In the last decade, how we consume applications in enterprise environments has changed drastically. Our mobile devices and tablets have taken the place of traditional workstations and desktops, and many enterprises already are virtualizing bare metal servers and merging them into centralized data centers.
With these changes, among others, no longer is the enterprise data center the hub for application delivery. Instead, it has become just another part of the application delivery chain and the cloud is now the hub. Because of these advances, network monitoring technologies have adapted as well. Today, the approaches of the 2000s have fallen by the wayside as more complex and diverse environments need a new method to handle network monitoring.
In a new white paper from ThousandEyes, it’s argued that legacy network monitoring, with its multiple hardware boxes and difficult provisioning, worked for static clients, but in today’s very mobile world, having the data center as the hub is not the most efficient method. Instead, “The Evolution of Network Monitoring from Data Center to Cloud” suggests the cloud should work as the monitoring hub to solve today’s network challenges. Past strategies worked in silos and lacked correlation between data sets, resulting in difficult network troubleshooting.
This evolution of network monitoring means what we did 10 years ago isn’t enough for the networks of today. With longer and more complex network paths and clients that can be anywhere, network fault isolation for current enterprise environments needs visibility beyond just the data center. The white paper argues this can only be achieved by using different types of instrumentation, including instrumentation of client devices, corporate data center, and the Internet. Today, networking monitoring solutions must be application-aware and capable of singling out underlying problems that impede the user experience. Older solutions lacked this capability, and only offered a glance into the network layer or over individual devices.
As software-defined networking (SDN) and network functions virtualization (NFV) continue to evolve our networks, it’s important to figure out which methods of monitoring are best able to meet the changing needs. The white paper looks to the past to figure out what is needed today, and offers insight on how monitoring in the cloud can give users data collection, application metrics, data sharing, user interface, management, local environment discovery, and software updates – all advantages that benefit the modern enterprise network.
