A multi-protocol proxy for connecting clients and services to Confluent Cloud.
Overview
Zilla Plus is a Kafka-native edge and service proxy. It is a flexible, secure, and reliable way of creating stateless API entry points into your Confluent Cloud cluster for both native and non-native Kafka clients, removing the need for Kafka Connectors, integration pipelines, custom code, and VPNs.
Use Zilla Plus to securely expose your Confluent Cloud cluster to external partners, decouple clients and brokers for disaster recovery, stream data to web/mobile apps for real-time experiences, turn Confluent Cloud into an IoT broker, and more!
[SECURE PUBLIC ACCESS] Enable authorized clients to access your privately-networked Confluent Cloud cluster via a custom domain name over the internet with no changes to underlying brokers. Supports IAM, SASL and mTLS authentication via integrations with AWS Secrets Manager and AWS Certificate Manager (including AWS Nitro Enclaves for automated certificate renewal).
Multiple Zilla Plus instances require only a single NLB, even with multiple brokers. The presence of an NLB ensures that publicly reachable Zilla Plus endpoints to Confluent Cloud can be DDoS-protected via AWS Shield.
[WEB STREAMING] Expose Confluent Cloud topics via SSE (Server Sent Events) endpoints and stream messages to web and mobile clients at scale with reliability and security. Create REST endpoints for clients to POST and PUT updates back into Confluent Cloud topics.
[IOT INGEST & CONTROL] Turn Confluent Cloud into a fully-fledged IoT broker, enabling MQTT clients to directly publish and subscribe to topics. Both MQTT messages and client state are stored in Confluent Cloud, removing the need for a separate dedicated MQTT broker.
[GRPC-KAFKA EVENT MESH] Turn Confluent Cloud into a gRPC server and route service method requests and responses to and from topics. Fan out messages from a Confluent Cloud topic to multiple gRPC clients or proxy messages between a gRPC client and server through Kafka, allowing them to communicate as if they are talking directly to each other.
Highlights
- Flexibility: Seamlessly connect both native and non-native Kafka clients to your public or private Confluent Cloud cluster. Declaratively defined Kafka, REST, SSE, gRPC, and MQTT APIs on top of your cluster.
- Security: Integrations with AWS Secrets Manager and AWS Certificate Manager. Support for Confluent Cloud API Keys used by Kafka clients outside AWS.
- Performance: Zilla proxies are stateless and scale out linearly. When multiple Zilla instances are deployed, only a single NLB is required, even if there are multiple brokers present.

Dimensions summary
You pay by the hour for each running instance of Zilla Plus for Confluent Cloud. Pricing scales by the EC2 instance type you choose to run the software on. Each dimension maps to one AWS instance size, from small shared instances up to large memory-, compute-, and GPU-optimized machines. Larger instances carry higher hourly rates because they provide more compute and memory. Your total cost depends on which instance types you select and how many hours you run them. You deploy inside your own AWS environment on EC2, ECS, or Fargate.
Top-of-mind questions for buyers
Each unit is one running EC2 instance of the software, billed per hour by the instance type you select. You pay software charges only while an instance runs. Stopped or terminated instances stop accruing software charges, though underlying AWS storage or reserved resources may still incur separate AWS fees.
You match the dimension to the compute and memory your workload needs. The gateway runs as a stateless proxy, so you can add or remove instances without coordination. Higher-capacity instance types handle more concurrent connections and throughput but bill at higher hourly rates.
Each running instance bills independently at its own hourly rate for the instance type it uses. Your total is the sum of all active instance-hours across every dimension you deploy. Running more instances, or larger instance types, raises the total. You can scale instances up or down as demand changes.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
