Fat apps combined with SSL Everywhere strategies suggest a need for more powerful processing in the application delivery tier
According to Netcraft, who tracks these kinds of things, SSL usage has doubled from 2008 and 2011. That's a good thing, as it indicates an upswing in adherence to security best practices that say "SSL Everywhere" just makes good sense.
The downside is overhead, which despite improvements in processing power and support for specific cryptographic processing in hardware still exists. How much overhead is more dependent on the size of data and the specific cryptographic algorithms chosen. SSL is one of those protocols that has different overhead and impacts on performance based on the size of the data. With data less than 32kb, overhead is primarily incurred during session negotiation. After 32kb, bulk encryption becomes the issue.
The problem is that a server is likely going to feel both, because it has to negotiate the session and the average response size for web applications today is well above the 32kb threshold, with most pages serving up 41kb in HTML alone – that's not counting scripts, images, and other objects.
It turns out that about 70% of the total processing time of an HTTPS transaction is spent in SSL processing. As a result, a more detailed understanding of the key overheads within SSL processing was required. By presenting a detailed description of the anatomy of SSL processing, we showed that the major overhead incurred during SSL processing lies in the session negotiation phase when small amount of data are transferred (as in banking transactions). On the other hand, when the data exchanged in the session crosses over 32K bytes, the bulk data encryption phase becomes important.
An often overlooked benefit of improvements in processing power is that just as it helps improve processing of SSL on servers, so too do such improvements help boost the processing of SSL on intermediate devices such as application delivery controllers. On such devices, where complete control over the network and operating system stacks is possible, even greater performance benefits are derived from advances in processing power. Those benefits are also seen in other processing on devices such as compression and intelligent traffic management.
But also a benefit of more processing power and improvements in core bus architectures is the ability to do more with less, which enables consolidation of application delivery services on to a shared infrastructure platform like BIG-IP. From traffic management to acceleration, from network to application firewall services, from DNS to secure remote access – hardware improvements from the processor to the NIC to the switching backplane offer increased performance as well as increased utilization across multiple functions which, in and of itself, improves performance by eliminating multiple hops in the application delivery chain. Each hop removed improves performance because the latency associated with managing flows and connections is eliminated.
Introducing BIG-IP 4200v
The BIG-IP 4200v hardware platform takes advantage of this and the result is better performance with a lower power footprint (80+ Gold Certified power supplies) that improves security across all managed applications. Consolidation further reduces power consumption by eliminating redundant services and establishes a strategic point of control through which multiple initiatives can be realized including unified secure remote access, an enhanced security posture, and increased server utilization by leveraging offload services at the application delivery tier.
A single, unified application delivery platform offers many benefits, not the least of which is visibility into all operational components: security, performance, and availability.
BIG-IP 4200v supports provisioning of BIG-IP Analytics (AVR) in conjunction with other BIG-IP service modules, enabling breadth and depth of traffic management analytics across all shared services.
This latest hardware platform provides mid-size enterprises and service providers with the performance and capacity required to implement more comprehensive application delivery services that address operational risk.

Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome,” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.

The Internet of Things is in the early stages of mainstream deployment but it promises to unlock value and rapidly transform how organizations manage, operationalize, and monetize their assets. IoT is a complex structure of hardware, sensors, applications, analytics and devices that need to be able to communicate geographically and across all functions. Once the data is collected from numerous endpoints, the challenge then becomes converting it into actionable insight.
