We all know the future of enterprises is in flux with the consolidation or demise of Avaya/Nortel, Brocade/Foundry, Force 10, H3C and BNT assets. This speaks to the major trend of enterprise applications migrating to the cloud, any cloud be it public, private or hybrid.

Interop ITX speaker says the key to a smooth transition is to start small with fresh hardware.
If you can’t beat the largest cloud players at economies of scale, the only option is to try to outrun them in performance, capabilities, or price.
While go head to head with Amazon, Google, Microsoft, or IBM on cloud infrastructure prices is a challenge, one way to gain an edge is by being the first to deliver bleeding-edge hardware to those users with emerging, high-value workloads.

Naturally as a growing startup, the technology we used to handle tens or hundreds of thousands of zones a few years ago became outdated over time, and couldn't keep up with the millions we have today. Last year we decided to replace two core elements of our DNS infrastructure: the part of our DNS server that answers authoritative queries and the data pipeline which takes changes made by our customers to DNS records and distributes them to our edge machines across the globe.
The rough architecture of the system can be seen above. We store customer DNS records and other origin server information in a central database, convert the Continue reading
Evgeny made an interesting observation while testing the NETCONF client on IOS XE 16.x (see also this comment on my blog):
The most interesting part: for unknown reason IOS-XE gives different answers about capabilities on ports 830 and 22.
Einar quickly explained the mysterious behavior:
