IDG Contributor Network: How to test SD-WANs

Whenever I speak with companies starting to research SD-WANs, the question about testing invariably comes up. Like probably any enterprise device, SD-WANs are filled with features. And as with any major WAN acquisition, testing those features prior to purchase is incredibly important. SD-WAN vendors have their own nuances and strengths. You need to be sure those strengths align with your environment.RELATED: SD-WAN: What it is and why you will use it one day As an edge device, there’s very little in terms of packet processing that needs to be tested in an SD-WAN node. But that doesn’t mean SD-WAN node testing isn’t important. Here are some tips for what you can look for when running your proof of concept (POC) from my buddy DC Palter, CEO at network testing simulator company Apposite Technologies, and our experiences here at SD-WAN Experts.To read this article in full or to leave a comment, please click here

How to speed up your MySQL with replication to in-memory database

Original article available at https://habrahabr.ru/company/mailru/blog/323870/

I’d like to share with you an article based on my talk at Tarantool Meetup(the video is in Russian, though). It’s a short story of why Mamba, one of the biggest dating websites in the world and the largest one in Russia, started using Tarantool. Why did we decide to busy ourselves with MySQL-to-Tarantool replication?

First, we had to migrate to MySQL 5.7 at some point, but this version didn’t have HandlerSocket that was being actively used on our MySQL 5.6 servers. We even contacted the Percona team — and they confirmed MySQL 5.6 is the last version to have HandlerSocket.

Second, we gave Tarantool a try and were pleased with its performance. We compared it against Memcached as a key-value store and saw the speed double from 0.6 ms to 0.3 ms on the same hardware. In relative terms, Tarantool’s twice as fast as Memcached. In absolute terms, it’s not that cool, but still impressive.

Third, we wanted to keep the whole existing architecture. There’s a MySQL master server and its slaves — we didn’t want to change anything in this structure. Can MySQL 5.6 slaves with HandlerSocket be replaced Continue reading

  • Analyst Webinar: Forrester Study on Hybrid Memory NoSQL Architecture for Mission-Critical, Real-Time Systems of Engagement. Thursday, March 30, 2017 | 11 AM PT / 2 PM ET. In today’s digital economy, enterprises struggle to cost-effectively deploy customer-facing, edge-based applications with predictable performance, high uptime and reliability. A new, hybrid memory architecture (HMA) has emerged to address this challenge, providing real-time transactional analytics for applications that require speed, scale and a low total cost of ownership (TCO). Forrester recently surveyed IT decision makers to learn about the challenges they face in managing Systems of Engagement (SoE) with traditional database architectures and their adoption of an HMA. Join us as our guest speaker, Forrester Principal Analyst Noel Yuhanna, and Aerospike’s VP Marketing, Cuneyt Buyukbezci, discuss the survey results and implications for your business.

Intel Vigorously Defends Chip Innovation Progress

With absolute dominance in datacenter and desktop compute, considerable sway in datacenter storage, a growing presence in networking, and profit margins that are the envy of the manufacturing and tech sectors alike, it is not a surprise that companies are gunning for Intel. They all talk about how Moore’s Law is dead and how that removes a significant advantage for the world’s largest – and most profitable – chip maker.

After years of this, the top brass in Intel’s Technology and Manufacturing Group as well as its former chief financial officer, who is now in charge of its manufacturing, operations, …

IBM on the state of network security: Abysmal

The state of online security is darn dreadful. At least if you look at the results from the IBM Security’s 2017 IBM X-Force Threat Intelligence Index released today which contains myriad depressing nuggets such as: The number of records compromised grew a historic 566% in 2016 from 600 million to more than 4 billion -- more than the combined total from the two previous years. In one case, a single source leaked more than 1.5 billion records [see Yahoo breach]. In the first three months of 2016, the FBI estimated cybercriminals were paid a reported $209 million via ransomware. This would put criminals on pace to make nearly $1 billion from their use of the malware just last year. In 2016, many significant breaches related to unstructured data such as email archives, business documents, intellectual property and source code were also compromised. The most popular types of malcode we observed in 2016 were Android malware, banking Trojans, ransomware offerings and DDoS-as-a-service vendors. Since DDoS tools are mostly sold as a service and not as malware per se, we will focus here on banking Trojans, Android malware and ransomware. In December 2016, a malware developer with an ongoing banking Trojan Continue reading

