Top 5 Disadvantages Of Cloud Computing

While cloud computing and storage is a great innovation in the field of computing, However, there are certain things that you need to be cautious about too. Some may say that there are no down sides to cloud computing, but users should not depend too heavily on these services. Although you may find all you need with a particular service, you have to consider the security and portability it offers and also make contingencies should the service be terminated abruptly.

Cloud Computing Disadvantages

Moreover, an online service is more prone to threats than your PC. Having said that, however, most would agree that with cloud computing, the good outweighs the bad.

The main disadvantages are Security and Privacy, Dependency (loss of control), Cost ,Decreased flexibility ,Knowledge  And Integration.

1.Security & Privacy

The biggest concerns about cloud computing are security and privacy. Users might not be comfortable handing over their data to a third party. This is an even greater concern when it comes to companies that wish to keep their sensitive information on cloud servers. While most service vendors would ensure that their servers are kept free from viral infection and malware, it Is still a concern considering the fact that a number of users from around the world are accessing the server. Privacy is another issue with cloud servers. Ensuring that a client’s data is not accessed by any unauthorized users is of great importance for any cloud service. To make their servers more secure, cloud service vendors have developed password protected accounts, security servers through which all data being transferred must pass and data encryption techniques. After all, the success of a cloud service depends on its reputation, and any sign of a security breach would result in a loss of clients and business.

2.Dependency (loss of control):

  • Quality problems with CSP(Cloud Service Providers).No influence on maintenance levels and fix frequency when using cloud services from a CSP.
  • No or little insight in CSP contingency procedures. Especially backup, restore and disaster recovery.
  • No easy migration to an other CSP.
  • Measurement of resource usage and end user activities lies in the hands of the CSP
  • Tied to the financial health of another Company.

3.Cost

Higher costs. While in the long run, cloud hosting is a lot cheaper than traditional technologies, the fact that it’s currently new and has to be researched and improved actually makes it more expensive. Data centers have to buy or develop the software that’ll run the cloud, rewire the machines and fix unforeseen problems (which are always there). This makes their initial cloud offers more expensive. Like in all other industries, the first customers pay a higher price and have to deal with more issues than those who switch later (although it would be very hard to create and improve new technologies without these initial adopters).

4.Decreased flexibility

This is only a temporary problem (as the others on this list), but current technologies are still in the testing stages, so they don’t really offer the flexibility they promise. Of course, that’ll change in the future, but some of the current users might have to deal with the facts that their cloud server is difficult or impossible to upgrade without losing some data, for example.

5.Knowledge  And Integration.

Knowledge:
More and deeper knowledge is required for implementing and managing SLA contracts with CSP’s ,Since all knowledge about the working of the cloud (e.g. hardware, software, virtualization, deployment) is concentrated at the CSP, it is hard to get grip on the CSP.
Integration:
Integration with equipment hosted in other data centers is difficult to achieve. Peripherals integration. (Bulk)Printers and local security IT equipment (e.g. access systems) is difficult to integrate. But also (personal) USB devices or smart phones or groupware and email systems are difficult to integrate.

  1. I was glad to observe that cloud techies r concerned about the inherent disadvantage(s) from the end-user/business point of view. Bio-metric n facial recognition type of controller-based log in to cloud server, rather than the traditional UID n passwd type of log-ins, will help in occluding the impersonators form the cloud data n experience. Thus more security n privacy will result.

  2. Thank you for the insight. I am excited about Cloud ERP, yet I like to take a balanced approach. Just as ERP was deemed the panacea for all business automation pains, Cloud ERP is positioned as a revolutionary approach to deploying an ERP solution. Cloud ERP provides a solution that is flexible, adaptable, scalable, efficient, and affordable. Customers can enjoy painless upgrades, rapid deployment, and easy customization along with availability “anywhere at anytime”! Practically speaking, Cloud ERP is just another deployment option available to customers. The activities required for an “on premise” ERP implementation are also required for Cloud ERP. The scope and responsibility for the implementation activities may be different but most assuredly they are still required. The following article will provide more insight on the impacts that Cloud ERP will have on the entire ERP lifecycle.

    nice i want history of the cloud computing that particularly who invented

    i feel cloud computing is one of best system to safeguard our data,but it must be made easier to operate or handle by the ordinary people…..

  5. good list of disadvantages.this article will help much for business organizations to take precautions before moving to cloud

  6. I was very misinformed prior to transferring from a VPS with our less then 1 Gig band site over to a cloud server. I should have done more research.
    If you like to see how fast our website is and with several errors please
    head over to crisiswhatcrisis.ca.

    I did learn that WordPress with certain popular plugins like Nextgen conflict.

    Do I hire a php guru or go back to VPS?

  7. For the past 25 years we have seen the MRPII and ERP disasters where people thought the technology was all about software. Whether you run it in-house or go to an external cloud provider the issues of internal process and cultural change will dominate the industry. The caution that needs to be observed relate to the down-side issues being written in many articles now with cloud concept computing. Stats show that up to 70% of ERP implementations to not realise the benefits touted in the sales pitch. A reason to tread warily.

  8. This is an excellent post. I read about the cloud computing online but never found out any post so true about the dis-ads as well. The threat from the network spammers is something that you cannot avoid when you are accessing the cloud computing.

  9. Good post, however as a gamer like me I find cloud a very bad idea in some cases. I’ll speak about gaming which is the subject that really interests me about cloud. First of all the thing about cloud gaming many gaming sites say “play from your browser” and “NO DOWNLOAD” yeah right like that’s true, I guess no one seen the huge amount of “temporary files” my sis has from Runescape (over 1gb for the matter). For those who played Drakensang Online, another good example of a cloud game, well it downloads the first 50-100mb right before you start the first area. Now My 2 examples were mmos and I’m fine with that.

    However the future may arrive (has already arrived for some games) to a point where a single player game saves your game in the cloud and that’s where problems arise should your connection drop. As already been mentioned in the article it’s also a privacy concern. I don’t wanna game and let know everyone when, how and how long I’ve been playing. Also another thing about cloud computing and that is server maintenance, as a gamer buying a game played in the cloud would not want frequent or long downtimes to be able to play the product I paid for.

    Bottomline, I don’t hate everything against cloud computing, However it has a very very long way to arrive to an acceptable point where I would satisfied as a customer.

    PS: My fav cloud computing technology atm is storage.

    Wouldn’t touch it with a barge pole! Despite the advantages I still want to be in control – not some third party.

  11. Nice points you have covered.Thanks for the informative post.

  12. We just had Hurricane Sandy on the East Coast. Crippling infrastructures, business and especially the power companies. No power, no data, right??! This is THE NUMBER ONE issue with cloud computing which was neglected on your list! Stick with an external hard drive! No need to worry about privacy and security!

  13. Hey Sarvanshu, great blog. I hope you don’t mind I found you through http://www.superb.net/blog/2013/03/04/top-9-disadvantages-of-cloud-computing/ where you were cited as a source. I added you on Google Plus too.
