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 ⢠CEO Ortus Solutions ⢠Computer Engineer ⢠Born in El Salvador => Raised in the USA ⢠2023 Leading EU Expansion team (Malaga, Spain đŞđ¸) ⢠Creator & Maintainer: ColdBox MVC, TestBox BDD/TDD, CommandBox CLI, ContentBox CMS, etc. ⢠Creator / Chief Language Engineer BoxLang Programming Language @lmajano @ortussolutions
- 3. ⢠Serverless ⢠What? Why? When? ⢠Providers ⢠Use Cases ⢠Real Life Case ⢠Best Practices Agenda ⢠BoxLang ⢠Lambda Runtime ⢠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 ⢠API Driven Patterns ⢠Event Driven Patterns ⢠Data Streaming Patterns ⢠Scheduling Patterns
- 8. Key Points about Serverless ⢠Me ⢠Focus on code abstractions ⢠Provider ⢠Auto Scaling ⢠Fault tolerance ⢠High Availability ⢠Metrics and Logging ⢠No OS updates ⢠Pay per use ONLY
- 9. Fine-Grained Pricing: Never pay for idle ⢠FREE Tier ⢠Buy in 100ms increments ⢠No minimums ⢠No per-device fees ⢠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 âŚ. 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? ⢠try.boxlang.io ⢠Internet playground for BoxLang ⢠First production BoxLang applications ⢠Powered by our MiniServer and AWS Lambda Runtimes
- 22. Cool Stats ⢠Average executions per day: 32,000+ ⢠Average execution time: 32ms ⢠Monthly Bill ???? $0.0000000000
- 23. AWS Lambda Best Practices ⢠Code is stateless ⢠Leverage external services: S3, ElastiCache, RDS, etc. ⢠Ephemeral Disk Capacity ⢠512MB by default -> 10GB if needed (But you pay) ⢠Max Timeout = 15 Minutes, lower it to your convenience, or pay for it :)
- 24. AWS Lambda Best Practices ⢠Concurrent Executions: 1000 ⢠Beware the ColdStart ⢠Use static constructs to avoid re-creations per request ⢠Payload Size (Careful Here) ⢠Request: 6MB Synchronous, 256KB asynchronous ⢠Response: 6MB
- 25. Logging & Metrics ⢠USE IT! Itâs already included ⢠Enable X-Ray + Lambda Service Traces ⢠Enable Enhanced Monitoring ⢠A wealth of debugging data is available!
- 26. Deployment Limits ⢠50 MB zip or jar fi le ⢠250MB unzipped ⢠Up to 5 Layers (Dependency Jars) ⢠Recommendations: ⢠Create a Fat/Shaded Jar ⢠Use Container Images -> 10GB ⢠Use our BoxLang Template! ⢠But, remember, focused work units is what you want.
- 27. Power Levels ⢠Had no idea at fi rst! ⢠You donât choose CPU, you choose the memory ⢠More Memory => More CPU you get ⢠From 128bm => 10GB in 1GB increments ⢠Want to save money? Choose ARM and not x86, way cheaper! ⢠Geek way to save money? AWS Lambda Power Tuning: https://github.com/alexcasalboni/aws-lambda-power-tuning
