A standard configuration of Kafka can reach a throughput of 30k messages per second. String. Those APIs are available in multiple programming languages and tightly integrated with AWS SDKs and the CLI. Kinesis is more directly the comparable product. When it comes to configurations, Kinesis only allows for the number of days/shards to be configured. You can contribute any number of in-depth posts on all things data. AWS takes care of the management. Kinesis is designed for easy implementation. Amazon Kinesis, on the other hand, is a simple stress-free process to set up and start using. For any information on Kafka Exactly Once, you can visit the following link. In such a case, the offered delivery speed can be a deciding factor. Amazon's model for Kinesis is pay-as-you-go. There is no one-size-fits-all answer here and the decision has to be taken based on the business requirements, budget, and parameters listed below. Kafka and Kinesis are similarly positioned when it comes to security, with a couple of key differences. Server-Side encryption provides a second layer of security on top of client-side encryption. The architectural differences are important when Kinesis vs Kafka is considered. Since weve hit on this quite a bit in this piece, were sure you can guess the winner here. You get the flexibility and scalability inherent in the system plus the ability to customize it to your needs. . Apache Kafka is an open-source distributed event streaming platform used for high-performance data pipelines, streaming analytics, data integration, and mission-critical applications. Kafka is by far the easiest to set up and get started with, but fleshing out a robust solution may take a bit more work than the "Hello, World" example lets on. Before you can set up a Kinesis Firehose and S3 bucket, you'll need a user with the permissions to create S3 and Kinesis resources. Two such titans can be found in the field of Message Brokers. 24 hours by default. This provides reliable storage, guaranteed message delivery, and transaction management". But to understand these titans, we must first dive into the world of Message Brokers, we also need to talk about what they are and why they are so important. You can also use KDA against a Kafka cluster to deploy your Flink applications. It is an open-source stream-processing software platform. Configure Kinesis Data Firehose to deliver the data to Amazon S3. The key feature inherent in Kinesis is its ability to process hundreds of terabytes of high volume data streams per hour. The key differences between Kafka and Kinesis are mentioned below: Let us discuss the top 5 difference between Kafka vs Kinesis: Both Kafka and Kinesis provide a good platform for real-time data processing, it depends on the organization which one it prefers. The maximum message size in Kinesis is 1 MB whereas, Kafka messages can be bigger. THE CERTIFICATION NAMES ARE THE TRADEMARKS OF THEIR RESPECTIVE OWNERS. The architecture of Apache Kafka is shown below. Since Amazon Kinesis is a cloud-native pay-as-you-go service, it can be spun up easily and preconfigured to integrate with other AWS cloud-native services on the fly. We help startups and SMEs unlock the full potential of data. ALL RIGHTS RESERVED. It has built-in AWS integrations that accelerate the development of streaming data applications. Installing and configuring a Kafka cluster to handle a typical production workload might take weeks. For a month with 31 days, the monthly Shard Hour cost is $44.64 ($1.44*31). The pricing is calculated in terms of shard hours, payload units, or data retention period. For Kinesis, scaling is enabled by an abstraction of the Kinesis framework known as a Shard. Hence, we came up with the following dimensions to compare and contrast them. Amazon's model for Kinesis is pay-as-you-go. By default, Kafka retains data records for up to seven days. But can be extended up to 365 days which would incur a cost. Kafka is designed to operate as a distributed system that could span multiple data centers. Figure 04 - Kafka Connect architecture. The total capacity of the stream is dependent on the number of shards and is equal to the sum of the capacities of its shards. The speed of message delivery differs between SQS, SNS, Kinesis, and EventBridge. As a replacement of the common SNS-SQS messaging queue, AWS Kinesis enables organizations to run critical applications and support baseline business processes in real-time rather than waiting until all the data is collected and cataloged, which could take hours to days. The distributed nature of Apache Kafka allows it to scale out and provides high availability in case of node failure. It is known to be incredibly fast, reliable, and easy to operate. AWS recently announced the Enhanced fan-out feature, where each consumer reading from a shard will get a dedicated throughput of 2MB per second. For instance, popular video streaming platform Netflix uses Amazon Kinesis Data Streams to centralize flow logs for its in-house solution Dredge, which reads the data in real-time from Amazons Kinesis Data Streams and gives a complete picture of the networking environment by enriching the IP addresses with application metadata. While Kafka is a cheaper alternative and stores data for longer periods, it requires complex initial configurations. The above prices are with regards to the US East location and might change with location. Be it financial transactions, social media feeds, IT logs, and location-tracking events. It allows you to propagate events from Kinesis and DynamoDB Streams to other services that . The tiered storage capability is working progress. AWS KMS allows you to use AWS generated KMS master keys for encryption, or if you prefer you can bring your own master key into AWS KMS. The concept of microservices is to create a larger architectural ecosystem through stitching together many individual programs or systems, each of which can be patched and reworked all on their own. We hope this article helped you pick the right technology based on the engineering culture, budgetary constraints, and how critical the role of event streaming plays within your organization. Kafka has been a long-time favorite for on-premises data lakes. Kafkas hashing algorithm depends on the number of partitions. Kinesis Kafka Ecosystem Comparisons. Kinesis