Optimizing network performance is a task that spans multiple domains – from architecting the network, with capacity and topology (segmentation) considerations, through redundancy, bandwidth management and security aspects. But today, I would like to raise 5 additional ways to optimize overall network performance by best utilizing advanced Application Delivery Controller (ADC) capabilities for front end applications.
Now that HTTP/2 is here and widely adopted by client browsers, many of the performance challenges that existed with HTTP1.1 are finally addressed and solved. But what about security?
While HTTP/2 provides a higher level of privacy by mandating (de-facto because of browser implementation) traffic encryption, security solutions such as Web Application Firewalls (WAFs) are not keeping pace with the HTTP/2 evolution.
Since HTTP 1.1 was introduced 17 years ago, the Internet has evolved. This evolution introduced many changes, among them the development and delivery of rich content to users. These improvements enhanced the online experience, but did come at a cost – and the currency was performance. Performance challenges that HTTP 1.1 was never designed to handle.
As website owners and designers, we want to provide the best user experience to our clients. This often involves massive graphical design with an increasing amount of images on a site. According to HTTP archive, the number of images per page has doubled from 34 to 69 since 2012 until today and image payload has more than tripled itself. The implication of the data is fully visible – websites are indeed becoming more pleasant to the eye.
Application Delivery Controllers (ADCs) were once ubiquitous hardware-based appliances seen in data centers for the sole purpose of load balancing. However, this role has changed and the use of ADCs has expanded beyond their original purpose in an effort to keep up with the needs of the today’s IT pros.
The result is that ADCs now operate in a much less narrow function.
During the past year, I have had a few conversations with the CIO of one of our e-commerce customers in Europe. And like many online shops, his company was challenged by seasonal peaks of web traffic. I have often heard about these seasonal peaks, but I could never grasp how high they can go and their cost implications to an organization!
When managing the application delivery service of an off-the-shelf application like Microsoft Exchange, you can expect extensive support – from the application vendor, the Application Delivery Controller (ADC) vendor and all the professional forums across the Internet. QYBWBYG9DECS
While network performance challenges are often addressed by adding additional bandwidth, there are ways to yield more “good-put” (good net payload throughput) out of the same network infrastructure. In this blog post, I’ll discuss five improvements related to how a good application delivery solution can help.
It’s no secret application delivery controller (ADC) services are often perceived as complex to master and administer. Although they may use the latest ADC device, many ADC deployments only use basic layer 4 load balancing. It can be challenging to find an ADC champion who can really take advantage of the most advanced capabilities of an application delivery solution and maximize its business benefits.
The devastation wrought by superstorm Sandy is a stark reminder of just how fragile our environment is versus the power of nature. In just a couple of days, a single storm disrupted the lives of so many people and paralyzed a large number of businesses even days after it passed. In the wake of the storm, one of the questions on my mind is, how can we help businesses remain functional after such a massive hit regardless of their size?
Working for an Application Delivery Controller company, I’m no stranger to disaster recovery. Most often, disaster recovery is initiated by large enterprises that invest big money to build entire backup datacenters with the ability to automatically provide all online services in case their main datacenters become unavailable. A reality faced by many businesses in and around New York after the storm.
