😊 Welcome! This is either your first contribution to the Istio documentation repo, or
it's been a while since you've been here. A few things you should know:

  • You can learn about how we write and maintain documentation, our style guidelines,
    and the available web site features by visiting Contributing to the Docs.

  • In the next few minutes, an automatic preview of your change will be built with
    a full copy of the istio.io website. You can find this preview by clicking on
    the Details link next to the deploy/netlify entry in the status section of this
    page.

  • We care about quality, so we've put in place a number of checks to ensure our documentation
    is top-notch. We do spell checking, sanitize the Markdown, ensure all hyperlinks point to a
    valid location, and more. If your PR doesn't pass one of these checks, you'll see a red X in the
    lint_istio.io entry in the status section. Click on the Details link to get a list of the
    problems with your PR. Fix those problems and push an update; this will automatically re-run the
    tests. Hopefully this time everything will be perfect!

  • Once your changes are accepted and merged into the repository, they will initially show up
    on https://preliminary.istio.io. The changes will be published to https://istio.io
    the next time we do a major release (which typically happens every 3 months or so).
    To publish them sooner, add a cherrypick/release-x.xx label, where x.xx is the current
    release of Istio.

Thanks for contributing!

Courtesy of your friendly welcome wagon.

Mitch presented this in today's TOC, the consensus is to publish it as 2025/2026 roadmap given we are already in July 2025.

cc @istio/technical-oversight-committee @istio/steering-committee for review

lgtm

only q i have is "Multi-cluster ambient mesh will be available as an Alpha in Istio 1.27, which we plan to release in August." Is this on schedule? would it steal the thunder from the 1.17 release blog which comes up soon in Aug?

Two nits, but otherwise LGTM!

### Sidecar to ambient migration

With the promotion of Istio ambient mode to Stable, the world’s fastest service mesh is also the world’s most efficient, and is now easier to operate than ever. With graduation, we’ve seen a substantial increase in interest, and a corresponding number of requests for a comprehensive migration guide for existing sidecar users. While our previous efforts to stabilize ambient mode have been targeted at new Istio users, it is clear that the time has come to provide an onramp for our existing user base to migrate to ambient mesh. While the technical foundations for this migration have been in place for some time (and some brave users have migrated on their own), we will be making new investments in automated migration testing, tooling to assess your readiness to migrate, and documentation to guide users every step of the way.

nit: I'm sure linkerd would have something to say about "fastest". Should we reword to "most robust" or "most trusted"?

Don't know if I'm comfortable promising automated migration testing. That's a nontrivial lift
