Docker против Kubernetes. Какой из них следует использовать?

Что такое Docker?
Docker - это платформа с открытым исходным кодом, позволяющая упаковывать, распространять и запускать приложения в изолированных контейнерах. Основное внимание уделяется контейнеризации, предоставляя облегченные среды, которые инкапсулируют приложения и их зависимости.

Что такое Kubernetes?
Kubernetes, часто называемая K8s, - это платформа оркестровки контейнеров с открытым исходным кодом. Она обеспечивает основу для автоматизации развертывания, масштабирования и управления контейнерными приложениями на кластере узлов.

Чем оба варианта отличаются друг от друга?
Docker: Docker работает на уровне отдельных контейнеров на одном узле операционной системы.

При этом необходимо вручную управлять каждым узлом, а настройка сетей, политик безопасности и хранилищ для нескольких связанных контейнеров может быть сложной.

Kubernetes: Kubernetes работает на уровне кластера. Она управляет несколькими контейнерными приложениями на нескольких хостах, обеспечивая автоматизацию таких задач, как балансировка нагрузки, масштабирование и обеспечение требуемого состояния приложений.

Одним словом, Docker специализируется на контейнеризации и запуске контейнеров на отдельных узлах, а Kubernetes - на управлении и оркестровке контейнеров в масштабе кластера узлов.

Telegram, a cloud based instant messaging service has been an integral platform to communicate with individuals anywhere in the world, sending messages, sharing multimedia data, and files of any kind. However, Telegram provides a feature of scheduling messages for later which not a lot of people are aware of. Moreover, Telegram provides a feature that allows users to erase any messages which are sent or received during a one-on-one chat by both the users. There are a lot of hidden and undiscovered features offered by Telegram. Similarly, the messaging platform has launched a built-in translator that allows users to translate communications within the app in any language.
