[Docs] Create "Cloud Enablement" Guide: Deployment, IaC, and Object Storage Integration

[pizofreude]

Description:

Create a comprehensive documentation page (or section) titled "NodeDB Cloud Enablement" to address the roadmap and current capabilities for deploying NodeDB on public clouds. This should clarify that while cloud-specific features are currently on the roadmap (WIP), the core architecture is already cloud-ready.

Source Context:
Discussion with CEO regarding cloud deployment roadmap and current capabilities.

Key Content to Cover:

1. Current State: The "Single Binary" Advantage

• Explain that NodeDB is currently a single static binary compiled in Rust.
• Highlight the "Zero-Dependency" deployment model:
  • No Zookeeper, no sidecars, no external dependencies.
  • Runs directly on any VM (AWS EC2, GCP Compute Engine, Azure VM, Tencent, Alibaba) or bare metal.
• Takeaway: Teams can deploy NodeDB today on standard infrastructure without complex orchestration.

2. Deployment Roadmap
Outline the planned infrastructure targets:

• Terraform Module (First Priority):
  • Official Infrastructure as Code (IaC) module for rapid provisioning.
  • Automates VM setup, networking, and initial cluster configuration.
• Kubernetes Operator:
  • For teams already invested in K8s ecosystems.
  • Provides declarative management of NodeDB clusters within a K8s cluster.

3. Storage: Object Storage Integration (L2 Cold Tier)

• Detail the plan for integrating Object Storage as the cold tier (L2) for data archiving and scaling.
• Supported Providers:
  • AWS S3
  • Google Cloud Storage (GCS)
  • Cloudflare R2
  • Aliyun OSS
  • Tencent COS
• Authentication:
  • Explain per-cloud auth support: AWS IAM, GCP Workload Identity, Alibaba RAM, Tencent CAM.

4. Architecture: Multi-Raft & High Availability

• Clarify that Kubernetes is optional, not required.
• Multi-Raft Built-in:
  • Each vShard is its own Raft group.
  • Provides built-in consensus, HA, auto-failover, and horizontal scaling.
• Deployment Flexibility:
  • Option A (Simple): A cluster of plain Terraform-provisioned VMs. NodeDB handles the rest via Multi-Raft.
  • Option B (Orchestrated): Use the future Kubernetes Operator for teams that require K8s.

Suggested Structure:

1. Overview: Why NodeDB is cloud-ready today.
2. Quick Start: Deploying the single binary on a VM.
3. Scaling Up: Introduction to Terraform and K8s (Roadmap).
4. Storage: Deep dive into Object Storage integration.
5. FAQ: "Do I need Kubernetes?" / "How does HA work?"
