Cloud Deployment Models: Definitions and Types

axle-networks-cloud-deployment-models

Cloud deployment models refer to the various ways in which cloud computing services can be provided to users. The primary cloud deployment models are public clouds, private clouds, hybrid clouds, and community clouds. Each model has distinct characteristics and benefits that cater to the diverse needs and requirements of organisations and individuals.

Let’s keep reading to learn more about the definitions and types of cloud deployment models.

What are Cloud Deployment Models?

Cloud deployment models are specific configurations of a cloud computing system that outline how cloud services are hosted, delivered, and accessed. These models define the type of cloud environment that an organisation uses and have an impact on security, control, and scalability.

Types of Cloud Deployment Models

Generally, there are 4 types of cloud deployment models: public, private, hybrid, and community clouds. According to Geeksforgeeks, ownership, scale, and access, as well as the nature and purpose of the cloud, are some of the characteristics that distinguish each type of cloud deployment model.

Public clouds are hosted by third-party providers and made available to multiple users via the internet. Private clouds are dedicated to a single organisation and provide greater control over security and customisation. Hybrid clouds combine elements of both public and private clouds, providing greater flexibility in workload management. Community clouds are shared by multiple organisations with similar interests or needs, creating a collaborative platform for data sharing and resource pooling.

Each deployment model has its own advantages and considerations that businesses should carefully evaluate before making a decision.

Let us now look at how each cloud deployment model works and what benefits it provides.

1. Public Cloud Deployment

Public cloud deployment involves hosting services and infrastructure off-site with a cloud service provider. It offers scalability, cost-efficiency, and accessibility, making it ideal for startups, small businesses, and organisations with fluctuating workloads. Examples of public cloud providers include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform.

Here are some advantages of the public cloud model:

  • Very Little Investment: It is a great option for businesses that need quick access to resources because it is a pay-per-use service with no significant upfront costs.
  • Zero setup costs: There is no need to set up any hardware because the cloud service providers fully subsidise the entire infrastructure.
  • Infrastructure Management is not required: Infrastructure management is not required when using public cloud services.
  • No Maintenance cost: The service provider handles all maintenance.
  • Dynamic Scalability: On-demand resources are available to meet the demands of your business.

Another example of public cloud deployment is the platform-as-a Service (PaaS) model. Learn more about it in our previous post, ‘What is PaaS in Cloud Computing: Definitions and How It Works‘.

2. Private Cloud Deployment

Private cloud deployment involves a dedicated infrastructure for a single organisation, which provides greater control, security, and customisation. It is widely used in industries with strict data privacy and regulatory requirements, including finance, healthcare, and government. Private cloud deployments can be done on-premises or through a third-party service provider.

Some benefits of private cloud deployment include:

  • Greater Control: The property is owned exclusively by you. You take total control over policy, user behaviour, IT operations, and service integration.
  • Data Security and Privacy: It works well for keeping company data private, to which employees with permission can only access. It is possible to achieve better security and access by dividing up resources within the same infrastructure.
  • Supports Legacy Systems: This method is made to function with older systems that aren’t able to connect to the public cloud.
  • Customisation: Using a private cloud enables an organisation to customize its solution to match its unique requirements, in contrast to a public cloud deployment.

3. Hybrid Cloud Deployment

Hybrid cloud deployment combines public and private cloud environments, allowing data and applications to be shared across them. This model provides flexibility, cost optimisation, and the ability to handle varying workload demands. Organisations can use the public cloud for non-sensitive operations while storing critical data in a private cloud, achieving a balance of security and scalability.

There are several advantages to the hybrid cloud model, including:

  • Flexibility and control: Businesses with greater flexibility can create customized solutions to meet their specific requirements.
  • Cost: Because public clouds offer scalability, you’ll only have to pay for additional capacity if you need it.
  • Security: Data is properly separated, so the chances of data theft by attackers are greatly reduced.

4. Community Cloud Deployment

Community cloud deployment benefits multiple organisations that share common interests, such as regulatory concerns or security requirements. It promotes collaboration and resource sharing within a community while addressing common concerns. Community cloud deployment is often beneficial to industries such as research, education, and non-profit organisations.

Some advantages of the Community Cloud Model include:

  • Cost-effectiveness: Because the cloud is shared by several communities or organisations, it helps to keep costs affordable.
  • Security: A community cloud offers enhanced security.
  • Shared resources: You can share resources, infrastructure, and so on with multiple organisations.
  • Collaboration and data sharing: It works well for both types of activities.

Considerations for Choosing a Cloud Deployment Model

When choosing a cloud deployment model, there are several factors to consider. These factors include the specific needs of your organisation, the level of control and customisation required, as well as compliance and regulatory requirements. It is important to carefully evaluate these factors to ensure that you select the most suitable cloud deployment model for your organisation.

  1. Cost: Public clouds are often more cost-effective due to their pay-per-use model, while private clouds require substantial capital expenditures and ongoing management costs. Hybrid and multi-cloud models can offer a balance between the two, but they may require additional management overhead.
  2. Privacy and Security: Private clouds offer the most control over resources and data, making them ideal for sensitive information. Public clouds have robust security controls, but there is a risk of data breaches or unauthorised access.
  3. Availability: Public clouds are highly available and can be accessed from anywhere, while private clouds ensure on-demand data availability for mission-critical workloads.
  4. Scalability: Public clouds offer superior scalability, allowing businesses to quickly scale up or down as needed. Private clouds can also be scalable, but they may require more planning and resources.
  5. Legal Compliance: Private clouds can be tailored to meet specific legal compliance requirements, while public clouds may have more limited options for customisation.
  6. Ease of Use: Public clouds are generally easier to set up and use, while private clouds may require more technical expertise and management overhead.
  7. Flexibility: Hybrid clouds offer the flexibility to run workloads in both public and private clouds, while multi-cloud models can distribute workloads across multiple providers for cost optimisation and increased fault tolerance.

When making a decision, it is essential to conduct an assessment of your organisation’s needs, including security, compliance, scalability, budget, and specific application requirements. Additionally, consider consulting with cloud experts or leveraging cloud consulting services to help evaluate the best deployment model for your unique circumstances.

While not a cloud deployment model, Software-as-a-Service (SaaS) is one type of software distribution model that greatly benefits from cloud computing services.

Conclusion

To sum up, the choice of a cloud deployment model has a big influence on the IT infrastructure, business processes, and general success of an organisation.

For the purpose of making decisions, it is important to understand the unique characteristics, advantages, and factors related to public, private, hybrid, and community cloud deployments. Organisations can select the best deployment model to promote productivity, creativity, and expansion in the digital age by carefully analysing the specific needs and goals.
