From the onslaught of SaaS, to the widespread adoption of cloud, to leveraging the Internet to connect stakeholders across the WAN, there are no lack of special projects that IT has to manage at any given time. In the midst of steering transformations like SD-WAN and DIA adoption, teams need to also execute on their day-to-day marching orders of ensuring...

Disbelief is a common theme in our demo process with potential customers. When we use AppNeta Performance Manager to show a customer their own data for a particular office, they almost immediately ask why the capacity metrics are low. If the customer is paying for 250 Mbps out of that office, why is AppNeta only showing them 46 Mbps? The...

There was a time when the consumerization of IT struck fear in the hearts of any network manager. It was easier to push back and deny or ignore iPhones in the workplace than to actually revamp the network to support them—not to mention prepare for the onslaught of cyber threats that came along with them. But that was years ago....

Last week, I presented Caching Up and Down the Stack at the Boston Web Performance meetup. It was great to get the chance to present to the 60+ people who came out for the talk. Unsurprisingly, many of the people there knew a lot about caching in all of the different levels I touched on, and some great conversation developed. I covered six of...

This past summer, I wrote about T1s and three best practices for WAN Performance. As I mentioned in that post, T1-class WAN services are a popular way to connect branch offices to corporate data centers and the Internet for voice and other application services. While the 1.54Mbps definition of a T1 hasn’t changed over time, it’s now common to see multiple T1...

Bandwidth is a coveted resource in most offices. Since businesses rely so heavily on the internet, it’s imperative that your organization has adequate bandwidth to support the day-to-day workload. Without it, businesses can come to a screeching halt. Every organization needs a different amount of bandwidth depending on its size and the type of applications that are running on its...

Healthcare practices today run on networked applications that connect remote users (hospitals, physicians, clinics) to centralized or hosted resources. Electronic Health Records (EHR), web-based clinical health programs, inter-site communication and online medical registries are all critically dependent on network and application performance. Any drop in bandwidth or increase in latency can make these applications unusable or inaccessible, potentially compromising patient...
