- Add Private Route 53 DNS to your AWS VPC | CloudTrek – A really cool feature of Amazon’s Route 53 DNS Management Service is the private hosted DNS zone. Basically, you get the ability to manage the DNS in your private VPC without setting up your own DNS infrastructure (yuck!)

Note 3: if you are using linux, you can use as DNS 169.254.169.253 it won't work on windows 2008 Ref: http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_DHCP_Options.html http://docs.aws.amazon.com/Route53/latest/DeveloperGuide/hosted-zones-private.html http://aws.amazon.com/route53/faqs/ ]

- Set up public and private subnets using AWS VPC — Mike Melnicki’s Blog – This is a step-by-step guide on how to set up public and private subnets for running a service on an internal network within AWS. This guide will also set up a bastion host (or jump host) and show you how you can easily ssh in to the hosts within your private subnet via the bastion host. All of this stuff can be done via the AWS web console, but I thought it would be helpful to show the specific commands and provide some commentary about what is happening on each step.

In this post we will explain how to use CloudWatch to monitor important resources it can’t monitor by default.
