Disaster Recovery with VMware NSX-V and Zerto

Note, this is a reposting of the blog that I initially posted here on humairahmed.com. In a prior blog, VMware NSX and SRM: Disaster Recovery Overview and Demo, I described and demoed how VMware NSX and SRM with vSphere Replication combined provide for an enhanced disaster recovery (DR) solution. SRM also provides additional integration with NSX when Storage Policy Protection Groups (SPPGs) are used by providing the ability to automate network mappings. One of the great things about the NSX-V platform, is it can be used with any DR orchestration tool that supports the VMware vSphere ESXi hypervisor. Some of the tools customers are using with NSX include VMware SRM, Dell EMC RP4VM, Zerto, and Veeam. As SRM was discussed and demonstrated in a prior blog, Zerto and NSX together is explained in more detail below.  Continue reading

Wait, what happened to my choices?

This weekend, I experienced one of those moments that make me question the value of information technology. My trusty windows phone, for whatever reason, failed. Given I was traveling in less than 24 hours, I needed to find a replacement. So I traipsed to the local phone store, and was told “I’m sorry, we don’t sell windows phones. They aren’t popular enough.” So there I stood, like the shopper in the proverbial aisle of cereal, trying to choose which new phone to get.

After staring at all the different phones for a while, it dawned on me that the apparent variety is fake. I really only had two choices.

The first is the iPhone. The iPhone is a throwback to the late 1990’s, at least one generation behind current hardware, and with a user interface that falls into the “cute retro gamified Windows 3.11/Xerox Star” sort of thing. Getting anything done requires jumping through multiple hoops. There is no way to pin anything you use on a regular basis to the screen, no information available without entering an app, the icons are tiny candies, etc. Sorry Apple fanfolk, but Apple hasn’t innovated in at least 10 years in Continue reading

Worth Reading: What if everything you know about passwords is wrong?

Every time there’s a notable cybersecurity breach, someone (even me) writes a comprehensive primer on the proper way to create “secure” passwords. Lather, rinse, repeat. Until a few years ago, everyone (including me) based their password advice on a 2003 paper from the National Institute of Standards and Technology (NIST), with the catchy title “NIST Special Publication 800-63.” The paper recommended that passwords be cryptic, contain special characters, and be as close to nonsense as possible. —Shelly Palmer

Test Drive Docker Enterprise Edition at VMworld 2017

VMworld 2017

Docker will be at VMworld 2017 next week (August 27-31) in Las Vegas to highlight new developments with Docker Enterprise Edition (EE), the only Container as a Service (CaaS) platform for managing and securing Windows, Linux and mainframe applications across any infrastructure, both on premises and in the cloud.

Stop by Booth #1206 to learn more about:

  • How VMs and containers work together for improved application lifecycle management
  • How containers and Docker EE can help IT with day-to-day maintenance and operations tasks
  • How IT can lead modernization efforts with Docker EE and become drivers of innovation in their organizations

Just as VMware vSphere simplified the management of VMs and made virtualization the de facto standard inside the data center, Docker is driving containerization of your entire application portfolio with Docker EE and helping organizations like yours to achieve their cloud and app modernization goals without requiring you to change how you operate.

Test Drive Docker EE in the Booth

Don’t miss the chance to get hands-on experience with Docker with our in-booth labs. Led by Docker experts, you will get to see for yourself how Docker brings all applications—traditional and cloud-native, Windows and Linux, on-prem and in Continue reading

Amazon Temporarily Discounts Echo from $179 to $100 – Deal Alert

By now I'm sure you're familiar with Amazon's Echo device. Amazon Echo comes in both white and black, and is a hands-free speaker you control with your voice.

How Google is speeding up the Internet

Engineers at Google have developed a new algorithm to speed up TCP, the main transport protocol for traffic on the internet, by optimizing the speed at which traffic is sent so it doesn’t clog up the available routes. They say their acceleration method, called bottleneck bandwidth and roundtrip (BBR) propagation time, measures the fastest way to send data across different routes and is able to more efficiently handle traffic when data routes become congested. Google is already using BBR to speed up its YouTube traffic, and last month the company made BBR available in its Google Cloud Platform. Google says implementing BBR sped up the already highly-optimized YouTube traffic by 4% on average, and as much as 14% in some countries.To read this article in full or to leave a comment, please click here

Advancing Privacy Protection with the GDPR

A game-changer

The road towards implementation of the new European GDPR (the General Data Protection Regulation) has been a long one, even though public awareness of its impact, especially outside of Europe, is only now really starting to take hold. This game-changing piece of EU legislation will require companies to fundamentally change how they process and use personal data (broadly defined) they receive from EU citizens, including through consent and data handling agreements with their customers, supply chains, and vendors. It will come into effect on 25th May, 2018, and will have tremendous reach, touching on all business sectors. More than that, the GDPR has extra-territorial scope and will apply to any business that processes the personal data of European users, irrespective of whether that business has any physical presence in the European Union.

The aim of the GDPR, which will replace the currently applicable European Data Protection Directive of 1995, is to both meet the challenges of globalization and address dynamic new products and services, while also trying to create a future-proof framework that will comfortably accommodate emerging technologies and scenarios, including the Internet of Things. It is also a response to Europeans’ growing concerns over the control and Continue reading

BrandPost: How to Know if An Active-Active Architecture Right for You

Software defined WANs (SD-WANs) have gained market momentum so quickly because their value proposition is multi-faceted. Some enterprises have looked to SD-WAN as a way to dramatically lower network transport costs, while others are building SD-WANs to automate network operations. One of the more common use-cases I have seen is to shift toward an “active-active” architecture.ACTIVE-ACTIVE WAN ARCHITECTUREHistorically, WANs are built on the concept of “active-passive”, where a branch can be connected using two or more links, but only the primary link is active and passing traffic.  In this scenario, the backup connection only becomes active in the event the primary connection fails. While this might seem sensible, it’s highly inefficient as enterprises are paying for far more bandwidth than they are actually leveraging. This inefficient architectural design is driving increased interest in active-active configurations.To read this article in full or to leave a comment, please click here
