  2. Technology Standards advanced

    An organisation has grown from 200 to 2,000 engineers and each team chose its own queue, cache and database. What criteria decide which technologies become paved-road defaults, which are tolerated, and which are retired — and how is the migration funded?

  3. Technology Standards advanced

    On 9 December 2021 a remote code execution flaw in Apache Log4j 2 (CVE-2021-44228, CVSS 10.0) was disclosed. Organisations that had standardised on one logging library across hundreds of services found the following week expensive in a specific way. What failed, which design decision made it possible, and what is the general lesson about standards?

  4. Technology Standards advanced

    Salesforce's multi-tenant design - described in its 2009 SIGMOD paper - stores customer-specific structures as metadata over shared tables rather than giving each tenant its own schema. What does that platform-wide constraint buy the vendor and what does it charge its customers?
