What NSOURCE LIMITED does
NSOURCE LIMITED is a London-based boutique cloud and DevOps consulting practice, founded in 2019 as a UK private limited company (Company No. 12085218). The firm operates as a micro/small practice led by founder Oguzhan Coskun, an AWS Certified Solutions Architect with production experience spanning fintech, travel, and high-traffic consumer platforms since 2014. Core services include cloud architecture and platform engineering, infrastructure as code (Terraform, CloudFormation, CDK), CI/CD pipeline automation across GitHub Actions, GitLab, Jenkins, and Bitbucket Pipelines, Kubernetes platform engineering on AWS EKS, security and PCI-DSS compliance, FinOps cost optimization, legacy migration, observability implementation, and hands-on DevOps training. Demonstrated client outcomes include ~80% lower observability cost across 30+ EKS clusters, ~70% network cost reductions via prefix delegation, seven consecutive PCI-DSS audits with zero downtime, and absorption of 250k+ requests in under 30 minutes during an unannounced traffic surge.
The technology stack centers on AWS (EKS, Lambda, VPC, CloudHSM, DynamoDB, Bedrock, Comprehend, EventBridge, IAM, S3, CloudWatch), Kubernetes with Cilium/eBPF and Hubble, Terraform, Ansible, Prometheus, Grafana, and Python/Go. Proprietary assets include the open-source 'ubernodes' field guide for Kubernetes-native crypto-node operations, reusable Terraform module suites for event routing, KMS/encryption, managed file transfer, and zero-trust access, CDC scripts for AWS EKS prefix delegation, and Helm chart libraries for internal developer platforms. The firm holds AWS Certified Solutions Architect – Associate, AWS Partner Technical Accredited, AWS Partner Generative AI Technical Specialized, and Cisco CCNA credentials.
The business model is professional services delivered through direct, sales-led consulting engagements. Revenue is generated via quote-based pricing on custom engagements with multi-year contract durations, initiated through 30-minute Calendly consultations. The primary customer segment is fintech and regulated financial services requiring PCI-DSS rigor; secondary segments include high-traffic e-commerce and consumer platforms, hybrid/multi-cloud organizations, and engineering teams seeking training. Geographic reach is claimed globally with active engagement in the UK, US, and Turkey. Marketing is content-led, leveraging long-form Medium publishing (insights.nsource.io), GitHub open-source contributions, PeerSpot validated practitioner reviews, and conference presence at AWS re:Invent and KubeCon.

Products and services
- Cloud Architecture & Platform Engineering Design and automation of cloud platforms covering IaC, Kubernetes, CI/CD pipelines, security, and cost guardrails for production-grade infrastructure. Engaged by enterprises in fintech, e-commerce, travel, and regulated industries that need production-grade reliability on AWS.
- Infrastructure as Code (IaC) Automation of infrastructure provisioning using Terraform, CloudFormation, and CDK, with reusable module suites for event routing, KMS/encryption, managed file transfer, and zero-trust access. Used by enterprises that need estate-wide standardisation and audit-defensible infrastructure.
- CI/CD Pipeline Automation Implementation of continuous integration and delivery pipelines using GitHub Actions, GitLab, Jenkins, and Bitbucket Pipelines, with automated testing and deployment plus automated weekly Ubuntu image hardening across 50+ projects on AWS.
- Kubernetes Platform Engineering Design and operation of production Kubernetes clusters on AWS EKS with high availability, upgrades, tenant isolation, and Cilium eBPF networking for high-traffic finance and consumer workloads. Supports 30+ EKS clusters in production.
- Security & Compliance Services PCI-DSS compliance expertise with a demonstrated track record of 7 consecutive audits passed with zero downtime, identity and data-access hardening, and least-privilege implementations. Targeted at regulated financial services and other compliance-bound enterprises.
- FinOps & Cost Optimization Cost guardrails and optimisation for cloud estates, including observability cost reductions (~80% by re-architecting managed Prometheus to self-hosted across 30+ EKS clusters at the same SLA), network cost cuts (~70% via prefix delegation and pod/subnet placement), and broader affordable-scaling strategies.
- Legacy Migration Services Migration of legacy orchestration to Kubernetes, and modular AWS CodeDeploy paths for workloads unable to move to Kubernetes (e.g. post-AWS OpsWorks retirement). Used by enterprises modernising legacy estates while maintaining regulatory continuity.
- Observability Implementation Prometheus, Grafana, and CloudWatch implementations for metrics, logs, and traces, including migration from vendor-managed Prometheus to self-hosted observability at scale across 30+ EKS clusters.
- DevOps Training Hands-on training in Python, Java, and DevOps skills including pipelines, cloud primitives, and systems thinking, delivered to engineering teams seeking knowledge transfer and onboarding to internal developer platforms.
- ubernodes (Open-source Field Guide) Open-source field guide for Kubernetes-native crypto-node operations, publicly available on GitHub (github.com/oguzhancoskun/ubernodes). Used by practitioners and as a community/developer-relations asset.
Quantifiable outcome
- ~80% lower observability cost — re-architected managed Prometheus service to self-hosted across 30+ EKS clusters, same SLA
- +3 more outcomes
