Don’t Throw the Multicloud Out with the Bathwater

https://twitter.com/CTOAdvisor/status/1103034794781429761 https://www.youtube.com/watch?v=wNOA-sPqf80& https://twitter.com/randybias/status/1103713819195408384 https://twitter.com/C_Z_Raisch/status/1103723011037900800 Keith was totally right to push back on the idea that multicloud was about cost optimization. Not only is this a fantasy, it’s also off-brand for most enterprises. In my experience, the enterprise is totally fine paying a premium on what they consider best of breed technology solutions. to me, multicloud isn’t about trying to boil the ocean and build some master plan for world dominance that includes dynamic blah blah blah.

Deutsche Welle Profiles Community Networks Around the World

How can the Internet change lives in rural and remote regions? Deutsche Welle, Germany’s public broadcaster, asks these questions in three stories that explore community networks in Zimbabwe, the Republic of Georgia, and South Africa.

Read about the community networks and listen to their stories!

Murambinda Works started as an Internet café in 2002 in the Buhera District in eastern Zimbabwe. Since then it’s grown to provide training in computer literacy for teachers at nearly 218 primary and secondary schools. Murambinda Works, in partnership with the Internet Society and others, is also working to connect eight schools, one nurse training school, and offices of the Ministry of Education.

Tusheti, a mountainous, isolated region in the Republic of Georgia, had been left unconnected by commercial operators. The Internet Society partnered with its Georgian Chapter and other local organizations to help build access to the Internet, which was completed in 2017. (The Tusheti community network was also profiled in The New York Times.)

The Zenzeleni Network in Mankosi, is one of South Africa’s most economically disadvantaged communities. Zenzeleni – which means “do it yourself” in the local language, isiXhosa – was launched in 2012 to provide affordable voice service Continue reading

Cisco uncorks 26 security patches for switches, firewalls

Cisco has bundled 25 security advisories that describe 26 vulnerabilities in Cisco NX-OS switch and Firepower FXOS firewall software.While the 26 alerts describe vulnerabilities that have a Security Impact Rating of “High,” most –23 – affect Cisco NX-OS software, and the remaining three involve both software packages.[ Also see What to consider when deploying a next generation firewall. | Get regularly scheduled insights by signing up for Network World newsletters. ] The vulnerabilities span a number of problems that would let an attacker gain unauthorized access, gain elevated privileges, execute arbitrary commands, escape the restricted shell, bypass the system image verification checks or cause denial of service (DoS) conditions, Cisco said.To read this article in full, please click here

2019 Database Trends – SQL vs. NoSQL, Top Databases, Single vs. Multiple Database Use

Most Important Metric Tracked For Database Performance - Queries, Reliability & Memory

Wondering which databases are trending in 2019? We asked hundreds of developers, engineers, software architects, dev teams, and IT leaders at DeveloperWeek to discover the current NoSQL vs. SQL usage, most popular databases, important metrics to track, and their most time-consuming database management tasks. Get the latest insights on MySQL, MongoDB, PostgreSQL, Redis, and many others to see which database management systems are most favored this year.

Episode 46 – Bridging The Gap Between IT And The Business

Historically, engineers and practitioners have had a hard time communicating IT’s value to business leadership. This gap between IT and the business will present even greater challenges as businesses grow to depend on their networks and systems for even more strategic advantage. In this episode we explore some of the reasons why this gap exists and discuss some potential things you can do to help bridge the gap between IT engineering and business leadership.

Loggly

Loggly is a cloud logging and and analysis platform. This article will demonstrate how to integrate network events generated from industry standard sFlow instrumentation build into network switches.
Loggly offers a free 14 day evaluation, so you can try this example at no cost.
ICMP unreachable describes how monitoring ICMP destination unreachable messages can help identify misconfigured hosts and scanning behavior. The article uses the sFlow-RT real-time analytics software to process the raw sFlow and report on unreachable messages.

The following script, loggly.js, modifies the sFlow-RT script from the article to send events to the Loggly HTTP/S Event Endpoint: 
var token = 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx';
  
var url = 'https://logs-01.loggly.com/inputs/'+token+'/tag/http/';

var keys = [
  'icmpunreachablenet',
  'icmpunreachablehost',
  'icmpunreachableprotocol',
  'icmpunreachableport'
];

for (var i = 0; i < keys.length; i++) {
  var key = keys[i];
  setFlow(key, {
    keys:'macsource,ipsource,macdestination,ipdestination,' + key,
    value:'frames',
    log:true,
    flowStart:true
  });
}

setFlowHandler(function(rec) {
  var keys = rec.flowKeys.split(',');
  var msg = {
    flow_type:rec.name,
    src_mac:keys[0],
    src_ip:keys[1],
    dst_mac:keys[2],
    dst_ip:keys[3],
    unreachable:keys[4]
  };

  try { http(url,'post','application/json',JSON.stringify(msg)); }
  catch(e) { logWarning(e); };
}, keys);
Some notes on the script:
  1. Modify the script to use the correct token for your Loggly account.
  2. Including MAC addresses can help identify Continue reading

Why Wi-Fi needs artificial intelligence

This week Juniper Networks plunked down $405 million to acquire Wi-Fi vendor Mist Systems. As always, Network World's Michael Cooney did a fine job covering the news, so I won’t rehash that. What I want to look at is something specific that Cooney wrote — that “Mist touts itself as having developed an artificial-intelligence-based wireless platform.” Why does Wi-Fi need artificial intelligence (AI)?To read this article in full, please click here
