<h2>Types of Content</h2>
<ul>
  <li>static content: html, pdf, images</li>
  <li>steaming media: live or on-demand media</li>
  <li>dynamic content: assembles dynamic content on edge servers. ESI(<a href="http://www.esi.org">Edge Side Includes</a>) is similar to server-side include languages, but adds fault-tolerance features (for when the origin server is unavailable) Using ESI lets a content provider break a dynamic page into fragments with independent cacheability properties. ESI reduced bandwidth requirements for dynamic content by 95 to 99 percent.</li>
</ul>
<h2>Companies/Services</h2>
<ul>
  <li>Akamai: 15 and 30 percent of all web traffic, many large companies are using Akamai.</li>
  <li>CloudFlare: handles ~10% of web traffic including 7% of the million most popular websites. Cheaper; can start with the free plan.</li>
  <li>AWS CloudFront: if you use AWS.</li>
</ul>
