How did you overcome a major issue or setback in one of your projects?

At Centercard, I was leading a team of DevOps team - being a startup we had to make some choice due to budgetry constraints. I had to choose between Hosted ELK or hosting our own ELK on EKS. Initially it sould be a good idea to go with EKS option as It would enable us to save around 30% as opposed to Hosted ELK based on our calculation at the time. Team went ahead and deployed and for a while it worked, before going to prod. while doing load testing there was an update to our K8 cluster causing ELK to go down, it took DevOps team sometime to figure out the root cause. This caused dealy in the project, I had to revert course and go with Hosted ELK as at that time, I realized my team was not prepared any downtime in production. In the end the migration was smooth and we did not have any customer impact, apart from the slight delay in the release. Lesson I leant is that I should be able to access strenght and areas of improvement for my team and play to their strength.
