For all the buzz-words and high-flying markets out there today, the truth of the matter is that at this point in time, IT is driven by speed. How fast can I spin up an image? How fast can I integrate the changes in my app? How fast can I test prior to deployment? How fast can I go from...
Containers allow for compute processes to be isolated from each other and portable, but not all applications and solutions are run only in the compute layer; many require the use of some storage. Deployment of software-defined storage can be the first step in this evolution, providing ...
There’s really an unlimited number of ways in which programmability in the network (data path scripting) can solve problems, address risk, and simplify architectures. In the area of DevOps it can be used to facilitate continuous delivery (CD) initiatives by supporting the implementatio...
Over the last few years we’ve seen just about every part of the data centre move towards virtualization and software. First we virtualized desktops, then storage, then even our security tools. So when the idea of Software Defined Networking (SDN) started being floated around, it wasn’t...
Most of the time when we think about (and honestly, talk about) “programmability” of app services (in the network) we end up illustrating its potential by using load balancing or perhaps app security. That’s because the possibilities seem endless for those services, with countless exa...
Jared Cook, VMware’s Lead Strategic Architect, Office of the CTO, visits #F5Agility15 and shares how F5 and VMware solutions can be used together in an orchestrated fashion to enable customers to spin up applications on-demand, and provision F5 software defined application services tho...
Services providers have traditionally organized the management and operation of different technologies into several teams with very specific domain knowledge. These teams have been staffed with specialists looking after routing, network services, servers, virtualization, storage area n...
"ProfitBricks was founded in 2010 and we are the painless cloud - and we are also the Infrastructure as a Service 2.0 company," noted Achim Weiss, Chief Executive Officer and Co-Founder of ProfitBricks, in this SYS-CON.tv interview at 16th Cloud Expo, held June 9-11, 2015, at the Javit...
The best of virtualization and the best of hardware integration are creating the preferred on-ramps to the cloud. IT organizations are well enamored of virtualization. They are so into the trend that many have more than 80 percent of their server workloads virtualized. They like hybri...
If you’re curious about learning the difference between Software Defined Networking (SDN) and Network Function Virtualization (NFV) and how they relate, here’s a good article for you. I've written a quick summary.
One of the charter responsibilities of DevOps (because it's a charter responsibility of ops) is measuring and monitoring applications once they're in production. That means both performance and availability. Which means a lot more than folks might initially think because generally spea...
In part 3 of our SDN series, I covered virtual versus physical infrastructure. This next segment will cover the three most commonly propounded benefits of SDN: efficiency, agility and security. Early, hyper-scale pioneers of SDN such as Google astounded the networking community with ...
For many MSPs, managing the outsourcing demands of their customers can result in a complicated relationship, but one that can be smoothed over by the MSP doing what’s right for them. Let me explain by example. I was in South Africa visiting a large MSP. They were using Entuity to m...
For some, SDN was about operational efficiency; about driving more stability and consistency out of the processes that push applications through the app deployment pipeline into production. For others, it was really about financial efficiency - the drive to lower capital expenditures. ...
There's Big Data, then there's really Big Data from the Internet of Things. IoT is evolving to include many data possibilities like new types of event, log and network data. The volumes are enormous, generating tens of billions of logs per day, which raise data challenges. Early IoT ...
For years, we’ve relied too heavily on individual network functions or simplistic cloud controllers. However, they are no longer enough for today’s modern cloud data center. Businesses need a comprehensive platform architecture in order to deliver a complete networking suite for IoT en...
In the consumer IoT, everything is new, and the IT world of bits and bytes holds sway. But industrial and commercial realms encompass operational technology (OT) that has been around for 25 or 50 years. This grittier, pre-IP, more hands-on world has much to gain from Industrial IoT (II...
SYS-CON Media announced today that Sematext launched a popular blog feed on DevOps Journal with over 6,000 story reads over the weekend. DevOps Journal is focused on this critical enterprise IT topic in the world of cloud computing. DevOps Journal brings valuable information to DevO...
