catalog / Software Development

Accurate and reliable logging is the cornerstone of good DevOps, allowing developers to easily spot problems and speed up their development processes. In this liveProject, you’ll learn to deliver cloud-based logging by stepping into the role of an SRE for an online retail startup.


You’ll go hands-on to deliver a cost-effective solution that gathers site logs in a central place in real time, then allows users to interact with those logs through an application interface. Your challenges include building your application infrastructure, creating the configuration to send logs to AWS Elasticsearch, and deploying an Elasticsearch cluster on EC2 instances. By the time you’ve completed your project, you’ll be able to use AWS, Terraform, and more to deliver log access and availability—an essential part of any IT infrastructure.


You’ll be able to complete this liveProject with just the resources provided by the free tier of AWS.
