- 1. Serverless in the Azure World Kasun Kodagoda Technical Lead | 99X Technology https://kasunkodagoda.com
- 2. I am, Kasun Kodagoda • In ♥ with Azure & Azure DevOps • Active Blogger – https://kasunkodagoda.com • Open Source Contributor - https://github.com/kasunkv • Technical Lead I Work For, • Established in 2004 • Headquartered in Sri Lanka with offices in Europe and Australia • Providing high quality, high value Software Product Engineering + R&D services
- 3. What is Azure? • A complete cloud platform • Host existing applications/services • Host new applications/services • Enhance On-Premise applications/services • Easy to Scale • High availability • Easily manageable services • Many ways to manage Azure Services • Including the Azure Portal, CLI, REST APIs etc.
- 4. Types of Azure Services Infrastructure as a Service (IaaS) Platform as a Service (PaaS) Serverless Customer Managed Platform Managed Code Only
- 5. Catalog of Azure Services Compute Networking Web & Mobile IoT & Enterprise Integration Development Services Intelligence & Analytics Databases Storage Monitoring & ManagementSecurity & Identity
- 6. Azure Regions • Azure is a global cloud platform • Available in many geographical regions • Create your resources in any region • Run your apps closer to your customers • Conform to legal requirements • High availability with multi-region apps Not all resources are available in all regions
- 8. Azure Serverless Offerings Azure FunctionsAzure Logic Apps Azure Event Grids
- 10. Azure Logic Apps • Great for workflow automation • Business workflows • Operations workflows • Designer First Experience • Visually design workflows, No coding needed • If you want, you can use JSON to code your logic apps • Hundreds of Connectors at your disposal • Integrate, Interact with enterprise services • Triggers and Actions • Create custom connectors if you want
- 11. Azure Logic Apps • Pay-As-You-Go Pricing Model • Pay for only what you use • Different pricing for each connector types (e.g. Standard, Enterprise) • Fixed Pricing Model • Integrated Service Environments (ISE) • Fixed monthly prices • Different ISE tiers to select from
- 13. Azure Event Grids • Great for Event-Based applications • Serverless event routing • Reacting to events from Azure Resources, Customer event publishers etc. • Event Sources • Where the events happen • E.g. Blob storage, Azure Maps, Resource Groups etc. • Event Handlers • Where the event is sent by event grids • E.g. Azure Functions, Logic Apps, Azure Automation etc.
- 14. Azure Event Grids • Simple to use • Point and click to send events from your azure resource to handlers • Advanced Filtering capabilities • Select which event types go to what event handler • Reliable service • Exponential back-off up to 24hr to make sure events are delivered • Can handle high volume of events • Pay-Per Event • Pay-as-you-go model • 100,000 operations free
- 17. + = Code Events + Data Azure Functions
- 18. Azure Functions • Simplified Programming Model - Write the code to respond to an event - No need to write setup code - Write code for only what you need to do - Focus on the business logic • New Pricing Model - Pay only for what you use, No more - If you are not using, you are not paying - Consumption Plan - Pay as you Go - App Service Plan - Use Already existing App Service Plan
- 19. Azure Functions • Consumption Plan - Pay as you Go - Uses 2 metrics to measure resource usage - Number of Executions - CPU Time x RAM Usage (Giga Byte Seconds GB-s) - CPU Time in seconds (s) - RAM Usage in Giga Bytes (GB) - Free monthly grant provided - 1 Million Executions - 400,000 GB-s * Function execution is limited for 5 minutes for execution. You can also set daily quota in GB-s
- 20. Azure Functions • App Service Plan - Already existing App Service Plan - Dedicated Pricing Model for Functions - Predictable monthly cost - E.g. If you already have powerful VMs - Run like normal Web or API App * Does NOT have the 5minute execution limitation.
- 21. Azure Functions • Triggers - Defines the invocation of the function - Must have exactly one trigger - A trigger has some associated date with it - Remember, Events + Data - Contains the payload that triggered the functions - Easy to configure triggers - Use the UI provided in the portal - Update the functions.json file manually
- 22. Azure Functions • Bindings - Means of connecting to data from the code - 2 types of bindings - Input Bindings - Output Bindings - Bindings are optional - Can have multiple input and output bindings - Easy to configure bindings - Use the UI provided in the portal - Update the functions.json file manually
