When it comes to cloud deployment models, there are four main types; public, private, community, and hybrid. In addition to these four main cloud deployment models, there are also distributed clouds such as multi-clouds and poly clouds, but these are not as widespread.
Before we cover the essentials of cloud computing deployment models, let's first ask, what is a cloud deployment model? They are a specific configuration of environment parameters like the proprietorship and accessibility of the deployment infrastructure as well as the storage size; this means deployment types can vary depending on where the infrastructure is located and who controls it.
In order to make the most of cloud deployment models, a company should pick the model that suits its business needs. However, to find the right type for your organization, you will need to consider your networking, storage, and computing requirements as well as your company's available resources and overall business goals while weighing up the pros and cons of each cloud deployment model.
Public Cloud: What Is It?
As the name suggests, public clouds are available to the general public with the data created and later stored on third-party servers. As the server infrastructure belongs to the providers who manage and administer resources, there is no need for companies to buy or maintain their own hardware. Users can scale up the resources they use as required, and providers can offer these services either free of charge or on a pay-per-use basis. Public cloud deployment models are ideal for organizations that have low privacy concerns, and examples of this type of service are Amazon Web Services, Microsoft Azure, and IBM Cloud. AWS, or Amazon Web Services, is one of the most popular types as it offers a wide range of services that assists its users in managing and automating their operational workloads.

Benefits Of Public Cloud
There are many benefits to using a public cloud deployment model, but the top reasons companies with low privacy concerns choose this option is due to hassle-free infrastructure management, high scalability, reduced costs, and 24/7 uptime.
Utilizing a third party to run your cloud infrastructure is convenient and hassle-free as you don't need to develop or maintain your software as it is done for you by the service provider. Additionally, you get the benefit of having your infrastructure set up for you as well as an uncomplicated and user-friendly system. Furthermore, the high scalability of public cloud deployment models means you can easily extend the capacity as your business grows and your requirements increase.
As you pay for the service provider to set up and run your cloud deployment model, there is no need for your company to invest in hardware or software in order to use this system. Moreover, you will also see increased cost savings as the extensive network your service providers supply is available at any time, which will improve your business's operations and ultimately cut back on outgoings due to maintenance.
Private Cloud Explained
There are few differences between public and private cloud deployment models from a technical point of view as the architecture of these cloud services are quite similar. However, private cloud deployments models are not available to the general public; this means that when a company implements a private model, they are the sole owners, which is why it is often referred to as corporate or internal models. When incorporating a private cloud deployment model, instead of third-party servers, the servers are hosted on a private network either externally or on the business's premises. Whether an organization chooses to house its servers in-house or externally, the infrastructure is maintained on a private network alongside software and hardware intended to be used solely by the company that purchases the service.
Once implemented, a defined scope of personnel will have access to the information stored on the private repository, which will provide companies with increased security against anyone in the general public using the cloud. As a result of the data breaches suffered by many businesses over the years, more companies are opting for private cloud deployment in order to minimize risks to their operations.
In contrast to the public models, private cloud deployment models provide a larger scope for infrastructure customization opportunities to suit an organization's needs better. Additionally, private models are also more suitable for enterprises that require higher safeguarding measures for mission-critical business operations or for corporations that have frequently changing requirements. Multiple service providers offer their services on private cloud models such as Amazon, IBM, Cisco, and Dell.
Strengths Of Private Cloud
When it comes to the strengths of a private cloud deployment model, the most significant benefit is its autonomy. These models are bespoke and flexible, allowing companies to develop and scale the infrastructures in any way they need to suit business requirements. Furthermore, private models provide higher security, reliability, and privacy as only authorized individuals have access to resources on the servers.
Understanding Community Cloud
Community cloud deployment models are similar to private models; however, they have a different set of users, and while private cloud models are owned by a single company, community models are shared by multiple enterprises with similar business backgrounds. The multi-tenant data center of community cloud servers assists companies in enhancing their efficiency, especially when working on joint projects. However, this is only the case if all organizations participating in this community model have uniform security, performance, and privacy requirements.
Advantages Of Community Cloud
For companies that regularly need to collaborate with other organizations, community cloud models can help reduce costs, and this is shared across all the users of the service. In addition to improved reliability, security, and privacy, community cloud deployment also provides accessible data sharing for improved collaboration.
What You Need To Know About Hybrid Cloud
As is typically the case with all hybrid products and services, hybrid cloud deployment models encompass the best features of public, private, and community models. These models provide companies with the opportunity to mix and match the function of the three types to suit their business requirements better. As a result of the nature of hybrid models, the benefits vary, but you can usually expect improved security and privacy as well as enhanced flexibility while maintaining cost-effectiveness.
