The short version

  • Only Aiven has a free tier, so it costs nothing to try first.
  • Each has a real cost: Aiven the free plan gives 1 VM with 1 CPU, 1 GB RAM and 1 GB storage, and cannot pick a specific cloud or region; Teradata licensing is negotiated rather than published, so there is no way to compare total cost against a consumption-priced warehouse without entering a sales cycle, and the comparison is only ever as good as the workload profile you gave them.
  • They diverge on capability: Aiven covers Multi-cloud Support, Teradata covers Massively parallel architecture.
  • Prices and features above were last checked on 30 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Aiven

  • Running managed open source databases without operating themnot Teradata
  • Multi-cloud deployment across AWS, Google Cloud, Azure, DigitalOcean, OVH and UpCloudnot Teradata
  • Highly available data services with automatic failovernot Teradata
  • Prototyping on a small free instance before scaling upnot Teradata

Teradata

  • A large existing Teradata estate where the practical question is which workloads to migrate first rather than whether to adoptnot Aiven
  • High-concurrency mixed workloads where hundreds of analysts and scheduled jobs contend and predictable prioritisation matters more than peak single-query speednot Aiven
  • Regulated reporting where the same query must produce the same answer for years and the audit trail of the existing implementation has valuenot Aiven
  • Hybrid deployments where regulatory or data-residency rules keep a portion of the warehouse on-premises while the rest moves to cloudnot Aiven

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Aiven

  • The free plan gives 1 VM with 1 CPU, 1 GB RAM and 1 GB storage, and cannot pick a specific cloud or region
  • Free and Developer tiers have no integrations and no connection pooling
  • Connection pooling, database forks and dynamic disk sizing need the Business or Premium plan
  • A 99.99 percent uptime SLA starts at the Startup plan from $75 a month
  • High availability with automatic failover starts at Business from $180 a month

Teradata

  • Licensing is negotiated rather than published, so there is no way to compare total cost against a consumption-priced warehouse without entering a sales cycle, and the comparison is only ever as good as the workload profile you gave them.
  • The SQL dialect and the loading utilities are Teradata-specific, so every stored procedure, macro and BTEQ script written against the platform is migration debt that grows with each release you ship.
  • Primary index choice determines data distribution, and a poorly chosen index concentrates rows on a few processing units, which surfaces as one slow query rather than an error and needs a specialist to diagnose.
  • The skills market is contracting, so DBA and workload-management expertise is expensive to hire, hard to replace when someone retires, and increasingly hard to buy from consultancies whose own bench has moved to cloud warehouses.
  • The 2026 renaming of Vantage, VantageCloud, ClearScape and QueryGrid split documentation, runbooks and vendor material across two naming systems, so searching for an error or a configuration now returns results for a product that is described under a different name.

Answered from the vendors’ own pages

Aiven: What does Aiven's free tier include and does it have any time limit?

The free tier includes PostgreSQL with 1 VM, 1 CPU, 1 GB RAM, and 1 GB storage with access to limited cloud and region selections. There are no time limitations on the free tier, though Aiven reserves the right to shut down accounts that violate policies or remain unused for extended periods.

Teradata: Is Teradata only on-premises?

No. It is sold for cloud, on-premises and hybrid deployment, and the cloud offering is now branded Teradata Cloud. A large part of the installed base is still on-premises or hybrid.

Aiven: How is Aiven billed and what are the monthly costs for each tier?

Aiven bills services by the hour and invoices monthly, charging only for what you actually run. PostgreSQL pricing starts at 5 dollars per month for Developer, 12 dollars per month for Hobbyist, 75 dollars per month for Startup, 180 dollars per month for Business, and 270 dollars per month for Premium. All paid tiers offer hourly billing options as well.

Source
Teradata: How does it compare to Snowflake or BigQuery?

On raw elasticity and cost transparency the cloud warehouses win. On mixed-workload concurrency management against a large existing query estate Teradata is still hard to replace, which is why migrations off it take years rather than quarters.

Aiven: What backup retention periods are included at different Aiven tiers?

Backup retention increases with tier level: Startup tier provides 2 days of backup retention, Business tier offers 14 days, and Premium tier includes 30 days. Point-in-time restore is available on all paid tiers.

Source
Teradata: Why do organisations stay on it?

Because the cost of leaving is the estate, not the data. Thousands of procedures, scripts and extracts written in a proprietary dialect have to be rewritten and revalidated, and in regulated reporting that revalidation is the expensive part.

Aiven: Is high availability included in Aiven pricing or charged separately?

High availability, backups, and routine maintenance are all included in the tier costs with no separate charges. The Business tier includes 2 VMs with automatic failover, and Premium includes 3 VMs with a second standby node.

Source
Teradata: What changed in the 2026 rebrand?

Vantage became the Autonomous Knowledge Platform, VantageCloud became Teradata Cloud, ClearScape Analytics became AI Studio and QueryGrid became Fabric. The underlying products are continuous with what came before.

Aiven: Does Aiven offer a trial period to test premium features?

Aiven offers a 30-day free trial to access premium features beyond what the free plan provides.

Source
Teradata: Can it handle AI and vector workloads?

It has added an Enterprise Vector Store and in-database analytics branded AI Studio. Whether that is preferable to moving the data into a purpose-built vector store depends on how much of your data already lives in the warehouse.
