In today’s world, where digitization is adopted in every industry and every organization, data is generated in huge quantities every second. The emergence of new technologies, applications, and devices will continue to drive data generation at an exponential rate. The amount of data generated in a minute can vary greatly depending on the context, industry, and specific data sources. A Few examples of industries that generate huge data are:
- Social Media
- Internet Usage
- Internet of Things (IOT)
- Financial Transactions
- Streaming Services
This data is generated in real time and it has to be processed quickly as it arrives, to find some useful trends/patterns out of it that can help to develop the business and provide good experience for the users.
To handle the real time events as and when they are generated, a real time streaming service to handle the incoming data and send it to the application is required. Real time streaming platforms will be able to receive the constant large volume of data generated by various sources, process them sequentially and send the data to various end points that is configured.
Kafka is one such real time streaming platform that can perform the following functions.
Receive and send real time events from/to various endpoints
Store streams of records in the order in which records are generated
Real time processing of large volumes of data
Kafka has various distributions. Apache Kafka is a Open Source platform which is available for free and is used by many organizations. Confluent kafka offers much more capabilities than Apache Kafka and provides support as well. AWS MSK is a fully managed streaming platform offered by AWS.

Various components of AWS MSK:
AWS MSK, or Amazon Managed Streaming for Apache Kafka, is composed of several key components:
Apache Kafka Brokers: The Apache Kafka brokers are the central component of an Apache Kafka cluster and are responsible for storing and forwarding data. In AWS MSK, these brokers run on Amazon EC2 instances.
Zookeeper: Apache ZooKeeper is a distributed coordination service that is used to manage the configuration and state of an Apache Kafka cluster. In AWS MSK, ZooKeeper is used to manage the configuration and state of your brokers.
Apache Kafka Topics: Apache Kafka topics are a named stream of records that can be published to and subscribed to by Apache Kafka producers and consumers. In AWS MSK, topics are used to store and forward data.
Apache Kafka Producers: Apache Kafka producers are applications that publish data to Apache Kafka topics. In AWS MSK, producers can be written in any programming language and can run anywhere.
Apache Kafka Consumers: Apache Kafka consumers are applications that subscribe to Apache Kafka topics and process the data that is published to those topics. In AWS MSK, consumers can be written in any programming language and can run anywhere.
Amazon EC2 Instances: Amazon EC2 instances are used to run Apache Kafka brokers in AWS MSK. The EC2 instances are fully managed by AWS and are designed to be highly available and scalable.
Amazon S3: Amazon S3 is used to store backups of Apache Kafka data in AWS MSK. The backups can be used to recover data in the event of a broker failure.
Amazon CloudWatch: Amazon CloudWatch is used to monitor and manage the performance and health of your Apache Kafka cluster in AWS MSK. CloudWatch provides detailed metrics and logging information, allowing you to quickly identify and resolve issues.
Amazon Kinesis Data Streams: Amazon Kinesis Data Streams can be used to ingest and process real-time data streams in AWS MSK. Kinesis Data Streams can be used to ingest data into Apache Kafka topics, allowing you to process the data in real-time.
In conclusion, AWS MSK is composed of several key components, including Apache Kafka brokers, Zookeeper, Apache Kafka topics, producers, and consumers, Amazon EC2 instances, Amazon S3, and Amazon CloudWatch. These components work together to provide a highly scalable and reliable platform for data streaming in the cloud.

Conclusion:
In this article, we have gone through an overview of AWS MSK (Managed streaming for Apache Kafka), the various components/architecture of MSK. MSK is different from other variants of Kafka available because it is end to end managed by AWS. The availability of EC2 instances, network services, monitoring of the service everything is managed by AWS. As a data engineer, one can completely focus on enabling and managing the kafka configuration between the various publishers and subscribers.
In the current trend where data is generated exponentially at a very high speed and quantity, a streaming platform like MSK is required to act as an interface between the data source and the application. MSK can intermediately receive data and send it to subscribers, help overcome any latency issues, can keep the incoming data for a pre-configured time if the subscriber becomes unresponsive or down and the subscriber can receive the data though MSK once it is back online. A streaming platform like Kafka has become a de-facto industry standard and used in many organizations to process data efficiently.
