Logging in a Software Defined Network

Background This blog will give an overview of Software Defined Networks (SDN), present some suggestions for logging in an SDN and finally present an overview of some research work we are doing on SDN logging. If we consider a Software Defined Network (SDN) paradigm is a racetrack, SDN controllers are race cars. Networking vendors especially those in the telecommunication area such as Deutsche Telecom, Orange, Vodafone use their own SDN controllers to manage the orchestration of their own equi

Habits that Pay Off for Programmers

I would like to clarify something immediately with this post.  Its title does not contain the number 7, nor does it talk about effectiveness.  That was intentional.  I have no interest in trying to piggy-back on Stephen Covey’s book title to earn clicks, which would make this post a dime a dozen. In fact, agoogle search of “good habits for programmers” []yields just such an appropriation, and it also yields exactly the sorts of articles and

Legacy apps in the data center, today's apps in the cloud

Have you found that your organization is developing new applications that are cloud-based, but unable to move away from some established legacy systems? You aren’t alone. This legacy/cloud hybrid environment is far more common than you would expect. And when you look at the history behind these apps it does make sense. Any organization that has been around for more than a few years probably has some investment in at least one legacy application. Organizations that have been around longer may h

Network Administrator’s Guide to Surviving an Audit: Preparation

Sooner or later, your organization will likely be the subject of an IT audit. But as ominous as that sounds, it doesn’t have to be something to dread. If you’re a network administrator, you’ll have a specific role in an audit. Since audits are rarely small projects, you’ll likely be working with others throughout the process. The best way to fulfill your specific role well is to be prepared for an audit before it happens. Simply put, an audit is an examination to determine if controls are suff

Log Analysis for System Troubleshooting

Systems of all kinds create log data constantly and voluminously. In searching out the most compelling reasons to dig into and analyze such data, we compiled a list of seven reasons that usually drive such activity. In this blog post we tackle the first of those 7, which include: 1. System troubleshooting 2. Security incident response 3. Security troubleshooting 4. Performance troubleshooting 5. Understanding user behavior or activities 6. Compliance with security policies 7. Complianc

Logging for Fun: Things You'd Never Thought to Log

I work as a consultant in the software industry.  This work affords me the opportunity to see and interact with many different teams and thus to observe prevailing trends.  Among these teams, the attitude toward logging tends to be one of resigned diligence. That is, many developers view application logging the way they view flossing their teeth: a necessary, dull maintenance activity that will pay dividends later.  Today, however, I’d like to encourage readers to consider a different side of

Roots and Culture: Logging and the Telephone Bill

Telephone systems were the Internet before there was an Internet. Think about it. By 1920 millions of people were exchanging data on a worldwide network using a device that connected on demand. Sounds like the Internet to me. But unlike the current day Internet, the telephone system cost money to use. Alexander Graham Bell’s investors wanted it that way. That’s why they gave him the money. Thus, people who used the telephone system had to pay for it. So going as far back as 1877, every mont

5 Rules of Pair Programming Etiquette

I like Pair Programming []. I’ve been doing it episodically for about 10 years. Whenever I’ve pair programmed, at the end of a session, I’ve always walked away a better developer than when I started. However, the practice can be expensive when the pair doing the programming are not efficient. When a lot of friction exists between the two coders involved, costs can exceed double that of a single programmer trying to hash things out on his or her ow

3 Predictions for Development in the Age of Serverless Computing

Probably the biggest change that has happened in my lifetime of programming is the transformation from  creating code that is meant to run on known, tangible hardware to making code that runs on the Cloud. We’ve gone from server based computing to the serverless environment. The transformation has brought us the practice of DevOps. Also, the transformation has forced us to rethink the whole way design our code. Increasingly modern programming is about stitching together cloud based resources t

Java 8 - Lazy argument evaluation

Overview “I will always choose a lazy person to do a difficult job. Because he will find an easy way to do it” – Bill Gates Lazy evaluation is an evaluation strategy [] which delays the evaluation of an expression until its value is needed. The opposite of this is eager evaluation, where an expression is evaluated as soon as it is bound to a variable.[wikipedia []] Like most imperative programming l
