Enterprise Case Study
Standardizing CI/CD at Scale Across 300+ Microservices
How Arxston replaced fragmented Jenkins pipelines with a standardized, secure AWS-native CI/CD platform capable of supporting hundreds of independently deployed services.

Client Context & Challenges
Client Context
The client operated a large-scale microservices architecture with over 300 independently deployed services supporting business-critical systems.
CI/CD pipelines evolved organically on Jenkins, resulting in fragmented pipelines, inconsistent delivery standards, and growing operational risk during releases.
Core Challenges
- Manual and inconsistent pipeline configurations
- Pipeline architecture unable to scale consistently across hundreds of services
- Weak security and compliance enforcement
- Slow onboarding and high cognitive load for developers
Why This Problem Mattered
As service count increased, CI/CD became a bottleneck rather than an enabler. Pipeline changes were slow, error-prone, and difficult to audit across teams.
This introduced systemic risk: inconsistent release behavior, uneven security enforcement, and growing friction between platform teams and service owners.
“The delivery platform itself was becoming a constraint on scale.”
Engineering Approach
From fragile pipelines to a standardized DevOps platform.
1. Pipeline Standardization
A template-driven CI/CD model was introduced to enforce consistent delivery behavior across services, with infrastructure and pipelines defined as code.
2. Configuration-Driven Customization
JSON-based interfaces enabled teams to customize pipelines without duplicating or modifying shared logic.
3. Automated, Event-Driven Execution
Pipelines executed automatically on code merge, ensuring fast, repeatable, and synchronized deployments.
4. Security as a Non-Negotiable Control
Security scanning, secrets management, and access controls were enforced as mandatory stages in every pipeline.
Standardized AWS CI/CD Platform Architecture
A centralized CI/CD platform replacing fragmented Jenkins pipelines with AWS-native workflows designed for scale, auditability, and controlled change.
CDK-based templates enforced consistency across services, while JSON configuration enabled service-level flexibility without increasing long-term maintenance overhead.
