Relevance of POSIX in the Big Data Era?

February 27, 2015

Let’s start with a thought exercise: imagine your application issues a write() call followed by a read(). What would you expect to get back in the read operation? Here are your options: Always get back the latest update Get back either the latest update or the previous value, but never partial updates Always get back the latest update if the read is issued from within the same session Once the latest value is returned by the read, the subsequent reads will never return the old stale value i.e., monotonic guarantee Bounded staleness i.e., reads issued after a given interval will always see the latest updates And so on… All the options listed above are valid — the correct answer depends on the internal implementation...

Looking Into the Crystal Ball: 2015 End-User Computing Technology Predictions

January 16, 2015
By

By Noah Wasmer, VP of Product Strategy, End-User Computing, VMware Without a doubt, 2014 has left an indelible impression on the technology landscape.  Every major software and hardware player, including VMware, has continued to drive towards mobile and cloud for end-user computing. Before diving into the future predictions for 2015, let’s reflect on 2014 innovations as a basis of what’s to come. In exploring the end-user computing landscape, one would be remiss to not explore the platforms that dominate our everyday computing experiences – namely Apple, Google and Microsoft. Apple –Apple has not been shy about expanding into the enterprise, announcing a new strategic partnership with IBM and offering new business applications targeting vertical markets to support business mobility.

Hadoop Performance on vSphere 5.1

We’ve just published a third Hadoop performance paper, written by VMware performance expert Jeff Buell, which looks in detail at the relative performance of a bare-metal 32-node Hadoop cluster compared to a range of virtual clusters with up to 128 VMs. The executive summary is that while we saw a 13% performance degradation in a head-to-head comparison of a 32-node physical cluster against a 32-VM virtual cluster (one VM per host) running on the same hardware and running the same tests, virtualized performance can be increased significantly — to the point where virtualized Hadoop actually runs a bit faster than physical — by increasing the number of VMs per host. We’ve seen this effect before with Hadoop...

2013 Predictions: When Worlds Collide

2013 Predictions: When Worlds Collide

It’s time again to dust off the crystal ball, cast the yarrow sticks, read the tea leaves, and share some thoughts about where the IT world is heading over the next twelve months and beyond. Because my focus at VMware is on High Performance Computing (HPC), I’ll confine my prognostications primarily to the growing area of overlap between mainstream Enterprise Computing and HPC — places where each world can benefit from the other in important ways. Before I start, let’s get one no-brainer prediction out of the way: 2012 will be remembered for Nicira , and not Nibiru . Yes, software-defined networking ( SDN ) will trump planetary collisions and the...
