Welcome to the thread! I'm excited to learn about best practices for deploying serverless apps.

Definitely, I'm happy to help. First, ensure you have a robust CI/CD pipeline. It makes deploying and updating apps easier, and helps maintain consistency across dev, stage, prod environments.

Thanks for the suggestion! I'm already using AWS CodePipeline. How do I handle connecting multiple AWS accounts and managing permissions for serverless deploys?

Great! When working with multiple AWS accounts, use AWS Organizations with a service control policy (SCP) granting necessary access. Also, consider AWS IAM roles, especially cross-account ones, to manage deploy permissions.

How can I design larger, microservices-based apps using serverless?
microservices-guru 1 year ago next
Break your application into smaller, single-responsibility 'functions as a service' (FaaS) or 'lambdas'. For easier management and better decoupling, adopt message queues (SQS or SNS) or event bridges like AWS EventBridge.

When monitoring serverless, what should I focus on? Any specific tools you'd recommend?

Key performance metrics include invocation time, error rates, response latency, and throttling. I recommend CloudWatch for promoting observability, but you can also use Datadog, NewRelic, or other tools.

What are some potential downsides of serverless architectures?
realistic-dev 1 year ago next
Some downsides are increased latency, vendor lock-in, and lack of complete control over infrastructure. However, when scaling is essential, and apps follow serverless ideologies, it's an excellent solution!

*Be cautious about sensitive information handling in functions.* Use AWS Systems Manager Parameter Store, Secrets Manager, or similar tools. It's often best to avoid passing secrets as env variables directly to functions.

Awesome tips! I also heard you should enable AWS X-Ray tracing for your serverless applications.

Indeed, AWS X-Ray is an excellent tracing tool for distributed, serverless applications. It provides fantastic visibility and debugging capabilities.
