Cloud Concept(Basic): Types of Cloud Computing & their differences.

There are mainly four types of cloud types architecture provided by different cloud vendors based on customers demand. They are Multi-Cloud, Public, Private & Hybrid cloud. There are another types of cloud for government is called government cloud. It's portal and offerings are quite different than any other cloud offerings. I will explain it later in any future newsletter.

Multi-Cloud:

When an organizations uses multiple cloud computing services from more than one providers(vendor) to achieve flexibility, cost savings, and reduced risk is called Multi-Cloud environment or Multi-Cloud.

Example: An organization might use Oracle for data storage, AWS for development and testing, and Microsoft Azure for disaster recovery.

Public Cloud:

The public cloud refers to computing services provided by the vendors via the internet, publicly accessible to all users or purchasers. Enabling customers to pay solely for the resources they utilize, such as CPU processing power, storage, or data transmission capacity.

Example: Amazon Web Services(AWS), Microsoft Azure, IBM & Oracle cloud etc.

Private Cloud:

A private cloud called as internal or corporate cloud is the type of cloud computing dedicated to a single organization. It doesn't share any resources with other users/organizations.

Example: Amazon VPC, Oracle PCA, Huawei Virtual Private Cloud (VPC), Hewlett Packard Enterprise-GreenLake etc.

Hybrid Cloud:

Hybrid cloud refers to a mixed computing, storage, and services environment made up of on-premises infrastructure, private cloud services, and a public cloud.

Example: Amazon Web Services (AWS) or Microsoft Azure—with orchestration among the various platforms. Using a combination of public clouds, on-premises computing, and private clouds in your data center means that you have a hybrid cloud infrastructure.
