Presented at IOUG Collaborate 2016 in Las Vegas Date: 11/04/2016 For many years software architects have discovered and implemented several concepts and best practices to build highly scalable applications. In today's era of the cloud, these concepts are even more applicable and critical. The cloud solutions faces many challenges due to growing data, unpredictable traffic patterns and demand for faster response time. In this session we will discuss best practices to architect for the cloud, how it is different from traditional design and introduce some new concepts in cloud computing. visit www.baigzeeshan.com for more technical topics

20. Microservices Architecture

21. • Technology Independence
• Easier Development
• Failure doesn’t cascade
• Component based Scalability
• Optimized for Replaceability

23. Best Practices
Exploring Best Practices for Architecting Cloud
Computing

24. • Cloud provides abstract resources
• They become Powerful when combined
• Launch on demand
Understand the Constraints

25. • Remove Single Point of Failure
• Design for automated recovery
• Graceful Failure, Use Services not Servers
• Consistent backup & recovery strategy
• Don’t Fix, start a new Instance
• Avoid Stateful sessions
Design for Failure

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

27. Decouple your components
Controller A Controller B Controller C
Call a Method
in B from A
Call a Method
in C from B
Tightly coupled Approach
Controller A Controller B Controller C
Queue

Loosely coupled Approach

28. • 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

29. • Create Small means very Small Services
• Find Independent Components
• Separate Operations and Data
• Define Owner of Each Service
• Small Teams better Communication
• Avoid Long Deployment Cycles
Avoid the Monoliths

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

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

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

33. • 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

34. • Configure SSL
• Create Virtual Private Cloud (Amazon VPC)
• Secure your Instances and applications
• Encrypt Files before upload (if required)
• Protect Admin Credentials
• Use IDM permissions
