Performance Optimizations in a Cloud-Centric World

Publisher: O'Reilly

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

Andy Still has worked in the web industry since 1998, leading development on some of the highest-traffic sites in the UK. He co-founded Intechnica, a vendor-independent IT performance consultancy, to focus on helping companies improve performance on their IT systems, particularly websites, and he is the creator of TrafficDefender, a cloud-based traffic-management tool.
