Most people only think clouds contain ec2 ,cpc,s3 and lambda but it's much deeper than that . Developers should know about these useful services that are provided by AWS .

4️⃣ TDS (Total Data Size) Awareness Keep an eye on your RDS storage usage. Larger TDS = longer backup times and higher costs. Optimize tables, indexes, and purge old data.

3️⃣ Point-in-Time Recovery (PITR) Combined with automated backups, PITR lets you restore your database to any second within your retention window. Critical for accidental deletes or corruption.

2️⃣ Hardcoding Access Keys in Code or EC2 Stop pasting credentials into .env or config files. Use IAM roles with temporary credentials — it’s what they’re made for.
