5 common mistakes when deploying apps to the cloud (and how to avoid them)
From forgotten SSL renewals to backups nobody ever tested — the mistakes that keep repeating on a first cloud deployment, and how to avoid them from day one.
Deploying an app to the cloud can feel like the moment a project becomes 'real'. But that's exactly when most first-deployment mistakes happen — not because the developers aren't skilled, but because infrastructure is its own discipline.
The first and most common mistake is neglecting environment variables: API keys and database passwords hard-coded straight into the source instead of being injected at runtime. The fix is simple — any serious deploy platform, Emilion Cloud included, lets you set encrypted environment variables separate from your code.
The second mistake is relying on manual SSL. A certificate that expires without warning can take a site down for hours. Modern deploys need SSL that renews itself automatically — not a calendar reminder to renew it by hand once a year.
A third mistake: backups that were never actually tested. Having a backup is good, but a backup you've never tried restoring is a gamble. Test a restore at least once a quarter.
The fourth is repeated manual deploys — pushing files over FTP or SSH for every small change. Git-based deploys with an automated build cut out human error and leave a full record of every change that shipped to production.
And the fifth: no monitoring. Without live logs and uptime data, you find out the site is down when a customer calls. A dashboard with CPU, memory and uptime metrics isn't a luxury — it's a baseline.
