Chapter 3 Cloud Deployment Models

Since the servers belong to service providers that manage them and administer any pool resources, the requirement that a business must buy their own hardware is eliminated. Cloud computing provides huge benefits to companies of all sizes and specifics. A cloud deployment model is a specific configuration of environmental parameters such as accessibility and proprietorship of the deployment infrastructure and storage size. It is defined according to where the infrastructure for the deployment resides and who has control over it. Private Cloud which is also called internal cloud is a platform powered by the Cloud-based secure environment.

Since public cloud computing services can be offered on a “pay for what you use” model, hybrid clouds can reduce overall IT spend while still allowing companies to scale up processing power when they need it. Non-critical tasks such as development and test workloads can be done using public cloud whereas critical tasks that are sensitive such as organization data handling are done using a private cloud. Benefits of both deployment models, as well as a community deployment model, are possible in a hybrid cloud hosting.


Authorized users can access, utilize, and store data in the private cloud from anywhere, just like they could with a public cloud. The difference is that no one else can access or utilize those computing resources. Before we dive into the essentials of the most popular cloud computing deployment models, let’s figure out what a cloud deployment model is exactly.

You can shift from one model to another as per your business needs evolve anytime. 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 cloud computing deployment models issues are sorted out via secure access VPN or within a firewall system of the client. 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.

Cloud Deployment Models: Learn The Differences

Data on a community cloud server may not be incredibly secure because multiple users can access it. Your choice of cloud deployment model will depend on your data security concerns and the needs of your organization. Colocation cloud computing deployment models offers many benefits, but identifying the right providercan be challenging for companies. Perhaps the greatest challenge in selecting a colocation provider is resisting the urge to approach the investment as a commodity.

In a private cloud, the services or solutions are dedicated to a particular organization or business. Private cloud also delivers high-level privacy and security so that sensitive data is not leaked to third party providers.

While the name speaks for itself, a public cloud is a cloud where services are rendered by third-party providers over an open network for public use. It’s available to the general public and data is created & stored on third-party servers. The public cloud deployment model is one of the most commonly used cloud services. It’s a popular option for create restaurant app apps, file sharing, and insensitive data storage. 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. Enterprises who wish to keep a tighter grasp of security control may adopt this architecture.

Public clouds are ideal for lean organizations which focus on dynamic scaling but are dependent on tight budgets. If the cloud were let’s say a mall, a private cloud would be like a company that owns the entire mall. Access and control are also important in terms of being able to meet your needs. How much input might you have in terms of the needs of your business and system? While with a public cloud option some of this will be limited, it’s essential to know that if you are having performance issues that there is an opportunity for you to have input. Large organizations with divisions existing in separate “silos” will typically find that multi-cloud solutions address more of their business needs.

Virtual Private Cloud Model

If there’s a disruption in the data center, workloads fail over to the cloud environment and operate properly via on-demand cloud resources. However, implementation must be handled properly to avoid hybrid cloud backup challenges, such as bandwidth consumption and management complexity. Public cloud is priced on a pay-as-you go model whereby organizations pay only for the capacity best blockchain platform they use, typically a monthly fee. Improperly configured workloads, however, can lead a business to underutilize and overpay for public cloud services. Meanwhile, on-premises computing requires a high upfront investment and additional costs primarily for maintenance. Hybrid cloud offers more resource options via a public cloud provider vs. an organization’s physical data center.

Many colocation providers offer a variety of managed services in addition to space and power. Furthermore, moving to a colocation facility can help reduce your CapEx and simultaneously tap into the latest data center technologies. Cloud deployments are allowing small businesses to reach new customers and are speeding up the pace of scientific development. The advent of virtualized and cloud-based hosting solutions Cloud Application Security gives IT viable options for improving network speed and performance. Arguably, they also equip teams to deliver greater business value by helping reduce overhead and CapEx and enabling infrastructure scalability. Not to mention, operating a data center isn’t a core competency for many businesses, and cloud-based solutions certainly remove data center management tasks from internal IT talent’s to-do list.

Public cloud solutions are readily offered by Microsoft, Google, Amazon and others. Because hybrid cloud architecture comprises multiple environments and types of components, cloud management is a complex task. Fortunately, there are strategies and tools to help resolve the complications of hybrid management and create a streamlined approach across environments.

  • Improperly configured workloads, however, can lead a business to underutilize and overpay for public cloud services.
  • Google Apps for Government is one type of community cloud environment.
  • Because public cloud was based on the pay per use model, the cloud service provider provides resources easily whenever the demand for services comes.
  • Since there are so many similarities between them, it’s helpful to think of cloud computing as a pyramid, comprised of three layers.
  • You can use a VPN connection for connecting with your cloud platform.

In general, a hybrid cloud occurs when a business operating on a private cloud expands and starts using a public cloud, generating in this way a combined environment. Nevertheless, using a combination of both public and private models requires strong IT management and, accordingly, higher investments. Hello and welcome to this lecture where I shall explain some of the different deployment models used when adopting Cloud technology. Typically within Cloud computing, there are three different Cloud model types, each offering different levels of management, flexibility, security and resilience, and these are Public, Private and hybrid. It makes sense from a design perspective to host your infrastructure as close to the geographical region as your customers or end users are, as this will provide the best overall performance for them. As a general rule, you can access your services on the Public Cloud from anywhere as long as you have an internet connection.

Best Cloud Deployment Models Overview

A multi-cloud environment consists of two or more public cloud providers but does not require a private or on-premises component. It is vital you understand the security policies and ownership rights of each deployment model before opting for one. Investing in a cloud deployment model should be focused on the critical nature of the applications, data, and programs.

What are the different models of cloud computing?

Cloud computing is offered in three different service models which each satisfy a unique set of business requirements. These three models are known as Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS).

And it was not that only organization people can able to manage its resources also the third party who was providing the private cloud services would be able to manage it. A hybrid cloud deployment model is a combination of two or more cloud servers as one architecture. With a mix of two or more cloud deployment models, organizations are capable of moving data and applications between different clouds, depending on their purpose.

As cloud technology is providing users with so many benefits, these benefits must have to be categorized based on users requirement. Cloud deployment model represents the exact category of cloud environment based on proprietorship, size, and access and also describes the nature and purpose of the cloud. Most organizations implement cloud infrastructure to minimize capital expenditure & regulate operating costs. A company that has critical data will prefer storing on a private cloud, while less sensitive data can be stored on a public cloud. It means, suppose an organization runs an application on-premises, but due to heavy load, they can burst into the public cloud.

Since the company manages the server, they can tailor the specifics of the cloud service to suit their needs. However, private systems can be costly because of the required upkeep and maintenance. Public cloud infrastructures are cloud services that are available to use by the general public.
