0 likes8 views
Unlock the full potential of cloud computing with BoxLang! đ Discover how BoxLangâs modern, JVM-based language streamlines development, enhances productivity and simplifies scaling in a serverless environment, Led by Luis Majano, the creator of BoxLang and Ortus Solutions CEO! In this session, weâll explore the fundamentals of AWS Lambda, Amazonâs powerful serverless computing service that lets you run code without provisioning or managing servers. Youâll understand what AWS Lambda is, how it works, and why itâs a game-changer for building scalable, cost-effective applications. Weâll then dive into BoxLang, a modern, JVM-based language designed to streamline development in the cloud. Youâll see firsthand how easy it is to write and deploy Lambda functions using BoxLang, making the process more intuitive and efficient. Whether youâre new to serverless or an experienced developer, this session will equip you with the knowledge and tools to build dynamic, high-performance serverless applications. We will also discover how https://try.boxlang.io was built using these technologies and how easily you can build, scale, and deploy serverless applications.

June Webinar: BoxLang-Dynamic-AWS-Lambda
- 1. Dynamic AWS Lambda with LED BY Luis F. Majano
- 2. LUIS F. MAJANO âą CEO Ortus Solutions âą Computer Engineer âą Born in El Salvador => Raised in the USA âą 2023 Leading EU Expansion team (Malaga, Spain đȘđž) âą Creator & Maintainer: ColdBox MVC, TestBox BDD/TDD, CommandBox CLI, ContentBox CMS, etc. âą Creator / Chief Language Engineer BoxLang Programming Language @lmajano @ortussolutions
- 3. âą Serverless âą What? Why? When? âą Providers âą Use Cases âą Real Life Case âą Best Practices Agenda âą BoxLang âą Lambda Runtime âą Lambda Template Part 1 Part 2
- 4. AWS Lambda - Serverless Computing FaaS
- 5. AWS Lambda is a serverless computing service that runs code in response to events without managing servers, automatically scaling and charging only for execution time. What is serverless?
- 6. Serverless Computing Evolution Physical Machines Virtual Machines Containers Lambdas Focus on Business Logic Abstraction
- 7. Execution Patterns âą API Driven Patterns âą Event Driven Patterns âą Data Streaming Patterns âą Scheduling Patterns
- 8. Key Points about Serverless âą Me âą Focus on code abstractions âą Provider âą Auto Scaling âą Fault tolerance âą High Availability âą Metrics and Logging âą No OS updates âą Pay per use ONLY
- 9. Fine-Grained Pricing: Never pay for idle âą FREE Tier âą Buy in 100ms increments âą No minimums âą No per-device fees âą No idle fees
- 10. How Functions Work Upload Function (CI, Manually) De fi ne Function Triggers (API Calls, Events, Schedules) Function Execution (Stateless, Cold Start, Timeouts)
- 13. Core Concept of Serverless is âŠ. Function = Unit of Work
- 14. Common Use Cases REST Data Processing Chat Bots Amazon Alexa IoT Scheduled Tasks Code Execution AI
- 16. REST (Direct Function URL or API Gateway)
- 17. Event Handling
- 18. Scheduling with AWS EventBridge
- 19. Ortus Use Case : BoxLang Code Playground : try.boxlang.io
- 20. Wanna play? 64MB RAM 600 KB 8 MB <Your Code>
- 21. Wanna play? âą try.boxlang.io âą Internet playground for BoxLang âą First production BoxLang applications âą Powered by our MiniServer and AWS Lambda Runtimes
- 22. Cool Stats âą Average executions per day: 32,000+ âą Average execution time: 32ms âą Monthly Bill ???? $0.0000000000
- 23. AWS Lambda Best Practices âą Code is stateless âą Leverage external services: S3, ElastiCache, RDS, etc. âą Ephemeral Disk Capacity âą 512MB by default -> 10GB if needed (But you pay) âą Max Timeout = 15 Minutes, lower it to your convenience, or pay for it :)
- 24. AWS Lambda Best Practices âą Concurrent Executions: 1000 âą Beware the ColdStart âą Use static constructs to avoid re-creations per request âą Payload Size (Careful Here) âą Request: 6MB Synchronous, 256KB asynchronous âą Response: 6MB
- 25. Logging & Metrics âą USE IT! Itâs already included âą Enable X-Ray + Lambda Service Traces âą Enable Enhanced Monitoring âą A wealth of debugging data is available!
- 26. Deployment Limits âą 50 MB zip or jar fi le âą 250MB unzipped âą Up to 5 Layers (Dependency Jars) âą Recommendations: âą Create a Fat/Shaded Jar âą Use Container Images -> 10GB âą Use our BoxLang Template! âą But, remember, focused work units is what you want.
- 27. Power Levels âą Had no idea at fi rst! âą You donât choose CPU, you choose the memory âą More Memory => More CPU you get âą From 128bm => 10GB in 1GB increments âą Want to save money? Choose ARM and not x86, way cheaper! âą Geek way to save money? AWS Lambda Power Tuning: https://github.com/alexcasalboni/aws-lambda-power-tuning
- 28. SAM - Your new Best Friend âą Template-Driven resource management model âą Fancy words for Infrastructure as Code âą Supports anything AWS âą Included CLI âą Great for testing locally https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/install-sam-cli.html
