What is Cloud Computing?

• Style of computing where scalable and elastic IT-related capabilities are provided as a service to customers, using Internet technologies.

• It allows business to increase IT capacity on the fly and in real time without investing in new infrastructure.

• Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services).


Cloud Terminology & Concepts - Technologies


Virtualization


Cloud Characteristics

•Multi-tenant – the ability to process the needs of multiple users with shared resources in a dynamic and transparent fashion •Elastic – resources can expand and contract as needed •Scalable – resources can scale to tens of thousands of system •Metered/Rented – some manner of “pay for only what you use”‖ •Self-Provisioned – “self check-in” at least to some degree •Internet based – accessible using internet technology, usually over the public Internet •X as a Service – the details/concerns of implementation are abstracted for the customer •Dynamic and Autonomic – Monitoring and Adjusting to meet predefined service levels. •Secure – an overall decrease in risk due to greater security protocols and tools from the cloud provider for data in motion, data at rest and data in process.


Cloud Computing Journey


Do Organizations really want Cloud?


Cloud Computing Benefits

•Reduced Cost – Incremental, No Buy and Installation, Pay for Use •Increased Storage – Unlimited, No server upgrades •Highly Automated - Automatic Software Updates •Flexibility – Access data anywhere, anytime •More Mobility •Allows IT to Shift Focus – No Server/Software Updates •Quick & Easy – Gmail, hardware access, Multi-Tenancy •Green IT – Less Power


Cloud Computing Benefits


Challenges & Risk


Cloud Computing Mechanisms

•Virtual Server •Ready-Made Environment •Failover system •State Management Database •Pay for use Monitor


Virtual Server


Failover System


Pay for use Monitor

•Minimal or no upfront costs •Usage-based pricing, so that customer costs are based on actual usage •Elasticity, so that customers can dynamically consume more or less resources as and when they need it Benefits: •Awareness – Low Cost, Lesser Waste •Sharing of Resources •Pushes IT cost back to consumer


Ready Made Environment


Cloud Deployment Models – Public Cloud

• Off-site, third-party provider

• Offered to multiple customers

• Relegation of security management and day-to-day operations to third party vendor.

• Customer has low degree of control & oversight of the physical and logical security aspects of a private cloud.


Cloud Deployment Models – Private Cloud

• Customers buy, build, and manage and as such do not benefit from lower upfront capital costs and less hands-on management.

• Single Organizational tenant.

• Variety of Patterns (Dedicated, Community, Managed)

• Security management and day-to-day operation of hosts are relegated to internal IT or to a third party with contractual SLAs.

• Customer has high degree of control & oversight of the physical and logical security aspects of a private cloud.

• Easier for a customer to comply with established corporate security standards, policies, and regulatory compliance.
