1. Be Smart, Use PwrSmart What Is The Cloud?

2. Where Did The Cloud Come From? We get the term “Cloud” from the early days of the internet where we drew a fluffy cloud to define a network of remote computers. 1 st Cloud was TCP/IP, Networking Abstraction 2 nd Cloud was WWW, Data Abstraction Our Cloud has evolved! The cloud Today - Abstracts infrastructure complexities of servers. Heterogeneous platforms, Applications, and Data.

3. The Cloud – It’s Constantly Evolving. Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources. (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort, or service provider interaction. This cloud model promotes availability and is composed of five essential characteristics, three service models, and four deployment models.

4. FIVE – Characteristics Of Cloud 1.On-demand self-service 2.Broad network access 3.Resource pooling - Location independence 4.Rapid elasticity 5.Measured service

5. Three – Cloud Service Models Cloud Software as a Service (SaaS) –Use provider’s applications over a network Cloud Platform as a Service (PaaS) –Deploy customer-created applications to a cloud Cloud Infrastructure as a Service (IaaS) –Rent processing, storage, network capacity, and other fundamental computing resources

6. Software as a Service - Definition Cloud Software as a Service (SaaS). The capability provided to the “end user” to use applications running on a cloud infrastructure and accessible from various client devices through a thin client interface such as a Web browser or application. The consumer does not manage or control the underlying cloud infrastructure, network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

7. Private cloud –enterprise owned or leased Community cloud –shared infrastructure for specific community Public cloud –Sold to the public, mega-scale infrastructure Hybrid cloud –composition of two or more clouds Four – Cloud Deployment Models
