One of the major misconceptions around SD-WAN is that it requires a re-architecting of the network, and seeing the benefits will take anywhere from 6 – 24 months. It’s completely possible to have all the power of application-aware SD-WAN in as little as two months without re-architecting the network, and to start seeing digital ROI in less than 6 months. The secret key? It starts with understanding hybrid WAN architecture, and how it can bridge the gap between your current WAN and the capabilities you…
When it comes to cloud applications – and every business uses them – SaaS rules. CRM, ERP, HCM, UCaaS, productivity, and even desktops – these are just a few within the myriad of SaaS choices used by the workforce of today’s modern organization. What these apps have in common is that they’re beleaguered by a sub-optimal experience provided by a sub-optimal network. Long waits for Salesforce data to load, page timeouts while booking travel, or talking through a presentation and being two slides ahead of…
BGP protocol has allowed network operators to apply and enforce the most varied inter-AS routing policies during the past 30 years. It is amazing how this protocol efficiently sustained the ever-increasing number of subnets and AS’s, as well as the evolution of the Internet from a mostly hierarchical structure made of customers and providers to a structure where peering and IXPs become more important every day. Despite all its good qualities, BGP shows several vulnerabilities which, if exploited, can cause ripple effects all over the…
In my previous ONUG blog post Query Your Network like a Database, I talked about how companies are embracing Network Automation in order to become more agile. I described how Network Automation can be very powerful but frighteningly dangerous without a proper safety guard. I explained what the Forward Networks Network Query Engine is and how it can help in building a rock solid network verification solution. But now I’ll explain how customers can build a complete network automation and verification solution with Ansible and…
Moving critical applications and services to the cloud brings power and agility to IT teams who no longer have to worry about building and maintaining infrastructure. But it also brings risks because cloud computing introduces a solid dose of unpredictability due to the sheer complexity of the Internet and cloud connectivity. We are reminded of this reality on a reasonably regular basis when outages occur in the cloud or other service providers. On June 2nd between 12pm and 12:15pm PDT, ThousandEyes detected a network outage…
At ONUG Spring 2019 in Dallas, members of the Hybrid Multi-Cloud Steering Committee reported on the results of a survey of enterprise users in the ONUG Community about barriers to hybrid multi-cloud adoption. The survey, conducted prior to the conference by 451 Research, ranked the inhibitors preventing enterprises from proceeding with a hybrid cloud deployment: These are valuable data points for the steering committee in terms of setting overall objectives for the ONUG Working Groups, but what the survey did not attempt to do was…
Digital innovation is redefining networks to improve customer and worker experience, accelerate the development and delivery of critical applications, and gather and process data to more effectively meet modern customer demands. New cloud infrastructures and SaaS solutions, IoT devices, and highly mobile workers are all the result of this transformation. Completing this picture requires extending these applications and services to branch offices, remote retail locations, and distributed classrooms and campuses. Traditionally rigid WAN connections, such as MPLS, need to be replaced with solutions that enable…
Automation in networking is casting new implications on the way networks are engineered, structured, designed, coded, and even thought of. Let’s see if low-code and closed loop dovetail automation into intent-based networks. As the networking landscape transformed from a siloed, rigid, monolithic and slow beast; to a fast bird that can be accelerated with Software-based Networking (SDN) and intelligent networking hardware, the idea of Intent-Based Networking (IBN) started to seem more like a reality. This paradigm of networking – IBN- would be truly disruptive and…
Talk to cloud providers about interoperability, and they get an allergic reaction, a bad allergic reaction … one that comes on within milliseconds. I get their reasoning. The market is moving too fast, and creating standards will only slow down the pace of innovation. Or you’ll hear “we’ve invested so much in innovation, why should we give it away?” Or “we’re so far ahead of the market, opening it up will only erode our share that we risked capital and brand to gain.” It doesn’t…
You’re on a corporate web conferencing call using Zoom, Webex, Goto Meeting, BlueJeans, Google Talk, Skype, etc and all of a sudden it stops working. The complaints start to roll in, business is slowed, tempers flare and the first thing operational personnel think is, “what the heck, it was working fine yesterday!” Was there a configuration change, is a circuit down, is the wifi controller off-line, was there a change to the firewall, is the SaaS application down, are we experiencing a DDoS attack or …
