Application deliveries provide the appropriate levels of availability, security, visibility, and acceleration to applications. These application delivery networking technologies feature their own proprietary CPUs and generally reside at the network endpoints.
What is an Application Delivery Controller?
ADC has become one of the most essential components in any datacenter today, we live in a dynamic world and number of applications is increasing every single day to help us do our job or shop online, to manage our finance with online banking or play online games with friends, our social media applications that we access it all the time.
If we look around today, we will understand that applications became a big part of our daily lives and helping us in so many levels in both business and personal purposes.
How would these applications serve us?
In order to serve your customers, you will have to make sure that your application is available 24/7, but with availability comes the risk of security, how to make sure that my application is available and security? Below, we explain how ADC helps your applications achieve this goal.
Availability means that the application must be available all the time no matter what happens, ADC will act as the mand in the middle between your applications and the internet. Any request come to the applications will be intercepted and handled by the ADC so the internet user will not be able to have visibility or access to the actual application.
But what if something went wrong with your ADC? Therefore, it is always recommended to have high availability, means that you must have two or more ADC devices configured as active/active or active passive. So when something goes wrong with one of these devices, other devices will take control automatically with zero downtime.
The second important thing the ADC provide is acceleration, set of features which will help your application to perform better. Such as:
- RAM Caching.
- HTTP compression
- TCP optimization
- SSL offload
It is great to make your application available all time with high performance, but if its not secured, hackers could easily take it down!
Therefore, application delivery controllers offer security features to protect your applications from different types of attacks such as:
- Web Application Firewall
- DDOS mitigation
- SSL Interception
- Single Sign-On
- DNS Protection and more…
