IDG Contributor Network: Bandwidth alone won’t solve application performance problems

When applications were exclusively hosted in the corporate data center, remote sites had much lower bandwidth and each required its own WAN optimization device. According to conventional wisdom, if we increase bandwidth, performance will improve. However, without decreasing latency, application performance will continue to suffer—no matter how much bandwidth we throw at the network.Four main things contribute to latency: Propagation delay Serialization delay Queuing delay Processing delay Propagation delayThis is the delay between two endpoints. For example, propagation delay is based on the speed of light measured at 5ms per 1000Km. The one-way propagation delay between a data center in New York and a branch in San Jose would be at least 24ms. This assumes a direct fiber path and no router hops, in which case the propagation delay will be significantly higher. For large carriers, one-way delays average 35-45 msec.To read this article in full or to leave a comment, please click here

Worth Reading: Solving network documentation with code

A major issue with network documentation is how to properly explain the policies required to enable a service on the network. In the above diagram, I have a basic application traffic flow overlaid on the network infrastructure the traffic must traverse. Six network device types participate in the handling of traffic for this application all requiring some form of policy definition on them. A change in policy may require a change in any number of network devices to support that change. —route-spf

Vonage’s cloudy strategy is now clear

Alan Masarek has been CEO of Vonage since November 2014. Since then, the company has undergone a transformation, building on its roots as a home phone replacement company to become a leading provider of cloud communications for business. Vonage jump-started its leadership position as a business communications provider through acquisitions and has been very active acquiring companies to complement the core consumer VoIP offering and early SMB offering the company had when Masarek assumed the role. Masarek’s vision is for Vonage to be the global leader in cloud communications by transforming the way people connect and businesses operate through integrated and contextual communications whenever and however people choose to communicate.To read this article in full or to leave a comment, please click here

Cyberespionage group Patchwork sets its sights on multiple industries

A cyberespionage group known for targeting diplomatic and government institutions has branched out into many other industries, including aviation, broadcasting, and finance, researchers warn.Known as Patchwork, or Dropping Elephant, the group stands out not only through its use of simple scripts and ready-made attack tools, but also through its interest in Chinese foreign relations.The group's activities were documented earlier this month by researchers from Kaspersky Lab, who noted in their analysis that China's foreign relations efforts appear to represent the main interest of the attackers.To read this article in full or to leave a comment, please click here

Hackers can pick off, inject wireless keyboard keystrokes from 8 vendors, maybe more

A vulnerability across at least eight brands of wireless keyboards lets hackers read keystrokes from 250 feet away, according to wireless security vendor Bastille.The problem is that the keyboards transmit to their associated PCs without encryption, and it’s just a matter of reverse engineering the signals to figure out how to read what keys are being hit, say Bastille researchers. An attacker could inject keystrokes while the keyboard is idle and the machine is logged in, they say, using a dongle that can be fashioned for less than $100.To read this article in full or to leave a comment, please click here

This new Outlook feature will organize your inbox for you

Microsoft is finally bringing one of the best features of its Outlook mobile app to the desktop. Users of Outlook on Mac and Windows will start seeing their inbox separated out into two tabs: Focused and Other.As the name implies, the Focused Inbox is supposed to hold all of a user's important emails, while Other contains everything else. Users can train the system by moving email to and from the Focused Inbox, and establishing rules about certain senders and subjects.When new messages come into the Other inbox, a banner will show up at the top of the list of focused messages letting users see how many new messages are in that section of their inbox, along with a select list of senders.To read this article in full or to leave a comment, please click here

Verizon must pay even if Mozilla walks from Yahoo search deal

Verizon, which today announced its intention to purchase Yahoo for $4.8 billion, will be on the hook to Mozilla for over $1 billion through 2019.According to Yahoo's CEO, Marissa Mayer, Verizon may be liable for partial payments even if Mozilla cuts ties to Yahoo and seeks another search provider.Earlier this month, Recode and the New York Times claimed that the 2014 Yahoo-Mozilla contact gave Mozilla the right to switch to another search provider if Yahoo was sold.To read this article in full or to leave a comment, please click here

5 innovative ways to solve unimportant problems

5 innovative ways to solve unimportant problemsImage by Envoy/Pacific ContentAll work and no play not only makes Jack a dull boy, it makes for a pretty disengaged workplace. In Silicon Valley, especially, the competition for talent is cutthroat, and offering fun and innovative projects is a great way to attract and retain elite talent. Digital guest management and visitor sign-in solutions company Envoy's CEO Larry Gadea and his team wanted a way to publicly recognize the efforts of employees. Technology provided the answer: an automated 'sales gong' that would reverberate throughout the office whenever a new subscriber signs up. The solution's built using a Raspberry Pi connected to a series of relays, and the mechanism to ring the gong is written into the main codebase. Any time there's a new subscriber, the system springs into action and rings the gong. The overall effect is more than just to recognize the efforts of salespeople, marketers and developers within the company, Gadea says. It's to remind Envoy's teams of the "bigger picture" and to build on the culture of innovation and teamwork at the company. "We wanted to remind everyone that all the hard work we're doing is making an Continue reading

Health care organizations 114 times more likely to be ransomware victims than financial firms

Health care organizations were 114 times more likely to hit by ransomware infections than financial firms, and 21 times more likely than educational institutions, according to a new research report by Solutionary.The Omaha-based security firm detects millions of attacks a year, according to threat intelligence analyst Terrance DeJesus. But while health care accounts for just 7.4 percent of the company's client base, it saw 88 percent of all ransomware attacks during the first half of this year."These numbers do not count all of the email delivery or exploit kit activity that happens pre-infection and would be attempts to deliver ransomware," he said. "These are confirmed ransomware outbreaks on directly affected systems."To read this article in full or to leave a comment, please click here

IDG Contributor Network: Twilio API sinks all the application sync issues

It is only a few short weeks since Twilio, the communications platform developer, had its stock market debut. It's also a safe bet that in these turbulent times for tech stocks, Twilio spent much time thinking about product and other announcements it could make post-listing to keep the markets positive about its performance.And so it is doing so today with a seemingly small, but actually pretty cool piece of news for the company. Twilio is rolling out Sync, a tool designed to help keep applications in sync across different devices and sessions. The idea being that developers can build experiences that are consistent across the different devices they wish to support. It also means they can add multi-user collaboration capabilities into their applications without having to think about the pesky details of state.To read this article in full or to leave a comment, please click here
