““I think it has a huge impact,” replied Mr. Heyman. “We did fullscale college recruiting for Foursquare for the first time this year, where we were trying to recruit a large number of grads….We gave them a choice [between San Francisco and New York] and a significant portion chose New York. There’s lots to do there, so being in New York has actually been a recruiting tool, and I expect that to only increase moving forward.””

“While it’s true that both Pinterest and Instagram are not making great advances in science and technology, that is more indicator of the easy power of today’s commodity environments rather than a sign of Silicon Valley’s lack of innovation. The numbers are so huge and the valuations are so high we naturally want some sort of fundamental technological revolution to underlie their growth. The revolution is more subtle. It really is just that easy to attain such growth these days, if you can execute on the right idea. Get used to it.”

“Pay for what you don’t use. A downside of the provisioned throughput model is you pay for the throughput you have reserved, not the traffic you have actually generated. From Amazon’s perspective they are reserving the capacity so in a sense you are using the capacity, but this is the same capacity planning issue that made the elastic nature of the cloud so attractive to begin with. How do you specify the correct throughput? If you underspecify you lose customers. If you over specify you lose money. And if your traffic is at all bursty you technically would have to reserve the peak usage, which is fiscal insanity. You can adjust your throughput reservation, but you can’t do it fast enough to meet a burst, and the drop notification mechanisms are clumsy, you get an email alert and then have to do the adjustment by hand.”

“VMware Cloud Infrastructure Suite is really more of a marketing term. Those of you know our products deeply know that they don’t fit this well together as they need to. Some of them have multiple databases, some don’t look the same, some install differently, and what I can’t stand that is Site Recovery Manager doesn’t currently work with vCloud Director. So, what we are basically able to say is that we created and acquired companies that led to a lot of individual products that don’t work well enough together yet.”

“On the other hand, if you know that you’re pretty solid under your current load but a 50% increase in usage has the potential for some degree of system failure, your error budget might not accommodate both the risky new features and the membership growth. And if your business pushes you to do both the risky new features and the growth risk? Make sure they know that your SLA may suffer as a consequence. When you know your goal SLA, and you know something is likely to reduce or violate it, that’s a strong signal that you should think carefully about the risks of the project. This can also be a useful negotiation tool when being pushed to implement a feature you don’t think is ready for prime time. When they say we need to release this new feature today, which means at least two hours of downtime that pushes you out of SLA, it becomes their job to get authorization from the CTO instead of your job to convince them why it is a bad idea.”

“What’s important here: CloudFront dynamic acceleration costs the same as static delivery. For US delivery, that starts at about $0.12/GB and goes down to below $0.02/GB for high volumes. That’s easily somewhere between one-half and one-tenth of the going rate for dynamic delivery. The delta is even greater if you look at a dynamic product like Akamai WAA (or its next generation, Terra Alta), where enterprise applications that might do all of a TB of delivery a month typically cost $6000 per app per month — whereas a TB of CloudFront delivery is $120. Akamai is pushing the envelope forward in feature development, and arguably those price points are so divergent that you’re talking about different markets, but low price points also expand a market to where lots of people can decide to do things, because it’s a totally different level of decision — to an enterprise, at that kind of price point, it might as well be free.”

Calvin: Fast Distributed Transactions for Partitioned Database Systems [pdf]:

“Calvin supports disk-based storage, scales near-linearly on
a cluster of commodity machines, and has no single point of failure. By replicating transaction inputs rather than effects, Calvin is
also able to support multiple consistency levels—including Paxosbased strong consistency across geographically distant replicas—at
no cost to transactional throughput.”

“Calvin, the researchers claim, can match Oracle’s 500,000 transaction-per-second performance running on commodity servers on Amazon EC2. The cost of the resources to run their benchmark was only $300. (Although, obviously, that doesn’t account for the cost of running the system continuously for years, potentially. Commodity physical hardware might be a better bet in the long term.)”

“In 2012, The Linux Foundation will introduce a new annual technical conference, CloudOpen, designed to provide a collaboration and education space to advance the open cloud. CloudOpen is a conference celebrating and exploring the open source projects, technologies and companies who make up the cloud. It’s built on a belief that open works: for users, for industry and for technology. CloudOpen brings together the open source projects, products and companies that are driving the cloud and big data ecosystems today, along with best practices from the world of traditional open source. This conference is about the future of computing and how users should ensure that their cloud solutions — technologies, data, and APIs — are truly open.”
