Hosting web application is like driving a car. every car has different fuel consumption, maintenance cost, and others. so if you want to build low footprint of the web application resources this article is for you.
🐘 PHP (Official Image: php:apache or php:7.x-fpm)
Base Image: php:7.x-apache or php:7.x-fpm (Debian Slim).
Size: ~70–150 MB depending on variant.
Minimum Host Spec:
CPU: 1 vCPU
RAM: 512 MB (1 GB recommended for frameworks like Laravel)
Storage: 100 MB+ for base image, more with extensions.
Notes: Use php:7.x-fpm-alpine for smallest footprint (~30 MB).
⚙️ ASP.NET Core (mcr.microsoft.com/dotnet/aspnet)
Base Image: mcr.microsoft.com/dotnet/aspnet: (runtime only) or dotnet/sdk (development).
Size: Runtime ~100 MB; SDK ~200–300 MB.
Minimum Host Spec:
CPU: 1 vCPU
RAM: 1 GB minimum (2 GB recommended for production).
Storage: 200 MB+ depending on SDK/runtime.
Notes: ASP.NET Core apps are heavier than PHP/Node; avoid SDK images in production.
🌐 Node.js (node:alpine)
Base Image: node:alpine (Alpine Linux).
Size: ~5–10 MB base + Node runtime.
Minimum Host Spec:
CPU: 1 vCPU
RAM: 512 MB minimum (1 GB recommended).
Storage: 50 MB+ for base image.
Notes: Ideal for microservices; very lightweight compared to ASP.NET.
🐍 Python (python:3-slim or python:3-alpine)
Base Image: python:3-slim (Debian Slim) or python:3-alpine.
Size: ~25–50 MB.
Minimum Host Spec:
CPU: 1 vCPU
RAM: 512 MB minimum (1 GB recommended for Django/Flask).
Storage: 50 MB+ for base image.
Notes: python:3-alpine is smallest but may require manual installation of build tools for some packages.
Conclusion:
Lightest stacks: Node.js (node:alpine) and Python (python:3-alpine).
Heaviest stack: ASP.NET Core (dotnet/aspnet) due to runtime requirements.
Balanced option: PHP (php:7.x-fpm-alpine) with moderate footprint.
