What Is Network Automation

Network automation is the process of controlling network configuration, management, and operations using software-defined techniques, orchestration platforms, and other automation tools. It entails replacing manual, repetitive tasks with automated workflows, resulting in increased efficiency, accuracy, and agility. 

Network automation, at its core, seeks to simplify and streamline network operations by reducing human involvement and reliance on manual configuration. It enables organizations to automate routine tasks such as network device provisioning, configuration changes, policy enforcement, and monitoring by leveraging programmable infrastructure, software-defined networking (SDN), and automation platforms.

Components of Network Automation

Some foundational elements are essential to implement and operate network automation solutions. The components listed below can help facilitate automation and ensure network management success.

  1. Orchestration and Automation Platforms: These platforms provide a centralized control mechanism for defining, and managing network policies and workflows. Administrators can use them to automate complex network tasks, ensure consistent configurations, and enforce policy compliance across the network infrastructure.
  2. Software-Defined Networking (SDN): Traditionally, network devices tightly connect control functions with physical hardware, but SDN separates the control plane from physical devices, making network management more flexible and programmable. SDN unifies the management and control of various network software elements. 
  3. Network Monitoring and Analytics: Automated network monitoring tools collect real-time data on network performance, traffic patterns, and security events. These tools use analytics with machine learning techniques to detect network issues and trigger automated remediation actions, reducing the need for manual troubleshooting
  4. Network Configuration Management (NCM): NCM refers to the automated configuration and management of network devices such as routers, switches, and firewalls. This includes tasks like initial device provisioning, software upgrades, and policy enforcement to ensure consistent and secure network configurations.
  5. Network Virtualization and Abstraction: Virtualization technologies are used in network automation to separate and abstract network resources, allowing for dynamic network allocation and provisioning. This speeds up network service deployment and improves network scalability and flexibility.

Network Automation Use Cases

Network automation serves to help organizations streamline operations, improve security, and improve network performance in various industries. Here are some common scenarios in which network automation is advantageous: 

  1. Network security and compliance: Network automation is critical for improving network security and ensuring industry compliance. Automatic enforcement of security policies across the network reduces the risk of misconfiguring the network and creating vulnerabilities. Automating monitoring, threat detection, and quick responses to any security incidents that occur improves the overall network security posture. Compared to implementing security measures manually, network automation streamlines and strengthen security.
  2. Network troubleshooting and remediation: Automated networks facilitate monitoring and analytics that proactively detect network issues and anomalies. Based on predefined rules and policies, network automation can initiate responses and remediation actions. This capability enables faster troubleshooting, issue resolution, and more proactive network maintenance, compared to manual execution, resulting in reduced network downtime and improved performance.
  3. Zero-touch provisioning (ZTP): ZTP is a use case in which the initial setup and configuration of network devices have little to no manual intervention. ZTP enables vendors to ship network devices directly to deployment sites. These devices automatically self-configure upon connection to a network. This reduces deployment time and improves consistency by eliminating the need for manual device configuration.
  4. Cloud and hybrid environments: In cloud and hybrid environments, where network infrastructure is distributed and dynamic, network automation is critical. It enables the seamless provisioning and management of network resources such as virtual networks, load balancers, and security groups in cloud environments. It also makes network connectivity and orchestration between on-premises infrastructure and public cloud services more convenient.

Network Automation Benefits

Network automation provides a number of advantages that improve network management and operational efficiency. Organizations can gain the following benefits by leveraging advanced technologies to automate manual tasks: 

  • Fewer manual configuration tasks and human errors: Manual configuration introduces the risk of human errors, which can have serious consequences for network stability and security. Network automation eliminates these errors by enforcing standardized configurations for network consistency, stability, and security.
  • Faster and more accurate provisioning of network resources: Network automation enables rapid and consistent provisioning of network resources by eliminating manual deployment and configuration of devices and services. Using predefined templates and workflows to make provisioning faster means a shorter time-to-market for new network services It also improves agility when responding to changing business needs.
  • Increased operational efficiency: Automating routine and repetitive tasks increases efficiency, which frees up network teams to focus on higher-value activities, like strategic planning, innovation, and resolving critical network issues. It allows for faster service delivery, lowers operational costs, and a boost in overall productivity.
  • Scalable and agile network management: As networks become larger and more complex, manual management becomes more difficult and time-consuming. By automating processes such as device provisioning, network policy enforcement, and resource allocation, organizations can scale their networks efficiently. This helps organizations adapt to changing business needs while also accommodating the dynamic nature of modern networks.

Network Automation


While network automation provides numerous benefits, implementing it presents a number of challenges that organizations must address. Here are some of the most common network automation challenges: 

  1. Security risk considerations: Although automation eliminates human errors that may lead to security risks, there can also be new security challenges, such as possible vulnerabilities in automation tools, unauthorized changes to automated workflows, and improper access controls. Organizations must implement strong security measures, such as strict access control, encryption, audit trails, and regular vulnerability assessments. Furthermore, careful planning and testing are necessary to reduce the security risks associated with automation.
  2. Skillset and training requirements: Network automation requires network administrators and IT teams to acquire new knowledge and skills. For example, they must learn about automation platforms, gain skills with new programming languages, and understand software-defined networking. Organizations must invest in training programs in order to upskill their workforce and enable them to design, implement, and manage automated networks effectively.
  3. Complexity and learning curve: Understanding and implementing various technologies, protocols, and tools is essential for network automation. The learning curve can be difficult at first, and organizations may face difficulties designing efficient and flexible automated workflows. It’s critical to invest time in designing robust automation processes that are constantly improved and optimized.
  4. Legacy system integration and compatibility: Many organizations have a legacy network infrastructure that may or may not be compatible with automated systems. Integrating automation with legacy systems requires careful planning, retrofitting, and potentially, gradual migration to automation-friendly network architectures.
  5. Vendor and tool selection: Choosing the right automation tools and vendors can be difficult due to the market’s abundance of options. When selecting automation vendors and tools, organizations should assess requirements and consider scalability, compatibility, support, and long-term viability.
