The future of cloud programming
1 like477 views
The document discusses the future of cloud programming, emphasizing serverless and concurrent programming with frameworks like AWS Lambda and Azure Cloud Functions. It outlines the benefits and challenges of functional programming, serverless architecture, and backend as a service (BaaS), highlighting scalability, deployment processes, and resource limitations. It concludes with a comparison of serverless and BaaS, focusing on their efficiency, cost-effectiveness, and the importance of centralized databases.
The future of cloud programming
- 1. The Future of Cloud Programming Is Serverless and Concurrent
- 2. What’s this all about? Concurrent Programming Erlang, Java Go, Elixir, Scala Serverless Architecture AWS Lambda Azure Cloud Functions Backend as a Service (Baas) Google Firebase
- 3. Concurrency Doing a lot of things at once
- 4. The Basics ● Utilize multi-core systems ● Scale across multiple servers ● Low latency
- 5. Complications ● Hard to develop ● Hard to debug ● Different mindset ● Fewer developers
- 6. Benefits of Functional Programming ● Super Fast ● Fewer Bugs ● Easy to Test ● Concurrent by Default
- 7. 2 Million Websocket Connections On a SINGLE SERVER
- 8. The Future ● Better Languages ○ Elixir ○ Clojure ○ Scala ○ Go ● Strong VMs ○ JVM ○ Erlang VM ● More prolific
- 9. Serverless Functions as a Service (FaaS)
- 10. How it Works ● No Servers * ● Host provides resources ● Resources are on demand ● Function is executed
- 11. Advantages ● Scalability ● Cost ● Programming Model ● Deployment Process ● Reliability ● Throughput
- 12. MLB Statcast 30 JSON docs / second / game ~1k - 50k / JSON
- 13. Disadvantages ● Limited resources ● Short execution time ● Hard to debug ● Slow when unused ● Hard to monitor ● Hard to replicate
- 16. BaaS “Backend as a Service” - or - “How to stop worrying and love the cloud”
- 17. How it Works MAGIC!
- 18. Google someone hosts and maintains a centralized database How it Works
- 19. Advantages ● Centralized DB ● Near Real Time ● Updated by Multiple Users ● Cross Platform API ● Hosting Included (required)
- 20. Disadvantages ● Centralized DB ● Hosting Included (required) ● May be overkill ● Expensive at scale ● Not SQL (JSON)
- 22. Review Concurrency ● Functional Programming ● Low Latency ● High Scale ● Maximize Resources Serverless ● High Throughput ● Low Cost ● High Scale ● Frequent small tasks BaaS ● Rapid Development ● Prototyping ● Near Real Time ● Central DB ● Frequent Updates
