Container technology collects the codes and creates packages of it as well as its dependencies in order to assist applications to run efficiently from one computing environment to another.
Container tools assist in managing every aspect of containers by automating them.
Below discussed are some of the container orchestration tools.
12 Container Orchestration Tools
Kubernetes assists in automating the process of deploying the applications and making it easy to manage and monitor them.
It assists in overcoming the challenges of deploying these applications and reduces the downtime for these applications.
Key Features:
• Kubernetes keeps track of every node and container that is currently active.
If any of the containers or nodes are not working or facing any error, Kubernetes helps restart these nodes and containers to continue their functioning.
• Since Kubernetes keeps introducing changes to user applications, it closely monitors any changes happening to the application.
If any change in the application properties is about to harm the application, Kubernetes won’t allow such changes to be executed.
• Scaling an application means creating replicas of the applications that a user wants to run.
Within Kubernetes, a user can scale its application up and down with a simple command.

Customers use Amazon ECS for sensitive and priority applications because of its efficiency in providing security and reliability.
Since AWS Fargate acts as a server less architect for containers, it eliminates the dependency on servers and isolates the running application, thus upholding security.
Key Features:
• Amazon ECS can be used with a third-party Docker image repository.
The only thing that needs to be done here is, a user has to define the repository within his task, and the rest is taken care of by Amazon ECS, wherein it fetches specific images for specified applications.
• Within Amazon ECS, a user can define tasks with the help of JSON templates.
A user can run as many tasks as needed through a single task defined file.
This task definition includes containers being used, repositories being used, and data volumes being used.
Moreover, a user can have efficient control over its applications through such task definitions.
• A user can watch the performance of containers with the help of Amazon CloudWatch.
Alerts can be defined in CloudWatch whenever scaling has to be done to containers.
Price:
Pricing for Amazon Elastic Container Service are divided among three models
• Fargate Launch Type Model
Users are charged on the basis of Vcpu.
The charges have been set as
$0.04048 - $0.01263632 per vCPU per hour and $0.004445 - $0.00138756 per GB per hour.
• EC2 Launch Type Model
Within this model users only have to pay for the AWS resources.
No minimum fee is asked from the users under this plan.
They are charged as per their usage.
• Amazon ECS on AWS Outposts
There is no additional charge since the Amazon ECS control panel is on the cloud and the containers are dependent on Outpost EC2 and work the same as in the cloud.
