How It Works

Your Challenge

A customer in the media industry has both MySQL and Redis databases instance deployed on-premises, and wants migrate to Alibaba Cloud in order to take full advantages of running a managed database service that enables elasticity, scalability, security and full database lifecycle management. Given the nature of the industry, a minimized transition time is essential.

Our Solution

  • Alibaba Cloud is committed to offering a seamless database migration experience to you. Data Transmission Service (DTS) allows you to migrate your metadata, full tables (existing data), and incremental data generated during the migration process with zero impact on applications that rely on these databases.

  • After the source database (think of on-premises deployment) and target databases (think of Alibaba Cloud deployment) are synced up, applications can switch to the new databases within seconds. Cross-cloud, cross-platform, and cross-version migration is easier than ever with minimized disruption to business functions.

Data Transmission Service (DTS)

Supports data migration and data synchronization between different data engines.

Your Challenge

Many enterprises are replacing on-premises databases in Internet Data Centers (IDCs) with cloud-native databases. However, the poor compatibility, incomplete migration products and tools, and nonstandard operation process during the migration consumes a lot of time and budget, and causes data inconsistency and incompatibility after the migration.

Our Solution

  • Alibaba Cloud’s Oracle Database Migration solution can help you smoothly migrate Oracle databases in various deployment modes to a public cloud, hybrid cloud, or private cloud. Alibaba Cloud offers the world’s leading cloud-native database technology to help you achieve low costs, high efficiency, auto-scaling, and cloud-native transformation.

  • Prior to the migration, you can use Alibaba Cloud’s Advanced Database & Application Migration (ADAM) to assess the migration feasibility, select appropriate destined databases, determine the migration risks, and estimate the workload, costs, and duration of Oracle database migration.

Your Challenge

A customer in the e-Commerce industry has a business that is growth exponentially, but one or more databases deployed on-premise are experiencing extremely slow performance or even stop responding during peak-time usage, resulting in a large percentage of consumers not being able to complete their transactions. How to revisit the system design once migrated to the cloud and take full advantages of elasticity and full management becomes a challenge when your business scenarios are complex.

Our Solution

  • Through hands-on work with customers, our database architect team, with years of experience accumulated in the e-commerce industry, is well positioned to identify innovative and unique product combinations. The following design was previously recommended to an e-commerce customer and implemented on-demand:

  • 1) Switching to a microservice architecture, allowing different business units to scale on-demand separately;

  • 2) Separating analytical workloads from transactional workloads to maximize system stability during peak-time usage;

  • 3) Adopting ApsaraDB for PolarDB for workload-based elasticity, allowing each microservice to scale up without limits.

Your Challenge

When a database system is deployed on-premises, it can be very time-consuming to manually solve the following authentication related challenges such as weak passwords, firewall issues, and brute-force attacks. The more time your team needs to spend on the such issues, the less bandwidth they have to focus on the mission critical tasks.

Our Solution

  • Security is rooted in the entire database stack of Alibaba Cloud. Specifically, Data Management Service (DMS) is a one-stop solution that provides the following capabilities: authentication control, authorization policy management, monitoring services, performance tuning and database lifecycle management.

  • With full stack access control, DMS allows customers to manage authentications not only at the control plane (CHANGE/DROP/CREATE/REBOOT and other database instance operations), but also at the data plane (SELECT/UPDATE/DELETE/ and other query operations). Your cloud databases are even more secure than physically isolated on-premises databases.

Data Management Service (DMS)

Supports structure management, security auditing, trend analysis, and data tracing.
