multicloud campus.pngAn Enterprise Migration: the Multicloud World

The migration to multicloud forces enterprise campus and branch networks to evolve, creating new opportunities and challenges. Whether for their large campus or smaller branch offices, customers expect an always-on, secure network, and they expect it at a fraction of their current cost. Shrinking IT budgets prevent businesses from affording large IT organizations just to keep the network running. This coupled with the increase in security threats compounds the challenge.


Fortunately, the infrastructure and technologies developed for cloud data centers are finding their way into campus networks. Automation technologies, elastic scaling of network infrastructure and pervasive security throughout the network are just some of these capabilities quickly becoming mandatory in the campus. If a network can auto-detect faults and mitigate security threats in real-time without costly intervention from the network administrator, the true benefits of a self-driving network can be realized.


Juniper’s Self-Driving NetworkTM for the Campus

At Juniper Networks we take pride in developing networks that self-manage and take us towards the Self-Driving NetworkTM vision. We believe that the enterprise campus is key to enabling a true multicloud experience for users. Hence, it must provide secure access for Internet connected devices. Security and simplicity must be designed in the infrastructure and no longer just an afterthought. This is a prerequisite for a system that auto-detects faults, assesses security threats and anomalies in real time, and self-remediates to avoid any impact to service or performance.


The Four Essential Network Solutions

As you design your modern enterprise network, consider the following four essential solutions from Juniper:

  • Maintenance free “à la mode” network management with Sky Enterprise
  • Open telemetry and configuration APIs for automation with JTI and JET
  • Common architectures for campus, private cloud and public cloud with EVPN and VXLAN
  • End-to-end security with SDSN

In this first of a two part blog, I cover the first two essential solutions.


Maintenance Free “À La Mode” Network Management

Juniper Sky Enterprise, a cloud managed service, empowers modern distributed enterprises. The service is designed to automate deployment of campus and branch devices with self-discovery and self-configuration. Distributed enterprises have traditionally relied on long planning cycles, careful pre-staging of devices, presence of local IT at remote branch locations during deployment and expensive ongoing management. This leads to the high cost of installation and maintenance. Sky Enterprise simplifies the deployment process by building in phone-home capability for branch secure routers and switches, eliminating prestaging and enabling centralized management from a focal IT operations center. Sky Enterprise supports SRX Series secure routers and EX Series switches and, where required, it allows customization from the operations center.

Open Telemetry and Configuration API for Automation

Enabling new network capabilities requires extensive telemetry data and configuration APIs that run in real time. The open management interfaces on Juniper devices make this possible. The Juniper Extension Toolkit (JET) provides notification APIs that allows you to subscribe to events and designate a callback function. It also features service APIs giving you access control and management planes to run operational and configuration commands. Additionally, JET gathers network data for contemporary analytics applications, an area where traditional models cannot cope. Future networks will grow to support connectivity to everything and will consume more data required for predictive analysis. Approaches like SNMP and CLI, use a pull model that requires periodic polling of device and impose scale limitations. The Junos Telemetry Interface (JTI) overcomes this limitation by employing a push model to deliver data asynchronously, eliminating the need for polling. This allows a management station to request access to data once and subscribe to streaming periodic updates. Ultimately, JTI allows you to effectively scale to thousands of devices, gathering telemetry data essential for the Self-Driving Network.
