Understanding Cloud-Native Network Management
Cloud-native network management refers to the use of cloud-native technologies and platforms to create and manage a network. It leverages cloud-native network functions (CNFs) built using containerized microservices running on shared hardware, offering greater elastic scalability and software agility due to advanced management and orchestration capabilities.
Multi-Cloud Networking Principles
Multi-cloud networking involves the seamless integration and management of network resources across multiple cloud service providers. This approach enables organizations to select the best services from various vendors for specific use cases, reducing vendor lock-in and enhancing flexibility.
Cloud-Native Network Functions (CNFs)
CNFs are designed to operate within cloud environments, utilizing microservices architectures and containerization. They offer improved scalability, agility, and resilience compared to traditional network functions, making them essential components in modern network management.
Container Networking
Container networking facilitates communication between containerized applications, ensuring efficient data flow and connectivity. It is crucial for maintaining application performance and reliability in cloud-native environments.
Service Mesh Architecture
A service mesh is a dedicated infrastructure layer that manages service-to-service communication within a microservices architecture. It provides functionalities like load balancing, service discovery, and traffic management, enhancing the observability and security of services.
Cloud Network Security
Ensuring security in cloud-native networks involves implementing measures such as intrusion detection, firewall management, and access control to protect networks from threats. Cloud-based network management tools offer these security management features to ensure network security and compliance with regulatory standards.
