Joel Varty, president of Agility CMS, discusses the evolving landscape of Jamstack architecture in anticipation of his presentation at GatsbyConf. He emphasizes that Jamstack is more than just a frontend solution, offering robust capabilities for building full-stack web applications, which traditionally require significant server resources. Varty highlights the rapid adoption of Jamstack across various business levels and draws parallels between Jamstack and Cloud Native architecture, noting how Jamstack brings the value of APIs directly to users. He also discusses the importance of selecting a headless CMS that enhances user, developer, and editor experiences, advocating for a "try before you buy" approach to choosing the right platform. Additionally, Varty notes the shift from the term "JAMstack" to "Jamstack" and encourages participation in GatsbyConf, which features speakers, workshops, and engaging events like a competitive Super Mario Bros speed run.