There are numerous applications for big data in the education sector from admissions to monitoring cheating. Where’s Big Data’s next big splash going to be? We’ve already seen it make waves in the healthcare industry as it combats death. It’s taken athletics to the next level by moni...
For those deciding to embrace Software Defined Networking there are several obstacles to be overcome before deployment. Probably the hardest decision is which vendor to select. Given that the various SDN options are predominantly not interoperable, the decision as to which vendor to ...
SDN is a still simmering trend. It's not boiling over like cloud did in its early years but rather it's slowly, steadily continuing to move forward as more organizations evaluate, pilot and implement pockets of SDN within their organization. stage of sdn deployment 2015 But it's not ...
When the melting pot boils down to it, our network is its own culture, with recurring traffic patterns, similar end users, and equipment named after inside jokes only your company will understand. Just like living within your own culture, it's important to not only understand HOW patt...
It is possible to implement SDN solely using existing network infrastructure and to provide SDN overlay connectivity using tunneling technologies. That said, most people concede that some physical hardware will be needed to perform certain key network functions or at key locations wit...
SDN technologies are broadly split into two fundamentally different paradigms - "overlay" SDN and "underlay" SDN. With overlay SDN the SDN is implemented on top of an existing physical network. With underlay SDN, the fabric of the underlying network is reconfigured to provide the pat...
For me the mantra of achieving speed via automation tools is nothing new. In fact I was ‘automating’ Citrix Metaframe builds using windows scripting techniques back in 2004. The market though, has become awash with different automation products and it’s fair to say that many enterprise...
Imagine you are dropped off in the middle of a jungle, without any familiarity of what to eat, where to drink, or how to build a fire and shelter. Were you ready? Do you survive? In an environment that can, quite literally, eat you alive, it helps to be equipped with the right tools an...
In part 4 of our series on SDN, I discussed some of SDN's most commonly asserted benefits. Here I'll look at the drawbacks, the majority of which are organizational or financial and not technical. The most commonly cited reasons for actively not deploying SDN are: Staffing SDN r...
One of the best ways to get a raise is to demonstrate your value and commitment to your company and management. And one of the best ways to do that is by putting in the time and effort to obtain bona fide certifications in your chosen specialty. The difference in salary between a certi...
Surprise, surprise! The world just got a little faster. In other news, water is wet, grass is green, and you still didn’t win the lottery. According to the latest State of the Internet report, Akamai has discovered this “quickening” trend in their fourth quarter analysis of internet...
Early, hyper-scale pioneers of SDN such as Google astounded the networking community with the increased network utilization they achieved using SDN. The industry norm for WAN link utilization is between 30% and 50%, whereas, by deploying SDN, Google drove utilization up to 95% (withou...
Infonetics analyst Clifford Grossner recently released a SDN enterprise study which found that nearly 80 percent of medium and large size businesses plan to implement SDN technology in the data center by 2017. The survey of 153 businesses also revealed that 65 percent of respondents ar...
TAPs and NPBs are certainly on a collision course and their functionality and use cases are overlapping more and more. Traditionally TAPs were relatively unintelligent - providing pass-through monitoring points (possibly with very limited filtering), passing a copy of the data seen on...
Polymorphism is a concept central to object-oriented programming. The notion of polymorphism is used to extend the capabilities of a basic object, like a mammal, to specific implementations, like cats or dogs or honey badgers, even though they don't care about such technical distinctio...
Vicom Computer Services, Inc. was awarded an 11 year contract with the MTA. The MTA launched a request for proposal in September 2013 for a project encompassing and creating a fully redundant core data network across the three core data centers and upgrade user access to applications...
In cloud-based architectures, the situation is different and the network has become even more important. Let’s imagine a typical cloud-based architecture situation. You run a datacenter with a flexible number of allocated computing instances (for example, due to the pricing model and v...