is meant to ingest, transform and process terabytes of moving data. ] Kinesis is great for the programmer who wants to develop their software without having to mess with any troublesome hardware or hosting platforms. You may have to spend on additional hardware to fine-tune the cluster performance to handle spikes in workloads. Overall, the Amazon Kinesis vs Kafka choice solely depends on the goal of the company and the resources it has. The key components of the Kafka Ecosystem include Producers, Consumers, Topics. Amazon Kinesis has four capabilities: Kinesis Video Streams, Kinesis Data Streams, Kinesis Data Firehose, and Kinesis Data Analytics. There is something in common and yet they both hold their own significance. Kinesis performance will depend on how the producers are running To scale up you need to run Kinesis producers in parallel. Kinesis organizes its data records into shards. StreamSets supports Apache Kafka as a source, broker, and destination allowing you to build complex Kafka pipelines with message brokering at every stage, and has supported stages for Kinesis too. Multiple producers can simultaneously produce events to a topic while many consumers already consume from the same topic. But there is, however, a third contender. It allows client applications to both reads and writes period the data from/to many brokers simultaneously. So users of .NET would be more inclined towards tilt towards Kinesis than they would Kafka. The best use case would be when you have large data streams between applications. Share your experience of learning about Amazon Kinesis vs Kafka in the comments section below. Lastly, you can use your own encryption libraries to encrypt data on the client-side before putting the data into Kinesis. Much like the Kinesis shard, the more Kafka partitions configured within a Kafka cluster, the more simultaneous reads and writes Kafka can perform. Configure Input stream (kinesis stream, kinesis firehose) a. , sensor metrics, machine learning, artificial intelligence, and other modern-day applications. In fact, you can decide by the size of the data or by date. They stated that: "Looking at Apache Kafka customers by industry, we find that Computer Software (30%), Information Technology and Services (11%) and Staffing and Recruiting (7%) are the largest segments. Although Kafka and Kinesis are highly configurable to meet the scale required of a data streaming environment, these two services offer that configurability in distinctly different ways. http://www.itcheerup.net/2019/01/kafka-vs-kinesis/, More control on configuration and better performance, Number of days/shards can only be configured, Kinesis writes synchronously to 3 different machines/data-centers, Kinesis writes each message synchronously to 3 different machines, Require human support for installing and managing their clusters, and also accounting for requirements such as high availability, durability, and recovery, The Producer API: sends streams of data to topics in the Kafka cluster, The Consumer API: reads streams of data from topics in the Kafka cluster, The Streams API: transforms streams of data from input topics to output topics, The Connect API: implements connectors that consistently pulls from some source system or app into Kafka or push from Kafka into others. Typically, about 1,000 Amazon Kinesis shards work in parallel to process the data stream. Setting up the Firehose service. According to enlyft.com, there are about 12,792 companies that use Apache Kafka. The following are the key factors that drive the Amazon Kinesis vs Kafka decision: Apache Kafkas architecture has producers and consumers playing a pivotal role. This requirement adds additional overhead to the Kinesis platform leading to degradation in performance. In the case of Kafka, the cost primarily depends on the number of Brokers you are using. Unlike a Kafka partition, the throughput of a shard has limits. 1. Performance-wise, Kafka has a clear advantage over Kinesis. Kafka is more highly configurable compared to Kinesis. If you have the in-house knowledge to maintain Kafka and Zookeeper, dont need to integrate with AWS Services and you need to process more than 1000s of events/second then Apache Kafka is just right for you. Updated: September 2022. According to McKinsey, companies with the greatest overall growth in revenue and earnings receive a significant proportion of that boost from data and analytics. But theres a secret to fueling those analytics: data ingest frameworks that help deliver data in real-time across a business. Modernizing data integration for continuous data under constant change. The Kafka-Kinesis-Connector is a connector to be used with Kafka Connect to publish messages from Kafka to Amazon Kinesis Streams or Amazon Kinesis Firehose.. Kafka-Kinesis-Connector for Firehose is used to publish messages from Kafka to one of the following destinations: Amazon S3, Amazon Redshift, or Amazon Elasticsearch Service and in turn enabling near real time analytics . But for a non-existing team scenario, you would be looking at hiring skilled staff or outsourcing the installation and management. Events written to a Kinesis stream can be taken out to other AWS services via AWS Kinesis Data Firehose; the Kafka Connect equivalent connects Kinesis to other ecosystem products like S3, Redshift, and Splunk. A few of the Kafka ecosystem components were mentioned above such as Kafka Connect and Kafka Streams. Set-up: Kafka takes longer to set up than Kinesis. A partition is the smallest unit in a Kafka cluster that stores a subset of events belonging to a topic. You'll need a team to install (and manage) data clusters. Let's not forget that Kafka consistently gets better throughput than Kinesis. These events are read and processed by consumers. Only governed by clusters resources, Both read and write throughput is limited per shard. Just when I thought one had a clear advantage and was a shoo-in, the other would come out with unexpected maneuvers that threw the match up in the air. Consumer applications like stream processors and analytics databases subscribe to a topic and read events using Consumer API. These are gotten from sources such as the web or mobile applications but also e-commerce purchases, in-game activities or the never-ending information generated on social media.

