All the dire predictions for the demise of cloud computing that came with yesterday’s GMail downtime were, to be honest, kinda comical. I mean, after all, its not like my Windows laptop ever needs rebooting or the Exchange server ever goes off-line.However, for cooler heads, it does bring up a good question: what are reasonable availability requirements for a cloud based app? Should they be any different (higher or lower) than for an app sitting on a server in your data center. Read More »
I recently read the opinion of the CEO from one of our competitors that FCoE is too costly and that the demand for convergence in the data center is slowing. It is hard to argue that worsening economic conditions might affect customer’s spending plans in the future.However, history has shown that network convergence saves money, both in capital and operational expenditures. Whether it was convergence of WAN technologies in the 1980s that led to the dominance of TCP/IP as the standard protocol for the Internet or the convergence of numerous LAN technologies to Ethernet in the 1990s that enabled the creation of hundreds of new products that have the now-ubiqutous RJ45 Ethernet jack.This past decade has been no different. The convergence of voice, video, and data networks has created a completely new industry and lowered the cost of communications for millions across the world. From Skype to Vonage to Telepresence, none would be possible without network convergence.So as we look forward to a new decade, why would we not expect data center networks to follow a similar path? And why would a certain CEO downplay convergence when he just closed a major acquisition that enables him to capitalize on it? Perhaps history is already repeating itself and he finds himself behind like many other competitors that clung to their legacy technologies a bit too long.If you’re curious about how FCoE and data center network convergence could save you money, check out our online calculator and plug in your real-world numbers and see if it makes sense for you.Also, be sure to check out this recent article from the FCIA that makes the case for FCoE.
Last week we discussed the role of the lowly plumber in building the Dutch country of the Netherlands, reclaiming land masses from the sea, and ensuring that the hardy Dutch traders had a port to call home. It is amazing that infrastructure, designed hundreds of years ago, can still be so valuable today if you have the right architectural vision and scalable engineering approach that turns the vision into a reality.My good friend Silvano Gai commented on this post wanting to discuss the plumbing value that was delivered in the great Roman aqueducts, some built two millennia ago that still serve the city of Roma today! Silvano, a Cisco Fellow and great technology architect, must also be prescient, because today’s installment of this series is about the aqueduct.The Roman aqueducts are certainly the most notable, and aqueducts have been particularly associated with Roman engineering. Aqueducts have been in use for thousands of years -- in the 7th century BC the Assyrians built a 50-mile long aqueduct to carry water across a valley to their capital of Nineveh. The ability to carry water, vital for agrarian society, from a source such as a river, well, stream, spring, et cetera to the location where you want to grow a population center created the first utility.City growth was dependent then, and still is today, on available clean water. The cultural shift from hunter-gatherer to agrarian societies was amplified by the engineering feat of irrigation, compounded again by the distance you were able to transport this vital resource.In essence the value of a utility is amplified or compounded by the distance you can effectively distribute the resource the utility provides. In the city of Rome the aqueducts totaled over 260 miles and set a standard of engineering that was not surpassed for more than a thousand years. A network of aqueducts built an area of seven hills into a metropolis that was the capital of an empire, and the most cultured city of its time. This network that carried water from its source to the client in Rome enabled Rome to support a population of 1,000,000 people in 44 BC to 120 AD -- a number not again seen in Rome until the mid 1930s.Some myopic companies readily dismiss the value of plumbing -- but just like the Dutch owe their land to good plumbing -- we can all look to the golden age of Rome, and to the acceleration of a shift from hunter-gatherer to agrarian societies and thank the lowly plumber for ensuring the world’s first utility was available to create the masses that created the civilizations we know, and many significant cultural, religious, and political icons.dg
So, I am a big picture kinda guy, for better or for worse, and, while there are a number of really smart folks working on the plumbing behind cloud computing, from a go-to-market perspective, I have been wondering about what needs to happen to cross that tipping point. Read More »
Recently an alliance partner of Cisco’s lashed out at an honorable profession, that of the plumber. He was upset because the architect and project manager mis-managed the scope of work and he had to have the plumber install a special faucet in a custom home. Following this there was some diatribe about not wanting your plumber to design your home because you’d get charged high prices and you should instead buy into an architecture that encourages everything to be delivered by one conglomerate.Interesting argument -- I’ve heard it before. I’ve made it myself sometimes.I try to not normally call companies out by name in my blog posts -- I did it once and had several valued investors counsel me that this did not reflect well on Cisco, nor on myself. So I am not going to lash out, and am not going to engage in a debate. Instead- I’d like to make this a multi-part blog and today talk about Amsterdam.Yes- Amsterdam.To quote the British- “God made the world, but the Dutch made Holland.”We often think of plumbers as people who toil away steering water in and out of our homes, ensuring faucets don’t leak, and toilets don’t have ‘feedback’. We sometimes forget that plumbers actually engage in about anything to do with pulling of piping -- whether carrying natural gas, or liquids, or even the conduit I ran to put some Ethernet cables in. A leak- especially of something like natural gas, can have a rather high impact result, so we entrust these plumbers with the integrity of our homes, and in many cases our very lives. However, here in America we do sometimes take this honorable profession for granted. In Amsterdam however, the entire city exists because of good plumbing. In the Netherlands 50% of the land exists below sea level. 60% of the population lives below sea level, and 70% of the GDP is produced below sea level. The Dutch design not for the 100 year flood like most US cities, the Dutch design coastal areas for the 10,000 year flood level -- because they have to in order to live. The hydro-aware Dutch have executed on massive hydro-engineering projects in the estuaries of rivers like the Rhine, Meuse, and Scheldt called the ‘Delta Works‘ and another project called the Zuiderzee (fun to say, hard to spell) works. The American Society of Civil Engineers has declared the Delta Works to be one of the Seven Wonders of the Modern World! The entire city of Amsterdam -- which got its name from the Dam on the River Amstel -- or Amstel Dam has a canal system, that is the result of conscious city planning. Three for residential development, one for defense and all terminating in the IJ Bay.This conscious architecture -- based on a knowledge and experience with hydrodynamics -- allowed structures built in the 1600s to exist below sea-level for hundreds of years and still be valued infrastructure today.Is it all plumbing? No. But is ‘plumbing’ in balance with the rest of the infrastructure, that works as a system, to preserve the Dutch way of life and allow them to reclaim 50% of the land-mass of their country from the sea? Yes!Similarly I am not claiming network pre-eminence, nor plumbing pre-eminence. Unified Computing doesn’t do that either. We are saying that systems need to be built in balance, and when you take an architectural approach, you can reduce costs, extend life-cycles, and simplify operations. Not to mention -- you won’t miss the occasional faucet because the simpler the system is, the easier it is to install and manage.dg
