Airbnb : Flexible Continuous Integration for iOS
Summary
Airbnb has upgraded its iOS Continuous Integration (CI) system by leveraging Amazon EC2 Mac instances and automation tools like Packer and Terraform. The previous system running on physical Macs required significant maintenance and lacked scalability. By using AMIs, Airbnb can launch instances without manual intervention and roll out new Xcode versions more efficiently. The system's flexibility enables the creation of multiple CI environments for different CPU architectures and Xcode versions. With this upgrade, Airbnb has seen increased speed in updating Xcode versions and improved scalability for iOS development. Read full article
Key takeaways
Airbnb has implemented a flexible and easy-to-maintain iOS Continuous Integration (CI) system using Amazon EC2 Mac instances.
Previously, Airbnb ran iOS CI on physical Macs, which required substantial maintenance and limited scalability.
With the introduction of Amazon Machine Images (AMIs) and tools like Packer and Terraform, Airbnb can launch instances in a more automated and scalable manner.
They leverage AMIs to add new instances to the fleet without human intervention, reducing maintenance efforts.
The new system allows Airbnb to roll out new Xcode versions more quickly and handle spikes in CI usage effectively.
Uber : Cybersecurity Incident Simulation
Summary
Uber utilizes a three-pronged approach for cybersecurity incident simulations. This includes tabletop exercises, red team operations, and atomic simulations. Simulations focus on processes, collaboration, and leadership awareness. They test detection, response, and investigation capabilities, while also integrating new team members. Uber tracks coverage and aims for continuous improvement to stay prepared for evolving threats. Read full article
Key takeaways
Simulations are crucial to prepare for cybersecurity incidents and ensure effective response.
Uber uses a three-pronged approach: tabletop exercises (TTX), red team operations, and atomic simulations.
TTXs focus on processes, roles, and decision-making, improving collaboration and leadership awareness.
Red team operations mimic real-world attacks to test detection, response, and investigation capabilities.
Atomic simulations test specific aspects, identify areas for improvement, and integrate new team members.
Uber tracks simulation coverage using the MITRE ATT&CK® navigator and aims for continuous improvement.
Simulations help Uber stay prepared for evolving threats and protect their users and employees.
