  5. 5. Defining Cloud Computing  Infrastructure as a Service (IaaS)  This is the most basic type of cloud service and offers servers (often as virtual machines), networking, and storage as services.  Examples of this include Amazon’s Web Services and Rackspace.  Platform as a Service (PaaS)  This cloud offering provides not only the hardware but a layer above, providing platforms to run custom applications usually specific to certain programming languages.  Examples of these include Microsoft’s Azure and Google’s App Engine.  Software as a Servie (SaaS)  This service is an offering of a finished product hosted in a multi-tenant manner (many customers on a single implementation).  Examples of this include Gmail, Sales Force, Service-Now, New Relic, and many more. 5“We wrote the book on scalability” www.akfpartners.com
  6. 6. Cloud Computing Trends In a 2012 survey by North Bridge Venture Partners with 785 respondents1:  3 drivers of cloud computing - scalability, cost, mobility  Only 3% consider it to be too risky — down from 11% last year.  Only 12% say the cloud platform is too immature — down from 26% a year ago.  50% of the survey respondents now say they have ―complete confidence‖ in the cloud  80% of respondents identify big data as the most likely sector to be disrupted by cloud computing  Eighty-four percent of all new software will be SaaS-based. Cloud is simply becoming the way we do things. 1 http://www.northbridge.com/2012-cloud-computing-survey 6“We wrote the book on scalability” www.akfpartners.com
  7. 7. SaaS  Gartner predicts that SaaS will hit $14.5 billion in 2012, a 17.9% growth from the previous year, with growth continuing through 2015 when it will be $22.1 billion.2  This growth is being fueled by several factors including new software design and delivery modules allowing for more instances of an application to run simultaneously, bandwidth costs continuing to drop, and customer frustration over the purchasing-implementation cycle.  According to CIOZone.com, a list of the top 60 fastest-growing public software companies in 2007 was dominated by companies switching from a proprietary license model to a subscription model. The demand for SaaS offerings is growing rapidly. 2 http://www.startable.com/2012/04/09/saas-growth-still-going-strong-according-to-gartner/ 7“We wrote the book on scalability” www.akfpartners.com
  8. 8. Concerns with Using SaaS: 1. What if the service is unavailable? "Everything Fails― 2. Where is your data backed up? 3. What is the cost? Including data migration 4. What level of access? 5. Does it comply with industry regulations? PCI, PA-DSS 8“We wrote the book on scalability” www.akfpartners.com
  9. 9. Concerns with Becoming SaaS  How do you move to SaaS without creating an RFP event for your customers?  ―The IT organization of the customer is held accountable for the solution regardless of on premise or SaaS‖ – Susan Rossnick, VP Engineering, Kronos  Availability  Scalability  People and Process 9“We wrote the book on scalability” www.akfpartners.com
  10. 10. Availability is a Feature Availability IS NOT a metric. • It is a FEATURE of your site. • It is the table stakes to join the SaaS game. 10“We wrote the book on scalability” www.akfpartners.com
  11. 11. Chasing a Rainbow Scalability is a Journey, not a Destination: • This is not a one time fee to play the game. • Failure to continually invest is a guarantee of failure. 11“We wrote the book on scalability” www.akfpartners.com
  12. 12. It Takes a Village Technology is Not Enough. You need: • The right people and the right org structure.. • The right processes. • Most importantly: The right MINDSET! 12“We wrote the book on scalability” www.akfpartners.com
  13. 13. PaaS  The demand for PaaS, at least among our clients, is not that great.  There are early indications that PaaS providers are starting to offer services that are moving them more into the IaaS market.  If you’re interested in PaaS your choices are very limited based on the technology stack that you are using. The real question is whether you should go directly to an IaaS provider or if you gain enough benefits from the PaaS provider to makeup for the additional cost. The demand for PaaS is NOT large. 13“We wrote the book on scalability” www.akfpartners.com
  14. 14. IaaS  The spend on IaaS cloud computing is expected to grow 48.7 percent in 2012 to $5.0 billion, up from $3.4 billion in 2011.3  Some of our clients have 100% of their services hosted on an IaaS provider while others are completely in a collocation facility or datacenter.  We are seeing more clients move towards a hybrid model. Own the base, rent the spike 3 http://articles.timesofindia.indiatimes.com/2012-08-07/infrastructure/33082032_1_ito-market-bryan-britz-saas 14“We wrote the book on scalability” www.akfpartners.com
  15. 15. Issues with IaaS  Security  Many IaaS providers are becoming PCI DSS, ISO 27001, and HIPAA compliant.  Using their service doesn’t provide you with the compliance - you need to be responsible for your own auditing.  Passing audits is not cut and dry but rather a negotiation with the auditors and therefore you need to be able to clearly articulate how you are following the standards or guidelines while utilizing cloud computing.  Cost  The cost of IaaS is decreasing  Most companies still find that if they run the servers (virtual machines) 24 hrs / day the break even is around 18 months. 15“We wrote the book on scalability” www.akfpartners.com
  16. 16. Issues with IaaS Cont’d  Inconsistent I/O  There is a huge amount of variability with some IaaS storage.  Some of our clients run Bonnie to test I/O prior to using the instance and then periodically to ensure it hasn’t dropped drastically.  You need to make sure your application can handle this variability or create work-around to handle this issue.  High failure rate  The virtual machines of most IaaS seem to be less reliable than bare metal.  Netflix who moved to 100% IaaS came up with Chaos Monkey and Simian Army to address this issue of less reliability. 16“We wrote the book on scalability” www.akfpartners.com
  17. 17. Case Study Overview  Client X is changing the way information is navigated and organized based on how people interact and relate to each other.  10B Monthly Page Views  400M Unique Visitors  916K Active Domains  Tracking 170M Users  1TB of Raw Log Data Each Day  100% hosted on Amazon’s EC2 17“We wrote the book on scalability” www.akfpartners.com
