Even so, the inventors of the technology hype cycle have referred to cloud computing as “one of the most hyped and confusing terms in the history of IT.” If you believed the hyperbole, except for a few Luddites and technological relics, you’d think every enterprise has everything running in the cloud. But the truth is a little more…

Pluribus Networks has significantly upgraded its switch-fabric software to provide a better handle on distributed, containerized enterprise-cloud resources. The upgrades add three new fabric-monitoring capabilities—FlowTracker, KubeTracker, and Virtualized Packet Broker Service—to Netvisor One, the company’s virtualized Linux-based NOS that provides Layer 2 and Layer 3 networking and distributed fabric intelligence. The NOS virtualizes switch hardware and implements the company’s Adaptive Cloud Fabric software-defined networking package. Adaptive Cloud Fabric operates without a controller and can be deployed…

In the first part of this series, we looked at building workflows around IST (Intersight Services for Terraform) automations to provision IKS (Intersight Kubernetes Service) infrastructure and deploy a sample cloud-native application with ICO (Intersight Cloud Orchestrator). In part 2 and part 3, we leveraged IST and ICO to do a complete deployment of a multi-service Tomcat application and instrumentation for AppDynamics insights. Then in part 4, we created and executed TFCB (Terraform for Cloud…

Throughout this article, I’ll detail the compiling modules with Cython method/solution to the challenge of protecting a Python-based codebase. Cython is a static compiler for Python and Cython programming languages, it simplifies the job of writing Python C extensions. Cython allows us to compile Python…
