Lokasi multi-region terdiri dari kumpulan region yang ditentukan tempat beberapa replika database disimpan. Setiap replika adalah replika baca-tulis yang berisi semua data dalam database atau replika saksi yang tidak mempertahankan kumpulan data lengkap, tetapi berpartisipasi dalam replikasi.
Dengan mereplikasi data antara beberapa region, data
dapat terus ditayangkan bahkan jika seluruh
region hilang. Dalam satu region, data direplikasi ke berbagai
zona sehingga data dapat terus ditayangkan
di dalam region tersebut bahkan jika suatu zona hilang.
Setiap lokasi multi-region mencakup minimal dua region baca-tulis yang menyalurkan
traffic baca dan tulis. Region ketiga adalah region saksi di nam5 dan
region baca-tulis di eur3.