Apache Kafka and AWS Kinesis are two event streaming platforms that enable ingesting a large number of events each second and storing them durably until they are analyzed. Lets not forget that IoT devices are also a source for such large data streams. Here, Kafka is the clear winner. What you would be comparing here is the implementation cost of setting up, running and maintaining a Kafka installation along with the human resources needed, against the hosted nature of Amazon Kinesis. Kafkas scalability is determined by brokers and partitions. We see fierce competition for supremacy by various vendors, each vying for the attention of the consumer space. You get to decide the exact Kafka version, the number of brokers, and their hardware specifications based on the workload. Both Kafka and Kinesis are prominent technologies in the event streaming space. Try the Kinesis price calculator here. According to Wikipedia - "The main function of a broker is to take incoming messages from apps and perform some operations on them. In case you want to integrate data from data sources like Apache Kafka into your desired Database/destination and seamlessly visualize it in a BI tool of your choice, then Hevo Data is the right choice for you! Hopefully, it will provide you with a useful reference for picking between them in the future. Kafka officially provides two types of SDK for Java developers. One has to build frameworks to handle TimeWindows, late-arriving messages, out-of-order messages, lookup tables, aggregating by key, and more. Here, arguments for and against could be made on both sides, and its largely a matter of preference. A decision to choose either of them should be made rationally. Message brokers are architectural designs for validating, transforming and routing messages between applications. Broker sometimes refers to more of a logical system or as Kafka as a whole. Amazon SDKs for Go, Java, JavaScript, .NET, Node.js, PHP, Python, and Ruby supports Kinesis Data Streams. One of the major considerations is how these tools are designed to operate. There are four major APIs in Kafka, namely: Next is the Broker which is a Kafka server that runs in a Kafka Cluster. This article provides you with a comprehensive analysis of both Data Streaming Platforms and highlights the major differences between them to help you make the Amazon Kinesis vs Kafka decision with ease. The analogue is not Kinesis, which is the low-level stream (in turn an analogue but not quite the same as Apache Kafka) - but Kinesis Data Analytics, which is a managed service for Apache Flink. That allows keeping the latest data for a short period (e.g., 48 hours) in the local storage and flushing out the older data into cheap secondary storage like S3 or HDFS. solutions, facilitated by these message brokering services. But this flexibility often comes with a cost. This is a guide to Kafka vs Kinesis. Amazon Kinesis is rated 8.2, while Apache Spark Streaming is rated 7.8. Kafka additionally. The DynamoDB table has the same name as the application_name configuration option, which defaults to "logstash". See also Apache Kafka Architecture - Delivery Guarantees. The key differences between Amazon Kinesis and Kafka are: Data retention: There's a maximum 7-day retention period on Kinesis. Producers are those client applications that write events to Kafka, and consumers are those that read and process these events. A sample calculation on a monthly basis: Shard Hour: One shard costs $0.015 per hour, or $0.36 per day ($0.015*24). Simply put, events with the same partition key will end up in the same partition. While dealing with Kinesis, you would start to notice a bit of limitation on some of its features. This replication cannot be reconfigured, influencing resource overhead such as throughput and latency. Lets not forget the device cost of what you will be running Kafka on. Conclusion.
