DESCRIPTION
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.TRANSCRIPT

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.
Why Cloud Computing?
What is the need for Cloud Computing?W

s?
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.
Business Goals V/s IT SpendBusinesses have big ideas !oDrive SalesoIncrease RevenuesoCut Costs
But IT Infra (expansion) & Business Apps are expensive leading to heavy CAPEX on IT
This is a major problem for the CIOs
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
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

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