As I transition to working in “the cloud” more I am embracing the new technologies and methodologies. However, I’m also trying to replicate what I do in on-prem environments when it makes sense. One way I like to collect and analyze data is using NetFlow. NetFlow provides network conversation details at a higher and summarized level. This has led to quicker recovery time on numerous occasions, or avoided issues entirely.
Performance monitoring is two-fold. There is proactive performance monitoring and reactive investigation. The majority of my posts and case studies reflect the latter. This post is more related to the former. Services on premise typically rely on SLAs, NetFlow, scripts, synthetic transactions and more to provide monitoring and alerting. While some of this is possible in the cloud to keep track of specific pieces, you first need a good foundation by knowing if the underlying technology by your cloud provider is operating as expected.
