What is the Cloud?

5

Once Upon a Time…

…if you needed electricity, you had to produce it yourself.

6

Then a New Idea Came Out…

…generate A LOT of electricity centrally, and have everybody tap from it

7

What is Cloud Computing

Evolution of hosting

Source: Forrester Research, “Is Cloud Computing Ready For The Enterprise?”, March 2008

8

Why Cloud Computing

S+S: Outsource functions to external servicesThe Cloud is “Platform as a Service”

Host your own resources “in the cloud”Storage, Workflows, Services…

Expose your on-premise services “in the cloud” for others to consume

AdvantagesNo more IT headacheScaleReachPay as you use

9

Everything in the Cloud from now on?

“…larger companies…can be expected to pursue a hybrid approach for many years, supplying some hardware and software requirements themselves and purchasing others over the grid. One of the key challenges for corporate IT departments, in fact, lies in making the right decisions about what to hold on to and what to let go.”

Nicholas Carr“The Big Switch”

Microsoft Data Center in Chicago

Cost: $500 millionSize: 500,000 square foot facility (10 football fields)Container-based

FYI: Microsoft Averages the deployment of 10000 new servers

Claims Based Identity

Claims Based Identity ManagementIntroduction

TraditionallyWeb authentication uses “pure credentials”“Intranet” authentication relies on info from well known authoritiesDifferent authentication technologies are isolated silos

Claims based identity change all this byMerging credentials & subject information in a single artifactNegotiating authentication details on the fly via

Policies, open standards, trust relationship

When working with cloud resources we cannot afford any of these

The R-STS as Point ofTrust & Access Management

23

The R-STS Pattern is Ideal for Cloud Providers

Natural point of trust brokering with customers & partnersNatural point of authorization evaluation & enforcementResources are decouples by the original credentialsUse of StandardsPolicy based dynamic negotiations

Example: Exposing a Service via an R-STS in the Cloud

Identity.Biztalk.Net

Biztalk ServicesWhat is it

“BizTalk Labs provides early access to experimental connectivity and business process technologies”

ConnectivityNaming, firewall traversal, Eventing

Identity

Identity.Biztalk.Net

The IBN is a rules-driven, federated, claims based access control system

In practiceEvery BTS.Net account gets a dedicated R-STS instanceThe claim transformation logic is driven by user defined rulesCertain claims are evaluated directly into authorization decisionsClaims, rules, recognized issuers & crypto can be managed both via web portal and via API
