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...
Unless you have been living under a rock the last year, you have probably heard about Docker. Docker describes itself as an open platform for distributed applications for developers and sysadmins. That sounds great, but why does it matter? Wait, virtualization isn’t new!? Virtual...
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...
Regardless if you’ve migrated multiple applications or this is your first migration to a public Infrastructure-as-a-Service (IaaS) you will want to run a small proof-of-concept to make sure that the basic elements of data flow operate as expected and your components will run in the Iaa...
Isn’t it great to treat your girlfriend by cooking her favorite omelet every morning? In theory, sure, but in reality, chances are most of the time you end up with darn scrambled eggs instead. Let’s face it: you’re a great boyfriend but a terrible cook. Believe it or not, this is quite...
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...
Can we shift the conversation from talking about DevOps to sharing lessons learned about trying to implement DevOps? Over the past several months, I have had numerous conversations with a variety of Fortune 500 companies about how to embrace DevOps. Most enterprises understand why DevO...
In my hunt for the mysterious DevOps practice, I’ve been let down. DevOps are hard to find. When you find them, they do not exactly do what you think they should do. Some DevOps teams only execute on automation for dev; while others are operations folks with a new name; and still other...
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...
This is part of the ever-expanding "Microservices and PaaS" blog series covering the rapidly evolving use of microservices in modern cloud software projects. Parts I and II introduced microservices concepts and discussed patterns and practices being spearheaded by microservices pioneer...
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...
I just recently wrote a blog about BOTs causing unwanted traffic on our servers. Right after I wrote this blog I was notified about yet another “interesting” and unusual load behavior on our download page which is used by customers to download latest product versions and updates. If y...
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...
To say that Operations and DevOps will have a new set of challenges in the coming year is a bit redundant, as their entire job is based on solving problems and facing challenges. However the current and future landscape of tools, technologies, and processes is changing dramatically....
Target. Home Depot. Community Health Systems. Nieman Marcus. Their names have been all in the news over the past year, though probably not in a way they would like. All have had very public data breaches affecting anywhere from 350,000 (Nieman Marcus) to 4.5 million (Community Health S...
As co-founder of Logentries I am often asked - "Why Logs?" And I have to admit, upon first impression, ‘log management and analytics' does not seem like the sexiest space :). However at Logentries we are here to redefine that space, to provide a solution to access, manage and understa...
Qubell is staking out its territory in DevOps, with a collection of components, connectors and starter kits that are “self-deployable composite applications and blueprints that showcase a complete technical solution to a common business problem,” in the words of the company. Starter ki...
For a concept that is barely a couple years old, DevOps is red hot. No conversation about software development is considered complete without the mention of this new buzz word. But the growth in its popularity has also given rise to several misconceptions. Misconceptions that, if...
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...
One of the most common questions we get asked by customers is: “What’s the best way to log my data?” My answer is always: "log using JSON format wherever possible.” The next question we often get asked – (but not as much)… Yeah JSON, …Hmmm, what is JSON again? So JSON is: S...
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...
Every day and every second, the system administrator gets tones of information on the network operation, network devices’ operation, and messages from users; he sets dozens of challenges, which must help to avoid the existing and possible problems in the future. Often, it is rather dif...
Log analysis is a simple and cool way to add oversight to your orchestration environments. While scripting your infrastructure is a powerful tool, using it alone is a quick-hit device. But wait, there is more! You don’t even have to create the scripts manually; there are tools ou...
We're working hard in the Logentries towers to integrate our continuous delivery tools, so we can identify and track issues as easily as possible. This saves us time that we can spend on important things like adding new features (or playing pool!). We use a lot of tools to manage our...
“DevOps” is one of those buzzwords that means everything and nothing at the same time. It is like the words “cloud,” “architecture,” and “Internet of Things”—terms so vague they lead to endless debates between IT people. DevOps seems to take this verbal sparring to a new level. On top ...
Docker for Smarties (e.g. non-dummies) from VMworld 2014 By Greg Schulz Docker for Smarties (e.g. non-dummies) from VMworld 2014 In this Industry Trends Perspectives video pod cast episode (On YouTube) I had a chance to visit with Nathan LeClaire of docker.com at the rece...
Goodness there is a lot of talk about cloud computing. This ‘talk and chatter’ is part of the problem, i.e., we look at it, we prod it and we might even test it out – but do we get down to practical implementation, deployment and (if you happen to be a fan of the term) actual cloud ‘ro...
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...
Are you developing or hosting PHP applications? Are you doing performance sanity checks along your delivery pipeline? No? Not Yet? Then start with a quick check. It only takes 15 minutes and it really pays off. As a developer you can improve your code, and as somebody responsible for y...
I would say that only one out of a million exceptions thrown in an application actually makes it to a log file – unless you run your application in verbose logging mode – Do you agree? No? Here is why I think that is: because most exceptions are handled by your code or by the framework...
In my role as technology evangelist I spend a lot of time helping organizations, big and small, make their IT systems better, faster and more resilient to faults in order to support their business operations and objectives. I always find it frustrating to “argue” with our competitors a...
How often do you deploy new software? Once a month, once a week or every hour? The more often you deploy the smaller your changes will be. That’s good! Why? Because smaller changes tend to be less risky since it’s easier to keep track of what has really changed. For developers, it’s ce...
Skytap recently announced the availability of a Docker template in the Skytap Cloud Public Template Library. Docker is an open platform for developers and sysadmins to build, ship, and run distributed applications. This new template allows you to easily experiment with or deploy Docke...
Silver shows that predictions in areas such as economics have been less successful, e.g. he examines why many economists missed the recession, and why supposedly expert forecasters get election predictions wrong so often. For example, before the recession of 2008, the assumption was ma...
We (as in the industry at large) don't talk enough about applying architectural best practices with respect to emerging API and software-defined models of networking. But we should. That's because as we continue down the path that continues to software-define the network, using APIs an...
You can then easily piece together full transaction traces by ordering all method calls by sequence number. Further analysis can be applied to this information for a number of purposes. For example, by analysing the transactions, developers can easily construct design diagrams that can...
As a lifelong word junkie, I can honestly say that I’ve never seen more debate, argument, and failure to reach an agreed upon definition of a word than we’re seeing over the word “DevOps.” And while it can be frustrating to find a definition that works for you, and not be swayed by the...
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...
