Unwrapping Tangled Device Configurations – A10 Networks Edition

If you’ve ever tried to interpret an A10 Networks load balancer configuration, or some Cisco Modular QoS CLI commands, you’ll know that doing so involves following references to other parts of the configuration, inevitably ones that appear earlier in the configuration than where you are now, using a display pager which doesn’t support a back command to scroll up a page at a time. In short, it’s a huge pain. The same applies to Cisco ACE and CSM load balancer configurations. The modularity is beautiful and logical, but it’s a massive irritation to reverse engineer.

Spaghetti Configurations

I work regularly with A10 Networks load balancers. ACOS (the A10 OS) has a CLI and configuration format that’s very similar to Cisco IOS. Looking at a particular vPort (A10 terminology for a particular Virtual IP (VIP) and Port combination) and trying to figure out which real servers are related to it is irritating to say the least. Here’s an example of the configuration in the order it appears when you view it:

ip nat pool pool1 10.100.1.1 10.100.1.126 netmask /25
!
health monitor checkstatus
   method http url /status expect code 200

IEEE sets new Ethernet standard that brings 5X the speed without disruptive cable changes

As expected the IEEE has ratified a new Ethernet specification -- IEEE P802.3bz – that defines 2.5GBASE-T and 5GBASE-T, boosting the current top speed of traditional Ethernet five-times without requiring the tearing out of current cabling.The Ethernet Alliance wrote that the IEEE 802.3bz Standard for Ethernet Amendment sets Media Access Control Parameters, Physical Layers and Management Parameters for 2.5G and 5Gbps Operation lets access layer bandwidth evolve incrementally beyond 1Gbps, it will help address emerging needs in a variety of settings and applications, including enterprise, wireless networks.To read this article in full or to leave a comment, please click here

IDG Contributor Network: MarkLogic: Can NoSQL databases support today’s enterprise?

Although I had a few problems with the original PR messages that invited me to meet with MarkLogic, the conversation with Gary Bloom, the company's CEO and president, was well worth the time.Summary of our conversation The following bullets are a quick summary to a complex and engaging conversation: The industry is experiencing several fundimental shifts in both the sources of data and how it is being used. The data is now coming from many types of end user focused devices, applications that combine the efforts of many systems that are housed all over the planet, neither enterprises nor end users will tolerate slow response times or failures, and older approaches that are based upon monolithic application and database design simply can't keep up. While it is true that things have changed in fundimental ways, older applications, systems and designs are not going away. They continue to support enterprise critical applications, but need help dealing with the tsunomi of data coming from everywhere. The state of the art in database architecture has shifted from a "shared nothing" design center to a "shared everything" center that can take advantage of local, virtual and cloud processing and data. Database design Continue reading

5 reasons CEOs should be involved in hiring decisions

Hiring is as much an art as a science. Bring the wrong talent on board, and it'll tank morale and impede performance; hire the right people, and growth will accelerate.However, finding just the right mix of skills, knowledge, experience and personality can feel like a herculean task, says Aytekin Tank, founder and CEO of online form builder JotForm, but for him, it's the most important part of his job.Tank says he involves himself in every hiring decision at JotForm. Google's CEO and cofounder Larry Page famously approves or rejects every one of the company's hires, too. Should your organization follow suit? Here are five reasons why your CEO should be involved in hiring decisions and two reasons they shouldn't.To read this article in full or to leave a comment, please click here

What small business look for when considering SaaS

More and more, small and midsized businesses (SMBs) are turning to cloud-based software to help run their business. Yet many are hesitant to make the move, worrying about safety and cost. So what can Software-as-a-Service (SaaS) providers do to woo SMBs and allay their concerns? Here are eight suggestions on how to make your cloud offering attractive to a smaller business.1. Make sure your software is easy to use – and easy to understand. “Business owners and their employees expect [cloud-based] business apps and services to be as easy to use as their personal consumer apps,” says Ken Oestreich, director, product marketing, Cloud Services, Citrix. “Cloud services and apps need to be intuitive, so people can begin using them without training. The easier your apps and services are to use, the more people will use them, and since service revenues are based on usage, you want customers to use those services frequently and for extended periods of time.”To read this article in full or to leave a comment, please click here

IDG Contributor Network: Sage delivers a payments API. Because APIs are the key to unlocking the future

Until very recently, the accounting software industry was evenly split among the "big three" vendors: Sage broadly owned the U.K. market, Intuit the American, and MYOB the Australasian. Bit players rounded out the other countries not covered by these big three.But in the past few years, several innovative new companies have been founded with the stated aim of disrupting these big vendors. Most notable among them is Xero, but similarly FreshBooks, Kashflow, FreeAgent and others had a crack at the problem space.+ Also on Network World: 10 free tools for API design, development and testing +To read this article in full or to leave a comment, please click here

Wi-Fi connectivity the tip of the technology iceberg for K-12 schools

It’s been about two years since the FCC modernized E-Rate, which is the funding program for K-12 schools to buy technology. Prior to the revamp of the program, E-Rate funded a number of legacy technologies, such as modems, broadband and pagers.E-Rate has now shifted to helping schools build better in-building experiences, with much of the funding directed at Wi-Fi. There’s a certain degree of urgency for schools to get Wi-Fi deployed (I’ll get into the reasons in a bit), but when making a Wi-Fi purchase, K-12 decision makers need to consider more than just connectivity.To read this article in full or to leave a comment, please click here
