In this episode, we provide an overview of Amazon Aurora, a relational database solution on AWS. We discuss its unique capabilities like distinct storage architecture for better performance and faster recovery. We cover concepts like Aurora clusters, reader and writer instances, endpoints, and global databases. We also compare the serverless versions V1 and V2, noting that V2 is more enterprise-ready while V1 scales to zero. We touch on billing and additional features like the data API, RDS query editor, and RDS proxy. Overall, Aurora is powerful and scalable but not trivial to use at global scale. It's best for serious enterprise use cases or variable traffic workloads.

In this episode, we discuss 5 different ways to extend CloudFormation capabilities beyond what it natively supports. We started with a quick recap of what CloudFormation is and why we might need to extend it. We then covered using custom scripts and templating engines, which can be effective but require extra maintenance. We recommended relying instead on tools like Serverless Framework, SAM, and CDK which generate CloudFormation templates but provide abstractions and syntax improvements. When you need custom resources, CloudFormation macros allow pre-processing templates, while custom resources and the CloudFormation registry allow defining new resource types. We summarized recommendations for when to use each approach based on our experience. Overall, we covered multiple options for extending CloudFormation to support more complex infrastructure needs.

In this episode, we discuss best practices for working with AWS Lambda. We cover how Lambda functions work under the hood, including cold starts and warm starts. We then explore different invocation types - synchronous, asynchronous, and event-based. For each, we share tips on performance, cost optimization, and monitoring. Other topics include function structure, logging, instrumentation, and security. Throughout the episode, we aim to provide a solid mental model for serverless development and share our experiences to help you build efficient and robust Lambda applications.

In this episode, we provide commentary and analysis on the 2024 AWS Community Survey results. We go through the key findings for each area including infrastructure as code, CI/CD, serverless, containers, NoSQL databases, event services, and AI/ML. While recognizing potential biases, we aim to extract insights from the data and share our perspectives based on experience. Overall, we see increased adoption across many services, though some pain points remain around developer experience. We hope this format provides value to listeners interested in cloud technology trends.

In this episode, we provide an overview of Amazon EBS, which stands for Elastic Block Storage. We explain what block storage is and how EBS provides highly available and high-performance storage volumes that can be attached to EC2 instances. We discuss the various EBS volume types, including GP3, GP2, provisioned IOPS, and HDD volumes, and explain how they differ in performance characteristics like IOPS and throughput. We go over important concepts like IOPS, throughput, and volume types so listeners can make informed decisions when provisioning EBS. We also cover EBS features like snapshots, encryption, direct API access, and ECS integration. Overall, this is a comprehensive guide to understanding EBS and choosing the right options based on your workload needs.
