In this section we will talk about why we need network automation
even as underlying technologies have evolved guys.
Network Management has remained largely same for decades.
Networks are typically built operated and maintained manually network operators look into routers switches
load balancers and firewalls and they change the configurations by day or hand and then they logged
out.
These procedures are largely directed at implementing and maintaining the network policies defined by
business processes at least 70 percent of Gartner clients still use manual CLIA based chains as the
primary mechanism for network configurations
so when it comes to the network program ability guys this is a really technology that's really changing
the landscape of network administration.
It is going to change how and network administrator does day to day jobs and that is SD in which which
is known as Software Defined Networking.
The idea is in here instead of going individual devices such as routers switches and firewalls and configuring
them individually we can express our intent to a network controller and that's network controller could
simultaneously go out and configure multiple devices which gives us a great scalability to be able to
do that and we are going to see how it works in this section.
How do we express our intent to a controller but it can be through a program that we write or maybe
a program written by a third party or maybe a python program or maybe a program that is accessible through
G Y interface built into our controller
so we we told that future going to be the network automation and add traditional manual approaches to
the network configuration and updates are too slow and error prone to effectively support the needs
of rapidly shifting application and data transfer requirements.
These hands on processes make it difficult to provide the high level of service users expect and deliver
resources to applications and I.T. operations teams on demand and implement change control and configuration
processes and understand and manage inventory effectively also maintain configuration standards across
disparate network platforms and buildings stronger and more self-sufficient.
Net ops team programmable software based automation technologies can help your team better support your
organization's digital in the team to use Gartner believes organizations that automate 70 percent of
their network configuration change will reduce the number of unplanned network outages by more than
half compared with those that automate less than 30 percent so way to automate your network why we need
this one reusable scalable software defined.
Automation gives you more control over and visibility into network resources as a result you can improve
infrastructure availability stuff productivity network security and configuration compliance.
Okay let's start with the productivity network.
Automation will improve your team's ability to respond faster to increased demand for changes and also
they will able they will be able to test and deploy changes automatically and they will be able to automate
rapidity you and unpopular their tasks.
When it comes to complaints and network automation will ensure continuous compliance with changing regulations.
You can leave all configurations from a single platform and automatically test changes before committing.
You can also validate that changes were made appropriately or not.
When it comes to security point of view you will be able to identify vulnerabilities and implement fixes
across your entire network.
You can collect information about network to ISIS and the build an inventory of those devices so you
can automatically mitigate the issues when it comes to availability.
You can increase network availability with more effective testing and management and also you can automate
testing to better understand and the impact of change and reduce manual errors with automated change
management.
