According to the EC2 documentation, its more cost-effective to use the internal address to communicate between EC2 instances. What is the optimal way to communicate between EC2 and S3? Is there a notion of an "internal address" for S3 and is it any faster/more cost effective than fetching from public address?
http://aws.amazon.com/ec2/:
There is no Data Transfer charge
between Amazon EC2 and other Amazon
Web Services within the same region
(i.e. between Amazon EC2 US West and
Amazon S3 in US West)
http://aws.amazon.com/s3/:
There is no Data Transfer charge for
data transferred between Amazon EC2
and Amazon S3 within the same Region
or for data transferred between the
Amazon EC2 Northern Virginia Region
and the Amazon S3 US Standard Region.
so there is no need for a separate internal address.

We are running a self managed EC2 instances in the EKS Cluster. While upgrading control plane is managed by AWS, the worker nodes are self managed. For running security updates and patches, we use the latest optimized AMI and role out the new instances. Some of these are manual effort, what is the best automated approach that you are following to update/patch those self managed EC2 worker nodes?
Steps that we follow:
Look for the latest optimized AMI version released by AWS
Update the Launch configuration with new AMI
Scale up nodes with New AMI
Seamlessly transfer pods from old to new nodes
scale down and delete the old nodes.
The issue here after we update with new optimized AMI, we still find out some security updates that are listed during scanning those instances.
Some of these are manual effort, what is the best automated approach
I suggest to have a look at Managed Node Groups since that is an automated approach for the lifecycle management that you are doing.
Nodes run using the latest Amazon EKS optimized AMIs in your AWS account while node updates and terminations gracefully drain nodes to ensure that your applications stay available.
All managed nodes are provisioned as part of an Amazon EC2 Auto Scaling group that is managed for you by Amazon EKS. All resources including the instances and Auto Scaling groups run within your AWS account. Each node group uses the Amazon EKS optimized Amazon Linux 2 AMI and can run across multiple Availability Zones that you define.
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.
A similar Question is this
There is a separate service Data pipeline, which provides reliable data transfer between S3 and EC2

I am looking for a case study of companies that use Cloud message queueing.
What are the benefits of such a service over rabbitmq (if any)
I know there are several mature services like SQS of amazon, OnlineMQ and Linxter.
The advantage of Cloud Messaging service is the managing the MQ systems is not your head-ache. It is being pushed to the cloud service provider. Amazon SQS integrated very well with other Amazon AWS products like EC2,S3 so it is the choice if you are already on Amazon AWS infrastructure. But SQS performance way is low compared to RabbitMQ in terms of latency.
So if you want a Message Queue service which has customized needs, RabbitMQ (or any other MQ system) can be what you are looking for.
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.
