Cloud
Datacenters are becoming much more all encompassing. They are now providing more services and capacity, particularly in shared service multi-tenant environments. Even enterprises are turning to cloud computing, public and private. Video, Web 2.0 are further driving utilization levels. Yet, the service level agreements not only must keep pace, but improve as well.
Transforming Infrastructure into a shared service
Cloud-scale performance – unmatched entity scaling
Accelerating Web 2.0 and video in the cloud
Supporting easy migration and management of app infrastructure
Bringing enterprise SLAs to the cloud

3. Growing Web Application Complexity
User volume increasing
More dynamic content
Video, voice, Flash, XML
Interactive media, embedded applets
More application-specific policies
Acceleration, Compression, Caching, Security
Rise in web app security threats
Web apps connect directly to most sensitive data
300% increase in web application attacks in past year (FBI)
Requires wire-speed inspection for application-layer attacks
More secure transactions requiring encryption
A series of trends have made the deployment of web applications even more complicated. (CLICK) The amount of traffic using web apps is growing exponentially with new forms of content. (CLICK) Video, interactive applications, AJAX all complicate deployment, response times, security, and availability.
As a result, to ensure server connectivity, great user experiences and secure communications, (CLICK) IT groups are installing solutions that provide acceleration techniques such as compression, static and dynamic caching, protocol optimization, and back-end session multiplexing.
By definition a standard firewall protects Layers 2-4 but web applications must be accessible from users, and hackers!
(CLICK) Hence web application firewall usage is needed to protect these applications from malicious use.
(CLICK) SSL VPN are growing in use and ideally the same solution should provide this as well.
(CLICK) As traffic can reach gigabit rates and more, the organization must have a solution that offers these protection rates.
Requires massive app-layer transactions/sec (HTTP/SSL)

In the background 2
The new applications being deployed are more complex that ever. Not only are there more of these applications in simultaneous use, and more users, but with techniques like AJAX, more packets that are smaller in size are transmitted and result in more connections. XML and other content is more chatty.
Just in a simple web exchange, you can be transmitting all kinds of agents, protocols, etc. These frameworks were virtually unknown a few years ago. They all travel over HTTP but SOAP commands, Javascript, and many more complications arise to slow data transfer and tie up servers.
New Web 2.0 applications make it worse by driving more connections.
Instead of being synchronous and only requesting content upon user interaction, data is transferred asynchronously – either in Ajax models where is requests are sent from the client, or Comet (reverse Ajax), which uses a more push model.
In either case, more and more connections.
To further illustrate app complexity, all Rich Internet Applications (RIAs) share one characteristic: they introduce an intermediate layer of code, often called a client engine, between the user and the server. This client engine is usually downloaded at the beginning of the application, and may be supplemented by further code downloads as the application progresses. The client engine acts as an extension of the browser, and usually takes over responsibility for rendering the application's user interface and for server communication.

5. Trends in Next-Gen Data Centers
More Dynamic
Modularity: rapid adoption to new Complex Web apps (SOA, Web 2.0, rich media-10X in processing)
Extensibility: provide a wide variety of app delivery services for any application need
Flexibility: deliver all types of applications with common infrastructure
Virtualization
Decouple application services from physical infrastructure elements
Dynamically shift back-end resources with no application disruption or change
“On the fly” provisioning and allocation of servers
Enterprise operations utilize most features
Concurrent use of App F/W, compression, SSL VPN, XML Security, caching, content switching, GSLB
Shift to 10 Gigabit infrastructure build-outs
Less network segmentation
“Wire-speed” throughput
Green computing: cutting power/cooling demands; smaller form factors
Flexible “pay as you grow” appliance options
Excess capacity for future feature support
While the actual protocols used are more complicated, so is the newer data centers.
These applications can easily result in an order of magnitude increase in processing power. Data centers are being designed with this is mind with new infrastructures. Applications need to be transparently and easily deployed without impacting the underlying network.
Virtualization is a hot topic these days for good reason. It minimizes resource and power requirements and reduces the manual changes by IT groups. Any application delivery must be able to work within this framework.
With the growing traffic demands, multi-gigabit build-outs are becoming common. This can reduce costly network segmentation but wire-speed throughput must still be achievable.
Power/gigabit is an important metric and with energy costs as they are today, it is critical that power use be minimized.
But with the trends in applications previously mentioned, data centers must install solutions with multiple features in as few of “point products” as possible; all while maintaining the throughput levels.
As the data centers grow, infrastructure components must scale to prevent needless replacement.

6. Resulting “Carrier-Class” Demands
Throughput approaching 40 Gbps and beyond
TCP connectivity levels in the tens of millions
Layer 7 requests per second in the millions
Encrypted traffic and application security exceed 10 Gbps
SSL transaction per second exceeding 100K
Simultaneous use of all the above and more!
The result is the need for truly high-end application delivery solutions that can handle the traffic deluge. Not only at Layers 2-4 but at the application layer as well. Secure traffic at high rates and application protection is critical.

