15. Zašto Cloud Infrastruktura? Uvećana Agilnost i performanse Skoro neograničena skalabilnost Uvećana pouzdanost Niži troškovi Maksimalna Sigurnost

21. Šta je AWS? Sve što postoji, a da je bitno u Vašem Datacentru
23. Customer obsessed našeg roadmapa dolazi od zahteva klijenata 90%
24. Globalna Platforma AWS globalna infrastruktura • 24 AWS Regions with 76 Availability Zones • 5 new AWS Regions coming soon: Indonesia, Italy, Japan, South Africa, Spain • 16 new AZs planned 216 CloudFront PoPs • 205 edge locations • 11 regional edge caches • 84 cities across 42 countries AWS globalna mreža • Redundant 100 GbE network • 100% encrypted between facilities • Private network capacity between all AWS Regions except China
25. A šta ja to tačno mogu u Cloudu?
26. Amazon EC2 Virtual servers in the cloud Physical servers in AWS global Regions Guest 1 Guest 2 Guest n Hypervisor Host server EC2 instances
27. Amazon Aurora Amazon RDS Amazon DynamoDB Amazon DocumentDB Amazon Timestream Amazon Neptune Amazon ElastiCache Amazon QLDB Purpose-built databases
28. Amazon S3 Durable, available, exabyte-scalable Secure, compliant, auditable High performance Low-cost storage and analytics Broad network integration Amazon S3 AWS Lake Formation & AWS Glue AWS Snowball Amazon Kinesis Data Streams AWS Snowmobile Amazon Kinesis Data Firehose Amazon Redshift Amazon EMR Amazon Athena Amazon Kinesis Amazon Elasticsearch Service Amazon SageMaker Amazon Comprehend Amazon Rekognition

33. Tradicionalna three-tier application arhitektura Web servers Presentation layers Application servers Business logic Database servers Data layer
34. Moderna three-tier application arhitektura Presentation Business logic Data Queues/messages Events Events APIs
35. APIs are the front door of microservices
36. Events are the connective tissue of modern applications
37. A decoupled data strategy improves fault tolerance
38. Decoupling state from servers improves resilience and handles error cases better
40. Queues/messages Events Events APIs

42. Computing evolution – A paradigm shift LEVEL OF ABSTRACTION FOCUS ON BUSINESS LOGIC PHYSICAL MACHINES Requires “guess” planning Lives for years on-premises Heavy investments (capex) Low innovation factor Deploy in months
43. Computing evolution – A paradigm shift LEVEL OF ABSTRACTION FOCUS ON BUSINESS LOGIC VIRTUAL MACHINES Hardware independence Faster provisioning speed (minutes/hours) Trade capex for opex More scale Elastic resources Faster speed and agility Reduced maintenance
44. Computing evolution – A paradigm shift LEVEL OF ABSTRACTION FOCUS ON BUSINESS LOGIC CONTAINERIZATION Platform independence Consistent runtime environment Higher resource utilization Easier and faster deployments Isolation and sandboxing Start speed (deploy in seconds)
45. Computing evolution – A paradigm shift AWS Lambda AWS Fargate LEVEL OF ABSTRACTION FOCUS ON BUSINESS LOGIC Continuous scaling Fault tolerance built-in Pay for value Zero maintenance SERVERLESS
46. Serverless znači?
47. Šta je Bezserverje? No infrastructure to manage Automatic scaling Pay for value Highly available and secure
48. Serverless != just FaaS
49. AWS Lambda AWS Fargate Amazon API Gateway Amazon SNS Amazon SQS AWS Step Functions COMPUTE DATA STORES INTEGRATION AWS AppSync Amazon Aurora Serverless Amazon S3 Amazon DynamoDB Amazon EventBridge

52. Mobile application
53. Data Processing
54. Positive Chat – Serverless architecture Amazon DynamoDB Amazon Cognito Amazon API Gateway WebSocket connection PositiveChat Lambda function Connections table Conversations table Topics table Web browser AWS Cloud S3 bucket for static assets (HTML, CSS, JS) Authentication Authorization To be implemented Amazon Comprehend Amazon Translate Amazon Rekognition To be implemented https://github.com/danilop/serverless-positive-chat

59. Malo knjiga Full Stack Serverless by Nader Dabit Running Serverless by Gojko Adžić
60. “Create application” experience Create a serverless application from a starter template • AWS SAM template for IaC • CI/CD pipeline • Clone locally for development with AWS SAM CLI
