Imagine that you are designing the 2017 Ford Mustang. Like all gas-powered vehicles, each one needs an exhaust muffler. Ford has already vetted and narrowed in on a preferred provider of mufflers. But imagine what would happen if the designers and factory line workers could pick from a...
Microservices are all the rage right now — and the industry is still learning, experimenting, and developing patterns, for successfully designing, deploying and managing Microservices in the real world. Are you considering jumping on the Microservices-wagon? Do Microservices make sense...
On a recent road trip I was reminded about the importance of DevOps feedback loops and application supportability. I enjoy driving into the Australian outback. This probably explains why I prefer to take the back roads. On my last trip I did just that; forgoing the fast highway for a ...
A typical software testing team might have a business expert, a toolsmith, a few technical investigators, and perhaps a manager. A savvy manager knows one of the investigators is interested in mobile, another in APIs, and tries to ‘steer' the work toward the right person. This brings ...
If we look at slow, traditional IT and jump to the conclusion that just because we found its issues intractable before, that necessarily means we will again, then it’s time for a rethink. As a matter of fact, the world of IT has changed over the last ten years or so. We’ve been experi...
The (re?)emergence of Microservices was especially prominent in this week’s news. What are they good for? do they make sense for your application? should you take the plunge? and what do Microservices mean for your DevOps and Continuous Delivery efforts? Continue reading for more on M...
How is your DevOps transformation coming along? How do you measure Agility? Reliability? Efficiency? Quality? Success?! How do you optimize your processes? This morning on #c9d9 we talked about some of the metrics that matter for the different stakeholders throughout the software deliv...
In a previous article, I demonstrated how to effectively and efficiently install the Dynatrace Application Monitoring solution using Ansible. In this post, I am going to explain how to achieve the same results using Chef with our official dynatrace cookbook available on GitHub and on t...
For microservices to work in an organization, there must be a business initiative attached to it. Questions arise among IT professionals on whether microservices are suited only for giant Web applications like Google and Facebook. However, scale is only one of the business benefits of ...
I remember back in 2003 when I had a meeting with the then CTO of Amazon for a couple of hours. He was narrating his vision of SOA (Service Oriented Architecture), where individual business or programming functions (called services) can be stacked up in libraries and get invoked as and...
Enterprises are finally realizing that digital transformation must be end-to-end if they want to remain competitive in today’s software-driven, customer-focused world – but virtually every large organization has a massive boat anchor dragging them down – slow IT. Legacy technology woe...
It’s easy to understand the confusion that is caused when the terms Agile and DevOps start getting tossed around. Buzzword bingo, here we come. But these two terms are more than just marketing speak – they’re technical movements born out of the desire to deliver better software, collab...
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...
Explore the 10 most popular continuous testing resources of 2015, including Forrester and Gartner research, interviews, infographics, an ebook, and more. With today's DevOps and "Continuous Everything" initiatives, teams need the ability to assess the risks associated with a release ...
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...
