Remote debugging, is debugging a piece of code by connecting the application running remotely with your environment of development. Generally, developers do this using a debugger which has support for remote debugging, and a small debug server running on a remote machine.

Debugging techniques enable us to instantly locate and identify problems in programs , also helps in determining the root cause behind any issue/bug. There are many debuggers to choose from, but often users need a debugger to run on a remote system in the cloud. Therefore, having a debugger that supports remote debugging sessions will allow users to start a remote debugger on a system and connect to it from the local computer.

Debugging different programs remotely can also save a lot of time and money, especially with a system directly connected to a complex hardware that is inaccessible.

Some clients that have SCADA systems in place are normally not available online or are very expensive, which eliminates the option of buying the hardware to debug the associated program and identify the problem. The usual method involves flying to the client's headquarters and debugging the problem locally, but that isn't the most viable option, since it costs a lot of time and money. Rather than doing that, invest the time to learn remote debugging in order to debug the program from your own office in your own country without unnecessary complications.

In simple terms, remote debugging is debugging an application that runs in a place other than your local environment. This is usually done by connecting the remotely running application with your development environment. Remote debugging is also helpful when debugging problems that occur in a production environment. The remote concept not only addresses the most prevalent challenges during debugging but also enhances collaboration among development teams.

Here are the main reasons as to why a developer may opt to perform remote debugging.

Top 5 Reasons for Remote Debugging

  • The target system does not support a local debugger. In cases where the target system is an embedded system that cannot run a local debugger, remote debugging is inevitable. The same applies when debugging part of a software that should work before the target system supports a local debugger. A remote debugger has different support requirements from a local debugger and will be effective in such scenarios where the target system doesn’t support local debugging.

  • The target system lacks the resources to support local debugging Some systems cannot run a local debugger and the target program (application being debugged) simultaneously. This usually happens when the local system has insufficient resources to support debugging.

A remote debugger server uses less memory and other resources compared to a resident debugger, making remote debugging the most viable option.

  • The source files for the application being debugged cannot be accessed from a local environment When you cannot access the source files of the target program form the host system, remote debugging may be the only viable option. The same applies when debugging an application that depends on live data. The visibility of some classes of bugs depends on the state of the live system.

If a bug cannot be reproduced without working on a live system, the remote debugging approach is the best way to look at the problem and how it occurs.

  • Local debugging sessions can interfere with applications running on the target system. Running a local debugger can interfere with running applications. When the target system is interactive, for instance, local debugging can affect window interfaces. The best way to debug applications residing on such a system would be running a remote debugger.

  • Remote debugging saves time and money There’s a possibility that the target system resides in a different physical location from that of the developer. In such a scenario, the developer may be required to travel to the client’s location to debug the problem locally.

However, this is very expensive in terms of time and money. Remote debugging would be cheaper and eliminates unnecessary complications.
