Tech Roundup - January 2021

I’ve not managed to do one of these ‘Tech Roundups’ since June 2020, and I wasn’t going to sift through 7 months of saved links and stuff, so this is a fresh start using the last 2 months data. Also, I’ve tried to be a bit more discerning with what I link, which is why I’ve put a section at the bottom of the post entitled “Go to Places for Regular Tech Updates”. My intention is to do these posts bimonthly going forward.
 
Azure Stack HCI
 
Azure Stack HCI solution overview
https://docs.microsoft.com/en-us/azure-stack/hci/overview
“This is a dedicated hyperconverged operating system based on Windows Server Core and managed by Windows Admin Center, which is designed to make it easier to deploy Hyper-V with Storage Spaces Direct (S2D). This is for on-premises Hyper-V! What makes the offering different from regular Hyper-V though, is that it is delivered as an Azure hybrid service: it comes with a monthly subscription cost and it is connected to Azure.”

The NetApp Data Science Toolkit is a Python library that makes it simple for data scientists and data engineers to perform various data management tasks, such as provisioning a new data volume, near-instantaneously cloning a data volume, and near-instantaneously snapshotting a data volume for traceability/baselining.
