- 4. Serverless
- 5. Serverless ● Eliminates the need to manage application servers ● Focus on business logic ● No worries about infrastructure growth ● Little time to set up or optimize servers ● Very little charge for services used during the development period(Based on AWS Lambda) ● Easy to integrate with other services ● No need to access server ● Accelerate development
- 6. Serverless - Problems ● Require POC for the migration to serverless architecture ● Require understanding Cloud Provider services (AWS - Lambda, Azure - Function, GCP - Function) ● Require knowing Debugging tools ● Could be more expensive than EC2
- 7. Serverless - AWS Lambda ● Supports all of languages and runtimes (Golang, Node.js, Python, .Net core, Java ...) ● Logging & Monitoring through CloudWatch ● Easy to bind with API Gateway & Application Load Balancer ● Support Websocket and REST API in API Gateway ● No concerns of scale-out ● Enable processing & caching on CloudFront
- 8. Serverless - Serverless Framework ● Easy and Simple code to deploy serverless infrastructure ● Supports language templates ● Biggest community in Serverless ● Supports 8 cloud providers (AWS, GCP, Azure, Kubeless, Spotinst, Cloudflare, Alibaba Cloud, Openwhisk) ● Support SODD(Stack Overflow driven development)
