What cloud model is owned and operated by an organization for its own use?
The demand for cloud computing has given rise to different types of cloud deployment models. These models are based on similar technology, but they differ in scalability, cost, performance, and privacy. Show
It is not always clear which cloud model is an ideal fit for a business. Decision-makers must factor in computing and business needs, and they need to know what different deployment types can offer. Read on to learn about the five main cloud deployment models and find the best choice for your business. What is Cloud Deployment?Cloud deployment is the process of building a virtual computing environment. It typically involves the setup of one of the following platforms:
Deploying to the cloud provides organizations with flexible and scalable virtual computing resources. A cloud deployment model is the type of architecture a cloud system is implemented on. These models differ in terms of management, ownership, access control, and security protocols. The five most popular cloud deployment models are public, private, virtual private (VPC), hybrid, and community cloud.

Public CloudThe public cloud model is the most widely used cloud service. This cloud type is a popular option for web applications, file sharing, and non-sensitive data storage. The service provider owns and operates all the hardware needed to run a public cloud. Providers keep devices in massive data centers. The public cloud deliverynmodel plays a vital role in development and testing. Developers often use public cloud infrastructure for development and testing purposes. Its virtual environment is cheap and can be configured easily and deployed quickly, making it perfect for test environments. Advantages of Public CloudBenefits of the public cloud include:
Disadvantages of Public CloudThe public cloud does have some drawbacks:
Private CloudWhereas a public model is available to anyone, a private cloud belongs to a specific organization. That organization controls the system and manages it in a centralized fashion. While a third party (e.g., service provider) can host a private cloud server (a type of colocation), most companies choose to keep the hardware in their on-premises data center. From there, an in-house team can oversee and manage everything. The private cloud deployment model is also known as the internal or corporate model. Advantages of Private CloudHere are the main reasons why organizations are using a private cloud:
Disadvantages of Private Cloud
Virtual Private Cloud (VPC)A VPC customer has exclusive access to a segment of a public cloud. This deployment is a compromise between a private and a public model in terms of price and features. Access to a virtual private platform is typically given through a secure connection (e.g., VPN). Access can also be restricted by the user’s physical location by employing firewalls and IP address whitelisting.

Advantages of Virtual Private CloudHere are the positives of VPCs:
Disadvantages of Virtual Private CloudThe main weaknesses of VPCs are:
Community CloudThe community cloud deployment model operates as a public cloud. The difference is that this system only allows access to a specific group of users with shared interests and use cases. This type of cloud architecture can be hosted on-premises, at a peer organization, or by a third-party provider. A combination of all three is also an option. Typically, all organizations in a community have the same security policies, application types, and legislative issues. Advantages of Community CloudHere are the benefits of a community cloud solution:
Disadvantages of Community CloudThe main disadvantages of community cloud are:
Hybrid CloudA hybrid cloud is a combination of two or more infrastructures (private, community, VPC, public cloud, and dedicated servers). Every model within a hybrid is a separate system, but they are all a part of the same architecture. A typical deployment model example of a hybrid solution is when a company stores critical data on a private cloud and less sensitive information on a public cloud. Another use case is when a portion of a firm’s data cannot legally be stored on a public cloud. The hybrid cloud model is often used for cloud bursting. Cloud bursting allows an organization to run applications on-premises but “burst” into the public cloud in times of heavy load. It is an excellent option for organizations with versatile use cases.

How to Choose Between Cloud Deployment ModelsTo choose the best cloud deployment model for your company, start by defining your requirements for:
Answers to these questions will help you pick between a public, private, virtual private, community, or hybrid cloud. Typically, a public cloud is ideal for small and medium businesses, especially if they have limited demands. The larger the organization, the more sense a private cloud or Virtual Private Cloud starts to make. For bigger businesses that wish to minimize costs, there are compromise options like VPCs and hybrids. If your niche has a community offering, that option is worth exploring.

Which type of cloud deployment model is owned and operated only by the organization?Private Cloud
That organization controls the system and manages it in a centralized fashion. While a third party (e.g., service provider) can host a private cloud server (a type of colocation), most companies choose to keep the hardware in their on-premises data center.
Which cloud is owned and operated by the Organisation that uses the resources from that cloud?The cloud resources (like servers and storage) are owned and operated by a third-party cloud service provider and delivered over the internet. With a public cloud, all hardware, software and other supporting infrastructure are owned and managed by the cloud provider. Microsoft Azure is an example of a public cloud.
Which type of cloud is best if you want to use IT for your own organization?Customers create and use a private cloud that's deployed, configured, and managed by a third-party vendor. Managed private clouds are a cloud delivery option that helps enterprises with understaffed or underskilled IT teams provide better private cloud services and infrastructure.
What is a cloud that is operated for a single organization?A private cloud, also known as an internal or corporate cloud, is dedicated to the needs and goals of a single organization whereas public clouds deliver services to multiple organizations.
