AWS Summit 2014 Brisbane - Breakout 5 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. Presenter: Clayton Brown, Solutions Architect, Amazon Web Services

8. Now how to build this….

9. 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 Container as a Service”

18. Web Application Session State

19. ASP.Net Session State Management 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
http://aws.typepad.com/aws/2012/09/managing-aspnet-session-state-with-
dynamodb.html

20. 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 request traffic
– 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

21. NuGet integration in Visual Studio .Net
" Pre-packaged NuGet AWS tools can be installed to provide DynamoDB Session State Support

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

23. Static Content

24. 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

25. 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

26. 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

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

28. DNS Setup for S3
Route 53
cdn.stanski.me
(A Record to IP)
Development Server on AWS
Development Route 53
cdn.stanski.me
(CNAME to)
cdn.stanski.me.s3-website-ap-
southeast-2.amazonaws.com
Production
" DNS changes the underlying content origin systems
Static Content Copy to S3

29. Content Delivery Acceleration

30. 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 are 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

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

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

33. DNS Setup for CloudFront
Route 53
cdn.stanski.me
(A Record to IP)
Development Server on
AWS

" DNS abstracts the actual storage location from the web browser
Route 53
cdn.stanski.me

CloudFront Name:

Production
S3 Origin: cdn.stanski.me.s3-
website-ap-
southeast-2.amazonaws.com
Static Content Copy to S3

34. API Integration
Twilio Google Maps Amazon SQS

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

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

37. Amazon Simple Queue Service
• 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
LunchAndLearnQ
– This is to address the requirement of a “future application back-end-system”

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

39. AWS Web Console
• Queues can be managed from the web console
