In native cloud environments, classic monitoring tools reach their limits when monitoring transient objects such as containers. Prometheus closes this gap, which Kubernetes complements, thanks to its conceptual similarity, simple structure, and far-reaching automation.
Linux uses the Logical Volume Manager to manage large hard drives and mass storage clusters efficiently. We look at various graphical tools that help serve up logical volumes and volume groups.
Internet providers often market their open interfaces as RESTful, but is this true of the APIs, especially when no standard exists? We introduce some REST providers and look at how closely their API architectures reflect the REST principle.
The OpenStack cosmos cannot ignore the trend toward containers. If you want to combine both technologies, projects like Magnum, Kolla, and Zun come into play. Which one?
If you run microservices in containers, they are forced to communicate with each other – and with the outside world. We explain how to network pods and nodes in Kubernetes.
Despite the abundance of tools that test code and help improve the effectiveness of a continuous integration pipeline, automated security testing is much more difficult to get right than it might appear.
As Prometheus gave fire to mankind, the distributed monitoring software with the same name illuminates the admin's mind in native cloud environments, offering metrics for monitored systems and applications.
