Cloud architecture is one of the significant concepts which are gaining importance in the business world significantly. Therefore, it is very important to understand the concept of cloud architecture in order to be in the business world and function effectively and efficiently.

Cloud architecture is the result of advancement in technology and advanced technology has changed the way of doing business. Every firm is adopting advanced technology which provides a competitive edge to the organization. Thus, it has become necessary for the business to adopt advanced technology to achieve competitive advantage.

Cloud computing architecture is referred to various components in terms of software capabilities, databases, applications, and so on which are engineered in order to leverage the effectiveness as well as the power of the resources of cloud to solve of the problems of business. It is used to define the relationship between the cloud resources along with the components of them. The main aim of cloud computing architecture is to provide high bandwidth to the user.

It also allows users to have access to applications as well as data without any interruption. It also provides access to the on-demand agile network to move efficiently as well as quickly between the servers, clouds, as well as network security. There are several components of cloud computing architecture such as cloud resources, middleware, on-premise resources, and software components and services. But, cloud computing architecture can be broadly divided into two parts such as;

  • Front end
  • Back end

Both parts are connected through a network which is usually called the internet. The front end of the cloud computing architecture is considered as client part of the system. The front end consists of applications as well as interfaces which are needed to access the cloud computing platforms such as a web browser. On the other hand, the back end is referred to as the cloud itself. It includes all the resources which are required to provide cloud computing services. Now our Assignment Experts will tell you about the benefits of cloud computing.

Benefits of cloud computing architecture

Cloud computing architecture is widely being used in the businesses as it helps the businesses in several ways. There are several benefits of cloud computing architecture to the businesses. Some of the benefits to businesses have been discussed below.

Cost saving

It is considered that adopting cloud computing in business is highly costly. The initial cost of implementing the cloud-based server is high. But, there are several other factors which should be considered while thinking about the cost of implementing cloud-based server such as ROI. The organization can save time as well as money if it is on the cloud because it provides easy access to data of the organization.


Security is the main concern of any business because as technology is developing cyber threats are increasing. Therefore, there is a need to ensure the security of the data. Cloud computing architecture provides security to business data. Apart from this, the full-time job of a cloud host is to monitor the security carefully which is highly efficient than a conventional in-house system.


Cloud computing architecture provides business more flexibility than hosting on a local server. On a local server, a business cannot fulfill the need or demand of extra bandwidth but cloud-based services can fulfill the need for extra bandwidth instantly rather than updating the whole IT infrastructure.


Cloud computing architecture also helps businesses in gaining insight into the business problem. With the help of cloud computing architecture, the organization can also increase collaboration among various departments of the organization. It helps in controlling the quality. Disaster recovery is also one of the significant benefits of cloud computing.

Disadvantages of cloud computing architecture

Every technology has negative as well as the positive impact on the business. Therefore, it is important to analyze the positive as well as the negative impact of technology on the business so that the positive impact of the technology can be increased and the negative impact can be reduced or eliminated. Cloud computing architecture has also some negative impacts on business which have been discussed below;

Vulnerability to attacks

One of the biggest challenges of cloud computing architecture is the vulnerability to attacks. So, collecting and storing data in the cloud may have a serious issue of data theft because each data of the company is online. This is one of the potential risks of cloud computing although security measures are created to protect the data.

Dependency on network connectivity

Cloud computing architecture is totally dependent on the internet and thus it is very important to have regular internet services in order to function effectively and efficiently. The internet services should also be reliable and consistent along with high speed as well as bandwidth.


Downtime is also one of the biggest disadvantages of using cloud computing architecture. It has been observed that cloud service providers sometimes face technical outage due to several reasons such as low internet connectivity, loss of power, or due to maintenance. It will lead to downtime in the cloud services for time being.

Vendor lock-in

It is also possible that while migrating from one platform to another the organization may face challenges due to differences between the vendor platforms. Running as well as hosting applications of current cloud platform on other platforms can create support issues. Apart from support issues, there may also be the issues of extra expenses and configuration complexities. Now our experts from Assignment Help Canada will tell you abou the classification of cloud computing.

Classification of cloud computing

Based on the functions of the cloud, it is generally classified into the following;

  • Public cloud: public clouds can be defined as the clouds which services are hosted as well as provided by the particular cloud service provider. Therefore, the organization stores most of the data on the public cloud excluding confidential information. Some of the leading cloud services such as Google cloud, Azure, as well as AWS are the public cloud.
  • Private cloud: the cloud services which are developed as well as managed by the 3rd party host or the organization is called private clouds. Private clouds are used by organizations in order to manage private information. 
  • Hybrid cloud: the hybrid clouds are the clouds which are used to provide services of public clouds as well as private clouds. Hybrid cloud helps the organization to safeguard the important and critical information along with accruing the advantages of clouds at the same time. One of the significant features of cloud computing architecture is that the client may have the ability to scale in order to meet the organizational unique requirements.

Cloud service model

There are three main models of cloud service discussed below;

SaaS (Software as a service)

It is a cloud computing offering which provides access to the users to cloud-based software of the vendor. In this model, it is not necessary to install applications by the users on their local devices. Instead of installing application, the application resides on a remote cloud network which is accessed with the help of an API or web. The user or the client can store as well as analyze data through the application and collaborate on the assigned task.

