Programmability in the Network: Traffic Replication

Why waste time generating fake data to test when you can use the real deal?

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.

lr replication

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.

For organizations that have amassed large sums of software complexity, taking a microservices approach is the first step toward DevOps and continuous improvement / development. Integrating system-level analysis with microservices makes it easier to change and add functionality to applications at any time without the increase of risk. Before you start big transformation projects or a cloud migration, make sure these changes won’t take down your entire organization.

DevOps is often described as a combination of technology and culture. Without both, DevOps isn't complete. However, applying the culture to outdated technology is a recipe for disaster; as response times grow and connections between teams are delayed by technology, the culture will die. A Nutanix Enterprise Cloud has many benefits that provide the needed base for a true DevOps paradigm.

Providing the needed data for application development and testing is a huge headache for most organizations. The problems are often the same across companies - speed, quality, cost, and control. Provisioning data can take days or weeks, every time a refresh is required. Using dummy data leads to quality problems. Creating physical copies of large data sets and sending them to distributed teams of developers eats up expensive storage and bandwidth resources. And, all of these copies proliferating the organization can lead to inconsistent masking and exposure of sensitive data. But some organizations are adopting a new method of data management for DevOps that is delivering transformational business outcomes in faster time to market, lower costs, and great control. In his session at DevOps Summit, Brian Reagan, Managing Director of Blackthorne Consulting Group, an Actifio company, revi...

A Nutanix Enterprise Cloud has many benefits that provide the needed base for a true DevOps paradigm. In his Day 3 Keynote at 20th Cloud Expo, Chris Brown, a Solutions Marketing Manager at Nutanix, will explore the ways that Nutanix technologies empower teams to react faster than ever before and connect teams in ways that were either too complex or simply impossible with traditional infrastructures.
In recent years, containers have taken the world by storm. Companies of all sizes and industries have realized the massive benefits of containers, such as unprecedented mobility, higher hardware utilization, and increased flexibility and agility; however, many containers today are non-persistent. Containers without persistence miss out on many benefits, and in many cases simply pass the responsibility of persistence onto other infrastructure, adding additional complexity.

Keeping pace with advancements in software delivery processes and tooling is taxing even for the most proficient organizations. Point tools, platforms, open source and the increasing adoption of private and public cloud services requires strong engineering rigor - all in the face of developer demands to use the tools of choice. As Agile has settled in as a mainstream practice, now DevOps has emerged as the next wave to improve software delivery speed and output. To make DevOps work, organizations must focus on what is most relevant to deliver value, reduce IT complexity, create more repeatable agile-based processes and leverage increasingly secure and stable, cloud-based infrastructure platforms.

Virtualization over the past years has become a key strategy for IT to acquire multi-tenancy, increase utilization, develop elasticity and improve security. And virtual machines (VMs) are quickly becoming a main vehicle for developing and deploying applications. The introduction of containers seems to be bringing another and perhaps overlapped solution for achieving the same above-mentioned benefits. Are a container and a virtual machine fundamentally the same or different? And how? Is one technically superior to the other? What about performance and security? Does IT need either one, or both?

What if you could build a web application that could support true web-scale traffic without having to ever provision or manage a single server? Sounds magical, and it is! In his session at 20th Cloud Expo, Chris Munns, Senior Developer Advocate for Serverless Applications at Amazon Web Services, will show how to build a serverless website that scales automatically using services like AWS Lambda, Amazon API Gateway, and Amazon S3. We will review several frameworks that can help you build serverless applications, such as the AWS Serverless Application Model (AWS SAM), Chalice, and ClaudiaJS.
The essence of cloud computing is that all consumable IT resources are delivered as services. In his session at 15th Cloud Expo, Yung Chou, Technology Evangelist at Microsoft, demonstrated the concepts and implementations of two important cloud computing deliveries: Infrastructure as a Service (IaaS) and Platform as a Service (PaaS). He discussed from business and technical viewpoints what exactly they are, why we care, how they are different and in what ways, and the strategies for IT to transition into and take advantages of these emerging service models.
Culture is the most important ingredient of DevOps. The challenge for most organizations is defining and communicating a vision of beneficial DevOps culture for their organizations, and then facilitating the changes needed to achieve that. Often this comes down to an ability to provide true leadership. As a CIO, are your direct reports IT managers or are they IT leaders? The hard truth is that many IT managers have risen through the ranks based on their technical skills, not their leadership ability. Many are unable to effectively engage and inspire, creating forward momentum in the direction of desired change. Renowned for its approach to leadership and emphasis on their people, organizations increasingly look to our military for insight into these challenges.
