Application development trends significantly impact the design of data center networks. Today there are two trends driving a variety of transformation in the network: API dominance and micro-architectures. Combined with a tendency for network operations to protect its critical infrastructure from potentially disruptive change, these trends are driving toward an emerging "app network" tier in the data center that is software-defined.
This "app network" can be realized in one of two ways: through the deployment of application proxies, or via an application service fabric. The choice comes down to how integrated devops and network teams really are, and whether or not you have a service fabric available. If you do, it's a good solution as it affords the same flexibility as application proxies while removing platform-level management from devops shoulders. Only services need be configured, managed and deployed. An application proxy, too, is a good option and gives devops and developers complete control over the platform and the network-hosted domain services.
Today we're going to dive into the application proxy-based architecture.
APPLICATION PROXY ARCHITECTURE
Application proxies are highly programmable, scalable and perform with the alacrity expected of a "network" element.
Application proxies provide devops and developers with the mean to rapidly provision domain services specific to a micro-service or API. By decomposing traditional ADC-hosted services into domain specific, application proxy-hosted services, each service can be containerized and their deployment subsequently automated to ensure CPR (consistent, predictable and repeatable) results. Successful continuous delivery is the end goal. As noted earlier, this can be achieved via an application services fabric as well as dedicated application proxies.
This architectural model is more efficient in terms of resource consumption. Decomposing services ensures they scale independently. When services are code-level integrated into applications, the overall application footprint is much larger and requires more storage and more compute to scale. Decomposition reduces demand for storage and compute overall by only requiring expansion of a subset of services at any given time.
When the application proxy is highly programmable, devops and developers receive added benefits in the form of being able to codify services and treat as part of the code base rather than as separation configuration files. For example, specifying simple URI rewrite rules in some proxies requires changes to a configuration file. Using a programmable application proxy, such rules are coded and treated like artifacts; they can leverage existing build systems like Jenkins. They became part of the overall application rather than separate configuration files that must be merged, replaced, or otherwise managed. Using programmatic means to implement domain specific services affords devops more opportunity to seamlessly integrate with existing application deployment processes and increase its success rates.
The transformation of application architectures is driving data center networks toward a need for programmable domain services. These services must match service velocity and change the economy of scale as the number of applications needing services increases with each new application and application version. Not doing so means organizations will respond with discrete services that introduce operational risk and inability to consistently deploy new applications.
Both application proxies and application service fabrics meet these requirements, and both models are equally capable in offering a more seamless, less disconnected continuous delivery experience.

DevOps tends to focus on the relationship between Dev and Ops, putting an emphasis on the ops and application infrastructure. But that’s changing with microservices architectures. In her session at DevOps Summit, Lori MacVittie, Evangelist for F5 Networks, will focus on how microservices are changing the underlying architectures needed to scale, secure and deliver applications based on highly distributed (micro) services and why that means an expansion into “the network” for DevOps.

Adding public cloud resources to an existing application can be a daunting process. The tools that you currently use to manage the software and hardware outside the cloud aren’t always the best tools to efficiently grow into the cloud. All of the major configuration management tools have cloud orchestration plugins that can be leveraged, but there are also cloud-native tools that can dramatically improve the efficiency of managing your application lifecycle. In his session at 18th Cloud Expo, ...

We call it DevOps but much of the time there’s a lot more discussion about the needs and concerns of developers than there is about other groups. There’s a focus on improved and less isolated developer workflows. There are many discussions around collaboration, continuous integration and delivery, issue tracking, source code control, code review, IDEs, and xPaaS – and all the tools that enable those things. Changes in developer practices may come up – such as developers taking ownership of code ...

All organizations that did not originate this moment have a pre-existing culture as well as legacy technology and processes that can be more or less amenable to DevOps implementation. That organizational culture is influenced by the personalities and management styles of Executive Management, the wider culture in which the organization is situated, and the personalities of key team members at all levels of the organization. This culture and entrenched interests usually throw a wrench in the work...

Thanks to Docker, it becomes very easy to leverage containers to build, ship, and run any Linux application on any kind of infrastructure. Docker is particularly helpful for microservice architectures because their successful implementation relies on a fast, efficient deployment mechanism – which is precisely one of the features of Docker. Microservice architectures are therefore becoming more popular, and are increasingly seen as an interesting option even for smaller projects, instead of being...

As the race for the presidency heats up, IT leaders would do well to recall the famous catchphrase from Bill Clinton’s successful 1992 campaign against George H. W. Bush: “It’s the economy, stupid.” That catchphrase is important, because IT economics are important. Especially when it comes to cloud. Application performance management (APM) for the cloud may turn out to be as much about those economics as it is about customer experience.

When you focus on a journey from up-close, you look at your own technical and cultural history and how you changed it for the benefit of the customer. This was our starting point: too many integration issues, 13 SWP days and very long cycles. It was evident that in this fast-paced industry we could no longer afford this reality. We needed something that would take us beyond reducing the development lifecycles, CI and Agile methodologies. We made a fundamental difference, even changed our culture...
