Oracle cloud shell

oracle cloud 서버에 접속하기 위해 cloud shell에 접속환경을 만들었다.

ssh key 생성

아래와 같이 private key, public key 생성

yongsub_yu@cloudshell:~ (ap-seoul-1)$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/home/yongsub_yu/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/yongsub_yu/.ssh/id_rsa.
Your public key has been saved in /home/yongsub_yu/.ssh/id_rsa.pub.
The key fingerprint is:
The key's randomart image is:
+---[RSA 2048]----+
|      .o   .+    |
|     .. = +=o.  o|

Oracle cloud free tier vm benchmark

Oracle cloud free tier Ampere Arm A1 를 설치하고 기존 E2.1.Micro 머신과 성능면에서 어떤 차이가 있는지 테스트 해보았다.

생성한 인스턴스는 3개이다.

E2 머신은 2개까지 생성할 수 있으며 각각 1 OCPU, 1GB MEM 이다.

A1 머신은 arm 4 OCPU, 24GB MEM이다.

그리고 스토리지는 200GB까지 제공된다.

E2.1.Micro 2*50GB, A1.Flex 100GB

sysbench 테스트 결과

왼쪽 A1.Flex(threads=4), 오른쪽 E2.1.Micro(threads=2)

CPU Test
Memory Test
Fileio Test

geekbench 테스트 결과

A1.Flex
E2.1.Micro
Compare : A1.Flex vs E2.1.Micro
