Cloud Spanner is a relational database service that provides trade main 99.999% availability, and close to limitless scale to deal with even probably the most demanding of workloads. For these causes, prospects in numerous industries belief Spanner for his or her workloads with vital throughput necessities. We’ve heard from our prospects that they wish to standardize on Spanner for all their workloads – massive and small as they worth the manageability, scale-insurance, and constant efficiency that Spanner provides.
Subsequently, final 12 months we launched granular occasion sizing in preview as a way to run your workloads on Spanner beginning at roughly $65/month. As we speak, we’re excited to announce the final availability of granular occasion sizing. With granular occasion sizing, at a a lot decrease value you possibly can nonetheless get all the Spanner advantages like clear replication throughout zones and areas, high-availability, resilience to various kinds of failures, and the power to scale up and down as wanted with none downtime. And with Dedicated Use Reductions, the entry worth for manufacturing workload additional reduces to lower than $40/month as you obtain a 40% low cost for a Three-year dedication.
How granular situations work
With granular occasion sizing, we’re introducing a brand new unit for provisioning sources in Spanner – “Processing Items (PUs)” along with “Nodes”. One Spanner node is the same as 1,000 PUs; so you can begin with a 100 PUs occasion and provision in batches of 100 PUs, and get a proportional quantity of compute and storage sources. All Spanner situations together with the situations with lower than 1,000 PUs or 1 node have the identical availability SLA of 99.99% for regional situations and 99.999% for multi-regional situations. You should use this characteristic to cost-effectively run workloads of all sizes on Spanner and scale seamlessly as wanted.
With granular occasion sizing you get proportional sources for proportional worth, for instance, a 100 PUs Spanner occasion can help a most of 10 databases with as much as ~410 GB of information storage. The restrict for variety of databases per Spanner occasion scales proportionally with the provisioned compute capability within the occasion to a most of 100 databases per occasion. Moreover, a Spanner occasion can retailer limitless information so long as adequate compute capability is provisioned within the occasion as there’s a restrict of 4TB of information per 1,000 PUs (1 node).
You may simply use granular occasion sizing by choosing the occasion configuration, Processing Items (PUs) because the unit of compute capability after which offering their amount. The abstract on the best facet of the console-page shows the per-hour compute value primarily based on the variety of Processing Items; it additionally lists the utmost storage which is obtainable for the occasion.
