The Road To High Availability for OpenStack

by Arthur Berezin — April 16, 2014

Why OpenStack High Availability is Important?
Many organizations choose OpenStack for it’s distributed architecture and ability to deliver Infrastructure-as-a-Service environment for scale-out applications to run on top of it, for private on premise clouds or public clouds. It is quite common for OpenStack to run mission critical applications. OpenStack itself is commonly deployed in Controller/Network-Node/Computes layout where the controller runs management services such as nova-scheduler that determines how to dispatch compute resources, and Keystone service that handles authentication and authorization for all services.

Although failure of the controller node would not cause disruption to already running application workloads on top of OpenStack, for organizations running production applications it is critical to provide 99.999% uptime of the control plane of their cloud, and deploy the controller in a highly available configuration so that OpenStack services are accessible at all times and applications can scale-out or scale-in according to workloads.

An Icehouse Sneak Peek – OpenStack Networking (Neutron)

by Nir Yechiel

Today’s datacenter networks contain more devices than ever before; servers, switches, routers, storage systems, dedicated network equipment and security appliances – many of which are further divided into virtual machines and virtual networks. Traditional network management techniques generally fall short of providing a truly scalable, automated approach to managing these next-generation networks. Users expect more control and flexibility with quicker provisioning and monitoring.

OpenStack Networking (Neutron) is a pluggable, scalable and API-driven system for managing networks and IP addresses. Like other aspects of the cloud operating system, it can be used by administrators and users to increase the value of existing datacenter infrastructure. Neutron prevents the network from being the bottleneck or limiting factor in a cloud deployment and gives users real self service over their network configurations.
Starting in the Folsom release, OpenStack Networking, then called Quantum, became a core and supported part of the OpenStack platform, and is considered to be one of the most exicting projects – with great innovation around network virtualization and software-defined networking (SDN). The general availability of Icehouse, the ninth release of OpenStack, is just around the corner, so I would like to highlight some of the key features and enhancements made by the contributors in the community to Neutron.

An Icehouse Sneak Peek – OpenStack Compute (Nova)

by Steve Gordon, Product Manager, Red Hat — March 11, 2014
It seems like it was only yesterday that the OpenStack community found itself gathering in Hong Kong to set the design goals for the Icehouse release. As we entered March development was still progressing at a fever pitch in the lead up to the feature freeze for the release but now the dust has started to settle and we are able to start getting a real feel for what OpenStack users and operators can look forward to in the Icehouse release.
Today I’ll be giving a sneak peak to just some of the changes made in one of the two projects that made up the original OpenStack release and today is still one of the largest – showing no signs of the innovation slowing downOpenStack Compute (Nova). OpenStack Compute is a cloud computing fabric controller, a central component of an Infrastructure as a Service (IaaS) system. It is responsible for managing the hypervisors on which virtual machine instances will ultimately run and managing the lifecycle of those virtual machine instances. This list is by no means exhaustive but highlights some key features and the rapid advances made by the contributors that make up the OpenStack community in a six month release cycle.

Repost: Deployment to Upgrade–Puppet OpenStack Modules Are Your Friends

by Red Hat Stack Blog

Since the announcement of RDO and Red Hat OpenStack at the Spring 2013 OpenStack Summit, these have arguably become two of the most popular ways to install OpenStack. Both use the puppet-openstack modules to install OpenStack, and are just a sampling of the OpenStack installers that are based on Puppet.

Repost: Why combine Red Hat Enterprise Linux and OpenStack? Integration and Ecosystem Benefits.

Originally posted on August 5, 2013, by Tim Burke, vice president, Cloud and Virtualization Development, Red Hat – Part 3 of a 4 part series [1]

Part 3.

In my last post, I discussed a small subset of the security, storage, networking, virtualization, and performance optimizations that make the Red Hat Enterprise Linux OpenStack Platform offering technically superior. Yet, as innovation continues in the vibrant upstream OpenStack and Linux communities, Red Hat’s integration work is ongoing. Our subscription model assures that customers will continue to have access to this ongoing stream of innovation –  innovation that is made possible through the tight coordination of the Red Hat Enterprise Linux development team, which now includes OpenStack components. The goals of that coordination include:

  • Component Integration – There are several parts of OpenStack that have dependencies on specific versions of run-times or system utilities. For example, there are specific networking modules required for software-defined networks (SDNs), specific versions of python run-times, custom Security-Enhanced Linux (SELinux) security policies, and even system tunings for virtualized guest environments. Piecing together the specific versions and making the completed whole function optimally can be a daunting challenge.

