A recent implementation of Confluent was at a wireless company leveraging Kafka as an IoT streaming platform for bidirectional and cross-region data replication. Their network connects phones, tablets, cameras, robots, sensors, and many other IoT devices in the area. For a wireless IoT system, an IoT controller is a critical component, as it provides the central point of control for all devices in the network. It needs to be reliable and secure, with full observability. The IoT controller helps in managing devices, optimizing their performance, and ensuring their security and reliability. Due to the criticality of the component, the company needed a solution that could help in providing a 99.999% uptime SLA. So they used Confluent Cloud as the streaming platform between their multiple regions within AWS using Cluster Linking over Transit Gateway.
Confluent Cloud provides a variety of features to simplify the deployment, management, and scaling of Apache Kafka in the cloud.
Enables users to create and manage Apache Kafka clusters without the need to deal with the underlying infrastructure.
Supports deployment across multiple cloud providers, allowing users to choose the cloud platform that best fits their requirements.
Includes a variety of pre-built source and sink connectors that simplify the integration of Kafka with other data systems.
Includes Schema Registry, which helps manage and evolve the schemas of messages exchanged in Kafka topics.
Provides security features such as encryption in transit and at rest, access control lists (ACLs), and integration with cloud provider security services for a secure Kafka environment.
Includes monitoring tools and metrics to help users track the performance and health of their Kafka clusters.
Allows automatic scaling of Kafka clusters based on the workload, allowing for efficient resource utilization and performance optimization.
Confluent’s Cluster Linking can be used in conjunction with other technologies and best practices to help achieve high availability and reliability.
To achieve a 99.999% SLA, which translates to less than 5 minutes of downtime per year, the customer would typically need to implement a combination of high availability and disaster recovery technologies, such as:
Load balancing: Distributing traffic across multiple servers or clusters to ensure that no single server or cluster is overwhelmed.
Redundancy: Having multiple servers or clusters that can take over if one fails, either through active-passive or active-active configurations.
Failover: The ability to automatically switch traffic to a backup server or cluster if the primary one fails.
Data replication: Replicating data across multiple servers or clusters to ensure that data is not lost in the event of a failure.
Disaster recovery: Having a plan and procedures in place to recover from a major outage or disaster, such as a backup data center or cloud-based recovery solution.
Cluster linking: By combining these technologies with Cluster Linking, you can create a highly available and resilient system that can provide a 99.999% SLA. Cluster Linking helps identify relationships and patterns between different data points, which can be used to optimize the performance and reliability of the system.
Cluster Linking bidirectional mode (a bidirectional cluster link) enables better disaster recovery and active/active architectures, with data and metadata flowing bidirectionally between two or more clusters.
A useful analogy is to consider a cluster link as a bridge between two clusters.
By default, a cluster link is a one-way bridge: topics go from a source cluster to a destination cluster, with data and metadata always flowing from source to destination.
In contrast, a bidirectional cluster link is a two-way bridge: topics on either side can go to the other cluster, with data and metadata flowing in both directions.
In the case of a bidirectional cluster link, there is no “source” or “destination” cluster. Both clusters are equal, and can function as a source or destination for the other cluster. Each cluster sees itself as the “local” cluster and the other cluster as the “remote” cluster.
In an active/active setup, a bidirectional cluster link ensures that consumer offsets are synced to both clusters, so that consumers and producers can easily failover to the other cluster and resume from the right place.
Below is the customer’s implementation of this solution, showing how they leveraged Confluent Cloud and enterprise features including Cluster Linking as a bidirectional tool between their multiple regions with a cloud service provider. This was a great example of cross-region data replication with Cluster Linking over Transit Gateway.
Confluent’s technical solution for this use case comprises the following:
Streaming data pipelines:
IoT devices like phones, tablets, cameras, and sensors send device metadata to microservices that persist the data MongoDB Atlas database.
There is a topic created for every sensor device. These topics are ephemeral.
Data from multiple sensors is consolidated using Confluent and streamed back into the target MongoDB database from where it is consumed by other consumers across the organization and downstream applications such as Snowflake for reporting and analytics.
Stream processing transforms and enriches IoT telemetry data in real time for monitoring, alerting, improved operational efficiency, and faster and more intelligent decisions.
This data is replicated across regions with Cluster Linking for greater availability and durability.
Confluent cluster types:
Production: 2 Multi-Zone Dedicated Clusters (Multi-Region) connected over AWS Transit Gateway
Load: 1 Multi-AZ Dedicated Clusters (Multi Region) - AWS Transit Gateway
Staging: 1 Multi-AZ Standard Cluster - Public Endpoints
Development: 5 Single AZ Basic Clusters - Public Endpoints
Confluent connectors:
MongoDB Atlas Source: This is a fully managed Confluent connector that moves data from a MongoDB replica set into an Apache Kafka cluster. The connector configures and consumes change stream event documents and publishes them to a Kafka topic.
MongoDB Atlas Sink: This is a fully managed Confluent connector that maps and persists events from Apache Kafka topics directly to a MongoDB Atlas database collection. It supports Avro, JSON Schema, Protobuf, JSON (schemaless), String, or BSON data from Kafka topics. The connector ingests events from topics directly into a MongoDB Atlas database, making the data available for querying, enrichment, and analytics.
Here is a sample SQL query for stream processing to create reusable data products from IoT data collected:
