Operations is a nightmare (module X is failing, who’s the owner?) Difficult to scale New releases take months Long time to add new features Architecture is hard to maintain and evolve Lack of innovation Frustrated customers Lack of agility

Using AWS Lambda Bring your own code • Node.js, Java, Python, C#, .Net Core 2.0, GO, Ruby • Bring your own libraries (even native ones) • Layers Simple resource model • Select power rating from 128 MB to 3 GB • CPU and network allocated proportionately Flexible use • Synchronous or asynchronous • Integrated with other AWS services Flexible authorization • Securely grant access to resources and VPCs • Fine-grained control for invoking your functions
