Today, the Amazon Builders’ Library published a new article titled, Automating Safe, Hands-off Deployments to help readers understand how Amazon approaches software deployments. AWS Principal Engineer Clare Liguori dives deep into the strategies used at Amazon to continuously deploy software into production while balancing safety and speed. 

The Amazon Builders’ Library is a collection of living articles that take readers under the hood of how Amazon architects, releases, and operates the software underpinning Amazon.com and AWS. The Builders’ Library articles are written by Amazon’s senior technical leaders and engineers, covering topics across architecture, software delivery, and operations. For example, readers can see how Amazon automates software delivery to achieve over 150 million deployments a year or how Amazon’s engineers implement principles such as shuffle sharding to build resilient systems that are highly available and fault tolerant.
