Basics: What is Cloud Computing?
Access Technology enabled services.
Allows Users to consume services.
Wikipedia- “Dynamically Scalable”.
A standardized IT Capability, via the Internet.

Basics: How does it work?
Application runs within the Cloud.
Desktop is connected via the Internet to a Server Farm.
Applications use large data centres and powerful servers that host Web applications and Web services.
Anyone can access a Cloud Application.

Service Models of Cloud
Software as a Service (SaaS) Providing software applications as service over internet
Infrastructure as a Service (IaaS) Providing infrastructure on demand.
Platform as a Service (PaaS) Combining SaaS and IaaS Delivering computing platform as a service

Software as a Service (SaaS)
Software distribution model by which the software and applications can be made available to customers over the internet.
Customer Pays as per the usage No need to purchase the license for the software / Applcation User can avail the suite of software anywhere in the world without
installing them. He just needs a normal computer with internet connection.
One major advantage of this is customer does not need to take care of upgrades, patches, security of their s/w. These activities are managed by cloud service provider.
Many vendors are available in market to provide SaaS. Office Live, Google Apps, Intacct, SalesForce, NetSuite are some of them.

Infrastructure as a Service (IaaS)
The customer does not need to worry about the hardware and systems and pays the nominal charges for using them.
In general, with IaaS you can choose the OS, no. of processors and processor power, memory and amount of storage required.
GoGrid, RackSpace, Amazon, FlexiScale are some of the vendors providing Infrastructure as a Service.

Platform as a Service (PaaS)
PaaS is something combination of SaaS and IaaS that means it provides a platform combining software and the infrastructure over internet.
This is primarily for those who want the complete package to work on
Windows Azure, Google App Engine, Force.com, AppScale, Engine Yard, RightScale are some of the cloud based technologies providing PaaS

Cloud Deployment Models
Public Cloud Third party provides cloud services Resources are dynamically provided over the internet
Private Cloud Within the boundaries(firewall) of the organization More secure as they are internal to organization
Community Cloud Several organizations having similar requirements and seeking to
share infrastructure establish a cloud Hybrid Cloud
Organization provides and manages some resources in-house and has others provided externally.

Importance: Why Cloud Computing?
![Page 14: Cloud Computing Final1](https://reader033.vdocuments.site/reader033/viewer/2022051411/541354958d7f7294698b458c/html5/thumbnails/14.jpg)
Cloud Computing Architecture
Divide them into 2 sections – Front end and Back end.
Front end and back end Connect to each other through a network (Internet).
Front end has the Client’s Computer and application required to access the cloud computing system for eg. Web browser.
Back end of the system consist of various computers, data servers and Data storage systems that forms the “Cloud” of computing services.
There is a central server which administers the systems. It follows a set of protocol and uses a special kind of software called Middleware and through this middleware software networked computers can communicate with each other and use the resources when needed.

How users connect to the cloud
Front-end interface seen by user
User selects a task or a service
User’s request gets passed to system Management
Calls the system’s appropriate provisioning services
Launch the appropriate web application
System’s monitoring and metering functions track the usage of cloud

Understanding Cloud Storage
Cloud storage is the subcategory of cloud computing
This is a form of networked data storage where data files are stored on multiple virtual servers.
The servers used for cloud storage are typically hosted by third party companies who operate large data centers.
When you subscribe to a cloud storage services, you lease storage capacity from cloud storage service.
You then have access to the contracted amount of storage space, which you access via the internet.
