Observability Stack
Metrics, logs, and traces unified in a single pane. We surface the three or four signals that matter instead of a wall of dashboards no one reads.
Computer Systems Design & Integration
Systems engineered to stay upright.
Lunzun is a systems design practice. We architect, integrate, and operate the computing backbone of growing organizations — turning scattered tools, aging infrastructure, and hand-built scripts into one coherent, observable, and secure platform that scales with the business.
01 — Capabilities
Six disciplines, one integrated system.
Every engagement is staffed by senior engineers who work across the full stack of a computing environment. We do not hand off diagrams and disappear — we build, ship, and stay responsible for what runs.
01
Systems Architecture
We design the target-state architecture for your entire platform: service boundaries, data flows, security zones, and the tradeoffs that determine cost and reliability for years to come.
02
Cloud & Infrastructure
We build on AWS, GCP, and Azure with infrastructure as code. Every environment is version-controlled, reproducible, and reviewed the same way application code is reviewed.
03
Data Platforms
From ingestion pipelines to warehouses and real-time streams, we assemble the systems that turn raw operational data into decision-ready information without a brittle web of scripts.
04
Integration Services
We connect the tools your teams already use — CRM, ERP, billing, and custom software — through clean APIs and message queues that keep every record in sync and every audit trail intact.
05
Security & Compliance
We harden systems against the threats that actually matter: least-privilege access, encryption in transit and at rest, and audit logging that holds up under a real compliance review.
06
Managed Operations
We monitor, patch, and operate the platform after launch. When something breaks at 2 a.m., an engineer who knows your stack is the one who answers.
02 — Modules
Building blocks we deploy every week.
These are the concrete components our teams assemble and operate. Pick one or combine several — each is designed to plug into the others cleanly.
Identity & Access
Single sign-on, role-based permissions, and just-in-time access for the tools your workforce relies on every single day.
CI/CD Pipelines
Automated build, test, and deploy paths that let your team ship many times a day with confidence instead of once a month with dread.
Backup & Recovery
Immutable backups, tested restores, and a documented recovery runbook so that a worst-case day becomes a routine drill.
API Gateway Layer
A governed front door for your services with rate limiting, authentication, and versioning handled consistently across the board.
03 — Why Lunzun
The difference between a vendor and an owner.
Most providers sell a deliverable. We take an ownership position over the outcome. Here is how that shows up in practice.
| Dimension | Typical Vendor | Lunzun |
|---|---|---|
| Handoff | Diagram and goodbye | Build, ship, and operate |
| Documentation | Out of date in a month | Living, tested runbooks |
| Access to engineers | Account manager wall | Direct line to the builders |
| Incident response | Next business day | Around the clock, on call |
| Security posture | Checked once at launch | Continuously hardened |
| Cost visibility | Surprise invoice | Forecast before you commit |
04 — Process
From first audit to steady state.
We run a disciplined, five-phase engagement model so you always know what happens next and what it costs before we move.
Phase 01
Discover
We audit the current environment — infrastructure, applications, data, and the people who run them. The output is a clear picture of what exists, what is fragile, and what is worth keeping.
Phase 02
Architect
We design the target state and a phased migration path that keeps the business running throughout. Cost, risk, and downtime are quantified before a single resource is provisioned.
Phase 03
Engineer
We build the system in small, reviewable increments with infrastructure as code and automated tests. You can watch progress in a live environment, not a slide deck.
Phase 04
Harden
We run load tests, penetration checks, and failure drills before launch day. The system is proven to survive the failure modes we already know about.
Phase 05
Operate
We transition into steady-state operations with monitoring, patching, and a dedicated escalation path. The system stays upright, and your team stays in control.

05 — FAQ
Questions we hear most often.
Straight answers before you commit to anything.
Most discovery phases finish within two to three weeks. A full platform build usually spans eight to sixteen weeks depending on scope. We publish a milestone plan before engineering begins so you always know where the project stands.
Yes. We partner with internal teams rather than replacing them. Your engineers get access to every repository, every runbook, and every decision log. We succeed when your team can run the system without us, not when we become indispensable.
We build on Amazon Web Services, Google Cloud, and Microsoft Azure, plus on-premises and hybrid environments. The provider is a means, not a religion — we recommend whatever best fits your cost, compliance, and latency requirements.
Managed operations are priced as a flat monthly retainer based on the size and complexity of the environment, with no surprise line items. We provide a full forecast during the architecture phase so you can budget with confidence.
Yes. We have guided clients through SOC 2, HIPAA, and PCI preparation. We build the controls, logging, and evidence collection into the system from day one so an audit becomes a matter of exporting what already exists.
