From Infrastructure Requirements to a Production-Ready AWS Environment
Cloud Infrastructure Assessment
We reviewed the technical requirements of QloApps, SuiteCRM, PHP, MySQL, media storage, customer data, seasonal booking traffic, and internal CRM activity. This assessment defined the required compute capacity, database configuration, security boundaries, monitoring, and backup policies.
Network and Availability Planning
The AWS environment was divided into public, private application, and private database tiers across two Availability Zones. Routing tables, security groups, subnets, load balancing, and controlled outbound access were configured to limit unnecessary exposure.
Compute, Database and Storage Deployment
The application environment was deployed across two r6i.2xlarge backend servers and four m6i.xlarge frontend servers running Ubuntu 24 LTS, Nginx, PHP 8.1, and Composer. RDS MySQL and four purpose-specific S3 buckets completed the core infrastructure.
Security and Observability Implementation
AWS WAF, IAM roles, Systems Manager, CloudTrail, VPC Flow Logs, CloudWatch, encryption, and backup policies were configured to support secure operations. Logging and monitoring provide visibility into infrastructure health, network activity, administrative actions, and database performance.
Cost and Scalability Optimisation
Resources were right-sized according to application requirements, while S3 lifecycle policies and a controlled NAT Gateway strategy reduced unnecessary spending. Reserved Instance recommendations were provided, and the environment was prepared for horizontal scaling, vertical upgrades, Auto Scaling, and future Amazon CloudFront integration.
