Collection of useful, relevant or just fun places on the Internets for 14th June 2013 and a bit commentary about what I’ve found interesting about them:
Amazon Web Services Blog: Amazon Route 53 Adds ELB Integration for DNS Failover – Amazon now has a Global Service Load Balancing capability which does most of what an F5 GTM / Stingray can do and for less CapEx. Will consider for my next project.
Network Congestion and Web Browsing – Insouciant – Interesting discussion on Network Congestion …. except they ignore the actual physical network itself and that’s a bit silly.
Recently, there was discussion on the ietf-http-wg mailing list about the current HTTP/2.0 draft’s inclusion of a SPDY feature that allows the server to send its TCP congestion window (often abbreviated as cwnd) to the client, so it can echo it back to the server when opening a new connection. It’s a pretty interesting conversation so I figured I’d share the backstory of how we got to where we are today.
VMware vCenter Log Insight: Log Management & Analytics – Don’t have any pricing data yet but this is a possible replacement for Splunk for log management and mining.
VMware vCenter™ Log Insight™ delivers automated log management through log analytics, aggregation and search, extending VMware’s leadership in analytics to log data. With an integrated cloud operations management approach, it provides the operational intelligence and enterprise-wide visibility needed to proactively enable service levels and operational efficiency in dynamic hybrid cloud environments.
Mango — What is Mango? – A Web Based markdown editor from the maker of Folding Text. Outstanding feature is text folding (similar to code folding in programming IDE’s
Mango also understands the structure of your Markdown text and can fold and focus based on that structure. Fold headings to get a clear overview of your document, focus on a heading to hide everything else.
Network Janitor | Eventually – My JNCIE-ENT Success! – Kurt Bales passes is JNCIE-ENT and looks forward to returning to normal life. Congratulations Kurt!
I finished up the exam reasonably confident, but I also knew I felt confident after attempt #2. I caught a train home and prepared myself for the 15 business day turn around for the exam results. Luckily I didn’t have to way this long to get my results, and after a couple of days I was advised that I had passed!
I am now JNCIE-ENT #368… and Im very happy / relieved
The Attributes of a Great CLI – I agree, in part. We need a better CLI that has real power and flexibility. I also want a GUI for the basics that I can trust and use without fear (JAVA).
Is this what Cisco has brought to OpenDaylight? Of course, I know there is more but still, an open source Cisco-mimicking CLI is still a rubbish CLI. Perhaps I’ve been spoiled by F5′s Traffic Management SHell (tmsh) which was built from the ground up with modern computing and networking firmly in mind. It was designed in the 21st century (released in 2009), not in the distant past, and boy you can tell the difference. Forgetting Cisco’s direct input, but perhaps not its influence, who thought this was a good idea? Perhaps, as just about every networking vendor’s CLI mimics Cisco’s, no one thought there was a better way, a better design.
Another Big Shiny Switch | In Search of Tech – Matthew Norwood reviews the latest big, hot & heavy switch from HP with lots of pictures and good discussion.
At first glance, one might look at the 12910 or 12916 and think they are Cisco Nexus 7000 clones. Looking at the 12910, you can see the physical resemblance to the Nexus 7010. Upon closer inspection, the platform itself is a bit different. There are actually 10 slots for line cards. The supervisors are located in the rear of the chassis. In actuality, it is a 12 slot chassis. There are also 6 fabric modules instead of 5 on the Nexus 7010. I could go on, but let me just show you the up close pictures and comment on each one. I should also point out that I may be completely wrong in some of my comments. This is a new chassis and other than a spec sheet, not much information is available. I suspect that will change in the near future.
