- Manipulating this lifecycle to your advantage
- Alternative solutions to lifecycle hooks
- And using Spot Instances to take advantage of cost savings and faster completion of workloads
Intended Audience
- Those implementing Auto Scaling groups in AWS
- Those attempting the AWS DevOps certification exam as this knowledge is essential for this purpose
- For those looking to use this skill right away, the lesson will show you a hands-on example of lifecycle hooks that you can try right now

- Have an understanding of Amazon EC2 Infrastructure, such as availability zones and VPCs, as well as Auto Scaling groups, and use cases for these AWS services
Software Development has been my craft for over 2 decades. In recent years, I was introduced to the world of "Infrastructure as Code" and Cloud Computing.
I loved it! -- it re-sparked my interest in staying on the cutting edge of technology.
Colleagues regard me as a mentor and leader in my areas of expertise and also as the person to call when production servers crash and we need the App back online quickly.
My primary skills are:
★ Software Development ( Java, PHP, Python and others )
★ Cloud Computing Design and Implementation
★ DevOps: Continuous Delivery and Integration
