Provides a basic overview of cloud.

1. IT Solution as a Service, On-demand
 Consumption Model (Consumer’s view)
 Delivery Model (IT Manager’s View)
 An Architecture (Architect’s view)
 Technology (Developer’s view)

The “Big Switch” by Nicolas Carr
“… IT shall be consumed as utility”

2. 2
• Distributed
• Commodity based (x86)
• Data consistency over speed
• No single point of failure
• Built-in redundancy &
coherency
• Extension of virtualization
• Standard internet protocol based
• Web services based, world of API’s
• Pre-built, common components
• Large scale databases (ex:mongo)
• More open-source, less proprietary
• Self-service
• Built to scale-”out”, not “up”
• Massively scalable
• Plug N’ Play
• Multi-tenancy
• On-demand
• Self-service
• Pay as you go/grow

3.  SaaS/Hosted software
◦ SalesForce, Office 365, etc
 Provision H/W infrastructure instantly
◦ Amazon cloud servers, Amazon storage
 Develop webapps on the fly
◦ Google App Engine, AppFog, CloudAnt, etc
 Cloud-storage
◦ DropBox, Backup to cloud (eg: carbonite, mozy), etc

4. • Self-service
• On-demand resources
• Agility: Quick to provision
• Commoditized
• Inherent scale-out
architecture
• Built-in redundancy,
coherency
• Private, on-premise or
public
• Agility: Quick-to-develop
• Built on top of IaaS
• Legacy apps, new
approach
• Private cloud deployments
with custom integration
with home grown
applications
• Typically enabled in public
cloud
• High dependency on S/W

5. SaaS, Storage & Big data!
◦ “SaaS” Solutions
 Salesforce, Office365, Netsuite, Taleo, etc
◦ “Storage” for exponentially growing data
◦ “Big Data” for Business Intelligence

6. New data, New needs  New solutions!
 Hardware to software misalignment
 Birth of virtualization
 Massive data growth
 Need for non-traversing file systems
 Compliance, retention, regulatory
 Business continuity (DR), Security, Inexpensive-long term
storage
 Changing business needs. Sense of “Now!”
 Web 2.0

8.  Public
◦ Shared, multi-tenant infrastructure
◦ Highly scalable
◦ Limited by security & compliance
 Private
◦ Deploy within your 4 walls. Or, buy & host on dedicated infrastructure
◦ Highly Secure & Compliant
 Hybrid
◦ Pick & choose public and private
◦ Bridge them as one unified IT solution
◦ Choice of most organizations today
◦ Implementation challenges in real-world today

10. • Govt IT spend will be
considerably lower over
next 5 years
• Cloud based IT and
services in Govt sector
will be inevitable and
mandated. Ex:
• CloudFirst
• FedRamp
• Legacy IT apps will
continue but cloud’izing
them will be key

11.  Aligning IT strategy & investment to industry trends
 Technology transformations at lightning speed. Stay with
it or ahead of it!
 Resource constraints. Do more with less challenges
 Vendor lock-ins limiting organization’s growth
 Paying too much for proprietary solutions as you grow
11

12.  Cloud is “IT solution-as-a-service”, 10,000 foot view
 Cloud Tiers: IaaS, PaaS, SaaS
 Key impact areas: SaaS, Storage & BigData
 Cloud is not a myth, buzz or “one-size, fits-all” model!
 Govt. spending on IT is predicted to slow down, be prepared
So…
Understand, Evaluate, Adapt & Adopt
a right cloud strategy & roadmap for your organization!
Thank you!
