From the Blogosphere

I will admit I have been a strong opponent of those listing roles and organizations as DevOps. Primarily because DevOps is a way to do something and creating a role DevOps Engineer is just putting lipstick on the pig for those looking to hire a Linux Sysadmin or infrastructure script c...
Perhaps you may have read that Brazil recently abandoned their controversial proposal that would have forced global internet companies to store data on Brazilian users inside the country. While many of us can surmise a number of reasons the viability of such a measure might have been u...
Windows 8.1 has a lot to offer Business, probably one of the bigger improvements is the inclusion of Hyper-V in the client. This provides support for several scenarios including: Test Lab: This is what I use it mainly for to test all the wickedly cool technologies in Windows Server ...
After five days (and eleven meetings) with new customers in Europe, Russia, and the Middle East, I think time is right for another refinement of in-memory computing's definition. To me, it is clear that our industry is lagging when it comes to explaining in-memory computing to potentia...
A survey from the Vanson Bourne market research agency (with CA) late in 2013 indicated that 39% of those surveyed had adopted some form of DevOps and 27% were planning to do so in the near future. Despite this being such a hot topic in the IT sector, and with a high level of take-up, ...
When applications crash due to a code quality issues, the common question is, "How could those experts have missed that?" The problem is, most people imagine software development as a room full of developers, keyboards clacking away with green, Matrix-esque code filling up the screen a...
This post is following up on last week's post, "The Inevitability of Idle Resources", in which I mentioned the importance of ensuring not only that resources are available when you need to provision a new service to scale but that the resources available match the needs of the service....
Once you learn the definition of shadow IT, it shouldn’t be too shocking to learn how widespread it is at companies large and small all over the world. I hate to assume, but the odds are, that you yourself have used a non-IT approved SaaS option for the same reason as everyone else, m...
There are people who take life slowly, accept it on its terms, meditate, read about meditation, and internalize books like "Wherever You Go, There You Are," a bestseller by a guy with a hyphenated name. I'm more of a Malcolm Gladwell fan -- Outliers or his newest book “David and Goliat...
Proponents of pure software infrastructures often point to rapid provisioning (like right now, push a button and blam! Instant scale) as one of the reasons to "go software." Superficially this is true. If your infrastructure is all software (or virtual, if you prefer) then when you nee...
The term "Big Data" is quite possibly one of the most difficult IT-related terms to pin down ever. There are so many potential types of, and applications for Big Data that it can be a bit daunting to consider all of the possibilities. Thankfully, for IT operations staff, Big Data is mo...
Google’s pursuit of self-driving cars has been well documented over the years. The promise of fleets of self-driving vehicles that could potentially make driving safer while simultaneously shortening commute times makes it one of the most attractive futures technologies around. But whe...
Today PerspecSys announced the results of a survey conducted at the 2014 RSA Conference concerning the attitudes and policies of organizations towards cloud-based security. After polling 130 security professionals on the show floor of the RSA Conference, PerspecSys found that "an overw...
LIn 1974 a specification was developed that would, eventually, launch what we know of as "The Internet." That specification was TCP and though it is often overshadowed by HTTP as the spark that lit the fire under the Internet, without TCP HTTP wouldn't have a (transport) leg to stand o...
Disaster recovery is about being able to get your business back up and running as quick as you can after the disaster happens. Throughout this series, my teammates have focused on the Infrastructure side of the house, servers, virtual machines, etc. You can see the full series here: D...
The goal of a load test is to replicate the traffic & conditions your app experiences in production as realistically as possible As a tester, you understand how important it is to create the most realistic load test possible to provide confidence that your web application won’t fail i...
Back in the noughties I made the conscious decision as a Storage guy to immerse myself into what was being termed server virtualization and understanding the product offerings of a relatively new company named VMware. To this day I remember the incredulous looks and responses I receive...

#sdas #webperf New TCP algorithms and protocols in a platform net improved performance for apps

The original RFC for TCP (793) was written in September of 1981. Let's pause for a moment and reflect on that date.

When TCP was introduced applications on "smart" devices...

