Secondly, it minimizes the risk of human-intervened discrepancies, ensuring consistent and accurate network configurations. The reduction of errors leads to increased reliability and controlled network downtime. As businesses scale, the demand for scalability in modern IT infrastructure starts bolstering. Automation facilitates seamless scalability by streamlining processes and adapting to changing requirements with minimal manual intervention.
In the intricate web of network infrastructure, the automation functioning unfolds as a sophisticated orchestration of tasks, replacing manual processes with intelligent and programmable solutions. This transformative approach accelerates operations and introduces a new paradigm in how systems adapt, respond, and thrive in the digital age of networking.
How does Network Automation Work?
It shares similarities with software programming, employing analogous logic and frameworks to oversee and schedule various automated tasks. It involves using common decision statements like “if X, then Y” to encode automation logic within the network. Administrators can utilize tools integrated into the network automation platform or create and run automation scripts for network components using first- or third-party software.
In contemporary Software-defined Networking (SDN) platforms, a centralized control plane is often employed, featuring readily available and pre-configured network automation tasks that are adjustable and can be scheduled as needed. Alternatively, network teams have the option to leverage external tools for scripting, executing these scripts through the command-line interface (CLI) or application programming interface (API).
From configuration management databases to intent-based networking, exploring the spectrum of automation approaches unveils the versatility and depth of networking solutions.
Types of Network Automation
Automation finds applicability across diverse network types, encompassing local area networks, wide-area networks, data center networks, cloud networks, and wireless networks. Here are the types commonly used –
This is commonly known as intelligent network automation, orchestrated through an administrative portal that eradicates the necessity for manually scripting commands. The platform usually furnishes templates for the creation and execution of tasks, aligning with plain language policies.
Automation in networking driven by scripts utilizes scripting and programming languages to carry out tasks, especially those with specific triggers and standardized procedures. Legacy languages like Perl and Tcl are widely used in network automation, primarily because of their established familiarity.
Network administrators establish performance service levels for both applications and users. If these service levels are not met, the network autonomously realigns performance levels of business-critical applications to the best of its ability.
The multitude of network automation advantages not only streamline operations but also empower organizations to navigate the complexities of modern networking with unprecedented agility.
