Types Of Cloud Computing

Types of cloud computing

Before talking about cloud computing advantage and disadvantage, let’s see the types of cloud computing.

Cloud computing is categorized into three types. So, you can choose your necessary type of cloud computing. The types of cloud computing are

  • Infrastructure as a service (IaaS)

Companies control their own computing, networking, and storing components through IaaS. Moreover, they do not have to manage them on-premises physically.

  • Platform as a service (PaaS)

PaaS provides developers with a framework that helps them build custom applications.

  • Software as a service (SaaS)

SaaS provides internet-enabled software to organizations via a third party.

Cloud Development Models

As our main discussion is about cloud computing advantage and disadvantage, we should take a look at cloud computing models. Cloud Development Models are mainly of three types: Private, Public, and Hybrid. A user can choose any of these according to his/her requirements.

Private Cloud

A private Cloud consists of an infrastructure that is owned by a single business. Also, a Private Cloud can be hosted either internally or externally.

The Private Cloud model is best suited for large organizations that focus on security, customizability, and computing power. But remember one thing. It’s way more expensive than the other two models.

Pros and cons of Private Cloud


  • Highest level of security
  • Greater control over the server
  • Highly customizable
  • No risk of sudden change that interrupts company operations


  • Requires IT expertise
  • Comparatively expensive
  • Hard to access data from remote locations

Public Cloud

This model provides services and infrastructure that are shared by all customers. It offers huge available space and easier scalability options. Organizations pay public cloud models on a pay-per-use basis. Thus it is a suitable solution for smaller businesses who want to save money.

Pros and cons of Private Cloud


  • Highly scalable
  • Cost-effective
  • Easy to manage
  • Not bound by geographical restrictions
  • Highly reliable


  • Less customization
  • Not the safest option for sensitive data
  • Less secured (according to sharing)
  • Lesser autonomy over servers

Hybrid Cloud

Hybrid cloud

A hybrid cloud is a good option for those businesses who seek the benefits of both private and public clouds. Combining these two models, the hybrid cloud provides a more tailored IT solution that meets specific business requirements.

Pros and cons of Private Cloud


  • Highly secure, flexible, and economic
  • Better security than Public Cloud
  • Cost-effective


  • Communication may be conflicted as it occurs between private and public clouds

The pros and cons of the above models might have relevance to cloud computing advantage and disadvantage. So, you should keep them in mind before choosing your desired variants of cloud computing.

Cloud Computing Architecture

Cloud computing architecture is an important topic and we should talk about it before jumping to cloud computing advantage and disadvantage.

As we all know cloud computing technology is used by both small and large organizations to

  • Store the information in the cloud
  • Access it from anywhere at anytime

All we need is an internet connection. We will discuss more on cloud computing architecture below.

Remember, cloud computing architecture is a combination of

  • Service-oriented architecture
  • Event-driven architecture

Cloud computing is mainly divided into two parts- Frontend and Backend

Let’s dive into the detailed description of cloud computing architecture.


It is used by the client. The frontend includes web servers such as

  • Chrome
  • Firefox
  • Internet explorer etc.

Client Infrastructure

Client infrastructure contains user interfaces and applications that are required to access the cloud computing platforms.


It is used by the service provider. The backend contains the resources as well as manages the resources and provides security mechanisms. It also includes huge storage, virtual applications, virtual machines, traffic control mechanisms, deployment models, etc.

  • Application

Application refers to a software or platform to which the client accesses. It provides the service in Backend as the client requires.

  • Service

It refers to the major three types of cloud-based services like SaaS, PaaS, and IaaS. It also manages the type of service that the user wants to access.

  • Cloud Runtime

Runtime cloud refers to the execution and runtime platform to the virtual machine.

  • Storage

It provides flexible and scalable storage services and management of stored data.

  • Infrastructure

It refers to the hardware and software components of the cloud. It includes servers, storage, network devices, virtualization software, etc.

  • Management

Cloud computing

I am talking about cloud Computing advantage and disadvantage. Except for the advantages, the disadvantages of cloud computing may concern its users. While you are considering moving your business into the cloud, you want to avoid the following common risks

  • data loss or theft
  • data leakage
  • account or service hijacking
  • insecure interfaces and APIs
  • denial of service attacks
  • technology vulnerabilities, especially in shared environments

Since you are interested in cloud computing advantage and disadvantage, read moreto know the disadvantages of cloud computing.

