Before we jump to what are advantages and disadvantages of cloud computing. We need to know what cloud computing is first.
So what exactly does Cloud Computing’s understanding? I will explain completely with everything related to it. We no longer assume that virtual is just abstract and illusion.
We can accept virtual things. Also included with the term of cloud computing. This term refers to abstract internet technology but we use it on things that are real.
Even this technology has touched all fields, including storage media, industrial development, company policy direction and so on.
What is Cloud Computing?
I am sure that many of us are still lay with this one term, even though we may unconsciously involve this technology. The most obvious example is the use of Google Drive or Drop Box.
Cloud computing is the same as cloud computing or a technology that works by combining computer capabilities (computing) with internet-based services (Cloud).

So computing is a computer and cloud it’s internet. The internet is usually symbolized as cloud (cloud).
Wikipedia distributes cloud computing as a computer combined technology with internet-based development. The cloud is a symbol (metaphor) from the internet.
How Cloud Computing Works?
How do Cloud Computing work? To make it easier for you to understand it, I will explain using points.
- Cloud Computing works with a continuous online server on the internet network. On this server, all data and applications are stored. So whenever the user wants to access it, the server is ready to use.
- The user who wants to access the server, whether it is only to open, save, or run the program is required to log in first. New after logging in, users can access the server.
- Once the user accesses data or runs the application or opens a certain program, then the command inputted by the user will enter also to the server computer via the internet network. The results of the user action will be saved back on the server computer.
Well that’s how Cloud Computing works. Very simple actually, but requires very complex and complex technology.
An example of using Cloud Computing in this case for example the user who opens an email without the need to download and install the email application. But just enough to connect to the internet.
Types of Cloud Computing
Until now, there are several types of Cloud Computing services that we can use:
- Software as a Service (Saas) is a ready-to-use Cloud Computing service without the need for an application. For example hotmail, twitter, gmail, ymail, facebook, and others.
- Platform as a service (PaaS) is a Cloud Computing service that can be used to run applications from users. Examples of these services include Windows Azure, Google App Engine, Amazon Web Service, and so on.
- Infrastructure as a Service (IaaS) is a Cloud Computing service that focuses on providing IT infrastructure to users. For example hard disk, memory, network, server type, and so on.
Purpose of Cloud Computing
The basic question, why is there Cloud Computing? It turns out that if we explore more deeply, the existence of Cloud Computing was originally intended for a company.
Companies usually have to spend a lot of money just to make purchases on hardware and software. To outsmart it, Cloud Computing was created.
With this technology, companies can only buy one terminal but can use it all year round. From the beginning which was intended for companies, now the use of Cloud Computing has grown rapidly.
Many individuals use Cloud Computing for various purposes. Not only for storing data, but also for using online software.
Advantages of Cloud Computing
- The most highlighted advantage of Cloud Computing is that it can minimize costs.
- Cloud Computing works by utilizing the internet network, which means that Cloud Computing can be accessed anytime and anywhere. we can even access it even if we don’t use our own device.
- Cloud Computing has a flexible capacity. At the beginning you can indeed ask how much space capacity you need. But once the space you have is full, you can still apply for additional Cloud Computing space again.
Although it has many advantages, it does not mean that Cloud Computing is free from disadvantages. Just like two sides of a coin. There are advantages and there are disadvantages of cloud computing.
Disadvantages of Cloud Computing
- Security is still in doubt. Although many say that Cloud Computing has a good level of security, the facts prove otherwise.
- What happens on social media such as Facebook, Twitter, Instagram and others where user data can be easily disseminated by the server.
- Did not rule out damaged or at least down. We only rent cloud computing hosting. which is used for the server is also a computer. So it is possible if there could be a down or even damage.
Advantages of Cloud Computing for Companies
Not only that. The advantages of cloud computing in enterprise business are also very useful. That is why cloud computing technology is often used in a particular company.
If you want to try it, first take a look at the advantages and disadvantages of cloud computing for companies.
1. Costs Tend to be More Efficient
Using cloud computing is indeed very economical. Companies do not need to spend a large investment to create their own system.
This is because the way it works is in a virtual space of some special software and then connected to the network of each computer.
The company only pays for the use of the virtual space according to the desired capacity. So it does not charge any other fees.
If the use is felt to be more than that, you can ask for an increase or increase in the size of the room.
2. Ease in Business Management
It has been widely discussed from its function, indeed the advantage of using cloud computing in companies is that it makes business management easier.
This is of course because the system will assist in processing data and documents automatically, storing them in a virtual space.
Companies do not need to bother in managing all kinds of data and document management because they are already represent by the use of the system.
The existence of computerized assistance is indeed use to facilitate employee performance in order to produce better work.
3. Has Unlimited Storage Capacity
As briefly explained in the second point, companies are entitled to unlimited storage capacity according to their data and document needs.
Third parties or cloud computing service providers do have these advantages when providing services to clients. The capacity of the storage space that requires giant space can also still be serve because without that limit.
This is a plus point when a company decides to use it, because of course it will have a lot of data and documents regarding the work in question.
4. Has Back-up and Data Recovery Features
One of the advantages of cloud computing is back-up or recovery. The point is, of course, when a technical error occurs or for example the device is damaged, it will automatically be stored in a certain room.
After that, when there is a replacement.
The data and documents will come back again without being lacking. The advantages of this one system are indeed the company’s mainstay when it decides to choose it as a third party to store data and documents.
This recovery feature will automatically run when a new device is connect again and back up when there is a system failure.
Disadvantages of Cloud Computing for Companies
The name alone is a computerized system. It will certainly tend to have drawbacks because they are only machines depending on the network.
This makes it very weak when faced with the risk of data leaks or other, and here are some of the drawbacks.
1. Must be Connected with an Internet Connection
The advantage of using cloud computing is that it can be access anywhere but there must be an internet connection.
It turns out that this advantage becomes a boomerang which makes it a disadvantage, because when the user is in an area far from the signal, of course it hinders access.
2. There is a Security Threat for the Company
The first drawback that companies will think about when using cloud computing is the existence of security threats.
This is because the client will provide all important data and document information to third parties who may be new to service providers.
The existence of these third parties is of course very vulnerable to the risk of leaking company data and documents which are sometimes confidential.
A trusted service provider won’t do that but they are only human. They have a lot of clients so the chance of an accident is very high.
3. Raised Some Technical Issues
This technical issue has always been a source of deficiencies in the internet-connected systems of the company’s computers.
The existence of blackouts and maintenance can very well occur in the middle of the company doing its daily work. This will hinder the interests of work.
In addition, the name alone, the system, of course, will not be perfect because it is drive by a machine and users only need to use its convenience.
That’s the point that causes a technical issue, no different than writing in a program suddenly the computer shuts down but the data hasn’t been save.
Conclusion
Some of the advantages and disadvantages of cloud computing above can be take into consideration when using it in your company.
There is a solution to reduce the shortcomings, namely by double protection of important company data. However, the use of cloud computing in business management has proven to be effective and very secure.
This also depends on the policies of each company. The use of Cloud Computing has been very much.
Some examples that we usually encounter include Google Drive, Drop Box, as Cloud Computing that can be use to store data.
Then there is also Gmail, Yahoo Mail, Amazon as application services and so on.
