Discover how Aerospike's Cross Datacenter Replication feature (XDR) transfers data between clusters effortlessly.

This post outlines how to establish connectivity between two Aerospike clusters by leveraging Aerospike's Cross Datacenter Replication (XDR) feature to seamlessly transmit data from a source cluster to a destination cluster, providing high availability for critical data systems.

As the adoption of Kubernetes (K8s) continues to rise, the necessity for efficient management tools for software running on this platform also increases. For users of Aerospike on Kubernetes, this need is addressed by the Aerospike Kubernetes Operator Control (akoctl) tool. This command-line utility offers simplified and streamlined interactions with the Aerospike Kubernetes Operator, providing essential functions that ease the day-to-day operations of Aerospike clusters within a Kubernetes environment.

In this article we focus on establishing connectivity between 2 Aerospike clusters. The goal is to use Aerospike's Cross Data Center Replication feature ( XDR ) to seamlessly send data from a source cluster to a destination cluster. The source cluster needs network visibility of all Aerospike service ports in the remote cluster, and this can present problems, particularly in a Kubernetes environment. Placing a proxy server in front of the private Kubernetes destination cluster can overcome this problem and achieve the desired goal. To demonstrate the solution we start by installing the Kubernetes Operator that will schedule our source and destination databases. In this example, we set up our replication in one direction. Aerospike is capable of supporting 'master/master' replication and provides a conflict resolution mechanism in the event of update clashes. This too could be supported using the XDR proxy.

In this article we focus on side-by-side block and filesystem requests using Kubernetes.​ The driver for this is it will allow us to deploy Aerospike using Aerospike's all flash mode.

Storing database values on a raw block device with index information on file can bring significant cost reductions, especially when considering use cases for Aerospike’s All-Flash. To support such a workload, you can configure Aerospike to use NVMe Flash drives as the primary index store.

When using the Aerospike Kubernetes Operator, the complexity of configuring a high performance distributed database is abstracted away, making the task of instantiating an Aerospike database incredibly easy. However, even though Kubernetes leads us towards expecting equivalent results regardless of platform, we need to be mindful of the peculiarities of individual frameworks, particularly if we are repeatedly iterating processes. ​ This article focuses on AWS EKS provisioned storage which is dynamically created when using the Aerospike Kubernetes Operator. Ensuring that storage has been fully deleted and other redundant resources removed is a necessary housekeeping step if you are to avoid unwelcome AWS charges. ​
