Choosing the right one from the various types of cloud service deployment models is essential. It would ensure your business is equipped with the performance, scalability, privacy, security, compliance & cost-effectiveness it requires. It is important to learn and explore what different deployment types can offer – around what particular problems it can solve.

Read on as we cover the various cloud computing deployment and service models to help discover the best choice for your business.

What Is A Cloud Deployment Model?

It works as your virtual computing environment with a choice of deployment model depending on how much data you want to store and who has access to the Infrastructure.

Different Types Of Cloud Computing Deployment Models

Most cloud hubs have tens of thousands of servers and storage devices to enable fast loading. It is often possible to choose a geographic area to put the data “closer” to users. Thus, deployment models for cloud computing are categorized based on their location. To know which model would best fit the requirements of your organization, let us first learn about the various types.

Cloud Deployment Model

Public Cloud

The name says it all. It is accessible to the public. Public deployment models in the cloud are perfect for organizations with growing and fluctuating demands. It also makes a great choice for companies with low-security concerns. Thus, you pay a cloud service provider for networking services, compute virtualization & storage available on the public internet. It is also a great delivery model for the teams with development and testing. Its configuration and deployment are quick and easy, making it an ideal choice for test environments.

Cloud Deployment Model

Benefits of Public Cloud

  • Minimal Investment – As a pay-per-use service, there is no large upfront cost and is ideal for businesses who need quick access to resources
  • No Hardware Setup – The cloud service providers fully fund the entire Infrastructure
  • No Infrastructure Management – This does not require an in-house team to utilize the public cloud.

Limitations of Public Cloud

  • Data Security and Privacy Concerns – Since it is accessible to all, it does not fully protect against cyber-attacks and could lead to vulnerabilities.
  • Reliability Issues – Since the same server network is open to a wide range of users, it can lead to malfunction and outages
  • Service/License Limitation – While there are many resources you can exchange with tenants, there is a usage cap.

Private Cloud

Now that you understand what the public cloud could offer you, of course, you are keen to know what a private cloud can do. Companies that look for cost efficiency and greater control over data & resources will find the private cloud a more suitable choice.

It means that it will be integrated with your data center and managed by your IT team. Alternatively, you can also choose to host it externally. The private cloud offers bigger opportunities that help meet specific organizations’ requirements when it comes to customization. It’s also a wise choice for mission-critical processes that may have frequently changing requirements.

Cloud Deployment Model

Benefits of Private Cloud

  • Data Privacy – It is ideal for storing corporate data where only authorized personnel gets access
  • Security – Segmentation of resources within the same Infrastructure can help with better access and higher levels of security.
  • Supports Legacy Systems – This model supports legacy systems that cannot access the public cloud.

Limitations of Private Cloud

  • Higher Cost – With the benefits you get, the investment will also be larger than the public cloud. Here, you will pay for software, hardware, and resources for staff and training.
  • Fixed Scalability – The hardware you choose will accordingly help you scale in a certain direction
  • High Maintenance – Since it is managed in-house, the maintenance costs also increase.

Community Cloud

The community cloud operates in a way that is similar to the public cloud. There’s just one difference – it allows access to only a specific set of users who share common objectives and use cases. This type of deployment model of cloud computing is managed and hosted internally or by a third-party vendor. However, you can also choose a combination of all three.

Cloud Deployment Model

Benefits of Community Cloud

  • Smaller Investment – A community cloud is much cheaper than the private & public cloud and provides great performance
  • Setup Benefits – The protocols and configuration of a community cloud must align with industry standards, allowing customers to work much more efficiently.

Limitations of Community Cloud

  • Shared Resources – Due to restricted bandwidth and storage capacity, community resources often pose challenges.
  • Not as Popular – Since this is a recently introduced model, it is not that popular or available across industries

Hybrid Cloud

As the name suggests, a hybrid cloud is a combination of two or more cloud architectures. While each model in the hybrid cloud functions differently, it is all part of the same architecture. Further, as part of this deployment of the cloud computing model, the internal or external providers can offer resources.

Let’s understand the hybrid model better. A company with critical data will prefer storing on a private cloud, while less sensitive data can be stored on a public cloud. The hybrid cloud is also frequently used for ‘cloud bursting’. It means, supposes an organization runs an application on-premises, but due to heavy load, it can burst into the public cloud.

Cloud Deployment Model

Benefits of Hybrid Cloud

  • Cost-Effectiveness – The overall cost of a hybrid solution decreases since it majorly uses the public cloud to store data.
  • Security – Since data is properly segmented, the chances of data theft from attackers are significantly reduced.
  • Flexibility – With higher levels of flexibility, businesses can create custom solutions that fit their exact requirements

Limitations of Hybrid Cloud

  • Complexity – It is complex setting up a hybrid cloud since it needs to integrate two or more cloud architectures
  • Specific Use Case – This model makes more sense for organizations that have multiple use cases or need to separate critical and sensitive data

A Comparative Analysis of Cloud Deployment Models

With the below table, we have attempted to analyze the key models with an overview of what each one can do for you:

Important Factors to Consider Public Private Community Hybrid
Setup and ease of use Easy Requires professional IT Team Requires professional IT Team Requires professional IT Team
Data Security and Privacy Low High Very High High
Scalability and flexibility High High Fixed requirements High
Cost-Effectiveness Most affordable Most expensive Cost is distributed among members Cheaper than private but more expensive than public
Reliability Low High Higher High

Making the Right Choice for Cloud Deployment Models

There is no one-size-fits-all approach to picking a cloud deployment model. Instead, organizations must select a model based on workload-by-workload. Start with assessing your needs and consider what type of support your application requires. Here are a few factors you can consider before making the call:

  • Ease of Use – How savvy and trained are your resources? Do you have the time and the money to put them through training?
  • Cost – How much are you willing to spend on a deployment model? How much can you pay upfront on subscription, maintenance, updates, and more?
  • Scalability – What is your current activity status? Does your system run into high demand?
  • Compliance – Are there any specific laws or regulations in your country that can impact the implementation? What are the industry standards that you must adhere to?
  • Privacy – Have you set strict privacy rules for the data you gather?

Each cloud deployment model has a unique offering and can immensely add value to your business. For small to medium-sized businesses, a public cloud is an ideal model to start with. And as your requirements change, you can switch over to a different deployment model. An effective strategy can be designed depending on your needs using the cloud mentioned above deployment models.
