Are you looking for the best cloud computing model for your business? If so, you need to understand the models available, their pros and cons, and their costs. You must also consider your business needs to pick the model that suits you most. There are four cloud deployment models: private cloud, public cloud, hybrid cloud, and community cloud.
Let’s dig deeper and explain more about these models.
Private Cloud
A private cloud, also called a corporate or internal cloud, is used by a single individual or organization and can’t be accessed by the public.
Pros Of Private Cloud
l Control over geographical data location
l Control over security and privacy practices
l Control over how the cloud infrastructure is set up and used
Cons Of Private Cloud
l High set-up cost
l High maintenance cost
l Less resilience and scalability
Who is Private Cloud For?
A private cloud is best if you want to enjoy all the benefits but keep resources confidential from the public. Since private clouds are expensive, they are suitable for big organizations. Companies that sell private clouds include Amazon Web Services, Microsoft, IBM, Oracle, Dell, VMware, and Hewlett Packard Enterprises.
Public Cloud
A public cloud is a cloud infrastructure that is open to the public. It can be operated, managed, and owned by a government, academic, business organization, or a combination of these institutions but exists on the provider’s premises. The public cloud is delivered over the internet, so you need an internet connection to access all the tools and software on a public cloud. Amazon is an excellent hybrid cloud example. It has a vast pool of resources that power its public cloud services.
Pros of Public Cloud
l Easy to use
l Location independence
l Scalable
l Low price (can even be free)
Cons of Public Cloud
Lack of absolute control
Security concerns
Who‘s Public Cloud For?
The public cloud is ideal for medium and small enterprises, especially those with growing or fluctuating demands. The most popular public cloud service providers are Google Cloud Platform, IBM Cloud, Microsoft Azure, and Amazon Web Services (AWS).
Community Cloud
A community cloud is a compromise between private and public clouds. It is a semi-public cloud that only some specified organizations can use. The organizations should have common compliance considerations, policies, security requirements, mission, etc.
Pros Community Cloud
l Cheaper compared to private cloud
l More scalable
l Cloud security and configuration that suit your needs
Cons of Community Cloud
l It is not available in all communities
l You won’t get the full benefits of private or public cloud
Who is Community Cloud For?
This option is best for you if you are in a community of businesses that share common interests. Amazon, AWS GovCloud, and other providers offer community cloud.
Hybrid Cloud
A hybrid cloud is a mixture of two or more different types of clouds. It can be private and public, private and community, community and public, or a combination of all the three.
Pros of Hybrid Cloud
l Safe
l Flexible
l Scalable
Cons of Hybrid Cloud
l More expensive than community or public models
l Difficulty in communication
l Complex
Who‘s Hybrid Cloud For?
A hybrid cloud is suitable for anyone or any organization that wants to benefit from a mixture of different cloud computing models. Hybrid cloud providers include Dell, Cisco, IBM, Hewlett Packard, Rackspace, AWS, VMware, and Microsoft.
When choosing a clouding model, consider your needs and the Cloud Deployment Model’s scalability, privacy, ease of use, security, flexibility, and legal compliance.
