Microservices are a type of software architecture where large applications are made up of small, self-contained units working together through APIs that are not dependent on a specific language. Each service has a limited scope, concentrates on a specific task and is highly independent...
Providing a full-duplex communication channel over a single TCP connection, WebSocket is the most efficient protocol for real-time responses over the web. If you’re utilizing WebSocket technology, performance testing will boil down to simulating the bi-directional nature of your applic...
For Valentine's Day, here's a lighthearted look at the "relationship" between two complementary technologies: service virtualization and cloud dev/test labs. Hey, I know it's been a while since we started being "a thing." When we met, everyone said you were just mocking, and that I wa...
The battle over bimodal IT is heating up. Now that there’s a reasonably broad consensus that Gartner’s advice about bimodal IT is deeply flawed – consensus everywhere except perhaps at Gartner – various ideas are springing up to fill the void. The bimodal problem, of course, is well u...
As software organizations continue to invest in achieving Continuous Delivery (CD) of their applications, we see increased interest in microservices architectures, which–on the face of it–seem like a natural fit for enabling CD. In microservices (or its predecessor, “SOA”), the busines...
At the heart of the Cloud Native model is a microservices application architecture, and applying this to a telco SDN scenario offers enormous opportunity for product innovation and competitive advantage. For example in the ETSI NFV Ecosystem white paper they describe one of the prod...
In the Bimodal model we find two areas of IT - the traditional kind where the main concern is keeping the lights on and the IT focusing on agility and speed, where everything needs to be faster. Today companies are investing in new technologies and processes to emulate their most ag...
Web performance issues and advances have been gaining a stronger presence in the headlines as people are becoming more aware of its impact on virtually every business, and 2015 was no exception. We saw a myriad of major outages this year hit some of the biggest corporations, as well as...
Are you someone who knows that the number one rule in DevOps is “Don’t Panic”? Especially when it comes to making Continuous Delivery changes inside your organization? Are you someone that theorizes that if anyone implements real automation changes, the solution will instantly become a...
Welcome to the first top DevOps news roundup of 2016! At the end of last year, we saw some great predictions for 2016. While we’re excited to kick off the new year, this week’s top posts reminded us to take a second to slow down and really understand the current state of affairs. For ...
Test automation is arguably the most important innovation to the process of QA testing in software development. The ability to automate regression testing and other repetitive test cases can significantly reduce the overall production time for even the most complex solutions. As softwa...
I recently spotted a five-year-old blog post by Mike Gualtieri of Forrester, where he suggests firing your quality assurance (QA) team to improve your quality. He got the idea from a client who actually tried and succeeded with this counterintuitive move. The thinking goes that witho...
SDN / NFV may not be new with next gen telcos and data centers but by 2016 it is certainly going to be the new beast in DevOps space. It's a multi-million dollar virgin market, so it's not only those traditional OEMs are in the fray even the DB companies will be entering this new marke...
We started our Continuous Discussions (#c9d9) video podcast in late 2014 as a way for the DevOps community to connect with each others – sharing experiences, lessons learned and tips – to accelerate our mutual success.Each #c9d9 episode focuses on a different topic relating to your sof...
Shivon Zilis is an investor at Bloomberg Beta, a very interesting early stage venture capital fund. I knew I would like Bloomberg Beta when I saw how they do their website. It is smart and reflects very well on their leadership team: They decided to leverage GitHub for their site. Doin...
Is ITIL (Information Technology Infrastructure Library) still relevant in the digital world? The short answer is…yes. The longer answer is: it depends on your organization’s understanding and application of ITIL. In order to best answer the question it’s important to take a step bac...

Al Hilwa, program director of application development software at IDC, describes it this way: “Microservices is an architectural approach that draws on long, evolving experience in software engineering and system design, including the SOA efforts of the last two decades. The-challeng...
At the heart of the Cloud Native recipe is the shift to a ‘containerized microservices’ application architecture. This is a pretty fundamental shift in IT habits, embracing both the Docker-inspired container technology wave as well as a holistic transformation of how software is built...
