DNS (Domain Name Service) is what translates internet hostnames to addresses.
8.8.8.8 is a free Google public DNS.
Cloud DNS
- DNS service for internet hostnames and addresses of applications built in Google Cloud
- managed DNS service (like AWS Route53)
- runs on the same infrastructure as Google
- has low latency
- high availability
- cost-effective way to make our applications and services available to our users
- DNS information we publish is served from redundant locations around the world
- programmable: we can publish and manage millions of DNS zones and records using the Cloud Console, the command-line interface, or the API.
Edge caching refers to the use of caching servers to store content closer to end users.
Cloud CDN
- Google's global system of edge caches (like Amazon CloudFront)
- Used to accelerate content delivery in our application
- our customers will experience lower network latency
- the origins of our content will experience reduced load
- can be enabled with a single checkbox, after HTTP(S) Load Balancing is set up
Some other CDNs are part of Google Cloud’s CDN Interconnect partner program, and we can continue to use it.
