迁移到云计算模型显然会对部署的基础架构产生影响。这种转变已经在服务器，存储和网络的区域中看到，因为这些技术已经发展到“软件定义的”模型。并且似乎应用程序传递控制器（ADC）在类似班次的悬崖上。
In fact, a new ZK Researchstudy about cloud computing adoption and the impact on ADCsfound that, when looking at the deployment model, hardware appliances are the most widely deployed — with 55% having fully deployed or are currently testing and only 15% currently researching hardware. (Note: I am an employee of ZK Research.)
Juxtapose this with containerized ADCs where only 34% have deployed or are testing but 24% are currently researching and it shows that software in containers will outpace hardware for growth. Not surprisingly, software on bare metal and in virtual machines showed similar although lower, “researching” numbers that support the thesis that the market is undergoing a shift from hardware to software.
The study, conducted in collaboration with Kemp Technologies, surveyed 203 respondents from the U.K. and U.S. The demographic split was done to understand regional differences. An equal number of mid and large size enterprises were looked at, with 44% being from over 5,000 employees and the other 56% from companies that have 300 to 5,000 people.
Incumbency helps but isn’t a fait accompli for future ADC purchases
The primary tenet of my research has always been that incumbents are threatened when markets transition, and this is something I wanted to investigate in the study. The survey asked whether buyers would consider an alternative as they evolve their applications from legacy (mode 1) to cloud-native (mode 2). The results offer a bit of good news and bad news for the incumbent providers. Only 8% said they would definitely select a new vendor, but 35% said they would not change. That means the other 57% will look at alternatives. This is sensible, as the requirements for cloud ADCs are different than ones that support traditional applications.
IT pros want better automation capabilities
This begs the question as to what features ADC buyers want for a cloud environment versus traditional ones. The survey asked specifically what features would be most appealing in future purchases, and the top response was automation, followed by central management, application analytics, on-demand scaling (which is a form of automation), and visibility.
自动化的愿望是买方心态演变的积极迹象。就在几年前，仅仅提到自动化就会将其派遣陷入恐慌。现实是，没有自动化，它无法有效运行，技术专业人员正在开始理解这一点。
The reason automation is needed is that manual changes are holding businesses back. The survey asked how the speed of ADC changes impacts the speed at which applications are rolled out, and a whopping 60% said it creates significant or minor delays. In an era of DevOps and continuous innovation, multiple minor delays create a drag on the business and can cause it to fall behind is more agile competitors.

一个DC upgrades and service provisioning benefit most from automation
The survey also drilled down on specific ADC tasks to see where automation would have the most impact. Respondents were asked how long certain tasks took, answering in minutes, days, weeks, or months. Shockingly, there wasn’t a single task where the majority said it could be done in minutes. The closest was adding DNS entries for new virtual IP addresses (VIPs) where 46% said they could do that in minutes.
升级，配置新的负载均衡器和配置新的vep是最长的。展望未来，这将是大问题。随着数据中心获雷竞技电脑网站得更多分解和分发，它将在更多地方部署更多的基于软件的ADC。花几天或几周或一个月来执行这些功能将导致组织落后。
该研究清楚地显示了ADC市场的空气中的变化。对于IT专业人士，我强烈建议，随着环境转移到云端，评估新供应商是谨慎的。通过一切手段，看看你的现任供应商拥有什么，但至少在其他两个提供基于软件的解决方案的其他方面。此外，应该尽可能重点自动化，因此ADC的主要评估标准应该是实现自动化的容易。
