Serverless computing manages almost all the system administration operations needed to make it easier for programmers to use the cloud, just focus on development possibilities. It offers an interface that significantly shortens cloud programming. Serverless architecture is a software design pattern where applications are managed and hosted by a third-party Cloud Service provider, eradicating the need for server software and hardware management by the developer. Applications are broken up into separate functions that can be planned, managed, invoked and scaled independently.
Different Options for Serverless computing
AWS Lambda is one the first to offer a serverless platform where you run your code and administration is managed (behind the scene) by AWS. It is a service which computes the code without any server. The code is performed based on the reply of events in AWS services such as updating Amazon DynamoDB tables, adding/removing files in S3 bucket, HTTP request from Amazon API Gateway etc.
Azure Functions Serverless computing model that is the on-demand carrying out of functions that is small fragments of code based on events. The Azure Function platform executes the code in multiple threads without obstacles.
IBM Cloud Functions
Based on Apache OpenWhisk, IBM Cloud Functions is a functions-as-a-service (FaaS) programming platform for developing lightweight code that scalably executes on demand. OpenWhisk is an event-driven compute platform also referred to as Serverless computing or as Function as a Service (FaaS) that runs code in response to events or direct invocations.
Google Cloud Functions
Google Cloud Functions is a serverless execution environment for building and connecting cloud services. With Cloud Functions you can write simple, single-purpose functions that are committed to events emitted from your cloud infrastructure and services. Your code executes in a fully managed environment, so there is no need to provision any infrastructure and worry about managing any servers.
The serverless Iron.io platform offers a multi-cloud, Docker-based job-processing facility. Iron.io functions is an open source serverless architecture platform for any cloud – private, public, or hybrid.
It is well-matched with cloud platforms such as OpenStack, Kubernetes, Cloud Foundry, OpenShift and Mesosphere.
Nub8 Serverless architecture consulting service is here to support you comprehend if serverless architecture is the lean transformation your applications need. If it is, to get you on path and re-focused on code, not servers, utilizing the real benefits of Serverless computing platform.
