Infrastructure services we manage for you
Private Cloud

Run your business applications on any device, anywhere
QuickBooks Hosting
All editions (Pro, Premier, Enterprise) on a cloud server that’s faster and more secure than your local machine.
Sage Hosting
Sage 50, 100, 300, and more, accessible from any browser with nothing to install or maintain locally.
Tax Software Hosting

We host hundreds of Windows applications: QuickBooks, Sage, Drake, Lacerte, JobBOSS, and many more. If it runs on Windows, we’ve probably hosted it.
How a move to Summit works, from first review to daily operations
Assess
A workload placement review across on-prem, VMware, and public cloud, with a cost comparison.
Move
A phased migration path, one workload at a time. Summit pilots it first and plans the rollback.
Run
Managed operations by engineers who know your environment.
Planning life after VMware?
We’ll migrate you to our Hyper-V Private Cloud for free. Your VMware VMs stay intact until each application owner signs off, so you can roll back at every step.

Why teams move their infrastructure to Summit
Summit was founded on a mission to operate IT infrastructure better than anyone, backed by engineers who fix it the first time. Here’s what you get when we run yours.

We absorb hardware, refresh, and egress costs, so the invoice is the number you told Finance it would be.

Compliance built in
SOC 2 Type II audited, with HIPAA and PCI DSS support, AES-256 encryption, DDoS mitigation, and managed security controls.

37signals’ cloud exit cut cloud spend by 60%
