Pro: Known & trusted by all. No one ever got fired for choosing AWS.
Con: Complicated billing & management UI.
Pro: Fixed $5 plan with lots of headroom to grow. Offers 250 GB storage and 1 TB outbound traffic. Does not charge for requests. First 2 months free. API-compatible with AWS S3.
Con: Only available in NYC & AMS regions. New product, unproved?
OVH Object Storage
Pro: Cheap metered pricing. Also already applied to their startup programme for free credits. Would be great to try out and eventually also deploy DNS and/or edge nodes as VPS and/or dedicated machines.
Con: First impression is a buggy registration/website. Not sure about APIs/docs/support.
