What is the advantage of cloud computing?
What is the advantage for the company?

    Take iCloud. Syncing data to the cloud and then also to your computer. It just makes everything that much safer. Having multiple sets of data. In terms of storing personal files, it's nothing you can't pull off yourself either.

    One could write an eBook about the whole topic but in short "cloud" usually means online, offsite and administrated by someone else. One exception to this is a "private cloud" you setup yourself onsite - within your own administrative domain.

    For a company "cloud" mostly is a question of:
    - costs doing things yourself
    - security
    - availability

    The benefit for a company is that they usually don't have to worry about things like backups and fail-over since the cloud service usually does that for you. Another benefit in most cases is less administration of hardware and software. In short: You save money.

    The contra points are security and availability.

    Yes, a cloud provider usually guarantees 99percent uptime. But that only covers their end. If your router or modem is fried or the ISP does some maintenance you are offline which means no access to the cloud.

    Even if the cloud provider does both, fail-over and regular backups you are not guaranteed your data is safe. In a worst case scenario the provider might lose all data "live" and "backups" and in those cases their ToS or contract usually protects them from compensating YOUR loss. [Of course those providers also do offsite backups but it may take weeks until you get your data back].

    The final point is security: 256-bit encryption, high-security facility, secure servers, etc. are just words... Putting your data in the cloud means giving them out of your hands. From an administrative that means you are responsible for security which you cannot even control, influence or whatever.

    "Cloud computing" is not actually a single thing and I don't think that what is true for one application is necessarily true for another. For example, Dropbox (storage synchronisation and backup), Hotmail (email) and GoogleDocs (office package) are all different. That said, here are some advantages:
    + Transferring much of the computing resources (storage and processing) to the cloud reduces the need to have those resources locally. For example, if you use cloud backup you don't need to have local backup, if you use cloud-based email then you don't need email servers etc.
    + This in turn leads to much simpler software setup on your PCs, so less software to install, maintain, update and reinstall if anything breaks (that's a BIG advantage).
    + Closely related to the above points, any new versions of the software are rolled out as soon as they're ready and your company can make use of them immediately (assuming not further training is required), rather than the usual rigmarole associated with local deployment.
    + Some features are built into cloud infrastructure but are difficult to implement locally so they may not actually exist at your company at present. One example would be the collaborative features in GoogleDocs.

    and disadvantages:
    - Heavier use of your bandwidth (you're effectively trading some of your local hardware for bandwidth).
    - Performance and features on cloud services are different from local ones. Cloud Office applications have less features and are generally slower than their local counterparts, and some applications are totally unsuited to cloud applications at the moment (there's no convincing equivalent to InDesign or Adobe Premiere, for example).
    - You are much more heavily dependent on your connection being up, and on your cloud provider which are both single points of failure (that said, cloud providers try to make their systems as reliable as possible and build in redundancy, and you should do the same with regard to your internet connection).
    - You become beholden to a single supplier for your software, on a rental basis, much more that you were on Microsoft (who are not exactly a beacon of openness and interoperability themselves). Imagine what would happen if you were unhappy with your suppiler, say, Google, and wanted to move to ZohoOffice. How would you do it?
    - Currently the price of most cloud services is quite attractive, GoogleApps for business, for example costs $50/yr. What's to stop a provider from raising the price at some point in the future?

    Yes but the problem is it will become like one more apple. which does the monopoly in smartphones and wants whole revenue for it self(by copying others ideas) is my fear.

    In many cases, it is a question of cost. By taking advantage of the cloud, overall IT expenditures may be reduced with a lower cost of hardware, software, infrastructure and personnel. This tends to be the driving force for many companys to move to the cloud.

    There are also disadvantages that are often overlooked or intentionally left unstated by those offering cloud services. A loss of your internet connection will bring those hosted services to a halt. With locally maintained services your workers can still work. If you are concerned with privacy regulations regarding your data, you need to take care since you cannot be 100% sure of what country your data is even being stored in and the rules of that country may open up your data in ways that could endanger the company's legal standing.

    There are probably other factors to consider, but you should not only look at the advantages offered by anything, but the disadvantages as well in order to fully understand the impact of the proposed changes.
