Physical Networks in the Virtualized Networking World

[This post was co-authored by VMware's Bruce Davie and Ken Duda from Arista Networks, and originally appeared on Network Heresy]

Almost a year ago, we wrote a first post about our efforts to build virtual networks that span both virtual and physical resources. As we’ve moved beyond the first proofs of concept to customer trials for our combined solution, this post serves to provide an update on where we see the interaction between virtual and physical worlds heading.

Our overall approach to connecting physical and virtual resources can be viewed in two main categories:

  • terminating the overlay on physical devices, such as top-of-rack switches, routers, appliances, etc.
  • managing interactions between the overlay and the physical devices that provide the underlay.

The latter topic is something we’ve addressed in some other recent posts (herehere and here) — in this blog we’ll focus more on how we deal with physical devices at the edge of the overlay. Continue reading

Getting Started with VMware NSX Part II – Building Virtual Networks

In the previous post we took a look at the simplicity of deploying VMware NSX into a new or existing VMware environment. This post looks to develop upon our existing infrastructure and build out a three-tier application with a Web, App and Database tier.

Application Topology

This application displayed above highlights what this blog seeks to build out. Note that there are three logical network segments – Web, App, DB and Uplink (Transport) – routing functionality provided by the Logical Distributed Router and an NSX Edge Services Gateway that is used to connect the logical network topology to the physical infrastructure.

Geneve, VXLAN, and Network Virtualization Encapsulations

In this post, Bruce Davie and T. Sridhar of VMware’s Networking and Security Business Unit take a look at a proposed a new encapsulation protocol that would standardize how traffic is tunneled over the physical infrastructure by network overlay software.

++++

For as long as we’ve been doing Network Virtualization, there has been debate about how best to encapsulate the data. As we pointed out in an earlier post, it’s entirely reasonable for multiple encapsulations (e.g. VXLAN and STT) to co-exist in a single network. With the recent publication of “Geneve”, a new proposed encapsulation co-authored by VMware, Microsoft, Red Hat and Intel, we thought it would be helpful to clarify a few points regarding encapsulation for network virtualization. First, with all the investment made by us and our partners in developing support for VXLAN (described here), we very much intend to continue supporting VXLAN — indeed, we’ll be enhancing our VXLAN capabilities. Second, we want to explain why we believe Geneve is a necessary and useful addition to the network virtualization landscape.

Micro-Segmentation: VMware NSX’s Killer Use Case

The advantages a software-defined data center, using network virtualization as a core underpinning, include service delivery speed, operational efficiency, reduced hardware dependency and lower cost. However, by far the most popular use case by customers thus far has been the use of NSX for network microsegmentation. Why? Because perimeter-centric network security has proven insufficient, and micro-segmentation has to date been operationally and economically infeasible. With NSX, security teams, in partnership with their network and virtualization teams, are benefiting from network micro-segmentation to begin to transform their data center security architecture. Then read the VMware SDDC Micro-Segmentation White Paper.

Getting Started with VMware NSX Part I – Preparation

This short series will focus on how virtualization administrators and network engineers alike can easily and efficiently deploy VMware NSX and network virtualization into their existing environments. From the simple and seamless installation, building your first virtual network to management and administration of an NSX environment, this series will highlight how easy it is to gain the benefits of network function virtualization.

Integrating NSX Manager into vCenter

Integration of the NSX manager into vCenter is the first task to be undertaken. NSX manager helps create a management plane for the NSX environment. When this is connected it will provide the Networking and Security plugin. It exposes a RESTful API for consumption by a customer or a cloud management platform. Such examples of those that can integrate with this API are vCloud Automation Center or OpenStack. Log into the NSX manager web interface with the credentials you specified during installation.

VMware NSX Runs Great on VCE Vblock Systems

Vblock SystemsLast week at EMC World in Las Vegas, one of the industry’s best offerings in converged infrastructure was on display. The adoption of converged infrastructure is becoming increasingly common in many organizations. In fact, research estimates that the total addressable market for converged infrastructure will reach $402B by 2017. Companies are taking advantage of converged infrastructure to accelerate cloud and software-defined data center deployments. Converged infrastructure is used by IT organizations to reduce provisioning times, centralize the management of IT resources, and increase resource utilization rates – resulting in lower costs. These objectives are enabled by the creation of pools of compute, storage and networking resources that can be shared by multiple applications and managed in a collective manner using policy driven processes.

Juniper and VMware: Collaborating to Enable The Software-Defined Data Center

The need for businesses to enhance the efficiency of IT and increase application agility is overwhelming. Embracing operational models such as cloud computing helps, but in order to fully leverage these new models companies must explore new ways of handling network connectivity. Network virtualization solutions such as VMware NSX provide an answer for the new cloud-centric networking models. As with any technology, though, network virtualization doesn’t solve some existing challenges by itself: consistent, efficient performance for business-critical applications that span virtual and physical worlds; correlated and integrated management; and enhancing data sharing between the network virtualization solution and the underlying physical network are all critical elements to successful cloud deployments. To address these challenges, we are pleased to announce that Juniper and VMware are expanding our partnership to help our joint customers achieve better application agility for their cloud environments.

Guest Post – When Pets Meet Cattle: OpenStack and VMware, Part 1

VMware is the industry’s leading enterprise virtualization software company. So it’s not OpenStack Logosurprising that one of the most common questions asked by enterprises considering OpenStack is: “How does OpenStack integrate with VMware vSphere and VMware NSX?” In November 2013, Mirantis and VMware set forth plans to work together on integrating Mirantis OpenStack with vSphere and NSX. Now, as a result of our collaboration, we have built what we believe to be the easiest way to configure OpenStack for a VMware environment. And we’ve scheduled a webcast to do some show and tell about how the technologies work together. You can register for the webinar here.

And in case you were wondering about the headline of this post, it was taken from a blog post written by our friend Nick Chase over at Mirantis.  Take a read of his post here.

The Goldilocks Zone: Security In The Software-Defined Data Center Era

Last week, we spoke at the RSA Conference about a new concept in security – the Goldilocks zone.  With the help of Art Coviello, Executive Chairman of RSA, Chris Young, senior vice president and GM of Cisco’s Security business unit, and Lee Klarich, senior vice president of product management from Palo Alto Networks, we departed from the typical discussions about new controls or the latest threats.  We took the opportunity to lay out what we believe is a fundamental architectural issue holding back substantial progress in cyber security, and how virtualization may just provide the answer. The growing use of virtualization and the move towards software-defined data centers enable huge benefits in speed, scalability and agility; those benefits are undeniable. It may turn out, however, that one of virtualization’s biggest benefits is security. Continue reading