Key features

  • The service provider or vendors provide applications and software to the users via a subscription model.
  • The users of SaaS do not need to install, manage, and upgrade the software because the providers manage this.
  • The failure of equipment does not lead to loss of data because data is secured in the cloud.
  • Depending on the service needs, the use of resources can be scaled.

IaaS (Infrastructure as a service)

It is a cloud computing offering in which the vendors of the service provider access to the resources of the computing to the users like servers, networking, as well as storage. The companies use their own applications as well as platforms within the infrastructure of a service provider.

Key feature

  • The user pays for Infrastructure as a service on demand instead of buying outright of hardware.
  • The infrastructure is scalable depending on the needs of storage and processing.
  • It helps in saving the cost of purchasing as well as maintaining the hardware.
  • There is not a single point of failure because data is stored on the cloud.
  • It also enables the virtualization of the administrative task which helps in freeing up time for other tasks.

PaaS (Platform as a service)

It is a cloud computing offering which provides cloud environment to the users in which applications can be developed, managed, as well as delivered. In this model, the users are able to use a suite of prebuilt tools along with the storage as well as other computing services in order to develop, customize, as well as test the own application.

Key features

  • It provides a platform along with some tools to develop, test, as well as host application in the same environment.
  • It also enables the companies to focus on the development without being too much concerned for the underlying infrastructure.
  • The service providers manage the security issues, server software, operating system, as well as backups.

Functions of cloud architecture

Cloud architecture has become of the most significant parts of the businesses because it helps the businesses to solve their problems or issues. It plays a significant role in securing important data of the business and hence the business can function effectively and efficiently in the market. The following are the functions of cloud computing architecture;

Storing important data of the business

The businesses use cloud computing architecture to store important data of the business. It does not only store the data but allows the organization to have access to the stored data at any point of time so that the organization can benefit out of it. It is very important to store important data because it can help in analyzing the data to identify the trends in the market.

Ensuring the security of the data

It is also very important to ensure the security of the data in order to work effectively and efficiently in the market. There is a threat to the market of being attacked by hackers. There are several hackers in the market who can damage the data and the organization can suffer a huge loss of data as well as critical information. So, cloud computing architecture ensures the security of the data.

Helps in solving the business problem

Cloud computing architecture helps in solving a business problem. Every organization faces several business-related issues every day. The organization should deal with the issues effectively and efficiently. Cloud computing architecture helps the organization to solve the problem effectively and efficiently. Security is one of the biggest issues of businesses. Cloud computing architecture ensures the confidentiality of the information. It also facilitates the organization to analyze the data to identify the trends as well as the level of demand in the market. Thus, it can be said that cloud architecture plays a very crucial role in businesses.

How to use cloud architecture effectively?

Cloud computing architecture is very effective in resolving business issues. But in order to make the use of cloud computing effectively, it is very important to develop effective strategies for cloud computing. The following are the strategies which can be used to use cloud computing architecture effectively.

The organization should enhance security with a single sign-on an organization password management solution. For any business, it is a good idea to use a single sign-on solution but it is highly effective for an organization which needs the use of several cloud computing accounts.

The organization should verify cloud security with the help of the third party. Verifying cloud security through the third party is effective for smaller organizations. But the organization which has large IT department should verify the security of cloud computing using own measures.

The organization should also implement end to end encryption. It will help in reducing the chances of a breach. It has been found that most of the cloud solutions encrypt the information at the time of transfer of data but do not store the data in the encrypted form. End to end encryption defines that the data should be encrypted in transit as well as at rest. Thus, the organization should look for such a solution which provides end to end encryption in order to ensure the highest level of security.

The organization should also ensure that the organization is performing in-house updates regularly. It is necessary to maintain a healthy information technology system. It should also be ensured that the organization is not running antiquated operating systems and updated as well as latest browser versions are used.

Evaluating cloud computing architecture

In order to ensure effectiveness as well as the efficiency of cloud computing architecture, it is very important to evaluate the performance of cloud computing architecture. There are five points which should be considered while evaluating cloud computing architecture.


The organization needs to prioritize its applications. The organization should identify the applications which are always available. It is necessary to consider high-quality technology for those applications which are always available. The organization should also rigorously test at the expense of building an internal solution.


The primary concern of every organization which is looking to cloud is the security. The organization should evaluate the measures which have been developed to ensure the security of the data. The main concerns of the organization regarding the security of the data are the risks allied with the environment of multi-users, loss of control of confidential as well as sensitive data, responding to several compatibilities as well as standards needed.


Most importantly, the organizations should know their obligations instead of knowing only what to expect from a service provider. It has been found that most of the service providers of the cloud do not support the administration.


It is necessary to know the requirement of the workflow which lies in the infrastructure. The organization should also identify the issues associated with it. It is also important to assess the cloud architecture that they have in order to ensure the effectiveness.


The organization should know where their data is. The organization should determine who will interact with the data. The area of compliance should be identified which the service provider compare as well as control with the regulations as well as standards which they aim to join.


Cloud architecture has gained a significant place in the business and hence almost every organization is trying to adopt and use cloud architecture. It significantly helps the business to solve the issues related to business. There are several advantages of cloud architecture such as cost saving, security, efficiency, mobility, as well as flexibility. However, there are some disadvantages of cloud architecture as well which significantly hamper the performance of the organization. Thus, the organization should identify the disadvantages of cloud computing architecture and develop effective strategies to deal improve the effectiveness of it. The organization should also evaluate the effectiveness of the cloud architecture on a regular basis in order to gain a favorable result. For more information you can also check Assignment Help.
