What Is Network Automation?
Slide
Notes
Network automation refers to the process of using software and technology to automate the
configuration, management, and operation of computer networks. It involves using programming,
scripting, and orchestration tools to perform tasks that were traditionally manual and
time-consuming. Automation eliminates human errors, increases productivity, and improves network
reliability.
Automating data center, campus, and cloud networks is more than just the auto configuration of
basic switching and routing functions. It also includes the provisioning of computing resources,
tenants, and customized functions within in an orchestration/abstraction layer at a cloud service
enablement layer.
Arista’s Extensible Operating System ( EOS) facilitates complex IT workflows via open API’s and well
known Linux based scripting interfaces. EOS can be easily integrated into larger workflows where
compute, storage and network services are configured together. Arista EOS rich automation
capabilities not only reduce the human error element in network operations but also enable IT
operators to make the network work the way they want.

Network Automation Use Cases
Slide
Notes
Network automation has a wide range of use cases across various industries and network
environments. Here are some common use cases:
1.
2.
3.
4.
14
Configuration Management: Automation can be used to centrally manage and automate the
configuration of network devices such as routers, switches, and firewalls. This ensures
consistent and standardized configurations across the network.
Provisioning and Deployment: Automation streamlines the provisioning and deployment of
network devices. It can automate the process of adding new devices, configuring them, and
integrating them into the network.
Compliance verification: Automation can enhance network security by automating tasks such
as firewall rule updates, intrusion detection, and prevention system (IDPS) configuration,
security policy enforcement, and threat response.
Cloud Infrastructure as a Service: Automation can be used to add new application,
autonomically by configuring tenant based networking services including VLANs, VxLANS,
custom forwarding groups, ACL’s specific to the security, segmentation and communication
needs.

1.
2.
3.
23
Arista EOS (Extensible Operating System): Arista's flagship operating system, EOS, is designed
with automation in mind. It provides a single modular software image that runs across Arista
switches, routers, and virtualized platforms. EOS supports programmatic interfaces, such as
APIs and scripting languages, allowing for automation and integration with third-party tools.
Arista CloudVision: CloudVision is a network-wide platform that provides a central point of
management and control for Arista's physical and virtual network infrastructure. It offers a
unified view of the network, enabling automation and orchestration of network policies and
configurations.
DevOps Automation: Arista promotes a DevOps approach to network automation, emphasizing
collaboration and integration between network operations (NetOps) and software development
(DevOps) teams. By using modern development practices, such as version control, continuous
integration/continuous delivery (CI/CD), and infrastructure as code (IaC), Arista enables teams
to automate network configurations and workflows in a consistent and agile manner.

EOS & CloudVision for Automation
Slide
Notes
Arista EOS supports scripting using Bash and Python. Administrators can leverage Bash scripting to
automate repetitive tasks, execute commands, and perform operations across multiple devices.
Python scripting is also widely used to automate network configurations and operations by leveraging
Arista's Python SDK and APIs.
Using standards based protocols (e.g. DHCP, T/FTP, HTTP) the network can be rapidly provisioned.
Advanced scripting capabilities allow the administrator to tailor boot configurations based on a
variety of parameters, meeting the needs of even the most complex data center deployments.
Arista provides a Python SDK that simplifies the automation of EOS devices. The SDK offers a set of
Python libraries and APIs to interact with EOS, configure devices, retrieve information, and perform
operations programmatically.

Slide
Notes
CloudVision is Arista’s modern, multi-domain management platform that leverages cloud networking
principles to deliver a simplified NetOps experience. Unlike traditional domain-specific management
solutions, CloudVision enables zero-touch network operations with consistent operations
enterprise-wide, helping to break down the complexity of siloed management approaches.
CloudVision is built on a Network Data Lake (NetDL) architecture that leverages realtime state to
provide an abstraction of the physical network to a broader, network-wide perspective allowing for a
more efficient approach for several operational and network telemetry capabilities including the
following highlights:
The Network API Gateway allows northbound integration, enabling external systems and applications
to interact with the CloudVision platform. It provides APIs and protocols that expose network
information, configuration, events, and other relevant data to the external systems.
Centralized API gateway for both northbound and southbound integrations, leveraging OpenConfig,
gRPC, and REST APIs

CloudVision Configlets are a key feature of Arista's CloudVision platform, specifically
designed to simplify and streamline network configuration management. Configlets are
reusable configuration snippets or templates that define specific network configurations or
policies. They allow network operators to apply consistent configurations across multiple
devices, automate configuration updates, and enforce standardized network settings.

Configlet Builder – Flexible Scripting Engine
CloudVision Portal enables you to create Configlets using two different methods. You can
create Configlets using the CVP Configlet Builder feature, or you can create them
manually. You should use the method that is best suited to your intended use of the
Configlet.
Configlet Builder feature enables you to programatically create device configurations
(Configlets) for devices that have relatively dynamic configuration requirements. This helps
to prevent you from having to manually code Configlets.
The Configlet Builder feature is essentially a set of user interface (UI) widgets and a python
script, that when used together, programatically generate Configlets for a device. The UI
widgets are essential if you want to use the feature to generate Configlets with user input
