![]() Replication across three Availability Zones.Īmazon DynamoDB is a fast and flexible non-relational database service for all applications that need consistent, single-digit millisecond latency at any scale.Automatically scales up to 64 TB per database instance.A distributed, fault-tolerant, self-healing storage system.Up to 3X faster than standard PostgreSQL databases.Up to 5X faster than standard MySQL databases.Meet Amazon AuroraĪmazon Aurora is a MySQL and PostgreSQL-compatible relational database for any enterprise application that can use a relational database.Īmazon Aurora offers a broad array of features. You can use the AWS Database Migration Service to easily migrate or replicate your existing databases to Amazon RDS. Meet Amazon Relational Database Service (Amazon RDS)Īmazon RDS is available on several database instance types-optimized for memory, performance, or input/output (I/O)-and provides you with six familiar database engines to choose from. Key-value databases are commonly used for Internet-scale applications, real-time bidding, shopping carts, and customer preferences. NoSQL databases scale horizontally by increasing servers. Each row doesn’t have to contain data for each column.ĭata in NoSQL databases is queried by focusing on collections of documents. NoSQL schemas are dynamic, and information can be added rapidly. NoSQL databases store data using one of many storage models, including key-value pairs, documents, and graphs. Relational databases are commonly used for traditional applications, ERP, CRM, and ecommerce. SQL databases scale vertically by increasing hardware power. You can amend schemas if the database is altered entirely and taken offline.ĭata is queried using structure query language (SQL), which can allow for complex queries. An SQL database schema is fixed: columns must be locked before data entry. Rows contain all the information about one entry, and columns are the attributes that separate the data points. SQL databases store data in rows and columns like a spreadsheet. The most common types of databases are relational (SQL) and key-value or non-relational (NoSQL). Benefit from the high availability, reliability, and security that fully managed AWS database services offer.Ĭhoose from Relational and Key-Value Databases.Stop worrying about server provisioning, patching, setup, configuration, backups, or recovery of your database.Pay as little as 1/10th the cost of commercial databases.Start small and scale as your applications grow.Pick the best database to solve specific problems.Although you can host database software on Amazon EC2, AWS offers a variety of purpose-built database services that are easy to set up, manage, and maintain.ĪWS Database services provide several advantages. Customize Your Database with AWS Database Servicesĭatabases allow you to store, manage, and query structured data. With AWS database services, you can support your growth while maintaining flexibility by only paying for what you use. To keep up with the demand you need a scalable infrastructure that is easy to administer and is cost-effective. Imagine your company has grown from a small startup to a large-scale organization with many product offerings.
