Although the term “cloud” often gives cloud computing a somewhat mystical connotation, in reality, it isn’t all that different from traditional computing architecture. Cloud computing still relies upon the same physical server hardware that forms the backbone of any computer network. The difference cloud computing deployment models is that cloud architecture makes the processing power and storage capacity of that hardware available over the internet. This allows cloud providers to use servers distributed around the world to form a consolidated, powerful computing network that can be accessed from any internet connection.

A newer architectural approach involves public cloud providers offering hybrid cloud platforms that extend public cloud services into private data centers. With a private cloud, organizations own and operate the data center infrastructure, which requires significant capital expense and fixed costs. Alternatively, the public cloud offers resources and services that are accounted as variable and operational expenses. Hybrid cloud users can choose to run workloads in whichever environment is more cost effective. The primary advantage of a hybrid cloud model is its ability to provide the scalable computing power of a public cloud with the security and control of a private cloud.

What Is Cloud Deployment? Why We Need It?

A misconception about both colocation and the cloud is that they’re an “either-or” investment. As mentioned, the two can be deployed together as part of a hybrid cloud model, enabling more streamlined application management. For instance, a business may want to run its mission-critical systems within the walls of their colocation facility but use a cloud environment for development and testing. A colocation provider can create a secure path to the cloud and allow this business to move necessary applications and data to and from the cloud seamlessly. The purpose of a multi-cloud model is versatility and specialization. In enterprise-level organizations, for example, not every department has the same cloud needs.

IgaaS is an attractive model for most small-medium businesses because it allows for efficient B2B integration at minimal infrastructure cost. Community clouds are exclusive to organizations in a similar niche and share common interests such as compliance Big Data Visualization standards, security measures and policies. While all of these are strengths, unfortunately, they come with a downside as well. The shared storage and bandwidth can create issues with prioritization and performance as servers adjust to demands.

Explaining Deployment Model

It is an excellent option for organizations with versatile use cases. Many enterprises have now started adopting cloud computing to enhance their business and manage it better. Cloud services such as the hybrid cloud are provided by third party vendors. Hybrid cloud is a term used for describing integration of two or more clouds, be it private, community or public.

The connection also can involve other private assets, including edge devices or other clouds. Though the answer to which cloud model is an ideal fit for a business depends on the computing and business needs of your organization. Choosing the right one from the various types of cloud service deployment models is essential. This would ensure your business is equipped with the performance, scalability, privacy, security, compliance & cost-effectiveness it requires. It is important to learn and explore what different deployment types can offer – around what particular set of problems it can solve.


It is also essential for an organization to think about cloud migration to develop a scenario to leave the CSP without any losses of IT-Services and data and with a predictable amount of investment Mobile App Development Process and manpower. Applying the Five-Phase-Model of secure cloud migration will ensure this. Changes to an operational environment are inevitable as a system undergoes routine maintenance.

  • The second type of hybrid cloud model also runs most applications and houses data in a private cloud environment, but outsources non-critical applications to a public cloud provider.
  • The private cloud model typically uses on-premises architecture, either in a company’s local data center or a separate physical infrastructure provided by a third party.
  • This level of customization can be tremendously valuable for smaller companies that have a very clear idea of what they need from their infrastructure and it should be optimized to deliver superior services.
  • With the increasing needs of new-age patients, organizations must consider the digital transformation route to drive growth and efficiency.
  • A Private Cloud is different to a Public Cloud in that the infrastructure is Privately hosted, managed, and owned by the individual company using it, giving greater and more direct control of it’s data.
  • There’s also the risk of an unpatched security vulnerability in the cloud architecture exposing customers to risk.
  • The hardware and software are owned and managed by the user or leased from the IT service provider/cloud service provider and provide self-service access to compute resources to users in their organization only.

Since functions need to provision resources each time they run, there can be slight performance lags if the application requires a lot of computing power or executes during peak usage times. Applications also have to be stateless, so they can’t store data locally. Most FaaS services are available through major cloud providers like AWS and Azure, which can result in vendor lock-in. PaaS is extremely helpful for any company that develops software and web-based applications. Many of the tools needed to develop for multiple platforms can be quite expensive. By using PaaS, customers can access the development tools they need, when they need them, without having to purchase them outright.

#3 What Is Community Cloud?

Large organizations will benefit from the private cloud, whereas smaller businesses will most likely be public cloud. As cloud computing continues to evolve, businesses will continue to shift back and forth through these four major paradigms. Every organization has to decide the cloud deployment model on the basis of its requirements.

With IaaS, the customer can purchase, install, configure, and manage any software they need to use, including things like operating systems, middleware, applications, business analytics, and development tools. Highly scalable, companies only pay for the infrastructure they use, allowing them to scale their computing needs as needed without having to build out additional capacity. Of course, for many organizations, the choice between a hybrid cloud model and a multi-cloud model is a false dichotomy. There’s no reason why a multi-cloud environment can’t incorporate the features of a hybrid cloud. On the other hand, hybrid cloud models offer a lot of advantages. Since they only involve the interconnections between two environments, they are easier to set up and scale.

Cons Of Private Cloud Model:

These models differ in terms of management, ownership, access control, and security protocols. A community deployment model largely resembles a private one; the only difference is the set of users. While a private type implies that only one company owns the server, in the case of a community one, several organizations with similar backgrounds share the infrastructure how to create a location based app and related resources. Example of such a community is where organizations/firms are there along with the financial institutions/banks. A multi-tenant setup developed using cloud among different organizations that belong to a particular community or group having similar computing concern. There is no one-size-fits-all approach to picking a cloud deployment model.

At the executive level, CIOs will find the cost efficiencies and versatility of multi-cloud strategies appealing because it gives them the power to leverage providers against one another to drive down IT costs. The great advantage of a public cloud is its versatility and “pay as you go” structure that allows customers to provision more capacity on demand. Not only does this make your system scalable, but it does so in a way that doesn’t require a large capital expenditure.

It means the deployment model of hybrid cloud was very cost-effective and highly secure. The private cloud did all the critical tasks in the hybrid model, and the public cloud performed all the non-critical cloud computing deployment models tasks. In the private cloud deployment model, we assign a section of the cloud platform to any single organization system. Only this particular organization can able be to use the cloud service privately.

Is Azure Storage account IaaS or PaaS?

Azure provides software as a service (SaaS), platform as a service (PaaS) and infrastructure as a service (IaaS).

From the different types in the sky to those that occupy that magical space in the computing world, different kinds have different purposes and characteristics. The Private Cloud Model allows systems and services to be accessible within an organization. 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. There isn’t a deployment model/type that is automatically more secure than another.

Why Cloud Computing In Banking Industry?

Security is a concern for public cloud because of the multi-tenancy approach. The key differentiator to keep in mind is that multi-cloud models involve using separate cloud environments to perform separate tasks. If an organization needs its IT infrastructure to be able to accommodate the conflicting demands of different departments, then it probably needs to pursue a multi-cloud deployment. ‘Internal Cloud’ means artificial intelligence vs. machine learning that it allows the accessibility of systems and services within a specific boundary or organization. The cloud platform is implemented in a cloud-based secure environment that is guarded by advanced firewalls under the surveillance of the IT department that belongs to a particular organization. Private clouds permit only authorized users, providing the organizations greater control over data and its security.

In the above figure, organization A was there who set up their cloud for their company. There will be some resources on the section of that cloud, and only the trusted user ” ABC, ” ” XYZ ” as mention above of that organization can use these cloud services. In the above figure, different users A, B, C, and D accessed the public cloud resources which were placed in it by different IT companies. And all these resources were monitored by a third party, which was an administrator of the public cloud.
