CloudKarafka are managed Apache Kafka servers in the cloud. Kafka is a distributed publish-subscribe messaging systems that is designed to be fast, scalable, and durable. It's an open-source message broker written in Scala, that can support a large number of consumers, and retain large amounts of data with very little overhead.
CloudKarafka automates every part of setup, running and scaling of Apache Kafka. We have support staff available 24/7 to help in any event or with any questions. CloudKarafka let developers focus on the core part of their applications, instead of managing and maintaining servers.
To get started with CloudKarafka, you need to sign up for an account and create a CloudKarafka instance.
Create an account and login to the control panel and press Create+ to create a new instance. Choose a name for the instance and the datacenter to host the instance. To get started you need to sign up for a customer plan. What plan you want to use depend of your needs. We offer five different plans for different needs. You can try CloudKarafka for free with the plan Developer Duck.
All plans are billed by the second, you can try out even the largest instance types for mere pennies. As soon as you delete the instance you won't be charged for it anymore. Billing occurs at the end of each month, and you are only charged for the time an instance has been available to you.
The instance is immediately provisioned after creation and you can view the instance details at the details page.
When you have signed up and created your instance it is time to Get started with CloudKarafka. Before you start coding you need to either download certificates or set up a VPC peering to your AWS VPC.
Our shared instances are on a multi tenant Kafka server. You share the server with other users. To get started with your shared instance you need to download the Certificates (Connection Environment variables) for the instance from the instances overview page. You will find the Certs download button as in the picture above. Press the button and save the given .env file into your project. If you signed up via a provider you can get all the connection variables you need from the provider. In the documentation language pages you will see examples of how to handle the environment variables (certificates) in different languages. Some languages require a path to the cert-file, in that cases you first need to write the .env certificate information to a file. Other languages can read and handle the certificates stright from the environment variables. See the language specific documentation for more information.
When you create your instance you will get a topic by default. You are allowed to add up to 5 topics to your instance. A new topic can be added by entering the details page for your instance.
A secure connection has to be set up between you clients and your CloudKarafka server. You need to create certificates or you need to peer your instance with your AWS VPC.
Press on the details page for your instance and open up the VPC Peering tab. CloudKarafka will request to set up a VPC connection to you as soon as you have saved your VPC peering details. After that you need to accept the VPC peering connection request from us. The request can be accepted from the Amazon VPC console at https://console.aws.amazon.com/vpc/. Please note that the subnet given must be the same as your VPC subnet.
We do allow connections via certificate based authentication. You can find information about how to set up the certificates in the details page of your instanes under the Cert Management tab. When you have followed all steps in the Cert Management guide you will have one private key, the CA cert and a signed client cert which allowes you to connect. Language specific code can be found in the documentation menu.
Apache Kafka log stream shows the live log from Kafka.
The Server Metrics helps you to measure performance metrics from your server. CloudKarafka shows monitoring for CPU Usage, Memory Usage, and Disk Usage.
Kafka Manager is a a tool for management of Apache Kafka.
There are a some concepts that is good to be familiar with before you get started with your first CloudKarafka instance.
