2. What we do at Candis Some of the projects we work on: • Modularizing our main product to enable us to scale into international markets and offer our users the product they need. • We’re always looking at emerging technologies that could help our users save time and enable new real-time workflows. • Improving the quality of our data extraction pipelines using machine learning and other approaches while maintaining a high level of accuracy. Our TechStacks • Javascript, Typescript • Node, React • MongoDB • AWS • Kubernetes and its surrounding services • Serverless Architecture Social Presence Our Website LinkedIn Kununu Instagram
3. Ok, So Serverless .....
4. What options are available to run code on cloud ? • Bare Metal • IaaS (VM) - AWS EC2 Instance • CaaS (Container) - AWS ECS , Microsoft Azure Container Service (ACS) • PaaS (App) - AWS Elastic Beanstalk, Windows Azure, Heroku, Google App Engine, Apache Stratos. • Serverless (Function - FaaS) - AWS Lambda, Google Cloud Function, Azure Function More Control, More Management, More Code Less Control, Less Management, Less Code
5. Serverless Model Programming Model Operation Model
6. Programming Model • Service Based (Service oriented programming) • Event Driven
7. Service Based Programming
8. Event Driven
9. Operational Model • No server/infra to provision or manage • Flexible Scaling (Auto Scaling) • Pay only for usages • Highly available and secure
10. Who is using Serverless ?
11. AWS Lambda ……..“AWS Lambda lets you run code without provisioning or managing servers. You pay only for the compute time you consume.”
12. AWS Lambda - Pay per use pricing • Pay for compute time in 100ms increment • No hourly, daily or monthly minimum commitment or charges • No per device cost • Never pay for idle 1 Million requests are free every months for ever customer More details on Pricing : https://aws.amazon.com/lambda/pricing/
13. So What AWS Lambda take care for you ? ... • Load Balancing • Auto Scaling • Handling Failures • Security Isolations • OS Management • Managing Resources Utilization • Built-in Metrics / Logs
