Secara default, Memorystore untuk Valkey mendistribusikan node instance secara merata di antara
zona yang tersedia. Untuk diagram yang menunjukkan cara node didistribusikan dengan penyiapan ini, lihat Ketersediaan tinggi dan replika.
Atau, Anda dapat memilih untuk membuat instance zona tunggal. Instance zona tunggal
memiliki latensi yang lebih rendah daripada instance multi-zona karena Anda dapat menempatkan
klien di zona yang sama dengan node Valkey dan menghindari komunikasi
lintas zona.
Anda memilih mode distribusi zona (satu zona atau multi-zona) selama pembuatan instance. Setelah dibuat, mode distribusi zona tidak dapat
diubah.
Jika Anda terhubung ke instance satu zona dari klien di zona yang sama, Anda tidak akan ditagih untuk Pemrosesan Data Konsumen.
Untuk informasi selengkapnya, lihat Harga jaringan.
Meskipun kami merekomendasikan penyediaan instance multi-zona dengan Ketersediaan Tinggi, Anda harus menggunakan rekomendasi berikut untuk instance satu zona jika berlaku untuk Anda:
Jika memilih untuk menyediakan instance satu zona, Anda harus mengaktifkan replika. Replika mengurangi hotspot shard dan membuat shard lebih
tangguh terhadap kegagalan node tunggal.
