Does SQLite Work With AWS?
SQLite works with AWS, but it's not ideal for distributed systems—use it for local development, edge computing, or embedded scenarios within AWS services.
Quick Facts
How SQLite Works With AWS
SQLite and AWS can coexist, but they solve different problems. SQLite is a file-based, single-machine database excellent for development, testing, and embedded use cases. On AWS, you'll typically use SQLite in three ways: (1) locally on EC2 instances for application state, (2) bundled with Lambda functions for read-only lookups, or (3) as part of mobile/edge applications syncing with AWS services via DynamoDB or RDS. The developer experience is seamless for local workflows, but SQLite's file-locking limitations and single-writer design make it unsuitable for multi-instance production workloads on AWS. Most developers transition from SQLite during development to RDS (PostgreSQL/MySQL) or DynamoDB in production. For serverless functions, SQLite can work in Lambda's /tmp directory for ephemeral data, but you'll hit performance walls quickly. Consider SQLite on AWS as a stepping stone or specialized tool, not a primary database strategy.
Best Use Cases
Quick Setup
pip install sqlite3 boto3import sqlite3
import boto3
from datetime import datetime
# Local SQLite for development
conn = sqlite3.connect(':memory:')
cursor = conn.cursor()
cursor.execute('''
CREATE TABLE events (id INTEGER PRIMARY KEY, name TEXT, timestamp TEXT)
''')
cursor.execute("INSERT INTO events (name, timestamp) VALUES (?, ?)",
('app_start', datetime.now().isoformat()))
conn.commit()
# Sync to DynamoDB for production
dynamodb = boto3.resource('dynamodb', region_name='us-east-1')
table = dynamodb.Table('events')
for row in cursor.execute('SELECT * FROM events'):
table.put_item(Item={'id': row[0], 'name': row[1], 'timestamp': row[2]})
conn.close()Known Issues & Gotchas
File persistence in Lambda—/tmp directory is ephemeral and gets wiped between invocations
Fix: Use Lambda layers for read-only SQLite databases, or store data in S3/DynamoDB instead
Multiple EC2 instances cannot safely share a single SQLite database file over network storage (EBS/EFS)
Fix: Deploy RDS for multi-instance scenarios, or use SQLite only on individual instances
SQLite write-locking causes performance degradation under concurrent load
Fix: Use read replicas with WAL mode, or migrate to RDS PostgreSQL for write-heavy workloads
No built-in AWS authentication—you must manage file permissions manually on EC2
Fix: Use IAM roles for EC2 instance access control, not database-level credentials
Alternatives
- •PostgreSQL RDS + AWS—fully managed relational database with multi-instance support
- •DynamoDB + AWS—serverless NoSQL database native to AWS ecosystem
- •Aurora Serverless—auto-scaling relational database for variable workloads
