Packaged Solution – The best option for simple production and testing environments. This provisions a complete Cadence configuration including the required supporting Cassandra, Kafka and OpenSearch clusters.
Cadence Cluster Only – The most flexible option for environments at all scales. This requires that you have already created the necessary Cassandra, Kafka and OpenSearch clusters and provisions a Cadence cluster to use those existing clusters.
Log into the Instaclustr Console and click the Create Cluster button. This will take you to the wizard for creating a new cluster.
Give your cluster a name, select Cadence as the application, select your desired Cloud Service Provider and click Next.
On the Cadence Setup page, we can select the version of Cadence. We are currently only offering Cadence 0.24.0. Select “Packaged Solution“ as the provisioning approach. Also check the “Use Adavanced Visibility“ option.
On the Cadence Dependency Setup page, select one option from the predefined Cadence Solution Sizes (Developer or Production – Starter or Production – Small) and click Next. This will provision a Cadence cluster and the required Cassandra, Kafka and OpenSearch clusters of the selected (predefined) size in your account and link them together.
Under the Data Centre section, select a Data Centre Region and click Next. The page will also summarise the Cadence and the Cassandra, Kafka and OpenSearch cluster configurations.
The Confirmation section displays a detailed summary of your cluster configurations and pricing details. If you are happy with the cluster configuration and have accepted the terms and conditions, click the Create Cluster button to start provisioning the Cadence cluster and the dependent Cassandra, Kafka and OpenSearch clusters.
Provisioning the 4 clusters will take some time. There are a few additional automated steps required to link these clusters that take place during this time.
You have now finished creating your Cadence cluster (along with your dependent Cassandra, Kafka and OpenSearch cluster)! Now you can focus on creating incredible workflows and leave the cluster operations to us.
Cadence Cluster Only
Step 1 – Configure your supporting clusters
To provision your Advanced Visibility Cadence cluster, you will first need to use Instaclustr’s managed service to provision the prerequisite clusters (i.e. Apache Cassandra®, OpenSearch, Apache Kafka®). This can be done via the Instaclustr Console.
Take care to provision a version 3.11.x Cassandra cluster here, rather than a version 4.x cluster (both versions are provisionable in the console). There are compatibility issues between Cassandra 4 and Cadence that we expected to see rectified in an upcoming Cadence release.
Note: The cluster creation wizard for all three clusters above will offer you the option to designate the cluster as a ‘Bundled Use Only’ cluster, which can enable discounted pricing for these clusters in certain use cases. We recommend reading more about Bundled Use Only Cluster Deployments to assess if this could be an advantageous feature for your use case.
Step 2: Create a Cadence cluster
Now that we have prepared our required clusters, we can create a Cadence cluster and configure it to use them.
Log into theInstaclustr Console and click the CreateCluster button. When prompted, select the Cadence application.
On the Cadence Setup page, we can select the version of Cadence. We are currently only offering Cadence 0.24.0. Select “Cadence Cluster Only“ as the provisioning approach. Also check the “Use Adavanced Visibility“ option.
On the Cadence Dependency Setup page, you will be given the option to specify your supporting clusters for the Cadence cluster, and to configure the connections between the clusters. In each section, select the Cassandra, OpenSearch or Kafka cluster that you wish to use as the supporting cluster. Additionally, you can specify the VPC configuration that you would like to exist between your Cadence cluster and each of the supporting clusters in the VPC Configuration dropdown. Configuring the Cadence VPC gives a detailed explanation about the different approaches to configuring the Cadence VPC.
Under the Data Centre section,
Select a Data Centre Region,
A cluster network address block (Note : Provide a non-overlapping CIDR block for VPC Peering and Cassandra Cluster VPC option),
The number of nodes for your application,
The desired node size.
The Confirmation section displays a brief summary of your cluster configurations and pricing details. If you are happy with the cluster configuration and have accepted the terms and conditions, click the Create Cluster button to start provisioning the Cadence cluster.
Instaclustr’s provisioning system will begin to create the Cadence cluster instances. In the Cluster Details page we can monitor the progress of the provisioning steps. Once the cluster reaches a Running state, you have finished creating your Advanced Visibility Cadence cluster!
