Choose a PostgreSQL database plan in Blesta with PD AWS PostgreSQL
Choose a database instance class that suits the application you intend to host through PD AWS PostgreSQL. The plan controls compute and memory; storage and the PostgreSQL engine version need their own review.
Match the plan to the workload
RDS and Lightsail have separate plan sets. The module’s curated RDS plans include Micro, Small, Medium, Large and X-Large. Micro, Small and Medium use the burstable T4g family; Large and X-Large use the M6g family. Medium is not a fixed-performance plan simply because it is larger than Small. Lightsail uses its separate Micro, Small, Medium and Large managed-database bundles; those names do not identify the corresponding RDS class.
AWS explains the baseline and CPU-credit behaviour of RDS instance types. Review sustained CPU demand, working memory and connection load, rather than choosing only by the tier name. A burstable plan can suit intermittent workloads while sustained usage needs closer capacity and provider-cost review.
Save a matching configuration
- Open the package’s Module tab.
- Confirm the intended backing, region and Plan. On Lightsail, use a managed-database bundle; on RDS, use an instance class.
- Review PostgreSQL version and storage for that combination.
- Save and review the actual order or service selections before provisioning.
Availability can change by AWS region, engine version and account. Live lookups may fall back to curated choices when AWS is unavailable, so a displayed plan is not proof that AWS will accept that precise combination.
Keep existing database changes deliberate
Changing a default for new orders is separate from changing an existing database. Do not resize a live application simply to inspect a plan. Review provider readiness, recovery needs and application interruption with the administrator before a supported service change. If provisioning refused the selected class, keep the original service and inspect the recorded result before trying again.
