In today's ever-evolving technological landscape, organizations worldwide have adopted Apache Kafka® for its unparalleled scalability and exceptional features, leading to a paradigm shift in how messaging systems are handled. As more and more organizations adopt Apache Kafka as a vital component of their technology stacks, the need for effective Apache Kafka governance becomes paramount.
A common challenge companies face is the inability to effectively govern
and manage access permissions for the numerous topics created,
often numbering in the hundreds or even thousands.
Managing Apache Kafka topics poses significant challenges for companies, often leading to struggles executing the task effectively. Several crucial considerations arise when undertaking this endeavor:
- Authorization and ownership: Determining who has the rights to produce and consume messages on a specific topic and establishing clear ownership are crucial aspects to address.
- Configuration backup and restoration: Establishing robust strategies for backing up and restoring Apache Kafka's configuration is essential to ensure prompt recovery in the face of failures or system disruptions.
- Security measures: Ensuring the proper enforcement of security measures through subscriptions and access controls is paramount to safeguarding sensitive data and preventing unauthorized access.
- Topic promotion: Navigating the process of smoothly promoting topics with thoroughly tested configurations from lower environments to production requires careful planning and coordination.
- Enhancing visibility and awareness: Increasing the visibility and awareness of topics within the organization facilitates better collaboration and knowledge sharing among teams.
Managing a small number of Apache Kafka topics may seem straightforward at first. However, as Apache Kafka usage grows and more applications and teams are added, effective and efficient management can become increasingly challenging. This includes the important task of isolating sensitive topics containing GDPR, HIPAA, or other types of sensitive data. It is essential to ensure that only authorized applications can access these topics to maintain data security and regulatory compliance.
The current system faces several challenges that impede efficiency and effectiveness, posing risks and hindering productivity. Identifying and addressing these typical challenges can enhance operations and optimize overall performance.
Let's explore the key challenges that need to be addressed:
Creating, accessing, and promoting a topic to a higher environment requires extensive email communication, involving approximately 10 emails. This manual approach consumes valuable time and increases potential errors and miscommunication.
Longer lead time
The end-to-end communication and execution of the manual activities take approximately 2.5 hours, excluding the time spent waiting for human responses. This long lead time hampers efficiency and slows down the overall workflow.
The system faces Role-Based Access Control (RBAC) and data security-related challenges. Ensuring proper access rights and safeguarding sensitive information is crucial for maintaining the integrity and confidentiality of the system.
Lack of audit
No proper auditing mechanism is in place to track and monitor requests. This lack of audit trails creates an accountability gap, making identifying and rectifying potential issues or discrepancies challenging.
The absence of a centralized governance setup adds complexity to the system. All actions are initiated through emails, and the request approver list is maintained in spreadsheets or confluence.
The manual release processes, mainly promoting configurations from one environment to another, introduce a significant risk of errors. These errors can cause system outages, leading to disruptions in service and impacting user experience.
Navigating Apache Kafka system failures
Failures are an inevitable part of any system, and Apache Kafka applications are no different. These failures can occur at different levels, including client-side issues where event deserialization creates problems for consumers, as well as infrastructure-related issues that result in the loss of ZooKeeper/Apache Kafka configurations.
In the context of infrastructure failures, let's consider a scenario with 1000 topics, each possessing a unique configuration stored in a ZooKeeper. Now, imagine a situation where a disaster strikes, causing the ZooKeeper to crash and be unable to recover. This raises a critical question: how swiftly can you retrieve the information and reboot your server? It's not just about having methods to store information but also about strategically implementing storage and retrieval processes for efficient recovery.
How to mitigate these problems?
To ensure a fail-safe Apache Kafka system, it is crucial to mitigate these challenges by implementing a robust governance platform. This platform should encompass the following essential capabilities:
- Comprehensive visibility: Providing a holistic view of topics, producers, consumers, schemas, and connectors.
- Secure configuration management: Implementing a four-eye principle-based system for reviews and approvals to maintain the safety and consistency of configurations.
- Notifications: Alerting users about changes to schemas and other configurations.
- Action tracking: Maintaining a detailed record of actions performed by different users for transparent accountability.
