Cloud Computing Overview
- 2. Agenda What is the cloud? How did we get here? Some sample Cloud applications State of the Cloud Cloud drives for your computer SaaS and PaaS Land mines and Gold mines
- 3. GOAL FOR THE DAY Not that you walk out with all the solutions (you should get some…), but that you walk out with a framework with which to judge future Cloud offerings and technologies.
- 4. KEY VOCABULARY • Hosting • Storage • Virtual Server • Private vs. Public • Software as a Service (SaaS) • Infrastructure as a Service (IaaS) • Platform as a Service (PaaS)
- 5. S O … WHAT IS THE CLOUD?
- 7. CENTRALIZED POWER ADVANTAGES Pay for power as you use it Share the cost of building the infrastructure Quick and easy to get power to your new building Someone else worries about hiring electrical engineers to keep turbines going Flexibility for when you grow or have temporary needs
- 8. DISADVANTAGES OF CENTRAL POWER When it’s hot in town, everyone wants more Outages can affect a lot of people Price doesn’t benefit from a competitive market
- 10. CENTRALIZED MONEY STORAGE Better protection that you can provide alone Marketplace provide competitive rates and services Insurance provided by the bank When they fail or get robbed, a lot of people lose money, but insurance can help

- 52. Why aren’t all of my movies available for Disc-to-Digital conversion? The list of movies available for Disc-to-Digital conversion is comprised of titles that have been legally cleared for digital distribution from studios participating in the UltraViolet program. We expect the number of titles available for Disc-to-Digital conversion to grow over time. Which studios are supporting UltraViolet™? The studios supporting UltraViolet include Paramount Home Media Distribution, Sony Pictures Home Entertainment, Twentieth Century Fox Home Entertainment, Universal Studios Home Entertainment and Warner Bros. Home Entertainment.
- 53. • 40% of companies in • 60% out or considering • 50% are worried about security flaws • 82% of cloud companies saved money • Biggest reason to move: multi-device access • 80% of business saw improvements in business • 93% saw improvements in IT • 63% of cloud users have multiple providers STATE OF THE CLOUD
- 55. “Unfortunately for IT, if this attitude lasts, the IT department will not” “The emergence of the cloud has accelerated the growing rift between IT departments and the senior executives” “Where companies have begun using cloud services, it appears that they will continue to do so” “Organizations that use the cloud can focus on their core competencies instead of waiting on IT and dealing with restrictions”
- 65. The Key Point • Traditional model of IT: purchase a capital investment and maintain and service over time until you have to replace it • Cloud model of IT: Spending from operational expense budget for a service when you need it
- 67. For your computer CLOUD DRIVES
- 110. CLOUD DRIVE NOTES Your data away from your computer (work, business, laptop, home) SugarSync will make multiple computer directories the same You’ll need to buy special software to backup your computer to the Cloud Photos typically get special treatment Skydrive shrinks them Skydrive and DropBox create galleries Sharing might include editing Skydrive and Google can edit in the browser Google Docs format is special Doesn’t count toward your storage quota Multiple people can edit at the same time Seeing your data on other devices SugarSync and DropBox support everything including Blackberry (DropBox: Linux, too!) Google works on iPhone and 3rd parties have stepped up for Android apps for SkyDrive Searching is not uniform across the platforms DropBox indexes filesnames only SkyDrive indexes the words inside Microsoft files (Word, Excel, PowerPoint, etc.) Google indexes everything! SugarSync doesn’t search!
- 113. SAAS AND PAAS And IaaS, too!
- 118. Elastic Cloud Compute (EC2) Amazon’s virtual server shop. Create and upgrade and expand server instances. Simple Storage Service (S3) Amazon’s cloud drive service. If you wanted to store videos or photos or files on your website (regardless of where it’s hosted), you can store them here. Elastic Block Storage (EBS) Amazon’s storage service for your virtual server that you house there. You put the operating system (Windows, Linux, etc.) here along with other files the server uses.
- 149. Benefits for IT OImmediate 24/7 ODelivery of applications on multiple device platforms OImmediate provisioning for better service OBetter backup and disaster recovery plans OImmediate multi-platform access OReduced staff
