Network and data-center architects are evaluating network virtualization solutions to bring workload agility to their data-centers. This article (part 3 of a 3 part series) details how to setup fully-functional VMware NSX and Cisco Nexus 1000v deployment on Ravello to evaluate each of the solutions. Part 1 compares the architectural components of Cisco Nexus 1000v and VMware NSX, and Part 2 looks into the capabilities supported by of each.
With SDDC (Software Defined Data Center) gaining prominence, network architects, administrators and data-center experts in enterprises around the globe find themselves staring at the inevitable question – should I go for vSphere environment with Cisco Nexus 1000v or VMware’s NSX as the network virtualization solution that facilitates my SDDC? This article (part 2 of 3-part series) compares Cisco Nexus 1000v with VMware NSX from deployment model, components, multi-data-center support and network services perspective. Part 1 compares capabilities supported by Cisco Nexus 1000v and VMware NSX, and Part 3 walks through how to setup a fully functional environment of each on Ravello Networking Smart Labs (powered by nested virtualization and networking overlay).
Network virtualization brings many benefits to the table – reduced provisioning time, easier/cheaper network management, agility in bringing-up of sophisticated deployments to name a few. A large number of network and data-center architects around the globe are evaluating VMware NSX and Cisco Nexus 1000v to enable network virtualization in their data-centers. This article (part 1 of 3 part series) walks through the architectural elements of VMware NSX & Cisco Nexus 1000v, and explains how Ravello (powered by nested virtualization and networking overlay) can be used as a platform to run and deploy each of the solutions with a couple of clicks for evaluation during the decision-making process. Part 2 compares capabilities supported by Cisco Nexus 1000v and VMware NSX, and Part 3 walks through steps to create a Cisco Nexus 1000v & VMware NSX deployment on Ravello.
Public cloud is great. It brings to table agility, on-demand capacity, unlimited resources, global reach and most importantly ability to align costs with operational needs. More and more organizations are embracing cloud to augment their datacenter capacity or to move their existing workloads off their datacenters. As datacenter and network architects embark on this journey, they need to be aware that there are some inherent differences in the way networking works in an Amazon VPC when compared to datacenters – so that they can plan ahead.
This article details NFV orchestration using public cloud NFVI as a 4 part series. This post details setting up a fully functioning NFV orchestration with firewalling and load balancing services chaining, and comes with a fully-functional NFV service chaining topology with Juniper Contrail service chaining firewall and load-balancer services in a topology that you can access on Ravello and try out.
The OPNFV project is dedicated to delivering a standard reference architecture for the deployment of carrier-grade Network Function Virtualization (NFV) environments. Testing is critical to the success of the project and to the success of real-world deployments, as evidenced by the many test-related sub-projects of OPNFV. One of those subprojects, VSPERF, is dedicated to benchmarking one of the key NFV components: The virtual switch.
This article details NFV orchestration using public cloud NFVI as a 4 part series. This post in the series looks into how service orchestration using Juniper Contrail can help assist with multi-tenancy and workload mobility, and also increase service velocity through NFV orchestration and service chaining.
In this second part of a 4-post series around NFV orchestration we detail how NFV (Network Function Virtualization) can help alleviate multi-tenancy and network mobility challenges and increase service velocity (pace at which services can be rolled out) across enterprises and service providers.
Setup and operate your own OPNFV Architecture for dev, test, training using Ravello Systems on AWS and Google Cloud.
This article details NFV orchestration using public cloud NFVI as a 4 part series. This post looks into challenges traditional networks have with multi-tenancy and workload mobility. In the next, we’ll show how Network Function Virtualization (NFV) fits in and can increase service velocity.
Enterprises are looking to secure their network, web and applications against vulnerabilities – they are hiring ethical hackers to penetrate their infrastructure to discover holes. Public cloud (e.g. AWS or Google) is an excellent candidate to build pentesting environments to scale, but lacks some key functionality. Ravello’s Security Smart Lab on AWS and Google overcome these drawbacks, and enable creation of high fidelity production environment replicas that can be used for effective penetration testing.
Cumulus Networks provides a Linux based OS for data-center switches, and has seen a great adoption in the last year. Enterprises love Cumulus since existing Linux management, automation and monitoring tools work seamlessly with Cumulus switches – dramatically simplifying data-center…
Networking enthusiasts rejoice – we are proud to share that VyOS is now available on Ravello Repo. Using Ravello’s nested virtualization and networking overlay technology, it is now possible to run VyOS on AWS & Google cloud with Layer 2…
Network Function Virtualization has taken the networking world by storm. It brings to the table many benefits such as cost savings, network programmability and standardization to name a few.
Ravello with its nested virtualization, software defined networking overlay and an easy to use ‘drag and drop’ platform offers a quick way to set up these environments. With Ravello being a cloud based platform, it is available on-demand and opens up the opportunity to build sophisticated deployments without having to invest time and money to create a NFVI from scratch.
Brocade’s SDN Controller and OpenDaylight controller are excellent options for companies that are looking to bring virtual network services on OpenStack. In the past year, Brocade has made significant investments to improve the integration between OpenDaylight and Openstack – including…

Once upon a time all you needed to protect your network was a simple firewall. As the Internet adoption increased, the protection provided by firewalls was soon discovered to be inadequate to respond to the increased sophistication of today’s threats. Security vendors have responded with improved protection mechanisms pushing the inspection all the way up to the “content” (application layer). Today’s NGN Firewalls are equipped with the intelligence to detect and prevent intrusion attempts, identify malicious files, applications, users and devices.
Service Providers around the globe deploy MPLS networks using label-switched paths to improve quality of service (QoS) that meet specific SLAs that enterprises demand for traffic. This is a two-part post – Part 1 introduces MPLS constructs and Part 2 (this post) describes how to setup a fully-functional MPLS network using Ravello’s Network Smart Lab. Interested in playing with this 14 node Service Provider MPLS deployment – just add this blueprint from Ravello Repo.
