Ladang Server Facebook yang Melayani Seluruh Dunia




Hasil survei Silverpop yang dimuat dalam Digital Strategi, 27 November 2012 menunjukkan pengguna Facebook telah mencapai 1 miliar anggota. Artinya, jejaring sosial ini masih kuat bercokol di puncak teratas paling banyak dipakai orang.

Menarik untuk diketahui, Pengguna menghabiskan lebih dari 20 miliar menit di Facebook setiap harinya. Setiap minggu pengguna berbagi lebih dari 8 miliar lembar konten, termasuk update status, foto dan catatan. Ditotal, kira-kira setiap bulan lebih dari 5 milyar foto diupload ke Facebook.
 

Jumlah yang sangat besar ini tentu membutuhkan kapasitas server yang sangat besar pada data center, karena diperlukan untuk  menampung data setiap detiknya akibat beragam kegiatan pengguna melalui account facebook.

Begitulah keunikan dari situs jejaring sosial terbesar ini. Seperti yang kita rasakan saat ini bahwa facebook sangatlah cepat diakses dan minim sekali down, berbeda dengan beberapa tahun lalu ketika awal pengembangannya, facebook terasa agak berat diakses apalagi untuk pengguna Indonesia, tapi hal itu telah berlalu dan saat inilah masa kejayaan facebook. Berikut bisa kita lihat beberapa gambar pada facebook server farm.
 

Ladang server facebook memiliki sistem pendingin canggih dan bisa menyimpan pasokan tenaga listrik. Lihatlah kabel-kabel yang terhubung sebagai saluran lalu-lintas data dari seluruh dunia.

Pusat server dibangun menggunakan replikasi berlapis, yang membuatnya hampir tidak mungkin gagal, bahkan jika sistem di San Fransisco overload.

Server memproses update halaman pengguna secepat mungkin, sehingga komentar atau posting tampil dalam hitungan detik. Menampung 550 juta (dan terus bertambah) pengguna, Maka dari itu membutuhkan kekuatan pusat data yang luar biasa.
