Serverless
A cloud computing execution model in which developers are not required to manage server infrastructure. Code executes on demand and is billed based on actual invocation volume, abstracting away the complexity of cold starts, auto-scaling, and hardware maintenance.
Core Facts
Timeline (last 90 days)
In a Serverless deployment environment, storing uploaded files on the local disk fails, because the files are lost after the instance is destroyed and cannot be read by other instances.
Cloudinary's streaming API receives file buffers in memory via Multer and streams them directly to the Cloudinary CDN, returning a public URL to store in the database, thereby solving the problem of image uploads in a Serverless environment.
To address the issue of session loss in serverless multi-instance deployments, the team placed game sessions into GameID tokens using AES-GCM encryption and HMAC signatures, implementing a stateless solution with token rotation each round.
Some serverless and PaaS platforms collect the complete response before returning it, breaking streaming output.
Completing inference within the timeout limits of serverless functions is a detail that beginners often stumble on when deploying AI Agents.
In serverless inference scenarios such as AWS Lambda and Google Cloud Run, instances are frequently recycled and rebuilt, making cold-start issues especially prominent and typically requiring model weights to be pre-cached to same-region object storage or local SSDs.
Stateless architecture means that servers do not retain client session information between requests; each request carries a complete self-describing context, allowing MCP Servers to be load-balanced and horizontally scaled just like ordinary HTTP APIs.
Serverless mode offers more controllable costs during the exploratory phase when traffic is unstable, but latency stability and pricing structure may differ under extremely high concurrency.
Serverless inference refers to a cloud platform dynamically allocating GPU compute in the background, elastically scaling capacity up or down based on actual request volume, while developers only need to call a REST API or SDK without pre-purchasing or reserving GPU instances.
The difficulty of implementing consumer group rebalancing in a Serverless architecture lies in the fact that Serverless instances are inherently stateless and can be destroyed at any time, whereas rebalancing requires negotiation among group members.
