Cloud computing essentially involves delivering IT services, such as software, infrastructure, and storage, over the Internet. This model eliminates the need for on-premises data centers, reducing upfront costs and maintenance efforts.

Cloud computing is typically categorized into three primary models:

• Infrastructure as a Service cloud (IaaS): Provides virtualized computing resources, including servers, storage, and networking.
• Platform as a Service (PaaS): Offers a development and deployment platform for building applications without managing the underlying infrastructure.
• Software as a Service products (SaaS): Delivers software applications over the internet, eliminating the need for local installation.  

While cloud computing offers numerous benefits, it's essential to acknowledge potential challenges. Security, vendor lock-in, and data management are common concerns that businesses must address when adopting cloud solutions.

 

Public vs. Private Cloud

The cloud offers a world of possibilities for businesses - public private and hybrid cloud. However, with options like public and private clouds, where do you start?

Public clouds are shared resources hosted online by third-party providers like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP). Think of them as shared office spaces: multiple tenants, and shared resources, but with your workspace.

Private clouds are exclusive to a single organization. There are quite a few advantages of private cloud. It's like having your private office building. You control the entire infrastructure, from hardware to software.

Understanding these foundational models is crucial before diving into multi-cloud and hybrid-cloud strategies.

 

What is Multi-Cloud?

 

Multi-cloud refers to the use of multiple public cloud platforms from different providers, such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).
