Next-Gen Server Administration & InfraOps
Immutable Infrastructure Patterns
Immutable infrastructure means servers are never patched in place. You build a new image, test it, deploy it, and retire the old one. The result is reproducible hosts, clean rollbacks, and no configuration drift hiding in production.
Ana noktalar
- Build golden images with Packer or equivalent and version them like application releases.
- Deploy by replacing instances, not by SSH-ing in to update packages.
- Keep user data and state on separate volumes or services so hosts stay disposable.
- Roll back by redeploying the previous image, not by reversing package changes.
- Automate image builds in CI triggered by base-image or dependency updates.
- Scan images for CVEs before they ship and block on critical findings.
- Use blue-green or canary deploys so bad images never take all traffic.
- Document the rebuild path so any engineer can reproduce a host from scratch.
Sık sorulan sorular
Does immutable mean no SSH ever?
Ideally yes for production. Break-glass access exists but is logged and temporary.
Is this only for containers?
No. VMs and bare-metal hosts benefit just as much from image-based deploys.
How do you handle stateful services?
State lives in managed databases or attached volumes; compute stays stateless and replaceable.
What about emergency patches?
Build a new image and roll it out fast. Patching in place breaks the model and invites drift.
