1 x10 questions - and answers - about cloud computing

2 But first - Who am I?

3 1. What is cloud computing? "Cloud compu+ng is a generic term used to describe the disrup+ve transforma+on in I.T. towards a service based economy driven by a set of economic, cultural and technological condi+ons..."

4 1. The illusion of infinite compu3ng resources.. 2. The elimina3on of an up- front commitment by Cloud users.. 3. The ability to pay for use as needed a) Signup for an AWS account Use your exis+ng Amazon.com account if you want b) Register a credit card Billed on the 1st of every month for usage prior c) hhp://aws.amazon.com/ec2

7 The Cloud's resources scale with user demands, and you only pay for what you use.

8 Cloud Security and Privacy, 2009, Tim Mather et al.

9 2. Why would anyone use it? Flexibility and scalability Time to market Cost savings Power savings Green savings... Increased agility in souware deployment

10 Pay by use instead of provisioning for peak Capacity Demand Capacity Demand Time Static data center Time Data center in the cloud Unused resources

11 Heavy penalty for under-provisioning Capacity Demand Capacity Demand Time (days) Lost revenue Time (days) Capacity Demand Time (days) Lost users

12 3. Why would anyone deliver it? Resource Cost in Medium DC Cost in Very Large DC Ratio 1000 servers 50,000 servers Network $95 / Mbps / month $13 / Mbps / month 7.1x Storage $2.20 / GB / month $0.40 / GB / month 5.7x Administra+on 140 servers/admin >1000 servers/admin 7.1x Price per KWH Where Possible Reasons Why 3.6 Idaho Hydroelectric power; not sent long distance 10.0 California Electricity transmihed long distance over the grid; limited transmission lines in Bay Area; no coal fired electricity allowed in California Hawaii Must ship fuel to generate electricity

13 4. What does it cost, and for whom?

16 Real life example, from Univ of Oklahoma Amazon EC2 offers a lower price alterna+ve, where you book an en+re server for up to 3 years, in which case the price is: $ year buy- in fee + $0.24 * 24 hours per day * 365 days per year * 3 years = $ per 3 years Whereas at OU it's: $0 buy- in fee + $0.35 * 24 hours per day * 365 days per year * 3 years = $ per 3 years So if you commit to using an Amazon EC2 server for 3 years all day every day - - it's prely much breakeven. Using it less than all day every day makes it more expensive per server hour, because of the $2800 buy- in fee.

17 Of course, it's not really breakeven at all, because Amazon EC2 lacks the following: (a) high performance interconnect (at OU, Infiniband); (b) high performance parallel filesystem (at OU, Panasas); (c) user services to help make people produc+ve (everyone on our team has experience working directly with users). If any of the following are true, then cloud compu3ng may be cheaper than centrally- managed resources: (i) your internal centrally- managed resources are expected to be idle a significant frac+on of the +me; (ii) your users don't need a high performance interconnect; (iii) your users don't need high performance parallel I/O; (iv) your users don't need high end user services. But if any of these is false, then you're probably beler off, in terms of cost, having centrally- managed local resources.

18 But comparisons should be done vs total cost of ownership - from start to finish. This is one of the tasks in the NEON project, mentioned later in this Q&A. And. NEON cost comparisons will include the value of flexible services and more.

19 5. Can I trust it?

20 5. Can I trust it? Cloud compu+ng is about gracefully losing control while maintaining accountability even if the opera+onal responsibility falls upon one or more third par+es.

21 !"#$%&"'($)*+$%,-.($-/$01-2+$3456)7-*$ There are many benefits that explain why to migrate to clouds Cost savings, power savings, green savings, increased agility in souware deployment Cloud security issues may drive and define how we adopt and deploy cloud compu+ng solu+ons

24 6. I want to try it on my own machines - how?

25 Hybrid Private / Internal Public / External The Cloud On Premises / Internal Off Premises / Third Party

26 7. Who is using this, who is delivering - today?

40 10....? This one is for you to ask us!

41 Wrapping up Cloud compu+ng is... a generic term used to describe the disrup+ve transforma+on in I.T. towards a service based economy driven by a set of economic, cultural and technological condi+ons... In prac+ce today you get... instantly, scalable, on- demand compute power, storage and bandwidth - pay only for what you use... and it is all here now, with many flavors and providers.

44 The rest of the day 10-10:30: Explain cloud components I : Storage, computing components named and explained. Explain command line tools vs AWS console vs Rightscale. 10: : Coffee break 10:45-12:00: Hands on I : Obtain AWS credentials, obtain command line tools for VM management and S3 management. Goal: launch a default Fedora 8 32 bit VM Lunch 13-13:30: Explain Cloud components II: RDS, SimpleDB, SQS application design 13:30-15: Hands on II : Start a VM (again), install anysoftware you like, then go through the process of bundling. Start from your bundle. If a user has time left: create an EBS and attach that to your VM. If a user has no software to install, use the s3-tools from this morning : User feedback, discussion, use cases that want to pilot?
