Introduction

As mentioned previously, Active Directory is a process consisting of three different components: Domain, Trees and Jungle. Domain allows Active Directory objects to be grouped into separate groups according to their purpose and function. These groups, which are grouped under the domain, are combined to form trees, and forests that are assembled to form these trees . In trees, each domain group is organized in hierarchy, with the level of access to authority and network resources. For example, AD object 2 may not have the same network access as AD object 15. This set of AD objects is best known under the Organizational Units (OU) domain. In this article we explore more about Active Directory Domain Services with Microsoft Development Services.

Active Directory Domain Services (ADDS)

Since the domain is an important part of Active Directory, it provides Active Directory Domain Services (AD DS). As the name suggests, it helps manage Windows servers. This is one of the most substantial services as it records information and data about the interaction between the user and the domain. In the app, when a person tries to log into the website, AD DS thoroughly checks the user's credentials and passwords and then assigns the defined network resources available to that user with Microsoft Consulting Chicago.

Advantages of Active Directory Domain Services



This service provides a second level of protection to the network and prevents any crossover between domains.

This service allows IT professionals to efficiently assign and delete rights and resources to employees or to other AD objects that are included in the Active Directory.

Although it does not play an important role in ensuring cyber security, it does increase efficiency Single Sign-On (SSO) capabilities that it provides.

This service allows employees to switch from one server to another to access other resources without having to enter their user credentials each time, which is more time consuming. Thanks to the domain controller that powers this locomotion for the user.

Restriction on Active Directory Domain Services

It is important to realize that many AD objects do not work together under a particular domain structure. This is a management boundary and allows only objects belonging to a single OU to be configured and managed together. This makes it easier for IT administrators to perform tasks when working with multiple OUs.

What are Restful Web Services

Introduction

In our previous article we discussed what is API. There are different types of API calls, such as Simple Object Access Protocol (SOAP), Remote Procedure Call (RPC) and Representational State Transfer (REST). All of these API calls have the same purpose i.e. to securely transfer data between two or more systems. In this article we will explore only the restful web services.

What is REST

As mentioned earlier, REST is a representational state transfer. It is a simple way of sending and receiving data between client and server. No software or standards are required to transfer data. It has a predefined structure to call the API. Developers need to use a predefined path and pass their data into a JSON payload.

Properties of Restful Web Services

A RESTful web service has the following six restrictions / attributes:

Client-Server: This is a very important component of REST APIs. A REST API follows the client-server architecture and must be separate. This means that both the server and the client cannot be the same server. If this is the same, you will receive a CORS error.

Stateless: In REST, all calls are treated as a new call and any previous call state does not give any benefit to the new call. So during each call, all required authentication and other information needs to be handled.

Cache: A REST API promotes the browser and server caching process to speed up its processing.

Uniform Interface: The interface between client and server is homogeneous, so any changes on both sides will not affect API performance. It helps develop client and server systems independently.

Layered system: REST allows the use of layered structure on the server side which means that you can have data on a different server, the authentication on a different server while the API is on a different server. The client will never know which server is receiving the data.

Code on Demand: This is an optional feature of the REST API that can also send executable code to the server client that runs directly at run time.

Methods in Restful Web Services

Using Restful Web Services, we can perform four basic operations:

Get: This method is used to get a list of data from the server.

Post: This method is used to post / create a new record on the server.

Put: This method is used to update the existing record of the server.

Delete: This method is used to delete a record on the server side.

NOTE: Calling the above method does not guarantee that operations will be performed until these operations are executed on the server side as well.
