Palo Alto Networks at ONUG Spring 2019 and Understanding the Security Landscape for SD-WAN

With many organizations adopting a direct-to-internet networking strategy for their branch locations, there is considerable interest in how to architect the security. This is especially true if the organization is also adopting SD-WAN as part of their branch networking strategy. That’s because that SD-WAN can be architected in many different ways, and that can make security options hard to implement without making compromises. At a baseline, security at the branch should not be different than security at headquarters. There’s no reason why a person at…

Hybrid Cloud, Multicloud, and Containers. Oh, My.

You might have heard that multicloud is the future of IT. It would be more accurate to say it’s the present of IT. More than 80 percent of enterprises already have a multicloud strategy. But what is multicloud, exactly? As the name suggests, multicloud is an IT approach in which an organization uses multiple cloud services from more than one provider. Hybrid cloud versus multicloud Hybrid cloud and multicloud might sound like the same thing, but there is one crucial difference. With hybrid cloud, an…

Optionality: Realizing the Full Potential of Redundant Application Infrastructure

Modern traffic steering has evolved into a multi-dimensional optimization problem. From ensuring availability, minimizing latency, maximizing throughput, preventing flapping, and meeting CDN commits; we ask more from our infrastructure today than ever before. With so many competing interests, how do we guarantee an exceptional user experience while still achieving a diverse set of business goals? Redundancy is an essential first requirement in modern application architecture. Investing in redundancy means investing in drop-in replacements to be available in times of crisis. Back-up infrastructure prevents downtime for…

SDWAN 2.0: The Right Stuff for a Multi-Cloud World

When I started my career in networking  (longer ago than I care to admit), the industry was struggling with incompatible systems at the protocol and interface level. As a budding young engineer concerned with ordering a chaotic technosphere, the OSI model seemed like just the remedy. That was an era where innovation moved a lot more slowly. Today, when innovation is advancing at the pace of business, we need to use software and systems to innovate, just like we do with protocols. System APIs and…

Navigating Your Security Options with SD-WAN

SD-WAN opens up many security options to explore. For virtualized security, as more companies adopt SD-WAN technology to enhance the agility of their networking architecture, they must give strong consideration to how and where to apply security across the network. For example, retailers with a lot of store locations can benefit from virtualized SD-WAN and security. Companies that fit this model typically have key applications that run at a centralized data center. They use internet VPNs at the branches to connect back to the mothership…

Streaming Telemetry Has Arrived. Why You Should Care.

About 30 years ago, we began connecting devices such as routers, hubs, and printers to IP networks. That meant these resources went from being mostly housed in one location like a data center to spread all throughout an organization’s operations. IT and NetOps teams immediately recognized that they needed a standardized way to monitor and manage those devices remote. And Presto! the Simple Network Management Protocol (SNMP) was born. SNMP made it “simple” for network management systems to request and receive data from the ever-growing…

“AI for IT” Is Real and Gaining Momentum Quickly

I will be first to admit that marketing can sometimes get ahead of reality. It is our job to create a story that paints an appealing vision of the future, knowing that it may take a little while for engineering to actually “catch up”. And when multiple vendors start screaming the same buzzwords from the top of multiple different mountains, the line between product and PowerPoint can become a bit blurred and confusing. “AI for IT” is a perfect example of this. Customers want an…

Why Network Monitoring Doesn’t Stop with SD-WAN

Network teams often look to SD-WAN as a silver bullet for all of their management and monitoring needs, hoping these tools can help curtail the major pitfalls that are notorious for derailing enterprise cloud migration. But not every team’s path to the cloud is the same, especially as companies become increasingly distributed and rely on their network to keep remote teams connected. And while SD-WAN can help streamline management, most platforms leave out a lot of detail where monitoring is concerned. Sure, SD-WAN can help…

Autonomous Networks, Not Network Automation

In today’s fast-paced cloud environments, automation is required to effectively manage systems of any size. Often the goal is to do more with less, so operators can strive to look beyond what it takes to keep the lights on; this is the same for managing the network or system infrastructure. Even though network operators face similar pain points as those seen in compute environments, they have what seems like an inherent advantage in fewer pieces of equipment to manage. However, with the trend of building…

ONUG Academy Delivers Skills Needed for the Hybrid/Multi-Cloud Era

Over the past several years, the ONUG Community has been keenly focused on IT organization transformation. We know that most digital transformation projects’ success or failure are directly correlated to IT skills, culture and organizational design.  We have been keenly aware that many CEOs and their boards have shelved digital projects, thanks to the lack of confidence expressed by their CIOs that their IT organizations are not prepared. There is a massive industry skills gap in IT organizations to deliver good digital outcomes. Skills and…
