A new Quocirca research report underlines the importance of application delivery controllers (ADCs) and the skills needed to deploy and manage them. So, what exactly is an ADC and where can you get one?
ADCs are basically next generation load balancers and are proving to be fundamental building blocks for advanced application and network platforms. They enable the flexible scaling of resources as demand rises and/or falls and offload work from the servers themselves. They also provide a number of other services that are essential to the effective operation of on-demand applications, these include:
Doing all this ensures providers of online services have the agility to remain competitive compared with the laggards that still rely on manual processes to try and achieve the same things or are just unable to.
As part of the research, but not included in the report, Quocirca asked about the awareness the respondents had about the suppliers of ADCs (300 IT managers in the UK, Ireland and Nordic region).
The best known supplier was Cisco; however, Cisco recently announced it would discontinue further development of its Application Control Engine (ACE) after losing more than half of its market share in over the past four years.
Two of the main beneficiaries of this are expected to be F5 an ADC specialist, which had the third highest awareness, and Citrix, which came fourth (number two was Juniper, another network giant). Citrix should benefit the most as the Cisco has further announced that it will partner with Citrix to resell its NetScaler product. However, Cisco’s exit from the market will probably lead many to review their options so all vendors have an opportunity to benefit.
Behind the big four in came Riverbed and Brocade, with Barracuda, A10 and Array networks being the least well known as ADC suppliers.
HP was also on the list offered to respondents. Most selected the option “did not know it had one” (which it does not) confirming that the pre-screening to ensure the respondents knew a thing or two about ADCs in the first place had been effective.
