# How to scale up

There are two ways to scale up a service. First way is scaling vertical where we upgrade the instance to have more vCPU or memory. The second way is scaling horizontal and is achieved by setting up an autoscaling strategy or increase the running instances/tasks.

# Scaling vertical

Go to the task-definition overview en select the correct task definition. Create a new revision from the current used task definition and adjust the task memory/CPU units to the desired values. Save the task definition and this will create a task definition with a new revision number. Trigger a manual deploy with the new task definition.

# Scaling horizontal

Got to the ECS service and update the service. You can now increase the instances or adjust the autoscaling strategy.
