Current State of Networking

Network management has persistently adhered to traditional methods for decades despite the evolution of underlying technologies. The conventional approach involves manual construction, operation, and maintenance of networks. Network operators, commonly known as NetOps, engage in the repetitive process of logging into routers, switches, load balancers, and firewalls, manually adjusting configurations, and subsequently logging out.

These actions usually aim to enforce and sustain network policies as dictated by business processes. Despite remarkable progress in software-defined networking and services, this established routine has endured for various reasons.

Manual configurations and hands-on management have long been the norm in traditional networking. This conventional approach, relying on human interventions for network operations, contrasts with the evolving methods of automated solutions.

Traditional Approach of Networking

Conventional manual methods for configuring and updating networks are insufficiently paced and prone to errors, making them ill-suited to meet the dynamic demands of rapidly evolving design and applications as well as developer needs. These labor-intensive procedures pose challenges in various areas, including:

  • Ensuring a high level of service for users
  • Provisioning resources to modern application development and IT operation teams
  • Enforcing change control and configuration processes effectively
  • Gaining a comprehensive understanding of inventory and managing it efficiently
  • Upholding configuration standards across diverse network platforms
  • Cultivating proactive and self-reliant NetOps teams

In response to the limitations of traditional networking approaches, network automation emerges as a dynamic solution, revolutionizing how organizations tackle longstanding challenges and simplify network management.

What is Network Automation?

It refers to using technology to automate the configuration, management, testing, deployment, and operation of network devices and infrastructure. Traditionally, network tasks were performed manually, making them time-consuming, fault-prone, and often limited in scalability.

Network automation tools replace these manual processes with intelligent and programmable solutions, allowing organizations to achieve higher efficiency, reduce human flaws, and improve network performance.

The imperative to automate networks has become increasingly evident in the face of escalating complexity and dynamic demands. As technology advances and businesses strive for bolstered efficiency, the need for automation arises to address the challenges posed by manual network management.

This empowers IT and data professionals to focus on strategic initiatives rather than routine configurations, leading to a faster and more agile response to business requirements.

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 –

  • Software-based

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.

  • Script-driven

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.

  • Intent-oriented

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.
