Do you need Pub/Sub or Push/Pull? Is queuing of messages enough or would you need querying or filtering of messages before consumption? Also, someone would have to manage these brokers (unless using managed, cloud provider based solution), automate their deployment, someone would need to take care of backups, clustering if needed, disaster recovery, etc. Why are you considering event-sourcing architecture using Message Brokers such as the above? Won't a simple REST service based arch suffice? Read about CQRS and the problems it entails (state vs command impedance for example). I think something is missing here and you should consider answering it to yourself. Here's a link to Kafka's open source repository on GitHub.Īccording to the StackShare community, Kafka has a broader approval, being mentioned in 509 company stacks & 470 developers stacks compared to Amazon EMR, which is listed in 95 company stacks and 18 developer stacks. Kafka is an open source tool with 12.7K GitHub stars and 6.81K GitHub forks. "On demand processing power" is the primary reason why developers consider Amazon EMR over the competitors, whereas "High-throughput" was stated as the key factor in picking Kafka. Defaults to using persistence, uses OS disk cache for hot data (has higher throughput then any of the above having persistence enabled).Used by LinkedIn to offload processing of all page and other views.On the other hand, Kafka provides the following key features: Flexible Data Stores- With Amazon EMR, you can leverage multiple data stores, including Amazon S3, the Hadoop Distributed File System (HDFS), and Amazon DynamoDB.Some of the features that make it low cost include low hourly pricing, Amazon EC2 Spot integration, Amazon EC2 Reserved Instance integration, elasticity, and Amazon S3 integration. Low Cost- Amazon EMR is designed to reduce the cost of processing large amounts of data.Deploy multiple clusters or resize a running cluster Elastic- Amazon EMR enables you to quickly and easily provision as much capacity as you need and add or remove capacity at any time.

Some of the features offered by Amazon EMR are: It provides the functionality of a messaging system, but with a unique design.Īmazon EMR belongs to "Big Data as a Service" category of the tech stack, while Kafka can be primarily classified under "Message Queue".

Kafka is a distributed, partitioned, replicated commit log service. On the other hand, Kafka is detailed as " Distributed, fault tolerant, high throughput pub-sub messaging system". Customers launch millions of Amazon EMR clusters every year. Amazon EMR is used in a variety of applications, including log analysis, web indexing, data warehousing, machine learning, financial analysis, scientific simulation, and bioinformatics. In order to view the service metrics, you must add the service to monitoring in your Dynatrace environment.Amazon EMR vs Kafka: What are the differences?ĭevelopers describe Amazon EMR as " Distribute your data and processing across a Amazon EC2 instances using Hadoop". To enable monitoring for this service, you first need to integrate Dynatrace with Amazon Web Services:
