There are four most popular cloud deployment models in cloud computing. These are private, public, community cloud, and hybrid clouds. Few other distributed models like poly clouds, multi-cloud are not much widespread as such.
Cloud Deployment Models
This article will first figure out the cloud deployment model in detail, and then we will cover the most popular and essential deployment models of cloud computing. Environment parameters make server configuration of cloud deployment models, and those environmental parameters are also proprietorship and accessibility parameters of the deployment infrastructure and the size of storage. Depending on who controls the infrastructure, deployment types can also vary irrespective of server physical location and cloud application deployment.
Type of Cloud Deployment Models
Organizations should choose cloud deployment models that make maximum use of their computing type. There are few things to consider to be able to select the best model for your company. These are networking, available resources, and storage requirements. It also depends on the business goals.
Now let’s discuss the types of cloud deployment models.
1. Public Cloud Deployment Model
In public cloud computing, clouds are made available to the general public, and all the data are stored and created on third-party services. The infrastructure of cloud computing belongs to the organization which is providing cloud computing services. They are responsible for managing and administering the pool of resources, which is why companies hiring cloud computing don’t need to have their maintenance team or any hardware resources on their own.
Cloud computing services are offered through the internet using the SaaS deployment model, and providers offer all the resources and services for free based on the plan opted. Users can decide to upgrade or downgrade their services according to the requirements.
All parts of a cloud-based application run in cloud-only in any cloud-based application as it is deployed completely in the cloud. To take benefits of cloud application either need to be migrated or to be created from existing infrastructure. Cloud-based applications can either use a very high level of service or be made on low-level infrastructure to provide abstraction from scaling, architecting, and managing resources and core infrastructure.
In the public cloud, we get hassle-free infrastructure management. We don’t have to deploy our own team to manage infrastructure because, in this type of cloud computing, the third party takes care of all the infrastructures related to maintenance and other care of the resources. You can focus on managing and maintaining your software. You can use all the setup in a simple and uncomplicated way.
Benefits of a Public Cloud
High Scalability: In the public cloud, the capacity of the cloud can be upgraded or downloaded according to the increase or decrease in requirements of the company.
Economical: Users do not need to invest in resources, hardware, or infrastructure. They can only pay for the usage of services and resources.
High uptime: You get 24 x 7 uptime of a network and services in the public cloud. The third-party makes sure that the availability of infrastructure and average operative time is qualitative.
Drawbacks of Public Cloud:
Less Reliability: Reliability in the public cloud is compromised. Public cloud experience malfunction and outrageous problem. This can cause a collapse in storage.
Data Privacy Issue: There is a probability of breach of data security because physical access to the data on the public cloud is prone to theft and counterfeit in the public cloud. Users or customers do not have control over who is accessing the information at what time.
The Lack of a Bespoke Service
Cloud service providers sometimes fail to fulfill complex requirements because they have standardized service options.
2. Private Cloud
There is not much difference between private cloud and public cloud architecture deployment models. Still, the difference between both is that the public cloud is open to the general public, while in a private cloud, services are limited to a specific company. This is the reason private cloud sometimes is also known as internal cloud or corporate model.
Private cloud services are either hosted on a company’s premises or externally. Irrespective of the physical location of a server, cloud infrastructure and all the associated hardware are meant to be used only by a particular company.
The private cloud is used to deploy resources on-premises. We use virtualization as well as resource management tools for this purpose. There are not many benefits of private cloud computing, but it is sometimes required to make dedicated resources available.
Benefits of a Private Cloud:
- Flexible development and high scalability: Companies can customize resources and infrastructure based on their requirements.
- High-security Reliability and Privacy: Only authorized persons are used to access resources of a private cloud server, so it is the most secure cloud deployment model.
Disadvantages of a Private Cloud
High cost: The cost of the private cloud as compared to the public cloud is relatively very high.
There is a need for extensive expenses on the training of staff and maintenance of hardware and software. This cloud computing model is not meant for small organizations, even when comparatively secure and flexible.
3. Community Cloud
Specification of a community cloud is similar to that of a private cloud. It is only different from the private clouds in a set of users. Another difference is that a private cloud can only be used by one company. In contrast, in a community cloud, multiple organizations with similar backgrounds can use cloud-related resources and infrastructure.
The privacy security and performance of multiple organizations are similar. They can use community cloud, as is clear from the name. This kind of cloud service is meant to be used by the community of companies. All its users share the cost of community clouds, and a centralized cloud facilitates project development, implementation, and management.
Benefits of Community Cloud
- Reduced cost.
- Batter privacy, reliability, and security.
- Easy collaboration of data and sharing of resources.
Disadvantages of Community Cloud:
- The cost of a community cloud is relatively high as compared to a public cloud.
- Bandwidth capacity storage is being shared among multiple organizations.
- It is a less commonly used cloud deployment model.
Hybrid Cloud Deployment Model
When we need to connect an application sitting on a cloud with the interest of not within the cloud, we use the hybrid deployment method. This deployment method is of utmost importance when an organization needs to grow and connect on-premises Infrastructures and resources to the applications hosted on the cloud already. AWS can help you to achieve this goal of hybrid deployment. To know more about this, you can learn here.
Advantages of Hybrid Cloud
- Batter privacy, security, and improved reliability.
- Better flexibility and scalability.
- Reasonable prices.
After considering the technical and business requirement and the specification of any organization carefully, each deployment model is the pre-request site for selecting a deployment cloud model. This is the most important and challenging task. It is always recommended to opt for a professional to select the best cloud computing deployment model for your company.
Based on the requirements and expectations of a particular organization, experts can help choose the best model to fit the requirement of any company. This will improve the performance and reduce security issues and risks in the future of any organization while taking services of any SaaS deployment model.
