家住魔仙堡 提交于 2020-06-15 10:10:15

Following is the script to connect to instance on public IP: s3_client = boto3.client('s3') s3_client.download_file('mybucket','key/mykey.pem', '/tmp/mykey.pem') k = paramiko.RSAKey.from_private_key_file

What is the AWS Public IP Limit? (Public IP not Elastic IP)

試著忘記壹切 提交于 2020-06-14 06:36:25
问题 Is there a limit to the number of Public IPs you can use for a given AWS region? (Not Elastic IPs) Note - I know that you are limited to 5 Elastic IPs. However, if you choose "auto assign IP" when creating and AWS instance, you are given an IP which changes on restart. My question is what the limit is on these "Public IPs" that change every time your instance is stopped and started? 回答1: There is no limit on Public IPs that you can use in AWS. Limit is only on number of instances that you can

Multi node cluster installation with h2o on AWS EC2

别来无恙 提交于 2020-05-29 04:16:07
问题 I was wondering about how to set up a h2o cluster using multiple AWS EC2 instances and R-Studio. I am not a computer scientist, so sorry for the trivial questions (!)
