13. Web Application Delivery Challenges So why is there such high demand for a solution that optimizes the delivery of web applications? Several recent trends have converged to create a �perfect storm� for the IT managers tasked with delivering web apps: [Click] To begin with, IT organizations are consolidating data centers to reduce costs and simplify management. This moves applications further away from end users, increasing the distance application traffic must travel before it reaches its destination. [Click] At the same time, application users are increasingly mobile, moving further away from the datacenter and accessing applications via a wider variety of devices and network connections. This exacerbates the situation, resulting in increased latency, greater packet loss and overall stability problems. [Click] To make matters worse, applications delivered over the Web use extremely �chatty� protocols like HTTP which generate a lot of back-and-forth �hand-shaking� traffic between the server and the client. Applications that may have generated a few hundred connections a day in the client-server world can now generate thousands of connections per second as a web app. The further away the user is from the datacenter, the more these round-trip transactions slow down overall response time. Emerging Web application development practices such as Ajax exacerbate this problem, since they frequently take what used to be a single request, and break it into a series of much smaller requests. The net effect is more requests on the wire. [Click] And last but not least, mission-critical web applications must be subjected to far more security policies today than ever before to ensure that confidential data is never compromised. Hackers have evolved. Attacks are no longer about defacing websites. The majority of attacks today are at the application layer and are designed to steal valuable corporate or customer information.

14. Solutions Must Span Two Worlds The fundamental issue in addressing these issues is that solutions must understand two different worlds. Click: Addressing applications issues requires an understanding of what the application and the user are actually trying to do. This means that the solution must be able to �see� application layer information, understand what the various application-layer vernacular, and then take action based upon this. In short, the solution needs to be user and application-aware. Click: But applications are also delivered across networks, and many of the means of addressing issues involve network elements. So the solution must have the ability to tightly integrate and interact with networking elements. In short, the solution must be network savvy.

15. Which is where Citrix NetScaler comes into play. NetScaler, and specifically the AppExpert Policy Framework span the gap between applications and their associated technologies, and the network and its associated technologies and vernacular. Click: NetScaler has full visibility into Web transaction requests and responses. Administrators can define policies � using the intuitive AppExpert Visual Policy Builder � for accelerating applications, providing application level security, etc. based upon what is going on within a specific transaction and for a given user. Click: NetScaler is also tightly integrated with the network. Administrators can define polices � again using AppExpert � based upon networking/system level information (e.g., server health, least connections, etc.) as well. NetScaler lives in both worlds, helping to bridge the gap between applications and the underlying network.Which is where Citrix NetScaler comes into play.

16. Accelerate End-User Performance So how do we do it? First we provide an impressive set of advanced application acceleration technologies, reducing response times for all users, regardless of their location. Advanced TCP Optimization technologies such as client keep-alive, fast ramp, windows scaling and selective acknowledgement improve the performance of the underlying network infrastructure so that applications are delivered to clients more quickly. TCP Multiplexing efficiently consolidates large numbers of incoming client requests to a much smaller number of persistent backend connections, offloading expensive TCP set-up and tear down operations from your servers. TCP Buffering intelligently buffers application server responses and delivers them to the client at the client�s speed, freeing the server to perform other tasks. AppCache delivers in-memory content caching for both static and dynamically-generated application data, reducing the time needed to run reports and serve frequently accessed content. AppCompress compresses data traveling over HTTP or any TCP-based protocol, reducing bandwidth requirements and speeding the delivery of content to end users. SSL Offload provides high performance, hardware-based acceleration, freeing up backend servers from computationally intensive encryption processing. So how do we do it?

17. Ensure Maximum Application Availability Acceleration is provided on top of an extremely high performance traffic management system that ensures maximum application availability, even under the worst conditions. At the heart of every NetScaler system is the most powerful Load Balancing system in the industry. For more sophisticated traffic policy management requirements, our Layer 7 Content Switching capabilities guarantee that the right application data is served from the right application server to the right application client every time. In NetScaler 8.0, content switching policies can be defined based upon any information within the TCP Header or payload. This of course includes HTTP. Rewrite functionality can be used to insert, delete or make changes to content in HTTP requests or responses. The Responder Module provides content filtering and advanced redirection of user requests. Based upon business need, incoming requests can be dropped or forwarded. Or, NetScaler can respond with a custom created page, or send redirects back to the browser instructing the browser to request an alternative URL. NOTE: the difference between content switching and redirection is that in content switching NetScaler forwards requests on. In redirection, NetScaler sends a response back to the browser instructing the browser to send an alternative request. And our innovative Surge Protection capabilities maintain full application availability even during unexpected surges in client requests.

18. Enhance Application Security Finally, we include robust application layer protections The NetScaler Application Firewall provides application layer protections against attacks such as cross site scripting, forceful browsing, cookie poisoning and SQL injection that are used to steal valuable corporate and customer information. NetScaler includes protections against L4 and L7 denial of server (DoS) attacks The Responder Module also enhances application security by enabling granular filtering of incoming requests Finally, we include robust application layer protections The NetScaler Application Firewall provides application layer protections against attacks such as cross site scripting, forceful browsing, cookie poisoning and SQL injection that are used to steal valuable corporate and customer information.

19. The Application-layer Threat Protecting Web applications from application-layer attacks is critical for any application that contains sensitive corporate or customer information. Traditional security products like network firewalls and IPS devices are very important for network security, but they do nothing to stop web application attacks like SQL Injection, Cookie Poisoning, Cross-Site Scripting and Hidden Field Manipulation. Web attacks target weaknesses in the custom code of your web applications. Unless your web developers are security experts and write perfect code all the time, it�s easy for hackers to break right through and get access to your critical application data. The latest FBI Computer Crime Survey, in fact, reported a stunning 90% increase in web attacks last year. To make matters worse, more than 80% of web vulnerabilities were ranked as �Easy to Exploit� in the most recent Internet Security Threat Report. Government agencies around the world have also begun instituting new rules and regulations pertaining to data protection and loss notification, further enhancing the need for strong web application security protection.

23. Lets go back to the original problem, users and the applications they want. Click: First, we understand what is going on with the network Click: We then provide, via policies, the ability to manage, secure and accelerate web applications. This ultimately enables the network to bring business value to the applications Click: This business value is most directly seen by improvements in the users overall user experience. The applications run faster, they are more available and they are more secure Click: More strategically, these same policies also increase overall flexibility. NetScaler gives the network visibility into what is going on within the applications themselves. NetScaler�s inherent ability to decouple requests from responses (our patented request switching functionality) and take action (e.g., content switching or content rewrite) adds an element of loose coupling. These two capabilities used in together adds flexibility to the network, enabling the network to react more rapidly to changing application demands. This cuts the time and cost associated with change management, which can result in solutions being brought to market faster.Lets go back to the original problem, users and the applications they want.
