Challenge

UST Global expected a rise in incoming traf�c and wanted to secure themselves from the risk of outages and lags in performance that result in loss of business and brand value. The ask here was to design a reliable, scalable, secure, high-performance infrastructure that enables elastic scale out and scale down to match IT costs in real-time as customer traf�c �uctuates. Dense peak periods and wild swings in traf�c patterns result in low utilization.

Solution The high-level architecture diagrams below provide an overview of the solution:

AWS Region

Upgraded to a robust, yet simple,compliant infrastructure, hosted on an AWS cloud architecture.

Elastic-Load Balancing and Auto- Scaling, helped UTS distribute traf�c among multiple Amazon-Elastic-Compute Cloud (EC2) instances across Availability Zones (AZs).

Amazon Virtual Private Cloud (Web and DB application instances were hosted inside secured VPC (Virtual private cloud) private subnets and security groups.)

NAT Gateway (grants internet access to Amazon ec2 instances in Private Subnets.)

Amazon VPC subnets (public, private (data, web) in all the Availability Zones (AZs) selected.

Routing tables for public subnets - routing through IGW

Routing tables for private subnets - routing through NAT Gateway

Auto Scaling Group (launching 4 instances) - to dynamically adjust warning and critical threshold values when the permitted throughput value changes (it auto terminates by setting ASG desired count to 0)

Amazon CloudWatch alarms to monitor Amazon EFS burst credit balance

Amazon Elastic Load Balancing (Amazon ELB) Application Load Balancer (ALB) (used to distribute the web track workloads to multiple instances deployed on Multi-AZ)

Web Auto Scaling Group (launching 4 instances) - in private subnets (web)
