The gap we close

Most Platforms Are Built. Few Are Architected.

✕
Clusters deployed with default configs, discovered to be wrong at 2am during an incident.
✕
Networking decisions made without understanding OVN internals, causing unexplainable packet loss.
✕
VM migrations to KubeVirt that skip live-migration and L2 adjacency planning entirely.
✕
Documentation that's outdated the day it's written, leaving teams to reverse-engineer their own platform.
✓
Every design starts with packet-level understanding — not vendor slideware.
✓
Architecture diagrams that map 1:1 to production OVS flows, not generic boxes.
✓
Virtualization migrations planned around real L2/L3 and live-migration requirements.
✓
Knowledge transfer built in from day one — your team operates it, not us.
What we do

Our Services

Every engagement starts with architecture. We go deep — from logical design to OVS flows and physical wire.

Why choose us

Why BitByteIntegration?

Four things that separate architecture-led consulting from generic IT services.

🧠
Architecture First
Every engagement starts with understanding your environment before any technology decisions are made.
📐
Production-Grade Designs
Solutions are designed for scalability, resilience, and day-2 operations — not just proof-of-concepts.
📊
Visual Architecture Blueprints
We use detailed diagrams and packet-flow visualizations to make complex systems easier to understand and maintain.
🎓
Knowledge Transfer
Every project includes documentation, workshops, and enablement so your teams can operate with confidence.