Amazon’s successful drone delivery test doesn’t really prove anything

Last week, Amazon Prime Air released dramatic video of a drone delivering bottles of sunscreen in a test at Amazon's MARS conference in a controlled environment at Palm Springs International Airport in California.Pretty cool stuff, even if the company has already demonstrated the ability to complete actual commercial drone deliveries in the United Kingdom. But my longstanding skepticism for the practicality of drone deliveries hasn’t diminished. More than two years ago, for example, I listed 10 reasons Amazon's drone delivery plan still won't fly.To read this article in full or to leave a comment, please click here

Worth Reading: Pervasive, Dynamic Authentication Of Things

Authentication of physical items is an age-old problem. Common approaches include the use of bar codes, QR codes, holograms, and RFID tags. Traditional RFID tags and bar codes use a public identifier as a means of authenticating. A public identifier, however, is static: it is the same each time when queried and can be easily copied by an adversary. Holograms can also be viewed as public identifiers: a knowledgable verifier knows all the attributes to inspect visually. It is difficult to make hologram-based authentication pervasive; a casual verifier does not know all the attributes to look for. Further, to achieve pervasive authentication, it is useful for the authentication modality to be easy to integrate with modern electronic devices (for example, mobile smartphones) and to be easy for non-experts to use. —ACM

Invisibility, teleportation among top superpowers that IT pros want

Updating Apple iOS will protect you from this fake ransomware attack

Lookout researchers warned of a campaign involving fake ransomware attacks that attempt to extort money from users of mobile Safari. Victims are accused of accessing illegal pornography and the browser appears to be locked up unless a “ransom” is paid.“Your device has been locked for illegal pornography,” the message stated on a site with security agency icons such as NSA and Interpol at the bottom of the page. An overlay pop-up warned that Safari “cannot open page” with “OK” underneath the message. However, the dialog would not go away no matter how many times the victim tapped “OK.”Lookout said, “Each time he tapped ‘OK’ he would be prompted to tap ‘OK’ again, effectively putting the browser into an infinite loop of dialog prompts that prevented him from using the browser.”To read this article in full or to leave a comment, please click here

How Microsoft plans to address AI and machine learning challenges

Microsoft, Google and IBM face difficult challenges in winning early enterprise adopters of artificial intelligence (AI) and machine learning (ML). Microsoft AI Research Vice President Peter Lee shed some like on how Microsoft will meet those challenges when we met at this week’s MIT Technology Review EmTech Digital conference.Lee began with the same explanation that he gave to Microsoft CEO Satya Nadella. Nadella, a former research engineer, does not need to have technology spoon fed to him, but he does need to understand the framework used to manage the future of the vertical industries transferred to the stewardship of Microsoft’s AI group. It is a big bet, amounting to 6,000 employees or one-fourth of the company and includes leading industry businesses such as healthcare, education, automotive, finance and retail. A very big bet on the future of AI, indeed.To read this article in full or to leave a comment, please click here

Privacy advocates plan to fight Congress’ repeal of ISP privacy rules

Privacy advocates haven't given up the fight after the U.S. Congress voted to allow ISPs to sell customers' browsing histories and other personal information without their permission.On Tuesday, the House of Representatives voted 215 to 205 to strike down ISP privacy regulations approved by the Federal Communications Commission only months ago. House's passage of a resolution of disapproval followed a Senate vote to pass the same resolution days earlier. President Donald Trump is expected to sign the Republican-pushed bill. But Senator Ed Markey, a Massachusetts Democrat, said he will introduce new legislation to require the FCC to pass new ISP privacy rules.To read this article in full or to leave a comment, please click here
