Application Delivery Controllers understand applications and optimize server performance - offloading compute-intensive tasks that prevent servers from quickly delivering applications. Learn how ADCs have taken over where load balancers left off.
With increasing demands being made on enterprise IT
departments to keep up with the accelerating pace of business,
infrastructure has to enable more dynamic, eficient application
and IT service delivery. Unfortunately, more ofen than not, IT
provisioning can be a bottleneck. Traditional means are ofen
ineficient. When developers plan their projects and estimate the
server, networking, and storage resources they need, they ofen
overestimate and pad their requests to ensure what actually
gets provisioned is adequate. The formal request comes via an IT
ticket, and then the waiting begins. Days, possibly weeks go by
before they get the resources they need, and all the while they’re
unable to iterate on and evolve core business oferings.
The advent of cloud computing and software-defined data center architectures for modern application delivery has made networking more sensitive than ever before. Applications in the digital age require networks that can expand and contract dynamically based on consumer demand. Enterprises are implementing software-defined networking (SDN) to deliver the automation required by these new environments, but the dynamic nature of SDN makes network management and monitoring fundamentally more challenging.
Network infrastructure teams need monitoring tools that can provide visibility into these new and constantly changing networks. This white paper explores the importance of SDN monitoring and examines a leading example of a solution, CA Performance Management with CA Virtual Network Assurance integration.

Organizations are looking to SDN to improve network agility by incorporating network automation in cloud computing platforms. So far the focus of SDN has been on L2-L3 switching and routing services. However applications don’t just need network connections. They also need L4-L7 network services.
To meet the growing challenges of a competitive world economy, a digital transformation is taking place in the enterprise. Organizations realize that to be competitive they need to be more agile. They need to reach their customers wherever they are, and they need to be able to scale their applications to meet customer demands.
To meet these challenges, organizations are deploying new microservice applications that are changing the application delivery environment. These applications are agile, configured to enable new features to be added without disrupting applications in production, and designed to automatically instantiate instances in response to increasing user demand. In short, microservices are drastically changing the way that applications are deployed and managed. This introduces a high level of complexity to network infrastructures because traditional applications are not going away. Applications will continue to be designed for both microservices and traditional 3-tier imple
The world of IT is undergoing a digital transformation. Applications are growing fast, and so are the users consuming them. These applications are everywhere—in the datacenter, on virtual and/or microservices platforms, in the cloud, and as SaaS. More and more apps are now being moved out of datacenters to a cloud-based infrastructure.
In order for an optimized and secure delivery of these applications, IT needs specific network appliances called Application Delivery Controllers (ADCs). These ADCs come in hardware, virtual, and containerized form factors, and are sized by Network Administrators based on the current and future usage of applications. The challenge with this is that it’s hard to foresee sizing or scalability requirements for these ADCs since users are constantly increasing, and applications are consistently evolving, as well as moving out of datacenters.
Complicating matters, most ADCs are fixed-capacity network appliances that provide zero or minimum expansion capability

Let’s face it, users are impatient. They demand a blazingly fast experience and accept no substitutes. While the effects of poor performance are obvious, it makes one wonder about the relationship between client latency and the “perception of speed”. After all, the user can trigger many state change events (page load, submit a form, interact with a visualization, etc.) and all these events have an associated latency to the client. However, are certain types of latency more noticeable to the user then others?

Applications are the life of any enterprise and key enablers of workforce productivity and business agility. But, the application landscape is changing rapidly - the number and type of applications is increasing, the move to cloud and SaaS for application delivery is growing, bandwidth costs are decreasing and the reliability of the Internet has improved. Inevitably, there are also changes in network and infrastructure topologies.
Cloud computing and the "bring your own device" (BYOD) trend will impact the design of future datacenters and their supporting networks. To attain the kind of business agility that companies now demand, network infrastructure needs to provide the flexibility required by cloud application workloads and the changing traffic patterns fostered by BYOD. To make networks more agile, new approaches to network implementation need to be enabled. As these trends continue, application delivery controllers (ADCs) will be critical elements in the new network infrastructure. This Technology Spotlight examines these trends and the role that F5 Networks' integrated scalable platform plays in this strategic market.
Information technology is at a crucial turning point. Enterprise IT departments are under constant pressure to meet user and application demands, aware that cloud deployments offer an easier and faster alternative but often pinned down by legacy deployment models. The problem stems from the inability of those legacy models to adapt to meet expectations for rapid provisioning, continuous delivery, and consistent performance across multiple environments. Read this whitepaper to learn more about the evolution of application delivery and the services your enterprise can utilize to successfully manage the increased pressure on network and application infrastructure.

As enterprise computing has evolved, businesses have been shifting to a “hybrid enterprise” where core applications and data can be located in private data centers and public clouds. The growth of hybrid cloud deployments accelerated the transition to hybrid wide-area networks (WANs). Private networks, such as MPLS, are being joined by Internet connections that offer a choice in delivery
channels—costly, but predictable, networks for mission-critical loads and cheaper public networks for bulk loads such as data backups.
Building out a dedicated infrastructure with the agility, scalability, and effciency of a public cloud—while enjoying increased levels of control and security—can help enterprises boost agility and improve operational ef?ciency. However, while most private cloud networking services provide basic load balancing functionality, they lack important application delivery features, putting the performance, availability, and security of applications at risk.
As private clouds increasingly host mission-critical production applications, advanced application delivery services for layers 4 through 7 are becoming essential. End-to-end integration, orchestration, and automation of the needed application delivery networking and security services are also critical to improve application time-to-market and operational ef?ciency.
