A public sector entity in the Oil & Gas domain needed a scalable and maintainable solution for its Inspection Management System (IMS). The objective was to simplify operations for the organization and its integration partners. With increasing workloads, regulatory requirements, and the need to modernize legacy processes, the entity partnered with Yotta to adopt a cloud-native architecture hosted in the AWS Mumbai Region.
As the IMS application expanded, several operational and technical challenges surfaced:
Reliance on SSH for server access and patching, increasing operational risk.
No unified view of server fleets across environments.
Lack of automated deployments caused UAT and Production drift.
Legacy environment unable to dynamically scale containers during peak cycles.
Absence of centralized policies for access, logging, encryption, and governance.
External workloads required strict traffic filtering and controlled ingress.
These issues slowed release cycles, reduced stability, and added operational overhead.
The entity required a solution that would:
Support multi-environment deployments (UAT & Production).
Enable container orchestration for scalability.
Provide secure CI/CD integration with GitLab.
Establish unified governance across compute, networking, and observability layers.
Ensure compliance with regulatory and audit requirements.
Yotta implemented a cloud-native, container-based solution stack on AWS VPC, leveraging Kubernetes, CI/CD automation, and secure governance.
Key Solution Elements:
Separate Kubernetes clusters for UAT and Production.
GitLab integrated with AWS CodeBuild & Amazon ECR for automated builds and deployments.
Application Load Balancer (ALB) with WAF for secure traffic routing.
Public/private subnet separation with NAT gateway and restrictive security groups.
EC2 instances supporting production-grade workloads.
PostgreSQL deployed in private subnets for isolation and security.
AWS Systems Manager for secure administration, compliance automation, and OS-level visibility.
30–40% operational improvement via automation in access, configuration, and visibility.
WAF-secured ALB, IAM-based unified access, encrypted secrets, and elimination of SSH.
Dynamic container scaling during peak inspection cycles.
CI/CD pipeline aligned UAT and Production environments.
Real-time alerting and audit trails through CloudTrail & CloudWatch.
Promotion cycles reduced from days to minutes.
Approach: Infrastructure as Code + DevSecOps strategy.
Design Highlights:
Tech Components: GitLab, CodeBuild, ECR, Kubernetes, EC2, PostgreSQL, ALB, WAF, CloudTrail, CloudWatch, IAM, S3, NAT Gateway, Systems Manager.
Identified gaps in scalability, governance, and automation.
Migrated workloads into Kubernetes clusters.
Established GitLab → CodeBuild → ECR workflows.
Implemented IAM, WAF, encryption, and CloudTrail monitoring.
Systems Manager eliminated SSH, enforced compliance baselines, and streamlined patching.
Kubernetes autoscaling and ALB routing stabilized workloads during peak cycles.
Through Yotta’s expertise and AWS-native services, the Oil & Gas entity successfully modernized its IMS application. The transformation delivered secure, scalable, and automated operations, improved compliance, and reduced costs. By adopting a cloud-native architecture, the customer achieved faster release cycles, stronger governance, and a future-ready platform capable of supporting ongoing digital transformation.
