Hello.
After you create a task definition, you can start the task within your cluster.
https://docs.aws.amazon.com/AmazonECS/latest/developerguide/standalone-task-create.html
Additionally, by creating an ECS service, you can set up AutoScaling to scale automatically.
https://docs.aws.amazon.com/AmazonECS/latest/developerguide/getting-started-fargate.html#create-linux-service

InternalError: failed to create container model: failed to normalize image reference "https://hub.docker.com/repository/docker/digitalsplendid/rajeev". Launch a new task to retry.
The task is now successfully created but error while deploying.

This is the error message getting while trying to connect cluster with task as part of service: There was an error deploying cs50financeservice Resource handler returned message: "Error occurred during operation 'ECS Deployment Circuit Breaker was triggered'." (RequestToken: 18117225-53b0-3189-70ff-8c3df0ff98e4, HandlerErrorCode: GeneralServiceException)

First, check if you can start it as a single task without connecting to a service. https://docs.aws.amazon.com/AmazonECS/latest/developerguide/standalone-task-create.html
Judging from the error message, it seems that the DockerHub image specification in the task definition is incorrect. To pull a container image from DockerHub's private registry, you will need authentication settings as described in the AWS blog below. https://aws.amazon.com/jp/blogs/containers/authenticating-with-docker-hub-for-aws-container-services/
Also, you should be able to specify the image by specifying the URL as shown below. I don't think "https://" etc. at the beginning is necessary.
Have you checked the container logs? If you configure logging, you will be able to check the container logs. https://docs.aws.amazon.com/prescriptive-guidance/latest/implementing-logging-monitoring-cloudwatch/ec2-fargate-logs.html
Also, is the subnet you are using with ECS a private subnet? In the case of a private subnet, if you do not set up a NAT Gateway etc., you will not be able to access DockerHub and startup will fail. https://docs.aws.amazon.com/AmazonECS/latest/bestpracticesguide/networking-outbound.html#networking-private-subnet
