A Man in the Middle attack, or MITM, is a situation wherein a malicious entity can read/write data that is being transmitted between two or more systems (in most cases, between you and the website that you are surfing). MITMs are common in China, thanks to the “Great Cannon.” The “Gre...
Try to remember something that happened on your last vacation. How long did it take you to recall? Now, try to remember it again. You were probably able to recall it faster the second time— but, why? This is because as soon as you recalled the event the first time, your brain saved the...
The goal of Continuous Testing is to shift testing left to find defects earlier and release software faster. This can be achieved by integrating a set of open source functional and performance testing tools in the early stages of your software delivery lifecycle. There is one process ...

Are you tired of slipping deadlines and missing commitments? Do you feel like the consistency of Software Testing is out of your control? Here is how to improve the predictability of software testing across multiple teams and projects. The foundation of enterprise software testing pre...
Developing code, without considering either the current or future needs of the end user, can cause frustration and result in customer churn, which ultimately means lower revenues. In this blog, I'd like to describe something simple I came across that demonstrates how to avoid these pit...
After 15+ years of software development, I still use the words error and exception interchangeably. But is there a difference between exceptions and errors? I think it is best to make the distinction with some examples of errors vs exceptions. Let's use this example of a dishwasher....
Exceptions are a type of error that occurs during the execution of an application. Errors are typically problems that are not expected. Whereas, exceptions are expected to happen within application code for various reasons. Applications use exception handling logic to explicitly handl...
There are some big red flags that signify your DevOps department needs an overhaul. Your deployment process seems to take forever. It only work from a few developers’ computers. It’s different for each server you deploy to. Sound familiar? Luckily the warning signs of a DevOps depar...
Getting started is often the largest hurdle with any major project. Research, theory, and discussions are like the 30ft boat taking you and your team from the shore to a seemingly random point in the ocean where you will strap on your diving suit and plunge backward into the depths we’...
If DevOps continues on the same trajectory into 2017 as it has been on for the past few years, specialized Ops teams could quickly become redundant. Instead, DevOps for digital companies will evolve to require only developers who nurture their own code into production. So how do establ...
By now, every company in the world is on the lookout for the digital disruption that will threaten their existence. In study after study, executives believe that technology has either already disrupted their industry, is in the process of disrupting it or will disrupt it in the near fu...
Bimodal IT was initially defined by Gartner as, "The practice of managing two separate but coherent styles of work: one focused on predictability, the other on exploration." Of course this needs a little unpacking, but in essence Bimodal IT refers to the notion of two distinct areas...
One hour before March Madness is about to begin, the CBS Sports app crashes. Per Twitter, college basketball fans across the country are freaking out, trying to get their last minute bracket changes completed before the first game begins. Millions of fans around the world are expected...
To make sure we’re on the same page, let’s start by defining what we mean by a silo. “They are nothing more than barriers… between departments… causing people… to work against each other.” -Patrick Lencioni in 'Silos, Politics, and Turf Wars' Thanks to the work of Lencioni we ha...
Ask any IT person from the financial sector about SOX requirements and they’ll probably use some colorful language about how much time and money it sucks away. According to the 2016 Sarbanes-Oxley compliance survey by global consultant Protiviti, the average annual internal cost of SOX...
Few questions in software development are more divisive or tribal than choice of programming language. Software developers often identify strongly with their tools of choice, freely mixing objective facts with subjective preference. The last decade, however, has seen an explosion both...
If technical debt were like monetary debt, it would be hard to keep track of it unless you checked in manually. The only way many people find out their checking account is running out of funds is by logging in and checking the balance — or, worse, having a check bounce or a debit card ...
Functional monitoring is the process of looking at the functionality offered by a single application or by a distributed system. It aims at the process of assessing the availability and functionality of the use cases of the system. It checks that the system is capable of giving desired...

So you've decided to take the infrastructure as a service (IaaS) approach to cloud migration. That's great-you're on your way to realizing the cost savings and flexibility of cloud computing. But the decisions don't stop when you choose between SaaS, PaaS, and IaaS. Choosing your pu...
Smart devices require smart monitoring. That’s not a platitude. It’s an imperative. In fact, the smarter the device, the smarter you need to be about monitoring it. As headlines have shown, unmonitored, unprotected smart devices may be a disaster (or a DDoS attack) just waiting to hap...
Thanks to the DevOps movement, we now understand why software delivery chains that consist of a series of silos are bad. They complicate communication between different teams, leading to delivery delays, backtracking, and bugs. When it comes to incident management, there is another ty...
How often is an environment unavailable due to factors within your project’s control? How often is an environment unavailable due to external factors? Are the software and hardware in an environment up to date with the target Production systems? How often do you have to resort to manua...
DevOps is being widely accepted (if not fully adopted) as essential in enterprise IT. But as Enterprise DevOps gains maturity, expands scope, and increases velocity, the need for data-driven decisions across teams becomes more acute. DevOps teams in any modern business must wrangle the...
