In the introduction to this series, I introduced you to my not-so-fictitious Client, which was using different toolsets for image creation and replication.
The question we are trying to answer (or at least provide clarity on), is: Should we create a custom image, or use the Azure Marketplace image?
So, which is the right answer?
Well, in the traditional IT Consultant answer: it depends.
To help, here’s a table listing the Pro’s and Con’s for each option, to help you decide.
Custom vs Marketplace Image
|Custom Image||Full control |
Pre-install agents, tools, etc.
Reusable across environments
|Many steps required to prepare/upload and use in Azure
Multiple versions/editions to create and manage monthly
Fixed OS disk size
|Marketplace Image||Pre-prepared/optimized image for Azure|
Patches already applied
Extensible with on-demand components
No monthly build/release maintenance
All patches applied
Must trust Microsoft's image development
I hope this series has provided you with enough information, on both sides, to help you in your decision.
