Multi-Cloud Computing Networking | On-Prem vs Cloud Computing

On-Prem :

Cloud Computing

Public Cloud

This is the most common type of Cloud. Here, the servers(data centers) are shared between multiple clients. Eg: Amazon, Google, Microsoft, many more can share the servers between them.

Private Cloud

A private cloud is operated by a single user(client), a closed group of users, or a single organization. The services and security protocols are also updated frequently. Eg: Intranet, VMware.

Hybrid Cloud

Hybrid as the name means, is a mixture of both Public and Private Cloud. You can also think of it this way, having a public cloud for storing your data accessible to the public, and a private cloud for running your production lines and legacy applications.

Data Center

Cloud Service providers use data centers to household cloud services and cloud-based resources.


Data Center is a group in the region and geographical area to provide regional service.

Availability Zones

Distinct locations within the cloud provider network that are engineered to be isolated from the failure.
if I have an Availability Zone 1A so another user may not have the same Availability Zone.

Infrastructure as a Service

You get the benefit of owning the infrastructure, physical or virtual machines for storage, creating a virtual network, and firewall. E.g. Amazon VPC.

Platform as a Service

Here you get a platform to perform your compute requests such as Operating System, Programming environment, and Database. E.g. AWS Elastic Beanstalk.

Software as a Service

You don’t need to install the application, you get “On-Demand Software”. Everything will be taken care of by the Cloud Service provider. E.g. YouTube, Office 360, and Gmail.
