 “The edge will eat the cloud. And this is perhaps as important as the cloud computing trend ever was.”—Tom Bittman, Vice President and Distinguished Analyst at Gartner Research If you’re one of the many IT pros still finding your footing with cloud computing, this statement from Tom Bittman might sting a little. It sounds like you might be spending time...

What is a Path? A Path is the network connection from a source to a target, specifically measuring the maximum end to end performance achievable. For example a Path from our office here in Boston to the Salesforce.com instance we use (NA2) located outside of Chicago consists of 12 layer 3 network hops. We have a 100Mbps symmetric internet connection...

Ever wonder if your ISP is giving you the bandwidth you are paying for? Do you think your download speeds are different at different times of day? If so, you might want to detect and measure the rate limiting on your network. What is Rate Limiting? Network rate limiting is used to limit the amount of traffic on a network....

I don’t think I was alone June 21, 2012 when I went to check-in on Twitter during lunch and for some reason could not connect. Hmmm, how is that possible? The Twittersphere can’t actually be down…or can it? My office in Boston was also experiencing some network problems so I just assumed the Twitter issue was related to the Comcast...

2011 could be considered the year that network performance management “came of age.” In this past year, IT and network managers in organizations of all sizes and industry segments have become aware — if they weren’t already — that the performance of the network is the foundation of user experience and business success. Why was 2011 such a pivotal year...

Security is a well-known risk with cloud applications, but…what about bandwidth? More and more businesses are looking to cut costs and improve end customer experience by moving customer-facing applications, storage/backup solutions, and many other applications to distributed data centers in the cloud. If users experience performance or latency problems due to insufficient network bandwidth, such as slow, stalling or failed...

Every major wireless carrier is racing to deploy 4G branded mobile data services.  Although the mobile data user has been trained to lower his or her performance expectations, the wireless carriers are working hard to change that perception.  Can 4G wireless services support real time applications like voice and video for the mobile office of 1?  Can it replace more...

When it comes to online trading, network latency is everything – because delays are more costly in this industry than almost any other. The stock market doesn’t stand still while data is in transit, and the difference between a “fresh” price quote and one that’s a few milliseconds out of date can cost or earn brokers and their clients hundreds...

Raise your hand if an end user has complained of a slow file transfer? You can’t tell, but my hand is the highest. File Transfer Protocol (FTP) transfers have been around since the dawn of the civilization.  Not really, but it has been around for the duration of the internet. Point being, the FTP is everywhere. This made me think,...

We want to share a great use case recently submitted to the AppNeta’s Customer Testimonial Case Study Contest from the Liquor Distribution Branch of British Columbia (LDB). Check out their story below to learn how they resolved serious latency issues for remote site applications. Organization: In British Columbia, the Liquor Distribution Branch (LDB) is one of two branches of government responsible...

Are you considering moving business-critical applications like e-mail, financial management, backup/recovery and CRM to the cloud? Or maybe you’re already on your way? It’s clear that cloud computing has arrived, and businesses of all sizes are taking advantage of it even faster than initially predicted. Gartner rates it as the top strategic technology for 2011, and surveys from MarketBridge, IBM...

It is a sign of the times that I need to clearly define the term “cloud services” if I am going to use it as an entry point to this blog. And since I wouldn’t dare assert my position to be expert enough to properly define this term (any attempt would surely bog down this entire effort), I will turn...

As companies turn to the Cloud as a low cost, highly scalable and agile way to save on their infrastructure cost or to host new applications, a number of cloud performance testing and monitoring solutions are appearing. There are applications popping up to perform load testing against your cloud infrastructure, some of which are even developed and hosted by the...

We like to celebrate our history! Our legacy blog entries tell the AppNeta story from its inception as Apparent Networks. If you’re suffering from slow application performance, chances are you’re suffering from some degree of latency.  As everyone knows, each computer has its own performance limits.  With one too many applications, lag will result from the inability of the computer...

As applications evolve, so does the infrastructure that supports them.  In terms of network dependent applications, the applications of today are dramatically more performance sensitive than the ones of yesterday.  Voice over IP, video conferencing, and virtual desktop infrastructure all rely heavily on high bandwidth, low latency networks to perform without hiccups and service interruptions.  So how well does a...
