G&L Systemhaus, a Cologne‑based integrator with 20 years of experience powering Europe’s top live and on‑demand streams—including the European Parliament’s 24 × 7 media‑control pipeline—relies on relentless uptime and performance. 

This case study will show how Avesha helped G&L transform their infrastructure operations—cutting onboarding time from days to hours, slashing latency by 63 %, and reducing peak‑hour infrastructure spend by 38 %. By eliminating 85 % of network‑related support tickets and enabling real‑time, slice‑level chargeback, Avesha empowered G&L to scale faster, spend smarter, and gain unprecedented visibility into cost and performance. 
 

Background

To meet new audience and cost targets, G&L is re-architecting its media workloads as a hybrid Kubernetes fabric:

• On-premises ARM64 K3S clusters in Düsseldorf & Frankfurt, handle live video encoding and metadata enrichment.
• Dual Akamai Connected Cloud (Linode Kubernetes Engine) clusters host the CMS, APIs, and orchestration logic.

Success depends on secure, low-latency communication between all clusters - without re-writing applications or managing fragile VPNs

Challenges

1. Fragmented networking: ad-hoc tunnels and per-service firewall rules slowed deployments and auditing.
2. Mixed architectures: ARM64 on-prem ↔︎ x86 cloud required custom builds for every networking component.
3. Dynamic workload peaks: live events created short, unpredictable spikes; over-provisioning wasted cores the   
   rest of the week.
4. Cost visibility: finance teams lacked team-based usage data to charge back clients accurately.
5. Aggressive timeline: European Parliament go-live demanded production readiness in fewer than eight weeks.

Solution: Avesha Enterprise for KubeSlice

Implementation Steps

1. ARM64 package build: Avesha delivered a new KubeSlice bundle for G&L’s K3S servers within 48 hours.
2. Slice design workshop: Joint architects mapped “cms”, “encoder”, and “monitor” namespaces across every site.
3. Service Export / Import: enabled cross-cluster DNS without static IPs or application changes.
4. Service Gateway: gave CMS safe access to Azure-native databases still in use.
5. Progressive rollout: traffic migrated in 15 % increments; users saw zero downtime.

Results

Customer Voice

“Partnering with Avesha allows us to have our on-premises and cloud clusters securely communicate with each other. It also ensures that the same namespaces can be used in multiple environments.”   
- Alexander Leschinsky, Co-Founder & CEO, G&L Systemhaus

Conclusion

Avesha KubeSlice gave G&L a seamless hybrid cloud media fabric that:

• Unifies ARM64 and x86 clusters under one secure overlay.
• Bursts only the peaks, trimming cloud spend by nearly 40 %.
• Provides slice-level (team based) observability for accurate client charge-backs.
• Sets the stage for AI-driven predictive autoscaling with Smart Scaler.
