Ever needed a powerful computer? Has your software always been up to date? There were times when you did not submit your project on time due to the weakness of the computer as a designer; As an accountant, you may not have access to the latest company information, and unfortunately, the file you have prepared at home needs to be modified. What do you think can be done?

What are the answers to these questions? Cloud computing as a solution to make the best and most efficient use of technology anywhere can answer all of the above questions. In the following, we will become more familiar with cloud computing.

What is Cloud Computing? The concept of cloud computing

When you hear words like cloud computing or cloud computing, you may be wondering what a cloud is. The cloud is where water vapor accumulates in the sky, and rain falls on all the points below it on the ground. Now, if we assume that the Internet is a cloud and that each person is a recipient of raindrops, you will get the answer to your question. In cloud computing, you no longer see the physical structure of your computer. Maybe you are working with a giant system with very high processing power, But others only see the small laptop in front of you. In cloud computing, the software is doing your commands elsewhere, and you can access them from anywhere in the world with the Internet. There are many advantages to cloud computing, and the entry of many technology-leading companies such as Google and Amazon in this area demonstrates its importance.

What is the history of cloud computing?

Cloud computing was first established in the 1950s due to the high cost of large computers and their large size; In such a way that several users had access to a central computer and used it at the same time.1970s, ​​using a separate central environment as a single processor became more important for multiple users.

 In the 1990s, various telecommunications companies introduced virtualized communications to users. 2002, Amazon unveiled a service called Amazon Web Services, which pioneered the technology. In 2006, along with Amazon, Google introduced its cloud service to the public, and many companies have entered the field.

What are the types of cloud computing models?

Cloud services model

Infrastructure as a Service (IaaS

Hardware systems such as servers and bandwidth used by large businesses and corporations can be replaced by cloud computing platform services. These services can provide a better experience to their users by reducing time and cost. Amazon Infrastructure Service is a well-known example of cloud infrastructure.

Platform as a Service: (Platform as a Service (PaaS

In the cloud computing service as a platform, you can easily access various and up-to-date software using the Google app engine, IBM smart cloud, and LongJump. Well-known companies such as Google and Amazon have introduced platforms such as stadia and cloud in gaming on cloud platforms.

Software as a Service: SaaS

Services are known as software as services are all or mainly run on a cloud database server. Famous examples of these services are Gmail, Netflix, Dropbox, iCloud, etc.

What are the benefits of cloud computing?

You can enjoy many benefits when using this technology, depending on your service. Below are some of the comprehensive benefits of this technology.

Cheap maintenance costs

Depending on the service you want, you can increase or decrease the amount of hardware power usage and pay the same amount. You no longer need to maintain a powerful computer or a huge server.

easy access

You can access all the facilities only with the Internet and smartphone or laptop without geographical restrictions. With the increase in global internet speed, especially the increase in speed and quality of the Iranian Internet, we will see more people welcoming these services globally and in Iran.

high power

You can easily access the most powerful system you need. Cloud storage is also helping you get the job done.

up to date

Another advantage of using cloud computing is that you always have access to the latest versions of all software.

Security and data recovery

Cloud computing services have shown tremendous results in data protection and security. This means that you no longer lose your information due to floods, power outages, or other events. These services protect your data well and back up your data from time to time.

Help preserve the environment.

Reducing the use of multiple hardware and reducing costs in this area can greatly help the environment. For example, management can reduce or increase the power of a company’s cloud servers as needed. But when using physical servers, usually only 30% of the resources are used, which is harmful to the environment on a large scale.

What are the disadvantages of cloud computing?

Despite all its advantages, cloud computing has its drawbacks.

Internet access

Although the Internet has become an integral part of human life in this age, There are places on the planet where internet access is either non-existent or poor.

Lack of a single standard

Although cloud computing has been around for years, there is still no single standard in terms and conditions. What is the value of cloud computing without a single standard? Of course, organizations such as Open cloud Consortium are working on standardizing these services and are constantly updating these standards to follow users’ needs in this field.

Protecting security and privacy

Another very important aspect of trusting in cloud computing is privacy. Both an individual’s privacy and a company’s confidential information are made available to these cloud services. The question is whether these services are highly secure or not. In this regard, many brands are increasing the security of their services.

High cost of immigration

Using cloud systems from the beginning is not a problem for a company, But this becomes difficult when it wants to enter its previous data into this new service. In the long run, the cost of migrating or using the servers may be more than saving the service. If a competitor uses the same platform as your company, you will lose one of the most important competitive categories.

Secondary processing of information

The personal information of many ordinary people incorporates data that can be processed along with other information. This provides a wealth of information to generate databases of user needs, targeted advertising, and more. It is important that the necessary measures to address these accessions are set out in formal contracts
