  • 1. INTRODUCTION TO CLOUD COMPUTINGGGGG………..
  • 2. WHAT IS 'CLOUD COMPUTING'? "Cloud Computing" is a somewhat nebulous word to describe users "renting" or borrowing online software instead of actually purchasing and installing it on their own computers. It is the same business model as people using Gmail or Yahoo mail services, except that cloud computing goes much further. Cloud computing is where entire businesses and thousands of employees will run their computer tools as online rented products. All of the processing work and file saving will be done "in the cloud" of the Internet, and the users will plug into that cloud every day to do their computer work. 
  • 3. HOW CLOUD COMPUTING WORKS
  • 4.   AS WE KNOW CLOUD COMPUTING IS A GENERAL TERM FOR ANYTHING THAT INVOLVES DELIVERING HOSTED SERVICES OVER THE INTERNET.
  • 5. THESE SERVICES ARE BROADLY DIVIDED INTO THREE CATEGORIE :
    • 1. Software as a Service (SaaS)
    • 2. Platform as a Service (PaaS)
    • 3.  Infrastructure-as-a-Service   (IaaS)
  • 6. 1. SOFTWARE AS A SERVICE (SAAS)
    • Software as a Service describe the business model
    • of users logging into a centralized hub to access
    • their software products. Users open their files and
    • software only while online, using only their web
    • browser and passwords. It is similar to the idea of
    • mainframe terminals, but cloud computing involves
    • a much larger "cloud" (network) of processing
    • computers at the center.
  • 7. LETS UNDERSTAND SAAS
    • Ex 1: instead of selling you a copy of Microsoft Word for $300, a cloud computing model would "rent" word processing software to you through the Internet for perhaps 5 dollars a month. You would not install any special software, nor would you be confined to your home machine to use this rented online product. You simply use your modern web browser to login from any web-enabled computer, and you can access your word processing documents in the same way that you would access your Gmail.
    • Ex 2: your small car sales business would not spend thousands of dollars on a sales database. Instead, the company owners would "rent" access to a sophisticated online sales database, and all the car salesmen would access that information through their web-enabled computers or handhelds.
  • 8. 2. PLATFORM AS A SERVICE (PAAS)
    • generates all facilities required to support the complete cycle of construction and delivery of web-based applications wholly available in Internet without the need of downloading software or special installations by developers.
  • 9. 3.  INFRASTRUCTURE-AS-A-SERVICE   (IAAS)
    • provides informatics resources, such as servers, connections, storage and other necessary tools to construct an application design prepared to meet different needs of multiple organizations, making it quick, easy and economically viable.
  • 10. THE BENEFITS OF CLOUD COMPUTING:
    • The primary benefit of cloud computing is reduced cost for everyone involved. Software vendors do not have to spend thousands of hours supporting users over the phone... they would simply maintain and repair a single central copy of the product online. Conversely, users wouldn't have to shell out the large up-front costs of fully purchasing word processing, spreadsheet, or other end user products. Users would instead pay nominal rental fees to access the large central copy.
  • 11. THE DOWNSIDES OF CLOUD COMPUTING:
    • The risk of cloud computing is that the users must place a high level of trust into the online software vendors that they will not disrupt the service. In a way, the software vendor holds its customers "hostage" because all of their documentation and productivity is now in the vendor's hands. Security and protection of the file privacy becomes even more necessary, as the massive Internet is now part of the business network. When a 600-employee business switches to cloud computing, they must choose their software vendor carefully. There will be dramatically-reduced administration cost to use cloud computing software. But there will be an increase in the risks of service disruption, connectivity, and online security.
