What is Cloud Deployment Model?
A cloud deployment model defines your cloud architecture and computing resource scalability, and you can alter your services and how much of the build you own. Cloud deployment types define relationships between your users and the cloud infrastructure. You can choose from various deployment models depending on how much data you want to keep and who will have access to the Infrastructure. It functions as your virtual computing environment.
Types of Cloud Deployment Models
The following are the four primary types of cloud deployment models.
- Private Cloud
- Public Cloud
- Community Cloud
- Hybrid Cloud
Figure 01: Private Cloud ModelThe private cloud deployment paradigm is about a dedicated environment for one user or a client. Since all the hardware is yours, you do not share it with other users. Users can host a private cloud in a company’s data centre, a colocation facility run by a third party, or a private cloud provider offering standard public shared multi-tenant cloud architecture. Although using a private cloud solution requires significantly more IT experience than using a public cloud, it gives enterprises more control and better security for their private cloud servers.
Private cloud features include a non-uniformly designed infrastructure, a meager chance of data leaks, end-to-end control, and a weak service level agreement (SLA). However, you can still apply custom policies to make it simple to manage resources and internal Infrastructure.
- Public Cloud Model
As the name suggests, this model is accessible to the public. Public cloud deployment strategies are ideal for businesses with varying and growing demands. Additionally, it’s a perfect option for companies with few security concerns. Thus, you pay a cloud provider for internet-based storage, virtualised computing, and networking services. Additionally, it is an excellent delivery mechanism for teams that work on development and testing. It is the best option for test environments because of its rapid and simple configuration and deployment.
Public clouds are ideal for organisations that require immediate access to resources. Public clouds do not require hardware setup, and the cloud service providers fully cover all infrastructure costs. The public cloud can therefore be used without an internal team.
But there are some limitations as well. It may not offer total security from cyberattacks and may introduce vulnerabilities because it is accessible to everyone. Additionally, there will be dependability problems because a variety of users can use the same server network, which increases the likelihood of failures and outages.
- Community Cloud Model
This architecture enables a collection of organisations to access the system and services. Several organisations share the Infrastructure in a specific community. Organisations may administer it internally or by a third party.
If further explained, a community cloud is a single, sector-specific solution that combines the advantages and capabilities of various cloud types (Banks, insurance, government, enterprise, etc.). It is also appropriate for organisations working on related applications, research topics, or projects that require the same resources. A community cloud is a private network that only a small number of individuals can access. It can be designed and managed by one or all members of an organisation and a third-party provider, making it customisable.
There are many benefits of deploying the cloud as a community cloud model. Some of them are as follows.
- A community cloud offers superior performance and is significantly less expensive than private and public clouds.
- Customers can work considerably more productively if a community cloud’s protocols and setup follow industry standards.
Some issues apply to the community cloud deployment model.
One must take precautions when keeping data in a community cloud since it may be accessible to others because it is kept in one location. Further, allocating governance, security, and financial obligations among groups takes a lot of work.
- Hybrid Cloud Model
A hybrid cloud is a computing environment that combines external public clouds with on-premises private clouds. Usually, this involves attaching a public cloud to a data centre that is located on-site. Other personal assets, such as edge devices or clouds, may also be connected. A company can deploy its most sensitive workloads in an on-premises cloud with hybrid cloud computing while hosting less crucial resources on a third-party, public cloud provider. Companies can benefit from private and public cloud models using this strategy.
Following are some core benefits of hybrid clouds.
- Flexibility: A hybrid cloud arrangement uses both conventional systems and the most recent cloud technology without making a total vendor commitment. Businesses can move workloads between their on-premises Infrastructure and a vendor’s public cloud when necessary.
- Cost Management: Organizations that use private clouds are the ones who own and manage the data centre infrastructure, which comes at a high capital investment and fixed cost. On the other hand, public cloud resources and services are treated as varying and ongoing costs. Users of hybrid clouds can run workloads in whichever environment is more economical.
- Agility and scalability: Compared to a company’s physical data centre, a hybrid cloud gives greater resource possibilities via a public cloud provider. As a result, it is easier to deploy, provide, and scale resources to accommodate spikes in demand. When demand exceeds the capacity of the nearby data centre, a business might burst an application to the public cloud to gain more scale and power.
Choosing the Best Cloud Deployment Models
Each method works for only some cloud deployment models. Usually, this involves attaching a public cloud to a data centre that is located on-site. Start by analysing your requirements, then think about the support your application needs. Ease of use, cost, scalability, compliance, and privacy are a few factors you can consider before making a choice.
Each cloud deployment type can improve your company. An ideal starting point for small to medium-sized organisations is a public cloud model. You can switch to a different deployment strategy. Using the cloud deployment models outlined above, an efficient plan may be created based on your demands.
