Storage Transfer Service dapat memproses notifikasi peristiwa di AWS atau Google Cloud untuk otomatis mentransfer data yang telah ditambahkan atau diperbarui di lokasi sumber. Transfer berbasis peristiwa didukung dari AWS S3 atau Cloud Storage, dan selalu menggunakan bucket Cloud Storage sebagai tujuan.
Transfer berbasis peristiwa memproses Notifikasi Peristiwa Amazon S3 yang dikirim ke Amazon SQS untuk sumber AWS S3. Sumber Cloud Storage mengirim notifikasi ke langganan Pub/Sub.
Manfaat transfer berbasis peristiwa
Karena transfer berbasis peristiwa memproses perubahan pada bucket sumber, update
akan disalin ke tujuan secara hampir real time. Storage Transfer Service tidak perlu
menjalankan operasi daftar terhadap sumber, sehingga menghemat waktu dan uang.
Kasus penggunaan mencakup:
Analisis berbasis peristiwa: Mereplikasi data dari AWS ke Cloud Storage untuk
melakukan analisis dan pemrosesan.
Transfer berbasis peristiwa dengan Storage Transfer Service berbeda dengan replikasi Cloud Storage standar dengan membuat salinan data Anda di bucket yang berbeda.
Hal ini memberikan manfaat seperti:
Menyimpan data pengembangan dan produksi dalam namespace terpisah.
Membagikan data tanpa memberikan akses ke bucket asli.
Mencadangkan ke benua lain, atau ke area yang tidak tercakup oleh
penyimpanan dual-region dan multi-region.
Penyiapan DR/HA: Mereplikasi objek dari sumber ke tujuan pencadangan dalam hitungan
menit:
Pencadangan lintas cloud: Membuat salinan cadangan AWS S3 di Cloud Storage.
Cadangan lintas region atau lintas project: Membuat salinan bucket Cloud Storage di region atau project lain.
Migrasi langsung: Transfer berbasis peristiwa dapat mendukung migrasi dengan periode nonaktif yang rendah, dengan
durasi nonaktif beberapa menit, sebagai langkah lanjutan untuk migrasi batch
satu kali.

Event-driven transfers are supported from AWS S3 or Cloud Storage,\nand always use a Cloud Storage bucket as the destination.\n\nEvent-driven transfers listen to [Amazon S3 Event Notifications](https://docs.aws.amazon.com/AmazonS3/latest/userguide/NotificationHowTo.html)\nsent to Amazon SQS for AWS S3 sources. Cloud Storage sources send\nnotifications to a Pub/Sub subscription.\n\nBenefits of event-driven transfers\n----------------------------------\n\nBecause event-driven transfers listen for changes to the source bucket, updates\nare copied to the destination in near-real time. Storage Transfer Service doesn't need\nto execute a list operation against the source, saving time and money.\n\nUse cases include:\n\n- **Event-driven analytics**: Replicate data from AWS to Cloud Storage to\n perform analytics and processing.\n\n- **Cloud Storage replication**: Enable automatic, asynchronous object\n replication between Cloud Storage buckets.\n\n Event-driven transfers with Storage Transfer Service differ from\n [typical Cloud Storage replication](/storage/docs/availability-durability#cross-region-redundancy) by creating\n a copy of your data in a different bucket.\n\n This provides benefits such as:\n - Keeping development and production data in separate namespaces.\n - Sharing data without providing access to the original bucket.\n - Backing up to a different continent, or to an area not covered by dual-region and multi-region storage.\n- **DR/HA setup**: Replicate objects from source to backup destination in order\n of minutes:\n\n - Cross-cloud backup: Create a copy of AWS S3 backup on Cloud Storage.\n - Cross-region or cross-project backup: Create a copy of Cloud Storage bucket in a different region or project.\n- **Live migration**: Event-driven transfer can power low-downtime migration, on\n the order of minutes of downtime, as a follow up step to one-time batch\n migration.\n\nLearn how\n---------\n\n- [Set up event-driven transfers from Cloud Storage](/storage-transfer/docs/event-driven-google).\n- [Set up event-driven transfers from AWS S3](/storage-transfer/docs/event-driven-aws)."]]
