Common Tasks

After you perform basic operations, such as create a bucket, upload and download an object, you can experience common OBS tasks.

**Table 1** Common tasks
Task		Description
Data security	Enterprise Data Access Control	After subscribing to OBS, enterprises can control access to their data: Grant different departments with only required permissions to isolate access to the enterprise data. Grant permissions to users from a different department or project to download the shared data but not to write or delete the shared data. Grant each department with required IAM user permissions and use bucket policies to grant the IAM users independent permissions on resources. Add external buckets on OBS Browser+ to isolate bucket resources between departments.
Data migration	Migrating Local Data to OBS	Huawei Cloud offers diverse solutions for migrating data from on-premises storage servers to OBS in a cost-effective, secure, and efficient way. You can choose a migration solution based on your data volume, time arrangement, and budget.
Data migration	Migrating Data from Third-Party Cloud Service Vendors to OBS	With Huawei Cloud Object Storage Migration Service (OMS), you can easily migrate data from a third-party cloud vendor to OBS by only configuring connection parameters and migration tasks on OBS Console.
Data backup	Using Backup Software to Back Up Local Data to OBS	Third-party backup software, such as Commvault and AnyBackup Cloud, can connect to OBS for data backup. You can customize policies for secure and efficient backups.
Data access	Accessing OBS from an ECS over the Intranet	You can read, back up, and archive data on OBS from your ECS over an intranet.
	Accessing OBS Through an NGINX Reverse Proxy	For security purposes, some enterprises need to configure a blacklist or whitelist for external addresses, so a fixed IP address is required for accessing OBS. However, Huawei Cloud DNS always resolves the bucket's access domain name to different IP addresses for secure access. To address this problem, you can set up an NGINX reverse proxy server on an ECS to allow users to access OBS with a fixed IP address.
	Using a User-Defined Domain Name to Host a Static Website	If a company has a large number of static websites but does not want to set up servers, the company can host these websites in an OBS bucket, so that users can access the websites using the domain name bound to the OBS bucket.
Data transmission	Using the PostObject API to Upload Data from a Web Client to OBS	PostObject API can directly upload files from a web client to OBS, which is called browser-based upload. With this method, you do not have to upload data to the app server before uploading data to OBS. This makes data transmission faster and does not impose pressure on the server. Additionally, direct transmission with a signature returned by the server is more secure.
	Uploading Data from Mobile Apps to OBS	OBS is widely used as the storage for Android phones and iOS apps. To protect application data from leakage and unauthorized access, you are advised to use a temporary security credential or a presigned URL to upload data to OBS.
	Uploading Data from Mini Programs to OBS	Mini programs are now popular in a variety of scenarios. You can upload data to OBS from a mini program.
Data processing	CDN for Download Acceleration	This solution automatically caches data stored in OBS on demand to CDN points of presence (PoPs) in different regions, accelerating the access to and download of static resources.
