ApsaraDB for Redis is a database service that is compatible with native Redis protocols. It supports a hybrid of memory and hard disks for data persistence. ApsaraDB for Redis provides a highly available hot standby architecture and can scale to meet requirements for high-performance and low-latency read/write operations.
ApsaraDB for Redis supports multiple architectures, persistent data storage, high availability, auto-scaling, and intelligent operations and maintenance.
The system synchronizes data between the master node and replica node in real-time. If the master node fails, the system automatically fails over to the replica node and restores services within a few seconds. The replica node takes over services. The master-replica architecture ensures the high availability of system services.
Cluster instances run in a distributed architecture. Each node uses a high-availability master-replica structure to automatically perform the failover and disaster recovery. Multiple types of cluster instances apply to various businesses. You can scale the database to improve performance as needed.
Read/write splitting instances consist of proxy servers, master-replica nodes, and read replicas. Read/write splitting instances provide high availability (HA) and high performance. Multiple specifications are available. The read/write splitting architecture allows a large number of concurrent requests to read hot data from reading replicas. This mechanism can reduce the load on the master node and minimize operation and maintenance costs.
Based on the hybrid storage of memory and hard disks, ApsaraDB for Redis provides high-speed data read/write capability and enables data persistence.
The system automatically replicates data every day and provides a powerful disaster recovery solution. You can restore data in case of accidental data operations to minimize your business losses.
A Virtual Private Cloud (VPC) network isolates network transmission at the transport layer.
Anti-DDoS monitors and protects against Distributed-Denial-of-Service (DDoS) attacks.
The system supports more than 1,000 IP whitelists configured to control access risks from requests.
Password authentication ensures secure and reliable access.
Alibaba Cloud has performed in-depth engine optimization for the Redis source code to prevent running out of memory, fix security vulnerabilities, and protect your business.
Standard and cluster instances support the master-replica structure. They can prevent service interruptions caused by a single point of failure (SPOF).
The system automatically detects hardware failures. In the case of failures, the system performs the failover operation and restores services within a few seconds.
Instance-level resource isolation: ApsaraDB for Redis isolates resources among different instances. A failure on an instance does not affect other instances. This improves the service stability. Instance-level resource isolation is a better measure to ensure the stability of individual services.
ApsaraDB for Redis supports multiple types of memory. You can upgrade the memory based on your needs.
The cluster architecture supports the auto-scaling of the storage space and throughput performance of the database system. This can eliminate the performance bottlenecks caused by large amounts of data and high-QPS requirements. Therefore, you can easily handle millions of reading and write requests per second.
This platform provides real-time monitoring information about the CPU usage, connections, and disk utilization, and generates alerts. This allows you to learn about the up-to-date instance status.
This platform allows you to perform frequent and high-risk operations, such as cloning, backup, and data restoration with one click.
The specialized data management service (DMS) platform supports visual data management. This improves the efficiency of comprehensive research and development (R&D) and operations and maintenance (O&M) efforts.
ApsaraDB for Redis supports automatic upgrades to fix vulnerabilities. This way, you do not have to manage each kernel version. Parameter settings are optimized to maximize the utilization of system resources.
ApsaraDB for Redis is an automated and scalable tool for developers to manage data storage shared across multiple processes, applications or servers.
As a Redis protocol compatible tool, ApsaraDB for Redis offers exceptional read-write capabilities and ensures data persistence by using memory and hard disk storage. ApsaraDB for Redis provides data read-write capabilities at high speed by retrieving data from in-memory caches and ensures data persistence by using both memory and hard disk storage mode.
ApsaraDB for Redis supports advanced data structures such as leaderboard, counting, session, and tracking, which are not readily achievable through ordinary databases.
Alibaba Cloud ApsaraDB for Redis hybrid storage instances represents a proprietary database system solution that is fully compatible with the Redis protocol and highly compatible with Redis commands and related features. These hybrid storage instances support storing full data on a disk rather than in the memory and caching hot data in memory, which strikes a balance between access performance and storage costs.
Redis is an open-source in-memory database used by companies around the world—for everything from caching to queuing. Because of its speed and ease of use, Redis is a personal favorite solution of mine for dealing with large key-value datasets.
In the past, I've used Redis to speed up costly ranking queries that were ill-suited to a more traditional relational database. I also often use it to manage auto-expiring caches and FI/FO queue systems within many of the projects I find myself working on.
In this post, I demonstrate how to run Redis on Alibaba Cloud using the ApsaraDB service for high-performance database applications.
