AWS Databases: What are the AWS databases?

AWS offers a wide range of database services for a variety of needs and uses, enabling organizations of all sizes to manage, store and analyze their data efficiently and securely.

Whether for large-scale applications, e-commerce platforms or academic research projects, AWS database services are proving to be invaluable tools.

AWS offers over 15 database services that can satisfy a variety of needs, from relational databases to graph-oriented databases to NoSQL databases.

In this article, we’ll explore some of the database services offered by AWS.

Amazon RDS: versatility

Amazon Relational Database Service (Amazon RDS) is a service that facilitates the configuration, use and scaling of relational databases in the AWS cloud. RDS supports several relational database management systems, such as MySQL, PostgreSQL, MariaDB, Oracle and Microsoft SQL Server.

RDS has some very interesting key features, such as:

Ease of use: Amazon RDS lets users deploy a relational database in just a few clicks.

Scalability: with RDS, you can easily resize computing and storage capacity

Performance: Amazon RDS delivers fast, predictable performance with the ability to deploy high-memory, compute-optimized database instances.

High availability: Amazon RDS offers high-availability options with multi-AZ deployments and read replicas

Security: RDS includes several security features

Amazon Aurora: when compatibility rhymes with performance

Amazon Aurora is a relational database service, combining the performance and availability of high-end commercial databases with the simplicity and cost-effectiveness of open-source databases. Aurora is compatible with MySQL and PostgreSQL.

Here are some of the key features of Amazon Aurora:

Exceptional performance: Amazon Aurora offers up to 5 times the performance of MySQL and 3 times the performance of PostgreSQL

High availability and durability: Aurora automatically replicates data to six separate sites in three AWS availability zones

Automatic scalability: Aurora automatically adjusts storage capacity, from 10 GB to 128 TB, according to need

Advanced security: Aurora offers options for encrypting data at rest and in transit, and for controlling database access using AWS IAM

DynamoDB: performance and scalability

Amazon DynamoDB is a NoSQL database service, designed to deliver low-latency performance for large-scale applications. DynamoDB is ideal for applications requiring fast read and write access, with response times in milliseconds.

Here are the key features and benefits of DynamoDB:

Performance and scale: Can handle more than 10 trillion requests per day and can handle peaks of more than 20 million requests per second.

Flexibility and ease of use: Supports both document and key-value data models.

High availability and durability: Automatically synchronizes data across three availability zones.

Zero administration: DynamoDB eliminates administrative complexity, allowing users to focus on innovating and improving their applications.

Cost-effectiveness: Offers a flexible pricing model.

Rugged security: Offers advanced security features.

DocumentDB: MongoDB specialist

Amazon DocumentDB is a fast, scalable and highly available document database service that makes it easy to store, query and index JSON data. It is designed to run existing MongoDB applications at large scale.

Performance: Offers millisecond read latency with the ability to execute thousands of requests per second.

Scalability : Allows scaling of read capacity up to 15 read replicas for each instance.

Sustainability and availability: Data is replicated six times over three availability zones.

MongoDB compatibility: Compatible with MongoDB, allowing developers to use their existing tools, applications and code without modification.

Simplified management: DocumentDB handles operational tasks such as backups, restoration, patching and fault detection.

Enhanced security: DocumentDB offers advanced security features.

ElastiCache: optimization and acceleration

Amazon ElastiCache is a web service that simplifies the deployment, operation and scaling of an in-memory data store in the AWS cloud. It improves the performance of web applications by enabling rapid retrieval of information stored in memory, thus reducing the time needed to access a traditional database.

High performance: ElastiCache offers microsecond latency for reading and writing operations, enabling applications to access data quickly.

Scalability: ElastiCache allows you to start with a small cache instance and resize it as demand increases, without service interruption.

High availability and durability: With support for multi-zone deployments and replication, ElastiCache minimizes the risk of downtime and ensures data availability.

AWS MemoryDB for Redis: in-memory storage

Amazon MemoryDB for Redis is a fully managed in-memory database service, offering extreme durability and resilience for applications requiring microsecond access to data.

It’s an ideal solution for applications requiring in-memory storage with data persistence, such as real-time applications, recommender systems and user sessions.

Data durability: Stores data synchronously in multiple availability zones, ensuring data durability in the event of a zone failure.

High performance: MemoryDB offers memory access with microsecond response times, optimizing performance for latency-sensitive applications.

Enhanced security: MemoryDB offers advanced security features such as encryption of data at rest and in transit, and resource isolation with Amazon VPC.

Amazone Neptune: graph management

Amazon Neptune is a fully managed graph-oriented database service, optimized for storing and navigating highly connected data. It provides a powerful and reliable way to create and run graph applications, such as social networks, recommendation systems and fraud detection engines.

High performance: Amazon Neptune is designed to deliver high graph query performance.

Scalability and security: Neptune is easily scalable and offers advanced security features.

Graph model compatibility: Supports Property Graph and RDF graph models, and offers APIs compatible with Apache TinkerPop Gremlin and SPARQL.

Efficient Graph Queries: Efficiently execute complex graph queries.

To conclude

In this article, we’ve succinctly covered some of the most popular database services offered by AWS. This demonstrates once again Amazon’s power in cloud computing.