If the future of federated controllers is based on service layering, then how do multiple controllers manage the same device? Is there a requirement for state synchronization? Do they share information about device operation or configuration? Is there a need for controllers that are ma...
Incredibly it's that time of year again when voting commences for the Top Virtualization blog of the year and I've just been pinged a note that The SANMAN blog has been nominated again for voting! Last year's nomination was also a nice surprise as the blog ended up being a New Entry in...
In part one of this three-part series I summed up how the way we produce and consume data has evolved over the last three decades, creating a need for new storage methodologies that can help enterprises store and effectively manage massive pools of data. I concluded that the immutable ...
As SDN moves closer to large-scale deployments, the issue of controller scaling is becoming a hotter topic. The consensus seems to favor some form of distributed cluster environment, likely in the form of federated clusters. But how should these federations be formed? The first thin...
If you are new school or old school, then will you be stuck on those school's of thought or advanced to the current and future schools? From the old school folks you will hear things along the lines of that is how we do or did it. Also you might hear things along the lines of lets use...
As promised in our earlier post, here are the final predictions we saw making the rounds in the blogosphere at the start of the year. Many are predicting that Microsoft will get more serious about the cloud. Amazon dominated the cloud news in 2013, but 2014 will be a good year for Mic...
A lot of security-minded folks immediately pack up their bags and go home when you start talking about automating anything in the security infrastructure. Automating changes to data center firewalls, for example, seem to elicit a reaction akin not unlike that to a suggestion to putting...
What started out as a mechanism to program flows into network switches and routers in a standard way is evolving into a full blown forwarding engine programming and management specification. In the latest version of the spec (1.4, released in October 2013), the abilities exist to confi...
It is exceedingly difficult for individuals to match their capability to perform a job or function exactly with their experience in that role. For the upwardly mobile, being promoted into a new challenging role means heading into something with the capability but minus the experience. ...
Pundits, owing to SDN still being very young and not widely adopted, continue to put forth treatise upon treatise as to why organizations should be falling over themselves to go out and get themselves some SDN. Now. Not tomorrow, today. One of the compelling reasons to adopt is to add...
I’d love to take a poll (feel free to share your opinion in the comments section below) on whether software should be considered a living organism in the purist biological sense. Sure, software is made up of code instead of cells, and it may have trouble finding a home in the classic t...
SDN is almost universally associated with disruption; the general consensus being that it is a significant departure from the way networking has been handled for decades. Insofar as SDN marks a major architectural shift, it absolutely should be considered a disruption. But how does dis...
It is human nature to try and relate new information and new ways of doing things to something that we know, something we are familiar with. Often when we talk about the way we fit traffic onto a Plexxi mesh network, the reaction is “I know what you mean, you are doing traffic engineer...
Many IT teams are looking at virtualization in the Cloud where enterprise-level storage is kept in “pools” often hosted by vendors who specialize in virtual storage. Most commonly, the data and additional space is accessed via a web-based API. Coraid offers a unique storage management ...
With the cloud in its sights as a fast-track strategy for growth, SHI International Corp. has partnered with Zetta.net to round out its expanding portfolio with an enterprise-grade cloud backup and disaster recovery (DR) solution. SHI, which has transformed over the years from a $1 mi...
Estimates based on reports from Google put the number of daily activations of new Android phones at 1.3 Million. Based on reported data from Apple, there are 641 new applications per day added to the App Store. According to Cisco's Visual Networking Index, mobile video now accoun...
After an interesting career in the corporate world and an independent, I am making another change. Starting next month, I will take up the role of Research Manager in the Platform as a Service Practice with International Data Corporation (IDC). After spending 5 years evangelizing clou...

#SDN #Devops #LineRate When you put software into the data path there are some things it better have to make sure it doesn't become a liability

The software-everywhere drumbeat continues to resound across the entire industry. Experts assure us that software can perform as w...

One of the questions we hear most frequently is “how do I get my data into the cloud?” For many organizations, the benefits of expanding on-premise data storage to include hybrid cloud storage have begun to resonate, but they struggle to get started as they determine how to get move da...
There are a plethora of tactics used to test applications as they move to production. For example, as a developer I've created data and captured data for testing and - my favorite - ignored testing altogether. After all, it worked on my machine. The reason there are so many tactics ...
Not entirely unexpected, the optical capabilities in our switch have provoked questions from customers and potential customers on whether the Plexxi solution could be used to create campus, metro or even long distance multi site fabrics. The answer to that question is a resounding yes,...
BYOD may be the word of the day on the street but underlying the "come as you are" approach to computing is a variety of technology that enables organizations to confidently take up the gauntlet thrown down by users to support their demand to use the computing platform of their choice....
