SAN FRANCISCO — Google is back at it, once again lowering prices and adding features for its portfolio of services in its public cloud.

Google has in the past year challenged competitors in the public-cloud market with substantial price cuts and rapid-fire feature and partnership announcements. That pattern isn’t letting up. Which comes back to Google’s statements earlier this year about introducing the concept of Moore’s Law to cloud-infrastructure pricing.

Googlers are invoking Moore’s Law again today in a new wave of price-cutting announcements.

The price of network egress is dropping by 47 percent. The cost of storage of data in the BigQuery Web service is falling by 23 percent. Cloud SQL, Persistent Disk SSD, and Persistent Disk Snapshots are also getting lower prices, by 23 percent, 48 percent, and 79 percent, respectively.

But Google isn’t stopping there. Today it’s adding autoscaling, a feature long expected for the Google Compute Engine.

Also new: peering options as a result of several partnerships, with companies Verizon, Equinix, IX Reach, Level 3, TATA Communications, Telx, and Zayo.

And following Google’s recent acquisition of real-time backend database startup Firebase, Google is introducing “triggers” to create “webhooks” that can connect with application programming interfaces (APIs) based on rules. What’s more, Firebase on the Google Cloud Platform comes with new sorting and filtering capabilities.
