Cloud Computing

1. Examples of websites

   • google docs, sky drive, icloud.

2. disadvantages

   • 1.Security breaches. Remember, I said that remote server security makes it harder, but not impossible, for hackers to reach your data. If there is a compromise of the server(s) where your data is stored, your personal information may be exposed to the world. There’s also a good chance that more than just your information may be affected—we're talking possibly millions of other users. 2.Outages. Have you ever been unable to access your email due to your provider being down? Now, imagine if you needed a document for an important business meeting or presentation and your storage provider’s site was down. Believe me it happens, and it happens at the most inconvenient times. 3.Storage limits. While your local hard drive may be able to hold 500GB or more of data, unfortunately a remote server may only allow you to freely store about 5GB. If you want more room, you’ll have to pay. Still, even with a paid account, it can’t begin to touch the amount of room you have locally. There also may be

3. Benifits

   • 1.Achieve economies of scale – increase volume output or productivity with fewer people. Your cost per unit, project or product plummets. 2.Reduce spending on technology infrastructure. Maintain easy access to your information with minimal upfront spending. Pay as you go (weekly, quarterly or yearly), based on demand. 3.Globalize your workforce on the cheap. People worldwide can access the cloud, provided they have an Internet connection. 4.Streamline processes. Get more work done in less time with less people. 5.Reduce capital costs. There’s no need to spend big money on hardware, software or licensing fees. 6.Improve accessibility. You have access anytime, anywhere, making your life so much easier! 7.Monitor projects more effectively. Stay within budget and ahead of completion cycle times. 8.Less personnel training is needed. It takes fewer people to do more work on a cloud, with a minimal learning curve on hardware and software issues. 9.Minimize licensing new software. Stret

4. Different types

   • 1.Web-based cloud services. These services let you exploit certain web service functionality, rather than using fully developed applications. For example, it might include an API for Google Maps, or for a service such as one involving payroll or credit card processing. 2.SaaS (Software as a Service). This is the idea of providing a given application to multiple tenants, typically using the browser. SaaS solutions are common in sales, HR, and ERP. 3.Platform as a Service. This is a variant of SaaS. You run your own applications but you do it on the cloud provider’s infrastructure. 4.Utility cloud services. These are virtual storage and server options that organizations can access on demand, even allowing the creation of a virtual data center. 5.Managed services. This is perhaps the oldest iteration of cloud solutions. In this scenario, a cloud provider utilizes an application rather than end-users. So, for example, this might include anti-spam services, or even application monitorin

6. Cloud storage

   • Cloud storage is a model of networked enterprise storage where data is stored in virtualized pools of storage which are generally hosted by third parties. Hosting companies operate large data centers, and people who require their data to be hosted buy or lease storage capacity from them.

7. What is it

   • the practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer.
