SDN with Red Hat OpenStack Platform: OpenDaylight Integration

OpenDaylight is an open source project under the Linux Foundation with the goal of furthering the adoption and innovation of software-defined networking (SDN) through the creation of a common industry supported platform. Red Hat is a Platinum Founding member of OpenDaylight and part of the community alongside a list of participants that covers the gamut  from individual contributors to large network companies, making it a powerful and innovative engine that can cover many use-cases.

Troubleshooting Networking with RHEL OpenStack Platform: meet ‘plotnetcfg’

Network troubleshooting can be hard. Network troubleshooting in a complex distributed system like OpenStack can be even harder. With a typical Neutron deployment using the Open vSwitch (OVS) plug-in, one can expect rich networking configurations on the Red Hat Enterprise Linux OpenStack Platform nodes, the Compute and Controller nodes in particular.

While the network implementation details are well hidden from the end customer (who interfaces with the Neutron API or the Horizon Dashboard), the actual backend implementation involves the creation of various Linux devices, bridges, tunnel interfaces, and network namespaces. This is where the “magic” happens, and how OpenStack tenants can create and consume network resources such as networks, IP subnets and virtual routers, and get proper communication for their applications.

How Red Hat’s OpenStack partner Networking Solutions Offer Choice and Performance

Successfully implementing an OpenStack cloud is more than just choosing an OpenStack distribution. With its community approach and rich ecosystem of vendors, OpenStack represents a viable option for cloud administrators who want to offer public-cloud-like infrastructure services in their own datacenter.  Red Hat Enterprise Linux OpenStack Platform offers pluggable storage and networking options.  This open approach is contrary to closed solutions such as VMware Integrated OpenStack (VIO) which only supports VMware NSX for L4-L7  networking or VMware Distributed switch for basic L2 networking .

Below are some of the networking partners who have certified their OpenStack Networking plugins with Red Hat Enterprise Linux OpenStack Platform and will be on display at VMworld 2015, San Francisco, at the Red Hat booth, 528; (Cisco is at booth 1721). See exhibitor map

Open, modular architecture brings flexibility and agility to the data center

Nuage Networks logoRHOSCIPN_logo_small

 

Recently there has been a flurry of activity in the Open Source community – blog posts, articles, tweets. The discussion is about Application deployment and Policy enforcement in the data center. Why all the banter?  Reason – it is simpler for developers to set up services using an application-centric view rather than a network-centric view; and it allows them to do so without sacrificing application or data security. Nuage Networks has been a strong advocate of an Application Centric Policy framework. As a result, the Nuage Virtualized Services Platform (VSP) supported integrated policy from day one when we launched our product a year ago. We have continued to enhance this policy framework, which aligns with the current trends.

We are delighted that the Open Source community is beginning to share our point of view. This is reflected with the Neutron Group Policy extension work in OpenStack. Nuage is strongly committed to supporting this effort by contributing to the Neutron Core development. As part of this effort, we will also be providing support for Nuage VSP as a Network Policy provider in OpenStack

Why Brocade’s Close Collaboration With Red Hat Matters To Your Business

Cloud.
Open.
Software-Defined.

These are the hot buzzwords of the last year or two, yes, but not without cause. Cloud is finally becoming real, albeit a bit differently than many envisioned a few years ago: the relative aggressiveness of public providers compared to most enterprises has created a functional chasm that small and midsize enterprises are unlikely, at this point, to try to fill—it’s easier to outsource many workloads.

The economic realities of the cloud marketplace dictate that service agility trumps almost everything else. Until very recently, this could be accomplished via tight (and expensive, and often lengthy) integration between the physical infrastructure and some sort of cloud management framework, most of which were retrofitted to deal with VMs. Generally the best way to make this work was rigorous standardization of the physical infrastructure.

The Importance of Integrating Datacenter Infrastructure

By, Steve Gordon, Product Manager, Red Hat
January 23, 2014

This week heralds a refresh of Red Hat’s cloud portfolio offerings, including Red Hat Cloud Infrastructure 4.0, Red Hat Enterprise Linux OpenStack Platform 4.0, and the latest release of Red Hat’s traditional data center virtualization management platform, Red Hat Enterprise Virtualization 3.3.

We’ve put a lot of effort into our long-term cloud product strategy and the updates this week show the beginning of those efforts coming together. With this refresh, it’s clear that integration and management is the key theme behind the marketing launch activities. However, delivering real, tangible, and deployable value to our customers through Red Hat infrastructure software, is the key to success for us and this update provides you (us) the first step.

So why is integration so important in your data center? And why integrate with OpenStack? The answer lies within your own existing infrastructure, as well as your long-term plans. No, I don’t have magical powers to see your datacenter or your plans, but statistically-speaking, I can see just fine.
