New and updated features in Red Hat Virtualization (RHV) 4, along with seamless provisioning of services between traditional and cloud workloads, could help RHV make up ground on VMware and Hyper-V.
Large environments such as clouds pose demands on the network, some of which cannot be met with Layer 2 solutions. The Border Gateway Protocol jumps into the breach in Layer 3 and ensures seamlessly scalable networks.
A natural consequence of software-defined storage and software-defined data centers is the software-defined wide area network, or the Internet connections between locations and cloud services.
Any OpenStack installation that hosts services and VMs for several customers poses a challenge for the security-conscious admin. Hardening the overall system can turn the porous walls into a fortress – but you'll need more than a little mortar.
If you spend very much of your time pushing containerized services from server to server, you might be asking yourself: Why not databases, as well? We describe the status quo for RDBMS containers.
Virtualization solutions isolate their VM systems far more effectively than a container host isolates its guests. However, implementation weaknesses in the hypervisor and configuration errors can lead to residual risk, as we show, using KVM as an example.
