In the first two parts of this series, we understood the importance of cost models and how to create and refine cost models. In the subsequent parts, we learned how to optimize our workload components across infrastructure, applications, and data. In this final part, we will present the impact and results related to applying the cost optimization and ShiftLeft FinOps techniques for a cloud-native application.

Continuous delivery demands continuous security. To make continuous delivery possible, observability and security need to go hand in hand. In today’s rapidly evolving business and technology landscape, organizations often prioritize the speed of development over security. The concern is that comprehensive application security in CI/CD environments is too hard to achieve and would slow down development and delivery.

A trivial performance optimisation to help speed up third-party or other-origin requests is to preconnect them: hint that the browser should preemptively open a full connection ( DNS , TCP , TLS ) to the origin in question, for example: In the right circumstances, this simple, single line of HTML can make pages hundreds of milliseconds faster ! But time and again, I see developers misconfiguring even this most basic of features.
