Databricks vs Amazon SageMaker: ML Development Showdown

Overview

Databricks is a Spark-based platform for data engineering, ML, and lakehouse analytics with collaborative notebooks.

Amazon SageMaker is an AWS service for end-to-end ML, focusing on model training, deployment, and MLOps.

Both enable large-scale ML: Databricks emphasizes collaboration and data lakes, while SageMaker prioritizes MLOps and AWS integration.

Fun Fact: Databricks’ notebooks support 1M+ concurrent users!

Section 1 - Mechanisms and Techniques

Databricks uses Spark and MLflow for distributed training—example: Trains a 1PB dataset in 3 hours on 500 nodes with spark.ml.

from pyspark.ml.classification import LogisticRegression lr = LogisticRegression() model = lr.fit(spark.read.parquet("s3://data/"))

SageMaker leverages built-in algorithms and containers—example: Deploys a 1M-row model in 20 minutes on 10 EC2 instances with sagemaker.estimator.

from sagemaker.estimator import Estimator estimator = Estimator(image_uri="XGBoost", role="SageMakerRole") estimator.fit({"train": "s3://data/train.csv"})

Databricks scales to 1M+ jobs with 99.9% uptime; SageMaker handles 10K+ models with 99.9% reliability. Databricks is collaborative; SageMaker is streamlined.

Scenario: Databricks processes a 1PB lake; SageMaker deploys a 1M-row model.

Section 2 - Effectiveness and Limitations

Databricks is powerful—example: Trains 100K models in 4 hours with 99.9% SLA, but Spark overhead adds 15% latency for small datasets.

SageMaker is efficient—example: Deploys 5K models in 15 minutes with 99.9% reliability, but lacks native data engineering (20% slower for ETL).

Scenario: Databricks powers a 1PB ML pipeline; SageMaker stumbles on data prep.