Risk Of Data Confidentiality

It is always a risk that other people can access the user data. So, data and cloud protection must be good to avoid the danger of data confidentiality. You should be aware of the fact that you will be sharing all your company’s sensitive information with a third-party cloud computing service provider. Hackers might access this information.

Depends On The Internet Connection

The Internet is the only medium to use cloud computing. Therefore, good internet connectivity is a must. You can’t access, store and gather any data from the cloud without having a good internet connection. In fact, your online business may not grow due to a lack of internet connection in your area.

The Level Of Security

Security threat is another drawback in cloud computing. Using a cloud computing system means we are fully entrusted with the security and confidentiality of data to companies that provide cloud computing services. To deliver management and outsourced monitoring of systems and security devices use Managed security service providers (MSSP).

Vulnerable In The Event Of An Attack

Cloud computing is an online system so there is a risk of attack which may occur suddenly. When an attack is occurred by hackers, the problems that occur are data security and data privacy.

Data Mobility

Suppose, a user terminates cloud computing services. So, what is the possibility of sharing data between cloud services, and how to retrieve data? There is local storage where the data can be used at any time.

Technical Problem

In case you face a problem using cloud computing, you have to solve it all by yourself. You may contact customer support which may not be available 24/7. Moreover, for some support, you have to count the extra costs.

As we know cloud computing has both advantages and disadvantages. Keeping the disadvantages of cloud computing aside, the number of users is increasing day by day.

Cloud Computing Issues

Aside from disadvantages, cloud computing has some issues too. Cloud computing advantage and disadvantage can be known if you have knowledge about cloud issues. The issues may include


The host company can access the user data with or without permission. The service provider may access the data at any point in time. Moreover, they could alter or delete information accidentally or deliberately.


Data and hosting hold many regulations. Users may have to adopt expensive deployment models to comply with regulations. Besides, providers avail this information on request in a non-disclosure agreement.


There is an involvement of third-party storage and security in cloud computing. So, security is a concern. The security issues can be classified into

  • Sensitive data access
  • Data segregation
  • Accountability
  • Malicious insiders
  • Privacy
  • Bug exploitation
  • Recovery
  • Management console security
  • Account control and
  • Multi-tenancy issues

The service providers may share user’s information with others. So, security presents a real threat.


This issue indicates reducing the effect of cloud computing on the environment. In the areas where climate favors natural cooling and renewable electricity is readily available, the countries with favorable conditions are trying to attract cloud computing data centers. The countries with no favorable conditions are unable to sustain high-end clouds.


If a customer purchases the hardware for its private use, it does not mean that he can not purchase the services of cloud computing for nefarious purposes. By using the purchased services launching attacks and cracking of passwords can happen.

Future Of Cloud Computing

We can not tell the future but we can predict it. The predictions about the future of cloud computing may affect cloud Computing advantage and disadvantage. By analyzing the present trends and usage here are the predictions about the future of cloud computing.

Increase Storage Capacity

Data is generated in a high volume and it is difficult to store it with security. Most companies need a place where they can store their data securely.

So, it is predicted that the future of cloud computing providers will provide more data centers at a lower price.

Enhanced Performance Of The Internet

It is also predicted that the internet quality will be increased. With the help of the IoT and cloud computing, we will be able to store data in the cloud for further analysis and provide enhanced performance.

Improvement In Cloud Services

As I told you before cloud computing includes IaaS, PaaS, and SaaS. We can achieve our desired goal through this. Cloud computing will be one of the leading technologies in the future. It is also predicted that PaaS and IaaS will increase gradually. Cloud computing is user-friendly for both and new organizations.


Security is the key factor in cloud computing. cloud computing is secured but not fully. In the future, preventing cyber-attacks and keeping our information safe will be the ultimate goal.


From small to large businesses, almost everyone uses cloud computing. We can save the setup cost of software that will lead to decreasing the use of hardware. A number of users use this because of its affordability. So, in the future, the cost of cloud computing will be more economic and easily available to all.

That’s all in today’s discussion. Hope you have known everything about cloud computing advantage and disadvantage.
