A Better Way to Deploy Applications in Today’s Data Centers (Part 2)

As I started discussing in my last post on the topic, a vADC per aApplication and application shaping tools provides the best solution for ADC deployments. This approach guarantees the applications SLA, and provides agile, scalable, cost effective solution with an application-centric approach. A vADC per Application plus the shaping tools enhance the core values of the ADC and provides a better solution.

With a vADC per App, we can guarantee the applications SLA. Resources are reserved and guaranteed per vADC, and applications don’t compete over shared resources, which results in predictable performance of each application. This enables us to scale application resources without impacting other applications.

For example, take an online store. During the upcoming holiday season, the store expects peak traffic levels. With this knowledge, we can increase the resources of the vADC and guarantee an excellent quality of experience for users. The proper design of this solution guarantees all applications SLA.

The application automation tool accelerates application rollout with configuration templates and wizards for popular mission-critical applications. An example of this is when we want to deploy a new application, such as SharePoint.

First, we select the SharePoint template from a list of available templates. Then, using specific management screens, we enter all the relevant information for the SharePoint application, such as the application server’s addresses. The template already contains the application delivery services that are unique for SharePoint, such as specific health checks and other parameters. Once we’ve completed entering the information, a new vADC is provisioned on the correct device. The result is a faster application rollout, optimized application delivery and the new added application does not affect the other applications.

The application automation tool will also help with the day-to-day operations and central management of all applications and application centric reporting screens. It provides all of the reporting and the configuration of the application from a set of screens that shows only the application relevant information. This results in reduced operational costs and increased staff efficiency, a simplified ADC administration delegation, and the ADC administrator’s work becomes less tactical and more strategic.

A vADC instance per application also simplifies the operations with a smaller and simpler configuration file per vADC, which accelerates the troubleshooting. In addition, each vADC should run its own OS.

An example of this is a new acceleration feature for SharePoint that requires an ADC software upgrade. Instead of scheduling a maintenance window for the entire ADC, only upgrading the vADC for the SharePoint application is necessary. The rest of the applications continue to work without interruption and they don’t need to be tested with the new ADC software. The result is minimum downtime and increased efficiency.

The above solution recommendation is a future-proof one with an on-demand scalability strategy. All of your future ADC needs are met with the same hardware. On demand technology reduces cost and increases agility. A vADC per app and an integrated application automation tool can provide the best solution for ADC deployments. This ADC solution guarantees all the applications SLA while providing an agile, scalable and cost-effective solution with an application-centric approach.
