  What SQL Databaseneeds

  What SQL Databaseneeds SQL Database is Database as a Service It is only the database Vs. SQL20xx Almost language syntax aligned Deprecated features Migrate features to External/Other Azure Services Overlapping features (ex. JSON)

  Serverless as glue
• 7.
  Choose your abstraction
• 8.
  Serverless manifesto Function arethe unit of deployment and scaling. Scales per request Users cannot over- or under-provision capacity. Never pay for idle (no cold servers/containers or their costs) Trigger-based invocation code run because of an event happened and has to be handled
• 9.
  Serverless as abridge for SQL Databases Import/Export Other data formats Data manipulations Schedules Other Azure services bridges

  What is AzureServerless A serverless nirvana? Microsoft Azure CTO Mark Russinovich on the future of the cloud https://www.geekwire.com/2017/serverless-nirvana-microsoft-azure-cto-mark-russinovich-future-cloud/

  Functions
• 12.
  Azure Functions Process eventswith Serverless code. Make composing Cloud Apps insanely easy Develop Functions in C#, Node.js, Python, PHP, Batch and more Easily schedule event-driven tasks across services Expose Functions as HTTP API endpoints Scale Functions based on customer demand
• 13.
  Azure Functions architecture AzureFunctions is built around the WebJobs SDK runtime. The WebJobs SDK makes it easy to react to events and work with data in a consistent abstracted fashion.
• 14.
  Platform and scaling AppService offers dedicated and consumption tiers. Dedicated is the existing App Service plan tiers Basic, Standard, Premium Pay based on # of reserved VMs You’re responsible for scale Consumption (Dynamic) Pay per execution model - two meters, three units Number of executions Duration of execution x reserved memory

  Durable Functions Enable “longrunning” functions while maintaining local state. Simplify complex Function coordination (chaining, etc.) Easily call a Function from another Function All of the above using code- only
• 20.
  Functions and LogicApps Functions and Logic Apps work great together and that integration will only get better. You can orchestrate Functions using Logic Apps today. Durable Functions overlaps with Logic Apps, one function calling another, but: -Offers advance ‘code only’ orchestration ‘like’ capabilities to function -Enables "long running" functions -Enables "advance" scenarios/patterns which are difficult otherwise: async HTTP, map reduce, actors, etc.

  Logic Apps
• 22.
  Shared with Functions Serverless AppService based Triggers (templated)
• 23.
  Unique for LogicApps «Older»/Mature(?) Implement and orchestrate visually designed integration workflows Orchestrate distributed microservices Or Functions Every action is a an http endpoint Connectors Declarative No code designer for rapid creation (mostly?)
