Cloud computing has ushered in an era where access to shared computer resources, like servers and storage, is more accessible than ever. With cloud deployment models, businesses and individuals can access these resources as needed and release them when no longer required. The models determine where data storage takes place, which stakeholders have access to the cloud infrastructure, and the relationship between the cloud and the user.

Types of Cloud Deployment Models
When discussing cloud deployment models in cloud computing, it’s essential to understand their categorization. Based on different factors such as nature, purpose, scale, ownership, and access, there are primarily four models: public cloud, private cloud, hybrid cloud, and community cloud. However, in recent times, a fifth model, known as the multi-cloud, has gained prominence. This article will delve into these deployment models of cloud computing, highlighting their pros and cons, and provide insights into cloud deployment services that may be beneficial for your business.
As the name suggests, anybody can access the infrastructure in a Public Cloud. It is provided over internet to all who want to use the services. This means that the Cloud Service Provider owns the complete infrastructure. The service provider may provide free services such as storage backup and retrieval.
Advantages of Public Cloud
- Low investment with a pay-per-use structure
- No hardware infrastructure is needed
- Elimination of infrastructure management
- No maintenance costs
- On-demand scalability
Disadvantages of Public Cloud
- Accessible to anyone
- Low security
- Minimal or no customization
The access to Private Cloud is for specified users. This type of cloud computing deployment is also called Internal Cloud. This is used by organizations and is used only by internal stakeholders. Hardware is not shared outside the organization.
Advantages of Private Cloud
- Complete command over the environment
- High-level data security
- Maximum privacy control
- Smooth integration of legacy systems
- Customizable to specific organizational needs
Disadvantages of Private Cloud
- Higher investment level
- Hardware infrastructure setup required
- Limited scalability

A Hybrid Cloud is meant to give the best from Private Cloud and Public Cloud. This deployment model in cloud computing integrates additional software layers to ensure data safety while offering cost savings.
Advantages of Hybrid Cloud
- Better flexibility and greater control
- Options for personalization and customization
- Cost effective
- High security is achievable through proper segregation
Disadvantages of Hybrid Cloud
- Complex infrastructure
- Difficulty in management of private and public segments
- Slow data speeds due to public segment latency
This type is meant for use by a group of companies. The Community Cloud is an integration of various cloud environments to meet the requirements of a community, industry, or group of companies. Shared infrastructure internally within the group is possible. Cloud management is either done by one or more parties within the group or by a third party.
Advantages of Community Cloud
- High cost-efficiency due to shared infrastructure and environment
- High-security level
- Resources are shared by multiple companies within the group
- Ease in collaborating and data transfers
Disadvantages of Community Cloud
- High complexity due to shared resources
- Limitation in scalability
- Difficulty to personalize and customize as each member may have different needs
It is similar to Hybrid Cloud where the benefits of Private Cloud and Public Cloud are harnessed. The difference is these environments are resourced from different Cloud Service Providers. Thus, the environments are kept separate.
Advantages of Multi-Cloud
- Use of best features of multiple service providers
- Reduced occurrence of mishaps
- Choice of multiple cloud zones results in reduced latency
Disadvantages of Multi-Cloud
- Complex management process
- Possibility of bottlenecks
- Unsecure as there is a possibility of hacking some environment

How to choose the right type of Cloud Deployment Model?
Selecting the appropriate cloud deployment model depends on various factors. Each entity will have different requirements. It’s essential to factor in privacy regulations and restrictions on data collection when considering which type of cloud deployment models to adopt.
The following factors must be considered.
- Cost is a primary consideration factor. One must be able to decide how much can be paid for using the services.
- Scalability must be considered according to the development plans. Failure to do so may result in difficulties in the future if the model does not allow scaling.
- Ease of use is important as it will decide how cloud computing is managed.
- Compliance with National and International Laws and Regulations must impact the decision process.
- Privacy Regulations must be considered while considering using a cloud computing deployment. There are restrictions on data collection and storage of privacy information.