- 150. Tricky Stuff for IT O Integration between platforms O Credentialing in general and Single-sign-on in particular O Predicting and maintaining performance and bandwidth needs O Regulatory management and control O Does our software work there? Licensed properly? O From managing staff to managing vendors O Reporting and KPIs for Executives O Reduced staff
- 151. Benefits for the Business O Flexibility is better than forecasting O It’s good to be able to capture the revenue from a peak O Utility costing “plains” are preferred to “mountains and valleys” of capital costing O Agility in creation and delivery of new digital products and services O Probable cost reduction O Probable over-all technology improvements
- 152. Tricky Stuff for the Business O Change is hard – migrations and cut- overs and outages and training and new (important) partners can all present challenges O Multi-year contracts are sometimes hard to commit to O Difficult to properly weigh risk profiles and scenarios O Another batch of layers between the business and IT
- 153. A definition: Cloud computing is a model for enabling convenient, on- demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. National Institute of Standards and Technology
- 154. What it Boils Down to… Better Control • Your gear – your responsibility • You’re in charge of your own response to problems • You know the capabilities of your staff and can direct them • You just have to manage YOUR threats, not everyone’s Advanced Functionality • Quick to market • Quick to upgrade or downgrade as needed • Service-based metered pricing • 24/7 • Newer technology faster
- 156. Risk Mitigation • Cloud providers want predictable, multi- year, enterprise-wide agreements • Customers want PAYG add (and subtract) services as needed • Neither party can assume all of the risk o Vendors will go out of business o Customers will never put mission critical in the Cloud
- 157. Service Level Agreements • Is there an up-time guarantee and what are the penalties? Push for more than fee returns. o Consider Business Interruption Insurance • Understand where to go for support or to report a problem and what is the response time? • Do they have a DR plan in place? • Are your regulatory needs met (PCI, Cobit, etc.)? • Make sure you understand (or eliminate) “suspension of service” situations • Verify no data sharing with your private information.
- 158. STANDARD PATH TO THE CLOUD • experiment with unimportant service or software and with multiple providers • when something gets old, rent a cloud server • use for development and test, then deploy to owned gear • get comfortable and continue to migrate • experiment and migrate to PaaS/IaaS and SaaS • deploy new services on the cloud • consider reductions in technology support staff
- 159. “STARTUP” PATH TO THE CLOUD • Find SaaS providers for office applications • Develop and host web presence through partners • Hire technical people in year 5 to manage partners
- 160. Recommendations Nothing longer than a 2-3 year commitment if you have to commit You have to do your homework before you commit Integration with existing applications Network surveys to determine bandwidth needs Understand the SLA completely If you have an IT department, they need to be on-board (even excited) in order for this to work
- 161. Recommendations (con’t) Understand and practice your exit strategy (just another part of your BCP) If you have existing good relationships with hardware vendors, start with them
Editor's Notes
- #13: How did we get here in the cloud?
- #14: So 8 servers over there on the right (including the 1U server at the very top) and 30-40 servers on the left
- #15: Storage Area Network (SAN)
- #16: It was the safest place to house your equipment – but it’s still your equipment and you are still responsible for repairing, replacing and upgrading when needed.

- #20: http://www.datacenterknowledge.com/inside-microsofts-chicago-data-center/ One of the advantages of a container-based design is that the facility needs only to provide the hookups for electricity, chilled water and network connectivity. 2-4,000 servers can fit in a container.
- #21: 23-80 degrees allows for year-round “free cooling”

- #38: www.ringcentral.com $100 for 4 users per month; purchase a VoIP phone or use a headset and a soft phone on your computer. Or use your iPhone or Android phone as your office phone.
- #49: Private cloud is doing this JUST FOR YOU. The underlying physical hardware might be at your place and YOU provision it according to the needs of the business. Or it might be at a cloud provider or at a hosting company across town. It may be managed by you or a third party, but it exists just for you. Public clouds are build and managed for anyone who wants to play.

