Troubleshoot like a BADaaS and Get More Sleep with Avi's Load Balancer

Any vendor will tell you they have detailed analytics and an intuitive interface (GUI). They'll state that certain tasks can be done in “just a few clicks”. Most vendors over-promise and under-deliver in this area, which is why we at Avi Networks took up the challenge of showing (not just telling) how much better the experience can be with our load balancer.

Guru’s Guide to Excel-ing as a Network Engineer

While it’s tempting to make fun of it, the reality is that Excel is a pretty good tool to consolidate the data from your network in one place, analyze it, generate reports, and much more. Unfortunately, importing data from network appliances into Excel is a laborious, manual process and keeping the data up-to-date is almost impossible.

One hundred and twenty-two years ago German physics professor Wilhelm Conrad Roentgen discovered the power of X-rays with the “X” signifying “unknown”. The hand on left on the image below is the first X-ray “radiograph” that Roentgen created of his wife’s hand in 1895. In today’s modern society it’s easy to take things for granted but prior to the invention of X-Ray machines, broken bones, tumors, or the location of shrapnel were all diagnosed by physical examination. Yikes! Exams involved guess-work, were prone to error, and were dangerous to the patient. I am grateful to live in today’s world of modern medicine where physicians have improved tools to diagnose and help treat illness and trauma without as much guesswork.

Application Performance Monitoring (APM) and Load Balancing

Imagine this scenario. It is a Wednesday morning and as the network administrator responsible for servicing business applications, you are processing a series of support tickets that arrived in the past few hours and the previous day. One of the high severity items on your plate this morning is from an application team that has been debugging poor performance of a business critical application. They have received complaints from end users and the line-of-business manager is concerned about potential revenue impacts. The application team has been frantically looking at their logs and haven’t quite pinned down the problem. They now believe it is an issue with the network and want your help finding the source of the problem. By the time the problem has been escalated to you it is already late and they want answers immediately. And just to add to the problem complexity, the issue has been happening sporadically for the last couple of weeks. What do you do?

Screaming Metrics | Application Performance Monitoring by Avi

Posted on Apr 12, 2016 6:30:00 AM

As Avi Networks set out to build the next generation of software load balancers, we wanted them to be optimized and smart.  An important aspect that we considered was to use multiple analyses to understand and automate critical decisions that are usually manual, and often made without enough data.

Software Load Balancers and Cloud Environments | Avi Networks

 The Hardware Load Balancer Brick Wall Last month at Networked Systems Design and Implementation (NSDI)  conference, Google lifted the covers off Maglev, their distributed network software load balancer (LB) [1]. Since 2008, Maglev has been handling traffic for core Google services like Search and Gmail. Not surprisingly, it's also the load balancer that powers Google Compute Engine and enables it to serve a million requests per sec without any cache pre-warming [2]. Impressive? Absolutely! If you have been following application delivery in the era of cloud, say over last 6 years, you would have noticed another significant announcement at Sigcomm ‘13 by the Microsoft Azure networking team. Azure runs critical services such as blob, table, and relational storage on Ananta [3], its home-grown cloud scale software load balancer on commodity x86, instead of running it on more traditional hardware load balancers. Both Google and Microsoft ran headlong into what can be best described as “the hardware LB brick wall”, albeit at different times and along different paths in their cloud evolution. For Google, it started circa 2008 when the traffic and flexibility needs for their exponentially growing services and applications went beyond the capability of hardware LBs. For Azure, it was circa 2011, when the exponential growth of their public cloud led to the realization that hardware LBs do not scale and forced them to build their own software variant. So, what is this “hardware LB brick wall” that these web-scale companies ran into?

SSL and DDoS Security Insights | One-Click Insights with Avi Networks

I recently read an interesting blog post on an ADC vendor’s site that demonstrates a Rube Goldberg approach to showing common SSL information. Now I won’t name names but I will admit that it inspired me to write a quick blog post to show the business-ready alternative to the science project approach!

Out of Sight, Out of Mind? With Security, That’s Out of Your Mind.

INTRODUCTION:  I’m pretty certain that whoever first uttered the phrase “anything easy isn't worth having” was no IT administrator. This certainty derives from the seemingly path-of-least-resistance attitude that many enterprises hold when it comes to enforcing stringent levels of encryption security for public infrastructure including their websites. We’ve previously blogged on the excuses many enterprises make for their lax encryption practices, but it’s worth examining what I believe is the primary culprit for this: lack of visibility and insights into their security profiles.

Application Delivery Webinar | Cisco and Avi Team Up

Achieving agility is a paramount importance for enterprise IT today and one key area many companies are turning to for this is deploying higher degrees of network automation. This has led to the rise of software-defined networking (SDN), which is designed to drive automation and programmability network-wide. Cisco, the undisputed leader in networking today, has seized on this important market transition with its unique, application-centric approach namely, appropriately enough, the Cisco Application Centric Infrastructure (ACI). Cisco ACI has seen significant traction spurring our joint (Cisco and Avi Networks) customers to request deeper levels of integration between our respective solutions.
