In my prior post, I described how OpenStack from Red Hat frees you to pursue your business with the peace of mind that your cloud is secure and stable. Red Hat has several products that enhance OpenStack to provide cloud management, virtualization, a developer platform, and scalable cloud storage.
Cloud Management with Red Hat CloudForms
CloudForms contains three main components
Insight – Inventory, Reporting, Metrics
Control – Eventing, Compliance, and State Management
Automate – Provisioning, Reconfiguration, Retirement, and Optimization

As your IT evolves toward an open, cloud-enabled data center, you can take advantage of OpenStack’s benefits: broad industry support, vendor neutrality, and fast-paced innovation.
As you move into implementation, your requirements for an OpenStack solutions shares a familiar theme: enterprise-ready, fully supported, and seamlessly-integrated products.
Can’t we just install and manage OpenStack ourselves?
OpenStack is an open source project and freely downloadable. To install and maintain OpenStack you need to recruit and retain engineers trained in Python and other technologies. If you decide to go it alone consider:
How do you know OpenStack works with your hardware?
Does OpenStack work with your guest instances?
How do you manage and upgrade OpenStack?
When you encounter problems, consider how you would solve them? Some examples:

OpenStack is not a software application that just runs on top of any random Linux. OpenStack is tightly coupled to the operating system it runs on and choosing the right Linux operating system, as well as an OpenStack platform, is critical to provide a trusted, stable, and fully supported OpenStack environment.
OpenStack is an Infrastructure-as-a-Service cloud management platform, a set of software tools, written mostly in Python, to manage hosts at large scale and deliver an agile, cloud-like infrastructure environment, where multiple virtual machine Instances, block volumes and other infrastructure resources can be created and destroyed rapidly on demand.

Red Hat Enterprise Linux OpenStack Platform 6: SR-IOV Networking – Part I: Understanding the Basics
Red Hat Enterprise Linux OpenStack Platform 6 introduces support for single root I/O virtualization (SR-IOV) networking. This is done through a new SR-IOV mechanism driver for the OpenStack Networking (Neutron) Modular Layer 2 (ML2) plugin, as well as necessary enhancements for PCI support in the Compute service (Nova).
In this blog post I would like to provide an overview of SR-IOV, and highlight why SR-IOV networking is an important addition to RHEL OpenStack Platform 6. We will also follow up with a second blog post going into the configuration details, describing the current implementation, and discussing some of the current known limitations and expected enhancements going forward.

Last week we announced the release of Red Hat Enterprise Linux OpenStack Platform 6, the latest version of our cloud solution providing a foundation for production-ready cloud. Built on Red Hat Enterprise Linux 7 this latest release is intended to provide a foundation for building OpenStack-powered clouds for advanced cloud users. Lets take a deeper dive into some of the new features on offer!
IPv6 Networking Support
IPv6 is a critical part of the promise of the cloud. If you want to connect everything to the network, you better plan for massive scale and have enough addresses to use. IPv6 is also increasingly important in the network functions virtualization (NFV) and telecommunication service provider space.
This release introduces support for IPv6 address assignment for tenant instances including those that are connected to provider networks; while IPv4 is more straight forward when it comes to IP address assignment, IPv6 offers some more flexibility and options to choose from. Both stateful and stateless DHCPv6 are supported, as well as the ability to use Stateless Address Autoconfiguration (SLAAC).

Based on the community OpenStack “Juno” release and co-engineered with Red Hat Enterprise Linux 7, the enterprise-hardened Version 6 is aimed at accelerating the adoption of OpenSack among enterprise businesses, telecommunications companies, Internet service providers (ISPs), and public cloud hosting providers.
Since the first version released in July 2013, the “design principles” of Red Hat Enterprise Linux OpenStack Platform product offering are:

This week we announced the general availability of Red Hat Enterprise Virtualization 3.5. Red Hat Enterprise Virtualization 3.5 allows organizations to deploy an IT infrastructure that services traditional virtualization workloads while building a solid base for modern IT technologies.
Because of its open standards roots, Red Hat Enterprise Virtualization 3.5 enables IT organizations to more rapidly deliver and deploy transformative and flexible technology services in 3 ways:
Deep integration with Red Hat Enterprise Linux
Delivery of standardized services for mission critical workloads
Foundation for future looking, innovative, and highly flexible cloud enabled workloads built on OpenStack
Deep integration with Red Hat Enterprise Linux
Red Hat Enterprise Virtualization 3.5 is co-engineered with Red Hat Enterprise Linux including the latest version, Red Hat Enterprise Linux 7, which is built to meet modern data center and next-generation IT requirements. Due to this tight integration, Red Hat Enterprise Virtualization 3.5 inherits the innovation capabilities of the world’s leading enterprise Linux platform.

Adam Jollans is the Program Director for Cross-IBM Linux and Open Virtualization Strategy IBM Systems & Technology Group
IBM and Red Hat have been teaming up for years. Today, Red Hat and IBM are announcing a new collaboration to bring Red Hat Enterprise Virtualization to IBM’s next-generation Power Systems through Red Hat Enterprise Virtualization for Power.
A little more than a year ago, IBM announced a commitment to invest $1 billion in new Linux and open source technologies for Power Systems. IBM has delivered on that commitment with the next-generation Power Systems servers incorporating the POWER8 processor which is available for license and open for development through the OpenPOWER Foundation. Designed for Big Data, the new Power Systems can move data around very efficiently and cost-effectively. POWER8’s symmetric multi-threading provides up to 8 threads per core, enabling workloads to exploit the hardware for the highest level of performance.
Red Hat Enterprise Virtualization combines hypervisor technology with a centralized management platform for enterprise virtualization. Red Hat Enterprise Virtualization Hypervisor, built on the KVM hypervisor, inherits the performance, scalability, and ecosystem of the Red Hat Enterprise Linux kernel for virtualization. As a result, your virtual machines are powered by the same high-performance kernel that supports your most challenging Linux workloads.

By, Federico Simoncelli, Principal Software Engineer, Red Hat
As a software engineer working on the Red Hat Enterprise Virtualization (RHEV), my team and I are driven by innovation; we are always looking for cutting edge technologies to integrate into our product.
Lately there has been a growing interest in Linux containers solutions such as Docker. Docker provides an open and standardized platform for developers and sysadmins to build, ship, and run distributed applications. The application images can be safely held in your organization registry or they can be shared publicly in the docker hub portal (http://registry.hub.docker.com) for everyone to use and to contribute to.
Linux containers are a well-known technology that runs isolated Linux systems on the same host sharing the same kernel and resources as cpu time and memory. Containers are more lightweight, perform better and allow more density of instances compared to full virtualization where virtual machines run dedicated full kernels and operating systems on top of virtualized hardware. On the other hand virtual machines are still the preferred solution when it comes to running highly isolated workloads or different operating systems than the host.

The OpenStack 10th release added ten new storage backends and improved testing on third-party storage systems. The Cinder block storage project continues to mature each cycle exposing more and more Enterprise cloud storage infrastructure functionalities.
Here is a quick overview of some of these key features.
Simplifying OpenStack Disaster Recovery with Volume Replication
After introducing a new Cinder Backup API to allow export and import backup service metadata in the Icehouse release, which allowed “electronic tape shipping” style backup-export & backup-import capabilities to recover OpenStack cloud deployments, the next step for Disaster Recovery enablement in OpenStack is the foundation of volume replication support at block level.
