The Windows Azure Infrastructure as a Service (IaaS) offering supports running Windows virtual machines and Linux virtual machines in the Cloud. In this article, I provide step-by-step guidance for running a new Linux virtual machine in the cloud using our Windows Azure platform. Wind...
Gartner has been predicting for last five years that cloud computing will have a transformational impact in next 2 to 5 year! So, it is a good time to step back and ask ourselves… I think the answer cannot be given in simple black-and-white term like “Yes” or “No”. Like the answer to ...
If you’re interested in the full list of articles in our “31 Days of Servers in the Cloud” Windows Azure Virtual Machines and IaaS series… “I’m interested in the links to the full series, Kevin.” I was just getting to that. Anyway… here it is. ENJOY! “Hey Kevin.. How come the lis...

While most pundits have fallen in love with public cloud, behind the scenes a variety of technologies and vendors are evolving the will deliver the ultimate clouds, hybrid clouds. Amazon and Google have done a remarkable job promoting public cloud, as VMware, Cisco and OpenStack have ...
Last year, I offered my thoughts on trends and developments that the market would see in 2012. At that time, I felt that we were looking at a continued emphasis on cloud, while mobile and backend integration technologies would rise in prominence within enterprise IT. I think the indust...
I was talking to one of the prominent General Partners at a Venture Capital firm here in Silicon Valley over the holidays…discussing how the Cloud market is evolving. We both agreed that 2013 will mark yet another shift in the evolution of web applications. I personally simplified thi...
Hybrid cloud models continue to outpace pure-public (and pure-private) models for most organizations. There's value in being able to leverage the cloud for a variety of reasons from periodic, expanding compute resources to dev and test environments. Whatever the reason, hybrid models a...
Hybrid-mobile #cloud is the latest attempt at modernizing what remains a relatively unchanged, decades old computing model I was informed via e-mail that the "next big thing" is hybrid mobile-cloud (HMC), which is described as client being a mobile-native application and its server-si...
I was touring what reminded me of the Cheyenne Mountain nuclear bunker – one of the safest places on earth. Except in this case, this was one of the safest places for your enterprise data on earth. “The entrance will open, you will drive in, and an armed guard will be out to escort you...
BYOD was arguably the biggest buzz word of 2012 and is now an unstoppable, user-driven wave which will continue to make a major impact on the IT world in 2013 and beyond. Smartphones, tablets and laptops all come under this category, as well as desktop PCs used remotely from home. BYO...
Marc Andreesen said recently that 2012 will be remembered as the year of SaaS. What he meant is that SaaS has been around for a while, but it came of age this year, with examples of successes such as the Workday IPO. No one questions the significance of SaaS any more. But the year 2013...
Yesterday’s WSJ.com video “Tablet Wars: How Are People Using Tablets?” had a shocking statistic: 98% of the web traffic from tablets comes from Apple’s iPad. Further, most of mobile commerce is from Apple’s iPhone. Translation: No matter what the sales figures for Android, people jus...
HP has been talking and promoting for several weeks (okay, months) their upcoming December 3rd storage announcements from the HP discovery event in Frankfurt Germany. Well it's now afternoon, which means the early Monday morning December 3rd embargoes have been lifted so I can now tal...
Cloud security and cloud compliance are one of the hottest topics in cloud computing. During the course of 2012 we’ve seen many companies, specifically software vendors providing healthcare solutions, migrating or implementing their software in the cloud. While cloud computing brings m...
A good Log Management solution is a solution that collects 100% of the logs 100% of the time, stores all this data and provides intuitive searching and reporting mechanisms to better understand some aspects of the changes applied to the actual data. If this solution provides for alerti...
It is amazing how many open source software companies out there are trying to get hit by the same $1B bolt of lightning that hit MySQL without realizing that the MySQL result is not repeatable. Looking at the current batch of big data high flyers, from TenGen to Cloudera to Hortonwork...
The use of the term ‘Service' is somewhat overloaded. Everyone will have heard or used the terms Business Services, IT Services, Software Services, and now Cloud Services, and yet often there is much confusion and misunderstanding in their use.As my colleague David Sprott suggested in ...
One of our product development senior architects put this together for an introductory presentation on SDN. It's a great list of existing and nascent overlay protocols including encapsulation overhead, bridge and transport types, as well as links to the specifications.
VMware CEO Pat Gelsinger introduced the concept of the Software-Defined Datacenter (SDDC). This builds on the concept that as more and more of the Data Center becomes virtualized (servers, desktops), delivering greater cost-savings and agility to customers, software-defined automation ...
Do you know the computer technology saying, garbage data in results in garbage information out? In other words even with the best algorithms and hardware, bad, junk or garbage data put in results in garbage information delivered. Of course, you might have data analysis and cleaning so...
Normally solid state devices (SSD) including non-persistent DRAM, and persistent nand flash are thought of in the context of performance including bandwidth or throughput, response time or latency, and IOPS or transactions. However there is another role where SSD are commonly used wher...

