One Platform, Any Application – and Getting There with Cloud-Native

February 2, 2015
By

Today’s an exciting day for VMware as we hold our biggest launch ever for a plethora of new products. While Pat and Ben are unveiling all the new features, I wanted to give the Cloud-Native Apps perspective.  As you guys know, our focus is on helping customers develop next-gen applications and operate them in production. It’s about helping our customers get applications to market faster.  VMware’s recent product announcements provide key technology building blocks to realizing this goal. VMware’s already released vRealize Code Stream – an exciting new product that provides governance and automation of build, test, and deploy pipelines for applications. Ultimately it allows our customers to get newly tested, proven application updates to market as quickly as possible. Last month,...

EVALExperience – Yet Another Reason To Be A VMUG Advantage Subscriber

January 15, 2015

One of the things that excited me most when I joined VMware was how passionate and knowledgeable our user community is. After I joined, I remember getting on a plane once. I was wearing VMware apparel (aka ‘schwag’) and carrying a VMware laptop bag (aka more schwag, and yup I am all in on wearing/touting the logo). As I walked through the cabin, a gentleman looked up at me and said, “Are you just wearing the clothes or do you actually work for VMware?” I replied that yes, I worked for VMware. He said, “Thanks.  I love your products!” I’ve worked for many companies, and worn their wardrobe, but this was one of the first occasions that doing so solicited such a response… and...

Running HPC Applications on vSphere using InfiniBand RDMA

Running HPC Applications on vSphere using InfiniBand RDMA

Looking back on 2014, this was the year in which we made significant strides in assessing and addressing High Performance Computing (HPC) performance on vSphere. We’ve shown that throughput or task-parallel applications can be run  with only small or negligible performance degradations (usually well under 5%) when virtualized — a fact that the HPC community seems to now generally accept. The big new thing this year, however, was the progress we are making with MPI applications — specifically those applications that require a high-bandwith, low-latency RDMA interconnect like InfiniBand. As I mentioned in an earlier blog post , we generated a great deal of RDMA-based performance data about HPC applications and benchmarks this past summer due to the hard work...

Virtualized High Performance Computing in 2014

Virtualized High Performance Computing in 2014

As we complete another circuit around the sun, it’s time again to make some predictions about what we’ll see over the course of our next orbit. Since my work in the Office of the CTO focuses on High Performance (Technical) Computing, I’ll focus there. But before looking ahead, let’s take a minute to look back and see how I did with my predictions last year . 2013 Predictions Scorecard Last year, my predictions related to public cloud, private cloud, RDMA in the cloud, virtual machine evolution, and HPC acquisitions. My biggest “miss” was also my most specific prediction — that Amazon would announce RDMA support in 2013 in order to better support latency-sensitive MPI applications. They did not,...

Hadoop Performance on vSphere 5.1

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...
