Tech Support Corner: Running / Maintaining Cogent DataHub as a Service

10 min read

Great job! You managed to configure Cogent DataHub® to fit your needs, and now you are ready to run it in a production environment, but you are left with one question – “How in the world do I run DataHub as a service?”.

Running applications as Windows services has multiple benefits but, perhaps, the most beneficial reason to run an application as a service is the ability to let the application/process run in the background without the need for a user to be logged on the operating system. For that reason, this might be why you are looking at how to run it as a service, whether you are tunneling, logging, aggregating, historizing data, and/or using Datahub as a Gateway.

Continuing our Tech Support Corner blog series, if you find yourself in this situation like other users over years, do not worry. This post will walk you through the process of running DataHub as a service as well as how to access its properties from a local and/or remote machine.

If you've seen our other, more detailed posts (specifically our Exploring OPC UA post and the DataHub OPC UA video how-to) on getting Cogent DataHub working with OPC UA clients and servers, you are probably already familiar with configuring Cogent DataHub for secure access from an OPC UA client. However, we are commonly asked how to quickly get the DataHub OPC UA server interface ready for an OPC UA client to securely connect for accessing data from the variety of other interfaces that DataHub supports.

Continuing our Tech Support Corner blog series, this short post covers just the basics for setting up the Cogent DataHub OPC UA server interface to use the highest level of security and to require a client to specify a username and password for authentication.

IoT, IIoT, MQTT, Connectivity of Things, Big Data, The Cloud - by now, you've heard these terms in some way, shape or form.  Perhaps you're working on a project requiring you to push and/or pull important process or business data to/from a cloud solution. Big data analytics applications ranging from predictive maintenance to "smart" manufacturing, amongst many other use cases, are becoming more and more common.

And Google© is a household name both in the private and professional world. Chances are, you got here using Google – whether through a Google search, or by using Google Chrome (or both). But did you know that Google has their own cloud solution called Google Cloud IoT Core©? Amongst many other things, Google Cloud IoT Core acts as an MQTT broker for storing and sharing important data in a secure cloud along with artificial intelligence and analytics and many other IoT services.

But how do you go from your data sources to Google Cloud IoT Core? In this second post in a series about connecting DataHub to IoT solutions (if you missed our first post on connecting to Amazon AWS IOT Core©, click here), we'll step through how you can configure Google Cloud IoT Core and connect it to your process and business data sources using the Cogent DataHub IoT Gateway©.
