db.t4g.large questions
- Does a db.t4g.large Reserved Instance renew automatically?
- No. AWS Reserved Instances never auto-renew — when the term ends, db.t4g.large reverts to the on-demand rate shown above until you buy again.
- Is a 3-year term worth it for db.t4g.large?
- At the us-east-1 rate shown here, the deepest 3-year offer breaks even in about 17 months. Worth it if this instance type has more runway than that left — Reserver's recommendations look at your actual run history before suggesting 1yr vs 3yr.
