Selain pemicu umum dari Function Compute, seperti tugas terjadwal dan operasi API, Function Compute menyediakan pemicu acara untuk layanan Alibaba Cloud. Pemicu ini memungkinkan integrasi otomatis antar sistem, respons real-time, dan fleksibilitas dalam aplikasi. Pemicu acara untuk layanan Alibaba Cloud dipicu menggunakan EventBridge, yang menyediakan sistem manajemen acara terpusat untuk berbagai layanan Alibaba Cloud. Anda dapat memilih jenis pemicu sesuai kebutuhan bisnis Anda.
Apa itu pemicu acara untuk layanan Alibaba Cloud?
Dalam model berbasis acara, sumber acara menghasilkan acara, fungsi memproses acara, dan pemicu digunakan untuk mengelola sumber acara secara terpusat. EventBridge bukanlah sumber acara tunggal, tetapi pusat acara untuk sumber acara Alibaba Cloud. EventBridge dapat diintegrasikan dengan hampir semua layanan Alibaba Cloud, termasuk komputasi elastis, penyimpanan, basis data, kontainer, big data, observabilitas, dan middleware. Pemicu berbasis EventBridge memungkinkan Anda menggunakan acara Alibaba Cloud sebagai sumber untuk memanggil fungsi. Gambar berikut menunjukkan prosesnya.
Manfaat
Integrasi Otomatis
Setelah EventBridge diintegrasikan dengan Function Compute, sumber pemicu dari EventBridge dan Function Compute disinkronkan. Setelah Anda menambahkan sumber acara di EventBridge, Function Compute secara sinkron memperbarui sumber pemicu. Ini menyederhanakan penggunaan Function Compute.
Skalabilitas
Konfigurasi pemicu asli relatif sederhana. Jika Anda perlu mengimplementasikan logika yang lebih kompleks, seperti menetapkan beberapa kondisi filter awalan dan akhiran file untuk pemicu Object Storage Service (OSS) atau mengaitkan lebih dari 10 pemicu dengan bucket, Anda dapat menggunakan pemicu OSS dari jenis Pemicu Acara untuk Layanan Alibaba Cloud. Untuk informasi lebih lanjut, lihat Ikhtisar Pemicu OSS.
Respons Real-Time dan Keandalan
EventBridge digunakan untuk mengirimkan acara dengan latensi rendah dan throughput tinggi. Ini memastikan bahwa acara dikirimkan ke fungsi tujuan secara tepat waktu dan andal. EventBridge juga menyediakan mekanisme pengulangan acara dan antrian pesan gagal untuk meningkatkan stabilitas dan keandalan sistem.
Skenario sampel
Pemrosesan dan Analisis Data
Pemicu acara untuk layanan Alibaba Cloud dapat digunakan dalam skenario pemrosesan dan analisis data. Misalnya, Anda dapat menentukan bahwa suatu fungsi secara otomatis dipicu untuk melakukan operasi seperti kompresi gambar, konversi format, atau moderasi konten ketika file diunggah ke Object Storage Service.
Manajemen dan Optimasi Sumber Daya
Pemicu acara untuk layanan Alibaba Cloud dapat digunakan dalam skenario manajemen dan optimasi sumber daya. Misalnya, Anda dapat menentukan untuk secara otomatis mengubah sumber daya terkait ketika status instance Elastic Compute Service (ECS) berubah, seperti ketika dimulai, dihentikan, atau di-restart.
