This document announces six virtual developer meetups on cloud native application development using Oracle Cloud Infrastructure services. It provides details on individual meetup sessions focusing on functions, API gateway, streaming, and NoSQL database. It encourages attendees to sign up for an Oracle cloud trial and complete hands-on labs accessing these services through the command line interface. Guidelines are provided on setting up access to services like functions, API gateway, streaming and NoSQL database and using them to build cloud applications. The document aims to introduce developers to capabilities of these services through practical hands-on scenarios and demos.
Part 3 of the REAL Webinars on Oracle Cloud Native Application Development (June 2020)
- 1. Six Virtual Developer Meetups Cloud Native Application Development on Oracle Cloud Platform http://bit.ly/real-oci Wednesday June 24th โ Advanced Functions Functions on OCI | API Gateway | Streaming | NoSQL Database | Object Storage
- 3. Touring Oracle Cloud services for cloud native application development Introduction Demonstration Guided Handson Labs Q&A All sessions are recorded and will be available for replay
- 5. Preparation for the Katacoda Hands-On Labs โข Arrange access to Oracle Cloud Infrastructure Tenancy โข Existing or new OCI Cloud Trial โข Existing OCI tenancy โข Go to http://bit.ly/real-oci home of the REAL Katacoda scenarios for OCI โข Run First Scenario to prepare the OCI tenancy for REAL Katacoda OCI Scenarios โข Provision an OCI compartment and some resources โข Prepare auth token, key pair and config file for using the OCI CLI in other scenarios Go http://bit.ly/real-oci
- 6. Cloud Trial as Registered Webinar Attendee โข Signup for Cloud Trial with same email address as used for webinar registration โข Use a company email address (not gmail or hotmail); do not use an address already used for an Oracle Cloud Trial โข Do not use credit card โ because email is whitelisted (as of tomorrow, June 11th) โข You will get โข $500 credits on (discounted) Oacle cloud services โข Access to always Free Tier cloud.oracle.com/tryit

- 8. Functions API Gate way Object Storage NoSQL Database Streaming OCI Services for Cloud Native Application Development
- 9. Scenario on Functions + API Gateway + Object Storage
- 10. Why and What a Katacoda Scenario for Functions + API Gateway + Object Storage? โข Have an integrated scenario (Functions, Node, Gateway, Storage) โข Keep testing the CLI for different scenarios โข Differentiate calling a function directly and via the OCI API Gateway โข Show the integration between Node.JS and Object Storage โข Continue using the elements of previous scenarios (API GTWY) โข Automate all tasks via OCI CLI โข Test Functions via CLI โข Test APIs via CLI โข Validate contents within the Object Storage
- 11. OCI Streaming Service โข Kafka Like โ Event Queue โข Support for partitions and consumer groups โข Events are Published and Consumed through REST API calls โข Java SDK available โข No Push to Consumer! Oracle Cloud Infrastructure Listener OCI Streaming StreamPublisher On prem Listener Listener 3rd Party Cloud
- 12. โข Message retrieval is done through a Cursor โข Similar to a (long running) query โข Cursor indicates where to read from Stream โข Earliest, latest, at offset, from offset, from time โข No Filter to apply upon reading โข Message Retention: 7 days โข Max throughput: 1 MB/s โข Max message size: 1 MB Oracle Cloud Infrastructure Listener OCI Streaming StreamPublisher On prem Listener Listener 3rd Party Cloud cursor OCI Streaming Service
- 13. EVENTS and STREAMING SERVICES
- 14. OCI Streaming Service โ DIY Push Oracle Cloud Infrastructure API Gateway Function Integration Cloud Function App Function Message Listener push OCI Streaming Stream OCI Monitoring Healthcheck Trigger Listener Function Function
- 15. Why and What a Katacoda Scenario for OCI Streaming? โข Introduce the OCI streaming service โข High volume publish/subscribe messaging platform โข Compatible with Apache Kafka & Kafka Connect โข Integration with other OCI services โ Events, Functions โข Get started Streaming through OCI CLI โข Create an OCI Stream โข Create a Function Listener โข Use OCI Monitor to check what is hapenning โข Expose functions via OCI API Gateway
- 16. NoSQL Database Cloud Service โข Launched in February 2020 โ a fully managed cloud service โข Based on Oracle NoSQL Database โข Which itself is based on Berkeley DB as storage engine โข Schemaless JSON and SQL enabled on relational data โข ACID, consistent, relational, structured, joins โข Partial JSON Updates โข Server-side updates to JSON documents โข Time-To-Live โ auto-expire on records โข Built-in Data Redundancy โข Multi-region architecture โข read-anywhere/write-anywhere in โWANโ cluster โข REST APIs, OCI CLI and SDKs in Java, Python, Node and Go
- 18. Why and What a Katacoda Scenario for NoSQL Database? โข Introduce the fully managed NoSQL Database Cloud service โข NoSQL Database is start small and cheap persistence solution in cloud native application architectures โข NoSQL Database is global, multi-model, ACID or BASE โข Introduce the OCI CLI for making a flying start with NoSQL Database service โข Create Tables โข Insert and Query relational records (OCI CLI & Console) โข Insert and Query JSON documents โข (partially) Update JSON documents โข Drop tables
- 19. Q&A and Live Handson Ask your questions in the Zoom Q&A Window Get your Cloud Trial: We will stay online for the next hour to help you out with handson challenges http://bit.ly/real-oci cloud.oracle.com/tryit
