Citrix ADC License

The licensed Citrix Application Delivery Controller or ADCs have received a lot of attention during the last decade with the aim of controlling the conditions related to the delivery of advanced applications and also improving their performance, along with the increasing demand for scalable appliances. ADCs are targeted networking tools whose task is to improve the performance, security and resiliency of web applications.

Application Performance

If the programs are not implemented according to the expectations of the users, their productivity will be greatly reduced. With the help of Citrix Application Delivery Controller(Citrix License), a set of mechanisms can be used to improve application performance, especially in mobile networks and high latency networks. Adjusting the SQL database load is one of the mechanisms for improving and developing its performance. This mechanism uses techniques used in TCP traffic load balancing, although this intelligence is applied at the database level. In this process, policy-based logic (Policy-Base) is used for each SQL transaction and improves the number of requests and connections created in the database cluster. Other services provided by the licensed Citrix Application Delivery Controller to optimize the normal performance of applications include the outsourcing of redundant server tasks, connection multiplexing, compression and caching. Considering that SSL and TLS are the main points of support for performing activities on the web and controlling encrypted traffic causes a large CPU load, the use of ADCs can handle a large volume of encrypted and unencrypted traffic. To control Additionally, Citrix Application Delivery Controller manages permissions and decrypts traffic before it reaches the server. TCP Multiplexing is an efficient and effective method to control a large volume of incoming requests to the server, which maintains active connections between the ADC and the server. When the traffic reaches the ADC, it routes the requests using these open channels, which eliminates the inefficient “Open-Close” overheads per transaction that can negatively affect server performance.

Optimizing performance in mobile networks

In addition to the above, ADCs have advantages in the performance of mobile networks. Often, the process of using web pages designed for high-speed Internet links is difficult for users who use mobile devices with limited bandwidth. To solve this problem, you can use the creative mechanisms of ADC. These mechanisms optimize the presentation of web content in mobile networks, including Domain Sharding. Connection-Layer optimization is usually applied to only one domain. The content of each page is divided into a sequence of subdomains, which allows more channels to open simultaneously, reducing page load times and improving performance. ADCs have the ability to see (Visibility) of the presented content and can optimize the process of presenting web pages with large images by converting GIF files to the more efficient PNG format. Another large component in web pages includes extended scripts and CSS files that ADCs can compress by removing unnecessary characters and whitespace. Due to the compression process, these files move faster on the network, and as a result, the download time is significantly reduced.

Application and user security

The web delivery process comes with new threats and vulnerability aspects that LAN-based applications never faced. Due to the fact that users are on the move more than before and need more access to programs and data, IT units of organizations must provide more solutions to protect data more accurately against external attacks and data leaks. The licensed Citrix ADC acts as an entry point or gateway in a network and authenticates each user’s action to access the program. If it is a SaaS-based program, ADC can verify the user’s identity by storing data on the existing Active Directory, in which case there is no need to store permissions in the Cloud. In addition to being more secure, this process improves user experience by enabling Single Sign-on for multiple applications.
