- 2. What is serverless? Serverless Computing is a cloud execution ,model in Which the cloud provider dynamically manages the allocation of machine resources. Pricing is based on the actual amount of resources consumed by an application.
- 3. Advantages Of Serverless Computing Physical Servers Datacenters Virtual Servers Datacenters Virtual Servers in the cloud Higher utilization Faster provisioning speed Improved uptime Disaster recovery Hardware independence Trade CAPEX for OPEX More scale Elastic resources Faster speed and agility Reduced maintenance Better availability and fault tolerance
- 4. limitations Physical Servers Datacenters Virtual Servers Datacenters Trade CAPEX for OPEX More scale Elastic resources Faster speed and agility Reduced maintenance Better availability and fault tolerance Still need to administer virtual servers Still need to manage capacity and utilization Still need to size workloads Still need to manage availability, fault tolerance Still expensive to run intermittent jobs Virtual Servers in the cloud 息 2017, Amazon Web Services, Inc. or its Affiliates.

- 8. What does Serverless mean? No servers to provision or manage Scale with your usage Built in availability and fault-tolerance Never pay for idle/unused capacity
- 9. Serverless runs on functions Functions are the unit of deployment and scale This scales per request! 息 2017, Amazon Web Services, Inc. or its Affiliates. All rights reserved.
- 10. How it works?
- 11. Using AWS Lambda Bring your own code Node.js, Java, Python, C# Bring your own libraries (even native ones) Flexible use Synchronous or asynchronous Integrated with other AWS services Simple resource model Select accesability rating from 128 MB to 1-.5 GB CPU and network allocated proportionately Flexible authorization Securely grant access to resources and VPCs Fine-grained control for invoking your functions
- 12. Using AWS Lambda Authoring functions WYSIWYG editor or upload packaged .zip Third-party plugins (Eclipse, Visual Studio) Programming model Use processes, threads, /tmp, sockets normally AWS SDK built in (Python and Node.js) Monitoring and logging Metrics for requests, errors, and throttles Built-in logs to Amazon CloudWatch Logs Stateless Persist data using external storage No affinity or access to underlying infrastructure

- 17. Apache OpenWhisk is a serverless, open source cloud platform that executes functions in response to events without developer concern for managing the lifecycle or operations of the containers that execute the code. (via Apache) Supported runtimes: Node.js, Python, PHP, Swift and Docker Deployment: On-premises or in the cloud Apache OpenWhisk
- 18. Serverless Supported runtimes: Node.js, Python, PHP, Swift and Docker Development Local development via standard tooling and IDEs Web tooling provided by cloud providers Orchestration via Composer
- 19. Summary Use Serverless for ... Variable and irregular loads (can lead to lower costs) Developer productivity for first time experience Inherent auto-scalability Use AWS for ... Mature deployment options, e.g. testing, monitoring Minimal response latency High performance computing without resource restrictions
- 20. Lambda ? Lambda is stateless architect accordingly! Assume no affinity with underlying compute infrastructure Local filesystem and child processes may not extend beyond the lifetime of the Lambda request 息 2017, Amazon Web Services, Inc. or its Affiliates. All rights reserved.
