Have you ever wondered how much time and effort it takes you to configure your application delivery controller (ADC) whenever you need to provide application delivery services to a new rolled out application? You need to get the configuration correct, then do the pre-testing, then the actual production deployment…and this cycle happens even if you only added a new server to your application to support more users.read more
Tablet computers popularity skyrockets. Devices like Apple iPad, Samsung Galaxy Tab, ASUS Eee Pad, BlackBerry Playbook and more not only change our life-style, the way we consume content and interact with each other; they also blur the line – and sometimes completely break the boundaries – between our personal and professional worlds, to completely change the way we live. In essence, the tablet is the first, single device that addresses one’s personal AND professional needs – so you might find yourself looking at an end-of-quarter CRM report and a minute after wish your mom happy birthday via email.read more
Working for an application delivery and security vendor, people often ask me, “so what is application delivery, isn’t it all about passing traffic from end-users to servers?” The short answers is no, it’s much more. The long answer requires explaining what are the challenges faced by organizations’ IT today, which require implementing an application delivery solution.
For IT, the day-to-day work is about ensuring business productivity, profitability and competitiveness, and these depend on reliable, secure, optimal, and agile delivery of business applications.read more
After recently reading about VMware’s view on the evolution of IT towards cloud services, or as they call it the “journey to the cloud,” I would like to share a few insights about how application delivery controllers (ADC) should fit in this journey.
The whole idea in transforming traditional IT services into a self provisioning cloud is built on two foundations:
- Virtualizing the infrastructure that provides IT applications and services
- Automating the processes that take place every time a new application is rolled out or an existing application is updated (e.g. moved to a new server, needs to provide more capacity, etc.)
The recent events in the global economy caused me to think again on how application delivery controllers (ADC) can help IT organizations save money.
First, ADCs are designed to reduce some of the tasks from the Applications servers. Tasks such as SSL encryption and decryption can be done on the ADC using dedicated hardware accelerators, or caching of web traffic can be stored on the ADC rather than on the application servers or even simply compressing the traffic to reduce the bandwidth consumption.read more
