# Cost Optimization Overview

ScyllaDB Cloud includes several automatic optimizations that reduce your
infrastructure costs without any configuration required. On top of that,
there are deployment choices you can make to further reduce costs.

## Built-in Optimizations

ScyllaDB Cloud applies the following optimizations automatically for all clusters:

* **SSTable deduplication during backups** — When performing daily backups,
  ScyllaDB Cloud deduplicates SSTables before upload, reducing backup storage
  usage and upload time. See [Backups](https://cloud.docs.scylladb.com/stable/operate/cloud-backup.md).
* **Advanced Internode (RPC) Compression** — All traffic between nodes
  (replication, repair, streaming, coordination) is compressed using
  Zstandard (ZSTD), significantly reducing intra-zone network costs.
  See [Advanced Internode (RPC) Compression](https://cloud.docs.scylladb.com/stable/cost-optimization/advanced-internode-compression.md).
* **Autoscaling** — Clusters scale down automatically when utilization drops,
  so you are not paying for idle capacity. Clusters also target up to 90%
  storage utilization, meaning you get more out of each node compared to
  self-managed deployments.
  See [Autoscaling Behavior and Best Practices](https://cloud.docs.scylladb.com/stable/cloud-setup/cluster-types/xcloud-autoscaling-behavior.md).

## Deployment Choices That Affect Cost

* **Bring Your Own Account (BYOA)** — Deploy ScyllaDB Cloud into your own AWS
  or GCP account to take advantage of your existing reserved instance pricing
  or committed use discounts, and to keep data transfer costs within your
  cloud account.
  See [BYOA for AWS](https://cloud.docs.scylladb.com/stable/cloud-setup/byoa-aws.md) or [BYOA for GCP](https://cloud.docs.scylladb.com/stable/cloud-setup/byoa-gcp.md).
* **Datacenter placement** — When adding datacenters to a multi-DC cluster,
  placing them in the same cloud region as your application reduces
  cross-region data transfer costs.
  See [Datacenter Placement and Data Transfer Costs](https://cloud.docs.scylladb.com/stable/cost-optimization/multi-dc-data-transfer.md).
