Most of the business organizations are now focussing on switching into different types of Cloud deployment models to cut down the capital expenditure and business operational costs. Another reason for opting out this popular technology by various organizations is rapid business growth.
For those who do not know much about Cloud Computing, let us begin with an introduction to Cloud Computing. Cloud Computing is a kind of computing that primarily depends upon resource sharing in place of handling applications and programs by individual servers and devices. All the functions in Cloud Computing are enabled by using the internet. Here, Cloud is a term that stands for the internet.
Cloud Computing can perform a range of functions through the internet such as data storage and virtual servers. However, Cloud also brings security challenges and risks for IT experts due to the presence of internet. These risks can cost you more for your organizations.
Therefore, it is essential for you to know your requirements before going ahead with any of its deployment models present on Cloud.
Primarily, there are four deployment models of Cloud Computing and here in this post, we are going to discuss all of them along with their functions.
1. Private Cloud
Private Cloud which is also called internal cloud is a platform powered by the Cloud-based secure environment. It is supported by a firewall, which is monitored under the supervision of IT experts of organizations. The authorized users are the only ones who can access private Cloud. Not only this, one also gets more control over the applications and data with the private cloud.
Although this deployment model of Cloud is not cost-efficient still it has lots of values for security purpose. Initially, when businesses started off to implement Cloud-based services, many of them had faced a lot of challenges and concerns about data security.
These concerns are completely ruled out by Private Cloud as this hosting model is correctly built and created for a particular client only. All the security issues are sorted out via secure access VPN or within a firewall system of the client.
For those who always consider quality, performance and internet availability as their top priority, Private Cloud is the best-suggested approach to go. Majority of federal agencies and related organizations are opting for the private model. You only have to pay what you have used as provided by the service providers which means it is also economical.
2. Hybrid Cloud
Hybrid Cloud is a type of Cloud Computing which is integrated into more than two cloud servers i.e. Public, Private and Community Clouds. You will get multiple deployment models which are bound together but remain separate entities.
A Hybrid Cloud allows the users to enhance the capabilities by providing assimilation and customization with other Cloud packages. Here the resources are controlled and managed by in-house or external service providers. The workloads could be exchanged between the private and public Cloud as per the demand.
Hybrid hosting is enabled with lots of features like flexibility, security and scalability. Those who are ready to take some challenges like network connectivity issues, capital expenditures and interface compatibility, Hybrid Cloud is simply the best option to go.
NASA is one of the best examples of the users of Hybrid Cloud Computing. Its Cloud Computing project is using Private Cloud whereas research and development wing is using the public cloud to share data sets with external members.
3. Public Cloud
As the name suggests, Public Cloud is that deployment model of Cloud Computing in which Cloud services are opened on a network which is accessible for public use. In this model, you can provide infrastructure and services to multiple clients with the help of service providers.here is not any particular difference between Private and Public Cloud except the security concerns. Public Cloud subscribers get an increased level of security by the Cloud service providers.
There is no particular difference between Private and Public Cloud except the security concerns. The Public Cloud subscribers get an increased level of security by the Cloud service providers.
This model is deployed for those business organizations where there is a requirement of load management because here applications are used by lots of users. This also brings down the capital expenditure and reduces the operational costs incurred in businesses. Google is one of the perfect examples for Public Cloud.
4. Community Cloud
Community Cloud is a hosting in which the entire setup is mutually shared between a number of organizations which belong to a particular community such as banks. All the concerned community members in Community Cloud share similar policy, security, and performance.
Community Cloud is internally managed. You can also take the help of external service providers. The primary objective for opting this model is to achieve organizational goals. It can be hosted internally or externally. It is a cost saving model as the expenses are to be borne by the community members.
This is best suited for those organizations, who are working on joint ventures, research and tenders which require a centralized ability for project management.
You can now understand that each service needs some business deployment models. These are different from each other and can be suited as per your requirements.
Bigger organizations are comfortable with Private Cloud, on the other side, small-scale businesses should go for Public Cloud. You can shift from one model to another as per your business needs evolve anytime.
