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.
About a month ago, I wrote a post on cloud load balancing versus application delivery controllers. In that post, I explored the core differences between cloud-managed load balancing and self-managed commercial load balancing, using an application delivery controller virtual appliance running over cloud infrastructure. In part two of this series, I take a closer look at some of the themes laid out in my earlier post with an emphasis on the role application delivery controllers play in addressing the challenges associated with migrating legacy applications to a general purpose cloud infrastructure.
Over the past 2 years, Radware has offered virtualized ADC appliances with virtual ADC instances that can be used on hardware appliances or on general-purpose servers. During this time, we’ve noticed two schools of thought emerging on the all-important question of vADC density. The first, argues that vADC density is one of the key criteria to consider when evaluating a virtualized appliance. The second, however, claims that organizations will typically avoid utilizing density higher than 10-16 vADC on a single piece of hardware. In search of greater clarity, we went back after implementing hundreds of ADC consolidation and virtualization projects with thousands of vADCs to check and see if there were any identifiable trends in vADC density deployment.
By now, we should all know that a load balancer is an integral part of the new cloud application stack. But while cloud vendors have been charging extra merely for offering more virtual servers, there are several key differences between a shared, cloud load balancer instance – offered by virtually all cloud providers (i.e. Amazon ELB, Rackspace CLB) and a cloud hosted, enterprise-grade application delivery controller (ADC). It’s time to set the record straight.
Big news from Radware at VMworld.
Today, Radware announced that its Alteon VA™ virtual appliance (one of many Radware application delivery solutions) has been integrated with VMware’s vFabric™ Application Director, a hybrid cloud provisioning solution. The joint solution is designed to simplify the creation of application deployment topologies across hybrid cloud services through the use of application deployment blueprints. Radware customers will be able to deploy their Radware Alteon VA in any VMware vCloud-powered private, public and hybrid clouds.
But wait, there’s more . . .
In the two former parts of my blog series, I shed light on the key trends impacting the next-generation data center, including consolidation and virtualization. In this post, I’d like to complete the full picture and talk about the rest of the trends – connectivity, convergence and green IT. So here we go:
Here is a trivia question to all of you website owners or web application administrators: could your online business do better if your website would perform better… always?
Not many are aware what a one second faster response time of a web application can do for their online business. According to KissMetrics, a web measurement company, a one second faster page load time can result in a 7% conversion rate and corresponding revenues. Also, a major research firm reported that a one second faster load time can increase page views by 11% and decrease abandonment rates by 16%.
If you’re part of the IT/network infrastructure industry or, even better, if you own an application or a line of business (LOB), you surely know that the data center has some well known requirements including application availability, performance and security. These can be addressed using an Application Delivery Controllers (ADC) or, simply put, a load balancer. While Radware is not the only ADC vendor out there, it does provide one of the finest ADCs and definitely the most future-proof ADC on the market: The Alteon 5224.
With Thanksgiving right around the corner, businesses everywhere are readying themselves for the post-holiday shopping blitz. And with the National Retail Federation predicting that sales will increase by 2.8 percent this holiday season, Cyber Monday promises to be lucrative for retailers that are prepared.
In anticipation of Cyber Monday, online retailers need to assure that tools are in place to minimize downtime when web traffic spikes, and that applications are available as customers make purchases from their mobile devices.
