to the overall development lifecycle. 2. **Practice hands-on skills**: There is a lot of practical knowledge involved in the DevOps practice, so make sure you try what you read about. Set up some CI/CD pipelines for your pet projects, understand containerization, and pick a tool to get started. The more you practice, the more prepared you’ll be for real-world problems. 3. **Study software architecture**: While you may not have the responsibilities of an architect, having a solid understanding of software architecture principles can be a huge help. Being able to discuss the different components of a system with architects would make you a huge asset to any team. 4. **Research the Company**: In general, it’s always a great idea to research the company you’re interviewing for. In this case, investigate the company’s DevOps practices, the technologies they use, and their overall approach to software development. This will help you demonstrate a genuine interest in their operations and come prepared with thoughtful questions.
