What Happens in Vegas…

What happens in Vegas…. Greetings from CA world in Las Vegas! In this post, I want to ensure that some things, which don’t need to stay here, don’t! I had the pleasure of watching Barry Becker (Vice President, GTS Systems Services Center of Competency at IBM) and Ashok Reddy (General Manager of the CA mainframe Business) announce a new teaming approach. They announced joint support for a series of initiatives starting in North America, focused around IBM’s “Cloud Managed Services on z Systems” (I am going to call it the “zCloud”, IBM’s strategic cloud service for the mainframe). Ashok and Barry first talked about the move … Continue reading What Happens in Vegas…

LinuxONE and large VM’s – a Linux Infrastructure performance perspective

At VM Ware World mid-last year HP, VM Ware and IBM Storage got together to talk about some findings they got from internal benchmarks, the even went so far as to produce, a whitepaper was published by the VMware performance folks describing a scalability test of running multiple RedHat Enterprise Linux 6.5 virtual machines under vSphere 5.5 on a 240 core HP Superdome X. While the focus of the study, known as Project Capstone (*), was on the scalability of multiple VMs, we thought it would be interesting to compare how an IBM LinuxONE Emperor machine would perform, using a … Continue reading LinuxONE and large VM’s – a Linux Infrastructure performance perspective

A Look at Docker and Portability

Often enough, Docker is mentioned in one breath with portability. However, there are two dimensions of portability: first, running a container on any system of the same platform. Here, Docker really simplifies deploying applications on any system (of the same instruction set architecture). From a Linux on z Systems perspective, the second aspect of cross platform portability is more interesting: portability across platforms. Often enough, getting a container to run on z is not a big deal, but sometimes it is. Let’s decompose this: Start with the Docker interface: whether that refers to the CLI or REST API, it is … Continue reading A Look at Docker and Portability

A busy week in Linux

Red Hat Summit was a great success with over 5,000 people attending, up from 4,300 last year.  In  a tough economy with strict expenses policies the norm, getting 5,000 to turn up in Boston for almost a week is no mean feat!  So why the buzz? Well, Open Source is going mainstream in data centres, over the last 20 years Linux has gone from an anti-movement to Windows to in most cases the platform of choice for modern business applications. At the IBM booth at the conference it was a stream of attendees from numerous household names, yes there was the … Continue reading A busy week in Linux

2nd wave of cloud…

So the world of Cloud Computing continues to evolve on a almost daily basis, but what specific event has forced pen to paper… or virtual pen to paper at least.  Well the exit of RackSpace from the IaaS market to me was a major event in the evolution of the cloud and the commoditization of what I call the first wave of cloud, namely Simple IT-aaS. If one of the hiperscale darlings of the IaaS space can no longer make sufficient margin from this sector then what hope have tier 2 and 3 player got for local markets or specific industry … Continue reading 2nd wave of cloud…
