Everything you can do I can do better!

Filed under: Uncategorized — Azer Bestavros @ 9:30 am

Essence of the Q&A on a panel that I participated in at Hanscom Air Force Base on Cloud Security:

Google: We take cloud security very seriously. Your information is secure in our cloud. Trust us. 

Me: What if I don’t trust you? 

Google: How dare you not trust us? If you don’t trust us, who do you trust?

Me: Proofs. Got any?

Google: Anything you can do I can do better; I can do anything better than you.

Me: That’s not a proof; that’s a song. I can’t trust that!

Go figure!

Pioneering a “Cloud Mall” for Innovation and Disruption

It is truly rewarding to see an idea — that many have belittled as impractical, unrealistic, and only of academic interest — finally take on a life of its own, culminating almost seven years of work on the CloudCommons project!

With Massachusetts pledging $3 million in state support, it was wonderful for me to represent the entire BU and MGHPCC team in the proverbial handshake with the Governor of Massachusetts who announced the launch of the Massachusetts Open Cloud (MOC) — a path-breaking computing cloud that could spur economic growth and technology innovation.

Quoting the story as reported by Bostonia:

The plan calls for hosting the MOC at the MGHPCC data center, where it would tap the computational power of BU and its MOC partners, who have jointly contributed $16 million to MGHPCC, leveraging the $3 million matching grant from the state. Besides the participating universities, MOC partners are tech firms Red Hat, Cisco, EMC, Juniper Networks, SGI, Mellanox, Plexxi, Riverbed, Enterprise DB, Cambridge Computer Services, and DataDirect Networks.

The MOC concept of a cloud marketplace grew out of BU research in 2009. In a recent paper, Bestavros and Krieger argue that closed clouds usually have a single provider, who “alone has access to the operational data.” For this and other reasons, they write, “in the long run, if only a handful of major providers continue to dominate the public cloud marketplace, then any innovation can only be realized through one of them.”

With a cloud designed like the MOC, their paper says, “many stakeholders, rather than just a single provider, participate in implementing and operating the cloud. This creates a multisided marketplace in which participants freely cooperate and compete with each other, and customers can choose among numerous competing services and solutions.”

Another advantage: an open cloud would be more secure than a closed one, Bestavros and Krieger say. It is “the best way to make sure that software is clean,” according to Bestavros, especially as American tech companies complain that federal computer snooping might scare off billions of dollars’ worth of cloud computing customers. With a public, open cloud like the MOC, “the National Security Agency cannot put backdoors in an open-source code, because you can see what the software is doing,” he says.

On Social Engineering

Filed under: Uncategorized — Azer Bestavros @ 10:04 am

I never thought that the Boston Globe will quote me on “Social Engineering” — but that’s what they decided to pick out of a long interview for their article “Around Internet, password fatigue setting in Protection becomes a not-so-secret frustration”…

E-mail access in particular is a gateway to other sites because it contains so much personal information, and hackers can exploit a that weak link to work their way into a more lucrative target, such as a bank account, said Azer Bestavros, a professor of computer science at Boston University.

“It’s called ‘social engineering,’ ” he said. “You could be part of a bigger plot. They use you as a step in a bigger scheme. This is why a person who would appear to be totally average could be useful to a hacker.”

On Educating Lawmakers and the Public

Filed under: Uncategorized — Azer Bestavros @ 9:52 am

My little contribution to reaching out and “educating” policy makers and the public about the opportunities and challenges of cloud computing, and more importantly, the role that academia plays as an impartial watchdog.

Institute Director, Azer Bestavros, was appointed as board member of the Cloud Computing Caucus Advisory Group. The Cloud Computing Caucus Advisory Group is a non-profit, non-partisan coalition of technology companies and industry groups focused on educating lawmakers and the public about cloud computing as well as other information technology issues. Members of the Board represent some of the largest cloud providers and stakeholders, including Microsoft, Google, Amazon, IBM, EMC, among others.

Thank You Paul!

