Bring Your Own Cloud (BYOC) • 100% Open Source

Your Data.
Your Infrastructure.
Absolute Sovereignty.

The modern enterprise is held hostage by its own growth. We end the extortion. The GAJAH Stack deploys banking-grade, self-healing PostgreSQL directly into your environment—without the proprietary licensing tax.

The Executive Dilemma

Why modern enterprises are fleeing proprietary database vendors.

Licensing isn't a cost; it's a trap. As your platform scales, legacy architectures transform your success into a financial liability.

The "Success Penalty"

Traditional vendors charge per-core. As your application grows and succeeds, your licensing bill explodes—literally punishing you for your own growth. We charge a flat fee for management, regardless of server size.

The "Black Box" Risk

Managed cloud databases (PaaS) hide the engine room. When a critical incident occurs, you are locked out of root access. With Hachico, you own the infrastructure and retain complete, unrestricted control.

The Compliance Gap

Open source is free, but it's "unsecured by default." Enterprises need audit trails. We bridge the gap by deploying a hardened, pre-configured framework that satisfies SOC2, HIPAA, and PCI-DSS on day one.

GAJAH
Proprietary Reference Architecture

The Anatomy of GAJAH.

G

Guarded

Infrastructure-level Encryption at Rest (LUKS2). Data is physically unreadable without keys, ensuring maximum defense against physical and logical breaches.

A

Automated

Immutable Infrastructure-as-Code (Ansible). Deployed systematically to eliminate manual configuration drift and human error.

J

Journaled

Immutable Audit Logs via pgAudit. Tracks every query, user action, and system event to satisfy the strictest global compliance frameworks.

A

Available

Self-Healing Cluster with Distributed Consensus. Automatic failover executed in under 30 seconds via advanced quorum logic.

H

Hardened

OS-Level Tuning (CIS Benchmarks). Integrated kernel watchdogs, strict host-based network policies, and optimized connection pooling.

Strategic Considerations.

What does "Bring Your Own Cloud" actually mean?

We deploy the GAJAH Stack directly into your AWS, Azure, or on-premises environment. You retain full data sovereignty and pay your cloud provider directly at raw compute costs. Hachico does not host your data; we maintain a secure, encrypted management tunnel to keep the system healthy, ensuring zero vendor lock-in to an external hosting platform.

What is Hachico's "Exit Strategy"?

This is our strongest differentiator. Because we build on standard open-source PostgreSQL and deploy infrastructure directly in your account, you retain complete control. If you ever decide to end our contract, you keep everything. We hand over the encryption keys and administrative credentials. Your database continues running without interruption. No migration required. Zero technical debt in leaving.

How does GAJAH compare to AWS RDS or Aurora?

AWS RDS and Aurora charge a massive managed-service premium and severely limit low-level database control. The GAJAH Stack runs on raw EC2 or on-premises compute, frequently reducing infrastructure costs by 40–60%. Furthermore, it grants your engineers access to advanced extensions, host-level observability, and kernel tuning impossible in standard RDS environments.

How do you mitigate key-person ("bus factor") risk?

Relying on a single internal DBA creates a critical single point of failure. Hachico eliminates this by combining self-healing cluster automation with dedicated, fractional database engineering oversight. We codify institutional knowledge into code (IaC) and operational practices—giving you an entire reliability team for a fraction of the cost of a single senior hire.
