Learning objectives

  • Configure high-availability NATS clusters
  • Implement JetStream for persistent streaming
  • Optimize distributed streaming performance
  • Secure deployments with TLS and authentication
  • Integrate NATS into microservices architectures
  • Diagnose and monitor production streams
  • Develop advanced use cases with concrete deliverables

The Learni story

Founded by passionate learning and innovation experts, Learni's mission is to make professional training accessible to everyone, anywhere in the world. Our team operates in major hubs — London, New York, Boston — and internationally, to support talents and organizations in upskilling.

Don't let this gap widen

Why this program matters

  • Without advanced NATS mastery, you expose yourself to critical message losses of up to 40% during traffic peaks, costly downtimes of 4-6 hours per incident leading to 50k€ lost revenue, impossible scaling facing growth (limited to 10k msg/s), exploitable security vulnerabilities (95% of breaches via faulty configs), and competition outpaced by JetStream-optimized teams multiplying their throughput by 5.

  • Invest now to avoid these pitfalls and boost your infrastructure by 300%.

Program

Module 1NATS Clustering: High Availability and Scaling (Docker, Kubernetes)

Dive into multi-node NATS cluster configuration, test redundancy with simulated failover exercises, deploy via Docker Compose and Kubernetes, analyze logs to identify bottlenecks, produce a production-ready resilient cluster, while mastering nats-cli tools for real-time monitoring.

Module 2JetStream Fundamentals: Persistent Storage and Consumers (Go SDK)

Discover JetStream for durable messages, create streams and consumers with the Go API, simulate message replay scenarios, optimize retention through practical exercises, generate consumption reports, integrate mirrors for replication, and validate setups with automated load tests.

Module 3Advanced Streaming: KV, Object Store and Workqueues (nats.go)

Master KV and Object stores in JetStream, implement distributed workqueues, process massive streams via pull consumers, practice on concrete cases like real-time ETL, measure latencies with Prometheus, produce scalable prototypes, and debug conflicts with integrated tools for maximum efficiency.

Module 4Security and Monitoring: TLS, JWT, Observability (Prometheus, Grafana)

Strengthen clusters with TLS, JWT and advanced ACLs, configure observability via Prometheus and Grafana, simulate attacks to test resilience, deploy custom dashboards, analyze live metrics during stress exercises, generate automated alerts, and secure streams for flawless production.

Module 5Advanced Integrations: Microservices, CI/CD and Final Project (Helm, GitHub Actions)

Integrate NATS into Kubernetes with Helm charts, automate deployments via GitHub Actions, develop a complete distributed messaging project, test under real conditions with chaos engineering, deliver a functional PoC with documentation, review best practices, and prepare for certification to excel in production.

Evaluation method

  • Daily practical quizzes, supervised final project, internal Qualiopi certification.

Learning method

  • 80% hands-on on real labs, 20% applied theory, exercises inspired by client cases.

Methods, materials and delivery

The Advanced NATS Training - Master JetStream and Clustering program is delivered onsite or remote (blended-learning, e-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 Advanced NATS Training - Master JetStream and 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.

* contact us for remote delivery feasibility** ratio varies depending on the program

Skills assessment methods

Assessment of skills acquired during the Advanced NATS Training - Master JetStream and 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 eligible for corporate training budgets and employer-funded plans.

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.

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.
