1. Ashish Chhabria Service Bus update Program Manager - Microsoft
Hello everyone, my name is Ashish Chhabria and I’m a Program Manager for the Azure Messaging team focusing on Azure Service Bus!

2. What is Service Bus?
Fully managed PaaS offering - “Enterprise Messaging as a Service”.
Point to Point (Queue) and Pub-Sub (Topic-Subscription) semantics.
Central arbiter of state / truth of transition or ownership.
You know the nouns:
Who is sending the message?
What is the message?
Where is the message being sent?
Hello everyone, my name is Ashish Chhabria and I’m a Program Manager for the Azure Messaging team focusing on Azure Service Bus!
So, what exactly is Service Bus?
It is our fully managed PaaS offering that offers Enterprise Messaging at scale – “Enterprise Messaging as a Service” if you will.
We support both Point to point as well as Pub/Sub semantics via Queues and Topics-Subscriptions respectively.
Service Bus can be thought of as a central arbiter of state and ownership – moving money or matter between 2 disconnected services, allowing your business logic to decouple and scale horizontally as needed.
The broader messaging team offers different solutions to various problems, but if you know the “nouns” in your use-case, Service Bus is probably the best tool for you.

3. Service Bus - Queues Sender sends message to queue Queue ACKs receipt
Receiver connects to queue & retrieves message
Receiver ACKs complete (or other action)
I want to set the context on the Queue and Topic/Subscription semantics.
Here the queue decouples the sender and the receiver.
Both are aware of the queue and interact with the queue and the queue ACKS receipt on the sender side as well as the complete on the receiver side.
Sender
Receiver
Queue

4. Service Bus - Topics & Subscriptions
Sender only knows about Topic
Receivers only know about Subscriptions
Filters and Actions exist on Subscriptions
type=order
Filter
Subscription 1
“type” = “order”
Topic
On the Topic-subscription side,
The sender is aware only of the topic, while the receiver is aware of the subscription only.
When a message is sent to a topic and it satisfies multiple filter conditions, the message is duplicated across those subscriptions.
type=quote
“type” = “quote”
Subscription 2
Filter

Business Continuity
Enterprise Features
Clients & Connectors
So….
What has the team been upto?
We’ve got a bunch of new features and improvements to talk about – and I’ve grouped them based on the below 3 themes.
Let’s first look at our Business Continuity offerings.

8. Business Continuity – High Availability & Disaster Recovery
Business continuity incorporates all our efforts for high availability, disaster recovery and enabling you to achieve those goals.

9. Global Expansion and Availability Zones
Azure Service Bus is now available in 50 Azure regions!
Azure Service Bus now has “Availability Zones” in all compatible regions.
So, this is great.
Firstly, Azure Service Bus got upgraded to a “core” service, so it will be among the first services to launch in any new data center.
On that note, it is now available in all 50 public Azure Regions.
Additionally, Azure Service Bus also has “Availability Zones” support in all compatible regions.

10. Availability Zones
Fault tolerance for Service Bus Premium namespace within the same datacenter region.
3 copies (Primary + 2 secondary) are stored across different datacenters in the same region.
In case of datacenter failure, one of the secondary copies becomes the primary, *automatically*.
Primary
Secondary
Availability Zones enables fault isolation within the same data center region.
For our Service Bus Premium namespace, we provision 3 copies of the backend – i.e. 1 Primary + 2 Secondary copies.
When Availability Zones are enabled, these 3 copies are distributed across different data centers within the same region, separated by miles.
If the primary goes down, one of the secondary copies is automatically promoted to Primary.
All this is abstracted away from the client applications.s
Secondary

11. Geo-Disaster Recovery
Fault tolerance across different datacenter regions for Service Bus Premium namespace.
2 separate premium namespaces are provisioned and paired.
Metadata is always in sync.
Failover is managed by the customer.
Disaster Recovery with full data copy will follow!

12. This is great! But, how do I upgrade my Standard namespace to use these features?
Premium

13. In-place upgrade for Service Bus Standard
Enables migration of existing Service Bus Standard namespace to Premium.
A new premium namespace is created and linked to the Standard namespace.
Metadata (Queues, Topics, Subscriptions) is copied over from the Standard namespace to Premium namespace.
On completion, Connection string becomes an alias for the new Premium namespace.

14. Enterprise Features
Next up, we have Enterprise features !

15. Virtual Network Service Endpoints & Firewalls
Limit access to your namespace from specific Virtual Networks or IP address/s
Virtual Network ACL
The first offering is the VNET service endpoints and Firewalls.
Here we enable you to limit access your namespaces from specific virtual networks or IP address ranges, even if other client machines have the connection string to connect to the namespace.
We have tooling available for PowerShell/CLI and ARM templates, but I’ve got the portal screenshot here for a simple example.
Here you can add your existing Virtual Networks to your ACL to protect your service endpoints within those VNETs.
Alternatively, you can also add specific IP addresses or ranges to the Firewall ACL.
Any incoming request is first validated against the VNET ACLs, and if rejected on the VNET ACLs, it is validated against the Firewall ACLs.
Firewall ACL

16. Managed Service Identity and RBAC
Currently in Preview – GA by July 2019!
Register your application with
Full Data/Management access via built-in “Azure Service Bus Data Owner” role
Custom roles per your use-case
Insert configuration into App.config file for your application.

{/}
The next feature is MSI and RBAC.
This feature is currently in preview and we’re working towards GA-ing this by early next month.
With this feature, you no longer have to worry about Connection strings, SAS keys and the like – you can simply use Azure Active Directory to create a Service Identity and assign it a role.
Once assigned, you can configure your application with the same data.
You can choose either the built-in role that grants full data and management access – this is called “Azure Service Bus Data Owner”.
Or you can create your own role as well.

17. Clients and Connectors
Next, we’ll talk about our SDK Client and Connectors effort.

18. Client SDKs Node.js – Generally Available! Java and .NET
Management Client
Web sockets support
Transactions support
Python – coming soon!
