With the newest Docker Enterprise Edition, you can now have Docker clusters composed of nodes running different operating systems.
Three of the key OSes supported by Docker—Windows, Linux, and IBM System Z—can run applications side by side in the same cluster, all orchestrated by a common mechanism.
Clustering apps across multiple OSes in Docker requires that you build per-OS images for each app. But those apps, when running on both Windows and Linux, can be linked to run in concert via Docker’s overlay networking.
The primary objective of the research was to profile Node.js users, understand usage patterns and trends and identify potential areas of improvement. With over 8 million Node.js instances online, three in four users are planning to increase their use of Node.js in the next 12 months. Many are learning Node.js in a foreign language with China being the second largest population outside of the U.S. using Node. Want to get a better understanding on how people are using and learning Node.js?

A Microservices architecture makes it possible to isolate failures through well-defined service boundaries. But like in every distributed system, there is a higher chance for network, hardware or application level issues. As a consequence of service dependencies, any component can be temporarily unavailable for their consumers. To minimize the impact of partial outages we need to build fault tolerant services that can gracefully respond to certain types of outages.
