Storage Transfer Service supports TLS 1.3 for all HTTPS communication.\n- Data integrity validation ensures that your data is not corrupted during transfer.\n\n**Performant**\n\n- Highly-parallelized architecture accelerates transfer speeds.\n- Automatic retries and load balancing ensure reliable transfers.\n\n**Fully managed**\n\n- No need to manage infrastructure or write code.\n- Focus on your applications, not data transfer.\n\nGet started\n-----------\n\nCheck to see if your\n[source and sink combination is supported](/storage-transfer/docs/sources-and-sinks).\n\nThere are a number of ways that you can work with Storage Transfer Service:\n\n- The Google Cloud console\n- REST APIs\n- The `gcloud` command-line tool\n- Java and Python client libraries\n\nSee [Create transfers](/storage-transfer/docs/create-transfers) to get started.\n\nService Level Agreement\n-----------------------\n\nStorage Transfer Service does not provide an SLA, including for transfer performance or\nlatency, and some performance fluctuations may occur."]]
