What are cloud computing deployment models?
The cloud deployment model specifies the type of cloud environment based on ownership, scale, access, and the nature and purpose of the cloud.
A cloud deployment model defines the location and ownership of your servers. It specifies how your cloud infrastructure will appear, what can be modified, and whether services will be provided or you will have to create everything yourself. Cloud deployment categories also define the relationships between the infrastructure and your users.
Public Cloud
The public cloud is the first and most well-known form of cloud computing. Google Translate and Backup & Restore on Huawei handsets are two examples of public cloud computing from our earlier list.
The public cloud enables anyone to gain access to systems and services. Since the public cloud is accessible to everyone, it may be less secure. The public cloud is one in which cloud infrastructure services are made available to the general public or significant industry groups via the Internet. In this cloud model, the infrastructure is owned by the entity providing cloud services, not the consumer. It is a form of cloud hosting that provides easy access to systems and services for customers and users. This type of cloud computing is an excellent illustration of cloud hosting, in which service providers provide services to multiple clients. This arrangement provides storage backup and retrieval services for free, via subscription, or on a per-user basis. Example: Google AppEngine etc.
Internet-based IT services comparable to utilities are accessible to the public. Public clouds are frequently designed and managed by cloud service providers. End users pay a subscription charge to access cloud-based resources or services, while the service provider is responsible for all operations, maintenance, and administration.
Private Cloud
Private cloud deployment models are completely opposed to public cloud deployment models. It is a one-on-one setting for one user. (customer). There is no requirement to share hardware with others.
The difference between private and public clouds is how the hardware is managed. It is also known as the “internal cloud” and refers to the capacity to access systems and services within a particular organization or geographical boundary. The cloud platform is implemented in a cloud-based, secure environment protected by robust firewalls and supervised by the IT department of an organization. The private cloud provides greater control and flexibility over cloud resources.
Hybrid Cloud
Hybrid cloud computing provides the best of both worlds by bridging the public and private realms with a layer of proprietary software. With a hybrid solution, you can host the application in a secure environment while taking advantage of the cost savings of the public cloud. Depending on their requirements, organizations can transfer data and applications between clouds using a combination of two or more cloud deployment methods.
A hybrid cloud architecture results from a company’s decision to keep critical data assets on-premises for maximum security while storing other data in public databases for cost efficiency. Using the pay-per-use model; public clouds provide businesses with cyclical data processing requirements with a highly cost-effective solution. The holiday season is prime computing demand for some online retailers. The hybrid cloud also satisfies the elasticity needs of other applications, such as disaster recovery. Consequently, a private cloud Utilizes a public cloud for disaster recovery and restores data there as necessary.It is possible to run applications on one public cloud while utilizing another for disaster recovery.
