rdo

Overview

In this article we will focus on installing and configuring OpenStack Mitaka using RDO and the packstack installer. RDO is a community platform around Red Hat’s OpenStack Platform. It allows you to test the latest OpenStack capabilities on a stable platform such as Red Hat Enterprise Linux (RHEL) or CentOS. This guide will take you through installing the OpenStack Liberty release, configuring networking, security groups, flavors, images and are other OpenStack related services. The outcome is a working OpenStack environment based on the Mitaka release that you can use as a baseline for testing your applications with OpenStack capabilities.

Red Hat Enterprise Virtualization (RHEV) – Management Options

oVirt_300x100

Overview

RHEV has two separate distinct layers, the hypervisor itself and management. The hypervisor layer, RHEV-H is of course built on Red Hat Enterprise Linux (RHEL) and utilizes KVM for the hypervisor technology. RHEV-H can be configured using pre-built RHEV-H image or using standard RHEL. The management layer, Red Hat Enterprise Virtualization Management (RHEV-M) provides management for a multi-hypervisor environment and uses concepts such as datacenters, clusters, networks and storage domains to describe virtualization resources. In this article we will focus on options for configuring RHEV-M. The upstream opensource project behind RHEV-M is oVirt. There are two options as of RHEV 3.5 for configuring RHEV-M, standalone or hosted engine.

Overview

Containers, especially Docker container images have been on fire of late and it is simple to understand why? Docker container images give your development and operations organizations a major shot of adrenaline. The results are quite impressive. Applications are developed at never before seen speeds and as such organizations are able to deliver innovation to customers much faster. It’s all so easy, just get on Docker Hub, download a container and run it. So why isn’t everyone already doing this? Unfortunately it is not quite that simple. Enterprises have many other requirements such as security. Once IT operations gets involved they typically start asking a lot of questions. Who built this container? How is the container maintained? Who provides support for the software within the container? Does the software running within the container adhere to our security guidelines? How can we run security compliance checks within containers? How do we update software within containers?
