Here is a list of top providers of CDN:-
1. Akamai
Akamai is known globally to speed up networks and connections. They have a strong infrastructure to speed up sites and make things better for online users. Of course, this company works with big brands and large business in general.
It is the leading CDN provider, which helps webmasters maintain a fast webpage loading by distributing content from locations close to the readers. It delivers excellent website performance for highly interactive content, including HTML, CSS, audio, graphics, animation, and video by transparently mirroring content. Besides, it delivers secure online date transfer through SSL-content protection, thus reducing the risk of load-based online attacks.
Lets try to understand CDN by an example:
When we type in a web address like www.google.com, our browser is actually asking Google’s servers to send back all of the resources needed to display that page. That includes things like the code to position search results, to manage what happens when you run a new query and whatever the latest flavor of their logo is. All of those things have to be downloaded over wires that can run for quite a long distance. A CDN is a transparent way to physically move many of the resources of a webpage closer to our computer.
Performance will not cost you a bomb with our Festive Server Plans! These plans are designed to suit your requirements, with bundling of various flavors of Web Hosting, Re-seller Hosting & VPS.
Web Application Firewall (WAF) is the firewall which filter, Monitor and blocks the HTTP traffic to and from the web application. WAF is different from the system regular firewall because regular firewall provides the safety gates between the server while the WAF filter the content of the web application. It protect the web application by controlling the input and output and access to and from the web application. When we apply WAF on any web application it inspect every HTML, HTTPS, SOAP and XML data packet. Basically WAF is used to prevent from the HTTP attacks such as cross site scripting(xss), sql injection etc.

There are three user based permission groups for each file and directory:-
To add a user in linux:-
# useradd <user-name>
This command is used to add a user in linux. A root user is the superuser in the linux. So a root user only have the right to add another user. Another user can only add a user if the root user give access to do it so.

The Wireless Charging (also known as Inductive Charging) is now-a-days a new trending technology. Many companies are offering wireless gadgets which offer good performance.
The Wireless Charging uses electromagnetic to safely transfer power from transmitting host to the recieving device for the purpose of charging a battery.
Wireless charging is based on the principle of magnetic resonance, or Inductive Power Transfer (IPT). This is the process of transferring an electrical current between two objects through the use of coils to induce an electromagnetic field.
Linux is the most powerful and popular OS in the world. It is a open source source software. The code used to create linux is free and also available to view, edit and especially for the users who have appropriate skills can contribute to it. It is widely used in the IT industry these days. It provides better security with respect to other OS in the market. Linux runs on most of the devices in the world. The chances of getting virus in the linux OS is very less as compared to other OS such as Windows or MAC.
It defines a group of one or more worker processes, configured with common settings that serve requests applications that are assigned to that application pool. It allow a set of Web applications to share one or more similarly configured worker processes and provide a convenient way to isolate a set of Web applications from other set of Web applications on the server computer. In it there is are process boundaries which separate each worker process and because of this reason application problems in one application pool do not affect Web sites or applications in other application pools.
As you may have read in the media recently, a new zero-day security vulnerability for a common component in the Linux operating system has been released into the wild. This vulnerability allows attackers to remotely access some vulnerable Linux-based systems without the use of compromised passwords or other user credentials. Once in the system, attackers could leverage other vulnerabilities to escalate privileges until they gain root access. A good article that describes the vulnerability can be found here:
