Platform Overview

Hubfly space is a managed cloud platform for running containerized applications, multi-service Compose stacks, stateful databases, persistent storage, private networks, and GPU workloads.

Core Operational Concepts

Hubfly space organizes infrastructure around five fundamental building blocks:

Concept	Description	Production Scope
Project	The primary operational isolation boundary. Contains containers, Compose stacks, volumes, environment variables, networks, team roles, and budget settings.	Isolate environments (e.g. `prod` vs `staging`) into separate projects.
Region	The physical cloud location where project containers and storage volumes are hosted.	Keep containers and mounted volumes in the same region for lowest latency.
Container	A managed runtime unit running a Docker image, template, Git build, or CLI upload.	Sized with explicit CPU, RAM, and ephemeral storage limits.
Managed Volume	Project-scoped persistent block storage attached to a container filesystem mount.	Outlives container restarts and redeployments.
Endpoint	A public HTTP/TCP proxy configuration with automated SSL certificates and domain routing.	Attach to public entrypoints while keeping dependencies private.

Container Tiers & Defaults

Containers run in one of two deployment tiers:

Shared Tier

Designed for free-tier testing, proof-of-concepts, staging tools, and non-critical services.

CPU: 0.3 vCPU (Shared pool)
RAM: 256 MB
Storage: 1 GB Ephemeral
Auto-Sleep: Enabled (sleeps when idle)
Price: Free (includes 360 free hours/mo)

Dedicated Tier

Designed for production web apps, APIs, databases, workers, and 24/7 mission-critical workloads.

CPU: 1.0 vCPU (Configurable scale-up)
RAM: 512 MB to 32 GB+
Storage: 4 GB+ Ephemeral / Persistent
Runtime: 24/7 Always-On, Auto-Scale option
Price: Metered resource pricing ($0.004/vCPU/hr)

Transparent Resource Pricing

Dedicated compute and persistent storage are billed hourly based on provisioned capacity:

Compute CPU: $0.004 per vCPU per hour
Compute RAM: $0.002 per GB per hour
Standard Storage: $0.00001536 per GB per hour (~$0.011/GB/mo)
Balanced Storage: 1.5x Standard multiplier (large file throughput)
High Performance Storage: 2.0x Standard multiplier (database IOPS optimization)

Persistent Storage Billing

Persistent storage volumes stay allocated regardless of whether their attached container is running, sleeping, or stopped. Delete unmounted volumes when they are no longer needed to prevent ongoing storage charges.

The billing dashboard showing account balance, projected month-end spend, and the free-tier compute burn-down — Billing tracks spend against the free tier live, and shows the zero-balance protection state the moment it applies.

Environment Variables & Scoping

Hubfly space supports both project-level environment variables (inherited by all containers in the project) and container-specific overrides.

Build Scoped: Exposed only to Hubfly space Builder during compilation (e.g. NPM_TOKEN).
Runtime Scoped: Exposed to the container at launch (e.g. DATABASE_URL).
Both Scoped: Exposed during both build time and runtime execution (e.g. NODE_ENV).
