+OAuth stands for **O**pen **Auth**orization and is an open standard for authorization. It works to authorize devices, APIs, servers and applications using access tokens rather than user credentials, known as "secure delegated access".
+
+In its most simplest form, OAuth delegates authentication to services like Facebook, Amazon, Twitter and authorizes third-party applications to access the user account **without** having to enter their login and password.
+
+It is mostly utilized for REST/APIs and only provides a limited scope of a user's data.

+A Content Delivery Network (CDN) service aims to provide high availability and performance improvements of websites. This is achieved with fast delivery of website assets and content typically via geographically closer endpoints to the client requests.
+Traditional commercial CDNs (Amazon CloudFront, Akamai, CloudFlare and Fastly) provide servers across the globe which can be used for this purpose.
+Serving assets and contents via a CDN reduces bandwidth on website hosting, provides an extra layer of caching to reduce potential outages and can improve website security as well
