On-Premises
On-Premises
Running servers and software installed within your own company's facilities, managed by your own team.
In Simple Terms
On-premises means running your systems using servers and other hardware physically located inside your own company. It's commonly used when comparing deployment models with the cloud, where you use machines hosted elsewhere over the internet. Because you set everything up yourself, you can customize the environment however you like and build a setup completely isolated from external networks. That said, it comes with real trade-offs — you need to purchase the hardware upfront, and when something breaks, your team is responsible for handling repairs.
Behind the Name
The term is "On-premises." It combines "on" (meaning located at) and "premises" (a building or site), giving it the sense of "within your own company's grounds." As cloud computing spread, this term became widely used to distinguish the traditional approach of keeping hardware on-site from cloud-based alternatives.
Take a Closer Look!
On-premises refers to the approach where a company installs IT equipment such as servers in its own facilities and operates its systems from there.
This was simply how systems were run back in the day — it was the standard approach.
As cloud computing, which lets you access systems over the internet, became widespread, the term "on-premises" emerged to distinguish this traditional model from the cloud.
The biggest advantage is having full control over your company's data and systems.
By building an environment completely isolated from external networks, you can handle highly sensitive data without it ever leaving your premises, and customize your setup in fine-grained detail to match your specific operations.
This makes on-premises a strong fit when you need tight security controls tailored to your own requirements, or when you need an environment that is fully separated from external networks.
On the flip side, there are real drawbacks.
Getting started requires a significant investment of both money and time — you need to purchase server hardware and set up a dedicated space to house it all.
Once you're up and running, you also need skilled staff on hand, because when hardware fails, your team is responsible for repairs and replacements.
Many companies use both cloud and on-premises together, leveraging the strengths of each and choosing the right approach system by system.
