If I have my files hosted on Amazon S3, why would I need to use a cloud for North America? Wouldn't it just download from S3?
S3 has multiple regions. Currently there are four. Each S3 bucket is in a specific region. If you're using EC2 you will get the lowest prices (free bandwidth) and best performance (latency and bandwidth) if you use an S3 bucket in the same region as your EC2 instance.

We have data pipelines build to move data constantly from S3 to RedShift. I understand data is transferred over to redshift using copy command with HTTP/SSL protocol. My questions whether this traffic stays within VPC internal network or go over internet?
what if I'm transferring from S3 bucket to another S3 bucket in a different region, does it go over internet?
Amazon S3 has its own "back-end" connection to Amazon S3. The connection does not go via the VPC.

When transferring between Amazon S3 buckets in different regions, traffic will use Amazon-operated networks if they are available. (I'm not sure if data is transferred between two regions where there is no direct Amazon network connection.) However, the traffic is always encrypted.
I am transferring data from Google Cloud Storage to AWS S3 using distcp in EMR(I have made some configuration changes to EMR to achieve this). Is the data transfer secure? If not, what are the other options?
Amazon EC2 creates automatically if I use S3?
I use only S3.
No, if you use S3 it won't automatically create an Amazon EC2 Instance if that is what you are referring to. Can you clarify your question.
An AWS EC2 instance/server is different from S3.
If you use AWS S3 to upload/download store files no EC2 servers will be launched.
You can access these files through AWS console or through AWS Cli on your local machine.
What is the network bandwidth between Amazon ec2 instances and Amazon S3? I am trying to figure out how long it would take me to copy data from Amazon S3 to Amazon EC2 (and vice versa)
This isn't published information, but ... it's fast.
On smaller instance classes, total Ethernet bandwidth available to the instance can easily be consumed by requests to S3, implying that the limitation isn't the connection to S3.
Provisioning a VPC endpoint for S3 access might also improve throughput to S3.
Bottom line, benchmark it. You will, of course, want to use a bucket that's provisioned in the same region as the instance, for both cost and performance reasons. Data transfer between EC2 and S3 is not billed within a region.
How can we improve the upload speed of files from EC2 to S3, when the EC2 machine and S3 in different regions?
I have created a file which is of 1GB, and i need to upload the same to S3. Here the EC2 machine and S3 bucket were located in different regions(but Same Country)
Both were in US but the region is East and west
Anyone please assist on this
Unfortunately, there is not much you can do here. You are going to be limited to the available bandwidth between each datacenter.
You do have the option of moving your instance or bucket, to the other region. How much work this will be will depend on how much data you have in your bucket, or how you are currently using your instance.

There is a separate service Data pipeline, which provides reliable data transfer between S3 and EC2