Repost: Why combine Red Hat Enterprise Linux and OpenStack? Technology Optimization Benefits.

by Tim Burke, Principal Product Manager, Red Hat — February 18, 2014

Originally posted on July 24, 2013, by Tim Burke, vice president, Cloud and Virtualization Development, Red Hat – Part 2 of a part 4 series [1]

Part 2.
OpenStack delivers a highly scalable cloud environment for a variety of applications. But, cloud workloads present new challenges for underlying operating system platforms. The nature of the cloud is to be agile, not static. Virtual machines are quickly created and destroyed in large numbers. Storage and networking need to be flexible and highly performant. Red Hat Enterprise Linux has evolved to match the pace and unique characteristics of cloud deployments and is optimized for OpenStack in several ways, including:

  • Security – Cloud environments don’t deploy applications on dedicated hardware. Rather, they deploy multiple virtual machines on top of a pool of generic hardware resources, with virtual machines often sharing the same hardware. In this deployment model, virtual machine isolation is a key security concern. Enter Red Hat Enterprise Linux and the fine-grained permission enforcement afforded by Security-Enhanced Linux (SELinux) at the file, network and user levels. In Red Hat Enterprise Linux OpenStack Platform, SELinux enforces specific policies that are unique to the needs of OpenStack, such as enabling OpenStack to configure network namespaces which utilize Openstack’s network services. The benefit of SELinux is to prevent different virtual guests from accessing network ports and connections maliciously. In this way, the security inherent in Red Hat Enterprise Linux enhances the security of OpenStack cloud environment.

Repost: The evolution of Red Hat Enterprise Linux, and the answer to “Who will be the Red Hat of OpenStack?”

by Tim Burke, Principal Product Manager, Red Hat — February 13, 2014

Originally posted on July 18, 2013 by Tim Burke, vice president, Cloud and Virtualization Development, Red Hat – Part 1 of a 4 part series [1]

Part 1.
Throughout its history, Red Hat Enterprise Linux has been been transformative in the information technology infrastructure platform arena. It was founded on the principles of bringing stability and a longer lifecycle required by commercial IT organizations to the rapidly changing, community-developed Linux operating system. This unleashed a wave of commoditized computing as Red Hat Enterprise Linux displaced expensive proprietary UNIX offerings, delivering customers lower costs and freedom from vendor lock-in.

The next wave of Red Hat Enterprise Linux focused on being first in the industry to offer the highest levels of security built into the mainstream product rather than being an obscure offshoot. This focus on security – including collaboration with the U.S. government’s National Security Agency (NSA) on Security-Enhanced Linux (SELinux) – paved the way for security-conscious governments and businesses around the globe to adopt Red Hat Enterprise Linux.

OpenStack Services Integration: Pros and Cons

by Flavio Percoco, Software Engineer, Red Hat — February 6, 2014

As many of you know, OpenStack is a fully distributed system. As such, it keeps its services (nova, glance, cinder, keystone, etc ) as decoupled as possible and tries to stick to most of the distribution paradigms, deployments strategies and architectures. For example, one of the main tenets throughout OpenStack is that every module should be using Shared Nothing Architecture (SNA) which states. that each node should be independent and self-sufficient. In other words, all nodes in a SNA are completely isolated from each other in terms of space and memory.

There are other distribution principles that are part of OpenStack’s tenets, however, this post is not about what principles OpenStack as a whole tries to follow, but rather on  how OpenStack sticks together such a heavily distributed architecture and makes it work as one. The first thing we need to do is evaluate some of the integration methods that exist out there and how they’re being used within OpenStack. Before we get there, let me explain what an integration method is.

