Hexolt – DevSecOps Transformation on AWS

Customer Overview

Hexolt is a software solutions company that helps businesses build custom applications and integrate them into existing systems. The company specializes in developing apps, as well as connecting with third-party platforms like payment solutions and enterprise software.

Challenge

Hexolt faced several infrastructure and operational challenges that affected the scalability, reliability, and efficiency of the payment solution:

  • Manual Infrastructure Provisioning: Environments were set up manually, often leading to inconsistencies across development, staging, and production.
  • Infrequent Release Cycles: Monthly release cycles were prone to high deployment failure rates due to lack of automation and environment drift.
  • No Centralised Monitoring or Logging: Visibility into system health and application behavior was limited, causing delays in incident detection and response.
  • Manual Logging: Tracking system changes and access logs was done manually, increasing the risk of human error and compliance gaps.
  • Limited Scalability: The on-prem or basic hosting setup could not efficiently handle traffic spikes, impacting performance during peak usage.
  • Single Points of Failure: Lack of redundancy and failover mechanisms led to reduced application availability.
  • Security Gaps: Application and network security relied on basic firewall rules with no web-level threat protection in place.

Solution

As the technology partner, Techpartner worked closely with Hexolt to design and implement a modern, scalable, and secure AWS infrastructure using Terraform. The following solutions were delivered by Techpartner to address Hexolt’s operational and scalability challenges:

  • Infrastructure as Code with Terraform: Techpartner implemented AWS infrastructure using Terraform, enabling consistent, repeatable, and automated environment provisioning.
  • Centralized Code Management: Techpartner advised Hexolt to move all application code to a centralized Git repository, improving access control and reducing the risk of code leakage.
  • CI/CD Automation: Techpartner integrated Git with AWS CodePipeline and CodeDeploy, establishing a fully automated deployment pipeline. A blue-green deployment strategy was implemented to minimize downtime during releases.
  • Auto Scaling EC2 Deployment: Techpartner deployed the application on EC2 instances with Auto Scaling, ensuring dynamic scaling based on traffic and resource usage.
  • Application Load Balancer (ALB): Techpartner configured an ALB to distribute incoming traffic across multiple EC2 instances, enhancing availability and fault tolerance.
  • Web Application Firewall (WAF): Techpartner set up AWS WAF to protect the application from common web exploits and malicious traffic.
  • DNS Management with Route 53: Techpartner configured Amazon Route 53 for reliable DNS routing and traffic management.

3rd Party Tools Integrated

  • Grafana/Loki Techpartner integrated Grafana with Loki to provide centralized logging and dashboarding, enabling faster debugging and issue resolution.
  • Prometheus Techpartner implemented Prometheus for system and URL monitoring, providing real-time visibility into application performance.
  • Slack for deployment alerts.

DevOps Approach

Techpartner implemented a modern DevOps strategy for Hexolt, focusing on automation, security, and scalability to support continuous delivery and operational excellence:

Fully Automated Provisioning & Deployments:

  • Infrastructure provisioning and application deployments were fully automated using Terraform and AWS CodePipeline. A blue/green deployment strategy was adopted to ensure seamless updates with minimal downtime.

Shift-Left Security:

  • Security was integrated early in the development lifecycle. Techpartner enabled code scanning, policy compliance checks, and vulnerability assessments within the CI/CD pipeline to detect issues before deployment.

Auto-Scaling & Health Checks:

  • Application deployments included auto-scaling groups and integrated health checks, ensuring the environment could adapt to traffic changes and maintain availability without manual intervention.

Business & Technical Impact

  • Reduced release time from 30 days to 2 days.
  • 90% improvement in deployment success rate.
  • 100% compliance coverage through AWS Config & CloudTrail automation.
  • Cost savings of ~35% by optimizing EC2 sizing and storage.
