Juniper : Introduction to the Junos Operating System: May 2015

Sunday 24 May 2015

Junosphere

Cloud-based network testing, design, and training environment

A cloud-based service that allows networking professionals to perform network testing, design, and training exercises in a risk-free virtual environment using real network operating systems.

Overview

Junosphere Cloud is a virtual environment where users can create and run networks that use the Junos operating system. It reduces costs and limits risk by providing a lab where network implementations can be designed and modeled.

Virtual networks created in Junosphere can be used for training, network modeling, planning for new services, or examining “what-if” scenarios for the installed network. They can easily achieve a level of scale and accuracy not possible with alternative network simulation approaches.

Features

SaaS Platform provides maximum uptime and availability.
Efficient Scale enables larger networking resources for more accurate networks and topologies and reduced student-to-equipment ratio.
Demand-Based Pricing allows purchase of Junosphere access based on time and network size.
Real Operating System gives Junosphere users access to the same full-featured Junos OS running in thousands of commercial networks.
Flexible Network Designs include a variety of options for network topology design, including importing configurations from a live network, a graphical design wizard, and text-based configurations.
Flexibility and Agility allow virtual resources to be modified, ordered, and implemented much more quickly than physical networks.
Interoperability and Integration enable virtual resources to interoperate with real-world networks.
Complete Lab Ecosystem provides access to a variety of partner tools, in addition to Junos OS network elements.

** WARNING: THIS DEVICE HAS BOOTED FROM THE BACKUP JUNOS IMAGE      **

** Please re-install JUNOS to recover the primary copy in case      **
** it has been corrupted.                                           **
**                                                                   **
