IDG Contributor Network: SDN and a life beyond the death of the internet

For decades, enterprises have relied on the public internet for business-critical SaaS applications and data traffic. The reason why is pretty simple: it’s cost-efficient, it’s easy to use and it’s already there. Compare that to the logistical, financial and implementation challenges of installing an alternative private network, and it’s clear why enterprises have been pretty content with the internet for their entire digital lives.But, it’s 2017. And, if there’s one thing clear about the public internet today, it’s that it no longer cuts it. Rampant DDoS attacks and other cyber threats posed by hackers, rogue employees and nation-states have not just revealed the security, reliability and transparency cracks in the public internet — they’ve blown them wide open.To read this article in full or to leave a comment, please click here

NSX-Powered Credit Union Shifts Focus to Speed and Innovation

Personal banking sure isn’t what it used to be. Thankfully.

When is the last time you went to a bank? My trips are so infrequent that I actually enjoy the experience as a change of pace. That’s because normally, I get to transfer money or deposit a check not only online, but from my phone. And things in the banking sector aren’t slowing down, they’re speeding up, as new digital upstarts create competition and a pressure to innovate and make customers’ lives easier.

Still, not too long ago, the banking industry was still feeling the shockwaves of the financial crisis. Investments across the industry were tight, meaning more had to be done with less – a story many of us who have had roles in IT can relate to. So when Amy Hysell took on the role of CIO at the Arizona Federal Credit Union (AZFCU), she decided to take a fresh approach. To compete in this fast-moving industry, she stepped back and took a look at on how to enable speed and innovation, while keeping security as the top priority, and also without sacrificing cost efficiency.

Fast forward to today, and a peek at some of AZFCU’s services quickly Continue reading

Worth Reading: NVMe for Data Centers

The Non-Volatile Memory Express (NVMe) specification defines a new method to access solid-state drives (SSDs) over a PCIe bus, and it’s forecasted to grow exponentially over the next few years thanks to its performance advantages and lower latencies compared with legacy protocols (such as SATA). NVMe-enabled storage infrastructures are not only seeing wide deployment, but they’re now entering other data center areas that were once typically reserved for legacy HDDs and SSDs. NVMe has become an agent for next-generation data centers. To understand this evolution, it’s important to review the history and examine some of the new application workloads that are being transformed by this protocol. —Anand Jayapalan @ The Data Center Journal

BGP Attribute : Multi-Exit Discriminator or Known as MED

Today I am going to talk about the other BGP attribute which is widely used for the inbound traffic to come in to your network. MED is generally set by the service provider and the lower value of the MED will be selected as a preference route for incoming traffic into the network.

MED attribute is exchanged between ASs, but a MED attribute that comes into an AS does not leave the AS. When an update enters the AS with a certain MED value, that value is used for decision making within the AS. When BGP sends that update to another AS, the MED is reset to 0.

MED is called as optional non-transtive attribute and the router compares MED attributes for paths from external neighbors that are in the same AS. Hope you got the exact point of the MED use in the BGP enabled network. Lets take an topology and the configuration part of the MED. The topology and the IP addresses showing in this example is taken only for the demo purposes and have no relevance with any of the live or the enterprise network.

Imanis Data focuses on big data backup and recovery

Imanis Data, formerly known as Talena, released version 3.0 of its eponymous backup and recovery platform last week with emphasis on supporting very large datasets that are being generated in the era of big data. The company notes that three out of four companies have experienced a data loss over the last year, which carries an average cost of $900,000 and weeks of downtime. With Imanis Data 3.0, the company claims its backup architecture backs up, recovers and replicates terabyte and petabyte-sized data sets up to 10 times faster than any other solution on the market, minimizing the impact of data loss by reducing costly days and weeks of downtime to minutes and hours and reducing secondary storage costs by up to 80%. To read this article in full or to leave a comment, please click here

What is GLBP and where GLBP should be used ?

GLBP stands for Gateway Load Balancing Protocol. In this article, I will explain where GLBP is used , where it shouldn’t be used with the topologies. GLBP is a Cisco preparatory protocol. In most networks, design requirements might be to use only standard based protocols. If that is the case, GLBP is not a standard […]
