Public Cloud vs. Private Cloud: What’s the Difference?
A hybrid cloud is a type of cloud computing that combines on-premises infrastructure—or a private cloud—with a public cloud. Hybrid clouds allow data and apps to move between the two environments. Many organizations choose a hybrid cloud approach due to business imperatives such as meeting regulatory and data sovereignty requirements, taking full advantage of on-premises technology. Jun 28, · Unlike public cloud, private cloud deployments (as well as whatever hardware is used to store it) are maintained entirely by the user. Because private cloud deployments are managed by the user, that means the user is responsible for the security of the hardware and data stored within.

The benefits of a hybrid cloud platform
Apr 10, · Computing in which service provider makes all resources public over the internet. It only supports connectivity over the private network. It has only . Although both public and private cloud offer hosting solutions, the way they operate differs when it comes to security, performance and control. Companies who require a high level of performance, control and security should opt for a private cloud solution, whereas those who are perhaps smaller companies could consider a public cloud. Aug 03, · Traditionally, private clouds run on infrastructure owned by that organization, although services such as Amazon Virtual Private Cloud now enable customers to build private clouds using public cloud data centers. In general, public clouds and private clouds provide the .
A hybrid cloud is a type of cloud computing that combines on-premises infrastructure—or a private cloud—with a public cloud. Hybrid clouds allow data and apps to move between the two environments. Many organizations choose a hybrid cloud approach due to business imperatives such as meeting regulatory and data sovereignty requirements, taking full advantage of on-premises technology investment, or addressing low latency issues. The hybrid cloud is evolving to include edge workloads as well.
Edge computing brings the computing power of the cloud to IoT devices—closer to where the data resides. By moving workloads to the edge, devices spend less time communicating with the cloud, reducing latency, and they are even able to operate reliably in extended offline periods. A hybrid cloud platform gives organizations many advantages—such as greater flexibility, more deployment options, security, compliance, and getting more value from their existing infrastructure.
When computing and processing demand fluctuates, hybrid cloud computing gives businesses the ability to seamlessly scale up their on-premises infrastructure to the public cloud to handle any overflow—without giving third-party datacenters access to the entirety of their data.
Organizations gain the flexibility and innovation the public cloud provides by running certain workloads in the cloud while keeping highly sensitive data in their own datacenter to meet client needs or regulatory requirements. This not only allows companies to scale computing resources— it also eliminates the need to make massive capital expenditures to handle short-term spikes in demand, as well as when the business needs to free up local resources for more sensitive data or applications.
Companies will pay only for resources they temporarily use instead of having to purchase, program, and maintain additional resources and equipment that could remain idle over long periods of time. Several different cloud computing models, types, and services have evolved to meet the rapidly changing technology needs of organizations. There are three different ways to deploy cloud services: on a public cloud, private cloud, or hybrid cloud. Which deployment method depends on your business needs.
Public clouds are the most common type of cloud computing deployment. The cloud resources like servers and storage are owned and operated by a third-party cloud service provider and delivered over the internet. With a public cloud, all hardware, software, and other supporting infrastructure are owned and managed by the cloud provider. Microsoft Azure is an example of a public cloud.
Public cloud deployments are frequently used to provide web-based email, online office applications, storage, and testing and development environments. A private cloud consists of cloud computing resources used exclusively by one business or organization. But in a private cloud, the services and infrastructure are always maintained on a private network and the hardware and software are dedicated solely to your organization.
In this way, a private cloud can make it easier for an organization to customize its resources to meet specific IT requirements. Private clouds are often used by government agencies, financial institutions, any other mid- to large-size organizations with business-critical operations seeking enhanced control over their environment.
Most cloud computing services fall into four broad categories: infrastructure as a service IaaS , platform as a service PaaS , serverless, and software as a service SaaS. Browse a dictionary of common cloud computing terms.
This is the most basic category of cloud computing services. With IaaS, you rent IT infrastructure—servers and virtual machines VMs , storage, networks, and operating systems—from a cloud provider on a pay-as-you-go basis. Learn more about IaaS. Platform as a service refers to cloud computing services that supply an on-demand environment for developing, testing, delivering, and managing software applications.
PaaS is designed to make it easier for developers to quickly create web or mobile apps, without worrying about setting up or managing the underlying infrastructure of servers, storage, network, and databases needed for development.
Learn more about PaaS. Overlapping with PaaS, serverless computing focuses on building app functionality without spending time continually managing the servers and infrastructure required to do so.
The cloud provider handles the setup, capacity planning, and server management for you. Serverless architectures are highly scalable and event-driven, only using resources when a specific function or trigger occurs. Learn more about serverless computing. Software as a service is a method for delivering software applications over the Internet, on demand and typically on a subscription basis. With SaaS, cloud providers host and manage the software application and underlying infrastructure, and handle any maintenance, like software upgrades and security patching.
Users connect to the application over the Internet, usually with a web browser on their phone, tablet, or PC. Learn more about SaaS. Edge computing allows customers to run VMs, containers and data services at edge locations.
By bringing the power of cloud computing to IoT devices closer to where the data resides, companies can use machine learning and AI to unlock new business opportunities. Connecting IoT devices and systems closer to your users, the data, or both allow for real-time insights and experiences, delivered by highly responsive and contextually aware apps.

Frequently asked questions. What are examples of the hybrid cloud and public vs private clouds? Some practical examples of the hybrid cloud in action: Many customers take advantage of the hybrid cloud to achieve global scale, increased reliability, AI-enabled security, and cost savings offered by the public cloud. In highly regulated industries, data residency requirements may mandate that certain sets of data must be kept on-premises, while other workloads can reside in the public cloud.
