The Week in Internet News: A Change in U.S. Internet Policy?

Winds of change: U.S. President-elect Joe Biden will significantly change U.S. government policy focused on the Internet, Vox.com says. A Biden administration is likely to bring back net neutrality rules and push for policies that widen Internet access and make it more affordable. The Biden team may also provide more subsidies to lower-income people and open up more radio frequency bands for high-speed 5G networks.

Accessing growth: The growth of Indonesia’s digital economy depends on equal access to the Internet, but 12,000 villages across the country still lack access, Kompas.com reports. Indonesia’s Finance Minister Sri Mulyani Indrawati is pushing for digital infrastructure to be distributed throughout the country. The government has a 2021 budget of 30 trillion rupiahs ($2.1 billion USD) to develop information and communication technology infrastructure.

Lowering the Zoom: Video-conferencing service Zoom has settled a U.S. Federal Trade Commission complaint saying that it overstated its encryption protections for several years, TechCrunch says. “Zoom’s misleading claims gave users a false sense of security … especially for those who used the company’s platform to discuss sensitive topics such as health and financial information,” the agency said. Zoom has agreed to start a vulnerability management Continue reading

Achieving 100Gbps intrusion prevention on a single server

Achieving 100 Gbps intrusion prevention on a single server, Zhao et al., OSDI’20

Papers-we-love is hosting a mini-event this Wednesday (18th) where I’ll be leading a panel discussion including one of the authors of today’s paper choice: Justine Sherry. Please do join us if you can.

We always want more! This stems from a combination of Jevon’s paradox and the interconnectedness of systems – doing more in one area often leads to a need for more elsewhere too. At the end of the day, there are three basic ways we can increase capacity:

  1. Increasing the number of units in a system (subject to Amdahl’s law).
  2. Improving the efficiency with which we can coordinate work across a collection of units (see the Universal Scalability Law)
  3. Increasing the amount of work we can do on a single unit

Options 1 and 2 are of course the ‘scale out’ options, whereas option 3 is ‘scale up’. With more nodes and more coordination comes more complexity, both in design and operation. So while scale out has seen the majority of attention in the cloud era, it’s good to remind ourselves periodically just what we really can do on a single Continue reading

New Content: Graph Algorithms – Flows and Connectivity

Last week we enjoyed the second half of Graph Algorithms lecture by Rachel Traylor, this time focusing on flow- and connectivity challenges.

After an easy start defining flows and walking us through various maximum flow algorithms, Rachel explained circulations and saturating flows, switched into high gear with (supposedly painless) intro to linear programming and minimum cost flow problems, and concluded with dynamic flows and using flows to explore graph connectivity.

Network, It’s Time to Modernize!

The network is a critical component of any IT environment. When it works, it’s “normal” and few notice it. But the smallest glitch can have devastating business impacts.  For over a decade, networking has been adapting to become more programmable, closer to applications, and easier to use. At the same, the number of devices increased drastically while and applications exponentially. More than ever, there is a need to adapt the network to the new paradigm of multi-cloud environments, and to make it on-demand, easy to use, and simple. The network should be transparent to applications and users, yet allow the most complex environments to communicate reliably.

Let’s dig into the three pillars of a Modern Network framework.

Modern App Connectivity Services

User experience is paramount in today’s world. Applications and data are increasingly distributed across multiple on-premises data centers and public, private, and multi-cloud environments. At the same time, users and devices (including IoT) are spreading out from a centralized corporate headquarters to branch offices, remote worksites, and, increasingly, home offices. This new reality means that, more and more, machines are talking to machines and applications are talking to applications, creating network complexity that can only be mitigated by Continue reading

Using AI to manage IoT sensor power

Sensor power loss is the scourge of IoT.Deploying millions of sensors is pretty much a useless endeavor if the devices continually run out of power. IoT sensors can't collect or transmit data without power.That's one reason researchers are exploring ambient energy harvesting. Numerous projects have shown that small amounts of power can be generated by converting ambient energy in the environment – from stray magnetic fields, humidity, waste heat, and even unwanted wireless radio noise, for example – into usable electrical energy to power the IoT.To read this article in full, please click here

Used IT equipment: Millennials push enterprises into the circular economy

The Millennial generation is becoming a driving force behind the circular economy of used IT equipment.IT shops have typically bought used gear if they needed to replace old equipment and couldn't get parts from the vendor. But the idea of buying a low-mileage server with one or two years of use wasn't very popular. Companies typically bought new.But that's changing. IT shops of all sizes are increasingly buying used gear, both brand name and white box brands from China, according to IDC. The research firm puts the CAGR at 5% and estimates sales of used IT infrastructure gear will reach $36 billion by 2024. The deals are being done through the major OEMs as well as resellers like ITRenew, which buys servers from hyperscalers, refreshes them, certifies they are functioning, and resells them.To read this article in full, please click here

Why You Should Cancel Your Social Media Accounts

Over the past ten years, the world generally has noticed serious social media websites like MySpace, Twitter, and Facebook which have all generated different ways for people to interact and connect with other people. Facebook is known as the biggest social website. Today we have more than a billion users that make use of Facebook. In the future, with kids growing up and joining the social media platform, the number of people will increase. Facebook has been used for both personal and business communication, and its usage has brought lots of advantages in terms of sharing ideas, increasing connectivity, and learning online.

But as time passes, some studies have merged networking online with different disorders that come from the minds of the users. These disorders include low self-esteem, anxiety, depression, and a lot of others. Because social media is a product of the 21st century, lots of questions relating to their impact on the health of its users mentally haven’t gotten desired answers yet. Because these online services are linked to the general population, any confirmed connection in the future between these diseases and these social media platforms could turn to a serious problem.

Achieve Multi-Cloud Application Scalability for Modern Apps

The modern application is dynamic and highly adaptive to changes in demand. It lives across multiple clusters and clouds. And it is highly distributed with hundreds of microservices servicing the requirements of rapid feature releases, high resiliency, and on demand scalability. In such a world, we simply cannot afford to continue to rely solely on the network architectures of the last decade.

Modern applications need a Modern Network—one that simplifies operations, reduces IT overhead and prioritizes user needssuch that organizations can empower users with fast, reliable and secure application access wherever and whenever they do business, regardless of the underlying infrastructure or connectivity. This requires adopting the public cloudor even multiple public cloudsas an extension of on-premises infrastructure. What enterprises need is a common, multi-dimensional framework that provides availability, resiliency, and security for modern applications, with the ability to abstract connectivity, identity, and policy via declarative intents. These dimensions of control are paramount for modern applications improving the visibility and control of assets that are ephemeral in nature and not directly under the Continue reading