7 Ways in which OpenStack Adoption Parallels Linux

by ghaff — January 23, 2014

By, Gordon Haff, Cloud Evangelist, Red Hat
January 27, 2014

In spite of its considerable momentum, there are still skeptics about whether OpenStack will ultimately succeed. My colleague Bryan Che tackled some of that skepticism in a blog post late last year and I’m not going to rehash his arguments here. Rather, I’m going to make some observations about how OpenStack is paralleling and will likely continue to parallel the adoption of another open source project that I think we can all agree has become popular and successful—namely Linux.[1]

OpenStack Parallel Linux

1. Part and parcel of a new approach to computing
Linux came about at a time when computing was changing. It had become distributed and the rise of the Web was leading to new functions and new requirements. Much of Linux’ early-on growth came from powering new Internet infrastructure.  It was from that beachhead that Linux branched out into more traditional enterprise operating system roles. Similarly, OpenStack is part of the cloud computing wave which is characterized by new levels of standardization and automation combined with an on-demand and self-service approach to delivering computing resources to users.

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.

Why You Need a Cloud Management Platform

by ghaff — January 7, 2014

By, Gordon Haff, Cloud Evangelist, Red Hat
January 7, 2014

Cloud infrastructure and cloud management. As an industry, we conflate these two things far too often.

This is understandable up to a point. Cloud computing architectures are relatively new and new architectural approaches often involve figuring out how functions are best partitioned and how they relate to each other. The process tends to be pragmatic; that’s how the networking stack first developed. That terminology is often morphing and inconsistently applied (innocently or otherwise) doesn’t help matters.

The overall building blocks of the private and hybrid cloud stack have now crystallized to a significant degree. The boundaries of these blocks aren’t hard-edged of course; there’s always overlap in the management space given that basic functions tend to come built-in even if they’re superseded at scale or for more complex requirements. But we’re at a point where we can describe the relationship of a cloud platform such as OpenStack to cloud management platforms (CMP)s like CloudForms that shouldn’t be too controversial.

Returning from OpenStack Summit in Hong Kong, I had some time on the fourteen-hour flight to think about Red Hat’s accomplishments within the OpenStack community, and more importantly, why they should matter to customers in the enterprise software space.

While I am gratified that Red Hat was again the top corporate contributor to the OpenStack Havana release, for me it goes beyond just the marketing value of being able to make that statement. It goes to the heart of the value of a subscription to our Red Hat Enterprise Linux OpenStack Platform, and the unique characteristics of open source projects versus commercial products.

Disaster Recovery Enablement in OpenStack

by Sean Cohen — November 26, 2013

In my previous blog post, I have shared the vision of Disaster Recovery as a Service for OpenStack (DraaS) as an umbrella topic that describes what needs to be done to protect workloads running in an OpenStack cloud from a large scale disaster.

Last week we shared this vision in several sessions at the OpenStack summit. While OpenStack attendees were dealing with infrastructure Disaster Recovery topics in Hong Kong, the strongest tropical cyclone in recorded history “Typhoon Haiyan” also known as Typhoon Yolanda, devastated multiple coastal cities in the Philippines and took the lives of tens of thousands of people with millions evacuated. The storm destroyed complete cities, villages, airports, roads, power and communications infrastructures.

If there’s one thing that history has not only taught us, but also keeps on teaching us every year, is that catastrophic events do happen and that if we don’t invest in preventative measures now, we will pay a hefty price later.

OpenStack Summit, Hong Kong 2013: A point of view from the PaaS perspective

by Diane Mueller, Principal Product Marketing Manager, Red Hat — November 21, 2013

Putting the PaaS in OpenStack (Platform as a Service)

For OpenShifters and PaaS aficionados in general, the Summit was all about cross community collaboration. As a PaaS, OpenShift touches on a lot of different OpenStack projects and related communities: Heat, Neutron, Nova, Docker, and now Solum to name a few. It’s important that we not only understand these projects, but participate actively in their design and development process.

As the OpenShift Origin Community Manager, and a huge fan of OpenStack, I was thrilled to get to attend the Hong Kong Summit, to chair the “Apps on OpenStack” track, participate in a panel on Why Enterprise Developers Should Care about OpenStack with such industry luminaries as Lew Tucker (Cisco), Chris Ferris (IBM), & Adrian Otto (Rackspace) and then moderate the closing panel on PaaS with participation from OpenShift, Docker, & Solum communities.
