Vendor Lock-in

Amazon introduced AWS Lambda in 2014 and was the first cloud provider to offer and popularize this type of service in its cloud computing platform. However, nowadays other major cloud providers offer similar options for building serverless architecture: for example Microsoft with Azure Functions and Google with Google Cloud Functions. However, building serverless applications with a cloud provider inevitably comes with a degree of vendor lock-in as serverless services like AWS Lambda are proprietary and cannot be easily ported to another cloud provider. Therefore building serverless architecture may increase the depedency towards a single cloud provider.
