Amazon Web Services remains the most feature-rich cloud platform available, and Hellenic Technologies helps businesses in Greece and across Europe extract maximum value from it without overspending. We design AWS architectures that use the right service for each layer: EC2 and Auto Scaling Groups for stateful compute, RDS Multi-AZ for relational databases, S3 and CloudFront for object storage and content delivery, and Lambda or ECS Fargate for event-driven or containerised workloads. IAM is the backbone of AWS security. We implement least-privilege policies, enforce MFA on all human accounts, use IAM roles for service-to-service authentication, and audit permissions regularly with AWS IAM Access Analyzer. Combined with VPC security groups, NACLs, and AWS Shield Standard, the result is a hardened environment that meets enterprise security requirements. Cost optimisation is built into every AWS engagement. We right-size instances using CloudWatch metrics and AWS Cost Explorer, purchase Savings Plans or Reserved Instances for steady-state workloads, and implement S3 lifecycle rules to move cold data to Glacier automatically. Clients typically see 30–50% cost reductions versus unmanaged AWS accounts. AWS managed services we configure and operate:
  • EC2, Auto Scaling Groups, Launch Templates, and Spot Instances
  • RDS (MySQL, PostgreSQL, Aurora) with Multi-AZ and read replicas
  • S3 bucket policies, versioning, replication, and lifecycle management
  • CloudFront distributions with custom cache behaviours and Lambda@Edge
  • ALB/NLB load balancers with target group health checks
  • Route 53 DNS with health-check-based failover
  • CloudWatch alarms, dashboards, and log aggregation
  • AWS WAF with managed rule groups and rate limiting
  • Terraform-managed infrastructure with remote state in S3 + DynamoDB locking
