Introduction to Public Cloud Services

Public cloud refers to a cloud based on the standard cloud computing model, in which service providers make resources available to the general public over the Internet. HUAWEI CLOUD is a public cloud, and the following cloud services are required to implement SAP HANA HA.

Service

Description

Virtual Private Cloud (VPC)

VPC enables you to create private, isolated virtual networks. You can configure IP address segments, subnets, and security groups, assign EIPs, and allocate bandwidth in a VPC.

NOTE:

All SAP HANA systems in a suit are deployed in the same VPC.

Image Management Service (IMS)

IMS provides comprehensive image management capabilities. You can select desired images from Marketplace Image to create ECSs in batches.

NOTE:

Currently, the public cloud platform supports the following SAP images:

  • SUSE Linux Enterprise Server (SLES) 12 SP3 for SAP
  • SUSE Linux Enterprise Server (SLES) 12 SP4 for SAP
  • SUSE Linux Enterprise Server (SLES) 12 SP5 for SAP
  • SUSE Linux Enterprise Server (SLES) 15 SP1 for SAP

Elastic Cloud Server (ECS)

ECS provides scalable, on-demand cloud servers for secure, flexible, and efficient application environments, ensuring reliable, uninterrupted services.

NOTE:

Huawei public cloud provides HANA ECSs for running SAP HANA. For more information, see the SAP HANA User Guide.

Elastic Volume Service (EVS)

EVS provides persistent block storage for services such as ECS and Bare Metal Server (BMS). With advanced data redundancy and cache acceleration capabilities, EVS offers high availability and durability with an extremely low latency. You need to perform operations such as initializing an EVS disk and creating a file system.

NOTE:

For details about the EVS specifications in the SAP HANA scenario, see the SAP HANA User Guide.

(Optional) Scalable File Service (SFS)

SFS provides completely hosted sharable file storage for ECSs. Compatible with the Network File System protocol, SFS is expandable to petabytes, features high performance, and seamlessly handles data-intensive and bandwidth-intensive applications.

NOTE:

The shared and backup volumes can be provided by SFS. For details, see the SAP HANA User Guide.

Volume Backup Service (VBS)

Volume Backup Service (VBS) provides online backup for EVS disks and allows data restoration from backups, offering protection against virus attacks and software and hardware faults.

Object Storage Service (OBS)

OBS is a stable, secure, efficient, and easy-to-use cloud storage service. With Representational State Transfer Application Programming Interfaces (REST APIs), OBS is able to store unstructured data of any amount and form at 99.999999999% reliability (11 nines).
