NetScaler Ten is changing the number one Internet Delivery System (CLICK) into the Most Advanced Cloud Network Platform” and as we dig down into the details of TriScale, I hope you will see why this is a major launch for us and what the opportunities are (CLICK)
The #1 Internet Delivery System is now the Most Advanced Cloud Network Platform

3. Scale 3 Today’s Cloud Evolution Requires a Scale Revolution
NetScaler has been known for a long time for powering the largest sites, but not all datacenters are the same. When people need to scale, they scale in different dimensions, so ..

Introducing Citrix TriScaleTM Technology
“End Appliance Sprawl”
“Buy only what you need”
Simplicity with
Many-In-One
Elasticity with
Pay-As-You-Grow
So let’s dive a little deeper and see what this is all about (CLICK)
Our Elasticity with Pay as you grow means our customers don’t have to buy more capacity than they need. (CLICK)
And when they do hit the hardware limits and need more, Our new TriScale clustering with NetScaler Ten delivers an expandability that means they add more capacity with no down time(CLICK)
And finally our SDX allows the simplifying and flattening of the network that everyone is looking for and ends the sprawl of appliances that litter the data center

COMSUMERIZATION OF IT

PRIVATE & PUBLIC CLOUD
As we look at the IT industry today, a number of important trends are changing the way Datacenters are being designed, deployed and used from the largest corporations to smaller enterprises. (CLICK)
Consumerization of IT
There’s no question that the Consumerization of IT is happening—but what does it mean for IT? Workers accustomed to user-friendly consumer products quickly grow frustrated with IT organizations perceived as unresponsive, inflexible, or—worst of all—behind the times. The fast, responsive and adaptive experiences they are used to in their personal life, they now expect from their business life which creates a demand for highly interactive and easy-to-use experiences in the business environment.
Private and Public Cloud (CLICK)
Cloud computing is changing the way data is accessed and processed. Massive changes are happening in the corporate data center to capitalize on the advantages that the cloud brings. IDC predict Cloud services will account for 46% of net-new growth in overall IT spending. With private and public cloud infrastructure, organizations have an opportunity to reduce TCO dramatically as data volume increases. As we see an evolution toward greater use of private and public clouds, we see an increasing need for solutions that support hybrid cloud scenarios
Data Explosion (CLICK)
The volume of data in the workplace is exploding. According to IDC, digital data will grow by 50x over the next decade. As more and more data is created digitally and more and more communications and information is passed in new media format, there will be ever greater demands being placed on the platforms that store, secure, process and manage these massive volumes of data.

10. Introducing TriScale Clustering

Add capacity as needed
Scale-out to 32x
Highly efficient - eliminating idle resources
Highly fault tolerant - alternative to HA pair
Eliminate “Forklift Upgrade” - no network downtime

100% Customers agree

With Pay-Grow we already have the best solution to avoid forklifts – now it gets better.
With Scale-out clustering, you can start with two appliances in an HA pair and immediately benefit from the increased capacity (CLICK) and performance that our clustering delivers while still being prepared for an appliance failing. In fact (CLICK) 100% of the customers we surveyed in Beta agreed saying they wanted to be able to run an HA par in a cluster.
(Click) Once the cluster is set up, Capacity can then be added as needed. The cluster of NetScaler’s appear and act as one powerful unit (click) with a Scale-Out capacity all the way to 32 units.
( (CLICK) Efficiency is significantly increased as passive standbys become fully operational eliminating idle resources.
(CLICK) The cluster can be designed to cope with the loss of one or more members so it is a powerful alternative to HA pairs
CLICK) You can eliminate the major disruption of forklift upgrades and easily achieve zero downtime as you simply add and go.

11. Single Policy View for the whole Cluster
Cluster Master - CLIP
The way it works is that a netscaler cluster of 2 to 32 appliances all appear as one logical unit under control of a Cluster Master. This cluster master has an IP address, the CLIP, for unified monitoring, configuring etc. Should the cluster maser fail, another unit in the cluster automatically takes over.

18. Customer Use Cases
Perform statistical analysis of real- time data to gain deeper insight into overall application environment:
How much bandwidth is being consumed by the Top N users to a specific application URL
What are the response times for the most popular web pages. Do I need to add server resources or further optimize my application for better performance?
How many users are accessing my top web pages at any point in time?
What are the most popular referring sites to my application. I want to understand how users get to my site/page

19. NetScaler Adaptive Policy Control
Application data can be automatically fed back into the NetScaler policy engine to optimize application delivery in real-time
Specific client or application traffic can be targeted to change or create policy including:
Rate limiting when certain peaks occur
Redirection – redirecting requests from the top clients to a different site or data center transparently
Enhanced acceleration (e.g. compression and/or caching data)
Failover to backup vserver based on depth of surge queue

20. Customer Use Optimize my application delivery policy dynamically:
Cache Top N most hit web pages (during specified interval) to offload back-end servers and improve application responsiveness
Compress web servers responses for the most requested content to improve user experience and optimize NetScaler resources
Increase service to the Top N clients by moving them to a faster backend server

There are a whole load of wizard enhancements
Web Session Timeout – Sets the amount of inactivity (browse, launch, options, etc…) before a session times out and users must return to login page
Default Client Address Mode – Sets the default launch mode for the ICA client. Alternate and translated modes for Direct and Gateway are used when ICA Proxy session is traversing a Nating Firewall or XA/XD servers are located in a different routing subnet

30. Westwood TCP: Enhanced Congestion Control
Rapid growth of mobile devices accessing public facing websites drive the need for Westwood TCP
Significant performance improvement for long distance, high bandwidth links
Modified standard TCP Congestion and Control Algorithm ensures faster recovery and effective congestion avoidance
Designed to handle noisy mobile links (sporadic losses due to overlapping radio channels)
It is well known that TCP has a limitation on performance when it is used for data transfer over long distance and high bandwidth network, called “Long Fat pipe” implementation.
The current Standard TCP implementation rely on packet loss as an indicator of network congestion. The problem in TCP is that it does not possess the capability to distinguish congestion loss from loss invoked by noisy links. As a consequence, Standard TCP reacts with a drastic reduction of the congestion window. In wireless connections overlapping radio channels, signal attenuation, additional noises have a huge impact on such losses.
TCP Westwood (TCPW) is a small modification of Standard TCP congestion control algorithm. When the sender perceives that congestion has appeared, the sender uses the estimated available bandwidth to set the congestion window and the slow start threshold sizes. TCP Westwood avoids huge reduction of these values and ensure both faster recovery and effective congestion avoidance. It does not require any support from lower and higher layers and does not need any explicit congestion feedback from the network.
Westwood TCP is disabled by default on the system.

31. Click to Rule AppFw
Appfw Relaxation rules can now be deployed from the logs
The logs must be in CEF log format
Convenient option to relax a rule blocking a legitimate request
Click to rule app firewall is another big feature, which is all about how you can deploy the policy rules from logs. With the CEF logging enhancement, we got this benefit wherein using the CEF log formats, we can actually create an app firewall rule. Most of the time, it will be created to relax a rule blocking a legitimate request.
You right click on the log method on the UI, say “edit and deploy” or directly say “deploy.” If you say “edit and deploy,” the dialogue box you get wherein you see the rule parameters. You have an associated comment as well, so you know where this rule was generated from.
