Don't let this gap widen
Why this program matters
Without expert mastery of NATS, your messaging systems risk latencies multiplied by 5, leading to a 20% loss of critical transactions per day.
Poorly configured clusters generate 40% additional downtime, costing up to 50 000€ monthly in lost revenue.
The absence of JetStream exposes you to irreversible data losses during traffic spikes, while JWT security flaws increase breach risks by 30%.
Train to avoid these pitfalls and scale confidently to millions of messages per second.
Program
Module 1NATS Clustering: High-Availability Deployment (CLI Tools, Prometheus Monitoring)
Dive into configuring multi-node NATS clusters, install and test R3 topologies using the nats CLI tool, simulate failures to validate resilience, configure Leaf Nodes to extend the network, perform practical exercises on real microservices cases, produce architecture diagrams and automated deployment scripts, while measuring latencies to optimize from day one.
Module 2JetStream and NATS Security: Persistence, Scaling (JetStream API, TLS/JWT)
Master JetStream to store and stream billions of messages, develop advanced consumers with ACK and redelivery, integrate TLS and JWT security for zero-trust environments, scale via mirroring and distributed placement, apply these concepts to a concrete Kubernetes project, generate Grafana dashboards for observability, and deploy a complete production-ready deliverable by the end of the session.
Evaluation method
- Continuous evaluation through practical exercises, interactive quizzes, and a graded final project.
Learning method
- 70% hands-on with real-world cases, 30% theory with live demos, pair workshops.

Our method
Training quality, guaranteed at every step
Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
You meet the trainer beforehand
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
- Live briefing on goals and team context.
- Veto right — we swap the trainer for free if needed.
Content tailored to your context
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
- Hands-on cases drawn from your stack and projects.
- Program co-written then validated by your team.
Continuous quality follow-up
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
- NPS, knowledge quizzes and skills self-assessment.
- Satisfaction guarantee: fully satisfied or free rework.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
