AWS provides a platform that is ideally suited for deploying highly available and reliable systems that can scale with a minimal amount of human interaction. This talk describes a set of architectural patterns that support highly available services that are also scalable, low cost, low latency and allow for agile development practices. We walk through the various architectural decisions taken for each tier and explain our choices for appropriate AWS services and building blocks to ensure the security, scale, availability and reliability of the application.

9. Now how to build this….

10. AWS Elastic Beanstalk
• AWS Elastic Beanstalk allows for automated deployment of applications by
configuring its run-time environment (inside the AMI)
– Upload your application package
– Beanstalk handles the deployment details of capacity provisioning, load balancing,
auto-scaling, application health monitoring, and DNS CNAME
• Environment is available in minutes at a customized URL
(e.g. http://myapp.elasticbeanstalk.com/)
• Elastic Beanstalk supports ASP.Net, Java, Node.Js, PHP, Python & Ruby
• Think about it as a managed runtime or “Container as a Service”

22. Web Application Session State

23. Session State Considerations for Scaling Out
• ASP.Net uses a provider model to enable pluggable providers (DLLs) and settings in the
Web.Config file
• In-Proc : in memory on the web server (default OOBE)
• Out-of-Proc : on another server ß Need this for “Scale Out”
– Usually Microsoft SQL Server on a dedicated server
• AWS provides additional Session State Options:
1. MySQL data provider via RDS (3rd party on Codeplex)
2. MemcacheD (aka ElastiCache)
3. AWS DynamoDB
AWS Blog Managing ASP.Net Session State With DynamoDB : http://bit.ly/1k0DeVz

24. Dynamo DB
• DynamoDB is a very fast, managed NoSQL database as a service
• Designed to store and retrieve any amount of data, and serve virtually any
level of traffic with automatic sharding it linearly scalable
– Dial in the number of read and writes per second as needed by application
• All data items are stored on Solid State Drives (SSDs), replicated across 3
Availability Zones for high availability and high durability
• DynamoDB offloads the administrative burden of operating and scaling a
highly available distributed database cluster

25. AWS SDK via NuGet in Visual Studio
" Pre-packaged NuGet AWS tools can be installed to provide DynamoDB Session State Support

26. Changes to Web.Config file to enable
AWS DynamoDB Session State
" Security Tip: Create a custom IAM user to only allow access to DynamoDB

27. Static Content

28. Static Web Content Management Strategy
• Static Content usually resides on the same web server as dynamic web
content
– E.g.. Jpegs, CSS, JS, GIFs etc
• Moving static content to dedicated “static content servers” can reduce
server loads
• On AWS this means smaller instances for EC2 and lower hourly cost
and using Simple Storage Service (S3)
• By using Route 53 DNS this can be changed without web application
disruption

29. Application HTML References to Static Assets
• Edit HTML content directly to reference fully qualified domain name to let
DNS resolve origin servers; OR
• Use Content Rewrites in the web server
– E.g. ASP.Net Content/HTTP Handlers

30. Amazon Simple Storage Service (S3)
• Amazon S3 provides a simple web services interface that can be used to store
and retrieve any amount of data, at any time, from anywhere on the web
• It is designed to make web-scale computing easier for developers by allowing
storage of Web accessible static content
" Allows for easy static website hosting (No EC2 Servers required)
" Designed for 99.999999999% durability and 99.99% availability of
objects over a given year
• Gives developers access to the same highly scalable, reliable, secure, fast,
inexpensive infrastructure that Amazon uses to run its own global network of
web sites

31. S3 Bucket Setup – Static Web Hosting Enabled
• DNS abstracts the actual storage location from web browser

32. S3 DNS Setup

Static Content Copy to S3

33. Content Delivery Acceleration

34. CloudFront : Content Delivery Network (CDN)
• CloudFront can be used to deliver your entire website, including
dynamic, static as well as streaming content using a global network
of edge locations
• Requests for your content can be automatically routed to the
nearest edge location, so content is delivered with the best possible
performance
• It integrates with Amazon Web Services like EC2 & S3 to give
developers an easy way to distribute content to end users with
low latency, high data transfer speeds, and no commitments

35. CloudFront Distribution
" CF responds on its Domain Name and Alternative CNAMES

36. CloudFront Origin
" CF Origin points to the S3 Bucket containing static content

37. CloudFront DNS Setup

38. API Integration
Twilio Google Maps Amazon SQS

39. Google API C# Snippet
" Using the Google API to convert GPS to Street information

40. Twilio API C# Snippet
• Using the Twilio .Net SDK to send a Text Message and make a Phone Call

41. Amazon Simple Queue Service (SQS)
• Amazon Simple Queue Service (SQS) is a fast, reliable, scalable, fully managed queue service –
think MSMQ, RabbitMQ, JMS etc
• SQS makes it simple to decouple the components of a cloud application
• You can use SQS to transmit any volume of data, at any level of throughput, without losing
messages or requiring other services to be always available
• With SQS you can offload the administrative burden of operating and scaling a
highly available messaging cluster
• Used here to future proof your application: thumbnail images are pushed in the Summit2014Q
– This is to address the requirement of a “future application back-end-system”

42. SQS C# AWS SDK Snippet
• Create an SQS queue and send a Message into it…

43. Polling SQS in the Web Console
• Queues can be managed from the web console

44. Now lets see the app…

45. How could we iterate next ?
• Mobile SDKs for additional Mobile Platforms iOS, Android
• Geo Library for Amazon Dynamo DB for geospatial queries
• Amazon SQS, Amazon SNS push notifications, and more
• IAM to provide more fine-grained access control
• Or use restricted temporary AWS Credentials
• Web Social Sign In with Amazon, Google & Facebook
• Row level segregation of user data in DynamoDB

46. Key Takeaways & Next Steps
