Automating Infrastructure as Code with Apache Kafka and Confluent ft. Rosemary Wang

  • Transcript
  • Notes

Managing infrastructure as code (IaC) instead of using manual processes makes it easy to scale systems and minimize errors. Rosemary Wang (Developer Advocate, HashiCorp, and author of “Essential Infrastructure as Code: Patterns and Practices”) is an infrastructure engineer at heart and an aspiring software developer who is passionate about teaching patterns for infrastructure as code to simplify processes for system admins and software engineers familiar with Python, provisioning tools like Terraform, and cloud service providers. 

The definition of infrastructure has expanded to include anything that delivers or deploys applications. Infrastructure as software or infrastructure as configuration, according to Rosemary, are ideas grouped behind infrastructure as code—the process of automating infrastructure changes in a codified manner, which also applies to DevOps practices, including version controls, continuous integration, continuous delivery, and continuous deployment. Whether you’re using a domain-specific language or a programming language, the practices used to collaborate between you, your team, and your organization are the same—create one application and scale systems.

The ultimate result and benefit of infrastructure as code is automation. Many developers take advantage of managed offerings like Confluent Cloud—fully managed Kafka as a service—to remove the operational burden and configuration layer. Still, as long as complex topologies like connecting to another server on a cloud provider to external databases exist, there is great value to standardizing infrastructure practices. Rosemary shares four characteristics that every infrastructure system should have: 

  1. Resilience
  2. Self-service
  3. Security
  4. Cost reduction

In addition, Rosemary and Tim discuss updating infrastructure with blue-green deployment techniques, immutable infrastructure, and developer advocacy.

Real-Time Stream Processing with Kafka Streams ft. Bill Bejeck

Kafka Streams is a native streaming library for Apache Kafka that consumes messages from Kafka to perform operations like filtering a topic’s message and producing output back into Kafka. After working as a developer in stream processing, Bill Bejeck (Apache Kafka Committer and Integration Architect, Confluent) has found his calling in sharing knowledge and authoring his book, “Kafka Streams in Action.” As a Kafka Streams expert, Bill is also the author of the Kafka Streams 101 course on Confluent Developer, where he delves into what Kafka Streams is, how to use it, and how it works.

Handling Message Errors and Dead Letter Queues in Apache Kafka ft. Jason Bell

If you ever wondered what exactly dead letter queues (DLQs) are and how to use them, Jason Bell (Senior DataOps Engineer, Digitalis) has an answer for you. Dead letter queues are a feature of Kafka Connect that acts as the destination for failed messages due to errors like improper message deserialization and improper message formatting. Lots of Jason’s work is around Kafka Connect and the Kafka Streams API, and in this episode, he explains the fundamentals of dead letter queues, how to use them, and the parameters around them.
