In that time, cloud-native has become the default for all new applications, and technologies like Kubernetes are widespread. Best-practices for software have evolved, and we believe that Twelve-Factor also needs to evolve — this time with you, the community.

Originally, the Twelve-Factor manifesto focused on building deployable applications without thinking about deployment, and while its core concepts are still remarkably relevant, the examples are another story. Industry practices have evolved considerably and many of the...

Heroku is joining the CNCF at the platinum level, upgrading the long-held CNCF Salesforce membership. This marks my third time serving on the CNCF board for different companies, and I’m excited to participate again. Joining the CNCF at the Platinum level signifies a major commitment, reflecting Heroku’s dedication to the evolving landscape.
