Very good session sir, you answered most of the questions which are quite confusing sometimes.

I think for Bastion/Jumpbox should be restricted to specific ip cidr range rather than open to whole world.. If anyone able to login to my bastion he/she can be able to login to my private EC2 as well. Let me know your thoughts on that 7:43

Hi, If we have a Windows Bastion Host what are the best practices to allow users ssh into Linux EC2 instance internally ? How can users securely save their keys on my Windows Bastion host, if they were to use key based authentication to ssh in ? Or is using username-password to ssh OK in this use case as users wont have to worry about saving passwords on the Bastion ?.

Hello Sandeep, I am trying to send some data to cloudwatch using put-metric-data with command "aws
cloudwatch put-metric-data --metric-name Latency --namespace Demotest
--timestamp 2017-06-20T11:27:00.000z --value 53 --unit Milliseconds" and
I am getting below error message:"Parameter validation failed:
Invalid
type for parameter MetricData[0].Timestamp, value:
2017-06-20T11:27:00.000z, type: <type 'unicode'>, valid types:
<type 'datetime.datetime'>, timestamp-string"I am using UTC timezone and if I exclude timestamp, it works fine.
Thanks

I'm one of your follower to learn AWS. I feel this is one of the good place to know about AWS and learn.
I'm wondering about Bastion concept and I'm trying to find a video
about this here. Consider I have 6 Windows EC2 instances but I don't
want to buy EIP which costs $6* / month and assign for those EC2
instance. How can I access those 6 windows EC2 instance using RDP or
another concept. Consider that I have to open 4 windows instance at a
time. Can you please send me the link if available. Looking forward.
Thanks in advance.

Hi, Could you please tell why we should not use NAT Instance/ NAT Gateway as
Bastion Host? In other word do we have to keep both separately?
