Application Deployment Using Elastic Kubernetes Service For Lexicon Group Of Institutes
About Lexicon Group of Institutes
The Lexicon Group of Institutes, founded in 2006 in Pune, India, is a leader in education. Established by Shri S. D. Sharma, the group includes preschools, high schools, a school for special students, and a post-graduate management institute.
The institutes are known for strong curriculum design and high-quality teaching. Their schools provide child-focused learning, while the Lexicon Rainbow School supports children with special needs. The management institute shapes future leaders with corporate-ready skills.
The Challenge
Lexicon wanted to deploy applications on EKS with high security and strong monitoring.
Key concerns were:
Creating an EKS cluster with best security practices.
Setting up monitoring for every EKS component.
Moving from a traditional setup to containerized applications.
Planning for future microservices deployments.
Ensuring data protection at infrastructure level.
Their applications held sensitive data, making security and scalability top priorities.
Why AWS Was Chosen
Lexicon selected Amazon Web Services for its reliability, performance, and broad service offerings.
Key AWS features used:
Networking: VPC, Security Groups, NACL, Subnets.
Databases: Amazon RDS for managed services.
Compute: Amazon EC2 instances.
High availability: Autoscaling, RDS read/write nodes.
Containerization: Amazon EKS and ECS.
Encryption: Managed KMS keys for data security.
AWS provided cost savings, faster resolution of issues, and documentation for security best practices.
Partner Solution by Teleglobal
We designed and deployed a secure and scalable EKS setup for Lexicon.
Our solution included:
EKS control plane with managed Kubernetes.
Worker nodes in an autoscaling group using Amazon Linux AMIs.
Ingress resources mapped to Application Load Balancer (ALB) for traffic handling.
Private Elastic Container Registry (ECR) for storing application images.
Route 53 for DNS routing to ALB.
Benefits of the Solution
Managed Kubernetes Cluster
Amazon EKS runs across multiple Availability Zones for high availability.
Automatic detection and replacement of unhealthy nodes.
Integrated console for cluster management and troubleshooting.
IAM for role-based access control.
VPC isolation for cluster security.
Elastic Load Balancer integration for traffic distribution.
Managed Node Groups
Simple node creation, updates, and scaling.
Nodes built on secure Amazon Linux AMIs.
Easy upgrades with managed node groups.
Strategies Applied
We followed a step-by-step approach:
Designed the architecture for scalability and availability.
Created the EKS cluster with the right Kubernetes version.
Configured Ingress with AWS ALB for routing and traffic spikes.
Stored all container images securely in Amazon ECR.
Key Architecture Components
1. EKS Control Plane
Runs Kubernetes apps on EC2 with AWS features. Integrated with IAM, VPC, and ALB for security and networking.
2. Worker Nodes (EC2)
Two t3.medium EC2 nodes were deployed in public subnets. They handled application workloads and scaled when needed.
3. Application Load Balancer (ALB)
Distributed incoming traffic across pods. Integrated with Kubernetes Ingress for traffic management.
4. Amazon Route 53
Managed DNS and routed user requests to the Application Load Balancer.
Results
The new EKS-based application deployment brought these benefits:
Strong security across infrastructure and apps.
Faster and reliable scaling during traffic surges.
Improved application performance with managed Kubernetes.
Reduced downtime with autoscaling and multi-AZ setup.
Accurate monitoring and alerting for every resource.
Conclusion
Teleglobal helped Lexicon Group of Institutes move from traditional deployment to a secure Kubernetes platform on AWS.
With Amazon EKS, they now run applications with high reliability and scalability. The architecture supports future microservices deployments, keeping their education services strong and uninterrupted.
By combining automation, monitoring, and AWS security, we delivered a system that meets Lexicon’s current needs and future growth plans.
