In this blog, we will explore the latest applications of Kafka cluster managed service in business operations that companies should not miss.

Why Do Businesses Need Kafka?

Before delving into Kafka and how it revolutionizes data storage and processing, let's familiarize ourselves with the concept of real-time data. As the name suggests, real-time data is collected and stored as soon as it is generated. Real-time data is often used in applications that require quick responses and continuous updates, such as:

Financial markets: Tracking stock prices, exchange rates, and other market fluctuations.
Transportation: Tracking vehicle locations, traffic conditions, and other traffic events.
Social media: Updating user statuses, comments, and messages.
Gaming: Providing smooth and real-time interactive gaming experiences.
IoT (Internet of Things): Monitoring data from connected devices, such as temperature sensors, humidity sensors, and surveillance cameras.

It's evident that real-time data is of paramount importance to businesses. Companies need this information for a wide range of applications, including recording and improving customer service, managing products, and optimizing operations. Additionally, real-time data helps monitor and maintain IT infrastructure. Recognizing these benefits, the demand for collecting and processing this type of data is increasing across all businesses worldwide.

Therefore, tools capable of collecting and storing real-time data like Kafka are increasingly being adopted by businesses in all industries. According to statistics, over 80% of Fortune 100 companies are using Kafka.

Recognizing this trend, VNG Cloud is proud to introduce the Kafka cluster managed service – a solution built on the open-source Kafka system to simplify real-time data processing for businesses.

What is Kafka Cluster Managed service?

VNG Cloud's Kafka cluster managed service is built on the open-source Apache Kafka system. Apache Kafka is a distributed streaming platform designed to handle large volumes of data in a scalable and reliable fashion. Developed in 2011 by LinkedIn and later taken over by the Apache community, Kafka is commonly used for enterprise data processing in two ways:

Building real-time streaming data pipelines and applications: Kafka acts as a central hub for collecting data from various sources and storing it in topics. This data is then distributed and processed by multiple connected applications concurrently.
Serving as a message broker: Kafka allows different applications, written in different languages and running on different platforms, to communicate easily with each other using messages. This platform also handles message traffic, ensuring that applications are not overloaded.

However, building and managing a Kafka cluster in-house requires a highly skilled technical team and a significant investment of time and effort. This is not only costly but also diverts business resources from core activities.

GreenNode's Kafka cluster managed service provides a comprehensive solution, enabling businesses to quickly deploy and manage Kafka clusters. With this service, businesses can focus on application development and maximizing data value without worrying about technical issues.

Below is a detailed comparison table between Kafka Cluster DB Managed Service (managed service) from VNG Cloud and traditional Kafka Cluster (self-managed):

Criteria	Kafka Cluster DB Managed Service	Traditional Kafka Cluster
Cluster Management	GreenNode is responsible for managing, maintaining, upgrading, and monitoring the Kafka cluster.	Users manage the entire Kafka cluster themselves, including installation, configuration, maintenance, upgrades, and monitoring.
Configuration and Deployment	Easy to configure and deploy through the web interface or API.	Requires in-depth knowledge of Kafka and system administration skills to install and configure.
Scalability	Easily scalable by adding resources through the management interface.	Requires manual scaling processes, which can be complex and time-consuming.
Monitoring and Troubleshooting	Service provider (GreenNode vDB) provides monitoring tools and troubleshooting support.	You monitor and troubleshoot yourself, requiring expertise and experience.
Cost	Typically lower costs in the long run due to savings on infrastructure investment, operational costs, and personnel costs.	Higher long-term costs due to investment in infrastructure, operations, and personnel.
Flexibility	May have limited customization and control compared to a self-managed cluster.	Allows full customization and control of the Kafka cluster.
Suitable for	Businesses that want to focus on application development and do not want to invest heavily in infrastructure management.	Businesses with a strong technical team that want full control over the system and can handle troubleshooting themselves.

Typical Use Cases of Kafka Service

GreenNode's Kafka service not only provides a solid foundation for real-time data processing but also supports various use cases across industries, from banking and e-commerce to telecommunications and logistics. Here are some typical use cases:

User activity tracking: eCommerce businesses or online service platforms can leverage Kafka to collect and analyze user behavior on websites or mobile applications. This helps personalize the user experience, improve engagement, and increase sales.
IoT data processing: Businesses in manufacturing, telecommunications, or IoT service providers can use Kafka to collect data from millions of IoT devices. This data is then processed immediately to make business decisions, such as optimizing operational efficiency or predicting equipment failures.
System log analysis: Kafka is a powerful tool for collecting and analyzing logs from various systems. This helps businesses quickly identify errors, optimize system performance, and enhance information security.
Payment processing: For financial institutions, fast and secure payment processing is a top priority. Kafka ensures that payment transactions are continuous and uninterrupted, while also supporting the detection of suspicious or fraudulent transactions.

Industries Using Kafka Service

While it may sound complex, Kafka can be used in many business cases across various industries. Today, leading organizations like Target, Microsoft, Airbnb, and Netflix are using Kafka to provide real-time experiences and accurate data to their customers. Some key applications include:

Banking: Kafka helps banks process payments quickly, detect fraud promptly, and analyze customer behavior. This supports banks in building personalized service strategies and optimizing operational processes.
eCommerce: With Kafka, businesses can track customer shopping journeys, from product search to checkout, to make relevant product recommendations and enhance the online shopping experience.
Telecommunications: Telecommunications companies use Kafka to process massive amounts of data from base stations, quickly detect errors, and optimize network performance, ensuring stable operations.
Logistics: Kafka tracks the status of goods in real-time, helping to optimize the supply chain, ensure timely delivery, and minimize risks.
Healthcare: Hospitals can use Kafka to connect and monitor medical sensors that track patient heart rates, blood pressure, or neurological functions. This enables doctors and nurses to continuously update patient conditions and respond promptly to emergencies.
Advertising: In the advertising field, Kafka supports collecting and storing real-time user behavior information. Advertising companies can use this data to provide quick feedback and offer relevant advertising suggestions. For example, when a user searches for product A, ads for this product will appear immediately when the user opens another application.
