Cloud computing relies on sharing of resources to achieve coherence and economies of scale, similar to a utility (like the electricity grid) over a network.[1] At the foundation of cloud computing is the broader concept of converged infrastructure and shared services. Cloud computing, or in simpler shorthand just "the cloud", also focuses on maximizing the effectiveness of the shared resources. Cloud resources are usually not only shared by multiple users but are also dynamically reallocated per demand. This can work for allocating resources to users. For example, a cloud computer facility that serves European users during European business hours with a specific application (e.g., email) may reallocate the same resources to serve North American users during North America's business hours with a different application (e.g., a web server). This approach should maximize the use of computing power thus reducing environmental damage as well since less power, air conditioning, rackspace, etc. are required for a variety of functions. With cloud computing, multiple users can access a single server to retrieve and update their data without purchasing licenses for different applications.

3. What is Cloud Computing?
•‘Cloud Computing’ is a term used to refer to a
model of network computing where a program or
application runs on a connected server or servers
rather than on a local computing device such as a
PC, tablet or Smartphone.
•A “Cloud” is a computer network to Store,
Access and Share Data from Internet Connected
Devices.

4. Why Cloud Computing?

Services?

6. The need for Cloud
Services arose from Increased
Importance being given to IT
Services in a Business
Organization.
Which is a result of changes in
Business Strategy & Goals of the
Organization due to stiff competition
and their need to survive & grow.

7. Business Goals V/s IT Spend
Businesses have big ideas !
oDrive Sales
oIncrease Revenues
oCut Costs
But IT Infra (expansion) &
Business Apps are
expensive leading to heavy
CAPEX on IT
This is a major problem for
the CIOs

8. Issues in IT Infra expansion
• Space Issue
• Infra Issue
• Management Approval
• Finance Approval
• Vendor Identification & Rating
• Elaborate Procurement Process
• Delivery Time & Delay
• IT Human Resources
• Installation & Integration
• Networking & Telecom
• Testing & Training

9. Facts for Cloud Growth
1. Cut Costs on one side
2. Heavy CAPEX on IT on the other side
3. Improved Telecom Connectivity
4. Business Process Outsourcing

10. Cloud Model

11. The Optimal Solution
Migrate to Cloud Computing
Business Organization :
Outsource computing services to a CSP
Convert Capital expenditures to operating
expenditure in IT Services
Cloud Service Business Model :
Provide Computing Resources to
various customers on Sharing basis

Cloud

18. Benefits of Going to the “Cloud”
lCos can save a lot of money
lConvert Capital Capital Expenditures to Operating
Expenditure
lPay-per-use
lRobust Scalability
lReduce IT manpower
lCos can save lot of valuable time
lInstant availability
lCos can avoid mishaps

Routing & Managed Firewall

20. Do You Use Cloud?

21. Learn Cloud?

22. What is Open Stack?
Open Stack is a global collaboration of
developers and cloud computing
technologists producing the ubiquitous
open source cloud computing platform for
public and private clouds. The project aims
to deliver solutions for all types of clouds by
being simple to implement, massively
scalable, and feature rich.

23. Who uses Open Stack?
Corporations, service providers, VARS,
SMBs, researchers, and global data centers
looking to deploy large-scale cloud
deployments for private or public clouds
leveraging the support and resulting
technology of a global open source
community.

24. Virtualization
Virtualization is the creation of a virtual
(rather than actual) version of something,
such as an operating system, a server, a
storage device or network resources.

26. Benefits of Virtualization
• Hardware Abstraction
• Ease of Migration
• Encapsulation of Storage
• Ease of Growth
• Workload Consolidation
• Improved Remote Management
• Improved Monitoring and Troubleshooting

27. Red Hat Storage
• Red Hat Storage is a new distributed file
system (DFS) based on the Gluster file system.
• A distributed file system is a client/server-
based application that allows clients to access
and process data stored on the server as if it
were on their own computer. Red Hat Storage
acts as a scale-out network-attached storage
(NAS) and object storage software solution.

28. Benefits of Red Hat Storage
• Eliminates the need for proprietary storage
systems
• Storage can be configured in a variety of ways
• Redundancy is built-in
• Files are presented as one file system
structure independent of the underlying
physical storage location
• Offers scalable storage in the data center or
on-premise private cloud

30. Red Hat Certifications in Cloud
Computing
 Red Hat Certified Virtualization Administration(RH318)
 Red Hat OpenStack Administration (CL210)
 Red Hat Storage Server Administration (RH236)
 Red Hat Enterprise Clustering and Storage Management
(RH436)
 High Availability with Red Hat Enterprise Linux OpenStack
Platform (CL332)
 Red Hat CloudForms Hybrid Cloud Management (CL220)

31. A practical list of steps to take to
jump-start your cloud project.
lEducate the IT team.
lAdopt a “Cloud First” policy for any new projects.
lMove test and development to the public cloud.
lReview your IT maintenance schedule.
lConvene a cross-functional project planning team to identify
workloads to migrate.
lHire an expert to spearhead the project.
lConsider ongoing cloud support needs.
lBuild the migration and integration project plan.
