These posts seem to think that what has been written is either wrong or misinformation.  Actually, the issue is poor communication on Microsoft’s part.  However, what’s subsequently been said has left more questions than… Read more »

Block is Not the Solution for Persistent Container Storage

It appears we’re reaching a consensus that persistent storage is needed for containers.  Despite early resistance, with an assumption that containers and their data should be transient, the logic of data persistence is starting to take hold.  To be honest it simply makes sense.

Scale Computing Debuts HC3 in Google Cloud Platform

Hyper-converged infrastructure is a great technology for running a range of mixed workloads.  With HCI how do you manage DR?  Typically the standard solution might be to run up another cluster in a separate data centre and run both 50% active/active or have one purely for standby.  What about running in the public cloud?  With… Read more »

Building Data Storage With Containers

Note: Updated on 18 January 2017 to include OpenEBS. There’s an almost religious divide between those who see containers as entirely stateless objects and others taking a more pragmatic approach that says state and containers is an inevitable thing.  In the stateless model, data is assumed to be replicated and protected by many container instances. … Read more »

This week I’m in Seattle, the home of Starbucks, Boeing and Microsoft for DockerCon 2016.  Compared to the normal events I attend, this one promises to be a more “casual” affair, so I’m sporting polo shirts and vendor hoodies as my standard attire. One of the more interesting problems yet to be fully solved with… Read more »
