AWS Community Key Takeaways Understand the key reasons of adopting serverless services to run your architecture and essential serverless services you need to use. 

What is serverless? 

AWS Community What is serverless? Automatic scaling Highly available and secure Pay for use No infrastructure provisioning, no management 

AWS Community There’s a paradigm shift happening 5 Level of abstraction Focus on business logic Serverless Physical machines Virtual machines Containerization AWS Lambda AWS Fargate • Continuous scaling • Fault tolerance built-in • Pay for value • Zero maintenance • Focus on business value 

AWS Community 6 What does the future look like? ALL THE CODE YOU EVER WRITE IS BUSINESS LOGIC 

Reason #1: No Server Management 

AWS Community AWS operational responsibility models Compute Virtual machine Amazon EC2 AWS Elastic Beanstalk Lambda Fargate Databases MySQL MySQL on Amazon EC2 Amazon RDS for MySQL Amazon RDS Amazon Aurora DynamoDB Storage Storage S3 Messaging ESBs Amazon MQ Amazon Kinesis EventBridge/SQS/SNS Analytics Hadoop Hadoop on EC2 EMR Amazon OpenSearch Service Amazon Athena Less More 

AWS Community 9 AWS Lambda — Event-driven function Event Source Function Services / Other Changes in data state Requests to endpoints Changes in resource state Node.js Python Java C# Go Ruby Bring Your Own 

AWS Community Anatomy of a Lambda Function 10 Handler function • Function executed on invocation • Processes incoming event Event • Invocation data sent to function • Shape differs by event source Context • Additional information from Lambda service • Examples: request ID, time remaining app.py 

Reason #2: Get to Market, Fast and Secure 

AWS Community AWS Lambda AWS Fargate Amazon API Gateway Amazon SNS Amazon SQS COMPUTE DATA STORES INTEGRATION Amazon Aurora Serverless Amazon S3 Amazon DynamoDB Amazon EventBridge STREAMING Amazon Managed Streaming for Apache Kafka (MSK) Amazon Kinesis Amazon MQ 

AWS Community IAM Role for AWS Lambda 

Reason #3: Effective Scaling and Cost Efficient 

AWS Community Auto Scaling for Amazon DynamoDB 

AWS Community AWS Lambda: Fine-grained pricing • Pay for value • Priced by power rating • Charged in 1ms increments • Low per-request charge • No minimum • Never pay for idle Free Tier 1M requests and 400,000 GBs of compute. Every month, every customer. 

Reason 4: Flexible and Seamless integrations 

AWS Community Small pieces, loosely joined 

AWS Community Trigger Configuration — AWS Lambda 

Reason 5: Faster Response with Events 

AWS Community Change Data Capture for DynamoDB Streams 

AWS Community Event-driven architectures drive reliability and scalability Asynchronous Events Improve responsiveness and reduce dependencies Event Routers Abstract producers and consumers from each other Event Stores Buffer messages until services are available to process

AWS Community Event-driven Architecture in Serverless Microservices 

Wrapping up! 

AWS Community Why serverless? • What is serverless? Serverless as operating model • Focus on products, not infrastructure • Reason #1: No server management • Reason #2: Get to market, fast and secure • Reason #3: Effective scaling and cost efficient • Reason #4: Flexible and seamless integrations • Reason #5: Faster response with Event-Driven • Serverless fits various use cases, i.e. IT Automation, Microservices, Data processing, Serverless frontend/backend, Architectural patterns
