Types
-
Event Grid Trigger
event routing services to build reactive, event-driven applications
Long Running
Durable Functions
-
-
runtime handles the state of management, checkpoints and restarts
-
mesaging technologies
event hubs
event Hubs will not process the next batch in a partition until the current batch, and every event in that batch, has completed.
provides message streaming through a partitioned consumer pattern in which each consumer only reads a specific subset, or partition, of the message stream
event grid
-
Event Grid is it is meant for processing events, not messages
Service Bus queue
-
Service Bus queues is an enterprise-grade message broker with some powerful features like sessions, managed dead-letter queues, and custom policies.
-
-
Message session state
to recover from unexpected failures and can resume partially completed work on a different process or machine from where the work began
partiotioning
when the topics, queues or messages need to be partitioned across multiple message brokers.
-
-
-
-
CosmosDB
query must include a filter on partition key, or it will need to be ran across multiple partitions
To use the MongoDB API, this must be configured at the Cosmos DB Account layer.
-
Unique keys
With unique keys, you make sure that one or more values within a logical partition is unique.
-
When a container has a unique key policy, Request Unit (RU) charges to create, update, and delete an item are slightly highe
Cost are charged by Request Units (Operation of read, change or delete in one container)
High Availabilty
Multi Region replication
Multi-Region Writes
AKA: Multimaster, Active -Active

Availabilty Sets (AS)
Moves
-
-
-
-
Virtual machines deployed to an availability set must use the same resource group as the availability set itself.
Virtual machines deployed to an availability set must be deployed to the same region as the availability set itself.

-
AddVM
To add another virtual machine, it needs to be in the same region and resource group as the availability set

High Abylability
auto-failover groups
-
inclusion of DNS for both the primary read/write endpoint, and the secondary read endpoint
reduces the management overhead for ensuring applications are pointing to the correct resources in the event of a disaster.
supports replication, and failover, for one or more databases on Azure SQL Database, or Azure SQL Managed Instances
