Cloud computing has become an essential part of the modern business world. Over the last decade, cloud computing has evolved into a multi-faceted technology that offers businesses different options when it comes to deployment models. Public, private, and hybrid are the three types of cloud computing models available for businesses today. In this article, we will explore each type of cloud computing model in detail and discuss their advantages and disadvantages.
Public Cloud Computing: Everything You Need to Know
Public cloud computing is the most common type of cloud computing. It is a deployment model where service providers offer computing resources, including servers, storage, and applications, over the internet. Public cloud computing is usually accessed through a web browser or a mobile application.
Advantages of Public Cloud Computing
- Cost-effective: Public cloud computing is a cost-effective option for businesses that do not have the budget to invest in their own IT infrastructure.
- Scalable: Public cloud computing allows businesses to scale their computing resources quickly and easily, depending on their needs.
- Flexible: Public cloud computing offers businesses the flexibility to use as much or as little computing resources as they need, depending on their requirements.
Disadvantages of Public Cloud Computing
- Security Concerns: Public cloud computing can be vulnerable to security breaches, as the data is stored on third-party servers.
- Lack of Control: Businesses using public cloud computing do not have complete control over their data and applications, as they are stored on third-party servers.
- Limited Customization: Public cloud computing services are usually standard, and customization can be limited.
Private Cloud Computing: Everything You Need to Know
Private cloud computing is a deployment model where a business sets up its own cloud infrastructure, either on-premises or in a third-party data center. Private cloud computing is usually used by large enterprises that require a high level of security and control over their data.
Certainly, Pink Hat is the main Linux-based supplier of enterprise cloud infrastructure. It’s been adopted by 90 % of enterprises and has greater than 8M builders. Its OpenShift expertise is a key part of its success, because it gives a solution to simply deploy multi-cloud environments by a full stack management and administration functionality constructed on prime of business normal Kubernetes and deployed in a digital Linux stack.
Advantages of Private Cloud Computing
- High Security: Private cloud computing offers businesses the highest level of security, as the data is stored on their own servers.
- Complete Control: Businesses using private cloud computing have complete control over their data and applications, as they are stored on their own servers.
- Customizable: Private cloud computing services can be customized to meet the specific needs of a business.
Disadvantages of Private Cloud Computing
- Costly: Private cloud computing is more expensive than public cloud computing, as businesses have to invest in their own IT infrastructure.
- Less Flexible: Private cloud computing is less flexible than public cloud computing, as businesses have to invest in their own IT infrastructure and cannot scale as easily.
- Maintenance: Private cloud computing requires regular maintenance to ensure that the infrastructure is up-to-date and secure.
Hybrid Cloud Computing: Everything You Need to Know
Hybrid cloud computing is a deployment model that combines elements of both public and private cloud computing. Hybrid cloud computing allows businesses to use a combination of public and private cloud computing to optimize their computing resources.
“An enormous want to maneuver to the cloud, and stress from strains of enterprise to maneuver to the cloud, have created an expertise hole that has led to severe missteps and compelled IT groups to repatriate workloads that they had put within the cloud again into the information middle,” says Scott Sinclair, senior analyst at IT analysis agency ESG. “IT’s degree of competence, expertise, and training in the way to combine with the cloud is woefully insufficient.”
Advantages of Hybrid Cloud Computing
- Flexible: Hybrid cloud computing offers businesses the flexibility to use as much or as little computing resources as they need, depending on their requirements.
- Scalable: Hybrid cloud computing allows businesses to scale their computing resources quickly and easily, depending on their needs.
- Cost-effective: Hybrid cloud computing is cost-effective for businesses that require a high level of security but do not have the budget to invest in their own IT infrastructure.
Disadvantages of Hybrid Cloud Computing
- Complexity: Hybrid cloud computing can be complex to set up and maintain, as it requires integration between different cloud computing models.
- Security Concerns: Hybrid cloud computing can be vulnerable to security breaches, as the data is stored on both third-party and private servers.
- Lack of Control: Businesses using hybrid cloud computing do not have complete control over their data and applications, as they are stored on third-party servers.

Case Studies and Examples
Public Cloud Computing Case Study: Netflix
Netflix is a great example of a company that has successfully implemented public cloud computing. Netflix uses Amazon Web Services (AWS) to store, process, and deliver streaming content to over 190 countries worldwide. Netflix has been able to scale its computing resources quickly and easily to meet the demand for its services.
Automation is a key driver in Ceridian's general cloud imaginative and prescient and technique. "It is actually the muse and the basic step that is required as an entry for us to have the ability to show out our idea," says Alan Segal, Ceridian's senior vp of enterprise know-how. "It is important within the sense that we're driving towards push-button solutioning."
Automation permits groups to concentrate on significant jobs as a substitute of on routine, repetitive duties. Whereas getting crew members onboard with automation requires a while and convincing, Segal says he has encountered little opposition to the know-how. "Getting groups to actually settle for and perceive the worth and the profit...hasn't been a big problem," he says.
Automation helped Ceridian deal with modifications that the COVID-19 pandemic dropped at its operations, for instance. "The power to handle your whole operation remotely from wherever you might be, as a result of you do not have to fret about your campus, is an important step," Perlman says. Due to its automation instruments, Ceridian was in a position to transition, nearly instantly, to 100% distant operation. "There was no downtime, and no impression to our clients as a result of we ready," he says.
Private Cloud Computing Case Study: Coca-Cola
Coca-Cola is a company that has implemented private cloud computing to meet its specific needs. The company has set up its own private cloud infrastructure, allowing it to store and process large amounts of data securely while maintaining control over its applications and data. Coca-Cola’s private cloud has also helped the company to improve its business processes and increase efficiency.
Hybrid Cloud Computing Example: Dropbox
Dropbox is an example of a company that uses hybrid cloud computing. Dropbox offers file hosting services, and it uses both public and private cloud computing to store and manage data for its customers. Dropbox uses Amazon Web Services (AWS) as its public cloud provider, while using its own private cloud to store customer data. This hybrid approach has allowed Dropbox to offer its customers a high level of security while still providing the scalability and flexibility of public cloud computing.
