Which database service can scale to higher database sizes?

DB instances for Amazon RDS for MySQL, MariaDB, PostgreSQL, Oracle, and Microsoft SQL Server use Amazon Elastic Block Store (Amazon EBS) volumes for database and log storage. In some cases, your database workload might not be able to achieve 100 percent of the IOPS that you have provisioned. For more information, see For more information about instance storage pricing, see Amazon RDS pricing . Amazon RDS storage types Amazon RDS provides three storage types: General Purpose SSD (also known as gp2 and gp3), Provisioned IOPS SSD (also known as io1), and magnetic (also known as standard). They differ in performance characteristics and price, which means that you can tailor your storage performance and cost to the needs of your database workload. You can create MySQL, MariaDB, Oracle, and PostgreSQL RDS DB instances with up to 64 tebibytes (TiB) of storage. You can create SQL Server RDS DB instances with up to 16 TiB of storage. For this amount of storage, use the Provisioned IOPS SSD and General Purpose SSD storage types. The following list briefly describes the three storage types: • General Purpose SSD – General Purpose SSD volumes offer cost-effective storage that is ideal for a broad range of workloads running on medium-sized DB instances. General Purpose storage is best suited for development and testing environments. For more information about General Purpose SSD storage, including the storage size ranges, see • Provisioned IOPS SSD – Provisioned IOPS storage is designe...

• • • • • This post was reviewed and updated May,2022. As a managed service, In this post, we look into how we can vertically and horizontally scale your RDS instance. Vertical scaling refers to adding more capacity on your storage and compute of your current RDS instance. In contrast, horizontal scaling refers to adding additional RDS instances for reads and writes. Vertical scaling Vertical scaling is the most straightforward approach to adding more capacity in your database. Vertical scaling is suitable if you can’t change your application and database connectivity configuration. You can vertically scale up your RDS instance with a click of a button. Several The following are some things to consider when scaling up an RDS instance: • Before you scale, make sure you have the correct licensing in place for your commercial engine such as Oracle, especially if you Bring Your Own License (BYOL). You can use License Manager to centrally track usage of your Oracle database licenses based on your license agreement terms. • Database instance class support varies by database engine and AWS Region. • Determine when you want to apply the change. You can apply the change immediately or during the maintenance window specified for the instance. • Storage and instance type are decoupled. Also, modifying your storage doesn’t incur any downtime. If your workload is predictable, you can separately modify your DB instance to increase the allocated storage space or improve performance by ch...

In this article This article describes resource consumption models of Synapse SQL. Serverless SQL pool Serverless SQL pool is a pay per query service that doesn't require you to pick the right size. The system automatically adjusts based on your requirements, freeing you up from managing your infrastructure and picking the right size for your solution. Dedicated SQL pool - Data Warehouse Units (DWUs) and compute Data Warehouse Units (cDWUs) Recommendations on choosing the ideal number of data warehouse units (DWUs) to optimize price and performance, and how to change the number of units. Data Warehouse Units A Synapse SQL pool represents a collection of analytic resources that are being provisioned. Analytic resources are defined as a combination of CPU, memory, and IO. These three resources are bundled into units of compute scale called Data Warehouse Units (DWUs). A DWU represents an abstract, normalized measure of compute resources and performance. A change to your service level alters the number of DWUs that are available to the system. In turn, this change adjusts the performance and cost of your system. For higher performance, you can increase the number of data warehouse units. For less performance, reduce data warehouse units. Storage and compute costs are billed separately, so changing data warehouse units does not affect storage costs. Performance for data warehouse units is based on these data warehouse workload metrics: • How fast a standard data warehousing qu...

Storage is the first-factor we choose while designing an application. Every application needs a reliable storage structure for the proper function of the software. The diversity of data may be as to be streamed or store the account-related data. It is a point that Dragonite has more than 2600 CP, which they need to manage. The type of data storage can be different depending upon what the application is going to process. Google comes with a variety of options to store, analyze, and process this data. We know that google cloud previously has persistent disks to store huge data but to meet the customer’s new requirements they included some core storage options into their cloud infrastructure. Let me drive you to the options they offer and you can pick from below that satisfies your applications need – • Cloud Storage : Google Storage is a service offered by Google for storing the data objects into Google Cloud. A data object can be termed as an immutable entity that consists of data of any file irrespective of the format. It is best for the applications containing structured data objects, for example, large media files and images. Unstructured type data objects are also supported which is used for backups. • Cloud Spanner : Google Spanner is the first of its kind data storage option, which supports relational database structure with a non-relational horizontal scale. It is highly scalable which consistent SQL support and is available at a high rate. It is best for application...

In this article This article describes how to scale the compute and storage resources available for an Azure SQL Database in the provisioned compute tier. Alternatively, the After initially picking the number of vCores or DTUs, you can scale a single database up or down dynamically based on actual experience using: • • • • • Important Under some circumstances, you may need to shrink a database to reclaim unused space. For more information, see Impact Changing the service tier or compute size of mainly involves the service performing the following steps: • Create a new compute instance for the database. A new compute instance is created with the requested service tier and compute size. For some combinations of service tier and compute size changes, a replica of the database must be created in the new compute instance, which involves copying data and can strongly influence the overall latency. Regardless, the database remains online during this step, and connections continue to be directed to the database in the original compute instance. • Switch routing of connections to a new compute instance. Existing connections to the database in the original compute instance are dropped. Any new connections are established to the database in the new compute instance. For some combinations of service tier and compute size changes, database files are detached and reattached during the switch. Regardless, the switch can result in a brief service interruption when the database is unavaila...

In this post, I show how you can automatically scale an AWS DMS replication instance to handle a higher load (scale up) when required and save money (scale down) when the load is low. The use case When setting up an AWS DMS replication instance, you likely analyzethe following: • The number of tables in the database • The volume of data in those tables • Number of concurrent replication tasks • Traffic to the source database In order to have the AWS DMS replication instance right-sized, you must be able to predict the right resource utilization (CPU). Dynamic sizing solution overview Here is the diagram of the architecture. The AWS DMS best practices I use AWS DMS is a region-based service. If you want to use multiple regions, you will need to set up your alarms and resources in each AWS Region separately. Getting started and prerequisites To get started with this solution, you’ll need a AWS account. Follow the CloudFormation user guide to To log in to the AWS CloudFormation console, follow the instructions in the Some of the resources deployed in this blog post, including those deployed using the provided CloudFormation template, will incur costs as long as they are in use.
