Microservices Network Architecture 101

A new god is rising in the world of application development – Microservices

The new god promises if not happiness in the next life, scalability, agility and fault tolerance in this life. At the heart of all this, is a simple, age-old axiom that is a key design goal of Unix: do one thing, and do it well. In the evolution of application architectures, single monolithic applications made way for client-server applications, which in turn made the way for microservices. The upending of the old world continues in data centers.

Communication is at the heart of this new religion (one popular theory of the etymology of the word religion is the word “religio” which means “to reconnect”). Every religion and every new technology introduces its own new vocabulary.

Microservices are no different!

In the domain of communications, the new lingo involves things such as MacVlan, IPVlan, Weave, Flannel and Swarm, to just name a few. What are they ? How are they connected ? Is IPVlan a new encapsulation format ? If it’s not a new encapsulation format, what is it ? If it is a new encapsulation format, how is it related to VxLAN ? Why were they invented ? Which one should I use ? What Continue reading

Lawmakers probe large data breaches at US bank insurance agency

Texting while driving messes with your six sense, Texas researchers say

Researchers from the University of Houston and the Texas A&M Transportation Institute (TTI) say drivers are more distracted when they text than when they are being absent minded or are upset while behind the wheel.The researchers, who based their findings on a study of 59 volunteers/drivers, say a mechanism in the brain automatically corrects for jitter in a driver's arms and hands while steering -- as long as the driver is watching the road. Reading or sending texts while driving takes the driver's eyes off the road, and that's where things becomes unsafe.MORE: Cellphone use involved in more than 1 in 4 crashes | 25 real-life ways people have been hurt using their phonesTo read this article in full or to leave a comment, please click here

Nest gives Thread IoT protocol group a new president and a new open-source implementation

Thread, an open wireless protocol for the Internet of things, is getting a boost from one of its biggest boosters, Google-owned Nest Labs. An IPv6 networking protocol built on the 802.15.4 mesh networking standard, Thread is designed to connect hundreds of low-power devices to one other and to the cloud. While the protocol is open, anyone wanting to build Thread-compatible devices had to roll their own software stack implementing it -- until now. Late Wednesday, Nest published the source code for its implementation of the Thread protocol, OpenThread, on Github under a three-clause BSD license, allowing anyone to reuse, modify or redistribute it in source or binary form.To read this article in full or to leave a comment, please click here

8 awesome (and sometimes free) conference call services

Conference calls are a big part of work life today — sometimes too big. Because we spend so much time in meetings, we want conference-calling systems that that launch quickly and work flawlessly so we can get the information we need and move on to other pressing matters. The capability to browse a post-meeting transcript or zoom through an audio recording would be big bonuses, especially for fastidious note-takers who don't always catch everything in real time.The good news is that the leading conference call services are full of features that take the sting out of group calls and online meetings. Standard features typically include audio recording capability, support for screen-sharing, automated transcripts (created by converting digital recordings into text), Web interfaces with hosting tools for managing calls and keeping track of participants, and 24/7 availability. Some services also offer personalized greetings to participants who dial in, customized hold music, operator assistance and a participant “dial-out” feature, where the service calls participants to bring them into the meeting (also referred to as "call me" functionality).To read this article in full or to leave a comment, please click here

Researchers reveal flaws in 7-Zip, users and security vendors affected

Cisco’s Talos researchers discovered two vulnerabilities in 7-Zip, the popular open-source file archiver known for having a high compression ratio and option to password protect compressed files.Even if users hurry to download the newest 16.0 version of 7-Zip, in which the vulnerabilities are reportedly fixed, that doesn’t take care of many products that have used the old 7-Zip libraries and are still vulnerable. Unless vendors do some work, they are vulnerable and users of their products are as well.To read this article in full or to leave a comment, please click here
