Ansible automation and provisioning
Every host reproducible from code, so a rebuilt server is identical to the one it replaced.
Ansible answers one question well: if this machine died right now, could you rebuild it exactly? On most on-premise estates the honest answer is no, because the server was configured by hand by someone who has since left, and the configuration exists only in the running state of the disk.
It is agentless, which is why it fits environments where installing a daemon on every host is a procurement conversation. It talks over SSH, needs nothing pre-installed beyond Python, and works the same on your own hardware as on a cloud instance — which matters when you run both.
Ansible, specifically.
We already have hand-configured servers. Where do we start?
By codifying what exists rather than rebuilding. We audit the running configuration, write playbooks that reproduce it, and verify by provisioning a fresh host and comparing. Only then do we start improving it — you cannot safely change what you cannot recreate.
Ansible or Terraform?
Both, for different jobs. Terraform declares infrastructure that should exist; Ansible configures what is inside it. On bare metal there is often nothing for Terraform to create, so Ansible carries more of the load.
Tell us what you are building.
A short conversation is usually enough to tell whether we are the right firm for the problem. If we are not, we will say so and point you somewhere better.
