The Learni story
Founded by engineers and learning experts, Learni's mission is to make high-impact tech training accessible to teams everywhere. We work remotely with organizations across the US and Canada, in your time zone, to help teams upskill fast.
Don't let this gap widen
Why this program matters
Without advanced NATS mastery, 40% of messages are lost during peak loads, as seen in 70% of non-clustered deployments (source: JetStream benchmarks).
R&D time triples to recreate persistence from scratch, downtime at 99.9% uptime instead of 99.999%, AWS costs x2 without mirroring optimization.
Architects lose 2 weeks/year debugging faulty clustering, DevOps teams face 25% urgent recalls.
Invest 14 hours to avoid 50k€/year in production losses.
Program
Module 1JetStream: Advanced Persistence and Streaming (NATS)
Dive into JetStream to durably store your messages, configure streams and consumers via nats CLI and Go API, perform exercises on selective replay and retention limits, test throughput limits on real e-commerce cases, produce deliverables like a basic monitoring dashboard, gain autonomy to scale your apps without data loss.
Module 2NATS Clustering and Security: High Availability
Set up a distributed NATS cluster with Raft consensus, practice leader election and failover on Kubernetes, integrate TLS/JWT for zero-trust authentication, simulate network failures via Docker Compose exercises, deploy leafnodes for multi-DC federation, validate with high-load IoT cases, leave with production-ready scripts and secure configs.
Evaluation method
- Interactive JetStream Quiz
- Live Cluster Case Study
- Qualiopi Certificate
Learning method
- 70% hands-on NATS labs
- Real-world microservices cases
- Post-training video support

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.
