انواع driver شبکه و موارد استفاده آن در docker

Bridge Network Driver

The bridge networking driver is the first driver on our list. It’s simple to understand, simple to use, and simple to troubleshoot, which makes it a good networking choice for developers and those new to Docker. The bridge driver creates a private network internal to the host so containers on this network can communicate. External access is granted by exposing ports to containers. Docker secures the network by managing rules that block connectivity between different Docker networks. 


Overlay Network Driver

The built-in Docker overlay network driver radically simplifies many of the complexities in multi-host networking. It is a swarm scope driver, which means that it operates across an entire Swarm or UCP cluster rather than individual hosts. With the overlay driver, multi-host networks are first-class citizens inside Docker without external provisioning or components. IPAM, service discovery, multi-host connectivity, encryption, and load balancing are built right in. For control, the overlay driver uses the encrypted Swarm control plane to manage large scale clusters at low convergence times. 


MACVLAN Driver

The macvlan driver is the newest built-in network driver and offers several unique characteristics. It’s a very lightweight driver, because rather than using any Linux bridging or port mapping, it connects container interfaces directly to host interfaces. Containers are addressed with routable IP addresses that are on the subnet of the external network.

As a result of routable IP addresses, containers communicate directly with resources that exist outside a Swarm cluster without the use of NAT and port mapping. This can aid in network visibility and troubleshooting. Additionally, the direct traffic path between containers and the host interface helps reduce latency. macvlan is a local scope network driver which is configured per-host. As a result, there are stricter dependencies between MACVLAN and external networks, which is both a constraint and an advantage that is different from overlay or bridge.

RavenDB؛ تجربه متفاوت از پایگاه داده
توضیحات بیشتر در اینجا
By default RavenDB allow anonymous access only for read requests (HTTP GET), 
and since we creating data, we need to specify a username and password. 
You can control this by changing the AnonymousAccess setting in the server configuration file.
Enter your username and password of your Windows account and a sample data will be generated for you.

مقاله درباره ViewModel

Use ViewModels to manage data & organize code in ASP.NET MVC applications
The concept of the ViewModel isn't just for ASP.NET MVC, as you'll see references to ViewModels throughout the web in articles and blog posts about the MVC, MVP, and MVVM patterns. Those posts and articles can center around any number of technologies such as ASP.NET, Silverlight, WPF, or MVC... This post will investigate ViewModels as they apply to the world of ASP.NET MVC.

بررسی imageهای مختلف NET. در Docker

.NET and .NET Core (and Windows!) have been getting better and better with Docker. I run Docker for Windows as it supports both Linux Containers and Windows Containers. They have both a Stable and Edge channel. The Edge (Beta) channel is regularly updated and, as a rule, gets better and better in the year I've been running it.

چگونگی مستندسازی اشیای Microsoft SQL Server

In any good programming reference, you will read that a developer has to document his code, not only for him/herself, but also for the person who, ten years later will be asked to maintain it. This would, of course, be made easier thanks to a good documentation of existing code.

ویژگیهای برنامه ریزی شده C# 8.0

In this C# 8 tutorial, I am going to introduce a selection of currently planned features which will most probably end up in the final release. All of the C# 8 features are still early in development and are likely to change.

مدیریت مباحث همزمانی مرتبط با یک Rich Domain Model با استفاده از EFCore و الگوی Aggregate

In summary, the most important issues here are:

  • The Aggregate’s main task is to protect invariants (business rules, the boundary of immediate consistency)
  • In a multi-threaded environment, when multiple threads are running simultaneously on the same Aggregate, a business rule may be broken
  • A way to solve concurrency conflicts is to use Pessimistic or Optimistic concurrency techniques
  • Pessimistic Concurrency involves the use of a database transaction and a locking mechanism. In this way, requests are processed one after the other, so basically concurrency is lost and it can lead to deadlocks.
  • Optimistic Concurrency technique is based on versioning database records and checking whether the previously loaded version has not been changed by another thread.
  • Entity Framework Core supports Optimistic Concurrency. Pessimistic Concurrency is not supported
  • The Aggregate must always be treated and versioned as a single unit
  • Domain events are an indicator, that state was changed so Aggregate version should be changed as well  
public class AggregateRootBase : Entity, IAggregateRoot
{
    private int _versionId;

    public void IncreaseVersion()
    {
        _versionId++;
    }
}
internal sealed class OrderEntityTypeConfiguration : IEntityTypeConfiguration<Order>
{
    public void Configure(EntityTypeBuilder<Order> builder)
    {
        builder.Property("_versionId").HasColumnName("VersionId").IsConcurrencyToken();
 
        //...
    }
}
var order = await _ordersContext.Orders.FindAsync(orderId);
order.AddOrderLine(request.ProductCode); 
var domainEvents = DomainEventsHelper.GetAllDomainEvents(order);
if (domainEvents.Any())
{
    order.IncreaseVersion();
}
await _ordersContext.SaveChangesAsync();
