This document summarizes serverless computing platforms and their strengths and weaknesses. It discusses how serverless platforms take over traditional server roles and how coding is simplified with services for scaling, monitoring, recovery and logging included. While deployment and recovery are very quick, latency and lack of strong SLAs are weaknesses. The document also outlines opportunities like skipping technology upgrades, and threats like vendor lock-in. Key components discussed are AWS Lambda, API Gateway and DynamoDB along with examples like a serverless tank game and Python frameworks.

3. 4 Amazon AWS Lambda
4 Google Cloud Services
4 Microsoft Azure Functions
4 IBM Open Whisk

4. Code with batteries included
4 Scaling
4 Monitoring
4 Recovery
4 Versioning
4 Logging

5. Traditional roles of servers taken over
by the platform

6. 4 Gatekeeper -> Distributed Auth
4 Scaling point -> Containers
4 Orchestration -> Client or workflow engines

7. Strengths
4 Time to deploy minimal
4 Time to recover irrelevant
4 Multi-versioned
4 Forces small, isolated code modules
4 Fine-grained, transparent, cost of operation
4 Use readily-available services built for massive scale

8. Weaknesses
4 No strong SLAs yet
4 Latency
4 No PCI compliance
4 No way to keep open connections
4 Requires complete rethink on many common
practices
4 Configuration becomes a challenge

9. Opportunities
4 Skip a generation of technology/process upgrades
4 Rethink architectural and operational "best
practices"
4 Change billing models
4 Marketplaces for digital services
4 Fine-grained monitoring and optimisation
4 A/B testing throughout

10. Threats
4 Vendor lock-in (not code, but services)
4 High reliance on external parties

11. Key components
4 AWS Lambda - execute code
4 API Gateway - HTTP endpoint
4 DynamoDB - Storage (optional)
