The cloud migration solution integrates migration processes, methods, tools, and professional teams to help you easily migrate your current workloads to HUAWEI CLOUD.
SOLUTION ADVANTAGES
BUSINESS CHALLENGES
Complex Service Scenarios
Complex IT architectures and a variety of hardware devices; various middleware and versions; complex customer service system correlation.
Long Service Downtime
Real-time services and service continuity require increasingly short downtime windows. Comprehensive migration plans and proper migration paths are key factors in performing successful migrations and preventing them from adversely affecting services.
Weak Data Consistency
Zero service data loss is a prerequisite for migrations. As the quantity of data grows significantly, the core objective for any migration solution is to ensure data consistency by effectively identifying and continuously synchronizing incremental data.
Long Migration Duration
Large quantities of service migration data; suboptimal utilization of transmission bandwidth; lack of tool automation; inefficient manual deployment.
TYPICAL SCENARIOS
Scale compute resources up and down to ensure your services remain tuned to in-the-moment requirements.
Elastic load balancing
ELB automatically expands load distribution capabilities based on the traffic.
Dynamic expansion
ECS and RDS provided by HUAWEI CLOUD can be dynamically extended based on preset scaling policies to cope with service peaks arising from large-scale promotion and flash-sale events, thereby ensuring service stability during the high-access periods.
Data Replication Service (DRS) is a cloud service for migrating and synchronizing databases. It simplifies data transmission processes and reduces transmission costs.
Live Database Migrations
Migrates databases without interrupting services, minimizing any adverse impact on services caused by database breakdowns during migrations.
Multiple Database Engines
Migrates existing MySQL to RDS for MySQL. Migrates existing Microsoft SQL Server to RDS for SQL Server.
Multiple Network Scenarios
Transmits data using a Virtual Private Network (VPN) and the Virtual Private Cloud (VPC) network environment on HUAWEI CLOUD.
Multiple Auxiliary Migration Functions
Provides auxiliary functions such as the ability to monitor migration tasks or to compare data consistency.
Object Storage Migration Service (OMS) is a cloud service for migrating and synchronizing object storage. It migrates object storage efficiently, conveniently, and securely, reducing difficulties and costs associated with data migrations.
Support for Public Clouds from Mainstream Cloud Vendors
Supports data migrations from object storage services on other public clouds to Object Storage Service (OBS) on HUAWEI CLOUD.
Concurrent Migrations
Supports multiple concurrent tasks and migrations of tens of millions of files, improving migration efficiency.
No Need to Retransmit Data After a Network Interruption
If a network interruption occurs during data transmission, you can manually restart the transmission of the remaining data.
Secure Transmission and Storage
Data can be encrypted using HTTPS to ensure its security during transmission. For additional security, data migrated to OBS on HUAWEI CLOUD can be encrypted with server-side encryption using Key Management Service (SSE-KMS).
CDM enables batch data migration among homogeneous and heterogeneous data sources. It is especially suitable for migrating on-premises data or data on third-party clouds to HUAWEI CLOUD EI big data services.
Support for Nearly 20 Types of Data Sources
Data sources, for example, self-built on-premises file systems and the file systems on public clouds (such as OBS, NAS, FTP, and SFTP), relational databases (such as MySQL, PostgreSQL, Oracle, SQL Server, and Db2), DWS, and NoSQL databases (such as Redis and MongoDB), are supported.
Data Migrations Between Heterogeneous Data Sources
Data migrations between different types of data sources, for example, MySQL to Elasticsearch, are supported. You only need to consider data without caring about storage system differences.
Support for Extract, Transform, and Load (ETL)
During data migrations, a wide range of field-level data conversion functions, for example, sensitive information deletions, character string changes, and date format conversion, are supported..
Ease of Use
The wizard-based migration configuration interface provides out-of-the-box usability.
Scale compute resources up and down to ensure your services remain tuned to in-the-moment requirements.
Elastic load balancing
ELB automatically expands load distribution capabilities based on the traffic.
Dynamic expansion
ECS and RDS provided by HUAWEI CLOUD can be dynamically extended based on preset scaling policies to cope with service peaks arising from large-scale promotion and flash-sale events, thereby ensuring service stability during the high-access periods.
MIGRATION PROCESS
Phase 1: Evaluation and Research
Collect service application information on the live network, check on-premises resources, streamline business processes and mutually-dependent relationships, and schedule data migration to HUAWEI CLOUD.
Phase 2: Planning and Designing
Plan migration policies, determine the product portfolio and migration schemes, and formulate a comprehensive plan for migrating services to the cloud based on your business goals and vision.
Phase 3: Migration Implementation
HUAWEI CLOUD provides multiple powerful and flexible migration tools. It combines extensive industry migration experience with qualified partner plans to help you migrate your services simply and efficiently, with minimal adverse impact on services.
Phase 4: Optimization
Use well-proven practices to transform the applications migrated to the cloud, monitor and optimize their configuration, and improve security, performance, and reliability, meeting customersexpectations of return on investment (ROI).
