IIS 8.0 Hosting UK - HostForLIFE.eu :: Discover gRPC's Protocol Buffers

clock November 21, 2024 06:59 by author Peter

What are Protos?
The high-performance RPC framework called gRPC relies heavily on protos, which are an acronym for protocol buffers. They are a method of defining and sharing structured data that is independent of language. Prototypes basically act as a template for serializing and deserializing data so that the client and server can comprehend and communicate with each other.

Importance of Protos

  • Contractual Agreement: Protos serve as the client and server’s contract. In order to avoid misunderstandings and guarantee compatibility, they specify the precise structure and kinds of data that will be transferred.
  • Code Generation: gRPC can produce client and server stubs in a number of programming languages, including C++, Java, Python, and Go, once a proto file has been specified. Error risk and development time are greatly decreased as a result.
  • Platform Independence: Because prototypes are language-neutral, they can be utilized on a variety of platforms and programming languages. Because of this, gRPC is extremely flexible and adaptive to many settings.
  • Efficiency: Compared to text-based formats like JSON or XML, the binary serialization format used by gRPC is typically more efficient.1. Faster communication and less network overhead are the outcomes of this
  • Evolution and Versioning: Since prototypes support versioning, you can change your data structures over time without upsetting current users. Upholding compatibility and supporting updates require this.

Why You Should Know About Protos Before Starting with gRPC?

  • Understanding gRPC’s Core Concepts: One of the main components of gRPC is the proto. You won’t be able to understand the fundamental ideas and make good use of the framework if you don’t have a firm grasp of protos.
  • Defining Services and Messages: Protos are used to define gRPC services and the messages that will be exchanged between those services. Knowing how to write Protos is essential for designing your gRPC architecture.
  • Generating Client and Server Code: As mentioned earlier, gRPC generates client and server stubs from protos. Understanding protos will enable you to customize the generated code to your specific needs.
  • Efficient Data Transfer: Protos’ binary serialization format can significantly improve the performance of your gRPC applications. Knowing how to optimize your protos can lead to more efficient data transfer.

A Basic Proto Example
Here’s a simple example of a proto file defining a greeting service.
syntax = "proto3";

service GreetingService {
  rpc SayHello (HelloRequest) returns (HelloReply);
}

message HelloRequest {
  string name = 1;
}

message HelloReply {
  string message = 1;
}

This proto file defines a GreetingService with a single method, SayHello. The HelloRequest and HelloReply messages specify the structure of the data that will be exchanged.



IIS Hosting UK - HostForLIFE.eu :: How do You Publish ASP.NET Core 9 on IIS (Internet Information Service)?

clock November 15, 2024 08:21 by author Peter

In this article, I presume you already have a pool on your Windows Server IIS. Follow the steps to understand the tricks for publishing ASP.NET Core 9 applications under IIS environments.

You need to set up your code to support IIS and configure the project to run on the architecture from the target pool. To check if your pool is running on x86, verify the inetmgr console, verify the Advanced setting... and check if Enable 32-Bit applications are set to true.

Let's do the steps to publish
Step 1. Start your new ASP.NET Core MVC.
dotnet new mvc -n MyTestApp

Step 2. If you compile the application and start publishing, you face these default parameters.

Step 3. I tried to publish it but got an error of 503. It's normal. This is what we will fix.
Step 4. Open the solution configuration, and choose New... from the Active solution platform.
Step 5. Choose your architecture pool. It should be the same as the pool on IIS (x86 for 32 bits).

Step 6. It will look like this.

Step 7. Back to the Publish configuration, you need to change this.

Step 8. But you will get the same error if you try to publish.

Step 9. To fix this, you need to configure your application to run under Windows, adding <TargetFramework>net9.0-windows</TargetFramework>, unload the project and edit it.
<Project Sdk="Microsoft.NET.Sdk.Web">
  <PropertyGroup>
    <TargetFramework>net9.0-windows</TargetFramework>
    <Nullable>enable</Nullable>
    <ImplicitUsings>enable</ImplicitUsings>
    <Platforms>AnyCPU;x86</Platforms>
  </PropertyGroup>
</Project>

Step 10. Now, if you open the Properties of your application, you will see that it is enabled to Target OS version 7.0.

Step 11. Now, you need to select the c: with "net8.0-windows":

Step 12. Before publishing a dotnet, copy the file app_offline.htm to the target IIS installation folder. This turns off the website so this message is displayed if you try to use it:


Step 13. Extra source code, Microsoft default source code. If the file name app_offline.htm indicates to dotnet that the execution should be terminated, it automatically redirects to it. You can customize this file as you like.
<!doctype html>
<title>Site Maintenance</title>
<style>
   body {
   text-align: center;
   padding: 150px;
   font: 20px Helvetica, sans-serif;
   color: #333;
   }
   h1 {
   font-size: 50px;
   }
   article {
   display: block;
   text-align: left;
   width: 650px;
   margin: 0 auto;
   }
   a {
   color: #dc8100;
   text-decoration: none;
   }
   a:hover {
   color: #333;
   text-decoration: none;
   }
</style>
<article>
   <h1>We&rsquo;ll be back soon!</h1>
   <div>
      <p>Sorry for the inconvenience but we&rsquo;re performing some maintenance at the moment. We&rsquo;ll be back online shortly!</p>
   </div>
</article>

Step 14. You may face an error 503 yet, so add <AspNetCoreHostingModel>OutOfProcess</AspNetCoreHostingModel> to run OutOfProcess.
<Project Sdk="Microsoft.NET.Sdk.Web">
   <PropertyGroup>
      <TargetFramework>net9.0-windows</TargetFramework>
      <Nullable>enable</Nullable>
      <ImplicitUsings>enable</ImplicitUsings>
      <Platforms>AnyCPU;x86</Platforms>
      <AspNetCoreHostingModel>OutOfProcess</AspNetCoreHostingModel>
   </PropertyGroup>
</Project>

Step 15. Copy the files, then delete the app_offline.htm file to run the application. This is the result.




IIS 8.0 Hosting UK - HostForLIFE.eu :: How to Configure Authentication for the Virtual Directory?

clock November 1, 2024 08:47 by author Peter

Introduction
In this article, you will learn about how to configure authentication for the Virtual Directory.

Step 1. First of all, open the Administrative Tools from the Start Menu.

In the Administrative Tools Wizard, an option named IIS Manager will be available; double-click on this option to open it.


Step 2. Now, the IIS Manager Wizard will be opened; here, on the left-hand side, the Connections Pane will be available. The Connection Pane will show your Server Name.

Expand your Server's Name. Now you will see a folder named Sites, which contains all the sites that you have configured on IIS.

Step 3. Expand this folder to see the Configured Sites and their Virtual Directories.


Now click on the site on which the authentication process is to be performed and expand it. Under this site, you will find the Virtual Directory that you have already created.

Step 4. In the Features View, an option named Authentication will be available; double-click on it to open it.

Now your Authentication Wizard will be opened, here you will see that many types of Authentications are available.

Step 5. Right-click on any of the Authentications, and you will then see that you can Enable, Disable, or Edit the Authentication from here, if you want to Disable or Enable any of the authentications then click on it.

On clicking the Edit button, you will see that you can provide the User Name for the Anonymous User Identity.

Follow the same process for all types of authentication.
