Highlights of the Aurora Serverless V2 Presentation
Introduction to Aurora and Aurora Serverless
- Aurora is a MySQL and PostgreSQL compatible relational database built for the cloud.
- Aurora Serverless is a feature of Aurora that provides on-demand, auto-scaling configuration for the database.
- Aurora Serverless V2 is the latest version that offers enhanced auto-scaling capabilities.
Challenges with Database Capacity Management
- Provisioning the right database resources is difficult, often leading to over-provisioning or performance issues.
- Managing hundreds or thousands of databases across multiple applications is complex.
- Dealing with workload variability and the need for scaling up and down is a significant challenge.
Benefits of Aurora Serverless V2
- Automatic, in-place, and non-disruptive scaling of database capacity based on workload.
- Ability to scale up and down in small increments (as little as 0.5 ACU) to match the precise needs of the application.
- Instant scaling with no downtime, allowing the database to instantly consume more resources as needed.
- "Pay-as-you-go" billing model, where you only pay for the resources consumed.
- Automatic pause and resume functionality, allowing the database to scale down to zero ACUs when idle.
How Aurora Serverless V2 Scaling Works
- Scaling is based on three key factors: CPU utilization, memory utilization, and network throughput.
- The database scales by allocating more resources to the running database process, rather than failover to a new instance.
- Scaling is done in a fine-grained manner, with the ability to scale up or down in increments as small as 0.5 ACU.
- The scaling algorithm uses a "bucket" of ACUs, with a variable bucket size and refill rate to enable faster scaling for larger database capacities.
Other Aurora Serverless V2 Features and Use Cases
- High Availability and Disaster Recovery: Ability to mix and match provisioned and serverless instances within the same Aurora cluster.
- Analytics and Business Intelligence: Seamless integration with Amazon Redshift Serverless for near real-time analytics.
- Application Connectivity: Data API for simple, driver-less connectivity to the database.
- Limitless Scaling: Serverless-powered "Limitless" scaling for PostgreSQL, supporting terabytes of data and millions of transactions.
Billing and Getting Started
- Billing is based on Aurora Capacity Units (ACUs) consumed per second, with no minimum or hourly billing.
- You can set minimum and maximum ACU limits to control costs.
- Migrating from provisioned Aurora or Aurora Serverless V1 to Aurora Serverless V2 involves a failover process.
- New Aurora Serverless V2 clusters can be created with a few clicks in the AWS Management Console.
Overall, the presentation highlights how Aurora Serverless V2 can help customers overcome the challenges of database capacity management, enable cost optimization, and provide a seamless, scalable database experience.
