We have previously shown how easy it is to set up Kafka Connect to stream to and from external systems.

Kafka Connect saves you effort by providing a common framework to connect Kafka with external systems using Connectors.

If you work with Postgresql you have most probably heard about PGBouncer. It’s a lightweight external connection pooler which allows…

What is SUSE Rancher?

Want some security tips and context for cloud-native platforms in financial services?

I’ve been using Amazon MSK for some time and today I encountered an interesting problem with autoscaling. Read more to find out!

At Digitalis we have embraced SUSE Rancher and became Gold partners with SUSE Rancher. Do you want to know why? Keep reading.

Terraform is a brilliant tool to manage Infrastructure as Code we at Digitalis both love and hate in equal measure.

We’re going to look at how to manage network policies in Kubernetes with Calico.

The built-in ones are good for most use cases. They are pretty granular covering access to Rancher itself down to individual projects or…

This blog shows you how and provides a fully working Ansible project on Github to install Kafka and manage its security.

If you want to understand how to easily ingest data from Kafka topics into Cassandra than this blog can show you how with the DataStax Kafka Connector.

The most common way of keeping track of your changes to Ansible is using version control. This blog discussed approaches to version control and managing dependencies for Ansible projects.

In this topic, I will explain how to monitor docker containers running on an ECS cluster. Even though AWS CloudWatch is the preferred tool for monitoring and collecting container metrics, in some scenarios it is required to use alternative solutions.

There are many different options that control the behaviour of the backup process and how it determines what files to copy, link or delete, this blog describes how to build a simple incremental backup solution using rsync and hard links.

A short blog on how to monitor SSL certificate expiry on databases such as Apache Cassandra using Prometheus and visualise on a Grafana dashboard.

Variable scoping can be quite complicated on Ansible and it’s important to know what variable your playbook is going to be using. But sometimes it’s not as easy as it may appear and I’d like to run you through a scenario we found where the results were quite what was expected.

In this post I will create a Kafka topic and, using the command line tools to alter the retention policy and then confirm that messages are being retained as we would expect them too.

One of our customers have a short TTL for an IoT use case. The data model is a standard Cassandra time series with a sensor ID as the partition key and timestamp as the clustering column. There was a requirement by this customer to retrieve some data that was already purged due to TTL.

This blog looks at how to use Molecule to test roles in isolation, as no one is perfect and we all make mistakes but many can be avoid with careful planning.

This blog outlines some good practices that can help you secure your Apache Cassandra clusters.
