NetScaler now with Citrix:

While at the Citrix Partner Exchange last week, we ended up learning about the new NetScaler product (Citrix bought the company not so long ago).
Much more than just a Load Balancer or Accelerator, this is more like a Full Application Switch with loads of Functions, Citrix see this (probably, ;-) as embracing and extending their reach further in to remote access infrastructure? (If I keep this up I could get a job with their Marketing Dept.?

 

What is it capable of doing? And what are the business benefits for Customers?

Short list:

Traffic Security & Protection Features

SSL Acceleration

Distributed Denial of Service Attack (DDoS) Defence

Content Filtering

Surge Protection

Priority Queueing

SureConnect

Traffic Optimisation Features

Compression (http and non-http)

TCP Offload

Persistent Client Connections

TCP Buffering

Consolidated Web Logging

FastRamp

Application Switching Features

Load Balancing

Content Switching

Cache Redirection

Integrated Cache

Global Server Load Balancing

 

Some example of how this has added value? (This was the anecdotes we got at the event....)

 

Microsoft’s MSN used to be hosted from                         84 Server running at an average of 80% CPU

This has now been reduced to                                           8 Servers running at an average of 30% CPU

 

NetScaler is installed at Ticket-master to help manage the traffic coming in to their on-line sales web site.

When Madonna or England Tickets are sold on-line at a specific time there may be anywhere from 1/2 to 1 million connections waiting – hitting the F5 key – to get access and buy tickets, this is the system that handles that sort of surge and load .

 

Google now has 200 installed pairs of NetScaler devices!! Originally got called in just to look at the DDoS side of things,.....

 

Prices will typically start at somewhere around £7K per device for *JUST* for Load Balancing, all functions listed above are driven from the same (2U) hardware, it’s simply a case of paying for additional licensing and then enabling it, at an additional cost, naturally....

 

I have included here an independent review of a NetScaler 9800 in a link to an SC Magazine article (best buy) where they carried out a group test on SSL Accelerators.

 

Other notes….

 did try to engage with NetScaler to supply some hardware at another client and they were not interested in talking to us, but now that they are part of the Citrix World and we have an established relationship they are very keen to talk to us.

 

Some ideas…

I'd imagine that any company with either a large Public facing Internet/Intranet/HTTP Farm would find this useful?

Equally, any company that front's large web client based apps could find this quite a cost saver?
(Above:- what I mean is that this device can make immediate savings on Oracle Clients working via Web/HTTP, etc..)
Have a look around using Google and I'm sure you'll find other ways of using this?

 

Summary:

There's no getting away from the fact that it's an expensive bit of kit, but depending on what you're trying to do and achieve, this could really save a lot of sweat and worry.......   might be worth getting them in to test?
