Advantages & Disadvantage of Cloud Computing:-
Advantages of Cloud Computing:- There are many advantages over cloud computing, which are following:

  1. Lower IT infrastructure cost:- By using cloud computing, you need not to invest in larger numbers of more powerful servers, you also need not to require the IT staff for handling such powerful servers.
  2. Lower cost computer for users:-In cloud, you don't require a high-powered (and accordingly high-priced) computer to run cloud computing's web based applications because applications run on cloud not on desktop PC or laptop.
  3. Lower Software Cost:- It reduces the software cost because you don't need to purchase separate software packages for each computer in the organization.

    Cloud infrastructure eliminates the high software costs of the businesses. The numbers of software are already stored on the cloud servers. It removes the need for buying expensive software and paying for their licensing costs. The feature of time to time software upgrading retains your company’s time and money.
  4. Fewer maintenance cost:-The maintenance cost in cloud computing greatly reduces both hardware and software maintenance for organizations of all sizes.
  5. The cooked food:- The expense of adding new employees is not affected by the applications’ setup, installation and arrangement of a new device. Cloud applications are right at the desk of employees that are ready to let them perform all the work. The cloud devices are like cooked food.
  6. Increased computing Power:-The execution capacity of cloud servers are very high. It processes the application very fast.
  7. Unlimited storage capacity:- Cloud offers you a huge amount of storage capacity like 2000 GB or more than that if required.
  8. Lowers traditional servers’ cost:- Cloud for business removes the huge costs at the front for the servers of the enterprise. The extra costs associated with increasing memory, hard drive space and processing power are all abolished.
  9. Data Centralization:- Another key benefit of cloud services is the centralized data. The information for multiple projects and different branch offices are stored in one location that can be accessed from remote places.
  10. Sharing Capabilities:- We talked about documents accessibility, let’s hit sharing too. All your precious documents and files can be emailed, and shared whenever required. So, you can be present wherever you are not!
  11. Data Recovery:-Cloud computing providers enables automatic data backup on the cloud system. The recovery of data when a hard drive crash is either not possible or may cost a huge amount of dollars or wastage of valuable time.
  12. Cloud Security:- Cloud service vendor chooses only the highest secure data centers for your information. Moreover, for sensitive information in the cloud there are proper auditing, passwords, and encryptions.
  13. Instantly Test:-Various tools employed in cloud computing permits you to test a new product, application, feature, upgrade or load instantly. The infrastructure is quickly available with flexibility and scalability of distributed testing environment.


Disadvantages of Cloud Computing:- There are many disadvantages over cloud computing, which are following:

  1. Net Connection:-For cloud computing, an internet connection is a must to access your precious data.
  2. Low Bandwidth:- With a low bandwidth net, the benefits of Cloud computing cannot be utilized. Sometimes even a high bandwidth satellite connection can lead to poor quality performance due to high latency.
  3. Affected Quality:- The internet is used for various reasons such as listening to audios, watching videos online, downloading and uploading heavy files, printing from the cloud and the list goes on. The quality of Cloud computing connection can get affected when a lot of people utilize the net at the same time.
  4. Non-negotiable Agreements:- Some cloud computing vendors have non-negotiable contracts for the companies. It can be disadvantageous for a lot of businesses.
  5. Security Issues:- Of course, cloud computing keeps your data secure. But for maintaining complete security, an IT consulting firm’s assistance and advice is important. Else, the business can become vulnerable to hackers and threats.
  6. Lack of full support:- Cloud-based services do not always provide proper support to the customers. The vendors are not available on e-mail or phones and want the consumers to depend on FAQ and online community for support. Due to this, complete transparency is never offered.
  7. Incompatibility:- Sometimes, there are problems of software incompatibility. As some applications, tools, and software connect particularly to a personal computer.
  8. Lack of insight into your network:- It’s true cloud computing companies provide you access to data like CPU, RAM, and disk utilization. But just think once how minimal your insight becomes into your network. So, if it’s a bug in your code, a hardware problem or anything, without recognizing the issue it is impossible to fix it.
  9. Minimal flexibility:- The application and services run on a remote server. Due to this, enterprises using cloud computing have minimal control over the functions of the software as well as hardware. The applications can never be run locally due to the remote software.
  10. Cost Comparison:- Cloud software may look like an affordable option when compared to an in-house installation of software. But it is important to compare the features of the installed software and the cloud software. As some specific features in the cloud software can be missing that might be essential for your business. Sometimes you are charged extra for unrequired additional features.
  11. No Hard Drive:- As Steve Jobs, the late chairman of Apple had exclaimed “I don’t need a hard disk on my computer if I can get to the server faster… carrying around these non-connected computers is byzantine by comparison.” But some people who use programs cannot do without an attached hard drive.
