5. This is what actually means... serverless
8. Serverless is about the of servers. Build and run applications servers. management without thinking about
9. But: Serverless is NoOps! You still have to deal with things like: Monitoring, Metrics, State, Dependencies, Deployment, Debugging, Network, ... not
10. You are still for the (end) results! Keep in mind! No ops cost != no cost of ownership! responsible DevOps
11. OF COMPUTING Physical Servers in datacenters Virtual Machines in datacenters Virtual Machines in Cloud Containers on Virtual Machines Serverless as the unit of compute EVOLUTION
16. COMPUTE Functions are the unit of deployment and scaling. No machines, VMs, or containers visible in the programming model. Permanent storage lives elsewhere. Scales per request; Users cannot over- or under-provision capacity. Never pay for idle (no cold servers/containers or their costs). Implicitly fault-tolerant because functions can run anywhere. BYOC - Bring Your Own Code. Metrics and logging are a universal right. SERVERLESS MANIFESTO
17. ? Unit of deployment and scale! PaaS FaaS PAAS vs.
18. SERVERLESS BLOCKS BUILDING
19. WHAT IS SERVERLESS FOR? Prototyping Not latency-sensitive apps Async apps Simple state models GOOD
20. COMMON SERVERLESS CASES USE
21. AWS Event Driven JVM-based languages (Java 8), JavaScript (Node.js), Python, C#, (more to come) Versions, Step Functions, Encrypted Environment Variables Pay as you use - in 100ms blocks (e.g. 100ms w/ 128MB memory = USD 0.000000208) LAMBDA
22. AWS EVENTS S3 Cloud Watch Config AWS IoT Cognito SES API Gateway (no complete list) LAMBDA DynamoDB Cloud Formation Kinesis Code Commit SNS Echo / Alexa Cron
23. GATEWAY "Reverse Proxy" HTTPS interface for Lambda functions and other services Authorization Model validation Caching, Throttling, DDoS attack protection, etc. API
24. DYNAMO Fully Managed NoSQL Data Store Schemaless Data Model DynamoDB Streams Record TTL Seamless Scalabiltiy, "no limits" Pay by Read-/Write-Capacity-Units and used storage, not by time DB
25. MEET AWS erverless pplication odel CloudFormation extension SAM S A M
26. THE FRAMEWORK Manages all the Cloud-Resources and Deployment. SERVERLESS serverless.com
27. COMPETITORS?
28. Provider since Environment AWS Lambda 2014 JavaScript, Python, Java, C# Microso AzureFunctions 2016 JavaScript, Python, Java, C#, PHP Google CloudFunctions 2016 JavaScript IBM Bluemix w/ OpenWhisk* 2014 JavaScript, Python, Swi * Apache OpenWhisk is also available for on-premise usage as OSS under ASL2 COMPETITORS
29. BUT POWERFUL No need to run/manage Application Servers Fast results, minimal effort, minimal TTM(!) Low costs, minimal financial risk Automatic Scalabiltiy and Availability "out-of-the-box" SERVERLESS
