Oracle云:全新的、更高效的优势
Oracle云是一个全新的、更高效的云计算平台,它提供了一系列解决方案,能够满足不同的业务需求,包括基于云的数据库、应用程序、计算机、存储和网络服务等。
Oracle云的主要优势包括:
一、强大的安全性
Oracle云采用了最先进的安全技术,包括多重身份验证、数据加密、网络安全等。此外,Oracle云还支持网络隔离,确保客户数据的完全隔离。
代码示例:
# 多重身份验证
import oci
config = { "user": "myuser",
"key_file": "/path/to/my/key_file", "fingerprint": "mykeyfingerprint",
"tenancy": "mytenancy", "region": "us-phoenix-1"
}
identity = oci.identity.IdentityClient(config)user = identity.get_user(config["user"]).data
print(user)
# 数据加密
import cx_Oracle
conn = cx_Oracle.connect( "username/password@oracle_cloud_db",
encoding="UTF-8", nencoding="UTF-8")
cursor = conn.cursor()
cursor.execute(""" SELECT * FROM my_table
""")result = cursor.fetchall()
print(result)cursor.close()
conn.close()
二、高性能
Oracle云采用了高速网络和云计算技术,确保了超高的性能水平。它支持高可用性、自动扩展和灾难恢复等功能,可以自动调整计算机和存储资源,确保始终提供最佳的性能。
代码示例:
# 高可用性
import oci
config = { "user": "myuser",
"key_file": "/path/to/my/key_file", "fingerprint": "mykeyfingerprint",
"tenancy": "mytenancy", "region": "us-phoenix-1"
}
compute_client = oci.core.ComputeClient(config)
# 启动虚拟机launch_instance_detls = oci.core.models.LaunchInstanceDetls()
launch_instance_detls.display_name = "MyInstance"launch_instance_detls.avlability_domn = "MyAvlabilityDomn"
launch_instance_detls.compartment_id = "MyCompartmentId"launch_instance_detls.image_id = "MyImageId"
instance = compute_client.launch_instance(
launch_instance_detls).data
print(instance)
# 停止虚拟机compute_client.instance_action(
instance.id, "STOP"
)
# 启动虚拟机compute_client.instance_action(
instance.id, "START"
)
# 自动扩展
import oci
config = { "user": "myuser",
"key_file": "/path/to/my/key_file", "fingerprint": "mykeyfingerprint",
"tenancy": "mytenancy", "region": "us-phoenix-1"
}
autoscaling_client = oci.autoscaling.AutoScalingClient(config)
# 创建自动扩展配置create_auto_scaling_configuration_detls = oci.autoscaling.models.CreateAutoScalingConfigurationDetls()
create_auto_scaling_configuration_detls.display_name = "MyAutoScalingConfiguration"create_auto_scaling_configuration_detls.compartment_id = "MyCompartmentId"
create_auto_scaling_configuration_detls.policy = "time"create_auto_scaling_configuration_detls.time_based_scale_out_cooldown_in_seconds = 60
create_auto_scaling_configuration_detls.time_based_scale_in_cooldown_in_seconds = 120create_auto_scaling_configuration_detls.predictive_scale_out_cooldown_in_seconds = 180
create_auto_scaling_configuration_detls.predictive_scale_in_cooldown_in_seconds = 300create_auto_scaling_configuration_detls.predictive_unit.lower_boundary = 1
create_auto_scaling_configuration_detls.predictive_unit.upper_boundary = 10
auto_scaling_configuration = autoscaling_client.create_auto_scaling_configuration( create_auto_scaling_configuration_detls
).dataprint(auto_scaling_configuration)
# 创建自动扩展策略
create_auto_scaling_policy_detls = oci.autoscaling.models.CreateAutoScalingPolicyDetls()create_auto_scaling_policy_detls.display_name = "MyAutoScalingPolicy"
create_auto_scaling_policy_detls.policy_type = "threshold"create_auto_scaling_policy_detls.threshold.policy_exit_timeout_in_seconds = 300
create_auto_scaling_policy_detls.threshold.threshold_count = 80create_auto_scaling_policy_detls.threshold.action = "scale_out"
auto_scaling_policy = autoscaling_client.create_auto_scaling_policy(
auto_scaling_configuration.id, create_auto_scaling_policy_detls).data
print(auto_scaling_policy)
三、灵活的部署
Oracle云支持公共云、私有云和混合云等云部署模式,可以根据客户的需求进行灵活的部署。
代码示例:
# 部署到公共云
import oci
config = { "user": "myuser",
"key_file": "/path/to/my/key_file", "fingerprint": "mykeyfingerprint",
"tenancy": "mytenancy", "region": "us-phoenix-1"
}
identity = oci.identity.IdentityClient(config)user = identity.get_user(config["user"]).data
print(user)
# 部署到私有云
import oci
config = { "user": "myuser",
"key_file": "/path/to/my/key_file", "fingerprint": "mykeyfingerprint",
"tenancy": "mytenancy", "region": "my-private-region",
"endpoint": "https://my-private-endpoint.oraclecloud.com"}
identity = oci.identity.IdentityClient(config)
user = identity.get_user(config["user"]).data
print(user)
# 部署到混合云
import oci
config = { "user": "myuser",
"key_file": "/path/to/my/key_file", "fingerprint": "mykeyfingerprint",
"tenancy": "mytenancy", "region": "us-phoenix-1",
"endpoint": "https://my-private-endpoint.oraclecloud.com"}
identity = oci.identity.IdentityClient(config)
user = identity.get_user(config["user"]).data
print(user)