According to the results of a new global study, commissioned by CA Technologies, 72% of organizations have implemented some aspect of DevOps but when the study took a closer look at the numbers, only 20% of DevOps users have put all the parts in place to reap the full benefits of DevOp...
Developers are often caught between a rock and a hard place. They aren’t allowed to employ the tricks of the trade that can squeeze more performance out of their code because the consequences – technical debt stemming from impaired maintainability - are generally considered even worse....
I have known Gartner for decades during my IBM and Oracle days. Even though I have observed how they invent new terms for stuff we already know (a bit annoying, but I guess that’s their business), they do a decent job in capturing key strategic trends. In a recent article, I saw ten s...
At year-end, we often consider where we’ve fallen short over the last twelve months – and how we can do better over the next twelve. For IT leaders, DevOps is likely to be a primary concern for 2016. As application awesomeness becomes more important to the business, IT must get great c...
In the Gartner white paper Taming the Digital Dragon, they define the Hybrid Cloud model as an enabling blueprint for digital transformation and leadership. They give it such an elaborate name because their definition goes far beyond the normal industry use of the term, a mix of on-pr...
Looking back at 2015, this past year saw significant changes in the software industry. Increasingly, software is more and more pervasive in nearly all aspects of our everyday lives, from business, government and education to shifts in the way we travel, parent, and monitor our health a...
Manufacturing has widely adopted standardized and automated processes to create designs, build them, and maintain them through their life cycle. However, many modern manufacturing systems go beyond mechanized workflows to introduce empowered workers, flexible collaboration, and rapid i...
Here at VictorOps, we rely heavily on Akka and during my time working with the environment/tool/language, I started seeing similarities between microservices and actors. Actors allow you to take pieces of your app, put them on their own servers and then enable them to communicate via H...
Ah, yes, the holiday season. A surprising dearth of snow, crass commercialism, yet another skirmish in the perennial ‘war on Christmas.’ And sure enough, the pinnacle of punditry: tech predictions for the New Year. At Intellyx, however, we’re adding a twist: in keeping with our long-s...
In a VentureBeat article the author describes ‘the future of enterprise tech‘, describing how pioneering organizations like Netflix are entirely embracing a Cloud paradigm for their business, moving away from the traditional approach of owning and operating your own data centre populat...
Proxies are one of the more interesting (in my no-doubt biased opinion) “devices” in the network. They’re the basis for caching, load balancing, app security, and even app acceleration services. They’re also a bridge between dev and ops and the network, being commonplace to all three g...
Sematext has combined the power of SPM and Logsene in a single pane of glass – a unified view into all the key bits of operational intelligence every DevOps engineer needs: server and application performance metrics, logs, events, anomalies, alerts, ChatOps integrations, etc. In other...

In today’s pharmaceutical supply chain, counterfeit activity is thriving. As pharma companies have expanded target markets and outsourced production over the last decade, the supply chain has become increasingly global, virtual, and vulnerable. Illicit activity has thrived, and patient...
This morning on #c9d9 we spoke with two industry veterans and published authors - James DeLuccia and Jonathan McAllister - on how to bake-in security and compliance into your DevOps processes, and how DevOps and automation can essentially help you pass your next audit.
The annual holiday shopping season, which started on Thanksgiving weekend and runs through the end of December, is undoubtedly the most crucial time of the year for many eCommerce websites, with sales from this period having a dramatic effect on the year-end bottom line. Web performan...
About six years ago, Netflix began the move from a monolithic to cloud-based microservices architecture, openly documenting the journey along the way. Netflix is one of the earliest adopters of microservices, a term that didn't even exist when Netflix began moving away from its monolit...
You may have heard about the pets vs. cattle discussion – a reference to the way application servers are deployed in the cloud native world. If an application server goes down it can simply be dropped from the mix and a new server added in its place. The practice so far has mostly been...
Using any programming framework to the fullest extent possible first requires an understanding of advanced software architecture concepts. While writing a little client-side JavaScript does not necessarily require as much consideration when designing a scalable software architecture, t...
