Cloud terms
Infinite scale on demand — if you architect it right
Cloud computing transforms infrastructure from a capital expense into an operational one — and from a constraint into a superpower, if you use it correctly. This category covers compute, storage, networking, serverless, managed services, cost optimisation, and the architectural patterns for building systems that scale globally and fail gracefully.
Load Balancer Types — L4 vs L7
Layer-4 load balancers forward raw TCP/UDP packets based on IP and port; layer-7 load balancers terminate HTTP and route based on paths, headers and cookies — different trade-offs for different traffic.

Cloud Cost Optimisation
Systematically reducing cloud spend without reducing capability — right-sizing instances, using reserved/spot pricing, eliminating waste, and architecting for cost from the start.

Cloud Message Queues
Managed queue services — AWS SQS, Google Pub/Sub — durable scalable queuing without managing RabbitMQ infrastructure.

Cloud Monitoring Tools
CloudWatch (AWS), Cloud Monitoring (GCP), Azure Monitor — auto-collect infrastructure metrics but need explicit instrumentation for application metrics.

Cloud VPC & Networking
Virtual Private Cloud — private subnets for databases/workers, public subnets for load balancers only, security groups as stateful firewalls.

Managed Databases
Cloud-hosted database services where the provider manages patching, backups, failover, and scaling — RDS (AWS), Cloud SQL (GCP), Azure Database — trading control for operational simplicity.

PHP Deployment on Cloud Platforms PHP 5.0+
Deployment options for PHP on AWS, GCP, and Azure — EC2/VMs, containers (ECS, Cloud Run), serverless (Lambda via Bref), and PaaS (Elastic Beanstalk, App Engine).

Auto Scaling PHP 5.0+ Automatically adding or removing compute instances based on load metrics — ensuring capacity matches demand without over-provisioning or under-provisioning.

AWS Fundamentals for PHP Developers PHP 5.0+ The core AWS services a PHP developer encounters — EC2, RDS, S3, SQS, ElastiCache, and IAM — and how they map to common application components.

Infrastructure as Code (IaC) Tools Tools like Terraform, Pulumi, and AWS CDK that define cloud infrastructure in code — enabling version control, reproducibility, and automated provisioning.

Object Storage PHP 5.0+ A flat-file storage system (S3, GCS, Azure Blob) where files are stored as objects with metadata and accessed via HTTP — infinitely scalable, separate from application servers.

Serverless Functions PHP 7.4+ Event-triggered, stateless functions managed by a cloud provider — you deploy code, the provider handles servers, scaling, and availability.

Shared Responsibility Model The division of security responsibilities between the cloud provider and the customer — the provider secures the infrastructure; the customer secures what runs on it.
