☁️ 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.

3w ago cloud intermediate

CloudFront, Fastly, Cloudflare — caching at edge PoPs worldwide reducing latency and origin load.

2mo ago cloud intermediate

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.

2mo ago cloud intermediate

Cloud Monitoring Tools

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

2mo ago cloud intermediate

Cloud VPC & Networking

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

2mo ago cloud intermediate

Cloud-Native Patterns PHP 5.0+

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

2mo ago cloud intermediate

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.

Multi-Cloud vs Single-Cloud

Multi-cloud reduces vendor lock-in but doubles operational complexity — most lock-in comes from cloud-native services not the platform itself.

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).

Diagram: Auto Scaling

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.

2mo ago cloud intermediate

Diagram: AWS Fundamentals for PHP Developers

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.

Diagram: Cloud Computing Models

Cloud Computing Models

IaaS (infrastructure), PaaS (platform), SaaS (software), and FaaS (functions) — each level of abstraction trades control for convenience.

Diagram: Container Orchestration

Container Orchestration PHP 5.0+

Automating the deployment, scaling, networking, and health management of containers across a cluster of machines — Kubernetes is the dominant solution.

2mo ago cloud advanced

Diagram: Infrastructure as Code (IaC) Tools

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.

2mo ago cloud intermediate

Diagram: Object Storage

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.

2mo ago cloud intermediate

Diagram: Serverless Functions

Serverless Functions PHP 7.4+

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

2mo ago cloud intermediate

Diagram: Shared Responsibility Model

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.
