# Server Key Features

## 1. Overview
The hosting environment for Sekaya is engineered to provide secure, performant, and resilient operation. This document enumerates the core server-side features and operational capabilities enabling reliability, compliance, and growth scalability.

## 2. Performance & Scalability
| Feature | Description | Benefit |
|---------|-------------|---------|
| Horizontal Auto Scaling | Application & worker containers scale based on CPU, memory, queue depth | Maintains responsiveness under variable load |
| Optimized PHP Runtime | Opcache, tuned FPM process manager (dynamic/spare servers) | Reduced latency, efficient resource usage |
| Asynchronous Queue Processing | Workload offloaded to Redis queues | Smooth user experience; throughput isolation |
| Lazy & Eager Loading Discipline | ORM optimization guidelines enforced | Prevents N+1 queries, stable API/table performance |
| Config & Route Caching | Precompiled framework metadata | Faster bootstrapping in production |

## 3. Security & Compliance
| Feature | Description | Benefit |
|---------|-------------|---------|
| Role-Based Access Control | Spatie Permissions with granular prefixes | Fine-grained authorization, least privilege |
| Encrypted Storage | RDS & S3 encryption at rest (KMS/AES-256) | Data confidentiality & compliance alignment |
| TLS Everywhere | Enforced HTTPS + HSTS headers | Secure data in transit |
| Audit Logs | Activitylog for model changes | Traceability & accountable operations |
| Secure Media Access | Signed URLs / permission-checked retrieval | Controlled file distribution |

## 4. Reliability & Resilience
| Feature | Description | Benefit |
|---------|-------------|---------|
| Retryable Queue Jobs | Automatic retry with exponential backoff | Reduces transient failure impact |
| Transactional Integrity | Critical writes inside DB transactions | Consistent state; prevents partial writes |

## 5. Observability & Monitoring
| Feature | Description | Benefit |
|---------|-------------|---------|
| Structured Application Logging | Centralized JSON/structured logs | Faster troubleshooting & correlation |
| Error Aggregation | Sentry integration for stack traces & performance hints | Proactive defect resolution |
| Activity Timeline | Domain-level activity logs | Business audit & behavioral insights |
| Alerting | Threshold-based alarms (CPU, latency, queue backlog) | Rapid incident detection |

## 6. Data Management & Integrity
| Feature | Description | Benefit |
|---------|-------------|---------|
| Automated Backups | Daily RDS snapshots + retention policy | Rapid recovery capability |
| Point-in-Time Restore | RDS transaction log retention | Granular recovery from logical errors |
| S3 Lifecycle Policies | Transition to infrequent access / archival | Cost efficiency for aging content |
| Consistent Schema Migrations | Version-controlled incremental changes | Predictable evolution of data model |
| Data Validation Layer | FormRequests + service-level rules | Prevents corrupt/incomplete records |

## 10. Extensibility & Future Readiness
| Feature | Description | Benefit |
|---------|-------------|---------|
| Modular Service Layer | Clear service boundaries | Easier feature addition & testing |
| Event-Driven Hooks | Domain events trigger listeners | Decoupled secondary processing |
| API Resource Layer (Expandable) | Versioned external API capability | Partner integrations & ecosystem growth |
| Observability Hooks | OpenTelemetry integration path | Future distributed tracing |

## 11. Governance & Operational Discipline
| Feature | Description | Benefit |
|---------|-------------|---------|
| Change Management | PR reviews + CI validation | Reduced production defects |
| Security Patch Cadence | Scheduled library & base image updates | Lower exposure window |
| Policy Enforcement | Linting, tests, permission checks | Consistent code & access hygiene |
| Access Auditing | IAM & application logs reviewed | Compliance & accountability |
