Replaced All Internal Web Servers with NGINX


Device Technologies began life in the 1990’s as an orthopedic joint replacement manufacturer and designer. Over the ensuing years, the company has become a leader in medical technologies, from being the first company to distribute robotic, remote surgery tools in New Zealand, to building the world’s first complete artificial heart implant.


Keith Strachan, Solutions Architect at Device Technologies, sums up the problem at Device Technologies succinctly. “We’ve had a few issues around aging technologies disappearing from vendors, such as Microsoft Threat Management Gateway. And trying to find a suitable replacement that would actually fit both at a security level but also at a functionality level, some of the MS products they created to replace TMG with don’t do the whole portfolio of applications we desired. We looked to the market to see what else could provide reverse proxying capabilities,” said Strachan.


Strachan said that finding NGINX was easy due to the well known and documented capabilities of its reverse proxying features. “Obviously, NGINX is quite famed for Reverse Proxying. Upon quickly having a few test cases around the NGINX portfolios to see what it could do for our environment, we’ve pretty much leveraged it to replace all of our reverse proxying situations for external services for the greater business, and also some services that weren’t feasible in the past around the SAP and Citrix platforms,” said Strachan.

That means the team was not only able to replace the now end-of-lifed Microsoft Threat Management Gateway, but they were also able to do things that platform could not, such as reliably and securely route outside traffic to internal SAP systems.

We chose NGINX because there were metrics we could actually see. But also the configuration was simple, it wasn’t complicated We didn’t need to be brain scientists to understand what needed to be done in order to create those proxy scenarios.

With NGINX in place, the Device Technologies team was able to better identify problems via the NGINX logging capabilities. “The logging scenarios in relation to trying to find faults were a lot simpler to diagnose because they have a standardized format, and obviously being able to pull those into general tools such as Splunk were great. It made it a lot easier for us to get all those issues we were having, identified and sorted out quite nicely,” said Strachan.

Strachan said that NGINX has been so successful in its reverse proxy duties that the team has begun to roll it out as a Web server throughout the company. “We have recently been leveraging NGINX for the reverse proxy capabilities, but we’ve also decided to use the NGINX Web server platform as our platform of choice. ALl of our corporate Websites around the world will be replatformed onto NGINX to be the next generation of our Websites,” said Strachan.
