#freeITBM VMware ITBM Free? (Opinion)

So lately there has been more discussion around the office whether we should move workloads to the 'cloud'?  AWS being the obvious 800lb gorilla.  I recently attended an AWS Essentials training and came out of it really impressed w/ their offering.  So much so, I thought, 'yeah, it might be time to diversify out of my VMware only mindset.'

That being said, 'cost' is a huge factor.  Not to mention security and a slew of other things, but we'll focus on cost being the topic.  How in the world do you calculate cost?  VMware had Chargeback, but that tool was a pain and quite frankly useless.  Now they have ITBM which is a very simplified tool @ it's core, but has some pretty impressive capabilities.

Amazon has a calculator, but honestly, I feel like that it is more than likely skewed in favor of AWS.  So this leads me to the idea that VMware needs to take the "Progressive" approach of 'compare' our prices to our competitors and choose what&…

Amazon Terms translated to VMware (How I understand them anyway)

Feel free to comment.  I'm just taking a simplified view.

Amazon EC2 = VM or vSphere Amazon EBS (Elastic Block Store) Volume = vmdk / RDM Amazon S3 = NAS / Windows File Share / NFS Volume / Etc. Amazon AMI = vSphere Template/OVF (Basic OS w/ or w/o applications pre-installed) Amazon RDS = Managed RDS DB (No OS or SQL server to manage) just DB instance. Amazon Cloudwatch = vCenter Operations Manager / HP Insight / SiteScope / Monitoring / Etc. Amazon Elastic Beanstalk = vFabric / Pivotal? Amazon CloudFormation = vApp / VMware vCloud Automation Center / VMware Orchestrator (Granular Blueprint)

Useful Powershell .NET method to convert DNS name to IP

Just thought this was useful, so decided to post it as a reminder for myself or anyone else really.
[system.net.dns]::gethostaddresses("www.vmware.com")
The reverse being:
[system.net.dns]::gethostbyaddress("23.64.19.51")
Here is how I used it w/ PowerCLI:
$VMHosts = Get-VMhost $VMHosts | select Name, @{Name="IP";Expression={[system.net.dns]::gethostaddresses($_.Name)}}
This information can be particularly useful if you need IP's for firewall rule tables. Source: http://blogs.msdn.com/b/powershell/archive/2006/06/26/647318.aspx
