Date: November 28, 2025
TL;DR: Wave Autoscale 3.0 delivers 40% cloud cost savings, 2x faster autoscaling than HPA, and comprehensive Day 2 operations automation—all from a single platform.
🛤️ The Journey to 3.0
When we launched Wave Autoscale, we built it as a programmable autoscaling engine that could handle anything—VMs, Kubernetes, OpenStack, AWS Lambda, DynamoDB. Engineers could configure complex autoscaling policies with minimal code.
But after talking to many of customers, we heard the same message: "We need deeper Kubernetes automation, not broader platform coverage."
So we pivoted. We rebuilt Wave Autoscale as an ML-driven Kubernetes optimization platform, became an Amazon EKS Service Ready Partner (1st in APAC, 15th globally), and signed our first enterprise customer, BC Card (BC Card is a leading South Korean payment processing company).
Working with BC Card and other enterprises taught us something critical: autoscaling alone isn't enough. Teams managing 100+ workloads with limited SRE resources need automation across the entire Kubernetes operational lifecycle—not just scaling, but rightsizing, storage management, traffic control, and predictive insights.
That's why Wave Autoscale 3.0 is developed.
✨ What's New in 3.0: Complete Day 2 Operations
Version 3.0 transforms Wave Autoscale from a smart autoscaling tool into a complete Kubernetes Day 2 operations platform focused on three outcomes:
1. 💵 40% Cloud Cost Reduction
Stop over-provisioning. Eliminate waste. Optimize continuously.
2. 📊 2x Faster Autoscaling
React in seconds, not minutes. ML-driven decisions beat static thresholds.
3. 🛡️ Operational Efficiency at Scale
Automate repetitive tasks. Manage 100+ workloads with a fraction of the engineering effort.
Insights → Actions: How Wave Autoscale 3.0 Works
Most Kubernetes tools show you metrics. Wave Autoscale gives you insights that trigger automated actions.
💡 Insights: Detect Problems Before They Become Incidents
Cost Optimization
- Smart Sizing Analysis: Identify workloads requesting 4 CPU but using 0.1
- Idle Node Detection: Find nodes with only DaemonSet pods consuming resources
- Unused PV Detection: Discover orphaned storage volumes driving up costs
Performance Optimization
- Workload CPU Utilization Analysis: Classify workloads into severity bands (< 40%, 40-60%, 60-80%, ≥80%)
- Pod Scheduling Pending Delay: Detect systematic scheduling bottlenecks before they impact users
Reliability Forecasting
- Cluster Resource Forecaster: Predict CPU/memory/pod exhaustion 7-30 days ahead
- PV Capacity Forecast: Prevent storage failures before they happen
- Memory Leak Detection: Identify OOM risks before containers crash
🤖 Actions: Automate Everything After Detection
Wave Autoscale doesn't just alert you—it fixes problems automatically based on the insights it generates.
| Action | What It Does |
|---|---|
| Autopilot | ML-driven autoscaling that reacts < 10s—2x faster than HPA |
| Autopilot Scheduler | Cron-based scaling for predictable events (e.g., Black Friday) |
| Smart Sizing | Automatically adjust CPU/memory requests/limits based on actual usage |
| Min/Max Recommendation | Data-driven HPA boundary suggestions to prevent over/under-provisioning |
| PV Auto Expansion | Expand persistent volumes before capacity is reached |
| PV Auto Cleanup | Delete unused PVs after a safe retention period |
| Wave Flow (Traffic Shaping) | Priority-based traffic control using WASM in service mesh (Istio, Kong) |
| NetFUNNEL Integration | Virtual waiting room for traffic spikes that exceed infrastructure capacity |
🛠️ Operations Features: Manage at Scale
- Multi-Cluster Management: Control Wave Autoscale across N clusters from a single console
- Alert Management: Centralized alerting with context from insights
- WA Metrics Agent: Efficient metrics collection using 4x fewer resources than Prometheus
👥 Who Should Use Wave Autoscale 3.0?
1. Teams Running Large Clusters Who Want to Cut Cloud Costs
If you're spending $50K+/month on Kubernetes infrastructure and suspect you're over-provisioned, Wave Autoscale will find and eliminate 30-40% waste automatically.
2. Teams Frustrated with Basic Kubernetes Autoscaling
HPA reacts slowly. VPA can't run with HPA. Manual tuning is endless. Wave Autoscale's ML-driven Autopilot eliminates all of this—just set your objective (performance or cost) and let it learn.
3. Small Teams Managing Too Many Workloads
If you have 2-3 SREs managing 100+ microservices, Wave Autoscale automates the repetitive Day 2 operations (scaling, sizing, storage, traffic) so your team can focus on strategic work.
🏆 Real-World Impact: BC Card Case Study
BC Card (a leading South Korean payment processing company, 13M users, 5M MAU, 100K DAU) adopted Wave Autoscale to handle marketing-driven traffic spikes across 100+ workloads.
Results:
- Latency reduced from ~10s → ~1.5s during peak events
- 40% better resource utilization by eliminating unnecessary over-provisioning
- Engineering time reclaimed for strategic initiatives instead of manual HPA tuning
Roadmap: What's Next
We're continuing to expand Wave Autoscale with features driven by customer needs:
- Q4 2025: Karpenter visualization, optimization, and management
- Q1 2026: GPU observability and insights for AI/ML workloads

Take Kubernetes Operations to the Next Level
Wave Autoscale 3.0 isn't just an upgrade—it's a complete rethink of how Kubernetes Day 2 operations should work. Instead of juggling 5-10 separate tools (Prometheus, Grafana, HPA, VPA, custom scripts), you get one unified platform that detects problems and fixes them automatically.
