There are different deployment models while using cloud computing. A cloud deployment model represents a specific cloud environment, primarily distinguished by holding, size, and access. Each deployment model defines according to the infrastructure. Three types of deployment models offer different levels of management, security, and flexibility. Deciding which deployment model you should use is the most critical decision for a business.
Deployment Models of Cloud Computing
1. Public Cloud
A Public Cloud model is a cloud model where a vendor utilizes available shared infrastructure, including computing, storage, database, network resources, and many more resources that can be provisioned and accessed on-demand services over the internet for Public usage. The most common public cloud usage is testing, development, file sharing, and email services. The public cloud is the greatest example of hosting sites that enables various user for public use. It allows anyone over the web can use the services but with less security management. The client will never see the hardware or physical things in a public cloud.
Example: Google App Engine etc.
2. Private Cloud
The private cloud is just the opposite of the public cloud. It refers to a single user or organization, and a private cloud is more costly than a public cloud. It is privately hosted, managed, or owned by an individual company giving direct control of its data. Enterprises that wish to keep a tighter grasp of security control may adopt this architecture. It has greater data security and privacy for storing information to which only recognized staff has access to it. The private cloud has its customized services and deployment to meet business needs. They secure our data with the help of firewalls and internal hosting.
Examples: HP data centers, Microsoft, Ubuntu, etc.
3. Hybrid Cloud
An organization uses interconnected private and public cloud infrastructure in a hybrid cloud. Many corporations use this model when they need public and private combinations for their business. This model scales up its IT structure rapidly with high-security benefits. You may host your app in a safe environment with the advantage of the public cloud’s low costs. This model may be used for businesses with greater flexibility and moving workloads.
Examples: Azure stacks, Goggle Anthony, and Dell are leading providers of Hybrid Cloud.
4. Community Cloud
This type of model is accessible to a group or organization. The community cloud is comparatively more secure than the public cloud but less secure than the private cloud.
It is also suitable for organizations working on a joint project, research topic, or application and accessing identical resources. A community cloud allows organizations to communicate, share and collaborate without depending on public clouds. Community cloud is used in the financial sector, Research and education, and the public sector.
Examples: Netapp and Lyft companies use the cloud for federal agencies.
The deployment model of cloud computing consists of public, private, hybrid, and community clouds with unique features and service suites. All the models have different suites with different pricing models.
