There are a plethora of tactics used to test applications as they move to production. For example, as a developer I've created data and captured data for testing and - my favorite - ignored testing altogether. After all, it worked on my machine.
The reason there are so many tactics is there are so many ways in which real users - and thus real data - can expose all sorts of errors and defects in software. From logic flow interruption to corrupting databases to unintentionally writing over the end of a length limited string to wipe out some other piece of data in an adjacent memory location*, the possibilities of how real users will interact with and invariably mess up an application are virtually limitless.
Optimally (for the business, for the developer and even for the user) the best scenario is one in which real users and the data they input (sounds like that would be a good book, wouldn't it?) would be used to test new versions of applications.
In most cases, this is ultimately what happens when the application finally makes it into production because no matter how hard you try you're going to miss a corner case (or three). Even if you tested for weeks, once real data and users hit the application you're going to find problems.
The solution is to replicate real user data and interactions on pre-production versions of applications transparently. Turns out this is fairly easily accomplished - if you've got the right tools.
Application Proxy to the Rescue
Production application traffic replication can be easily accomplished using an application proxy and a bit of node.js. By deploying the proxy in front of the applications it can be directed (via node.js) to send incoming user requests to both the production and staging (or pre-production or test or qa or whatever you call the environment right before production. You do have an environment right before production, right?) applications.
The trick is, of course, that you only want one of the responses (the one from the production version) to return to the user. Which means you've got to catch the response from the staging version and discard it (or log it or whatever you want to do with it - except send it back to the user). A proxy by design manages this scenario quite well, with no disruption to the network.
Network-minded folks will instantly recognize this pattern as one implemented by spanning ports or mirroring traffic (or sessions) at higher layers of the network stack. It's a well-proven and tested pattern that enables developers and devops to really test out an application - from logic to data handling - using real user data and interactions.
F5 LineRate Proxy is able to easily implement this scenario. You can learn more about (and download a free version of) LineRate Proxy here.
* Hey, we used to play with pointers in my day, all the time. If you weren't careful you could do some really, uh, interesting things to an application.
In a world of ever-accelerating business cycles and fast-changing client expectations, the cloud increasingly serves as a growth engine and a path to new business models. Dynamic clouds enable businesses to continuously reinvent themselves, adapting their business processes, their service and software delivery and their operations to achieve speed-to-market and quick response to customer feedback. As the cloud evolves, the industry has multiple competing cloud technologies, offering on-premises and off-premises cloud platforms for both Infrastructure as a Service (IaaS) and Platform as a Servi...

DevOps is all about agility. However, you don't want to be on a high-speed bus to nowhere. The right DevOps approach controls velocity with a tight feedback loop that not only consists of operational data but also incorporates business context. With a business context in the decision making, the right business priorities are incorporated, which results in a higher value creation. In his session at DevOps Summit, Todd Rader, Solutions Architect at AppDynamics, discussed key monitoring techniques that facilitate higher value creation for your enterprise.

The move in recent years to cloud computing services and architectures has added significant pace to the application development and deployment environment. When enterprise IT can spin up large computing instances in just minutes, developers can also design and deploy in small time frames that were unimaginable a few years ago. The consequent move toward lean, agile, and fast development leads to the need for the development and operations sides to work very closely together. Thus, DevOps becomes essential for any ambitious enterprise today.

The cloud has transformed how we think about software quality. Instead of preventing failures, we must focus on automatic recovery from failure. In other words, resilience trumps traditional quality measures. Continuous delivery models further squeeze traditional notions of quality. Remember the venerable project management Iron Triangle? Among time, scope, and cost, you can only fix two or quality will suffer. Only in today's DevOps world, continuous testing, integration, and deployment upend the time metric, the DevOps cadence reinvents project scope, and cost metrics expand past software ...

Docker offers a new, lightweight approach to application portability. Applications are shipped using a common container format and managed with a high-level API. Their processes run within isolated namespaces that abstract the operating environment independently of the distribution, versions, network setup, and other details of this environment. This "containerization" has often been nicknamed "the new virtualization." But containers are more than lightweight virtual machines. Beyond their smaller footprint, shorter boot times, and higher consolidation factors, they also bring a lot of new fea...
