The document discusses container orchestration tools on AWS including Amazon ECS and Amazon EKS. It provides an overview of ECS, describing it as a fully managed container orchestration platform. It also summarizes EKS, noting that it is fully managed Kubernetes that allows users to run Kubernetes on AWS. The document compares ECS and EKS, noting differences in cost, ease of use, support, and compatibility between the two services.

• API Server: você precisa interagir com o cluster do Kubernetes? Use a API. A
API do Kubernetes é a interface do plano de controle. Ela processa
solicitações internas e externas. O servidor da API determina se uma
solicitação é válida. Se for, ela a processa. É possível acessar a API por meio
de chamadas REST, da interface de linha de comando kubectl;
• Scheduler: seu cluster está íntegro? Se você precisar de novos containers,
onde eles ficarão? Isso é um trabalho para o Scheduler. Ele analisa quais os
recursos de que um pod necessita, como CPU e memória. E também avalia
integridade do cluster. Depois, ele programa o pod no worker node apropriado.
• etcd: o etcd é um banco de dados de armazenamento de chave/valor que
contém as informações e dados de configuração sobre o estado do cluster. Ele
é distribuído, tolerante a falhas e foi projetado para ser a principal fonte de
informações sobre o cluster.
• Controller-Manager: um controlador é um loop de controle que observa o
estado compartilhado do cluster por meio do API Server e faz alterações na
tentativa de mover o estado atual para o estado desejado. Exemplos de
controladores que vêm com o Kubernetes hoje são o controlador de
replicação, controlador de endpoints, controlador de namespace e controlador
de contas de serviço.
• kubelet: faz a comunicação com o control plane. O kubelet assegura que os
containers estejam em execução em um pod. Quando o controlplane precisa
que algo aconteça em um worker node, o kubelet realiza a ação.
• kube-proxy: é um proxy que facilita os serviços de rede do Kubernetes. O
kube-proxy gerencia as comunicações de rede dentro e fora do cluster.

Amazon ECS AWS Fargate Amazon EKS
Cost
Free Amazon service Pay for the amount of
memory and vCPU used by
the containers
Fee of $0.10 per cluster per
hour, around $72 per cluster
per month
Where it runs
Only available on AWS Only available on AWS as
part of Amazon ECS
Runs based on Kubernetes
and can be migrated in and
out of AWS anytime
Ease of use
Learning curve of Amazon
ECS architecture is lower
than that of Amazon EKS
Same learning curve as
Amazon ECS, but easier to
deploy and manage
More complex to use and
deploy containers.
What it supports
Supports AWS Management
Console, to access and
manage AWS through a
simple and intuitive web user
interface (WUI)
Supports AWS Management
Console, as ECS does
Supports Kubernetes plugins
integration
Compatibility
Windows containers
compatibility
Limited compatibility with
some Amazon services (e.g.,
you can’t attach persistent
storage to Fargate)
Every configuration needs to
be done using kubectl
