Why this program matters

  • Without advanced NATS mastery, 70% of messaging clusters crash under 10k msg/s, causing 2-4h daily downtime and 50k€ losses per incident according to Gartner.

  • Your microservices will saturate, data will be lost on failed failover, and security audits will fail with 40% breaches through faulty configs.

  • Competitors scale 10x better while you stagnate on legacy queues.

  • Invest 35h to avoid 100k€ annually in ops and boost performance 300%.

NATS Advanced training objectives

  • Configure resilient multi-node NATS clusters
  • Implement JetStream for persistent storage and replication
  • Secure streams with TLS, JWT, and multi-tenancy
  • Optimize horizontal scaling and advanced monitoring
  • Develop scalable event-driven microservices
  • Diagnose and resolve production failures
  • Integrate NATS with Kubernetes and observability tools

NATS Advanced curriculum: 5 modules over 5 days

Module 1 : NATS Clustering: Multi-Node Deployment (NATS CLI, Docker, Advanced Configs)

Dive into setting up resilient clusters, configure gateways and leafnodes with NATS CLI, simulate distributed topologies with Docker Compose, test automatic discovery and failover, produce resilience diagrams and validate high availability through practical exercises, gain confidence for production-ready deployments.

Module 2 : JetStream: Persistence and Advanced Streams (KV, Objects, Mirroring)

Master JetStream for durable streaming, create mirror and source streams with the NATS API, implement KV and Objects stores for distributed caching, handle pull/push consumers in real IoT cases, generate deliverables like lag dashboards, experience the power of synchronous/asynchronous replication for critical apps.

Module 3 : NATS Security: TLS/JWT Auth, Multi-Tenant ACL (NKeys, Operators)

Strengthen your deployments with bidirectional TLS and JWT operators, configure granular ACLs via NKeys, simulate attacks and intrusions on clusters, develop multi-tenant policies for SaaS, test audit logging, produce secure configs ready for production, protect your streams like a pro.

Module 4 : Scaling and Monitoring: Super Clusters, Prometheus (Metrics, Tracing)

Scale infinitely with Super Clusters and load balancing, integrate Prometheus/Grafana for custom metrics, trace with Jaeger via NATS tracing, optimize under 1M msg/s loads, analyze bottlenecks live, create custom alerts and dashboards, turn your systems into 24/7 observed performance beasts.

NATS Advanced training: access and practical arrangements

The Training NATS Advanced - Master JetStream and Scalable Clustering program is delivered onsite or remote (blended-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.

The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.

Equipment required

For the smooth delivery of the Training NATS Advanced - Master JetStream and Scalable Clustering program, the following equipment is required:

  • Mac or PC computers, high-speed fiber internet, whiteboard or flipchart, projector or interactive touch screen (for remote sessions)
  • Training environments installed on workstations or accessible online
  • Course materials, hands-on exercises and complementary resources
  • Post-training access to materials and educational resources

For intra-company training on a site outside Learni, the client commits to providing all required teaching materials (computers, internet, etc.) for the smooth delivery of the program in line with the prerequisites in the communicated program.

Skills assessment methods

Assessment of skills acquired during the Training NATS Advanced - Master JetStream and Scalable Clustering program is performed through:

  • During training: case studies, hands-on labs and professional scenarios
  • End of training: self-assessment questionnaire and skills evaluation by the trainer
  • After training: completion certificate detailing acquired skills

Program accessibility

Learni is committed to making its programs accessible. All our programs are accessible to people with disabilities. Our teams are available to adapt the pedagogical methods to your specific needs. Please contact us for any adjustment request.

Enrollment terms and lead times

Registration is possible up to 48 business hours before the start of training. All our programs are built for corporate L&D budgets and delivered onsite or remotely.

Our method

How Learni guarantees the quality of your NATS Advanced training

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.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

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.
Step 3

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.
Step 4

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.
