What factors are contributing to the increased latency in Aviatrix's Transit Network Gateway deployments this quarter?

Introduction

Increased latency in Aviatrix's Transit Network Gateway deployments this quarter is a critical issue that demands immediate attention. As we analyze this product challenge, I'll employ a systematic framework to identify, validate, and address the root cause while considering both short-term fixes and long-term strategic implications.

I'll begin by restating the problem, outlining my approach, and setting a clear agenda for our discussion. My analysis will cover issue identification, hypothesis generation, validation, and solution development, ensuring we leave no stone unturned in resolving this latency issue.

Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent change in our deployment process. Have there been any updates to our deployment pipeline or infrastructure in the last quarter?

Why it matters: Recent changes often correlate with performance issues. Expected answer: Yes, we've implemented a new CI/CD pipeline. Impact on approach: If yes, we'd focus on the new pipeline; if no, we'd look at other factors.

• Considering user impact, I'm curious about the scale of this issue. What percentage of deployments are experiencing increased latency, and how much has the average deployment time increased?

Why it matters: Helps quantify the problem and prioritize our response. Expected answer: 60% of deployments affected, average time increased by 30%. Impact on approach: Higher percentages would indicate a systemic issue rather than an isolated one.

• Thinking about our infrastructure, I wonder if we've seen any changes in resource utilization. Have there been any significant spikes in CPU, memory, or network usage during deployments?

Why it matters: Resource constraints often lead to performance bottlenecks. Expected answer: Network usage has increased by 40% during deployments. Impact on approach: High resource usage would point us towards optimization strategies.

• Considering external factors, I'm curious if this latency increase correlates with any specific cloud providers or regions. Are we seeing this issue across all environments or is it localized?

Why it matters: Helps determine if the issue is internal or related to external dependencies. Expected answer: The issue is more pronounced in certain regions. Impact on approach: If localized, we'd focus on specific provider or regional optimizations.
