# Isvara

> Isvara is a grounded reading site and AI co-pilot for running a private cloud on VMware Cloud
> Foundation (VCF) and vSphere. It is built on a Broadcom-authored field guide and answers
> operational questions with citations to that guide and to the current Broadcom documentation.

Isvara turns the Broadcom private-cloud field guide into a reading experience plus "iO", a
consultative co-pilot. iO answers questions, cites the exact section it used, can look up the
current Broadcom documentation at techdocs.broadcom.com, and computes the guide's four-band
operations score (0-100) for measurable signals such as CPU ready time, memory and disk latency,
and dropped packets. Answers are written in British English and may quote the guide directly.

## The guide: one book, four Parts (read)
- [Executive Summary](https://isvara.io/read/exec-summary): the whole idea in one sitting, for IT leaders; what good operations looks like, SLAs, and the operations score.
- [Part 1: Concepts](https://isvara.io/read/part-1): the pillars of IT operations management, and a new paradigm that corrects decade-old "best practice" misconceptions for multi-cloud.
- [Part 2: Consumption](https://isvara.io/read/part-2): the dashboards, alerts and reports that put the concepts to work, hands-on, for each persona.
- [Part 3: Counters](https://isvara.io/read/part-3): the reference section; every vSphere performance counter across the consumer and provider realms, with the SLI thresholds and the operations score.
- [Part 4: Miscellaneous](https://isvara.io/read/part-4): supporting material; query techniques for building your own metrics and views, plus the terminology.

## Tools
- [Capacity Planner](https://isvara.io/tools/capacity-planner): model ESXi capacity, size Gold/Silver/Bronze VM classes, set a VM mix, and read planned consumption across the allocation, reservation and utilisation models.
- [Cost Calculator](https://isvara.io/tools/cost-calculator): compare public-cloud unit pricing to private sellable capacity, VMs per host, and per-class VM prices.

## Key facts iO grounds in
- Utilisation is not contention: a busy VM (high CPU or memory usage) is not the same as a slow one. Slowness shows up as contention.
- The four service-level indicator (SLI) thresholds: CPU ready time 2.5%, memory latency 1.0%, disk latency 10 ms, transmit-dropped packets 0. Crossing any one is a service-level breach.
- The operations score is a four-band 0-100 score: green is 75 or above, yellow 50 or above, orange 25 or above, red below 25.
- The guide is one book in four Parts (Concepts, Consumption, Counters, Miscellaneous), with an executive summary.

## Notes
- The guide is Broadcom's own publicly published reference (VCF Division); Isvara is the reading site and co-pilot built over it.
- The capability layer is being built as a Model Context Protocol (MCP) server (Phase 3): instruments as Tools, books as Resources, methods as Prompts.
