Public cloud Applications delivered over the Internet in the software-as-a-service model. Computing resources such as storage or compute cycles delivered in the infrastructure-

as-a-service model Application development platform provided in a platform-as-a-service model

Private cloud, Also known as a Corporate Cloud uses cloud-like infrastructure and technology, such as virtualized servers in a scalable

architecture, to run applications behind the corporate firewall

Hybrid Cloud A hybrid model takes advantages of both public and private structures. Organization

may choose, for example, to run its e-mail system in the public cloud while keeping highly sensitive, customer-oriented applications behind the firewall


Introduction to Cloud computing

Public Cloud Vs. Private Cloud Vs. Hybrid Cloud


Why Microsoft Private Cloud

Why we opted for MS Private Cloud Windows Azure has already entered the public cloud market in a big way and has thousands (>10000) of

customers running on Windows Azure which gives prospective customers tremendous confidence in Microsoft’s Cloud expertise.

Microsoft will be running 85 to 90 percent of their apps in the cloud in the next five to ten years according to Steve Ballmer.

All new application development inside Microsoft are designed for the cloud according to Tony Scott CIO of Microsoft.

MS as its own biggest case study for the cloud. “moving 75,000 people to cloud-based Communications Server"

Microsoft has the best interoperability – Physical and Virtual, Cross Hypervisor. Microsoft provides comprehensive seamless management using Systems Center suite. Interoperability agreements with Novell, Citrix (Xen), and RedHat to support Linux on Hyper-V. Production Scalability:

http://technet.microsoft.com: 100% Hyper-V (~1 million hits a DAY) http://msdn.microsoft.com: 100% Hyper-V (~3 million hits a DAY) http://www.microsoft.com: ~50% Hyper-V and growing (>1 billion hits a month)



Wipro’s Journey towards Private Cloud Conceptualized way back in October 2009 by Wipro’s CTO’s office. (Microsoft technologies was

not ready then) Started working on a POC (Co-Innovation) along with Microsoft from April 2010. Working with the core DDC toolkit product team. Cross skilled team (Technology and Infrastructure) formed. First SI in the world to building a private cloud along with Microsoft on DDC Tool Kit. The Fabric and the portal built for Dynamic provisioning, Management and self healing is

Wipro’s IP.



Our Viewpoint Microsoft knows enterprise business requirements. Others may be "good enough" for the

average consumer, but it definitely isn't good enough for business. Microsoft is very well positioned to provide the best of both worlds.

Challenges / Learning'sChallenges Working with the Initial versions of the DDC toolkit / Beta Versions was quite challenging There wasn’t much of Documentation available on the DDC Toolkit WCF Services Limited support for the Toolkit No out of the box Reporting available initially. Configuring and running the sample Silverlight Portal from the Toolkit

Learning's Greater understanding of the DDC Toolkit Service offerings and improved comfort level in

using the same. SSRS Reporting provided with SC Products enabled us to create our own custom Reports based

on these samples. Provided custom features using Windows Power Shell scripting and WMI Programming. Built our own Star Rating algorithm for Hyper-V Hosts based on parameters like CPU, Memory,

Storage and Network Latency

Challenges / Learning'sChallenges Setting up the initial environment took lot of time and effort. The infra team had to work

closely with the Development team to understand the requirement needed to run the Sample Portals which were shipped with the DDC.

When we provisioned Virtual machines, they were not joining the Domain initially. Installing the SC VMM and SCOM Database with SQL Server 2008 R2 is not supported with

normal Installation. We faced some challenges in getting it working Faced issues related to DHCP and DNS when we moved to Production environment Setting up a VLAN is a Challenge.



Challenges / Learning'sLearning's Separate Active Directory, DNS and DHCP is required to setup private cloud using DDC toolkit. Pre configured template, ISO, Hardware and Software profile to be stored on the SCVMM

library. We have to restrict DHCP server not to issue any IP Addresses to Clients other than Hyper-V

Virtual Machines. Avoid creating multiple snapshots for Virtual machines. Get the valid IP Ranges from the network team and use them for provisioning the Virtual

Machines. Recommend usage of SQL server 2005 sp3 as it is compatible with SCVMM, SCOM and SCCM

database.
