Comparing Toolsets for Automating Cloud Infrastructure

As organizations begin considering the addition of Cloud utilization within their environments, we frequently see the entry points focused on application development. Specifically, IT organizations need to make the proper environments readily available to developers to facilitate the required pace of innovation in today’s market. Without this capability, organizations risk their first-to-market strategy and increased competition from rival organizations.

vExpert Stickers – 2017 Edition

Once again, I’ve teamed up with a member of the vCommunity to give out free vExpert stickers. This year, Jim Jones is helping out.

This was a goal I’ve had for quite a while and, a month or two ago, I finally took the plunge and scheduled the exam.

As a direct result, my confidence on the AWS platform increased substantially and got my week started off with a bang!...

Amazon Web Services – Sizing a VPC and Subnet

Shorter post here but wanted to quickly share some information regarding IP addressing within an AWS VPC and subnets. As you might know, when you create a VPC you specify the CIDR block that you’ll be utilizing. Once your VPC is created, you’ll need to create subnets within that CIDR block for resources to attach to. For example, if you create a VPC using a CIDR block of, you can create subnets using 10.0.x.x/x. Therefore subnets created within this VPC could be,, etc. These subnets don’t have to be limited to a /24, they can be...
