Al\u00e9m do Google, empresas como IBM, Red Hat, SAP e VMware tamb\u00e9m participam do desenvolvimento do Knative. O lan\u00e7amento do Knative 1.0 marcou a estabiliza\u00e7\u00e3o da API para desenvolvimento de aplicativos, a qual n\u00e3o mudar\u00e1 e manter\u00e1 a compatibilidade retroativa. O c\u00f3digo do projeto \u00e9 escrito em Go e \u00e9 distribu\u00eddo sob a licen\u00e7a Apache 2.0.      <\/p>\n<p>O modelo de desenvolvimento de aplicativos serverless proposto pelo Knative oferece um n\u00edvel adicional de abstra\u00e7\u00e3o para sistemas em nuvem, permitindo que fun\u00e7\u00f5es sejam executadas como servi\u00e7os (FaaS, Functions as a Service).

As fun\u00e7\u00f5es s\u00e3o acionadas apenas quando necess\u00e1rio e, ap\u00f3s processar o evento, podem encerrar imediatamente suas opera\u00e7\u00f5es, ou seja, ao contr\u00e1rio dos microsservi\u00e7os, n\u00e3o \u00e9 necess\u00e1rio que existam ambientes sempre ativos, consumindo recursos inutilmente.     <\/p>\n<p>A plataforma Knative inicia automaticamente cont\u00eaineres conforme necess\u00e1rio, implanta as fun\u00e7\u00f5es preparadas, organiza a gest\u00e3o e garante a escalabilidade dos ambientes necess\u00e1rios para a execu\u00e7\u00e3o dessas fun\u00e7\u00f5es. A plataforma pode ser implantada em suas pr\u00f3prias instala\u00e7\u00f5es, sem depend\u00eancia de servi\u00e7os em nuvem externos. Para execu\u00e7\u00e3o, \u00e9 necess\u00e1rio apenas o Kubernetes. Recursos s\u00e3o fornecidos para suportar diversos frameworks padr\u00e3o, incluindo Django, Ruby on Rails e Spring.

O desenvolvedor se concentra apenas na l\u00f3gica, enquanto a plataforma cuida de tudo o que diz respeito \u00e0 execu\u00e7\u00e3o. Para organizar a intera\u00e7\u00e3o de rede e o roteamento de solicita\u00e7\u00f5es, podem ser utilizadas subsistemas de rede como Ambassador, Contour, Kourier, Gloo e Istio.
