Musing on In-Guest iSCSI

Sorry I had to throw up in my mouth a bit.

Anyways. In general I am not a fan of using in-guest iSCSI for VMware environments (or really any virtualized environment), but the question does come up. And I find a surprising amount of customers using it in secret. So what of it? Why do I hate it? Why should one use it? Are there reasons to?

It has been a fun ride–definitely already incorporated some of my learnings into my solution work for on-premises integration and have some cool stuff coming. A lot of my work has been of course on using it, how to deploy EC2, how to deploy VMware Cloud on AWS, managing S3, CloudFormations, IAM, SSM, using the billions of other services in AWS. But much of my focus has been on listening to what people have seen, learned, and want to do with public cloud. AWS and the like have had a decent amount of runway now, so there have certainly been some lessons learned.
