Back in 2000 (or 2001, I forget exactly), I got to test a variety of bandwidth management appliances. Oh, they were the bomb back then - able to identify (and classify) applications by nothing more than an IP address and a TCP port. Once identified you could set quotas on bandwidth consumption and burst capabilities. It was quite the technology, back then.
But that was before applications all starting using HTTP as if it were TCP. Between the rapid ascent of the Internet as place to do business and the webification (remember when that was a thing?) of applications there are very few applications that don't rely on HTTP as their primary "transport" protocol.
What that means is that there are a whole lot of very different applications that use port 80 (or 443). You can't, by port, determine anything about that application except that, well, it's probably HTTP and definitely TCP. Is it video? It is text? Is it interactive? Dynamic? Static? An API?
Having just the IP and Port is like having a street and house number but not knowing who lives there or what's inside. You end up sending mail to "our friends at" or "current resident" because you have no clue as to who actually lives there. Your marketing and offers are general, they aren't tailored or specific, and you've no clue if you're even reaching the right demographic. Oh, your coupons are delivered, but if I don't shop at your store anyway, you just wasted several cents on me that you could have saved had you known better. And several cents times thousands (or tens of thousands) of coupon flyers is a lot of waste.
Sometimes you hit the right house and your message is well received and appreciated, it has a positive result. But it's hit and miss. More often than not, you wasted time, effort and money because you were blind.
That's how it is in the network, where reliance on TCP and port number wind up rarely hitting a home run in terms of positive impacts, and the rest of them time end up as wasted effort.
It means that services like acceleration, optimization and security must be application-aware. They must be fluent in a given application's behavior and requirements in order to apply the right policy at the right time.
Which means anything operating at TCP or below isn't able to effectively do that. It means that without application layer (L4-7) services, you're pretty much out of luck in terms of how much you can leverage the network to impact the performance, availability and security of applications.
It means L4-7 is now critical, because it's only at those layers of the network stack that visibility into an application can be achieved and only at those layers can you execute the kinds of policies and functions needed today to make data centers more efficient and secure.
It means that without application-aware (and application-fluent) services your policies and processes in the network are executing either blindly or too broadly to have a real impact on the performance, reliability or security of a a specific application. It might be application-aware, but it's not application-fluent - or driven.
The IoT industry is now at a crossroads, between the fast-paced innovation of technologies and the pending mass adoption by global enterprises. The complexity of combining rapidly evolving technologies and the need to establish practices for market acceleration pose a strong challenge to global enterprises as well as IoT vendors. In his session at @ThingsExpo, Clark Smith, senior product manager for Numerex, will discuss how Numerex, as an experienced, established IoT provider, has embraced a ...

DevOps theory promotes a culture of continuous improvement built on collaboration, empowerment, systems thinking, and feedback loops. But how do you collaborate effectively across the traditional silos? How can you make decisions without system-wide visibility? How can you see the whole system when it is spread across teams and locations? How do you close feedback loops across teams and activities delivering complex multi-tier, cloud, container, serverless, and/or API-based services?

In the 21st century, security on the Internet has become one of the most important issues. We hear more and more about cyber-attacks on the websites of large corporations, banks and even small businesses. When online we’re concerned not only for our own safety but also our privacy. We have to know that hackers usually start their preparation by investigating the private information of admins – the habits, interests, visited websites and so on. On the other hand, our own security is in danger bec...

The Internet of Things (IoT), in all its myriad manifestations, has great potential. Much of that potential comes from the evolving data management and analytic (DMA) technologies and processes that allow us to gain insight from all of the IoT data that can be generated and gathered. This potential may never be met as those data sets are tied to specific industry verticals and single markets, with no clear way to use IoT data and sensor analytics to fulfill the hype being given the IoT today.

Enterprises have been using both Big Data and virtualization for years. Until recently, however, most enterprises have not combined the two. Big Data's demands for higher levels of performance, the ability to control quality-of-service (QoS), and the ability to adhere to SLAs have kept it on bare metal, apart from the modern data center cloud. With recent technology innovations, we've seen the advantages of bare metal erode to such a degree that the enhanced flexibility and reduced costs that cl...

Regulatory requirements exist to promote the controlled sharing of information, while protecting the privacy and/or security of the information. Regulations for each type of information have their own set of rules, policies, and guidelines. Cloud Service Providers (CSP) are faced with increasing demand for services at decreasing prices. Demonstrating and maintaining compliance with regulations is a nontrivial task and doing so against numerous sets of regulatory requirements can be daunting task...
