Introduction: Cloud computing is a location-independent computing, whereby shared servers provide resources, software, and data to computers and other devices on demand. The term "cloud" is used as a metaphor for the Internet, based on the cloud drawing used in the past to represent the telephone network. Cloud computing describes both a platform and a type of application. A cloud computing platform dynamically provisions, configures, reconfigures, and deprovisions servers as needed. Cloud applications are applications that are extended to be accessible through the Internet.
What is Cloud Computing ? Cloud computing is a technology that uses the internet and central remote servers to maintain data and applications. Cloud computing allows consumers and businesses to use applications without installation and access their personal files at any computer with internet access. This technology allows for much more efficient computing by centralizing storage, memory, processing and bandwidth.
Types of Cloud 1. Public Cloud 2. Community Cloud 3. Hybrid Cloud 4. Private Cloud
PUBLIC CLOUD Public Cloud is also known as External cloud Public Cloud describes cloud computing in the traditional main stream sense, whereby resources are dynamically provisioned on a fine-grained, self- service basis over the Internet
COMMUNITY CLOUD A community cloud may be established where several organizations have similar requirements and seek to share infrastructure . Examples of community cloud include Googles "Gov Cloud”.
HYBRID CLOUD The term "hybrid cloud" is probably the use of physical hardware and virtualized cloud server instances together to provide a single common service. The term “Hybrid Cloud” is also used to mean as either two separate clouds joined together (public, private, internal or external)
PRIVATE CLOUD Private cloud is also known as Internal cloud In Private Cloud users have to buy there own servers, build them and manage them.
KEY FEATURES Agility improves with users ability to rapidly and inexpensively re- provision technological infrastructure resources Cost is claimed to be greatly reduced and capital expenditure is converted to operational expenditure Device and location independence enable users to access systems using a web browser regardless of their location or what device they are using (e.g., PC, mobile). Multi-tenancy enables sharing of resources and costs across a large pool of users Maintenance of cloud computing applications is easier, since they dont have to be installed on each users computer.
ISSUES Privacy: The companies hosting the cloud services control, and thus, can monitor the communication and data stored between the user and the host company. Availability and performance : The companies hosting the cloud services control, and thus, can monitor the communication and data stored between the user and the host company.
