Types of Cloud Computing

In this tutorial, you are going to learn about Types of Cloud Computing.

Introduction

Cloud computing refers to the servers which are accessed all over the internet. In other words we can simply define it as storing, maintaining, securing the data and programs on the server that are hosted on the internet instead of being stored directly on the personal devices such as mobile phones and hard drives. Once the data is stored in the cloud we can easily open it around any corner of the world and once the data is backed up we can easily recover that file.

Types of Cloud Computing

There are four types of cloud:

  1. Public Cloud
  2. Private Cloud
  3. Hybrid Cloud
  4. Community Cloud

PUBLIC CLOUD

  • Public Cloud is a cloud model where the computing services are managed by third parties and support multiple customers.
  • Some of the organization which own, manage and operate public cloud are government organization, healthcare organization and many businesses.
  • This type of cloud needs high level of security and maintenance because it is shared among various users.

A public cloud is a type of cloud computing in which resources, such as servers, storage, and applications, are made available over the internet by a cloud provider. Public clouds are owned and operated by third-party companies, and customers can access these resources on a pay-as-you-go basis. Examples of public cloud providers include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).

One of the main advantages of public cloud computing is that it eliminates the need for businesses to invest in expensive hardware and software. Instead, customers can simply access the resources they need through the internet, which can be a cost-effective solution for small and medium-sized businesses that do not have the financial resources to invest in their own infrastructure.

In addition, public cloud providers typically invest heavily in security, and this allows customers to benefit from the provider's expertise and experience in securing data and applications. This can be especially useful for smaller companies that may not have the resources to invest in their own security measures.

Another advantage of public clouds is their scalability. Because the resources are provided by a third-party provider, customers can easily scale up or down their usage as needed, which can be particularly useful for businesses that experience fluctuations in demand. This can help customers to avoid over-provisioning resources and instead pay only for what they use.

Public clouds can also offer a number of additional benefits, such as automatic software updates, which can help customers stay up-to-date with the latest features and security patches. Furthermore, public clouds can offer a level of resilience that may not be possible with on-premises infrastructure, by providing multiple copies of data and applications across different locations. This can help to ensure that resources are always available and that data is not lost in the event of an outage.

However, there are also some potential downsides to public cloud computing. One potential concern is that customers may be subject to the provider's terms of service, which can include restrictions on the type of content or applications that can be hosted on their servers. Additionally, customers may need to rely on the provider's data centers, which can make it harder to meet regulatory compliance or local data sovereignty requirements.

In summary, public cloud computing can offer a cost-effective, scalable, and secure solution for businesses of all sizes, but it's important for customers to understand the trade-offs and evaluate whether public cloud computing is the right solution for their specific needs.

PRIVATE CLOUD

  • Private cloud is a cloud model where the computing services are managed by single user organization or private internet network.
  • It provides greater security control than public cloud because the resources are not shared which helps users to control the cloud environment.
  • Private cloud is more expensive than public cloud because purchase and maintenance has to be bared by the organization.

A private cloud is a type of cloud computing in which resources, such as servers, storage, and applications, are made available over a private network. Unlike public clouds, which are owned and operated by third-party companies and accessible over the internet, private clouds are owned and operated by the organizations that use them. This means that organizations have more control over their data and applications, and can customize their infrastructure to meet their specific needs.

One of the main advantages of a private cloud is that it offers a higher level of security and control over data and applications. Organizations can design and implement their own security measures and policies, and can ensure that their data is stored in compliance with industry regulations and standards. Additionally, organizations have more control over the location and accessibility of their data, which can be important for organizations that are subject to data sovereignty laws.

A private cloud also offers more customization options. Organizations can choose the specific hardware and software that they want to use, which can allow them to optimize their infrastructure for their specific use cases. This can be particularly useful for organizations that have specific compliance requirements or that want to use specialized tools and applications.

Another benefit of private cloud is that it can be more predictable in terms of cost. Since organizations own and operate the cloud, they can better estimate and control their spending, rather than relying on a public cloud provider's pricing model. This can be beneficial for organizations with fixed budgets, as it allows them to better plan and manage their IT expenses.

On the other hand, private cloud implementation can be quite expensive and complex. Building and maintaining a private cloud requires a significant investment in hardware, software, and personnel, which can be difficult for small and medium-sized businesses to afford. Additionally, private clouds can be more difficult to scale, which can make it harder for organizations to respond to changes in demand.

