LambdaReplicaCLI

This repository contains artifacts of the EuroSys '26 paper "Serverless Replication of Object Storage across Multi-Vendor Clouds and Regions" and exposes a command line interface.

1. Configure Python environment

cd LambdaReplicaCLI
pip3 install -e .

2. Install and configure Azure CLI

Because Azure Python SDK cannot fully automate FunctionApp deployment, we use Azure CLI for deployment.

For Mac users:

brew update && brew install azure-cli

For Linux users, please refer to Install the Azure CLI on Linux.

After Azure CLI is installed, run:

az login --service-principal \
  -u <client_id> \
  -p <client_secret> \
  --tenant <tenant_id>

3. Configure LambdaReplicaCLI

lambda-replica-config

Your will need to provide:

• AWS Access Key
• AWS Secret Key
• AWS Role ARN (AWS Lambda functions use this. It must be able to read and write S3 buckets and DynamoDB tables)
• Azure Subscription ID
• Azure Client ID
• Azure Tenant ID
• Azure Client Secret
• Azure Resource Group
• The path to your GCP Credentials (which is an auto-generated JSON file)

4. Run LambdaReplicaCLI

To replicate the object 1M.dat from the bucket lambda.replica.test.us-east-1 at AWS to the container lambda-replica of storage account lreastus at Azure, run:

lambda-replica --source-cloud AWS \
--source-bucket lambda.replica.test.us-east-1 \
--object-key 1M.dat \
--destination-cloud Azure \
--destination-bucket lreastus/lambda-replica
