Terraform is a declarative orchestration tool for provisioning and versioning of infrastructure. I have been working with Terraform at my workplace for a while, albeit from a Monitoring-as-Code perspective. Here is how I prepared for and passed the Terraform Certification exam...

Coding is a creative activity that any kid can engage in, and teaching kids how to code should be top of mind for parents and guardians. Here are some of the tips to get your kids excited about coding

The Certified Kubernetes Application Developer (CKAD) program was developed by the Cloud Native Computing Foundation (CNCF). I passed the exam and these notes summarise what you should expect if you’re preparing it.
PGO can significantly improve code performance and resource utilization, potentially saving up to 14% on cloud spending without requiring any code changes. So, why aren’t you using it? Talk to me.
The omission of frame pointers complicated stack walking. .eh_frame came to rescue, allowing stack unwinding without debug symbols. Good news that Fedora and Ubuntu are re-enabling frame pointers.
Symbolisation converts raw memory addresses into human-readable symbols. The roles of DWARF and ELF in the symbolisation process is explored.
eBPF, AI, GPU, sustainability and WASM were the top topics, but there's more...lots of pictures
bpftrace to flamegraph in 3 simple commmands. eBPF allows for the creation of custom programs that can be attached to various points in the kernel, allowing for detailed and efficient monitoring and analysis of system behavior.
If your cloud-native observability strategy or solution does not include continuous profiling using eBPF, then you must go back to the drawing board. Here's why...
Observability lets us understand a system from the outside by letting us ask questions about that system without knowing its inner workings. OTel creates a unified standard for olly.

Distributed tracing provides end-to-end visibility and reveals service dependencies – showing how the services respond to each other to fulfil a request...
Observability does not replace monitoring. They are NOT mutually exclusive; rather, they are mutually reinforcing. Although observability and monitoring are not the same, they are often used interchangeably by vendors and customers alike.

The vulnerability in castle-and-moat security systems is exacerbated by the emergence of micro-services and cloud-native technologies. The question is, how can a Zero trust model be implemented in a Kubernetes environment ?

Here's to the end of one journey at AppD and the beginning of another at Elastic! As I sit here reflecting on the past five years, I can't help but feel a mix of emotions. On the one hand, I am filled with gratitude for the opportunities and experiences that I had at AppDynamics. On the other hand, I am excited for the new challenges and adventures that await me at Elastic.
