Example text

Kubernetes also has an excellent design document on secret management, which will be the basis for a secret management framework. Location If your services running on one host or virtual machine are all services that have the same level of access to the same data, then you can potentially worry less about isolation. This is after all no worse than a monolithic application after all, where there is no real isolation of components. While microservices do allow you to build a more secure architecture with high levels of privilege separation, doing this for applications not having access to sensitive data is not a priority.

The important point with these is to stop an application affecting others running on the same host by using up all the memory, IO nadwidth or CPU time. Depending on how you set up containers there may well still be some interference. For example, cache will be shared unless you completely allocate CPUs, and IO is contended if you share IO devices such as network or disks. How much this matters depends upon workloads and how much you oversubscribe resources, but usually this is a throughput rather than a security issue, although side channel attacks are possible.

Over the last 10 years or so these environments have been fairly static within companies. We found a another great Docker environment example from RelateIQ. They are doing something interesting that could break up the standard environment model. RelateIQ has a web environment per branch fully orchestrated using AWS Beanstalk. This is a new type of infrastructure environment using Docker technology through their CI/CD infrastructure. They have essentially disconnected the web tier from the data tier.
