Amazon has a variety of database services that can help you build cutting-edge apps, including Amazon DynamoDB, Amazon RDS, and Amazon Redshift. You can build web-scale applications and run them on the same infrastructure powers, Amazon.com and Netflix.
Amazon DynamoDB
Amazon DynamoDB is a fast and flexible NoSQL database service for all your data storage needs. Amazon DynamoDB gives you low latency performance at 1 millisecond or less and delivers single-digit millisecond latency on all actions. You can easily scale your throughput capacity using the AWS Management Console, AWS SDK, or command-line tools.
Because Amazon DynamoDB is fully managed, it can be used in serverless architectures. The AWS Lambda functions or the AWS Step Functions state machines can directly call the Amazon DynamoDB API using the lambda function proxy integration model.
Amazon RDS
Working with AWS is like baking a cake. Amazon RDS, AWS's database technology, is like the eggs in the batter. The eggs are reliable, they perform well no matter what, and they only need to be put in one place. Now it's time to add flour (Amazon EC2) and sugar (Amazon EBS) to start making our cake rise up right.
With Amazon RDS, you get:
- Scale capacity with just a few clicks without having to worry about upgrading hardware
- A fully managed service so you can deploy applications faster;
- Ease of use with point-and-click management features that enable seamless integration between your applications and databases;
- Automated backups for high availability
Amazon Redshift
Amazon Redshift is a managed, petabyte data service that makes it quite easy and cost-effective to efficiently analyze your own data using the same familiar SQL-based business tools. Amazon Redshift was designed from the ground up for the cloud and optimized for commodity hardware, making it fast and cost-effective to operate.
Redshift is a columnar data warehouse. It's designed to perform well for queries that are aggregations over large amounts of data. As such, it's not a good fit for applications that need to perform small, fast queries on individual records or transactions.
Amazon Database Services
On top of the above-mentioned AWS database solutions, Amazon cloud offers the below database services:
Amazon Aurora
Amazon Aurora offers up to five times better performance than standard MySQL. It provides consistent, low-latency performance at 1/10th of a second for every SQL query, regardless of data volume or workload. Amazon Aurora also offers up to 99.999999999% (11 9's) of durability, so you never have to worry about losing data.
Amazon Aurora is available as part of AWS Database Services, which include Amazon RDS and Amazon Redshift. You can get started with these services by signing up for AWS!
Amazon ElastiCache
Amazon ElastiCache is a fully managed in-memory data store service that scales automatically to match the size of your largest workloads, delivering blazingly fast performance at any scale. This service is available in multiple configurations—from a single node to more than 500 nodes—with each node having up to 64 TB of memory capacity per node (2 TB per core), delivering an average 8X performance improvement over traditional disk-based systems for reads and writes!
Amazon Neptune
Neptune is a graph database service that allows you to store and query relationships between entities using property graphs instead of RDF triples or SPARQL statements like most other NoSQL databases do today. Neptune supports both transactional and non-transactional queries over the same graph data model, allowing you to choose which form of query best fits your application needs.
The Benefits:
1. Purpose-built:
AWS is designed for the cloud and has been since its inception in 2006. AWS Database Services provides a suite of purpose-built services for the cloud and help you build, operate, and scale databases in the cloud.
2. Scalable performance:
With Amazon Aurora, you get up to five times more performance than with MySQL at a price that's about 60 % less than Oracle. Depending on your needs, you can also choose between General Purpose or Storage Optimized configurations.
3. Available and secure:
Amazon RDS is designed from the ground up to be highly available and secure by default. In addition to being fully managed, so you don't have to worry about managing patches, upgrades, or backups, Amazon RDS continuously monitors your DB instance health, automatically provisions capacity as needed, and performs automatic failover if required — all without any application changes or downtime for you or your users.
4. Fully managed
One of the main advantages of using AWS is a fully managed service. This means that Amazon takes everything from hardware to software maintenance and security updates. The only thing you need to worry about is what kind of workloads you want to run on AWS, which isn't much at all!
There are numerous reasons to use the right database for your application, with AWS giving developers access to a range of options. No matter what choice you make, keep in mind the suggestion that Amazon's guide provides: finding the solution that works best for your application is a lengthy and thoughtful process.
