About the Customer

A public sector entity in the Oil & Gas domain wanted to deploy its Data Repository applications on a robust, scalable, and centrally managed cloud platform. With rising demands for data and increasing numbers of users requiring access, the entity partnered with Yotta to enhance its deployment infrastructure on AWS Mumbai Region.

The solution required secure application delivery, CI/CD automation, Kubernetes-based scaling, and strong administration and governance capabilities.

Challenge, Requirement & Solution offered

Customer Challenge

As the Data Repository application domain expanded, several operational and technical challenges emerged:
Legacy environments relied on unmanaged SSH access.
No unified management layer for EC2 instances, making tracking configurations and updates difficult.
Processes differed across teams, increasing risk of version drift and unstable releases.
Server-based deployments restricted application scalability.
Weaknesses in governance, encryption management, and audit processes.
Public workloads required strict filtering and routing via WAF and Route53.
These issues collectively introduced inefficiencies, instability, and operational overhead.

Customer Requirement

The entity required a solution that would:
Deliver applications securely and consistently.
Enable CI/CD automation for faster, reliable releases.
Provide Kubernetes-based scaling to handle user concurrency and data workloads.
Establish strong administration and governance with centralized visibility.
Ensure compliance with audit and regulatory requirements.

Solution Offered

Yotta implemented a cloud-native strategy on AWS VPC, leveraging Kubernetes for scalable application delivery, CI/CD automation, cloud governance, and secure operations with AWS Systems Manager.

Solution Components

  • Containerized workloads for scalability and resilience.
  • Private subnet deployments integrated with Elastic Container Registry (ECR).
  • Jenkins CI/CD pipeline for automated builds and deployments.
  • Central traffic routing with ALB + WAF + Route53.
  • EC2 instances in private subnets for auxiliary workloads.
  • PostgreSQL deployed in private subnets for secure data operations.
  • Hardened access node for administrators.
  • AWS Systems Manager enabled secure, SSH-free access, parameterized configuration, compliance verification, and visibility.
  • Centralized node access, compliance, and visibility via Systems Manager reduced operational effort.
  • WAF, Route53, IAM, KMS encryption, and SSH-free access strengthened security posture.
  • Kubernetes dynamically scaled pods to handle user concurrency and data workloads.
  • Jenkins + ECR ensured continuous, consistent image builds.
  • CloudTrail and CloudWatch provided robust logging and monitoring.

The Challenge: Quantifying the Need for Upgrade

  • Manual SSH-based administration increased risks and inefficiency.
  • Lack of automation led to unstable releases and environment drift.
  • Server-based deployments restricted scalability.
  • Governance and audit gaps created compliance risks.
  • Quantitatively, Systems Manager eliminated SSH dependency, improving efficiency by 35%, while Kubernetes autoscaling optimized resource utilization.

Solution Overview

Approach: DevSecOps-oriented design enabled consistent deployments, secure configuration management, and predictable infrastructure behavior.

Design Highlights:

  • Kubernetes Production Cluster for containerized workloads.
  • Jenkins CI/CD integrated with ECR for automated builds and deployments.
  • ALB + WAF + Route53 for secure entry, routing, and filtering.
  • EC2 instances in private subnets with hardened Jump Host.
  • PostgreSQL isolated in private subnets for secure data handling.
  • Governance enforced via Systems Manager, IAM, and CloudTrail.

Tech Components: Jenkins CI/CD, ECR, Kubernetes, EC2, PostgreSQL, ALB, WAF, Route53, CloudTrail, CloudWatch, IAM, S3, NAT Gateway, Systems Manager.

Deployment Strategy

  • Containerization of workloads.
  • Jenkins → ECR pipeline for automated artifact generation and deployment.
  • Production rollout via ALB routing.
  • Systems Manager for secure configuration baselines and compliance readiness.
