By Michael Strevens – Modern science has a whole lot going for it that Ancient Greek or Chinese science did not: advanced technologies for observation and measurement, fast and efﬁcient communication, and well-funded and dedicated institutions for research. It also has, many thinkers have supposed, a superior (if not always ﬂawlessly implemented) ideology, manifested in a concern for objectivity, openness to criticism, and a preference for regimented techniques for discovery, such as randomized, controlled experimentation. I want to add one more item to that list, the innovation that made modern science truly scientific: a certain, highly strategic irrationality.
‘Experiment is the sole judge of scientific “truth”,’ declared the physicist Richard Feynman in 1963. ‘All I’m concerned with is that the theory should predict the results of measurements,’ said Stephen Hawking in 1994. And dipping back a little further in time, we ﬁnd the 19th-century polymath John Herschel expressing the same thought: ‘To experience we refer, as the only ground of all physical enquiry.’ These are not just personal opinions or propaganda; the principle that only empirical evidence carries weight in scientific argument is widely enforced across the scientific disciplines by scholarly journals, the principal organs of scientific communication. Indeed, it is widely agreed, both in thought and in practice, that science’s exclusive focus on empirical evidence is its greatest strength.
et there is more than a whiff of dogmatism about this exclusivity. Feynman, Hawking, Herschel all insist on it: ‘the sole judge’; ‘all I’m concerned with’; ‘the only ground’. Are they, perhaps, protesting too much? What about other considerations widely considered relevant to assessing scientific hypotheses: theoretical elegance, unity, or even philosophical coherence? Except insofar as such qualities make themselves useful in the prediction and explanation of observable phenomena, they are ruled out of scientiﬁc debate, declared unpublishable. It is that unpublishability, that censorship, that makes scientific argument unreasonably narrow. It is what constitutes the irrationality of modern science – and yet also what accounts for its unprecedented success. more>

Unlocking value: Four lessons in cloud sourcing and consumption
Companies that are successful in sourcing and managing the consumption of cloud adopt a more dynamic, analytical, and demand-driven mindset.
By Abhi Bhatnagar, Will Forrest, Naufal Khan, and Abdallah Salami – Cloud adoption is no longer a question of “if” but of “how fast” and “to what extent.” Between 2015 and 2020, the revenue of the big-three public cloud providers (AWS, Microsoft Azure, and Google Cloud Platform) has quintupled, and they have more than tripled their capital-expenditures investment to meet increasing demand. And enterprises are ever more open to cloud platforms: more than 90 percent of enterprises reported using cloud technology in some way.
These trends reflect a world where enterprises increasingly “consume” infrastructure rather than own it. The benefits of this model are plentiful. Cloud adopters are attracted by the promise of flexible infrastructure capacity, rapid capacity deployment, and faster time to market for digital products. The COVID-19 crisis has accentuated the need for speed and agility, making these benefits even more important. From an infrastructure-economics perspective, perhaps the most attractive innovation of cloud is the ability to tailor the consumption of infrastructure to the needs of the organization. This promises greater economic flexibility by transforming underutilized capital expenditures into optimally allocated operations expenditures.
While this concept is attractive in theory, many enterprises are facing challenges in capturing the value in reality. Enterprises estimate that around 30 percent of their cloud spend is wasted. Furthermore, around 80 percent of enterprises consider managing cloud spend a challenge. Thus, even though more than 70 percent of enterprises cite optimizing cloud spend as a major goal, realizing value remains elusive.
In our experience, a major driver of value capture is transforming the approach to sourcing and consuming cloud. Enterprises that approach this task with a traditional sourcing and infrastructure-consumption mindset are likely to be surprised by the bill. The flexibility to consume cloud as needed and cost effectively places responsibility on enterprises to maintain a real-time view of their needs and continuously make deliberate decisions on how best to adjust consumption. more>

What are the current challenges and opportunities for today’s submarine networks? What’s next? Find out what will be covered in our upcoming webinar with TeleGeography.
Current state of the global submarine network
By Brian Lavallée – Internet traffic patterns have shifted, and volumes have surged, as the telecom industry addresses the “new normal” where people are increasingly working, learning, and playing from home. Although the global network infrastructure has bent in certain parts of the network, it hasn’t broken. This is a testament to how reliability and availability is in the DNA of our industry and is more important than ever before.
According to TeleGeography, global Internet bandwidth rose last year by 35%, which was a major increase over the previous year’s 26% growth. This increase was driven largely in response to the global pandemic and represents the largest single-year increase since 2013. It also raised the most recent four-year CAGR to 29%. Being able to connect with each other, and to machines, has consistently increased in importance, but in 2020, this took on a whole new level of importance related to our social and economic well-being.
The pace of technology innovation in the telecom industry has accelerated over the past decade in response to growing demands related to our increasing affinity for always-on broadband connectivity. Even the once closed and proprietary world of submarine networks has evolved with the advent of Open Cables, programmable coherent modems, ROADMs, active branching units, C+L band, and more recently, open APIs, intelligent data-driven automation, and analytics. Together, these amazing technologies address challenges related to network scalability, availability, and flexibility during “normal” times. They’re even more important today as we’re mandated to increasingly work and play remotely. more>