MPX 7500 and MPX 9500
MPX 10500/12500/15500
Previously, Citrix NetScaler offered models including the 5500, 7500 , 9500, 10500, 12500, 15000,15500 and These designs provide from 500 Mbps to 18 Gbps. When you look at secondary performance specs, you get solid capacity for many enterprise, mid-size Internet-centric and some cloud computing applications. The 5500 is aimed at the many XenApp deployments where load balancing and GSLB of its various services including XML brokers, web interface servers, etc. Other smaller enterprises can use its economical pricing combined with full NetScaler functionality. The 7500 and 9500 models address larger enterprise needs and some mid-size Internet-centric operations. The mid-high 10500,12500, 15500, and fill the need for larger enterprises and mid-size Internet-centric, social networking, e-commerce and other operations.
NetScaler provides the best bang for the buck in the application delivery solution market. MPX uses a unique multi-core design to provide the best performance to price in the industry. Unlike competitive alternatives NetScaler not only integrates the most functions into one system but there are no limits to the use of these functions. Some other vendors will state you can run 1-2 modules max on their equivalent lower range designs. Yet, at Citrix we know these enterprise environments are more likely to run everything at once-caching, compression, content switching, app firewall, SSL VPN, and more. You should not be forced into tradeoffs and NetScaler ensures you don’t. As new functions are demanded by the market, these NetScaler’s scale very well.
But the new MPX 17500, 19500, and provide the added horsepower to the new datacenters. They solve the problems current large datacenters are experiencing. Large Internet-centric operations including social networking and search, cloud computing providers with multi-tenant demands, very large enterprises with private cloud operations, service providers and telcos all demand the utmost in performance.

13. State-of-the-Art Architectural Design
One very key attribute of MPX is the multi-core design. It is IMPERATIVE that when a user runs multiple functional modules simultaneously that performance degradation is minimal. MPX provides this support. Caching, compression, security features are spread across the multiple cores to ensure extensive feature concurrency.
When data centers run complex applications they cannot just expect an app delivery solution to be a fast load balancer. It must not only do that but also Layer 7 content switching, application protection, compression, etc. MPX is the only integrated ADC that supports ALL modules and at very high rates simultaneously. What’s more, the MPX architecture has room to grow with excess capacity. Here are the specs on the ultra high-end MPX

Application delivery solutions must understand BOTH the Application layer AND the underlying network.
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.
However, new demands are requiring not just a sophisticated understanding of Layer 7 applications, or scalable high performance but must address emerging virtualization requirements. This is where MPX solutions can really come to the forefront.

Here is an oversimplified model of IT operations – you have some monitoring tasks. You find something, you decide what to do with it, and once you decide, you act. NetScaler provides health monitoring and checks of the app servers and databases. NetScaler provides a series of policies to make complex decisions and allows action through scripts for high availability, surge queue protection, compression, etc.
As with any repetitive tasks within monitor-decide-act, you would like to automate the process (CLICK). Increasing automation reflects increasing maturity of the IT infrastructure, and reduced costs.
When you connect the various automations together such that the system can autonomously perform the monitor-decide-act cycle, you have arrived. (CLICK) At the Dynamic Datacenter.
We have a dynamic datacenter (DDC) capability that highlighting how NS enables enterprises to be more dynamic.

Here are the basic Citrix building blocks to provide dynamic data center support: NetScaler, XenServer and Workflow Studio (WS).
(CLICK) NetScaler constantly monitors the pool of utilized servers, their status, and availability.
(CLICK) Here NS determines more processing is needed, and notifies WS.
(CLICK) WS in turn notifies XenServer to add capacity
(CLICK) XenServer determines which virtual disk to bring-up, then XS provisions new servers.
(CLICK) WS is notified of the successful provisioning and sends a “capacity available” notification (CLICK) to NetScaler. (CLICK) NetScaler then adds the capacity to the pool of known servers for load balancing and other functions.
The whole process can then be reversed if/when excess capacity is provisioned. (5x CLICKS).
Once initial conditions are configured, the process is fully automated with IT real-time management not required.

17. MPX: Promoting Green Computing
Low power and Data Center Space needs:
20-70% less than competitive offerings on power/throughput ratings
Up to 77 Gbps/KW
1-2U designs: over 70% less data space compared to chassis designs
Increased functional integration
Maximum feature concurrency at high loads
Integrate point products: Load balancers, Caching, SSL VPN, Application Firewalls, etc.
Server farms reduced in excess of 50-80%
Minimized network segmentation
Maintain 10GE links
Fewer switches required
Green computing as stated is one of the growing trends and demands of IT administrators. MPX supports this.
When compared to competitive offerings, MPX products a substantial reduction on a power/throughout basis.
Being able to run numerous modules at the same time and at high rates for each module obviates the need for multiple point products and their associated power demands.
NetScaler has consistency prove its ability to cut server needs. Many Citrix customers have cut server needs, and the power they draw, by up to 50%. In one case near 90% less server needs. And that is without taking in the virtualization capability!
With the high throughput and ability to maintain 10GE links with minimal network segmentation, less switches and other components are used, thereby cutting more power.

18. NetScaler MPX-Series Summary
