notes
Valid values, which determines your range of valid values for the memory parameter:
256 (.25 vCPU) - Available memory values: 0.5GB, 1GB, 2GB
512 (.5 vCPU) - Available memory values: 1GB, 2GB, 3GB, 4GB
1024 (1 vCPU) - Available memory values: 2GB, 3GB, 4GB, 5GB, 6GB, 7GB, 8GB
2048 (2 vCPU) - Available memory values: Between 4GB and 16GB in 1GB increments
4096 (4 vCPU) - Available memory values: Between 8GB and 30GB in 1GB increments
This default is set in the underlying FargateTaskDefinition construct.

When system memory is under contention, Docker attempts to keep the container memory within the limit. If the container requires more memory, it can consume up to the value specified by the Memory property or all of the available memory on the container instance—whichever comes first.

After dequeuing, the processor has this much time to handle the message and delete it from the queue before it becomes visible again for dequeueing by another processor. Values must be between 0 and (12 hours).

If a vpc is specified, the cluster construct should be omitted. Alternatively, you can omit both vpc and cluster.

Use this method instead of instanceof to properly detect Construct instances, even when the construct library is symlinked.
Explanation: in JavaScript, multiple copies of the constructs library on disk are seen as independent, completely different libraries. As a consequence, the class Construct in each copy of the constructs library is seen as a different class, and an instance of one class will not test as instanceof the other class. npm install will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the constructs library can be accidentally installed, and instanceof will behave unpredictably. It is safest to avoid using instanceof, and using this type-testing method instead.
Parameters
xxxxX— Any object.
Returns: true if x is an object created from a class which extends Construct.
