Public Cloud – Flexible Engine

Physical storage media to transmit a large amount of data to Flexible Engine

[Features – Storage]

Data Express Service (DES) is a TB- or PB-scale data transmission service

It uses physical storage media (such as Teleport) to transmit a large amount of data to Flexible Engine. DES provides a data transmission speed at 1000 Mbit/s, 10 times faster than high-speed Internet transmission but at only one fifth of the cost. It helps to address issues facing massive data transmission such as high network costs and long transmission time. DES does not occupy your public network bandwidth or compete with main services for bandwidth resources.

Teleport suits TB- and PB-scale data migration. Currently, the capacity of a single Teleport is 60 TB. The Teleport is mailed to you by a Flexible Engine data center (DC).

DES saves your effort and money in writing code or buying any hardware for data transmission. You only need to create service orders on DES Console and use Teleports as the storage media to transmit data to Flexible Engine securely, quickly, and efficiently.

Safer, faster, and more efficient, has great advantages over conventional personal storage and network data transmission

Efficient transmission of massive data to the cloud

In DES, after the migration medium storing your data is received by the Flexible Engine DC, the administrator mounts the device to the server. Then the successful verification with access keys (AK/SK) input by you triggers the data upload over high speed network. DES greatly improves the data transmission rate, shortens the time for massive data transmission to the cloud, and reduces the cost.

Robust data security

  • Teleport-based DES provides military class enclosure, GPS tracking, restricted area unlock, as well as deduplication and compression. These measures ensure secure transmission.
  • Signature files are generated for service orders. A signature file is the unique identifier for matching a DES order with a Teleport, which prevents mis-operations caused by manual matching.
  • Before the data is uploaded to OBS, you need to enter the access keys (AK/SK) to trigger data upload. When the data is uploaded to OBS, SSL encryption is supported. In addition, OBS uses access keys (AK/SK) to authenticate the your access and controls the access to buckets and objects in various ways, such as ACL and bucket policies. These measures ensure the security of data upload and access.
  • Data transmitted by DES is stored on OBS. It is stored in shards and then randomly distributed on different disks. For this reason, even if some disks are stolen in the DC, your data cannot be completely restored with those lost disks.

Lower maintenance costs

After you store massive data in OBS buckets via DES, no maintenance personnel is required to maintain storage devices, because device maintenance and data management are processed by Flexible Engine DCs.

Simple configuration

Teleport is a plug-and-play device with power cables, 10GE optical fibers, and 10GE network cables. Simply by configuring IP addresses, you can start data replication within one minute.

DES has the following functions

Security guarantee

DES has a comprehensive security mechanism to protect your data from being maliciously accessed and tampered with.

  • Security assurance of the migration medium: Teleport-based DES provides Teleport which is dust- and water-proof and resistant to vibration and crush. Teleport has safety lock, alarm recording, GPS tracking, and restricted area unlock functions.
  • Security assurance during data transmission: After the migration medium storing your data is received by the Flexible Engine DC, the administrator mounts the Teleport to the server. Then an SMS message is sent to notify you of inputting the access keys (AK/SK). After the key authentication is successful, data upload is triggered. In this manner, the administrative personnel have no access to your keys or data, ensuring data security during transmission.

Transmission rate

One of the important features of DES is to provide a high-speed transmission rate to solve the problem of long data transmission time. The upload speed of local data is severely limited by your network bandwidth. DES stores your data in the migration medium and transports the data to a Flexible Engine DC to solve the problem of limited network bandwidth. However, the data upload rate of Teleport is also affected by the type and size of the data file. The transmission rate of common files can reach 500 MB/s, and the transmission rate of massive small files and ultra-large files can reach 200 MB/s.

Service status tracking

For scenarios, such as vehicle simulation, gene sequencing, machine learning, etc, it is recommended to use Ultra-High I/O DSS to meet the application requirements for high I/O and high throughput. The DSS can also support the physically isolated storage resource pool to high secure the tenant’s data.

Mis-operation prevention

A signature file is the unique identifier for matching a DES order with a migration medium. DES system identifies a signature file and automatically matches the migration medium with a service order to prevent mis-operations.

After a service order is successfully placed, the system generates a unique signature file. You need to save the signature file to the Teleport root directory, and mail the device to the Flexible Engine DC. After the administrator receives and mounts the Teleport to the server, the system automatically identifies the service order that matches the signature file information on the Teleport. After the signature file matches the service order, the system triggers data upload based on the access keys (AK/SK) entered by you. Mis-operations are therefore prevented, because there is no manual intervention during the data upload.

Report generation

You can obtain a report about your DES order details. After data uploading is complete, a report is generated for you to confirm that all data is transmitted.
