Open Source Architecture

Our open-source architecture leverages hardened, community-backed runtimes and frameworks to deliver flexible, vendor-neutral integration platforms.

Architecture Overview · 3 Layers
Open Source Architecture Overview
Layer 1

OSS Runtimes

Apache Camel, Kafka, and Kong Gateway provide the core logic for routing, streaming, and API management — hardened for production use.

OSS Runtimes
Layer 2

Governance & Operations

Continuous patching, CVE management, and GitOps-driven delivery ensure your open-source stack remains secure and maintainable.

Layer 3

Cloud-Native Infrastructure

Deployment on Kubernetes with full observability through Grafana and ELK, providing enterprise-grade reliability without lock-in.

Cloud-Native Infrastructure

Our open-source practice is built on a proven stack of integration, messaging, API, data, and infrastructure technologies — including Apache Camel, Kafka, ActiveMQ, Kong Gateway, Nginx, WSO2, PostgreSQL, MongoDB, Redis, Elasticsearch, Kubernetes, and Docker — all backed by end-to-end observability through Grafana and the ELK stack. We wrap this foundation with enterprise-grade services and governance to deliver production-ready platforms that give you full control without vendor lock-in.

Our Approach

Our Approach

We evaluate and select the right open-source runtimes and frameworks for your environment, then harden every deployment with continuous patching, CVE management, and vulnerability scanning. Our team handles governance across the full lifecycle — versioning, license compliance, contribution policies, and upgrade paths — so your platform stays secure and maintainable as it grows. We also build custom connectors and extensions when your integration needs go beyond what's available out of the box.

From CI/CD pipelines and GitOps-driven delivery to Terraform-managed infrastructure, we provide the implementation and operational support that gives you the flexibility of open source with the reliability your enterprise demands — typically achieving up to 60% savings over commercial licensing.

Key Capabilities

Runtime & Framework Selection

Evaluate and adopt Apache Camel, Kafka, ActiveMQ, Kong, WSO2, and other OSS runtimes matched to your integration, messaging, and API requirements.

Hardening & Security

Production hardening, CVE patching, vulnerability scanning, and security baselines for every open-source component in your stack.

Governance & Lifecycle

Version policies, upgrade paths, license compliance, and contribution controls to keep your platform secure and audit-ready.

Support & Operations

Design, deploy, and operate OSS-based platforms with CI/CD pipelines, GitOps delivery, and performance tuning.

Custom Extensions

Custom connectors, components, and integrations that extend OSS projects to fit your specific business workflows.

Containerization & Infrastructure

Kubernetes orchestration, Docker containerization, Helm Charts, Terraform-managed infrastructure, and ArgoCD-driven GitOps for repeatable, scalable deployments.

Observability & Monitoring

End-to-end visibility with Grafana dashboards, ELK stack logging, alerting, and performance analytics across your entire open-source platform.

How it Works

How it Works Diagram

1. Evaluate & Select

We start by assessing your current systems, integration requirements, and team capabilities. We then shortlist the right open-source runtimes and frameworks — such as Camel for integration flows, Kafka for event streaming, or Kong for API traffic — and validate the fit through a focused proof of concept before committing to a full build.

2. Design & Harden

Once the stack is confirmed, we architect integration patterns, data pipelines, and API layers tailored to your environment. Every component is hardened for production — with security baselines, CVE patching, vulnerability scanning, and configuration lockdowns applied before anything goes live.

3. Govern & Extend

We put governance in place so your platform stays healthy as it scales: version policies, upgrade paths, license compliance checks, and contribution controls. Where your use case demands it, we build custom connectors and extensions to bridge gaps that off-the-shelf components don't cover.

4. Operate & Deliver

Your platform is deployed through automated CI/CD pipelines with GitOps-driven delivery, Helm Charts, and Terraform-managed infrastructure. We set up end-to-end observability with Grafana and ELK so your team has full visibility from day one — resulting in up to 60% savings over commercial licensing and complete control of your roadmap.

Use Case

Scenario: A technology startup builds a cost-effective, high-performance API gateway and event mesh using Kong and Apache Kafka.

Outcome: Avoided expensive vendor lock-in, achieved sub-millisecond latency, and scaled to 10M requests per day.

Frequently Asked Questions

Yes. Technologies like Apache Camel, Kafka, and Kong power mission-critical systems at some of the largest enterprises globally. The difference is in how they're deployed. We harden every component with security baselines, CVE patching, and vulnerability scanning, then run them on Kubernetes with full observability through Grafana and ELK — so you get the same reliability you'd expect from a commercial platform.

Organizations typically see up to 60% savings on licensing alone by moving to an open-source stack. Beyond licensing, you also gain full control over scaling and your technology roadmap, which eliminates the cost of vendor-driven upgrades and per-connector fees. We help you build a total cost comparison during the evaluation phase so you can make an informed decision.

Absolutely. We support incremental migration where you run open-source and commercial platforms side by side. You can start by moving lower-risk or new integration flows to Camel or Kafka while keeping existing workloads stable, then expand at your own pace. We define the migration path, handle coexistence patterns, and ensure nothing breaks in production.

We apply continuous CVE patching, automated vulnerability scanning, and production hardening as part of every engagement. We also establish upgrade policies and version controls so your platform stays current with community security fixes. License compliance checks ensure you meet regulatory and legal requirements across all open-source dependencies.

No — and that's one of the core advantages. Everything we build uses standard, community-backed open-source projects. Your team has full access to the source code, configurations, CI/CD pipelines, and infrastructure-as-code (Terraform, Helm Charts). We transfer knowledge throughout the engagement, so you can operate independently whenever you choose.

We offer operational support that covers monitoring, alerting, incident response, performance tuning, and upgrade management. This includes maintaining your Grafana and ELK observability stack, running CI/CD pipelines, and managing Kubernetes infrastructure. Support can be structured as a managed service or as enablement where we progressively hand over operations to your team.

Our core stack includes Apache Camel, Apache Kafka, ActiveMQ, Kong Gateway, Nginx, WSO2, PostgreSQL, MongoDB, Redis, Elasticsearch, Kubernetes, Docker, Grafana, and the ELK stack. We also work with Terraform, Helm, and ArgoCD for infrastructure and delivery. If your use case calls for additional OSS tools, we evaluate and integrate them as part of the engagement.

It depends on scope, but a focused proof of concept usually takes 2–4 weeks. A full production deployment — including architecture design, hardening, governance setup, and CI/CD pipeline configuration — typically ranges from 8–16 weeks. We work in phased milestones so you see working results early and can adjust priorities as the project progresses.
