Kinerja AWS Lambda: JavaScript vs Python vs Golang

Bahasa apa yang harus digunakan untuk AWS Lambda?

Konten Halaman

Kita dapat menulis fungsi lambda untuk deployment ke AWS dalam beberapa bahasa. Mari kita bandingkan kinerja fungsi (hampir kosong) yang ditulis dalam JavaScript, Python, dan Golang…

TL;DR

Dengan singkat:

Bahasa Durasi Billed Warm-up Durasi Billed Ukuran Memori Memori Maksimal yang Digunakan
Python 197 ms 2 ms 128 MB 32 MB
Python S3 516 ms 35 ms 128 MB 77 MB
JavaScript 2 ms 2 ms 128 MB 63 MB
JavaScript S3 120 ms 72 ms 128 MB 89 MB
Golang 11 ms 1 ms 128 MB 20 MB
Golang S3 30 ms 29 ms 128 MB 38 MB
  • Python memiliki waktu warm-up terlama pada 128GB RAM,
  • JavaScript adalah yang paling lambat secara keseluruhan
  • Golang adalah yang terbaik dari ketiga tersebut tetapi tidak secara signifikan

Opsi menarik adalah mempercepat fungsi lambda Python dengan menambahkan lebih banyak memori, dan sekaligus CPU. Ini hanya akan mengurangi waktu warmup, saya kira. Memanggil ke S3 tidak akan menjadi lebih lambat.

Dalam uji sintetik prime numbers oleh AWS - biaya menjalankan Python lambda sama dengan menggunakan 128MB dan 512MB batas RAM, dan kinerja pengaturan 512MB jauh lebih cepat.

Apa itu AWS SAM

Kami menggunakan SAM untuk menguji berbagai fungsi lambda di sini.

AWS SAM adalah Serverless Application Model.

Proyek AWS SAM mencakup template AWS SAM dan kode fungsi. Template SAM menggambarkan bagaimana cara mendeploy, menjalankan, dan menguji fungsi lambda, izin dan parameter penting lainnya untuk membuat stack CloudFormation.

Untuk menggunakan SAM, kita membutuhkan aws cli dan sam cli.

Menginstal AWS cli

Cara lokal: Install AWS CLI di Reinstall linux doc

Atau di situs aws: https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html

Menginstal SAM cli

Secara dasar - Unduh file zip installer SAM cli dari situs AWS, ekstrak dan instal

wget https://github.com/aws/aws-sam-cli/releases/latest/download/aws-sam-cli-linux-x86_64.zip
unzip aws-sam-cli-linux-x86_64.zip -d sam-installation
sudo ./sam-installation/install

# periksa apakah sam sudah terinstal
sam --version

Bersihkan file installer

rm -rf sam-installation
rm aws-sam-cli-linux-x86_64.zip

Membuat fungsi lambda

Memanggil skrip tiga kali

sam init

dan memilih template hello-world setiap kali, tetapi dengan bahasa yang berbeda, kita membuat 3 aplikasi sam

Fungsi Lambda berbasis Python 3.12

keluaran dari sam init:

    -----------------------
    Generating application:
    -----------------------
    Name: t1-py
    Runtime: python3.12
    Architectures: x86_64
    Dependency Manager: pip

    Output Directory: .
    Configuration file: t1-py/samconfig.toml
    
    Langkah berikutnya dapat ditemukan di file README di t1-py/README.md
        

Perintah yang dapat digunakan berikutnya
=========================
[*] Membuat pipeline: cd t1-py && sam pipeline init --bootstrap
[*] Memvalidasi template SAM: cd t1-py && sam validate
[*] Uji Fungsi di Cloud: cd t1-py && sam sync --stack-name {stack-name} --watch

Fungsi Lambda berbasis JavaScript dan nodejs20.x

keluaran dari sam init:

    Langkah berikutnya dapat ditemukan di file README di t3-go/README.md

Membangun, Uji, Deploy, dan Eksekusi - Fungsi Lambda berbasis Python

uji secara lokal

sam build --use-container

keluaran menunjukkan di akhir:

Perintah yang dapat digunakan berikutnya
=========================
[*] Memvalidasi template SAM: sam validate
[*] Memanggil Fungsi: sam local invoke
[*] Uji Fungsi di Cloud: sam sync --stack-name {{stack-name}} --watch
[*] Deploy: sam deploy --guided

setelah menjalankan tiga kali

sam local invoke

keluaran yang kita lihat:

Baik, setiap panggilan memakan waktu 1/2 detik, dan RAM yang digunakan adalah 128 MB

uji di aws

sam build --use-container
sam deploy --guided

SAM cli akan menanyakan nama stack CloudFormation, lalu konfirmasi, lalu mendeploy fungsi kita ke AWS. Halaman terakhir dari keluaran sam akan terlihat seperti

Lihat di sana kunci HelloWorldApi dengan deskripsi URL endpoint API Gateway untuk stage Prod untuk fungsi Hello World? Ini adalah URL publik kita:

https://wq3w4d41j7.execute-api.ap-southeast-2.amazonaws.com/Prod/hello/  

tapi mari kita mulai dulu listener log kita:

sam logs -n HelloWorldFunction --stack-name "t1-py" --tail

dan kemudian sementara listener log berjalan, panggil di jendela terminal lain:

curl https://wq3w4d41j7.execute-api.ap-southeast-2.amazonaws.com/Prod/hello/
curl https://wq3w4d41j7.execute-api.ap-southeast-2.amazonaws.com/Prod/hello/

Bangun, Uji, Deploy, dan Eksekusi - Fungsi Lambda Berbasis Golang

Pengujian Lokal Golang Lambda

Untuk jelasnya - membuat panggilan tes, bukan menjalankan pengujian unit.

Perintah sam build berada di dalam Makefile. Jadi kita menjalankan:

make

jalankan fungsi tunggal

sam local invoke HelloWorldFunction --event events/event.json
sam local invoke HelloWorldFunction --event events/event.json
sam local invoke HelloWorldFunction --event events/event.json

sam local invoke HelloWorldS3Function --event events/event.json
sam local invoke HelloWorldS3Function --event events/event.json
sam local invoke HelloWorldS3Function --event events/event.json

Opsi 2: sekarang mulai server lokal:

sam local start-api

output:

sekarang di jendela terminal terpisah:

curl http://localhost:3000/hello
curl http://localhost:3000/hello
curl http://localhost:3000/hello

curl http://localhost:3000/hellos3
curl http://localhost:3000/hellos3
curl http://localhost:3000/hellos3

output dari panggilan lokal sederhana ke lambda berbasis golang:

output dari panggilan lokal “s3” ke lambda berbasis golang:

durasi 1ms terlihat bagus, tetapi Memory Size: 128 MB? Mengapa? Harusnya seperti 12MB? Mungkin itu minimum yang mereka punya.

Pengujian AWS Golang Lambda

sam deploy --guided

mulai pendengar log

dan panggil fungsi 3 kali:
