Types of IT Infrastructure

There are two main types of IT infrastructure: traditional infrastructure and cloud infrastructure.

Traditional Infrastructure

With traditional infrastructure, the components are typically owned and managed on-site by a business or organization. Data storage is a critical component of traditional infrastructure, involving the management and ownership of data storage resources. This type of IT infrastructure demands significant hardware, physical space, and power, making it more costly than cloud infrastructure. However, it offers direct control over the IT environment.

Cloud Infrastructure

Cloud infrastructure, on the other hand, allows businesses to access IT services through the internet by renting from a cloud infrastructure provider. This public cloud option offers flexibility and portability, enabling access to services from various locations. Additionally, businesses have the option to create their own private cloud for more customized solutions.

In summary, choosing between traditional and cloud infrastructure depends on a business’s specific needs, resources, and priorities. Both types offer unique advantages that can significantly impact a company’s efficiency and performance.
