- 2. Why Serverless? • DevOps is too hard • developers don’t want to have to do the “ops” bit ==> NoOps • Lean Startups • want to prove a business idea quickly & cheaply • Because you can • new serverless offerings in the market from big platforms to small startups • Scale and Cost • Autoscaling built in • Pay per call (never pay for idle)
- 3. Global Drivers for Serverless • Cloud - is now mainstream, easy and cheap • Microservices - gaining adoption • Digital Business - technicians and business working together in integrated teams to digitise their business and deliver value
- 5. API Serverless Products • Design an API • Attach to cloud-based data store • Add business logic • Publish • Manage consumers https://medium.com/@APIdays/mapping-the-api-serverless-market-landscape-1d27d72ffc8d#.3g5xyxtco
- 6. E.g. Restlet • Simple BaaS • Create a Datamodel • It will generate a REST-ish API for you • YAML, JSON, XML • Swagger documentation • SDKs • shell, node, java, python, php, objective-c, go
- 9. API CRUD Makers • Transform data sets into APIs • Structured • Unstructured • CRUD https://medium.com/@APIdays/mapping-the-api-serverless-market-landscape-1d27d72ffc8d#.3g5xyxtco
- 10. API Funnels • Aggregate multiple APIs into one https://medium.com/@APIdays/mapping-the-api-serverless-market-landscape-1d27d72ffc8d#.3g5xyxtco
- 11. Creation tools and frameworks • Create and link APIs in the cloud • Serverless Applications https://medium.com/@APIdays/mapping-the-api-serverless-market-landscape-1d27d72ffc8d#.3g5xyxtco
- 12. Squirrelbin Architecture • Angular SPA • Hosted on S3 • REST API • CRUD Lambda Functions • Storage in dynamoDB • Execute acorns in Lambda
- 13. Zombie Survivor Chat • Decoupling • separate lambda functions for search, chat and activity services • Separate data stores • dynamoDB • Data transformations in API Gateway • Early transformation -> common back-end logic • Security – service isolation & least privilege • Dev Lifecycle • Separate environments • Mocks for early APIs • CloudFormation to stitch it all together
- 14. Serverless Framework • Node.js application • Generates CloudFormation templates • You author a REST-ish API and associated functions • It deploys to AWS • Configures Lambda Functions • Configures API Gateway endpoints
- 15. Sparta Framework • Serverless for golang
- 16. Is Serverless a natural step?
- 17. What is serverless really good for? • Proof of concept • Lean startup • Event-driven applications • IoT • Data analytics
