Everyone Is Talking About It

What Is “The Cloud”?

Where Is My Server? • You just can’t hug a cloud server

WHAT IS VIRTUALIZATIONCloud Primer

11

Before Virtualization

• 1:1 relationship between servers / hardware

• Memory / disk space / CPU tied to single server

• Lots of servers….• Lots of waste…

12

After Virtualization

• Many:1 relationship between servers / hardware• Memory / disk space / CPU shared across sets of servers• Fewer and bigger servers to manage….• Resource optimization…

• Dell PowerEdge Blade Enclosure• 16 Hardware “blades”• Up to 8 CPU “cores” each

• Its possible to run 128 serversin several square feet of space…..

13

What Magic is this?

• How do we fool many servers in to using the same hardware?

• How do we assure they play nice and the resources are allocated appropriately?

• Introducing the magic of the “Hyper-Visor”

14

What is a Hyper-Visor• A thin layer of magic software paint• Fools the operating system (Windows, etc.) • Manages allocation of resources• Manages fault tolerance• Provides a management interface to create and manage virtual servers

Magic Paint ->

15

How did we get to Cloud from Virtualization?

• Traditional virtualization still required in house servers• People saw the value of having more small servers• We all began buying bigger hardware• But the number of virtual servers skyrocketed….• So we bought more hardware....

• A vicious cycle!• We have more hardware than ever before to manage

and its even more critical than it used to be.

16

The Cloud is Born

• Amazon had built their own Private massive virtualized environment

• They figured out how to build a massive hypervisor network that spanned all of their data centers

• It was a key business need for their growth to be able to scale quickly and efficiently on a massive scale

• Whoa, we could “rent” our computing power to other companies! $$$$$

• Amazon EC2 and S3 were born as metered use offerings to the general Public

PRIVATE CLOUDDifferent Types of Clouds

19

Private Clouds

• Pool of resources that are solely yours to allocate• Most like the “Family Plan” we all know

– No one outside your family can share that pool of minutes, but you don’t get to use more than your total pool of minutes.

• Best for: servers that have stable resource usage

• Can be expensive if not fully utilizing resources

20

Private Cloud Providers

• Infrastructure as a service (IaaS)

• Offer dedicated hardware• Sage Nonprofit partners

with Rackspace on Sage Nonprofit Online

21

PUBLIC CLOUDDifferent Types of Clouds

22

Public Clouds

• Shared resources and/or bandwidth• Like a phone plan where you share minutes with your

entire city, a “Neighborhood Plan”

• Best for: when you need to scale internet facing servers, like web servers

• Pay premium for flexibility and burst capacity

• Example: “The Oprah Effect”

23

Public Cloud Providers

• Infrastructure as a service(IaaS)

• Platform as a Service(PaaS)

• Shared hardware only• Saleslogix and Sage

One hosted on Amazon EC2

• Watch for new Sage offerings on Windows Azure

24

HYBRID CLOUDDifferent Types of Clouds

25

Hybrid Clouds

• Creating a link between both a Public and Private Cloud so they can work together

• If you could have a “Family Plan” and “Neighborhood Plan” on your phone and choose to which plan to charge the minutes– You could be more conservative with your dedicated minutes

and more generous with the shared ones.

• Best for: when you need to scale some services (web, fundraising) but not others (reporting, backend database)

• “Buy the base, rent the spike”
