How do you remedy this situation?
Add an additional ENI
Change to a larger Instance
Use DirectConnect between EC2 and S3
Use EBS PIOPS on the local volume
Explanations:
Adding an additional Elastic Network Interface (ENI) does not increase the overall network throughput of the instance. An m1.small instance has limited network capabilities, and simply adding another ENI will not resolve the bottleneck issue.
Changing to a larger instance will provide better network performance due to increased network bandwidth and resources. Larger instance types offer higher network throughput, which can significantly improve the speed of data uploads to S3.
AWS Direct Connect is a dedicated network connection from on-premises to AWS services, not between EC2 and S3 within the same region. It does not address the issue of network throughput directly between an EC2 instance and S3 in the same region.
Using EBS Provisioned IOPS (PIOPS) affects the performance of EBS volumes and disk I/O operations but does not directly impact network throughput when uploading data to S3. This option is not relevant to the network bottleneck issue.
I plot that the answer is:
Change to a larger Instance
