How it works: The basic tech behind the Internet

We all use the Internet, but few of us have an understanding of the fundamentals that propel it

How to pick the provider for a solid Ethernet WAN

Not all Ethernet-based WAN circuits are created equal; be sure to ask these questions when shopping for a carrier

What you need to know to build a solid Ethernet WAN

Sourcing solid network connectivity, such as for linking a pair of data centers, isn't always as straightforward as it might seem

Treat a cloud deployment as you would a home remodel

Cost, reliability, and security are obvious, but control and responsibility are often overlooked in choosing cloud services

The software licensing gotchas in the cloud

Some software vendors have embraced virtualization and the cloud, but others impose defensive licenses that serve no one

Here's why you really need SDN

Claims that software-defined networking can't scale in performance divert attention from SDN's huge benefit: flexibility

The conflicted rise of software-defined networking

Some vendors crippled their SDN offerings to protect their hardware profits, but smarter providers are switching now

Beyond backup: 5 other needs for World Backup Day

World Backup Day is a great reminder to make and test backups -- but what else might you be overlooking?

The impossible enterprise data security challenge

Securely deleting data in a personal context is hard enough, but it's far more complicated when enterprise storage is involved

Deleting data is the critical step you're likely doing wrong

Whether at home or in the data center, chances are your deleted data is easily available to others

Bad apples threaten small-business cloud adoption

Cloud providers often trade transparency for simplicity -- perhaps at the ultimate cost of their customers' trust

4 free tools to simulate a cloud connection

Linux-based WAN emulation tools can help you decide whether your planned cloud migration is the right move

Simulate access to the cloud before you commit

If you can't get a direct connection to the cloud, estimating user experience before migrating to the cloud is a critical task

Why recover from disaster when you can avoid it?

Sidestepping technology disasters is much easier -- and affordable -- now for businesses large and small

When WAN optimization really boosts network performance

As more and more data moves across WANs and into the cloud, making the most of your WAN connections is key

All IT pros need to understand TCP windowing

High-bandwidth replication over long distances, whether to a hot site or the cloud, requires a solid grasp of TCP to steer clear of bottlenecks

Data center power maxed out? Three-phase power to the rescue!

As load densities grow, three-phase power is becoming more and more prevalent in data centers of all shapes and sizes

The challenges of disaster recovery as a service

Backing up your data and running your systems in the cloud is attractive -- but likely to fail if you don't treat it like a physical warm-site backup

Data center planning: Surprising tools of the trade

Some skills required to be an excellent engineer might seem to have very little to do with actual engineering: Excel and Visio

The cloud isn't always cheaper -- and that's OK

Although the cloud is occasionally less expensive than on-premise deployment, focusing on cost alone misses the point
