But have you ever wondered what makes network automation a cardinal aspect of today’s IT operations? Well, the answer lies in its extensive roster of sub-disciplines.
Setup and Customization: Network programmability, for instance, allows for customization, while network provisioning deals with the setup, configuration, and management of a network resource. These automations contribute to faster, more efficient, and impeccably predictable network operations.
Standardize Procedures: Critical components such as network automation ensure a concerted operation. A network automation framework is used to standardize procedures and maintain consistency across the network. We find network workflow automation among its vast toolkit for streamlining and managing network tasks or processes, enabling more efficient execution of repetitive tasks.
Network Automation: Have you ever wondered about network policy and infrastructure automation? Policy automation helps in automating the application and enforcement of network security policies. On the other hand, infrastructure automation ensures automated tasks within the network’s physical hardware or virtual aspects, including network virtualization.
Network Management and Autonomicity: When further improving networking operations, practices like network intent-based management and network autonomicity take center stage. Intent-based networking (IBN) uses machine learning and advanced analytics to automate administrative tasks. The concept of network autonomicity goes a step further by enabling the network to manage, configure, heal, and protect itself autonomously.
Network Monitoring and Change Management: What if issues arise? The answer rests with network change management alongside network monitoring automation. They play a pivotal role in detecting and resolving network issues and reducing manual labor. Network troubleshooting automation likewise allows professionals to identify and fix network-related problems automatically.
Network Optimization and Security Automation: Finally, network optimization and security automation sectors focus on enhancing network performance and safeguarding networking assets against potential threats. Network optimization improves network speed, reliability, and capacity, while network security automation implements measures to protect the network from cyber threats.
Networking Automation is an encompassing term that signifies the confluence of numerous subsets that collectively contribute to a frictionless, automated, and efficient networking environment.
Examples of Networking Automation (NA)
Cisco Systems Inc.
In Cisco Systems Inc., network automation is implemented using software-defined networking (SDN). SDN has eliminated the tedious manual workload of configuring its extensive network infrastructure, enhancing its capability to swiftly adapt to changing business needs. The software swiftly spots network issues, decreases downtime, and curbs the risk of human errors in configuration tasks.
Google’s Site Reliability Engineering
Another networking automation utilization case is in Google’s Site Reliability Engineering (SRE). SRE work in Google involves creating a self-healing infrastructure incorporating machine learning and automation. This allows for operations like traffic shifting, automatic error identification, and automated rollouts to be handled by systems, not people, reducing the chance of human error.
Amazon Web Services (AWS)
Amazon Web Service’s (AWS) Cloud Development Kit (CDK) presents a real-world example of networking automation. It enables developers to define cloud infrastructure in code and provision it through AWS CloudFormation. It eliminates the need for manual workloads and enables consistency in resource provision. It allows developers to build, deploy, and manage applications rapidly, simplifying operations and reducing time-to-market.
Best Practices for Networking Automation (NA)
Starting your journey towards network automation requires a systematic and thorough understanding of best practices.
- Explore Network Configuration Automation
The first step is exploring network configuration automation. This involves the use of software tools to change network device settings. Doing so ensures consistency across your system and eliminates the potential for human error. Network automation tools like Python, Ansible, and Chef streamline this process, giving your IT team more time to focus on strategic tasks rather than routine network administration.
- Implement Network Programmability
Next, consider implementing network programmability. This refers to configuring, managing, troubleshooting, and optimizing network devices programmatically. The concept is closely related to software-defined networking, where network control is decoupled from hardware and given to a software application. Network programmability allows for rapid adaptation to ever-changing IT requirements and business goals.
- Deploy Network Automation Framework
Deployment of a resilient network automation framework is critical as it provides the structure for your automation tasks. Key elements of this framework include network scripting for automating frequent commands, network policy automation for implementing rules across your network, and network workflow automation for orchestrating complex sequences of tasks.
- Setup Networks with Network Provisioning
With network orchestration, you unify all processes under one central system, making management more straightforward and efficient. This includes network provisioning, where new systems are set up and configured according to a pre-set template, and network virtualization, which allows for the efficient use of network resources.
- Integrate Network Intent-Based Management
Next, consider integrating network intent-based management, a system that implements high-level business policies and automates network operations to achieve those policies. Compliment this with network autonomicity, where the network self-manages and repairs itself with minimum human intervention.
- Use of SaaS Management Tool
One way to achieve this is with a SaaS management platform like Torii. Torii offers visibility over SaaS expenditures and allows building custom plugins and integrations for cloud apps, which can positively impact your network automation strategy.
- Network Monitoring and Optimization
Finally, consider network monitoring, troubleshooting, optimization, and security automation. These allow for real-time detection and response to network anomalies. Network self-service also enables users to establish and manage their devices on the network autonomously.
Remember that network automation requires a committed and methodical approach and will take time to see measurable results. Don’t rush the process -rigorously test each stage before moving on to the next. Appropriately done, network automation will save time, reduce errors, boost productivity, and provide valuable insights into your networking environment.
