WebAssembly
hosting model benefits
The Blazor WebAssembly hosting model offers
several benefits:
Ø There's
no .NET server-side dependency means server connection not required.
Ø Client
resources and capabilities are used.
Ø Workload
is from the server to the client.
Ø For
hosting the application we don’t need any host app even we can host on our
host(for example, serving the app from azure or a CDN).
There are downsides to Blazor WebAssembly
hosting:
Ø The
app is restricted to the capabilities of the browser.
Ø Capable
client hardware and software (for example, WebAssembly support) is required.
Ø Download
size is larger, and the very 1st request apps take longer time to
load.
Blazor
Server hosting model benefits :
The
Blazor Server hosting model offers several benefits:
Ø
Download size is smaller than a Blazor WebAssembly the app, and the application loads much faster.
Ø
The app takes full advantage of server capabilities.
Ø
.NET Core on the server is used to run the app, so
existing .NET tooling, such as debugging, works as expected.
Ø
Blazor Server apps work with browsers that don't
support WebAssembly. There are downsides to Blazor Server
hosting:
Ø
Higher latency usually exists because of the roundtrip of
server.
Ø
There's no offline support. If the client connection
fails, the app stops working.
Ø
Scalability is challenging for apps with many users.
Ø
An ASP.NET Core server is required to serve the app.
