- 1Azure Service Fabric
- 2Programming Models for MicroServices-Reliable Services
-Reliable Actors - 3What are "Reliable Services"?Light-weight framework for writing
services that integrate with the Service Fabric platform and benefit from the full set of platform features:
->Reliability
->Availability
->Scalability
->Consistency
https://docs.microsoft.com/pt-pt/azure/service-fabric/service-fabric-reliable-services-introduction - 4What are "Reliable Actors"?Built on top of Reliable Services, the Reliable Actor framework implements the Virtual Actor pattern, based on the actor design pattern
https://docs.microsoft.com/pt-pt/azure/service-fabric/service-fabric-reliable-actors-introduction - 5MicroService Issues->Some services can be coded in only a few lines of code
->Some services are called infrequently
->The load of some services can change very fast - 6What are Cloud Functions?Cloud functions are small pieces of code, written in a high-level language.
Cloud function are invoked when some event occurs – such as loading an image into cloud storage, receiving a read of a
sensor, etc. - 7Key differences between "stateless" and "statefull"?Decoupled computation and storage: The storage and computation scale separately and are provisioned and priced independently.
Automatic resource allocation
Paying in proportion to resources used instead of for
resources allocated. - 8Key Components of FaaS->Virtual Machines and Containers for fast provisioning and strong security
-> “warm pool” of VM instances that need only be assigned to a tenant;
-> “active pool” of instances that have been used to run a function before and are maintained to serve future invocations. - 9Azure Function Triggers-> HTTPTrigger
->TimerTrigger
->CosmosDBTrigger: Process Azure Cosmos DB documents when
they are added or updated
->BlobTrigger - Process Azure Storage blobs when they are
added to containers.
->Respond to events delivered to an Azure
Event Hub, such as in application instrumentation, and
internet-of-things (IoT) scenarios.
