A public cloud is owned by the cloud services provider, who is also called as a hosting provider. In this case, it could be Amazon Web Services, Microsoft Azure, or Google Cloud platform.
The organizations and users like you and I will be connecting to the cloud service through a secure network connection, typically over the Internet. With the public cloud, there is no need to provision local hardware, so you do not have to manage and update your system. Everything is running on the cloud provider’s hardware. In some cases, cloud users can save additional costs by sharing computing resources with other cloud users, and this is also called as multitenancy.
This scenario allows the cloud users to get their applications run without worrying about anything, managing, or maintaining the hardware on which it runs. Businesses can use multiple public cloud service providers depending on the scale they want to run on. The companies today that are using Microsoft Azure, Amazon Web Services, and Google platform are companies like Uber large companies like Novartis small and medium business companies as well that use the cloud to save costs and get the benefits that the cloud provider provides.
Characteristics of Public Cloud
Let’s talk about the characteristics of public cloud.
The most common examples of ownership are storage, processing power, CPU, memory, resources do not belong to your organization, that is utilizing them, but rather they are owned and operated by third parties, such as cloud service providers.
Multiple End Users
Public cloud modes may make their resources available to multiple organizations and not just your organization.
The public cloud provides access to the public. That means that the resources in the cloud provider’s location can be accessed through the Internet.
This is the most common cloud type deployment model where the cloud provider ensures the availability of your data and machines.
Users in organizations are typically connected to the public cloud over the Internet using a web browser.
The public clouds do not require deep technical knowledge to set up in your organization. You do not need a lot of resources as well. All you need is a laptop or desktop device or any small platform that will have a browser and very basic Internet connectivity and that’s all. The skills are all managed by the public cloud provider.
When we think about the term cloud, it always doesn’t mean that it’s with a third-party provider. Private clouds are owned and operated by an organization that uses the resources from that cloud. The organizations or enterprises will create their own cloud environment with their own data center. That means the resources, hardware, storage, and everything else that’s required to make a cloud is within the data center of the enterprise, and that means that employees of the organization can use a self-service provisioning portal to log into the private cloud and then create computing resources.
The organization, although always remains the owner and his entirely responsible for the operation of the services they provide. A good use case for this private cloud scenario would be when an organization’s data that they really do not want to put in the public cloud. Perhaps there could be legal reasons. For example, medical data that has to be compliant with HIPAA standards cannot be exposed publicly. Another scenario is where the government policies required a specific kinds of data to be kept in the country privately.
Characteristics of Private Cloud
In the previous video, you understood that the private cloud is owned and operated by individual enterprises.
The owner and user of the cloud services are the same if you compare it with the public cloud the owner which is a cloud user. These are two different things. Cloud users are as a cloud owner is the public cloud provider in case of a public cloud. But in the private cloud the owner is the company. And the user is also the company because everything is lying on-premise. Everything is lying inside your land.
Hardware means the hardware that you purchase from the cloud provider. Cloud providers manage, maintain all kinds of hardware.
Are private cloud operates only within one organization and cloud computing resources are used exclusively by neither a single organization nor a single business.
You can use private networks to connect the cloud provider. As we said, it is within your LAN environment and that will make it highly secure. The connection to your private cloud is not available on the public that means you cannot access those private resources in the private cloud from the public or Internet environment. You can only access it from your Intranet skills. To build your private cloud, it will require deep technical knowledge because you then have to maintain, set up, and manage your private cloud infrastructure.
