NSX Layer 2 VPN: Migrating workloads between Datacentres

Selecting a migration strategy

As a consultant within the NSX PSO practice, one of the conversations that comes up with customers often is how NSX enables migration from a legacy datacentre to an NSX managed datacentre. This was the case with a customer recently who were looking to move out of a datacentre that was scheduled to be decommissioned. The problem was that the customer workloads needed to be migrated to a Logical Switch within the new datacentre without changing IP addressing, and with minimal downtime.

There are four approaches available to us with NSX for vSphere that might help solve this problem:

  • Universal Logical Switching – we could deploy NSX to the remote site and extend L2 networks using Cross-vCenter NSX and Universal Logical Switches, then migrate the workload
  • Native L2 Bridging – within the same datacentre we could use the NSX Distributed Logical Router native functionality to create a Layer 2 Bridge between a VLAN and a Logical Switch
  • Hardware VTEP – using a compatible hardware device from a VMware Partner that acts as a VXLAN Tunnel Endpoint and can bridge between a VLAN and a Logical Switch
  • Layer 2 VPN – using an NSX managed Edge, or Continue reading

IDG Contributor Network: How to choose the right SD-WAN transport and why it matters

Businesses and their distributed enterprise locations grow more dependent on connected resources every day. That’s because employee and customer expectations and behaviors are evolving and having quick access to business information or constant connection to personal applications is changing the game for business networks. Every report I see indicates that our dependence on connected systems will continue to skyrocket. In fact, Cisco recently predicted that global IP traffic is set to nearly triple by 2021.To read this article in full, please click here

IDG Contributor Network: Digital transformation of cities: Creating smart and engaged communities with IoT

What makes a city a “smart city?” Some would argue that it has to do with the degree to which the city is staying abreast of technology advancements, but that is too one-dimensional. Smart cities require an integrated approach to IoT, connectivity, AI, distributed computing and other technologies.To truly capitalize on smart city technology, technologists must understand the immediate and long-term pain points for city governments; the procurement framework including budgetary and funding issues; and the overall bureaucratic and legislative processes.An integrated approach to technology implementation – cutting across all departments in the city – can help alleviate specific challenges such as parking management, traffic management, street lighting, energy consumption (and demand response), and public safety.To read this article in full, please click here

BrandPost: What Is an Autonomous Network?

Automation itself, and the idea that technologies could be self-provisioning, self-diagnosing, and self-healing, has been around for some time. But with advances in Artificial Intelligence (AI) and cloud technologies, such fanciful notions are quickly becoming realities.Nowadays, most of us use AI-enabled apps when we ask Apple’s Siri or Amazon’s Alexa for help with a task. And even streaming services like Netflix help us pick movies and TV shows using AI.WHITE PAPERIntroducing the Adaptive Network VisionTo read this article in full, please click here

The Server Market Booms, And It Could Last For A While

The general consensus, for as long as anyone can remember, is that there is an insatiable appetite for compute in the datacenter. Were it not for the constraints of budgets, for both the acquisition of iron, the facilities to house it, the electricity to power and cool it, and the people to manage it, it is safe to say that the installed base of servers worldwide would be much larger than it is.

But the world doesn’t work that way, and there are constraints. But thanks to ever more complex applications, ever richer media, and a burning desire to save …

Empowering Education for the Next Generation In Paraguay

Colegio Técnico National (CTN) of Asunción is one of the top schools in Paraguay offering the technical baccalaureate. It was created by the country’s Ministry of Education and Science in 1980. The school is attended by more than 1,500 students from the capital city and from nearby towns like Luque, Fernando de la Mora, San Lorenzo, Lambaré, and Capiatá.

As with most of Paraguayan state schools, the CTN does not have the right infrastructure for an appropriate development of modern education. The little equipment owned by the CTN, donated more than 25 years ago by private or charitable institutions, are today too obsolete. Classes do not have any type of interactive material due to the lack of an Internet connection, equipped laboratories, and modern computers. A new project lead by the Paraguay Chapter and supported by the Internet Society Beyond the Net Funding Programme will provide the school with Internet access and set up a high-tech electronics lab to ensure a quality environment for the development of innovative solutions based on robotics, automation, e-learning systems, and the Internet of Things. 250 students will be trained in the use of online tools. ReVa , a virtual library, will be available Continue reading

Companies ready to spend on IT hardware again

In-house IT hardware spending has been on hold thanks to executives flip-flopping on whether to move to cloud computing. It hasn't been because they've actually shifted to cloud services.The problem has been merely inertia caused in companies by "decision-making around the cloud," says Morgan Stanley in a new financial research note published this week. The financial services firm suggests that once enterprises complete their cloud assessments, their checkbooks will open once more.Also read: Top 10 data center predictions: IDC In fact, Morgan Stanley, which advises people on industry investments, says investors could see double-digit earnings growth from the IT hardware sector in 2018.

Ansible Tower Feature Spotlight: Instance Groups and Isolated Nodes

RH-Ansible-Tower-Spotlight

As we continue to improve Red Hat Ansible Tower, we’ve focused on allowing you to automate in more flexible ways, no matter your deployment scenario. As part of this, we’ve introduced two new features: Instance Groups and Isolated Nodes. These new features allow you to use Ansible Tower automation more flexibly in ways that match both the structure of your organization and your infrastructure.

Instance Groups

What is an instance group?

Ansible introduced Clusters in Ansible Tower 3.1. Tower Clusters allow you to add capacity to your Ansible Tower environment - the more nodes in your Tower Cluster, the more job execution capacity you have. If you have to run many jobs simultaneously, adding more nodes to the cluster lets you run them all without queueing.

However, this just gives you an additional mass of capacity. If you just have one group using a Tower instance, that may be enough. But we know that many Ansible Tower instances are shared among teams, groups, and organizations that may have different uses for their automation.

That’s why, in Ansible Tower 3.2,  we created Instance Groups.

An Ansible Tower Instance group is a set of cluster nodes dedicated for a particular purpose. Continue reading

NetDevOpEd: Demand more from your vendors

I was at the London Network Automation meetup this past week. London has a great community of network engineers that are eager to improve their current skill set and make their work lives easier. This meetup was geared towards learning new technologies around automation in the networking industry. There were talks about new ways to implement various existing automation tools, as well as real world discussions around how automation was implemented in the industry.

One common theme I experienced was how eager all network engineers are to open the scripts and code they write to administer their network devices. The sense of community and camaraderie amongst peers in this industry is one of the reasons I really enjoy working in this field. This is a real change in the industry. Even one year ago, the majority of network engineers did not have accounts on github or gitlab. Now, all these same network engineers exchange github and gitlab accounts like business cards. I couldn’t be happier with the direction this industry has taken.

However, I also couldn’t help but think about the irony of this situation. These creative and intelligent engineers are creating innovative scripts to shoehorn solutions into closed systems. Continue reading
