Slack AI: The Path to Multi-Cloud

Here is a concise summary of the engineering blog post in 2-3 sentences: Slack AI migrated from a basic infrastructure to a multi-cloud architecture over three years, driven by the need for a system resilient to regional outages and GPU scarcity. The company first leveraged AWS SageMaker but moved to Amazon Bedrock, a managed LLM service, to gain operational simplicity, immediate model access, and infrastructure efficiency. This migration delivered compounding wins for the engineering team and customers, achieving operational maturity with architectural simplicity, enhanced user experience, and zero customer-facing incidents.