In summary, a private cloud can offer a higher level of security, control, and customization than a public cloud, which can be particularly beneficial for organizations that have specific regulatory or compliance requirements, or that want to control where and how their data is stored. However, the cost of building and maintaining a private cloud can be high, and it may not be the best option for organizations with limited resources or that experience fluctuations in demand.

HYBRID CLOUD

  • Hybrid Cloud is the combination of public and private cloud. It allow data and application to be shared between users.
  • It has unlimited storage and highly scalable so, it makes perfect balance between various business and multinational companies.
  • Even if the business find any fault during the functioning of hybrid cloud, the day to day operation will not be hampered.

Hybrid cloud is a type of cloud computing that combines both public and private cloud resources. It allows organizations to use a mix of on-premises, private cloud, and third-party, public cloud services with orchestration between them. This approach can provide the benefits of both public and private clouds while addressing some of the challenges of each.

One of the main advantages of a hybrid cloud is that it allows organizations to take advantage of the cost savings and scalability of public cloud resources while maintaining control and security of sensitive data and applications in a private cloud environment. For example, an organization may choose to run a public cloud for non-sensitive workloads such as web-facing application and store sensitive data in a private cloud.

Hybrid clouds can also enable more flexibility and optimization of resources. Organizations can choose to run certain workloads in a public cloud to take advantage of the scalability and cost savings, while running other workloads on-premises or in a private cloud to meet specific compliance or security requirements. Additionally, it can enable organizations to easily move workloads between different environments, depending on their current needs and requirements.

Another benefit of hybrid cloud is that it can provide better disaster recovery options. By having the ability to store data and run applications in both a public and private cloud environment, organizations can ensure that their data and applications are still accessible even in the event of an outage or other disruptive event.

On the other hand, implementing and managing a hybrid cloud environment can be complex and challenging. Organizations need to ensure that their data is properly secured and compliant while data and applications move between different environments. Additionally, they need to have the right tools and personnel to manage and maintain the environment, which can require a significant investment.

In summary, a hybrid cloud is a way to combine public and private cloud resources in a single, flexible environment, and this approach can offer the best of both worlds, providing the cost savings and scalability of public clouds with the control and security of private clouds. However, It also brings additional complexity to the IT environment, requiring an organization to properly manage and maintain it. Organizations need to evaluate their specific use cases, requirements, and resources to determine whether a hybrid cloud is the best fit for their needs.

COMMUNITY CLOUD

  • Community Cloud is a cloud model where computing services are managed to the limited set of organization such as between banks, colleges, health care institutes, etc.
  • It is more secure than the public cloud but less secure than the private cloud.
  • The community cloud is reliable and very helpful in analyzing and security of the business.

A community cloud is a type of cloud computing in which resources, such as servers, storage, and applications, are shared among a specific community of organizations that have common goals and requirements. This type of cloud is typically owned and operated by a third-party organization or a group of organizations that have a common need for the resources. It's a cost-effective solution for organization to share resources and infrastructure with other like-minded organizations.

One of the main advantages of a community cloud is that it allows organizations to share the cost and resources of building and maintaining a cloud environment, which can be particularly beneficial for small and medium-sized organizations that may not have the resources to invest in their own infrastructure. Additionally, community clouds can offer a higher level of security and compliance, as the community can establish specific policies and procedures for securing and managing the shared resources.

Another advantage of a community cloud is that it allows organizations to share expertise and best practices. By working together with other organizations that have similar needs, organizations can learn from one another and develop more efficient and effective ways of using the cloud resources. This can help organizations to improve their operations and better serve their customers.

Community clouds can also enable better collaboration and information sharing among community members. By sharing data and applications in a secure environment, organizations can improve communication and coordination, which can lead to more efficient and effective decision-making.

However, implementing and managing a community cloud can be complex and challenging. Organizations need to ensure that they are able to trust and work well with other members of the community, which can require a significant investment in communication and collaboration. Additionally, it can be harder to manage resources in a shared environment, which can lead to issues with availability and performance.

In summary, a community cloud is a type of cloud computing that is owned and operated by a group of organizations that have a common need for the resources, it's a cost-effective solution for organizations to share resources and infrastructure, also providing benefits in terms of security, compliance, collaboration and shared expertise. However, organizations need to be aware of the challenges of trust, collaboration and management that may arise when sharing resources with other organizations.
