Databases play a crucial role in the functioning of an application. Also, the performance of an application is directly dependent on how the underlying database performs for the application. AWS Database Services is a set of databases offered by AWS on the cloud.
Types of AWS Database Services
AWS provides a wide range of fully managed, purpose-built, and relational and nonrelational database services specially designed to handle application requirements. From fully managed database services, a data warehouse for analytics, to an in-memory data store for caching, AWS has got it all.
You will find an AWS Database Service for just about any kind of database requirements. One can import an existing MySQL, Oracle, or Microsoft SQL database into Amazon’s databases or even build their own relational or NoSQL databases from scratch.
Relational Database: In relational databases, the data is usually stored in a tabular format. Relational databases particularly use structured query language (SQL) to run queries to perform operations such as insertion, updating, deletion, and more. AWS provides the following relational database services.
– Amazon RDS
– Amazon Redshift
– Amazon Aurora
Key-Value Database: The key-value database is a type of NoSQL database where the method of having a value attached to a key is used to store data. Meaning that the data is composed of two elements, keys, and values.
– Amazon DynamoDB
In-memory Database: This type of database is primarily based on the main memory for computer data storage. An in-memory database keeps the whole data in the RAM. Meaning that each time you access the data, you only access the main memory and not any disk. And the reason that the main memory is faster than any disk is why in-memory databases are so popular.
– Amazon ElastiCache
Advantages of Amazon AWS Databases
– Highly Scalable: You can scale your database as your application grows without any downtime!
– Fully Managed: Everything, from maintenance to hardware upgrades, is managed by AWS.
– Enterprise-Class: You get the same world-class infrastructure used by Amazon’s giant e-commerce platform.
– Distributed: Now that your application and database exist on separate machines, your application becomes highly fault-tolerant.
– Workforce Reduction: Since AWS manages everything, you do not need a Database Maintenance team in your organization.
To summarizing, AWS Database Services are highly scalable, fully managed services provided by AWS for the Internet-scale applications on a pay-as-you-go model. They offer various databases like relational databases, nonrelational databases. Moving further, let us discuss the types of AWS Database Services.
