Development in the could: How do we do it(Cloud computing. Microservices. Faas)
0 likes510 views
The document discusses the evolution of cloud computing, highlighting the transition from physical servers to serverless function-as-a-service (FaaS) deployments. It emphasizes the significance of cloud-native applications, their antifragile nature, and the benefits of microservices and orchestration in development and scaling. Additionally, it touches on the rise of PaaS ecosystems and the necessity of rapid deployment for competitive advantage in the market.

Development in the could: How do we do it(Cloud computing. Microservices. Faas)
- 1. DEV IN CLOUD: HOW WE ARE DOING IT Dmytro Voloshyn, co-founder at Programmer 8+ years Marketing manager in AB-InBev 2+ years Consulting projects, outsource, sales 2+ years Сo—founder&CTO at Preply, 4+ years and now
- 3. “Cloud is about how you do computing, not where you do computing” — Paul Maritz, CEO oF VMware
- 4. Trends Serverless(FaaS) Cloud Native Applications PaaS ecosystems, SaaS’s rise
- 6. Deployment evolution Rent/Buy Physical server Snowflake server Deploy in days Live for years Rent a virtualised cloud server EC2 Deploy in minutes Live for weeks Containerised deployment Docker Deploy in seconds Live for hours Serverless FaaS(eg. Lambda) Deploy in milliseconds Live for seconds
- 7. Chatbot :)
- 8. AWS Lambda
- 10. Function as a unit of application logic Side effects, pure functions, real-life example Machine Assembly Procedural Object oriented Functional
- 11. SaaS -> PaaS -> IaaS -> BaaS -> FaaS
- 12. Faster scaling, #NoOps, Less$,
- 13. Amazon AWS Lambda, Google Cloud Functions, and Windows Azure Functions
- 15. Cloud Native Applications Antifragile Pay as you go (pricing on demand) Hyper scaling (traffic, data, features) Continuous Delivery (DevOps)
- 16. Antifragile Everything fails all the time Focus on MTTR not MTTF 8 fallacies
- 17. Pay as you go Provisioned vs. OnDemand Fixed servers vs. resource pooling #NoDevOps
- 19. Continuous Delivery Diagnosability: traces, metrics, logs Automate tasks, scripts Automated delivery
- 24. Treat resources as cattle not pets VS.
