Because a picture says more than 1000 words:Ī typical manual session could look like this: ssh -u teamuser -iĪs it happens, executing commands and accessing files on remote systems is a typical requirement during operations, e.g. So, as soon as you connected, you will want to escalate privileges and become the technical user. That’s the sole privilege of the technical user. You are especially not allowed to access the files that are handled by your application.

All your software runs as a technical user. Imagine you have a VM running in your company’s data center. For example, you can cover quite a distance with good old-fashioned Unix technology: sudo + ssh Using sudo over ssh for command line operations We prove it daily together with our customers. Enterprise solutions can follow KISS principles. In short: They aren’t sexy – unless you share my fetish –, but they are effective.

don’t reinvent the wheel, but build on existing generic knowledge and skills.

don’t include machine learning / blockchain / «insert other fancy buzzwords here» (we do these as well, but only when it makes sense),.

Most often, simple and powerful solutions We prefer simple solutions over complex solutions. In contrast to other consultancies, metamorphant does not focus on sepecific vendor products. Samples for the basic tools rsync and sshfs are discussed in this article, as well as configuration for advanced tools like ansible and ServerSpec.
