[elasticluster] Re: Status of Azure support in Elasticluster

[Dave Steinkraus]

Hi all,

Weighing in as the original author of the Azure provider for Elasticluster. 
At the time I wrote it (2015), the Azure APIs I was writing to were already 
on their way out, to be replaced by a whole new set, which are 
"declarative" - 'Syntax that lets you state "Here is what I intend to 
create" without having to write the sequence of programming commands to 
create it. The Resource Manager template is an example of declarative 
syntax. In the file, you define the properties for the infrastructure to 
deploy to Azure.' [
https://docs.microsoft.com/en-us/azure/azure-resource-manager/resource-group-overview]
 
Back then, there was no firm date for these new APIs to be released.

I'm sorry but not surprised that the old APIs have stopped working 
correctly. I haven't kept up with Azure, but I'm sure at this point the 
only way forward is to rewrite the provider using the current APIs. 
Unfortunately, very little of the old code is likely to be reusable. (On 
the upside, I'll bet the new APIs work much better and more simply than the 
old ones, which were never really stable.)

I have a lot of commitments right now, but I'm willing to put some time 
into scoping out a rewrite. That's all I can promise.

Regards,
Dave

Hi Riccardo. Seems like elasticluster is thriving under your leadership
(based on the github notifications, which I still get).

As I said, I haven't kept up with Azure (been more involved with AWS) so
I'm coming in knowing less than you about the new APIs.

I can look into your questions - a quick google didn't yield much.

Best,
Dave
