DevOps in practice for beginners

Learn about the principles, methodologies, and tools that can help you build & operate your applications. Throughout demos, learn about case studies & industry best practices. Discover the importance of Infrastructure as Code, CI/CD, Continuous Configuration, and Observability and Monitoring

This session is designed as a journey. We will start with real world example of building serverless APIs. Then, we will continue to implement IaC and CI/CD for multiple environments using Continous Delivery with manual approval. We will also walkthrough how you can implement feature flags by using Continous Configuration. Lastly, we will review how to implement Observability and Monitoring to understood what’s happening under the hood of the application.

Converting existing resources into IaC AWS CLOUDFORMATION IAC GENERATOR The IaC generation process consists of several steps: 1. Start a scan of your account. 2. Create a template 3. Add scanned resources 4. Import the resources to be managed by CloudFormation as a stack or migrate them into an AWS CDK app. AWS CloudFormation AWS Resource s IaC Generator Template s Deploy
