  1. 1. “CLOUD COMPUTING” Presented By Ms Deepavali P Patil Mauli Group of Institutions (MGI), College of Engineering and Technology, Shegaon.
  2. 2. CLOUD COMPUTING“Cloud Computing” is a new and promising paradigmdelivering IT services as computing utilities. As Clouds aredesigned to provide services to external users, providers need tobe compensated for sharing their resources and capabilities. Inthis Presentation, we have proposed architecture for market-oriented allocation of resources within Clouds. We have alsopresented a vision for the creation of global Cloud exchange fortrading services.
  3. 3. “Cloud computing” is an umbrella term used to refer toInternet based development and services.Cloud computing is the use of computing resources(hardware and software) that are delivered as a serviceover a network (Typically the Internet). The name comesfrom the use of a cloud-shaped symbol as an abstractionfor the complex infrastructure it contains in systemdiagrams. Cloud computing entrusts remote services witha users data, software and computation.
  4. 4. “Cloud Services” Infrastructure as a Service (IAAS) Platform as a Service (PAAS) Software as a Service (SAAS)
  5. 5. Infrastructure as a Service (IAAS) Infrastructure-as-a-Service(IAAS) like Amazon Web Services provides virtual servers with unique IP addresses and blocks of storage on demand. Customers benefit from an API from which they can control their servers. Because customers can pay for exactly the amount of service they use, like for electricity or water, this service is also called utility computing.
  6. 6. Platform-as-a-Service(PAAS) Platform-as-a-Service(PAAS) is a set of software and development tools hosted on the providers servers. Developers can create applications using the providers APIs. Google Apps is one of the most famous Platform- as-a-Service providers. Developers should take notice that there arent any interoperability standards (yet), so some providers may not allow you to take your application and put it on another platform.
  7. 7. Software-as-a-Service (SAAS): Software-as-a-Service (SAAS) is the broadest market. In this case the provider allows the customer only to use its applications. The software interacts with the user through a user interface. These applications can be anything from web based email, to applications like Twitter.
  8. 8. Types of Cloud Private Cloud Public Cloud
  9. 9. Private Cloud Private clouds describe offerings that deploy cloud computing on private network. it consists of application or virtual machines in a companys own set of hosts. they provide the benefits of utility computing, shared hardware costs the ability to recover from failure and the ability to scale up or down depending upon demand.
  10. 10. Public Cloud A Public cloud is one based on the standard cloud computing model, in which a service provider makes resources, such as applications and storage, available to the general public over the Internet. Public cloud services may be free or offered on a pay-per-usage model .
  11. 11. Hybrid Cloud Hybrid cloud is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together, offering the benefits of multiple deployment models. It can also be defined as multiple cloud systems that are connected in a way that allows programs and data to be a moved easily from one deployment system to another.
  12. 12. “Server Virtualization”
  13. 13. “Virtualization” is a method of running multiple independent virtualoperating systems on a single physical computer. Virtualization, incomputing, is the creation of a virtual (rather than actual) version ofsomething, such as a hardware platform, operating system, a storagedevice or network resources. A virtual organization is a collection ofpeople and resources that work in a coordinated way to achieve acommon goal. To use grid facilities, any user must subscribe to avirtual organization as a member. Each people or resource can be amember of more virtual organizations at the same time and eachvirtual organization can contain people or resources belonging todifferent administration domains.
  14. 14. “Server Virtualization” is the masking of server resources, includingthe number and identity of individual physical servers, processors, andoperating systems, from server users. The server administrator uses asoftware application to divide one physical server into multipleisolated virtual environments. The virtual environments are sometimescalled virtual private server. Virtual machines are based on thehost/guest paradigm. Each guest runs on a virtual imitation of thehardware layer. This approach allows the guest operating system torun without modifications. It also allows the administrator to createguests that use different operating systems.
  16. 16. Conclusion Today, the latest paradigm to emerge is that of “Cloud Computing” which promises reliable services delivered through next-generation data centers that are built on virtualized compute and storage technologies. Consumers will be able to access applications and data from a “Cloud” anywhere in the world on demand. The consumers are assured that the Cloud infrastructure is very robust and will always be available at any time.
