Performance Optimizations in a Cloud-Centric World
Moving your web operations to the cloud means having less control over the way your website operates. That's not a bad thing-it's actually advantageous given today's larger audiences and wider variety of media-but in an era when reliability is key to user satisfaction, how can you manage performance when third-party services run your site? In this O'Reilly report, author Andy Still points out performance risks associated with connectivity, data centers, third-party SaaS tools, as well as content delivery networks (CDNs) and other cloud-based systems. You'll then learn several methods to help you identify and mitigate these risks. This report explains why you should: Embrace the cloud: the advantages of using these systems outweigh the disadvantages Understand the nature of cloud services you intend to use Closely monitor system elements that you don't control, with Real User Monitoring (RUM) and other tools Use a CDN and cache data as close to users as possible Retain an independent DNS provider, and use different cloud providers or CDNs for different segments of your audience Architect your systems to gracefully handle potential cloud service failures
