IT Services


1 +



With their previous IT landscape, OnGres was creating ad-hoc environments in orderto allow their teams to access customer environments. The main challenge was thatonboarding new customers could take weeks or even months before Virtual Private Networks (VPNs) and other security mechanisms were established and approved by customer IT teams. 

Additionally, they were unable to meet some of their customers’compliance requirements because they lacked the proper auditing mechanisms. Combined, these challenges made it difficult for OnGres to sell their service and drove up costs for their customers.

Why Tehama

OnGres originally planned to build their own secure access platform for their customers, but the resource requirements and time-to-market did not meet their standards. The team evaluated other products that had similar functionality but were more focused on the remote connectivity to customer environments, which is only one of the challenges OnGres was trying to solve. They needed comprehensive auditing and compliance capabilities, per request from their customers, and the solutions they evaluated could not meet these expectations.

The Solution

OnGres leveraged Tehama’s virtual workspaces on Amazon Web Services (AWS) to deliver their PostgreSQL Professional Services solution to their customers. With the use of Amazon Workspaces, Tehama is able to introduce a “clean room” concept with virtual workspaces. To achieve this, Tehama creates a lock between corporate networks and the workspaces, with a secure network communication channel. The onboarding process with Tehama was very thorough, with technical presentations and demos led by the Tehama team. Because of this white glove treatment, OnGres was able to roll out Tehama to their first round of customers quickly, and without impacting their day-to-day interactions. Tehama has allowed OnGres to offer their customers 24×7 reactive and proactive PostgreSQL Support, aswell as open-scoped consultancy services. 


The main advantage OnGres since implementing Tehama is the easy and timely access to customer environments. Teams no longer rely on customer-specific documentation to access each individual environment. Because of this, they spend significantly less time establishing secure connections to their customers. Previously, creating a new connection and onboarding customers would take 3-4 weeks. Now, OnGres has cut this process down to a matter of days. Further, utilizing AWS Workspaces, the Tehama virtual desktops can be configured to be instantly available, a necessary requirement to ensure that Ongres meets their SLA commitments. Ongres consultants are able to configure virtual workspaces to be instantly available as needed, minimizing the start-up time typical of a full OS stack.As typical client relationships may span several years, and multiple hardware revisions, the AWS Workspaces offer removal from hardware dependencies allowing the Ongres consultants the freedom to retain the valued virtual work environments and change the underlying hardware resources as needed. 

For OnGres, security and auditing were their biggest concerns, and Tehama’s strong auditing capabilities have been able to exceed their expectations and has helped significantly increase their customers’ satisfaction. With screen recording capabilities, customers can now request videos of what the OnGres team does through Tehama on their services, helping them troubleshoot production incidents.  

"Before Tehama, we were using ad-hoc mechanisms for our teams to access customers’ environments. The main challenge was the onboarding process took weeks and sometimes months for VPNs and other secured accesses to be established and approved by our customers’ Security Departments. And we were not able to offer our customers audit mechanisms for compliance about how we interacted with their systems. Tehama solves these problems."

Next Steps

OnGres is continuing to work with the Tehama team, providing feedback and requests for future versions, including specific provisions for PostgreSQL services that will reside within Tehama.
