Today, real-time interactions and accurate data streaming with low latency are the foregrounds of web applications. Poor performance on account of loading times or failure to handle concurrent requests from millions of active online users interrupt business operations and severely hamper the overall user experience. Stakes are much higher in several big data scenarios, such as e-commerce, gaming, the internet of things (IoT), finance, and many more. Such business scenarios demand real-time data processing, storage, and processing in large volumes and at high speed.
In-memory data stores such as Redis, play a crucial role to rescue businesses from such situations. Redis' flexible design, simple commands, and the ability to reduce latency effectively boost the performance of modern applications.
Let's take a closer look at how Redis helps businesses optimize operations and improve performance.
Remote Dictionary Server (Redis) is an open-source, in-memory data store that serves as a database, cache or a message broker. Redis is the go-to solution for several real-time applications that demand high throughput and low latency to deliver sub-millisecond query response times.
Redis provides the following functionalities to support businesses in fixing an array of data processing challenges.
Redis completely stores data in RAM to facilitate instantaneous access to data while executing read and write requests. For example, when a user logs into a specific web application, Redis allows in-memory storage of user attributes to eliminate the need to query the database every time the application needs the user information.
Against other schema-less NoSQL databases, Redis is much faster. High-speed performance is at the core of Redis' design. It optimizes data structures to deliver high performance and compiles data efficiently while keeping overheads minimum leveraging ANSI C.
Redis employs the key-value model to store and retrieve data. Key-based access quickens data access and eliminates the need to design structured data tables beforehand which ultimately helps improve the response times for superior customer experience.
Since Redis is binary-safe, it supports every possible data form and size. It stores a wide range of data from binary to text. It also allows storing and managing data shared across several processes, applications or servers. Its strong API support streamlines and simplifies cross-platform storage.
Some scenarios require the cache to persist data to long-lasting storage to ensure faster recovery following a shutdown. Redis provides two options to persist data - employing snapshots or using an append-only file (AOF). Snapshots help create a copy of the cache which is saved to the disk simultaneously whereas, with AOF, every alteration made to the in-memory dataset is written to the disk.
Alibaba Cloud's ApsaraDB for Redis is a key-value cloud database service that is compatible with the Redis protocol and supports most of the Redis commands. It provides in-memory caching and high-speed access to applications hosted on the cloud. Additionally, it supports the hybrid storage of memory and hard disks to ensure data persistence.
ApsaraDB for Redis is ideal for scenarios that demand high read/write performance or flexible configuration changes. It is a comprehensive solution that effectively supports multiple data types, including strings, sets, sorted sets, lists, and hash tables. Furthermore, it supports advanced data structures, including counting, session, leaderboard, and tracking, which are not feasible via ordinary databases.
ApsaraDB for Redis also helps cater to business scenarios demanding advanced functionalities, such as transactions, message subscription, and publishing.
Let's take a quick look at how ApsaraDB for Redis is enabling growth for modern businesses.
ApsaraDB for Redis offers single-click storage expansion in real-time. Businesses usually leverage the management console to adjust the storage capacity of instances according to their requirements. Online resizing ensures that business operations do not stop or hamper business.
Alibaba Cloud's Redis service incorporates a high availability failover system. Hence, whenever the system detects an exception on the master node, it instantly switches over to the slave node to assure high service availability. This mechanism helps to overcome several service exceptions such as CPU and disk I/O faults.
ApsaraDB for Redis deploys easily and scales on-demand according to the business requirements. Businesses only pay for the resources in use.. Moreover, with strong online support from Alibaba Cloud's professional technical team, enterprises do not require dedicated resources to monitor and manage ApsaraDB for Redis instances, cutting OPEX drastically.
Alibaba Cloud ApsaraDB for Redis is a reliable service that helps businesses keep persistent data storage by using both memory and hard disk storage mode. It also offers master and slave dual nodes to ensure consistent backup.
In addition to persistent data storage, ApsaraDB for Redis supports password authentication to ensure secure and reliable access. It also provides automatic backup functionality, thereby allowing teams to align the backup cycle as per their process requirements.
