    Essential Interview Questions for Serverless Developer

    How familiar are you with the serverless offerings from cloud providers prevalent in Switzerland, such as AWS, Azure, or Google Cloud?

    I have hands on experience with AWS Lambda, Azure Functions, and Google Cloud Functions. I have used them to build APIs, process data streams, and automate infrastructure tasks. I am aware of the nuances of each platform regarding scaling, security, and integration with other services offered in Switzerland.

    Describe your experience with Infrastructure as Code (IaC) tools like Terraform or CloudFormation, and how you've used them to manage serverless infrastructure.

    I have extensive experience using Terraform to define and manage serverless infrastructure. I have used it to create repeatable, version controlled deployments of AWS Lambda functions, API Gateways, and other resources. I understand how to use Terraform to automate infrastructure changes, ensuring consistency and reducing the risk of errors in the Swiss context.

    Can you explain your approach to monitoring and logging in a serverless environment, and which tools or services you've used for this purpose?

    For monitoring and logging serverless applications, I have used tools like AWS CloudWatch, Azure Monitor, and Datadog. I implement structured logging practices to ensure that logs are easily searchable and analyzable. I also set up alerts based on key performance indicators to proactively identify and address issues within applications operating in Switzerland.

    How do you handle security considerations in serverless applications, such as authentication, authorization, and data protection?

    Security is a primary concern when building serverless applications. I implement authentication and authorization using services like AWS Cognito or Azure Active Directory.