The English language is well known for its subtlety. Sometimes it’s a delight, but on other occasions it can be very frustrating. If I use the term Gothic Architecture you will immediately understand I am describing a style of architecture that flourished in medieval times. And if like...
After spending time at VMware and Cloud Expo last week, I believe that VMware’s lack of full backing for Cloud Foundry software is holding back the entire PaaS market in the enterprise. Don’t get me wrong, there’s a lot of momentum in PaaS despite how very immature the market is. But ...
In the first wave of solid-state storage arrays, we saw commodity style SSDs (solid state drives) being added to traditional storage arrays. This solution provided an incremental benefit in performance over spinning hard drives, however the back-end technology in these arrays was deve...
I hear people talking about how Solid State Devices (SSDs) have not been successful with or for vendors of storage arrays, particular legacy storage systems. Some people have also asserted that large storage arrays are dead at the hands of new purpose-built SSD appliances or storage sy...
Big Data takes center stage today at the Strata Conference & Hadoop World in New York, the world’s largest gathering of the Apache Hadoop™ community. A key conversation topic will be how organizations can improve data security for Hadoop and the applications that run on the platform. A...

It is a topic of fascination for me that the high-tech world just plain will not stand still. The changes in automotive technology over the last century, for example, do not match the changes in high tech over the last decade. In addition to the expected on-upsmanship that market leade...
There is a growing momentum in the industry that is buzzing about the ‘Open Cloud’. Typically this refers to the open source software aspect of Cloud software, like OpenStack, or other options like OpenNebula. There is also the other dimension of open standards. This will become crit...
There are at least two different meanings for IOPs, which for those not familiar with the information technology (IT) and data storage meaning is Input/output Operations Per second (e.g. data movement activity). Another meaning for IOP that is the international organization for a parti...
A coworker and I put a couple pieces of open source software (OSSEC and Snort) together to respond to certain types of automated attacks we were seeing in our IDS (we use Snort in this case). Prior to this, an engineer would manually respond to alerts by logging into our firewall and b...
Making the most of your virtualized environment means monitoring performance and making changes to optimize performance. The fact is that there are a number of things that can hamper performance in a virtualized environment, and if you’re not looking at all of them you can find yoursel...
Not yet included in the NIST taxonomy of Cloud Computing models is ‘BPaaS’ – Business Process as a Service. Hopefully it soon will be, as although it is the lesser known and discussed of the Cloud categories, it’s the most powerful in it’s ability to directly impact short-term busin...
OASIS, the XML open standards body, is quickly establishing a very powerful leadership role in the Cloud standards arena as well. This includes standards like TOSCA, for Cloud orchestration and therefore a foundation for Cloud Service Brokering, KMIP for unifying enterprise encryption...
This is a follow-up to a recent post about modernizing data protection and doing more than simply swapping out media or mediums like flat tires on a car as well as part of the Quantum protecting data with certainty event series. While I was traveling saw this advertisement sign from D...
One of the key focus areas of our Private Cloud 2.0 series is that the 2.0 part represents the ‘outside world’, even though it is focused on a Private Cloud scenario. This is simply because it is inevitable and one of the valuable features of the Private Cloud approach R...
Microsoft just made a splash in the cloud backup space with the announcement of their Window Azure Backup Service Preview this month. While I'm sure other traditional software and appliance vendors will be partnering with Microsoft to offer a more application coverage, I haven't heard ...
