Moving Cloud from Hype To Reality

  1. 1. Mark Brown Community Manager Windows AzureMicrosoft Corporation @markjbrown
  2. 2. • What is the cloud/characteristics• Differences between cloud and hosting• Why makes the cloud possible today?• Considerations for building cloud apps• IaaS Offerings• PaaS Offerings
  3. 3. What is the Cloud? Place to run apps, store data, and more Offers self-service provisioning of resources Provides granular, elastic allocation of resources Charged for the resources you use
  4. 4. Cloud Characteristics Provides high reliability Runs on commodity hardware Should allow for elasticity Should provide economies of scale Resources Cost
  5. 5. From Hosting to Cloud ComputingCapability Hosting Cloud Capacity Reserved On Demand Payment Per Month Per Hour Provisioning Managed Self-Service
  6. 6. We’ve had hosting forever.What has changed?
  7. 7. Bandwidth

  14. 14. Virtualization 2000 – Free BSD jails released 2001 – VMWare first server virtualization 2003  Xen: first open source x86 hypervisor  Microsoft releases Virtual PC for Windows 2006 –  VMWare Server offered for free  Microsoft: Virtual PC offered for free  Microsoft – Xen Hypervisor compatibility
  15. 15. REST
  16. 16. REST/Services Simplified managing resources Provisioning:  via a browser  inside your app Monitoring and management Makes self-service possible Final piece that ties it altogether
  17. 17. Before the Cloud. Could I… Create an iPhone app that could support exponential user growth? Do big data or scientific computing without investing in a massive data center? Create the next hot game on Facebook? YouTube Blog:  Today 72 hours of video are uploaded to the site every minute Could NetFlix or YouTube even exist?
  18. 18. Insane user growth Instagram Users450000004000000035000000300000002500000020000000 Users 1500000010000000 5000000 0 Oct Dec Feb Apr Jun Sept Nov Jan Mar May 2010 2010 2011 2011 2011 2011 2011 2012 2012 2012
  19. 19. 3 engineers + Cloud• 100+ instances running: – 3 nginx load balancers – 25 Django app servers – 12 hot Postgres, 12 replica – Redis, memcached, solr, workers, monitor, etc.• Not possible with traditional hosting or on- premise!!!

  21. 21. How Many Servers do I buy? Utilization120 This Many!!!10080604020 0 Jan Feb Mar Apr May June July Aug Sep Oct Nov Dec Jan
  22. 22. Some quick math Comparing just the servers themselves Assume: Test needs to run in 12 hr once a month Requires: 100 - 8 core, x64, 68 GB RAM If you bought servers yourself:  $5000 * 100 = $500,000 Cloud Spot Instances:  100 quad, XL High CPU, 12 hr/mo = $2200  $2200/month * 3 Years = $80K
  23. 23. Scale?
  24. 24. Design for the Cloud Build loosely coupled apps Service enabled Use Messaging & Queues Other Considerations:  Database replication  Database sharding  noSQL for high performance storage
  25. 25. Cat VideoDesign for the Cloud Load Balancers My Site  Serves videos  Injests Web Servers  Encodes Cache  Caches
  26. 26. Cat VideoDesign for the Cloud Load Balancers Loosely Coupled Service Enabled Messaging/Queues Web Servers Cache Scales independently No blocking Ingest Servers Encoding Servers
  27. 27. Database Replication Writes Master-Slave replication Writes on Master Reads on Slaves Master Heavy read, light write Not always consistent (lag) Slave Slave Slave Reads Reads Reads
  28. 28. Database Sharding Horizontal partitioning Name State Zipcode  Country/Continent Marco Ontario M4B 2E1  Postal Codes Cal Tennessee 37201  Date Range Keith Texas 73301 Mark Washington 98034  Consistent hashing
  29. 29. MarcoDatabase Sharding Shard Index:  Shard Id, Partitioned Data, Connection String  Consistent w/lazy writes or batch Lots of support:  Redis Shard Index  MongoDB  Win Azure DB Shards
  30. 30. noSQL Non-relational data store Super fast Good partitioning support Types:  Wide column  Hadoop, Casandra  Document store  mongoDB, CouchDB, ravenDB  Key/value  membase, redis, DynamoDB
  31. 31. IaaS – Infrastructure as a ServicePaaS – Platform as a ServiceSaaS – Software as a Service IaaS = Bring your own OS PaaS = Bring your own App SaaS = Bring your own Customers
  32. 32. SaaS You use this today Your mom might use it too Also very popular for mom
  33. 33. IaaS Virtualized OS Images Storage, Load Balancing, Databases, CDN, identity, caching, messagi ng + other value-add services
  34. 34. Iaas Strengths/Weaknesses Strengths:  Familiar technologies  Supports many scenarios  Limited code lock-in  Can control and configure environment Weaknesses:  Must control and configure environment  Requires administrative skills to use
  35. 35. Amazon Web Services Select an OS from massive library of images  Many flavors of Linux, Windows SQS: Queue hosted as a service on AWS  Unlimited queues & messages  64k message size, 14 day TTL Elastic Load Balancing:  Distributes traffic across your EC2 instances  Detects/removes unhealthy instances & reroutes  Works in a single AZ or across Availability Zones
  36. 36. Amazon Web Services Auto Scaling:  Monitor instance health  Provision/de-provision EC2 instances  Use with ELB to monitor latency to ensure adequate compute to handle demand Content Delivery Network:  Edge cache site and resources  Supports dynamic (per user) content  Pay for only what you use  Push everything, pay for what’s accessed.
  37. 37. Amazon Web Services RDS: MySQL, Oracle, MSSQL DynamoDB: noSQL, SSD, auto-scale, auto-replicated ElastiCache: Memcached compliant S3: Raw data storage, unlimited objects 1k-5TB Elastic BeanStalk (PaaS): VM-based  Java: Tomcat, AWS Toolkit for Eclipse, WAR, CLI  PHP: Apache, git  .NET: IIS, AWS Toolkit for VS or WebDeploy 2.0
