What Amazon Managed Service for Apache Flink is

Amazon Managed Service for Apache Flink runs Apache Flink applications that transform and analyze streaming data in real time. AWS manages cluster provisioning and setup, job orchestration, monitoring, alarms, and automatic scaling. Teams can build Flink applications with Java, Scala, Python, or SQL; Apache Beam applications use Java. Integrations include Amazon S3, Amazon MSK, Amazon OpenSearch Service, DynamoDB, Kinesis Data Streams, Kinesis Data Firehose, CloudWatch, and AWS Glue Schema Registry. More than 40 Flink connectors are included, and custom integrations are supported. Applications can provide exactly-once processing when their sources, operators, and sinks support the required semantics. Each KPU provides 50 GB of running storage for checkpoints and temporary disk, and optional durable backups support point-in-time recovery. The service is architected for high availability, including Availability Zone failover, with an SLA of at least 99.9% monthly uptime. Pricing is paid, from $0.11, and there is no free plan. Minimum running charges apply to applications and Studio notebooks.
