Azure Service Fabric implements great concepts of microservices ( sorry for saying that so simplified ), there’s a lot of demos and docs which demonstrate nice pictures and moving boxes, but I surely see that most important and key basement features of that service are tough to find, especially for those who just started with Service Fabric.

• Service Fabric cluster capacity planning considerations – great doc which describes underlying layer of Service Fabric which is Azure Scale Set with different node types

Q: How to get Azure VM external IP address ( if you not use PublicIP service ) ?

A:  If you’re not using ReservedIP service field PublicIP will be empty ( as soon as there’s no reserved IP ) for command Get-AzureVM. I using Swtich-AzureMode just in case to be sure that we’re in right Azure mode in powershell right now.

PS C:\> Switch-AzureMode -Name AzureServiceManagement
PS C:\> Get-AzureVM


PS C:\> Get-AzureVM -ServiceName "abokov-jelastic" | Select-object  Name, DNSName, *IP*


Name                    : abokov-jelastic
DNSName                 : http://abokov-jelastic.cloudapp.net/
IpAddress               : 10.0.0.4
PublicIPAddress         :
PublicIPName            :
PublicIPDomainNameLabel :
PublicIPFqdns           : {}
OperationDescription    : Get-AzureVM

You may see that this VM have DNS name, internal IP, but public IP is empty, nevertheless that there’s is an external IP address which is linked to that VM. To get external IP you may use command Get-AzureEndPoint which returns all information about all endpoints for that cloud service – in my case I have 7 open ports and to make this more readable I select only few fields from output.

PS C:\> Get-AzureVM -ServiceName "abokov-jelastic" | Get-AzureEndPoint | Select-Object Name, Port , *ip*

Cloud computing is a term that originally meant elastic on demand computing but is now a term applied elastically by marketdroids to any form of virtualisation.
This is part of the transition from 2009’s vBullshit to BaaS, Bullshit as a Service.
