Not to be outdone, Google has launched with little fanfare a similar effort, Google Cloud Functions.
The strength of the AWS Lambda's approach is that it allows cloud apps to be developed without the overhead of managing a server instance -- a development approach well-suited to API-driven, microservices-based design. Amazon bolstered this development model for Lambda by building strong connections between it and the rest of AWS, especially the Amazon API Gateway. Google Cloud Functions is likely to follow suit, both by adding support for more languages and by deepening the way apps on the service can interact with the rest of Google Cloud.
The third major cloud contender, Microsoft, hasn't created anything similar to AWS Lambda or Cloud Functions, although it seems inevitable given the way Azure aggressively matches functionality with the competition. Azure already has services that could be predecessors to such functionality -- WebJobs, for instance, or the application management functionality in Azure Stack.
Google Cloud Functions currently is in alpha testing. Prospective users need tomake a service request so that they can be whitelisted and allowed to use it.
