We’ve been continuously developing methodologies for testing NFV and the cloud. Importantly, we have learned that test tools on their own are insufficient – what is required is an entire test solution, including expertise. For example, with C-RAN NFVi testing, one of the key elements depicted in the Technical Report, multiple test tools were used together, including tools sourced from Spirent and open source communities, as well as custom hardware and software tools. The combination of these various tool sets and specialized expertise enabled Spirent to deliver testing services to our service provider customers.

The demands for increased bandwidth in the data center are driving the creation of a new generation of data center switch platforms. These platforms, whether they are top-of-rack (ToR) or aggregation switches, are designed to support hundreds of gigabits/sec per slot—even terabits.

As Nemertes Research, voke’s ITO (Infrastructure Test Optimization), and Gartner research notes, and numerous other sources observe, implementation of IT initiatives such as data center network design, consolidation, and virtualization represent significant infrastructure and budget commitments that carry considerable risk.

A diverse array of component devices and applications in a unified architecture may cause network failure.

While individual devices and applications may work as planned, the complexity of an entire network, however, with configurations and associated firmware out of synch, can create a critical potential vulnerability that must be tested for defects that can bring down your network.

Simply put, the network failure threshold is the point at which your network breaks under real-world applications and user bandwidth. So is it better to know that before or after you launch your IT initiative?

To put it another way, from Nemertes Research’s perspective (from their classic issue paper Strategic IT Initiatives need Strategic Testing): “Without proper testing, such strategic initiative can fail with serious unforeseen consequences, including significant hard dollar and opportunity costs.” They also observed the gains expected from an IT initiative can be minimized or erased if the testing is not implemented before an initiative goes live.

As is the case with all marketing collateral, a company puts the best face on the product they want you to buy. In network equipment, part of that includes stating the capabilities of device, backed up by testing against particular requirements. While the device will likely perform exactly as described in the environment established by the vendor, how it performs in your network with your devices and your requirements is an entirely different proposition. “Results may vary.” Indeed.

The crucial nature of testing the success of any data center initiative is widely recognized, but all testing is not created equal. Proper testing is required and is a critical element of ensuring this success. The set of industry best-practices described below were identified and defined after numerous data center testing engagements, across lines of business and around the globe, by Spirent’s team of Professional Services engineers.

According to Network Computing and the Meta Group, the hourly cost of an hour of downtime ranges from $90 thousand for media to $6.48 million for a brokerage service, with telecom hitting in the middle at $2 million.* You don’t have to look far to find dramatic examples of the consequences of inadequate testing, or perhaps no testing at all.

At blitz.io, for a while there, we were only relying on CouchDB clusters as the primary NoSQL database with some in-memory caching. As we grow (rapidly) and scale out, there are aspects of what we collect and store that are transient and real-time. While CouchDB is awesome for the map/reduce, replication and incremental view indexes, the real-time queues (emails, counters, stats, etc) natural lend themselves to, yup, redis. We are in the process of rolling out geo-located redis instances as part...

This is a repost of my Atlassian’s guest blog, announcing a Bamboo plugin for blitz.io. The pig of a problem We all know what happens when your app performs like a pig. You lose users, customers and revenue. Your app is slow, the failing pigs don’t amuse your customers and you hear about it as the trending topic on Twitter. In most cases you don’t even know that it’s slow until you push the app into production, multiple times a day. How can you identify performance bo...

Okay, not the greatest, ground-breaking, coolest, earth-shattering feature ever. Let’s just get that out of the way. But, in the process of troubleshooting various latency issues for our customers, we found ourselves logging on to various EC2 instances of blitz.io to run traceroutes to our users sites/apps to diagnose problems. We are developers, hanging out in TextMate, vim and our terminals and the ability to take a local Unix command and run it remotely while staying in our zone (s...

Video and P2P Rule! The traffic making up today’s networks is in a rapid state of flux. Just last week Sandvine, in their Spring 2011 Global Phenomena Report, noted that real-time entertainment continues to increase, and within North America represents almost 50% of peak fixed access traffic (much of this of course is due to Netflix). P2P traffic also continues to carve out a sizeable piece of the pie at around 20%. The rest is a mix of voice, business apps, games, Facebook and chat. Wha...

There’s been a lot of debate recently about the impact of video apps on the network. According to Nielsen, Netflix alone now accounts for 20% of downstream traffic during peak times in the United States. In a previous blog Kowsik explained the behind-the-scenes interactions that are happening unbeknownst to you when you watch a Netflix movie. So that got us thinking – are all the popular video apps as network-intensive as Netflix? Are some video apps more user-friendly with their ban...

I’ve been in the testing business for many years now and I’ve come across a lot of grandiose claims by test tool vendors with regards to features and capabilities that just sound too good to be true. And in many cases, they are. When it comes to today’s world of smartphones and tablets and the explosive growth of web and mobile applications, it’s mind-blowing to see the sheer quantity of apps out there. If you look at the number of apps available today on just three of t...

This week there’s been much talk about NoOps with posts from @adriano, @allspaw and @krishnan, to name a few. It all started with this infographic from @appfog. The challenge is that the combination of the words No and Ops is wide open for [mis]-interpretation. Somebody Else’s Problem I think what we are witnessing is rapid emergence of services that started with the infrastructure (storage, compute, network) and rapidly moving up the application stack. PaaS, of course,...
