Through http://blog.ipspace.net I landed on this article on acm.org discussing the complexity of distributed systems. Through some good examples, George Neville-Neil makes it clear that creating and scaling distributed systems is very complex and “any one that tells you it is easy is e...
One way or another, all data center networks exhibit at least 6 different functional areas that their operators need to engineer, implement, and operate with a differing set of needs and requirements. Similarly, in one way or another, most of the available SDN and virtualized network s...
Whenever we get to the end of a year we have this tendency to reflect on what has happened in the past year and how we can improve in the coming year. It’s natural to use the change of calendar year as a point in time to think back, even though practically speaking it is usually the mo...
Usually, it is the task of the system administrator in the organization to make its network stable and reliable. His effective operation requires him to know all the information on network: number of hosts, where they are situated, quality of connections between them, their operation, ...
The impact is that it's really difficult to apply access controls to something in the cloud using traditional models that force users and consumers to come to the enterprise data center where that service is hosted first. That has a very negative impact on performance, at a minimum. Si...
If RAID were really not relevant anymore (e.g. actually dead), why do some people spend so much time trying to convince others that it is dead or to use a different RAID level or enhanced RAID or beyond raid with related advanced approaches? When you hear RAID, what comes to mind? ...
Cloud computing seems to still be one of the reigning buzzwords in high-tech these days. Everything is either “in the cloud”, “powered by the cloud”, or some variation on the theme. I remember when hosted email was just that: hosted email. Today, such offerings are considered cloud off...
While many SPM Performance Monitoring users quickly see the benefits of SPM and adopt it in their organizations for monitoring — not just for Elasticsearch, but for their complete application stack — some Elasticsearch users evaluate SPM and compare it to Marvel from Elasticsearch. We...
The premise of cloud is based, like other emergent technologies, at least partially on the notion of abstraction. Cloud providers are able to achieve what appears to be boundless compute, limitless storage and never-ending network capacity by being able to simply "plug and play" the ha...
Recently Arista released a white paper surrounding the idea that having deeper buffers running within the network can help to alleviate the incast congestion patterns that can present when a large number of many-to-one connections are happening within a network. Also known as the TCP i...
The SMB market opportunity is huge. Currently, SMBs represent 44% of the total IT spend worldwide, a figure that Gartner predicts will cross the trillion dollar mark by 2015. That's some serious cash -- yet a market that  traditional storage and virtualization players have pra...
Data centers have matured immensely over the past decade with today’s data centers being greener than ever. Pike Research mentions that the green data center market was worth $17.1 billion in 2012. The green data center economy is expected to grow rapidly throughout this decade. Pike R...
I talk a lot about SDAS (that's Software Defined Application Services) with respect to F5 Synthesis and, well, F5 in general. That's because what F5 Synthesis delivers the ability to easily provision and orchestrate SDAS across a variety of deployment models (on-premise, in the cloud, ...
Software Defined Application Services (SDAS) are going hybrid. . Organizations are turning to cloud not just as an option for applications but also for the network and application services that deliver applications to anyone, anywhere at any time. And not just "in" the clo...
Operationalization (which is really hard to say, go ahead - try it a few times) is a concept that crosses the lines between trends and technologies. Both SDN and DevOps share the notion of "operationalization" as a means to achieve the goal of aligning IT with business priorities, like...
With the blurring of technology lines, the rise of competitive companies, and a shift in buying models all before us, it would appear we are at the cusp of ushering in the next era in IT—the Third Platform Era. But as with the other transitions, it is not the technology or the vendors ...
We are getting into the Halloween spirit here at Plexxi—check out this Plexxi pumpkin carved by our talented marketing manager, Khoa Ma! Jack-o-lanterns aside, we know the thought of navigating trends like the Internet of Things and Big Data can be frightening, especially if you are un...
Although the concepts of continuous delivery are well known, organizations with existing applications looking to implement CD still have a lot to consider. Customer demands aren't the only thing pushing development and operations teams into more frequent software releases. It is also ...
