Introduction:
This is an article about Azure SignalR service.
It simplifies the process of adding real time web functionality to applications
over HTTP that allows the services to push content updates to connected
clients. The payload can be single page web or mobile application content
transfers updated without the need to pull the server or submit new HTTP
requests for updates in a way that allows for syncing of devices from a single
web server over HTTP. The devices can be connected to the server via the
control plane which represents those devices to the SignalR service as entities
to which it sends notifications. The scenario is one of synchronization or web
update and it is common to many applications and services where data is pushed
from the server to client in real time. The benefits cannot be overemphasized
when it concerns actions such as gaming voting polling or auction. The
dashboard and financial market data, sales update and multiplayer game
leaderboard can be maintained with this application It can support chat and
chatbot applications, real time shopping assistance, messengers and location
services. It is also very helpful towards targeted ads, collaborative
applications, push notifications and real time broadcasting or some other
scenarios in which Azure signal R service can be used. Finally, automation is a
core component in many workflows and that can also make use of triggers for
upstream events. The idea behind SignalR is the building of real-time web
applications using WebSocket which is an optimal transport for service and
events, and it avoids having the client pull for the server signal service. It
provides native programming experience with both asp.net core and asp.net. The
synchronization functionality of web servers can now be offloaded to its own
module but remain core component of web applications and services. Blazor is
used on the server side. This service
can be used with a wide range of clients spanning mobile applications to IoT
devices. The transport as well as its programmability with a variety of
languages makes it convenient to use and integrate with other clouds services
such as Azure functions and event grid. By itself or when used together with
other cloud scale traffic, it can scale to multiple instances and millions of
client connections. Switching to signal R service removes the need to manage
backplanes that handles scale and client connections at the same time. It also
provides compliance and security that Azure is known for. It's even possible to
utilize just Azure functions and SignalR without any web applications to build
service. Real time applications can be supported in multiple languages enabling
interoperability. Finally, SignalR features support a wide range of management
routines with respect to notifications and the clients that receive them.
Let’s compare this with a Do-it-yourself approach:
