#SDN #DevOps Stateful is not stateless. And vice-versa.

 

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...

This past March, Oracle released their most anticipated version in almost decade, Java 8. The latest version had a growing buzz since it had been announced, and companies of all sizes were eager to upgrade. Our partner, Typesafe conducted a Java 8 adoption survey of 2,800 developers...

We had three quick questions for Mike Kail, and he had three quick answers. Mike is SVP of Infrastructure at Yahoo!, and formerly VP of IT Operations at Netflix. He'll be speaking at @DevOpsSummit about his experiences in integrating DevOps on a big scale in big-scale projects. ...
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...
So what is Laravel? Laravel is a relatively new MVC web framework for PHP that was released in 2012. It’s also the most popular PHP project on Github at the time of this post. Like many web frameworks, Laravel boasts an easy learning-curve to get an app up and running. This was cert...
Many businesses are closely scrutinizing the concept of Continuous Delivery and, in most cases, competitive pressure is the driver. CD allows you to deploy applications without having to write endless scripts, provisioning test environments on-demand, and creating delivery pipelines so...
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...
DevOps Journal: Cloud, Big Data, and the IoT all carry disruption within enterprise IT. The same goes with DevOps. Which of these is the major disruptor, in your opinion? Andi Mann: It may well be cloud, because it fundamentally enables all the rest. Cloud scale is why we are now co...
Despite the fact that majority of developers firmly believe that “it worked on my laptop” is a poor excuse for production failures, most don’t truly understand why it is virtually impossible to make your development environment representative of production. When asked, the primary rea...
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 ...
This story came in from Joseph – one of our fellow dynaTrace users and a performance engineer at a large fleet management service company. Their fleet management software runs on .NET, is developed in-house, is load tested with JMeter and monitored in Production with dynaTrace. A usage...

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...
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...
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...
Have you ever deployed a change to production and thought “All went well – Systems are operating as expected!” but then you had to deal with users complaining that they keep running into errors? We recently moved some of our systems between two of our data centers – even moving some c...
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...
"We see cloud and DevOps as two sides of the same coin. Often times operation folks have been focused on cloud computing as a way to deliver infrastructure in an agile fashion, but to make use of that infrastructure you need DevOps where you’re doing some of the process reengineering t...
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...
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...
The Application Economy is here and there’s no turning back. Applications have become the primary face of business, and they’re easier to use than ever before. Your customers are far more likely to experience your brand and interact with your enterprise through a software app than a li...
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...
Inarguably, the pressure is on "the network" to get in gear, so to speak, and address how fast its services can be up and running. Software-defined architectures like cloud and SDN have arisen in response to this pressure, attempting to provide the means by which critical network servi...
​This technical, but easy-reading story will likely become required reading for everyone here at Skytap. The Phoenix Project: A Novel About IT, DevOps and Helping Your Business Win (Gene Kim...
This post is the first in a multi-part series of posts on the many options for collecting and forwarding log data from different platforms and the pros and cons of each. In this first post we will focus on Syslog, and will provide background on the protocol. Syslog has been around for...
One funny thing about DevOps is that it is often touted that constant, on-the-fly changes are the way of the future in operations, and DevOps enables those changes. While this sounds really good, and some organizations are actually doing this type of DevOps, I think it is time that, fo...
A funny thing has happened in the technology world, the hype cycle has become far more than a cycle that you watch and smile at. It has become a sales frenzy, while people try to make a name and/or sell you stuff before the idea or product category has even solidified. You can see it a...
The old monolithic style of building enterprise applications just isn't cutting it any more. It results in applications and teams both that are complex, inefficient, and inflexible, with considerable communication overhead and long change cycles. Microservices architectures, while the...
Picking up where we last left off, Yung Chou and Keith Mayer continue our Accelerate DevOps with the Cloud series as they welcome Andrew Weiss from Microsoft Consulting Services as they show us how we can manage Docker containers using PowerShell DSC...(Sep. 1, 2014 11:00 PM EDT  Reads: 3,460
