Performance Improvement
Reduction in Security Vulnerabilities
Availability
The customer’s existing AWS environment in the Mumbai region faced limited scalability, inconsistent performance, and operational complexity. Self-hosted databases required significant maintenance effort, the application architecture lacked centralized traffic management and fault tolerance, and fragmented security controls made compliance and continuous monitoring difficult.
• Designed a dedicated VPC with segmented public and private subnets, ensuring clear separation of application layers.
• Configured Network ACLs and security groups to provide least-privilege access and protect workload components.
• Deployed payment application server in public subnet with strict security controls for external communication.
• Hosted remaining application components in private subnets to enhance security and isolate internal workloads.
• Implemented granular security group policies to manage inbound and outbound traffic with only necessary ports accessible.
• Selected right-sized Amazon EC2 instances based on workload characteristics for optimal performance and cost efficiency.
• Optimized Amazon RDS instances using tailored parameter groups to improve database responsiveness and throughput.
• Designed scalable architecture enabling seamless scaling of compute and database resources as demand increases.
Delivered 30-40% faster response times, 99.9% availability, 50% reduction in security vulnerabilities, 40% less administrative overhead, and zero-downtime auto scaling through optimized Amazon EC2, Amazon RDS migration, and comprehensive security architecture.
