Varnish Cache
Varnish Cache is a web application accelerator also known as a caching HTTP reverse proxy. You install it in front of any server that speaks HTTP and configure it to cache the contents.

Network automation

For network automation we need:
- A programmatic interface for device configuration.
- Separation between configuration and operational data.
- Integrated error checking and recovery.
There are three network automation protocols that meet these requirements:
NETCONF is a protocol developed by IETF to “install, manipulate, and delete the configuration of network devices”. The goal of NETCONF is to make network automation easier. It uses XML for data encoding and Remote Procedure Call (RPC) for messages. It runs over SSH.
RESTCONF is protocol which works similar to a REST API. It maps a YANG specification to a RESTful interface and uses the HTTPS protocol for transport. You can use JSON or XML as data formats. RESTCONF is newer than NETCONF but not a replacement. It’s more of a lightweight option for engineers who are familiar with REST APIs. YANG data models can be found in the YANG git repository.

The pivotal deployment of 5G and network slicing has triggered the need for a radical change in the way networks and services are managed and orchestrated. Full end-to-end automation of network and service management has become an urgent necessity for delivering services with agility and speed and ensuring the economic sustainability of the very diverse set of services offered by Digital Service Providers. The ultimate automation target is to enable largely autonomous networks which will be driven by high-level policies and rules; these networks will be capable of self-configuration, self-monitoring, self-healing and self-optimization without further human intervention. All this requires a new horizontal and vertical end-to-end architecture framework designed for closed-loop automation and optimized for data-driven machine learning and artificial intelligence algorithms.
