Before we get to carried away with the cloud computing dream lets talk about
the fundamental challenges in the network (manual labor and kludge) that may
have a substantial impact on the shape of cloud computing, at least in the
Newspapers were originally fed on presses manually one sheet at a time.
Telephones were once connected via legions of operators connecting callers
(one at a time) with cables and plugs; and today computer networks are still
managed by legions of manual administrators who configure network appliances
and manage IP addresses as endpoints are added or moved or networks are
acquired. Yet can cloud computing really take that pain away?
How cloud evolves will be partly driven by technical limitations and partly
by business case economics; and the way in which cloud is adopted may have a
significant impact on the market caps of a hos... (more)
Whether you’re a small business considering cloud services or an enterprise
contemplating public or private cloud services, it pays to understand some of
the technical challenges and players likely to have a significant impact on
the availability, security and costs of those services. Cloud computing is a
game changer, and it may also pay to know who could win or lose as IT
services are decoupled from specialized hardware in specific locations.
Don’t let the endless list of companies proclaiming cloud leadership
confuse you that the world has already embraced cloud; there is a v... (more)
Recent attacks on outsourced DNS have caused extended outages for major
organizations, making them unreachable on the Internet and costing millions
in lost revenue and customer goodwill. All of these organizations,
including such notable companies Amazon.com, have one thing in common: they
outsource hosting of their external DNS. Is this a good idea?
Disclosure: I work for Infoblox, a vendor who offers a DNS appliance. Even
worse, I’m in the marketing department. Yet hear me out as I think I am
asking a valid question of an industry poised to outsource more IT services
A series of blogs began a speculation about the impact of virtualization on
the network. It’s certainly fair to suggest that the network has had
little impact on first stage VLAN virtualization, or virtualization-lite.
The real question, however, is whether or not virtualization (or VMotion
specifically) will stay contained within ever denser VLANS. F5 Networks
Today virtualization is creating new demands for another tech disruption.
Perhaps the first shots in this revolution were fired last week at an all day
working session of networking legends and "Young Turks" at the SRI
Infrastructure 2.0 meeting. Time will tell, but the level of interest and
discussion was exhilarating and timely. Vint Cerf, Bob Grossman and Dan
Lynch did an incredible job setting up the session with the help of SRI.
Virtualization Demands will drive the next Network Revolution
My take on why we met: Because of the spread of virtualization the IT
industry is al... (more)
