Architecting for the Cloud: Best Practices
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

- 23. Best Practices Exploring BestPractices for Architecting Cloud Computing
- 24. • Cloud providesabstract resources • They become Powerful when combined • Launch on demand Understand the Constraints
- 25. • Remove SinglePoint 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 looselycoupled components • Create asynchronous components • Isolate web, app and database servers • Design components as Service Interfaces Decouple your components
- 27. Decouple your components ControllerA 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 A Queue B Queue C 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 Smallmeans 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 automateddeployment • 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 asa “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 dynamicdata 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 Security Practices
