Use Solo.io’s free enhanced builds of Istio, which include ambient/sidecar interoperability and additional enterprise features.

Solo.io, one of the leading contributors to Istio, develops Istio builds that underpin Solo Enterprise for Istio and that are available for free community use. These builds include several enhancements to ambient mode.

Features

Solo builds of Istio include features beyond what the upstream releases offer. The most significant is sidecar and ambient mode interoperability, which enables zero-downtime migrations.

Additional features, such as HTTP observability in ztunnel and FIPS support, are available with a Solo Enterprise for Istio license key.

Solo builds of Istio are published to us-docker.pkg.dev/soloio-img/istio. To use them, include the following Helm settings in each installation. Follow the upgrade guide for the full steps.
