  • In 1999 Salesforce started delivering applications to users using a simple website. The applications were delivered to enterprises over the Internet, and this way the dream of computing sold as utility started being reality. Although the service was successful, some more time would pass until it would become widespread.Amazon was next on the bandwagon, launching Amazon Web Service in 2002. Then in 2006, Amazon launched its Elastic Compute cloud (EC2) as a commercial web service that allows small companies and individuals to rent computers on which to run their own computer applications.

  • History Virtualization Virtualization is “something which is not REAL, but displays the full qualities of the REAL”. In computing, virtualization is the creation of a virtual (rather than actual) version of something, such as a hardware platform, operating system (OS), storage device, or network resources. A software implementation of a machine that executes programs like a real machine.What is cloud computing ?

  • Virtualization Hardware virtualization In hardware virtualization, the host machine is the actual machine on which the virtualization takes place, and the guest machine is the virtual machine. The words host and guest are used to distinguish the software that runs on the actual machine from the software that runs on the virtual machine. The software or firmware that creates a virtual machine on the host hardware is called a hypervisor or Virtual Machine Manager.What is cloud computing ?

  • Cloud Architecture Advantage & Disadvantage Advantage • Lower computer costs: – You do not need a high-powered and high-priced computer to run cloud computings web- based applications. – Since applications run in the cloud, not on the desktop PC, your desktop PC does not need the processing power or hard disk space demanded by traditional desktop software. – When you are using web-based applications, your PC can be less expensive, with a smaller hard disk, less memory, more efficient processor... – In fact, your PC in this scenario does not even need a CD or DVD drive, as no software programs have to be loaded and no document files need to be saved.What is cloud computing ? History Virtualization Needs of cloud Computing Services on Cloud Computing Cloud Architecture Advantage & Disadvantage YASH GAJERA
  • Advantage & Disadvantage Advantage • Instant software updates: – Another advantage to cloud computing is that you are no longer faced with choosing between obsolete software and high upgrade costs. – When the application is web-based, updates happen automatically • available the next time you log into the cloud. – When you access a web-based application, you get the latest version • without needing to pay for or download an upgrade. • Improved document format compatibility. – You do not have to worry about the documents you create on your machine being compatible with other users applications or OSes – There are potentially no format incompatibilities when everyone is sharing documents and applications in the cloud.What is cloud computing ?

  • Advantage & Disadvantage Advantage • Universal document access: – That is not a problem with cloud computing, because you do not take your documents with you. – Instead, they stay in the cloud, and you can access them whenever you have a computer and an Internet connection – Documents are instantly available from wherever you are • Latest version availability: – When you edit a document at home, that edited version is what you see when you access the document at work. – The cloud always hosts the latest version of your documents – as long as you are connected, you are not in danger of having an outdated versionWhat is cloud computing ? History Virtualization Needs of cloud Computing Services on Cloud Computing Cloud Architecture Advantage & Disadvantage YASH GAJERA
  • Advantage & Disadvantage Advantage • Easier group collaboration: – Sharing documents leads directly to better collaboration. – Many users do this as it is an important advantages of cloud computing • multiple users can collaborate easily on documents and projects • Device independence. – You are no longer tethered to a single computer or network. – Changes to computers, applications and documents follow you through the cloud. – Move to a portable device, and your applications and documents are still available.What is cloud computing ? History Virtualization Needs of cloud Computing Services on Cloud Computing Cloud Architecture Advantage & Disadvantage YASH GAJERA
  • Advantage & Disadvantage Disadvantage • Requires a constant Internet connection: – Cloud computing is impossible if you cannot connect to the Internet. – Since you use the Internet to connect to both your applications and documents, if you do not have an Internet connection you cannot access anything, even your own documents. – A dead Internet connection means no work and in areas where Internet connections are few or inherently unreliable, this could be a deal-breaker. • Does not work well with low-speed connections: – Similarly, a low-speed Internet connection, such as that found with dial-up services, makes cloud computing painful at best and often impossible. – Web-based applications require a lot of bandwidth to download, as do large documents.What is cloud computing ? History Virtualization Needs of cloud Computing Services on Cloud Computing Cloud Architecture Advantage & Disadvantage YASH GAJERA
  • Advantage & Disadvantage Disadvantage • Features might be limited: – This situation is bound to change, but today many web-based applications simply are not as full-featured as their desktop-based applications. • For example, you can do a lot more with Microsoft PowerPoint than with Google Presentations web-based offering • Can be slow: – Even with a fast connection, web-based applications can sometimes be slower than accessing a similar software program on your desktop PC. – Everything about the program, from the interface to the current document, has to be sent back and forth from your computer to the computers in the cloud. – If the cloud servers happen to be backed up at that moment, or if the Internet is having a slow day, you would not get the instantaneous access you might expect from desktop applications.What is cloud computing ?
