Management and monitoring in Software Defined Data Centers (SDDC) benefit from automation principles, programmability, API and policy-driven provisioning of application environments through self-service templates. These best practices help application owners to define, manage and monitor their own environments, while benefiting from the performance, security, business continuity and monitoring infrastructure from the IT teams. SDDC also changes the way IT designs and thinks about infrastructure – the goal is to adapt to demands of continuous delivery needs of application owners in a “cloudy” world.
When provisioning applications and network infrastructure in SDDC, particular attention is required when responses are slowing down, so visibility through proactive monitoring is critical to determine the root cause and why an application is not meeting its SLA requirements. Moreover, it is important to know these issues before they become a business disruption.
Not only is proactive monitoring and troubleshooting through actionable insights helpful in configuring the appropriate technical capability to address the issue at hand; this visibility into application performance is important in terms of cost saving – for example, to de-provision unused resources when not needed or to mitigate an attack in progress.
In many such environments, the Application Delivery Controllers (ADCs), sometimes also called load balancers, are at the intersection of the network and applications. ADCs act as sensors to changing user demands of the applications – for example, detecting increased user latency or a lack of available application resources, or reaching a throughput limit, or outage of a specific service or a security attack in progress.
In order to detect any application performance issues in real-time before your customers experience them, it is essential to have an end-to-end monitoring capability that provides actionable insights and alerts. The ADC can act upon this telemetry to trigger automation and orchestration systems to program the applications or the network elements as needed.
An important step in achieving operational visibility is end-to-end measurement. Next generation ADCs can provide a very cost effective continuous monitoring of quality of experience.
