Server-less computing is a distinct shift in application development. It enables developers to focus on writing codes without the hassles of infrastructure that is zero server management, no up-front provisioning, auto-scaling, and paying for services used. Companies that adopt these new approaches enjoy a lower cost of development and operations, release software faster, innovate quickly, and harness the cloud’s latest capabilities to gain an advantage over their rival firms. These cloud services have been applied with in-depth knowledge of the underlying software and huge investments in simplification, reliability, and security.
Functions are the compute engine in a server-less architecture providing a fully managed execution of common software language runtime environments. Code is uploaded as a zip file, in a managed container that activates, reads an event, processes the request, and becomes dormant for each application request. Software functions can be refactored using server-less technologies like AWS Lambda. AWS lets you run code for practically any application or back-end service, all with zero administration. Clients can find ways to improve their operations by changing the way they provision, publish, and code to production through continuous integration of (CI/CD) practices.
Cloud Functions is Google Cloud’s event-driven server-less compute platform. It lets you build in-depth server-less apps easily without having to provision servers. It automatically scales based on the load and simplifies complex application development across all languages, built-in security, distributed tracing, and key networking ability for hybrid and multi-cloud scenarios. For example, Blue Silver has leveraged Azure Functions and Logic Apps to build on many server-less applications. Kubernetes enables you to run workloads anywhere, fully managed on Google Cloud, on-premises, or on a third-party cloud provision like Anthos.
