The Problem

Why AIDLC?

Faster delivery
Tens of dollars per feature, hours of elapsed time. Not weeks.

Built-in compliance
Every action audited. Every dollar attributed to an issue.

Institutional memory
The pipeline learns. The org's knowledge stops walking out the door.

Faster onboarding
New engineers ramp on a pipeline that already knows the codebase. 

A pipeline that improves
Each cycle's retro feeds the next cycle's configuration.

Humans stay in control
Agents propose. Humans approve. Every merge is gated.

Why AIDLC?

Observability Standard

OpenTelemetry:
Baked in, not bolted on

We instrument every migrated workload with OpenTelemetry from day one, giving you vendor-neutral traces, metrics, and logs across your entire estate.
What we wire up on every engagement

Auto-instrumentation of .NET and Java services → ADOT collector sidecars on EKS → AWS X-Ray for distributed tracing → CloudWatch for metrics and logs → custom dashboards and SLO alerting. All traces, metrics, and logs flow through a single OTel pipeline, swap backends without re-instrumenting.

VM → Container replatforming

Move off bare VMs onto EKS with proper orchestration, autoscaling, and workload isolation.

Custom metrics

Business and technical KPIs exported via OTel metrics SDK to CloudWatch and Managed Prometheus.

Structured logging

JSON-structured logs with trace correlation IDs, shipped to CloudWatch Logs Insights.

SLO alerting

Composite alarms and SLO burn-rate alerts wired from day one not as an afterthought.

Case Study

Splitting a .NET Monolith into Domain Services

Performance Increase

Cost Reduction on EC2

Situation

Epos Now's REST API was a monolithic .NET Framework API bundled into a single repository with almost 20 projects and 1 host. Its infrastructure relied heavily on flexibility and scalability, but running on Windows instance types drove up cost, and the legacy .NET Framework structure restricted the use of modern libraries.

Task

The modernization had to address five main challenges:

  • Splitting the monolith: break the .NET Framework-based monolithic application into .NET Core-based domain services, and split the code repository.
  • Performance: achieve lower response times and reduced memory and CPU usage.
  • Windows licensing cost: move to Linux instance types to cut the higher cost of Windows hosting.
  • Lack of agility: remove the legacy dependency so up-to-date libraries built only for .NET Core could be used.
  • Limited scalability: scale only the specific part of the application under load, rather than the entire application.
  • Seamless modernization: keep the same interface so the Epos Now REST API could be consumed without any client-side changes.

Action

After analyzing domains and bounded contexts, the dependencies between contexts were defined and the Strangler-Fig pattern was applied to split them one by one, based on the complexity of each pattern. Traffic was diverted at the ALB layer in a path-based manner to the split domain services.

  • Framework: the latest version of .NET Core was used for the .NET Framework modernization.
  • Container orchestration: EKS (Kubernetes) was used to reap the benefits of container orchestration.
  • Preserving the interface: nginx-ingress provided path-based routing on top of the infrastructure so existing clients kept the same interface.
  • Logging: the approach was changed from push-based to pull-based (best practice for containerized environments), using the Serilog library for structured logs.
  • Infrastructure: following an "everything is code" principle, the entire infrastructure was managed with Terraform.
  • DevOps/DevSecOps modernization: GitLab (code repository and CI/CD), Helm, Snyk, Terraform, EKS, API Gateway, Lambda, and ALB.

By the end of the project, the domain services became independently deployable and independently scalable.

Results

Kloia used .NET Core and EKS to modernize Epos Now's legacy REST API into a cloud-native architecture. By converting monolithic legacy applications from .NET Framework into .NET Core and EKS, the project unlocked the agility, scalability, and cost-savings benefits of the cloud.
