Z1d instances deliver the fastest memory optimized instances that are best utilized for relational database workloads with high per-core licensing costs. X1e and X1 instances are memory optimized for high-performance databases. Hardware Configuration X1e and X1 instances They are powered by the AWS Nitro System and EBS optimized. R5 and R4 Instances are optimized for memory-intensive applications. Hardware Configuration R5 and R4 Instances R6g instances are powered by AWS Graviton2 processors, custom designed by AWS for Arm architecture, with 64-bit Arm Neoverse cores. Hardware Configuration Memory Optimized Database Instances R6G instances The latest generation M5 offers up to 96 vCPUs and 384 GiB of memory, and up to 25 Gbps network bandwidth through enhanced networking. M5 and M4 instances are designed for a wide range of open source and enterprise applications in the cloud that use compute, memory and networking resources in equal parts. Hardware Configuration M5 and M4 instances M6G instances are EBS-optimized by default. They support enhanced networking bandwidths of up to 25 Gbps. M6g instances are powered by Arm-based AWS Graviton2 processors with 64-bit Arm Neoverse cores. These are burstable instances that can withstand sudden bursts in CPU performance beyond a baseline level. They accumulate CPU credits when a workload is operating below the baseline, to be used at times of burstable performance. T3 instances are configured for unlimited mode that allow them to burst beyond the baseline over a 24-hour period at an additional charge which ensures high performance during peak periods. Amazon RDS DB Instance Types General Purpose Database Instances T3 and T2 Instances Each instance type includes a number of sizes allowing your database to scale to meet your workload requirements. They come in different combinations of CPU, memory, storage, and networking capacity. What are the different RDS DB instance classes General purpose and memory optimized instances are designed for flexibility to build the required mix of database resources for relational database applications. Amazon RDS provides a database infrastructure that fully manages the provisioning, scaling, and monitoring of servers for game developers. Mobile and online games that need a database platform with high throughput and high availability. Web and mobile applications that operate at very large scale and need a database with high throughput, massive storage scalability, and high availability.Įcommerce applications that need a flexible, secure, scalable database solution at low cost. It is available for use on the following database engines: Amazon Aurora, PostgreSQL, MySQL, MariaDB, Oracle Database, and Microsoft SQL Server. Amazon Relational Database ServiceĪmazon RDS automates administrative tasks such as hardware provisioning, database setup, patching and backups. In this article we will focus on Amazon RDS DB instances. In an earlier article we covered Amazon Redshift and its pricing. Relational databases are used for ERP, CRM, e-commerce applications.ĪWS resources for relational databases include Amazon RDS and Amazon Redshift. SQL, Structured Query Language, is the primary interface designed to communicate with Relational Databases (RDS) and support referential integrity and data consistency. Relational databases store a collection of data with predefined relationships between them.
