The client had used old and outdated hardware to run legacy applications, all these applications were majorly lottery, post lottery, and material testing, etc. Since the applications were very old, they were consuming a high amount of resources from old and outdated hardware. Due to this the client had been facing frequent high utilization, server hang, breakdown issues very often during the lottery draw and during this time the website did not work which led to many escalations from the end users who had booked their houses. This was raised as a major concern by them.
Application and server slowness had been day-to -day operational challenges; for hosting their application and database, they needed a platform with high availability, on-demand, and scalability. Failure of the Oracle RAC management hardware under high-volume queries was a frequently reported problem. Due to the load balancer's inability to keep up with many requests, the user experience was suffering. To meet peak demands, they required the best possible use of the IT infrastructure and resources. Their systems needed to be standardized and scalable so that they could plan a faster implementation cycle, and a stable technological environment. Data security and encryption were requested, but it was challenging to accomplish this due to the old and ransomware-infected environment. The IT department had to deal with expenses related to administration, procurement, service provider management, technical support, etc.
Using CloudEndure, the environment was migrated to AWS EC2 instances using a Microsoft Oracle DB Server database. Using a firewall, several individuals connecting from various locations were remotely managed (Fortinet). Log-shipping in an AWS multi- AZ environment enabled Oracle Server to operate with high availability. CloudWatch served as the setup's monitoring tool. AWS- managed keys are used to encrypt data that is at rest. IAM had been used to grant administrators access to pertinent EC2 and S3 buckets. We built the client’s infrastructure using the AWS ap-south-1 (Mumbai) region. We established one VPC in the Mumbai area (logical data center). There are public subnets and private subnets within that VPC.
We set up security tools like the FortiGate NGFW on public subnets before placing our actual application servers and database servers behind that firewall in the private subnet. We utilized an internal application load balancer to distribute application traffic to several application servers together with AWS EC2. Additionally, there is an internet-facing AWS Network load balancer in front of the firewall. Aside from AWS EC2, ELB also uses AWS IAM to provide users with specific permissions, AWS S3 to store object-based data, AWS CloudWatch to monitor and alarm, and CloudTrail to audit AWS account logs. For WAF, DDOS, and CDN, we employed Cloudflare in addition to AWS for increased security.
