When most people think of digital businesses, names like Uber, Tesla and AirBnb come to mind. These companies were born in the digital era and have rapidly disrupted their markets.

VMware’s brand, install base and cult-like following
from its engineers give it a real shot at being a
hybrid cloud enabler, but it needs to work faster

I’ve heard some people say public clouds are a lot like the Eagles’ Hotel California—“you can check out any time you like, but you can never leave.” Indeed, many customers I’ve talked to about their use of public cloud services say once they start using a cloud service, they’re locked into that specific provider with no ability to move data or workloads from cloud to cloud.

To hear vendors tell it, SD-WAN technology is the
panacea to all network woes, but that doesn’t
mean you should rush into a deployment.

The software-defined WAN, or SD-WAN, topic is fascinating, especially when considering that the networking industry has been talking about WAN transformation for decades. (Thinking back to my days as a network engineer in the ’90s, I can recall discussing the need to migrate away from the inflexible hub-and- spoke architecture of the time — and that is still the norm today!) The underlying technology has evolved from frame-relay to ATM and now MPLS, but the fundamental architecture has remained the same.

Why so much talk over the years? What’s wrong with WAN design? Well, that’s like asking what’s wrong with reality TV — the list is far too long for me to go into all the points. But I can easily pinpoint the main issues of legacy WANs: They are highly inflexible, inefficient, and expensive to run.

The traditional WAN uses “active-passive” connections; the backup link is only active when the primary connection fails, meaning companies pay for bandwidth they aren’t using. This would be like connecting two cities with multiple roads but only allowing traffic to use secondary roads if the primary road is unavailable. Laughable, but it’s the norm with WANs.

Cisco well positioned to dominate cybersecurity market

The IT security market is certainly an interesting one, as it’s so big and so fragmented. Forbes posted a story at the end of last year stating the market is at $75 billion, with it expected to reach $170 billion by 2020. Every business and technology leader I talk to tells me how important security is, so I have no reason to doubt that $170 billion number.
