Kata Containers \u00e9 um ambiente seguro de execu\u00e7\u00e3o (runtime) de cont\u00eaineres baseado em m\u00e1quinas virtuais leves. O funcionamento com eles \u00e9 semelhante ao de outros cont\u00eaineres, mas h\u00e1 tamb\u00e9m uma isolamento mais robusto utilizando tecnologia de virtualiza\u00e7\u00e3o de hardware. O projeto come\u00e7ou em 2017, com a comunidade hom\u00f4nima finalizando a fus\u00e3o das melhores ideias do Intel Clear Containers e do Hyper.sh RunV, ap\u00f3s o qual o trabalho continuou na suporte a diferentes arquiteturas, incluindo AMD64, ARM, e s\u00e9ries IBM p- e z. Adicionalmente, \u00e9 suportado o funcionamento dentro dos hipervisores QEMU, Firecracker, e existe integra\u00e7\u00e3o com containerd.
