Scenario

The revolution of the telecommunications ecosystem through Cloud Native solutions marks an epochal moment in the Telco industry. The shift from a monolithic approach to one based on microservices and containers has redefined the delivery of Telco services, enhancing speed, agility, flexibility, and opening up new and challenging opportunities.

Initial implementations on networks relying on monolithic architectures led to the creation of rigid and complex systems, challenging to scale and adapt to the evolving needs of users and the industry. In contrast, the innovative Cloud Native paradigm is based on an approach that fully leverages the potential of cloud infrastructures in software design, development, and distribution.

This transition from a monolithic to a microservices-based approach, coupled with containerization and advanced orchestration, has become possible. Microservices represent modular and independent units, each performing specific functions, in contrast to the rigid previous system, which was a single monolithic unit.

Furthermore, the use of software containers, allowing applications and their dependencies to be packaged in an isolated and portable environment, simplifies uniform distribution across various infrastructures, ensuring process reproducibility.

Orchestration with Kubernetes

A Key Role

Within the Cloud Native scenario, orchestration gains even greater importance as it is necessary for managing the entire infrastructure and workflow of telecommunications services. Kubernetes or K8s, an open-source platform developed by Google, has played a crucial role in revolutionizing container orchestration, automating the deployment, scalability, and management of Cloud Native applications.

Principali caratteristiche:

Key Features:

  • Advanced Orchestration: Automation of provisioning, deployment, and container management on a machine cluster. K8s ensures applications run in the desired state, enabling easy scalability and management.

  • Declarative Approach: After defining the desired state, the system determines how to execute operations to bring the actual state to the desired one. This ensures more predictable application management with fewer errors.

  • Scalability: Kubernetes allows adaptable application management to individual needs, enabling the increase or decrease of container instances based on traffic for optimal performance.

  • Redundancy and Reliability: Kubernetes automatically manages container redundancy. If an instance fails, the tool automatically starts a new one to ensure application reliability.

  • Configuration Management: Application configuration, including environment variables, confidential data, and network settings, can be easily defined through configuration files or manifests. This significantly simplifies the uniform application distribution across various environments.

  • Simplified Updates: Kubernetes allows controlled and gradual application updates, minimizing the impact on running services.
