Network services are essential applications that facilitate connectivity and communication within a network, enabling users to access data and applications from various locations, including offices and remote sites. These services typically operate at the network application layer and are provided by servers, which can run multiple services simultaneously.Key types of network services include:

• Internet and Cloud Connectivity: Ensures reliable access to cloud applications and resources, supporting remote work and collaboration.
• File and Print Sharing: Allows users to share files and access printers over the network, enhancing productivity and resource utilization.
• Directory Services: Manages user credentials and permissions, enabling authentication and authorization across the network.
• Voice over Internet Protocol (VoIP): Facilitates voice communication over the internet, reducing costs and improving flexibility.
• Content Delivery Networks (CDNs): Optimizes the delivery of content and applications by replicating data closer to users, improving performance and reducing latency.

With the rise of remote and hybrid work models, organizations are increasingly adopting flexible solutions like Network as a Service (NaaS) and Secure Access Service Edge (SASE) architectures. These innovations simplify network management, enhance security, and ensure reliable access to applications, regardless of the user’s location or device.
