Lino Telera gave a presentation on serverless computing. He began with introductions and background. The presentation covered serverless concepts like Function as a Service, demonstrated building a simple microservice using AWS Lambda that interacts with S3, and discussed integrating functions with services like S3 using Boto. It also showed how functions can be called from devices using skills and discussed running serverless on-premise using OpenFaaS or Pivotal Container Service. The presentation concluded with a Q&A and thanks to sponsors.

Serverless brewbox
- 1. Deep dive into Serverless By Lino «Jan» Telera
- 2. About me… • Lino «Jan» Telera • Blogger (http://blog.linoproject.net) • Ex developer SOA and Frontend • System administrator, cloud architect, CNA coach, Mentor • VCP4-5-6 VCP-Cloud VCP-DT vExpert 2015,2016,2017 • VMworld 2016-2017 official blogger • VMUG.it board member • TechFieldDay delegate since 2016 • DevOPS enthusiast and VMware «code» member • Beer lover!
- 3. • 100.000 Users and 200 local groups • 1 local group in Italy: vmugit (http://www.vmug.it) • In Italy (since 2016) new devops track! • Italian Events in 2018: To be defined... Stay tuned! • VMUG is your place! Join and share your experience!
- 4. Agenda • Serverless concepts • Function as a Service • First Microservice in Lambda • An interaction... • Questions • Eat, drink, funs
- 5. Back to the past brewbox: What is a container • Isolated instances that include • Library • Tools • Business logic • Most fashion: Docker • More and more vendors are «in container» (and sometimes you don’t know!) • Software as a service • Platform as a service • Infrastructure as a service • Monitoring, backup and orchestrators • Storage and computing systems (HCI) • Software defined Network • The container paradigm: • Write your code • Encapsulate in a «box» • Deploy without Sysadmin • Scale start/stop/increase and reduce (app scaling) • Integrate, patch and deliver (Continous integration)
- 6. Near containers some worries! • Scalability: yet I don’t know how is going the future of my application (A cloud paradigm) • Security: attack surface increases a lot! How to address potential issue in containers? • Monitor (performance and cost): what’s the condition to scale? Compute cost is under your control? • What about data resiliency?
- 7. Serverless • is a cloud computing 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, rather than on pre-purchased units of capacity (Wikipedia) • is a natural evolution of Platform As a Service and containers technology that automate the handling and processing respectively data and functions, “templating” the code and keeping the function/data usage as cost model. • Architecture advantage: • Event-Driven • Micro-managed • Cost effective • Auto scaling
- 10. Function as a service • is a category of cloud computing services that provides a platform allowing customers to develop, run, and manage application functionalities without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app. Building an application following this model is one way of achieving a "serverless" architecture, and is typically used when building microservices applications.
- 11. First example with lambda • An on-premise infrastructure send data to Lambda. Signals are stored into a S3 bucket. • Next, data is retrieved by client to check the status
- 12. Just a Suggestion: Using APEX with your IDE • Create profile and IAM access • apex --profile <profile> init • apex --profile <profile> deploy • Write your code! • apex --profile <profile> invoke <function>
- 13. Integrate with S3 with boto • Create S3 bucket • Create IAM role for Function • Create 2 functions (put and get) • Attach IAM role to Function
- 14. Demo1… and questions What will happen?
- 15. Alexa... Ask Linoproject... • It’s possible to call functions using url or using devices... • Skill Example: << Alexa ask Lainoproject: give me the status!>>
- 16. Demo2… and questions What will happen?
- 17. Serverless on-premise? You can! • OpenFaaS: https://github.com/openfaas/faas • OpenFaaS (Functions as a Service) is a framework for building serverless functions with Docker and Kubernetes which has first class support for metrics. Any process can be packaged as a function enabling you to consume a range of web events without repetitive boiler-plate coding. • Pivotal Containr Service: • Pivotal and VMware are applying their deep enterprise expertise to launch PKS™, a commercial release of the open source Kubo technology, to help Global 2000 companies operationalize Kubernetes • https://github.com/cloudfoundry-incubator/kubo-deployment
- 18. OpenFaaS • A community project based on Docker!!!!! • Easy to deploy: https://github.com/openfaas/faas • Bundled with ui and CLI
- 19. Pivotal Container Service Pivotal Container Service: Kubo + Harbor + NSX (and VMware support)
- 20. Summary • Serverless and Function as a Service • Easy to code • Easy to integrate • Secure in execution • AWS Lambda essentials • You could run on-premise with OpenFaaS or PKS
