5 Types of Cloud Computing Deployment Models

Cloud Computing Deployment Models functions as a virtual computing environment with a deployment architecture that varies depending on the amount of data you want to store and who has access to the infrastructure.

on the context of cloud computing, we have access to a pool of shared computer resources (servers, storage, software, etc.) on the cloud. When you need additional resources, all you have to do is ask for them. The clouds make it simple to swiftly start up resources. Resources that are no longer required can be released. You can use this strategy to only pay for what you actually use. All maintenance is handled by your cloud provider.

5 Types of Cloud Computing Deployment Models

The ownership, scale, and accessibility of the cloud, as well as its nature, intended use, and cloud deployment process, all influence the sort of cloud environment. A cloud deployment model specifies the ownership and location of the servers you are using. It describes your cloud infrastructure’s design, what you may change, and whether you can use services or if you have to build everything from scratch. The forms of cloud deployment also influence the connectivity between your infrastructure and your clients. The several cloud computing deployment models are described here.

Public Cloud – Cloud computing deployment models

Using the public cloud, anyone can access systems and services. It’s possible that the public cloud is less secure because it’s open to all users. In a public cloud, cloud infrastructure services are made online accessible to large industry organizations or the general public. In this cloud model, the infrastructure is owned by the cloud service provider rather than the consumer.

Customers and users can readily access systems and services because of this type of cloud hosting. This type of cloud computing is a great illustration of cloud hosting, where service providers offer services to a range of clients. Under this structure, storage backup and retrieval services are offered without charge, on a subscription basis, or per user. For example, take a look at Google App Engine.

Advantages of the Public Cloud Model

  • Minimal Investment: Because it is a pay-per-use service, there is no substantial upfront fee, making it excellent for enterprises that require immediate access to resources.
  • No setup cost: The entire infrastructure is fully subsidized by the cloud service providers, thus there is no need to set up any hardware.
  • Infrastructure Management is not required: Using the public cloud does not necessitate infrastructure management.
  • No maintenance: The maintenance work is done by the service provider (not users).
  • Dynamic Scalability: To fulfill your company’s needs, on-demand resources are accessible.

Disadvantages of the Public Cloud Model

  • Less secure: Public cloud is less secure as resources are public so there is no guarantee of high-level security.
  • Low customization: It is accessed by many public so it can’t be customized according to personal requirements.

Private Cloud – Cloud computing deployment models

The public cloud deployment methodology stands in sharp contrast to the private cloud deployment paradigm. In this situation, there is only one user (client). Allowing others to utilize your hardware is not required. Private clouds and public clouds are different in how you handle all of the hardware. It also goes by the name “internal cloud” and refers to the ability to access systems and services that are located inside a particular company or boundary. Utilization of the cloud platform takes place in a highly secure environment that is hosted in the cloud, protected by strong firewalls, and controlled by an organization’s IT department. More independence and control over cloud resources are available with the private cloud.

Advantages of the Private Cloud Model

  • Better Control: You are the sole owner of the property. You acquire total control over user behavior, IT operations, and service integration.
  • Data Security and Privacy: It is appropriate for holding company data to which only authorized employees have access. Access and security can be increased by dividing up resources within the same infrastructure.
  • Supports Legacy Systems: This approach is designed to work with legacy systems that are unable to access the public cloud.
  • Customization: Unlike a public cloud deployment, a private cloud allows a company to tailor its solution to meet its specific needs.

Disadvantages of the Private Cloud Model

  • Less scalable: Private clouds are scaled within a certain range as there is less number of clients.
  • Costly: Private clouds are more costly as they provide personalized facilities.

Hybrid Cloud – Cloud computing deployment models

By putting a layer of proprietary software between the public and private sectors, hybrid cloud computing combines the finest aspects of each. You can host the app in a secure place and gain from the financial advantages provided by the public cloud by utilizing a hybrid solution. Organizations may combine two or more cloud deployment techniques, depending on their needs, to move data and applications between different clouds.

Advantages of the Hybrid Cloud Model

  • Flexibility and control: Businesses with more flexibility can design personalized solutions that meet their particular needs.
  • Cost: Because public clouds provide scalability, you’ll only be responsible for paying for the extra capacity if you require it.
  • Security: Because data is properly separated, the chances of data theft by attackers are considerably reduced.

Disadvantages of the Hybrid Cloud Model

  • Difficult to manage: Hybrid clouds are difficult to manage as it is a combination of both public and private cloud. So, it is complex.
  • Slow data transmission: Data transmission in the hybrid cloud takes place through the public cloud so latency occurs.

Community Cloud – Cloud computing deployment models

It makes systems and services accessible to a variety of businesses. It is a distributed system created by mixing the features of several clouds to satisfy the particular needs of a community, industry, or business. The infrastructure of the community may be shared by the body that has shared objectives or duties. It is typically operated by a third party or a union of a few different local organizations.

Advantages of the Community Cloud Model

  • Cost Effective: It is cost-effective because the cloud is shared by multiple organizations or communities.
  • Security: Community cloud provides better security.
  • Shared resources: It allows you to share resources, infrastructure, etc. with multiple organizations.
  • Collaboration and data sharing: It is suitable for both collaboration and data sharing.

Disadvantages of the Community Cloud Model

  • Limited Scalability: Community cloud is relatively less scalable as many organizations share the same resources according to their collaborative interests.
  • Rigid in customization: As the data and resources are shared among different organizations according to their mutual interests if an organization wants some changes according to their needs they cannot do so because it will have an impact on other organizations.

Multi-Cloud – Cloud computing deployment models

The aim behind this paradigm is to use multiple cloud providers at once, as its name suggests. It is comparable to the hybrid cloud deployment method, which mixes resources from both public and private clouds. Multi-cloud utilizes various public clouds as opposed to combining private and public clouds. Despite offering a wide range of methods to increase the dependability of their services, public cloud companies still experience errors. It is exceedingly unlikely that two distinct clouds will come into contact with an event at the same time. Therefore, multi-cloud implementation further enhances your services’ high availability.

Advantages of the Multi-Cloud Model

  • By utilizing many cloud providers, you may combine and match the finest elements of their offerings to meet the needs of your apps, workloads, and business.
  • Reduced Latency: To reduce latency and improve user experience, you can choose cloud regions and zones that are close to your clients.
  • High availability of service: It happens very infrequently that two different clouds might experience an occurrence at the same time. Therefore, the multi-cloud installation improves the high availability of your services.

Disadvantages of the Multi-Cloud Model

  • Complex: The combination of many clouds makes the system complex and bottlenecks may occur.
  • Security issue: Due to the complex structure, there may be loopholes to which a hacker can take advantage hence, makes the data insecure.
