The document discusses some of the challenges with moving to public cloud computing. It outlines key questions around security, scalability, and segregation. Specifically, it notes that public clouds can scale instantly on demand but lack strong security controls and segregation between customers. The document provides recommendations around endpoint security, secure communications, service level agreements, and capacity planning to help address customer concerns with moving to the public cloud.

2.  Provider Examples
 Security
 Scalability
 Segregation
 Questions

3. Cloud =
Commodity

4.  AWS, EC2, S3
 Based on Xen
 Elastic – scalable and flexible
 No liability Service Level Agreement (SLA)

5.  Scalable?
 Instant capacity on demand
 Withstood Anonymous attack
 Secure?
 Obscurity, so much data.
 New controls coming online all the time. Hundreds
available now
 Segregated?
 NO

6.  No virtualization
 Massively scalable
 SLA for business customers – liability?

7.  Secure?
 Two-factor authentication
 Scalable?
 Massive
 Segregated?
 NO

9. Your customers WILL ask

10.  Virtual machine and hypervisor specific security
 Patch!
 Have a dedicated management network
 Investigate security providers - Bromium
 Endpoint security
 Control endpoints
 Containers and encryption
 Citrix XenMobile MDM
 Secure communications
 VLANs!
 Limitation of 4096 networks – investigate double tagging
 Netscaler/Access Gateway endpoints

11.  Service Level Agreements
 standards compliance
 benchmarking
 shared liability
 transparency of systems
 Offer security expertise
 independent certifications – SAS70, ISO, PCI, etc.
 Encryption
 data at rest

12. TRUST

13. Capacity planning is key

14.  Have a modular model
 Monitor usage
 Capacity planning
 User demands are huge, plan for it
 Redundant providers

15. Enterprise customers will demand it.

16.  Where is data stored?
 Where do processes run?
 Decisions – help your customer make the right
ones
 Which apps are suited for the cloud?
