Cloud-Native Patterns

Q: What is a common misconception about Cloud-Native Patterns?

Cloud-native requires Kubernetes — it is a set of design principles; a PHP app on ECS Fargate can be fully cloud-native.

Q: Why does Cloud-Native Patterns matter?

A PHP application storing sessions on local disk cannot be horizontally scaled — cloud-native stateless design enables auto-scaling.

Q: How do I fix Cloud-Native Patterns?

PHP apps become cloud-native by: storing state externally (Redis/DB), logging to stdout, reading config from env vars, and handling SIGTERM for graceful shutdown

Also Known As

cloud native 12-factor stateless services

TL;DR

Stateless services, externalised config, health checks, graceful shutdown, and immutable infrastructure — the 12-Factor App extended for containers.

Explanation

Stateless processes (sessions in Redis, files in S3), externalised config (env vars, never baked in images), immutable infrastructure (replace not patch), disposability (fast startup <10s, graceful SIGTERM), health checks (readiness+liveness), structured logging to stdout, horizontal scaling.

Common Misconception

✗ Cloud-native requires Kubernetes — it is a set of design principles; a PHP app on ECS Fargate can be fully cloud-native.

Why It Matters

A PHP application storing sessions on local disk cannot be horizontally scaled — cloud-native stateless design enables auto-scaling.

Common Mistakes

Local file storage
Config baked into images
No graceful SIGTERM handling
Slow startup delaying auto-scaling

Code Examples

✗ Vulnerable

$_SESSION['cart'] = $data; file_put_contents('/tmp/cache',$data);

✓ Fixed

ini_set('session.save_handler','redis'); ini_set('session.save_path',getenv('REDIS_URL'));
$s3->putObject(['Bucket'=>getenv('S3_BUCKET'),'Key'=>$path,'Body'=>$data]);