Portait of Paul Maritz

A $300,000 gift by Paul Maritz, Chief Executive Officer of Pivotal (an EMC-backed startup), is providing the critical resources needed to launch BU’s Cloud Computing Initiative (CCI), which is incubated at the Hariri Institute for Computing. In a recent visit to the Institute, Paul met with key faculty members involved in CS and CCI projects focusing on novel cloud platforms for high-performance computing, big data, and cyber security. The discussions that ensued helped distill three thrusts required to create “An Advanced Platform for Data Science” at Boston University, which he is generously funding by this gift. Paul’s support is quite important, not only for its financial implications, but also because the imprimatur of his name will open doors and convey recognition of CCI and Institute projects.

Supercomputing “for the rest of us!”

Filed under: Uncategorized — Azer Bestavros @ 10:15 am

On July 10, 2013, The Council on Competitiveness, in conjunction with the U.S. House of Representatives Science and National Labs Caucus, held a briefing titled Extreme Computing: Why United States Industry, National Labs, and Academia Need Advanced Computing.

Bestavros speaks at congressional briefing

As one of four speakers, I was invited to participate in this briefing, representing Boston University and academe in general. In my prepared remarks and in follow-up discussions with congressional staff I shared insights on the Massachusetts Green High Performance Center (MGHPCC) and the opportunities that “HPC in the cloud” could offer to society and the importance of securing and hardening our cloud computing infrastructure. The basic tenet of my remarks were that it is about time that HPC and super-computing in general be accessible “to the rest of us” — as opposed to remaining hostage to the scientific computing community of the last century! Speaking of which, is there really a field of science that is not computational? It’s about time we break the mold and make HPC accessible to the myriads of HPC applications that are not being served because they are not serving the “gatekeepers” of scientific computing.

In a thank you note to Boston University, The Council noted that members of the congressional staff and guests were“thrilled to learn of this historic collaboration among the five MGHPCC universities, state government and private industry and its partnership with K-12 public schools and community colleges on new educational and workforce development initiatives.”

Social Science Face-lift

Filed under: Uncategorized — Azer Bestavros @ 10:22 pm

A blog post in the New York Times argues that the advent of new research methodologies and the pursuit of new opportunities for exciting interdisciplinary collaboration suggest that social science disciplines are due for an overhaul that resembles the face-lift of many natural science disciplines, which were transformed at least in part by computing.   It’s about time!

CS competencies and K12 education: Q&A

Filed under: Uncategorized — Azer Bestavros @ 10:40 am

Massachusetts lawmakers are debating a proposal that would mandate computer science classes in all Massachusetts public schools. The plan would integrate computer skills into the state’s public school curriculum and standardized tests starting as early as the eighth grade. As part of the coverage of this story, I was asked by a local online news outlet to provide my thoughts and comments…

Imagine That!

Filed under: Uncategorized — Azer Bestavros @ 11:34 pm

A provocative article by Clay Shirky (writer, consultant and teacher on the social and economic effects of Internet technologies) entitled Napster, Udacity, and the Academy makes parallels between the Music Industry and the Higher Education “industry”.

Quoting from the end of the article:

“In the academy, we lecture other people every day about learning from history. Now its our turn, and the risk is that we’ll be the last to know that the world has changed, because we can’t imagine—really cannot imagine—that story we tell ourselves about ourselves could start to fail. Even when it’s true. Especially when it’s true.”

Imagine that!

How quickly things change!

Filed under: Uncategorized — Azer Bestavros @ 4:44 pm

Five or so years ago, I served on a provost committee headed by Jim Collins to look into building a library in front of the College of Communication. At the time, I was one of three dissenting voices about the need for (more) book shelves and robotic-operated stacks, instead calling for nice seating, espresso machines, magazine racks, and large wall LCD displays for visualizations, telepresence, etc. — only to be ridiculed by the library people, including the one quoted in this BU Today article as saying:

During the decades when Mugar acquired books only, Hudson says, “what we had been doing is building more book stacks and taking away seating.” Digitization reversed that, allowing “us to take some of the stacks down and start rebuilding student use space—computers, but also carrels, group interactive spaces, classrooms.” In short, “we’re more than books” and need student work space.

How quickly things change!
