This is a follow-up blog that is part of a series of 2015 cloud predictions. The first one, entitled When the Walls Come Down, had the following as the central thesis: In 2015 the perceived costs of cloud migration for existing production apps will drop by more than 50%; it will trigge...
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...
The notion of a database silo – that is, a single database that contains everything and operates in isolation – is a rapidly fading concept in most companies. Many use multiple databases to take advantage of the different range of functionality, from their transactional store, to cachi...
The pace of innovation in such big data-driven targeting technology is advancing unabated. There is so much noise in today’s omnichannel world that anything a marketer can do to get your attention is welcome – and furthermore, the more information they can collect about you, the better...
It does not take much to understand the benefits of the DevOps culture, processes, and tools. However, implementing DevOps in your organization is not as obvious and usually involves more than simply setting up tools. You have to convince team members, map old processes to new, and ma...
Today, all the discussion on Big Data centers around “static data” in a data lake (old Data Warehouse) accessed by BI tools or SQL on Hadoop (Hawk, Impala) or Map/Reduce algorithms (MapR) for analysis. This is looking at historical data and finding trends. Some new tools are trying to ...
HP analyzes its own vast data warehouses to derive new insights for its global operations, extensive supply chain, sales organization, global marketing groups, and customers.
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...
The tendency of most companies is to talk strategy and vision. Almost every technology company can paint a future that is somehow more elegant based on their product’s fit into customer plans. And, as a sales leader, if you find a company whose vision you find compelling enough to insp...
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, ...
Putting on a rock show is like piloting the Millenium Falcon – it’s simultaneously the fastest ship in the galaxy while being a “piece of junk.” The stage lights are so hot you start to sweat immediately, hoping those Jager-bombs are escaping through your pores and delaying the impend...
This year like last year, XebiaLabs polled Fortune 1000 companies in banking, manufacturing, healthcare, government and IT, interviewing DevOps teams and everyone from QA to C-level suites. More than 1,000 people were asked to share their perspectives on software delivery trends. Last...
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...
In a recent post I posted on DevOps.com, I suggested the term DevOps as a Service (DaaS). Personally I am not a fan of the term. Mainly because DevOps is not a ‘Service’. It is an approach to achieve business objectives by adopting a set of capabilities, namely: Continuous Business Pla...
It's hard to miss the world of opportunities that data collection and analysis have opened up. But how can you avoid having information overload? It takes a lot of will power, in our data obsessed world to say "too much!" However, there are many ways where too much information is dest...
DevOps is no longer considered a fad by those working with the latest development tools. Now, DevOps emphasizes people and processes as much as the cool tools, and there are many different approaches to bringing them together. If you Google search for “DevOps flow,” you will find lots...
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...
Machine-to-machine (M2M) technology and the resulting Internet of Things are leading us inexorably toward everything-as-a-service (XaaS). As more things get connected, the range of service opportunities expands. And as those services are presented online, they become available for use,...
Consider that the Age of the Cloud has precipitated a new agent concept which is lightweight, deploys quickly, and goes in virtually undetected with zero configuration. These agents are built with a survival mode in mind including a self-healing option for hands-free maintenance. At t...
Now while we kidding around about naming this wall the "MacVittie-Roberts wall of DOOM", we weren't kidding about the need for better performance monitoring in production. After all, to definitely say that application performance is faster requires that we've measured performance after...
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...
When Instagram was sold to Facebook in 2012, it employed only 13 people and maintained over 4 billion photos shared by its 80 million registered users. Internally, Instagram was a small business. Externally, it was a web monster. Filling the gap between those two contradictory perspec...
Enterprise applications are increasing in complexity, with multi-tier and distributed applications being the new standards for dealing with high-volume, high-scale requirements. In many development environments, the ideal scenario is to enable DevOps teams to manage dev/test environmen...
In my first post, I discussed how software and various tools are dramatically changing the Ops department. This post centers on the automation process. When I was younger, you actually had to build a server from scratch, buy power and connectivity in a data center, and manually plug a...
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...
When I took my operating systems fundamentals course in college I was taught that an operating system provides very specific capabilities that provides users with access compute resources for building and running applications. Over time as networking capabilities and bandwidth increase...
DevOps is a discontinuous innovation in the way organizations develop and deliver software. And as with any new discontinuous innovation, the implication is that creative destruction will follow. Companies that hold on to legacy business and technology models, without pursuing the ev...
#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...
I ran across this quote a while back, and was awestruck at its profundity. I keep it on a list of quotes that I look to for inspiration. To think that the guy who invented the theory of relativity views the world in this way, trying to distill extremely complex ideas down to their simp...
Logging as part of the continuous delivery process can help your teams move faster and build a product that your customers really love. Over the last years Continuous Delivery has gained a massive following with many development teams embracing the style. Companies have chosen (as wit...
Throughout the development cycle of new features and functions for any network platform (or probably most other products not targeted at the mass market consumer) this one question will always come up: should we protect the user of our product from doing this? And “this” is always some...
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...
While some might still be focused on SDN with an OpenFlow-style twist, 30% of the organizations in our survey this summer (report forth coming, I promise!) were looking at SDN to improve time to market. Of those, 73% considered an API-enabled infrastructure to be important to very impo...
#SDN #DevOps Stateful is not stateless. And vice-versa.  
As one of Heroku’s beta users I had the chance to check out the new Heroku button gallery last week. I must say I was very pleasantly surprised. Over the past few years, it’s fair to say Heroku have nailed their PAAS offering. They are one of the few PAAS providers to truly succeed in...
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...
Software-defined networking is fundamentally about two things: the centralization of network intelligence to make smarter decisions, and the creation of a single (or smaller number of) administrative touch points to allow for streamlined operations and to promote workflow automation. T...
