Disaster Recovery

Recovery architecture across multiple data centers, with out-of-region standby and a formal separation between backup and archive.

Also known as DR, Business Continuity, RTO/RPO

Left to right is time. Each row is one of the 14 disciplines this one worked alongside, ordered so kindred disciplines sit next to each other rather than alphabetically — a landscape only means anything if neighboring rows belong together. Height is the work running in that domain in that year, weighted by what failure would have cost — life-safety ×3, a statutory obligation ×2.2, the estate itself ×1.5, an evaluation ×1. Every project declares which of those it was, so each ridge traces to an entry you can open and disagree with. Only the work that used this technology is counted, so what shows here is the company it kept rather than the record around it. Height and color are on the record-wide scale rather than this page’s own, so a modest estate draws a modest landscape and any two of these pages can be read against each other.

Architected disaster recovery across multiple data centers, with a formal backup and retention policy separating backup from archive, and evaluation of AWS, Azure and alternative hosting models against recovery objectives and the cost of meeting them.

The Cecil disaster recovery data center was designed as a facility as well as a network: dual UPS, A and B power paths, diverse carrier entry, and high-availability firewall and IPS pairs with hardware bypass.
