Total Cost of Ownership

Purchasing cost

20-25%

Post purchase/Maintenance cost

75-80%

What can be done?

Cloud Computing is the solution

Defining Cloud Computing



Cloud metaphor for Internet – add computing



Many Cloud Computing definitions

differing opinions one thing in common – Services provided via the Internet A Definition:

Cloud computing encompasses any subscription-based or pay-per-use service that is offered in real time over the Internet

Page  10

Cloud Computing



Model for enabling convenient, on-demand network access to a shared pool of configurable computing resources like networks, server storage applications, and services that can be rapidly acquired, used and released with minimal management effort or service provider interaction.



Cloud Computing customers do not own the physical infrastructure rather they rent the usage from third party provider.



They consume resources as a service and pay only for resources that they use.



Sharing resources improves the speed of computing when the servers are unnecessarily left idle.

What does the Virtualized Desktop Infrastructure look like?

Centralized Virtual Desktops Servers in Data Centre

Private Cloud Internet

Clients Workstation Thin Client Laptop Office Home Hotel (Roaming)

Devices Virtually Limitless ... Your Desktop, Anywhere You Are Your Desktop on a PC Your Desktop on an AppleMac Your Desktop on a Thin Client Your Desktop on a SmartPhone

As you move between devices, your desktop follows you!

Service Models of Cloud computing 1. Software as a Service (Saas) 2. Platform as a Service (Paas) 3. Infrastructure as a Service (IaaS)

Page  16

Software as a Service (SaaS)



Complete application is offered to the customer, as a service on demand



Single instance of the service runs on the cloud and multiple end users are serviced



On the customers’ side, there is no need for upfront investment in servers or software licenses, thereby reducing costs

Page  17

Platform as a Service (PaaS)



A layer of software, or development environment is encapsulated & offered as a service, upon which other higher levels of service can be built



Customer has freedom to build his own applications which run on the provider’s infrastructure



PaaS providers offer a predefined combination of OS and application servers to meet manageability and scalability requirements of applications

Page  18

Infrastructure as a Service (IaaS)



Provides basic storage and computing capabilities as standardized services over the network



Servers, storage systems, networking equipment, data centre space etc. are pooled and made available to handle workloads



Customer free infrastructure to deploy own software on the

Cloud deployment models

Private Cloud: Cloud infrastructure deployed, maintained and operated for a specific organization.

Community Cloud: number of Cloud infrastructure shared among a organizations with similar interests and requirements.

Helps limit Capital expenditure as establishment costs are shared among the organizations.

.. contd.

Cloud deployment models

Public Cloud: Cloud infrastructure available to public on a commercial basis by a cloud service provider.

Enables a consumer to develop and deploy a service in the cloud with very little financial outlay compared to the capital Hybrid Cloud: Cloud infrastructure consists of a number of clouds of any type.

Clouds have ability through their interfaces to allow data and / or applications to be moved from one cloud to another.

Can be combination of private and public clouds that support the requirement to retain some data in an organization, and also the need to offer services in the cloud.

More secure Challenge

Theft •

VHW Benefit

Virtual Workstations centralized Roaming users and data loss Unauthorized access to sensitive data Users unsecurely connecting to data • • • Access centralized data Data encrypted Restrict users downloading to USB, CD and DVD drives from home, hotel and laptops • Physical access to data restricted as it resides in a secure data centre • Access to sensitive data restricted through enforcement of permissions • Complex password authentication Page  24

Benefits of Cloud Computing

Page  25

Management and Support Challenge VHW Benefit

Manage and support multiple • end user devices complex and time consuming Manage and support standard VD in data centre much simpler and more efficient Mix of Operating Systems: 2000, XP Pro, Vista … • Standardization on all VD Different software versions • Create one standard VD image with all applications preloaded e.g.: Office, Adobe Reader, QuickBooks, Simply Acct etc.

• Users more productive Time consuming to perform patch management and security updates • Centralized management and support of VD Long wait time to resolve user issues Page  26 • Self healing - most issues can be resolved by logging off\on VD – takes less than 5 minutes

Business Continuity and Disaster Recovery Challenge VHW Benefit

Back up failure • Test restores performed • Data backed up every 4hrs\ day \ week \ month \ year Data loss due to: • user error • • corruption hard drive failure • Quickly able to recover data therefore limiting downtime and lost productivity • Quick and cost effective Distaster strikes and business continuity • Data backed up and stored on multiple devices • Devices stored in multiple locations Page  28

Benefits of Cloud Computing

Hardware and Licensing Challenge

Purchasing hardware and licensing every 4 years – expensive Obsolesence Upgrade RAM and hard drives inefficient Space issue

VHW Benefit

• Never purchase hardware and licensing again • • • Lead time for hardware instant Never worry about upgading to the latest hardware\software version again Very quickly add more RAM and hard drive space on the fly • Frees up space on users desk Noise and heat Heavy laptop • Thin clients has significantly less noise and heat • Do not have to carry heavy laptop around – access anywhere, anytime Page  30

Cloud computing

How Green is it?

Green benefits of Cloud Computing Servers

   Virtualize therefore reduce # servers e.g. 5 to 10 virtual servers to 1 physical server Less space required Reduced power

Workstations

  Thin clients and hence reduced power – 8watts compared to 80watts Virtual workstations running on servers – 30 to 70 wks to 1 server

IT Support

  Workstations that are not used are switched off Maintenance performed real time

Environmental

  Lower carbon emissions – less power needed Recycle / reuse old equipment Page  34
