Presented at RMOUG 2016 in Denver on 02/11/2016 Building applications with high availability and scalability has always been a challenge to enterprises. In addition to that, you need infrastructure to support it and money to maintain it. The cloud offers a solution to all these challenges, but understanding and adopting of this emerging technology intimidates many. In this session, we will discuss how cloud can help you to achieve highly available and scalable applications and different design patterns, the benefits of applying those patterns, and how each piece can fit into the bigger picture of the cloud application architecture.

Benefits of Microservices Architecture

19. 19
• Microservices
– Fine grained SOA
– Many small services
– Business logic is inside
domain
– Faster messaging
mechanism
• SOA
– Promotes reusability
– Fewer advance components
– Business logic could be across
domains
– Depends on ESB and
Middleware

Best Practices
Exploring Best Practices for
Architecting Cloud Computing

21. 21
 Cloud provides abstract resources
 Powerful when combined
 Launch on demand more Instances
On demand provisioning
is
Better Scalability + Performance
Understand the Constraints

22. 22
 Design for automated recovery
 Don’t Fix, Start a new Instance
 Consistent backup & recovery strategy
 Resume on reboot use message queues
 Avoid Stateful session, use data-store
Design for Failure

23. 23
 More loosely coupled components
 Create asynchronous components
 Isolate web, app and database servers
 Design components as Service Interfaces
Decouple your components

24. 24
Decouple your components

25. 25
 Periodic Scaling (Daily, Weekly, Annually)
 Proactive Event based Scaling
• New Product launched?
• Marketing Campaign?
 Auto Scaling on Demand
• Based on Traffic
• Network I/O
Implement Elasticity

26. 26
 Make your Service Simple
 Hide Internal Implementation Detail
 Find Independent Components
 Separate Operations and Data
Avoid the Monoliths

27. 27
 Create automated deployment
 Clearly Define Instance role
 Create small recipes for install & configs
 Use Management tools like Chef, Puppet,
Docker
 Zero Human-induced deployments
Automate the Infrastructure

28. 28
 Acts as a “front door” to Services
 Access data, business logic
 Control Authorized Security
 Monitor API Activity
 Version management
Use API Gateway

29. 29
 Cloud makes parallelization effortless
 Elasticity + Parallelization = WIN
 Multi-Thread requests for fast response
 Traditional Architecture
• 1 Machine x 500 Jobs = 500 hours to Complete
 With Cloud Architecture
• 500 Instances x 500 Jobs = 1 hour to Process
Think Parallel

30. 30
 Keep dynamic data closer to computing
resources
 Keep static data closer to Users
 Use Import / Export Services for large data
transfer
 Use CDN (Content Delivery Network) to
cache static data such as images, videos,
audio, PDFs
Data Management

31. 31
 Configure SSL
 Create Virtual Private Cloud (Amazon VPC)
 Secure your Instances and applications
 Encrypt Files before upload (if required)
 Protect Admin Credentials
 Manage multiple users with IDM permissions