- #51: Kodak’s photo site was purchased by ShutterFly in May 2012
- #54: 45% of small businesses saved nothing 35% of businesses saved $20K or less From InformationWeek survey: Box.net claims more than 5 million users from 60,000 businesses (or dropbox or sugarsync or gmail or Amazon S3 from the IT department). So this is something to consider: your employees ARE using the cloud and what of yours are they putting out there? How will you get it back when they quit or die (or are sick for a while).

- #55: This section of the report is called “How to Make Cloud Soup” So the question to deal with is how to do data transfer between Cloud service providers.
- #56: What attitude? From the report: “When IT controls data center facilities, software and hardware — down to the brands of removable media in use — it’s likely to believe that control is essential to providing good service.” “Either IT is bad at communicating why it does what it does, or IT is fundamentally misaligned with the needs of the organization. Based on the State of Cloud Computing Survey results summarized here, I’m fairly confident it’s the latter”

- #64: One of the 3 largest suppliers of assessment tests for the public schools. They have MILLIONS of students in all 50 states taking CTB tests. They see the writing on the wall and have been working with schools to convert to the cloud. An example week from last year: over a two week period, 180,000 students took 5 tests a piece. So CTB had over 800,000 on-line tests to score. By 2015, CBT expects millions of children taking tests at the same time on-line. The cloud allows them to scale up and down depending upon the needs of the business.
- #65: Middle of September, 2012 Report from Nucleus Research
- #66: It’s a pain to do both, which is why many companies put new projects in the cloud or otherwise convert when faced with a new capital purchase.
- #75: Why would you UNCHECK any folders? Because you might have storage issues on laptops or older PCs and don’t want to use up the storage.
- #99: The Google Drive service

- #127: At the end of the first quarter of 2012, there were 905 billion objects in Amazon S3. We routinely handle 650,000 requests per second for those objects with occasional peaks substantially above that number. Here is the latest chart: From Amazon’s blog

- #136: Launched as a traditional server hosting company in 1998 The cloud part of the company uses datacenters in Chicago, Dallas, London and Hong Kong
- #137: One of the earliest cloud PaaS providers, heroku started as a Ruby on Rails web-app delivery solution in 2007. They specialize in apps now, particularly Facebook apps, but you can also create an entire web-based solution on their platform. There are over 400,000+ Internet applications using heroku

- #148: Megaupload boss Kim Dotcom in February as he is granted bail in a New Zealand court. DOJ shut him down in the middle of January. Kyle Godwin (NPR story on Friday the 13th in April) knocked his external HD off the coffee table right in the middle of a save and it trashed his backup. Then he remembered he put everything at Megaupload. The problem would be determining who was trying to get stolen movies and music back and who would be trying to get their legitimate data back – can you imagine being the conservator of that project and having to answer requests from people?
- #149: These guys are stuck with the bill to keep all the megaupload files while the trial goes forward. What do you get if there’s an outage? When Microsoft had its big outages last year with Office 365, which included downed email, customers got a paltry 33% refund on their monthly service fees.
- #152: I build two different server rooms at JCCC and managed a migration from one hosting center to another at Pioneer. The college will have considerable cost savings down the road when that “server room” space gets shut down and repurposed.
- #157: http://blogs.hbr.org/cs/2012/04/the_truth_about_cloud_economic.html?goback=%2Egde_56696_member_108494463 So your agreement have to compromise on both sides: go for flexibility and pay for great service
- #158: NetSuite says any month that they don’t meet their 99% uptime guarantee, they will reimburse the cost of that month’s services. Their security plan should equal or exceed yours Public Cloud providers typically do “Terms of Service” which is not an SLA
- #159: Remember – it’s happening now. People in the company are using cloud providers!
