URL: readysetcloud.io

Practice Verified Codes and Commands:

1. AWS Lambda Deployment using AWS CLI:

aws lambda create-function --function-name my-function \
--zip-file fileb://function.zip --handler index.handler \
--runtime nodejs14.x --role arn:aws:iam::123456789012:role/lambda-execution-role

2. Serverless Framework Deployment:

serverless deploy --stage dev --region us-east-1

3. AWS CloudFormation Template for Serverless Architecture:

Resources:
MyLambdaFunction:
Type: AWS::Lambda::Function
Properties:
Handler: index.handler
Role: arn:aws:iam::123456789012:role/lambda-execution-role
Code:
S3Bucket: my-bucket
S3Key: function.zip
Runtime: nodejs14.x

4. AWS SAM CLI for Local Testing:

sam local invoke MyFunction --event event.json

5. AWS DynamoDB Table Creation:

aws dynamodb create-table \
--table-name MyTable \
--attribute-definitions AttributeName=ID,AttributeType=S \
--key-schema AttributeName=ID,KeyType=HASH \
--provisioned-throughput ReadCapacityUnits=5,WriteCapacityUnits=5

6. AWS API Gateway Integration with Lambda:

aws apigateway create-rest-api --name 'My API'

7. AWS S3 Bucket Creation:

aws s3api create-bucket --bucket my-bucket --region us-east-1

8. AWS CloudWatch Logs Setup:

aws logs create-log-group --log-group-name /aws/lambda/my-function

9. AWS IAM Role Creation for Lambda:

aws iam create-role --role-name lambda-execution-role \
--assume-role-policy-document file://trust-policy.json

10. AWS SNS Topic Creation for Notifications:

aws sns create-topic --name my-topic

What Undercode Say:

The article “The Ready, Set, Cloud Serverless Picks of the Week #151” highlights the importance of serverless architecture in modern cloud computing. Serverless computing allows developers to build and run applications without managing the underlying infrastructure, enabling faster development cycles and cost efficiency. AWS Lambda, a key player in the serverless ecosystem, allows you to run code in response to events without provisioning or managing servers.

To get started with serverless, you can use the AWS CLI to deploy Lambda functions, create DynamoDB tables, and set up API Gateway integrations. The Serverless Framework simplifies deployment and management, while AWS SAM CLI enables local testing and debugging.

For monitoring and logging, AWS CloudWatch provides insights into your serverless applications, ensuring optimal performance and troubleshooting. IAM roles are essential for granting permissions to your Lambda functions, while SNS topics can be used for notifications and event-driven architectures.

If you’re new to serverless, start with simple use cases like file processing or API integrations. As you gain confidence, explore advanced topics like step functions, event sourcing, and formal methods for verifying serverless workflows.

For further reading, check out Marc Brooker’s blog on formal methods in serverless computing: Marc’s Blog.

Serverless is not just a trend; it’s a paradigm shift in how we build and deploy applications. Embrace it, experiment with it, and leverage its full potential to stay ahead in the cloud-native world.
