An Overview of Cloud Deployment Models
Content
There are many things to take into consideration when selecting a cloud deployment model that is right for your company. The table below summarizes each of them, including the various advantages and disadvantages discussed above. The cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on premise or off premise. Cloud-enabling an application requires that the application be able to interact with databases, middleware, and other applications using standards-based mechanisms such as Web services. Most legacy and client/server applications today do not have this capability natively.
- You can also customize private cloud deployments to meet your requirements, since you control everything, from service integrations to user practices.
- However, private cloud is not a pay-as-you-go expense––you pay for the whole stack, used or not.
- A hybrid model is established when a network link is configured between the Private Cloud to services within the Public Cloud, essentially extending the logical internal network of the Private Cloud.
- On the other hand, the private cloud is where businesses operate their own infrastructure for cloud computing.
- They are considered the most cost-effective deployment models of cloud computing service for any organization.
- Robotic process automation We implement RPA to help companies automate processes and focus on core business.
- Now that you know more about the types of cloud services, you can find out which deployment models your business should choose.
Multi-faceted deployment models employ solutions from several cloud providers at once. This is similar to the hybrid models but allows for multiple public cloud resources. Ideal for redundancy, provide higher availability of services and services from different clouds. The increase in demand has led to the emergence of several varieties of cloud deployment models offering different rates of scalability, convenience, performance, privacy, and cost.
Private Clouds Advantages
With PaaS, an organization accesses a pre-defined environment for software development that can be used to build, test, and run applications. This means that developers don’t need to start from scratch when creating apps. PaaS allows the developer to focus on the creative side of software development, as opposed to tedious tasks such as writing extensive code or managing software updates or security patches. Examples of PaaS products include Google App Engine, web servers, and SQL servers.
It’s such a cost-effective and resource-positive approach that more companies should adopt it. Its infrastructure strategy facilitates application and data portability greatly and enables companies to mix and match options that best suit their requirements. Multiple companies share the bill, which lowers the individual cost.

Because of its restricted bandwidth and storage capacity, community resources often pose challenges.
Hybrid Clouds are normally short-term configurations, maybe for test and dev purposes, and can often be a transitional state for enterprises before moving a service to reside purely in the Public Cloud. This table highlights some of the differences between the Cloud types. So feel free to pause the video just to examine the contents of this table just so you really understand the differences. That brings me to the end of this lecture covering the three main deployment types of Cloud technology. For the remainder of this course, I’ll be primarily focusing on Public Cloud deployments.
For example, startups that cannot afford costly servers don’t need to wait for months to prove their viability as they can get the correct amount of compute they need to get into business quickly. We often talk about the cloud like it’s a place, but it’s actually an operating model, not a destination. It’s how organizations deliver automated, programmable and on-demand access to IT infrastructure and resources at optimal speed with minimal friction. On the basis of the former conducted business and security analysis the implementation and Migration Security Concept has to be developed. The migration starts with a realistic test scenario, which is executed by employees of the cloud customer with real applications, but mostly as a simulation and not in real service.

For large development projects, PaaS is considered a flexible platform to manage and implement instant platform productions. Complex cloud architecture can lead to difficulties in monitoring and troubleshooting systems. Requires the development and maintenance of multiple deployment and pipeline strategies. Portability is not a concern because the government might have no intention of moving its centralized applications and data. Thanks to its segmented storage, the security protocols are simpler.
It reduces the chances that a single service failure will make the entire organization go offline. This approach is designed to work with legacy systems that are unable to access the public cloud. Public clouds may appear a cheaper option, especially for startups that don’t have enough budget to purchase expensive servers. However, increasingly complex costs and pricing schemes can make it hard for companies to keep track of their IT spending.
Infrastructure as a Service (IaaS)
This can help you speed time to market, scale quickly, and gain the agility to quickly try out new applications and services. It is a one-to-one environment for single use, so there is no need to share your hardware with anyone else. The main difference between private and public cloud deployment models is how you handle the hardware. It is also referred to as “internal cloud,” which refers to the ability to access systems and services within an organization or border. How cloud computing services are implemented, hosted and accessed by users is called cloud deployment.
For large enterprises wishing to minimize costs, it is worth choosing trade-offs. The infrastructure is owned by service providers, so there is no need for users to buy and maintain their own hardware. Vendors offer resources as a service with pay-as-you-go tariffs, all working online.
Now is the time for organizations to build and expand the capabilities they wish they’d invested in before the crisis. The agility and flexibility that cloud technology enables means opening up new ways of working, operating, and doing business. The importance of cloud technology is even more apparent when we look at the performance gap that already exists between enterprise technology leaders and laggards. Leaders who invested in cloud technology as part of their digital transformation journeys have been able to adjust their supply chains and ways of buying at speed. They carry less fixed IT costs, making it possible to cut expenses far quicker than laggards who have been slow to migrate to the cloud. These laggards are now aggressively partnering to re-focus, control costs and catch up.
What is a Cloud Deployment Model?
The essential models differ in managing, owning, handling security protocols and access control specifics. Previously, only 4 deployment models of cloud computing used to be defined. Lastly, to figure out which out of the cloud computing deployment models and services that would work best for your needs, it’s important to know what your end-goal is. Some companies cannot operate solely in the public cloud because of security concerns or data protection requirements.

Summary Of The Public Cloud Deployment Model
Secondary tasks, including the analysis of development and testing workloads, can be handled using the public system. The hybrid cloud approach protects and controls strategic assets in the most cost-efficient manner. On top of that, this model simplifies and streamlines the transfer of data and applications.
Community Cloud Advantages
Normally, public cloud providers offer IaaS, PaaS or SaaS services to their customers . Businesses usually choose a public cloud as their cloud deployment model as its cost-effective, highly reliable, scalable and easy to manage. However, choosing a public cloud is not always the most secure option for sensitive data. Unlike public cloud, it provides a dedicated environment and services to a single company. A private cloud can either be hosted on-premises or at a datacenter owned and managed by a third party on behalf of the customer. As you might imagine, on-premise vs. third-party data centers have very different operational costs and responsibility models.
Hybrid Cloud Model
The only difference is that it allows access to only a specific group of users who share use cases or interests. Customers of virtual private clouds usually have access to a particular segment of the public cloud. In terms of price and features, this is a compromise between the public and private models of the clouds.
Private clouds also offer more security and compliance support than public clouds. This enables the business to reallocate IT operations costs away from hardware/software spending and from personnel expenses, towards meeting other goals. In addition, with applications hosted centrally, updates can be released without the need for users to install new software. One drawback of SaaS comes with storing the users’ data on the cloud provider’s server. Examples of applications offered as SaaS are games and productivity software like Google Docs and Word Online.
This is because it is rare that two public cloud services will experience an outage simultaneously. A private cloud is an environment specifically dedicated to a single user within the user’s firewall. It grants access to only authorized users, giving companies more central control over security factors and data.
