Deciding between on‑prem and cloud infrastructure is basically the IT version of choosing between buying a house or renting an apartment. One gives you total control… and total responsibility when something breaks at 2 a.m. The other gives you flexibility, convenience, and rules you didn’t write (but still have to follow).
Jacob breaks this whole on‑prem vs. cloud debate down in the video below – what each option actually means, why people get surprisingly intense about it, and how to choose what makes sense for your business without spiraling into analysis paralysis.

The Difference Between On-Prem and Cloud Infrastructure
- On‑prem (on-premises): Hardware/software you own and typically manage with your IT team or your MSP. Think servers in your building or a data center you control.
- Cloud: Infrastructure or apps you subscribe to and access over the internet, managed by a third party like Microsoft Azure, AWS, or Google Cloud. You don’t own the hardware; you pay for what you use.
Think: owning the house (on‑prem) vs. renting the apartment (cloud). If the furnace dies in your house, that’s your fun little project. If it dies in the apartment? Maintenance gets the joy of dealing with it.
Upfront Costs vs. Ongoing Costs
On‑prem usually means a big upfront purchase – servers, storage, warranties. In finance terms, that’s CapEx. It’s like paying cash for a car: pricey at first, but it’s yours.
Cloud flips that. You pay monthly for what you use – OpEx. More like leasing a car: predictable, flexible, and someone else handles the nitty gritty stuff.
Control, Compliance, and Data Residency
Some organizations simply need control. If you’re in healthcare, finance, legal, or any highly regulated field, you may need to know:
- Where exactly your data is stored
- Who has ever touched it
- How it’s protected
- Whether you can prove all of that to an auditor at 8am on a Tuesday
On‑prem makes those conversations easy: everything’s in your environment.
Cloud can still be compliant – you just have to read the fine print. Some services let you pick the region your data lives in; others may use telemetry or anonymized data for analytics.

Cloud’s Kryptonite: Your Internet Connection
Cloud tools are amazing… until your internet goes out.
If your phone system, email, files, and apps live in the cloud, a single outage can turn your office into a silent retreat. Meditative for some, catastrophic for others!
On‑prem doesn’t have this problem. Even with no internet, your local apps and file shares keep working inside your building.
Not good or bad – just different. If you go cloud‑heavy, you’ll want redundant internet connections.
The Cloud Superpower: Scale
If your business has busy seasons – tax firms, accounting teams, seasonal retail, event companies – cloud scaling is a dream.
If you need three employees in September but thirty in March, cloud services let you scale up for busy seasons and back down later so you only pay for what you use.
Try doing that with on‑prem hardware. (Spoiler: you can’t. You have to size for the maximum, and then it sits there quietly doing nothing 9 months of the year.)
Redundancy & Disaster Recovery, But Without the Drama
On‑prem redundancy means something like:
“We need a backup server… in another building… in another city… with all the same hardware… just in case.”
Cloud redundancy, on the other hand, is:
“Click this box if you want an extra copy in another region.”
Cloud DR is simply easier for most businesses, whether you need local redundancy, regional protection, or global failover.
One Isn’t Better Than the Other
Cloud isn’t magic. On‑prem isn’t outdated. Each one shines in different situations:
On‑prem might make more sense if:
- You’re heavily regulated
- You need full control
- Your internet is shaky
- You already have a strong internal IT team
Cloud might make more sense if:
- You want agility
- You have seasonal spikes in workload
- You want less hardware to maintain
- Your team works from multiple locations
And for a lot of people, the answer is both!
Hybrid is extremely normal. Think: collaboration tools (Teams, SharePoint, email) in the cloud; a line‑of‑business app or sensitive database kept on‑prem.
Understanding Management in Each Model
Here’s the simple way to think about the cloud spectrum:
- On‑prem: you manage everything, from the server rack down to app settings.
- IaaS (Infrastructure as a Service): you manage the operating system and apps; the provider handles the hardware.
- PaaS (Platform as a Service): you manage just the app and data.
- SaaS (Microsoft 365, for example): you manage the settings and users; everything else is handled for you.
It’s basically a sliding scale of “How much do you want to be responsible for?”
What Should You Do?
Start by answering a few simple questions:
- What are your compliance requirements?
- How reliable is your internet?
- Do you have seasonal spikes in workload?
- Do you need systems to run even when offline?
- Do you prefer predictable monthly costs or controlled capital expenses?
- Do you have in‑house IT capacity, or do you lean on an MSP?
All the answers to these questions help you move in the direction that suits your business best.
