Key features: - Aggregate infrastructure requirements (CPU, memory, storage, network) - Three deployment profiles: Dev/Test, Staging, Production - Cloud-specific configurations for Azure AKS, AWS EKS, and on-premises - Node pool breakdown for production with specialized workload separation - Storage performance requirements with IOPS and latency specifications - Network bandwidth and latency requirements - High availability and disaster recovery guidance - Cost estimates and optimization strategies - Quick reference sizing cheat sheet Focus on CSP-level infrastructure planning without service-specific details. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- docs/HARDWARE_REQUIREMENTS.md | 129 ++++++++++++++++++++++++++++++++++ 1 file changed, 129 insertions(+) create mode 100644 docs/HARDWARE_REQUIREMENTS.md diff --git a/docs/HARDWARE_REQUIREMENTS.md b/docs/HARDWARE_REQUIREMENTS.md new file mode 100644 index 000000000..016c5c843 --- /dev/null +++ b/docs/HARDWARE_REQUIREMENTS.md @@ -0,0 +1,129 @@ +# Hardware Requirements for Bud-Stack Platform + +## Executive Summary + +Bud-Stack is a comprehensive multi-service platform for AI/ML model deployment and cluster management.
