Key Takeaways: CoreOS and Docker will fundamentally change the way SaaS companies deliver software. CoreOS and Docker used together provide a compelling package by combining an “operating system as a service” and an application container to run applications in isolation from the operating system. Security professionals should know that the introduction of these technologies will mitigate some traditional risks while creating others.
CoreOS in particular is interesting in the way that it handles operating system updates and patches using an active/passive partition scheme. More information here.
The ability to sanely roll operating system updates into deployment lifecycle will solve a major pain point for SaaS operations. The dirty little secret that is while many agile shops are starting to push code out “continuously”, operating systems are often left either untouched or unpatched.
CoreOS will help make “infrastructure as code” less buzzword and more reality in the not too distant future.
