XenonStack partnered with a global leader in telecommunications software to design and manage a fully automated CI/CD pipeline on AWS, revolutionizing its application delivery process. Through detailed requirement workshops, XenonStack crafted a scalable, secure, and high-performing architecture aligned with AWS Well-Architected Framework principles.
Leveraging Amazon EKS, AWS CodePipeline, and CloudWatch, the solution automated infrastructure provisioning, code deployment, and monitoring, significantly accelerating deployment cycles and enhancing build reliability. The pipeline ensured high availability and robust security, boosting agility and competitive edge. This case study showcases XenonStack’s expertise as an AWS Managed Service Provider (MSP) in delivering a cloud-native CI/CD solution that drives operational excellence and business value for its client.
Client Context and Challenges
The customer faced significant challenges in its application delivery process due to manual, error-prone workflows and fragmented infrastructure management. These inefficiencies slowed development cycles, increased costs, and hindered scalability, necessitating a modern, automated CI/CD pipeline to support its global telecommunications operations.
Key Business Drivers
The customer’s reliance on manual CI/CD processes led to prolonged deployment cycles, with average release times exceeding 48 hours, impacting time-to-market for new features and services. Inconsistent infrastructure provisioning caused operational inefficiencies, contributing to a 20% increase in development costs annually. The lack of automated testing and monitoring resulted in a 10% build failure rate, delaying critical updates and affecting customer satisfaction.
The company needed a solution to automate its CI/CD pipeline, ensure scalability to handle variable workloads, and maintain high availability across global regions. The aim was to reduce costs, accelerate innovation, and strengthen its competitive position in the fast-paced telecommunications market by delivering reliable, high-quality software updates to clients.
Technical Requirements and Constraints
The legacy CI/CD systems lacked integration with modern cloud technologies, creating scalability and performance bottlenecks. The pipeline needed to support automated infrastructure provisioning, code deployment, and testing across development, QA, and production environments, handling thousands of builds daily with a 95% success rate. Ensuring 99.99% availability required fault-tolerant, multi-AZ deployments.
Security was paramount, with requirements for encryption, role-based access control, and compliance with GDPR and SOC 2 standards. Real-time monitoring and observability were critical to detect errors and optimize performance. XenonStack was tasked with designing a secure, scalable, and automated CI/CD pipeline on AWS that addressed these technical requirements while adhering to best practices.
