Taking a look a what I was using and paying WordPress.com for I felt it no longer made sense to keep using the service. After looking at some alternatives I decided upon using GitHub Pages to host my blog. It will force me to use a certain toolset, and it’s free! :-)
My first job in IT, many moons ago, was at a company called MOTEC, it was a subcontractor of Telenet, one of the biggest ISPs in Belgium. We were responsible for building the cable based telephony systems that their customers used to make phone calls over the tv distribution network.
If you look at the consumer applications we interface with on a daily basis, things like Facebook, Google, Twitter,… these all tend to be very easy to use and understand, typically little to no explanation is needed on how to use them, you simply sign-up and you get going.
As I’m sure you’re tired of hearing by now IT is typically divided in multiple silo’s which don’t always see eye to eye. Sometimes people are afraid of needing to adjust perceived best practises in their own domain to better collaborate with the rest of the organization, in many cases though it’s simply a matter of not understanding each other because you are not speaking the same language.
VMware has lot’s and lot’s of customers, running lot’s and lot’s of workloads, both dev and test workloads and production workloads, you know like, super duper important stuff that cannot, under any circumstance break.
I remember when I was first asked to install ESX 2.x for a small internal project, must have been somewhere around 2004-2005, I was working at a local systems integrator and got the task because no one else was around at the time. When researching what this thing was and how it actually worked I got sucked in, then some time later when I saw VMotion(sic) for the first time I was hooked.
VMware just announced some additions to it’s public cloud service, vCloud Air, one of the additions is advanced networking services powered by VMware NSX. Today the networking capabilities of vCloud Air are based on vCNS features, moving forward these will be provided by NSX.
VMware NSX is a network virtualisation and security platform that enables inclusion of 3rd party integration for specific functionality, like advanced firewalling, load-balancing, anti-virus, etc. Having said that VMware NSX also provides a lot of services out of the box that depending on the customer use-case can cover a lot of requirements.
I will be presenting a session on VMware NSX at the 21st Belgian VMUG meeting on the 21st of November in Antwerp. You can register for it here.
A killer application
What are we trying to solve?
As announced during EMC World 2014 SAP now supports running production SAP HANA on vSphere 5.5 further delivering on VMware’s “Apps love vSphere” premise unveiled at last year’s VMworld conference.
Yesterday at VMware’s Partner Exchange (PEX), VMware announced that it is joining forces with Google to modernize corporate desktops for the Mobile Cloud Era by providing businesses with secure, cloud access to Windows applications, data and Desktops on Google Chromebooks.
Server virtualization has increased the amount of server to server network traffic, commonly described as east-west traffic. Let’s assume that you have 2 VM’s living on the same host and both VM’s are in different layer 3 networks, in a traditional network traffic flow would be:
I haven’t been blogging a lot the last couple of months, I’m still trying to drink from the water-hose having recently started at VMware, and of course customers come before blogs…
vSphere Replication is VMware’s hypervisor (as opposed to storage array) asynchronous (minimum 15 minutes) based replication solution that works at the virtual machine (VMDK) level whereas storage array replication usually works at the datastore (VMFS) level. (One of the reasons why vVols will be interesting going forward).
I recently joined VMware as an SE, one of the reasons that motivated and influenced my decision to join is a thirst for technology, at VMware you get to work on such a broad and interesting technology stack that anyone is bound to find one or more things that are deeply interesting.
Riverbed recently released the latest edition of it’s cloud storage gateway, both upgrading the software and providing new hardware options.
As an SE at a WAN optimization vendor I’m often faced with the following comment when meeting a new customer: “We don’t need WAN optimization because my ISP is offering me a great deal when I upgrade my bandwidth between A and B”.
When using VMware View, or any other VDI based solution for that matter, across a Wide Area Network you need to think about certain limitations inherit in this setup that can potentially limit the user experience for your remote users.
In the summer of last year Amazon announced Amazon Glacier, an extremely low cost storage service designed for data archiving and backup.
Software defined anything (SDx) is the new black.
If you ask an IT administrator to draw his/her ideal IT architecture you’ll probably get a picture of a big consolidated datacenter with all remote branches connecting to it without any locally installed servers/storage.
As mentioned in my previous post Riverbed has a joined SaaS optimization solution with Akamai called Steelhead Cloud Accelerator. In this blog post I will show you how to use this technology to accelerate your salesforce (people and the application).
One of the prerequisites for WAN optimization is that the traffic we are attempting to de-duplicate across the WAN is not encrypted, we need “clear-text” data in order to find data patterns so de-duplication is most optimum.
One of the coolest, in my humble opinion of course, solutions I was able to work with when I was at Dell, was the CAStor Object Storage system from Caringo, OEM’ed as the Dell DX6000.
Riverbed has recently released version 2 of the EX platform software, this includes RiOS 8 and Virtual Services Platform v2. VSPv2 runs VMware ESXi 5 as it’s hypervisor layer and as such can be managed by VMware vCenter.
Riverbed Whitewater allows you to connect your on-premise backup and archive environment to a public cloud storage provider like Microsoft’s Windows Azure.
In this post I wanted to explore how you can accelerate file storage (using CIFS as an example) over a wide area network and why it traditionally does not work for block storage (using iSCSI as an example). First let’s look into some of the (greatly simplified) common differences between the types of storage.
