System Administration & Hosting

The Columbia Group’s IT professionals develop applications that we host and administer in order to provide robust Software as a Service (SaaS) solutions that provide great value to our customers.

Containerization and Orchestration

Containerization and orchestration in the cloud can reduce costs and allow you to respond rapidly to changing requirements. TCG understands the benefits of containerization and evaluates if cloud hosting might be right for you. We scan our running containers to identify when they need to be refreshed for security patching. We can recommend security tools for continuous monitoring of your production containers.
