Google cloud CDN pricing details on cache data size and automatic cache invalidation

Question

I was learning about google cloud CDN and is satisfied with the drop in price difference for egress but some info is missing in pricing documentation

• Will cache entries that is automatically removed after expiration of 30 days be charged under $0.005 per cache invalidation section ?
• Is there any cost for amount of data(GB/TB) stored in cache over a period of time ? (eg -> 1TB for 1 month)

Answer 1

You'll be charged for cache fill when something is inserted into cache, but there is no charge for ongoing storage space used. There's also no charge for evictions. cloud.google.com/cdn/pricing lists what Cloud CDN charges for:

• Cache egress
• Cache fill
• Cache lookup requests
• Cache invalidation

If it's not listed, Cloud CDN doesn't charge for it. The page notes you'll be "charged for any cache invalidations you initiate" [emphasis mine], so you don't need worry about being charged when Cloud CDN evicts a 30-day-old cache entry.
