Explain DAAS and NAAS?
DaaS – Data as a Service :
Since you can get software as a service it seems reasonable to think you should be able to get data as a service as well. DaaS providers collect and make available data on a wide range of topics, from economics and finance to social media to climate science. Some DaaS providers offer application programming interfaces (APIs) can provide on demand access to data when bulk downloads are not sufficient.
Network as a Service (Naas):
Network as a Service (NaaS) is sometimes listed as a separate Cloud provider along with Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). This factors out networking, firewalls, related security, etc. from IaaS.
NaaS can include flexible and extended Virtual Private Network (VPN), bandwidth on demand, custom routing, multicast protocols, security firewall, intrustions detection and prevention, Wide Area Network (WAN), content monitoring and filtering, and antivirus. There is no standard specification as to what is included in NaaS. Implementations vary.
