Cloud computing

  1. 1. PAPER PRESENTATION ON - Submitted by - Komal Mankar Chandan Kumar JhaDepartment of Computer Science / Information Technology J D College of Engineering, Katol Road, Nagpur
  2. 2. 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.
  3. 3. 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.
  4. 4. Representation of a cloud:
  5. 5. Types of Cloud 1. Public Cloud 2. Community Cloud 3. Hybrid Cloud 4. Private Cloud
  6. 6. 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
  7. 7. 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”.
  8. 8. 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)
  9. 9. 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.
  10. 10. 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.
  11. 11. 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.
