Yandex Object Storage
S3-compatible cloud object storage from Yandex Cloud. Replicates data across multiple availability zones with a **99.98% SLA**, supports standard + cold storage tiers, and ships with compliance attestations for Russian law (152-FZ), GDPR, ISO, and PCI DSS. API surface matches AWS S3 closely enough that standard S3 tooling (boto3, s3cmd, WinSCP, AWS SDKs) works without code modification.

S3-compatible cloud object storage from Yandex Cloud. Replicates data across multiple availability zones with a **99.98% SLA**, supports standard + cold storage tiers, and ships with compliance attestations for Russian law (152-FZ), GDPR, ISO, and PCI DSS. API surface matches AWS S3 closely enough that standard S3 tooling (boto3, s3cmd, WinSCP, AWS SDKs) works without code modification.
Russian and CIS-region workloads have hard data-residency requirements that effectively forbid storing data on US-cloud infrastructure under Russian privacy/security law (152-FZ). Yandex Object Storage is the dominant in-jurisdiction S3-compatible option for those customers. Outside of the residency story, the value proposition mirrors most regional S3 alternatives — multi-AZ replication, S3 API parity, and compliance attestations that map to local regulatory regimes.
Russian / CIS-region workloads with mandatory in-country data residency, GDPR-compliant storage for EU customers of Yandex's European data centers, backup and archive targets for Yandex Cloud compute workloads (intra-cloud egress optimized), S3-compatible target for backup tools requiring 152-FZ compliance, and developer-tier projects on the broader Yandex Cloud platform.
Recent developments
Flat 8% price increase May 1, 2026 (10% on network/non-replicated SSDs) — the "sovereignty premium" made visible. Object Storage, managed databases, and NLBs all rose in lockstep; post-Nebius-split, Yandex Cloud serves a captive domestic market where 152-FZ data-localization law and Western-provider exits mute price competition. Free tier holds at 1 GB storage / 10K PUT / 100K GET / 100 GB egress monthly; Ice Storage carries a 12-month minimum billable duration. Per Yandex Cloud — 2026 pricing update and Yandex Cloud and the sovereignty premium (BTW Media).
Intelligent tiering matured + buckets mountable as filesystems in Cloud Functions (2026). Auto-tiering moves objects FREQUENT → INFREQUENT at 30 days idle → ARCHIVE at 90, restoring on access; serverless functions can now mount buckets as filesystems — the same POSIX-on-object convergence pattern as S3 Files, arriving in the sovereign segment. Per Yandex storage classes and Cloud Functions release notes.
99.98% multi-AZ replication SLA, with encryption-at-rest by default. Data is replicated across multiple availability zones; each replica is updated synchronously on create/modify/delete. Per Yandex Cloud — S3 storage service.
Compliance attestations: 152-FZ, GDPR, ISO, PCI DSS. Data kept encrypted in compliance with the applicable laws, regulations, and standards. Per Yandex Cloud — services/storage.
Two-tier storage model — standard + cold. Standard storage for actively used objects, cold storage for rarely-accessed data at reduced cost. Per Yandex.Cloud pricing.
Full S3 API compatibility — boto3, CLI, WinSCP, Java/Python SDK. Drop-in for standard S3 tooling without code changes beyond endpoint reconfiguration. Per Yandex Cloud storage docs.