My entire career has been spent finding disruption and cultivating the technologies needed to convert that disruption into real business value for customers. It is with that objective in mind that I am thrilled to join the Plexxi team as Chief Executive Officer, alongside my good frien...
You have probably realized we are having a Big Data kind of week here at the Plexxi blog. And for good reason. The amount of development and change in this big bucket of applications we conveniently label “Big Data”, is astonishing. Walking around at Hadoopworld in New York last week, ...
The Internet of Things is only going to make that even more challenging as businesses turn to new business models and services fueled by a converging digital-physical world. Applications, whether focused on licensing, provisioning, managing or storing data for these "things" will incre...
I am sure our work environment is not all that different from many others. There are large whiteboards everywhere and you cannot find a meeting room that does not have circles, lines and squares drawn on them. Some of our favorite bloggers have written blogs about network drawing tools...
Companies that until recently had never heard of the Internet of things (IoT) are now excited to find that they’ve been IoT players all along. Businesses involved in home automation, security services, vehicle tracking and health monitoring to name a few have been around for a while. T...
Kirk Byers at SDN Central writes frequently on the topic of DevOps as it relates (and applies) to the network and recently introduced a list of seven DevOps principles that are applicable in an article entitled, "DevOps and the Chaos Monkey. " On this list is the notion of reducing var...
With the growing number of CSS Preprocessors like LESS, Sass, Turbine, Stylus and Swith CSS to name a few, it’s hard to decide which to choose for your project, and which will provide the best CSS authoring. Rather than focus on evaluating every CSS Preprocessor (that would simply take...
Certainly, enterprises feel the pressure to transition their networks to next generation architectures like SDN to brace the coming storm that is an app economy. Service providers could provide valuable advice to them on how to do that, if they could yell loud enough over the thunderou...
#HTTP #HTTP2.0 Why that version number is so very important .... It's no surprise that HTTP is the new TCP. Inarguably, more applications are delivered via HTTP than any other. That's including mobile apps, by the way, which are more often than not using HTTP to talk to REST-based API...
#DevOps #SDN And more importantly, what can I do with it?  So within the realm of software-defined (everything) and DevOps one can find lengthy (and often in depth) discussions on the relevance and indeed importance of programmability to both. In the case of SDN, programmab...
When SDN made its mainstream debut at Interop in 2012, there was quite a bit of excitement tempered by the reality apparent to some folks that technical limitations would impact its applicability above layer 2-3 and, perhaps even at layers 2-3 depending on the network. But even then w...
#SDN #DevOps #Agile A syzygy is an astronomical term that describes the alignment of three celestial bodies within a gravitational system. The alignment of three celestial bodies (app dev, ops, the network) within a gravitational system (IT). The data seems to show some alignm...
I remember when we first started talking to customers about the concepts of applications driving networks, about 3 years ago (This was a very different conversation from other networking era’s where we talked about ‘intelligent’ networks that could better understand and adapt to applic...
With the capability to reduce both CapEx and OpEx, it’s easy to see why the SDN-NFV trend has taken hold in the hosting and mobile industry. Early use cases include network virtualization from cloud service providers and enterprise data centers, bandwidth calendaring and network tappin...
Executives charged with building business-driven applications have an extremely challenging task ahead of them. However, the cavalry has arrived with useful tools and strategies built specifically to keep modern applications working efficiently. We partnered with Gigaom Research to ca...
August 2014 Server and StorageIO Update newsletter By Greg Schulz Welcome to the August 2014 edition of the StorageIO Update (newsletter) containing trends perspectives on cloud, virtualization, software d...
We’re a few short days away from VMworld’s return to the Moscone Center in San Francisco. Our team will be in booth 747 (hence the jumbo-jet below),  to demo our products and answer any questions you might have about our products – including the new datacenter transport fabric and Big ...
