Visão Geral

Curso Docker with Kubernetes. Docker e Kubernetes são nomes conhecidos no mundo do desenvolvimento e implantação de software. Docker oferece plataformas de contêineres e as duas palavras Docker e Containers quase se tornaram sinônimos ultimamente. Os contêineres revolucionaram a implantação de software por serem leves e funcionarem de maneira muito semelhante às máquinas virtuais, sem o sistema operacional para fazer o software funcionar. Eles tornaram possível construir aplicativos portáteis e seguros de forma ágil, onde as empresas conseguem economizar bastante em termos de custos e infraestrutura. Dockers usados ​​por gigantes da tecnologia como Microsoft e Google continuarão em tendência.

Embora seja fácil orquestrar vários contêineres e aplicativos de uma só vez, o desafio cresce exponencialmente quando os números chegam a centenas ou milhares. É aqui que o Kubernetes e a orquestração de contêineres entram em ação para ajudar no gerenciamento, automação e dimensionamento de aplicativos em contêineres. Embora de uma perspectiva geral o Docker e o Kubernetes pareçam semelhantes, eles operam em camadas diferentes e também podem ser usados ​​juntos. Eles podem ser considerados análogos a um aeroporto. Se os contêineres são aeronaves, o Kubernetes é o controle de tráfego aéreo.
