Infrastructure Automation Scripts

Infrastructure automation scripts move the commands run by hand on servers into files kept with your code: setting up a machine, rotating logs, taking a database dump before a change.

Commands kept in personal notes

Today they sit in a text file on a laptop or in an old chat message. They mostly work. They also drift, because each person adjusts a step slightly and nobody tells the others. Writing them down properly removes that whole category of problem.

What gets scripted

Preparing a new server

Packages, users, firewall rules, directories and permissions. The steps are applied the same way each time, so a second machine matches the first.

Routine operational jobs

Log rotation, temporary file cleanup, database exports and archive uploads are scheduled and no longer depend on memory.

Backup and restore steps

Both directions are written as scripts. Restoring under pressure is when improvised commands cause damage.

Safe, repeatable runs

Scripts are written so that running one twice does no harm. That matters when nobody is sure whether the first attempt finished.

Plain scripts or a tool

For one or two servers, shell scripts in your repository are simple and easy to read. Once several machines must stay identical, a configuration tool such as Ansible earns its place. The simpler option comes first, and the move happens only when the machine count justifies it.

FAQ

Frequently asked questions

Where do infrastructure automation scripts live?

In your own repository, beside the application or in a small operations repository. Version control is most of the benefit, since every change can then be reviewed.

Do these work on servers in our office?

Yes. On-premise machines gain the most, because they rarely have the snapshot and rebuild facilities a cloud provider offers.

Is this the same as Terraform?

No. These scripts configure a machine that already exists, while Terraform creates the machine and the network around it. Many setups use both.

Can our team run them without us?

That is the intention. Each script gets a short note saying what it does, when to run it and what to check afterwards.
