The document discusses an incident involving Ceph, an open-source distributed storage system, where an OSD (Object Storage Daemon) reached 90% capacity, causing read/write issues. It details the troubleshooting steps taken to resolve the problem, including monitoring the Ceph cluster health and eventually upgrading to Ceph 3.1 to fix underlying bugs. The recovery process involved reconfiguring virtual machines and addressing data inconsistencies.

- AWS CDK (Cloud Development Kit) allows users to define AWS infrastructure as code using common programming languages rather than JSON/YAML templates.
- It generates CloudFormation templates from source code and provides pre-defined constructs that implement AWS best practices to reduce code needed.
- To use AWS CDK, users need to install the CDK CLI, set up a development environment for their preferred language (TypeScript, Python, Java, C# supported), and deploy their code which will provision resources by generating and executing CloudFormation templates under the hood.
This document discusses DNS and Amazon Route 53. It begins with an overview of DNS records like NS, A, AAAA, CNAME, PTR and MX records. It then covers DNS concepts such as the domain name system, domain name registration and resolution. The document also discusses how Route 53 can be used to configure DNS settings across public and private hosted zones for routing traffic to AWS resources.
