Chapter 3. Case Study 3.8 Akamai technologies: Attempting to keep supply ahead of Demand, pages 182-185. Answer questions 1, 2, and 3 on page 185. Clearly cite all the sources.

1. Why does Akamai need to geographically disperse its servers to deliver its cus-tomers web content?
2. If you wanted to deliver software content over the Internet, would you sign up for Akamais service? Why or why not?
3. Do you think Internet users should be charged based on the amount of band-width they consume, or on a tiered plan where users would pay in rough propor-tion to their usage?

In 2017, the amount of Internet traffic generated by YouTube alone is greater than the amount of traffic on the entire Internet in 2000. Because of video streaming and the explosion in mobile devices demanding high-bandwidth applications, Internet traffic has increased over 500% since 2010 and is predicted to nearly triple by 2021 (see Figure 3.18). Internet video is now a majority of Internet traffic and will reach 82% by 2021, according to Cisco. Mobile platform traffic is expected to grow sevenfold from its 2016 levels by 2021. Cisco estimates that annual global Internet traffic will be around 3.3 zettabytes in 2021: thats 3,300 exabytes, or, in other words, 33 with 19 zeroes behind it!
In todays broadband environment, the threshold of patience is very low. Increased video and audio customer expectations are bad news for anyone seeking to use the Web for delivery of high-quality multimedia content and high definition video. Akamai is one of the Webs major helpers, and an overwhelming majority of the Webs top companies use Akamais services to speed the delivery of content. Akamai serves more than 30 terabits of web traffic per second. Slow-loading web pages and content sometimes result from poor design, but more often than not, the problem stems from the underlying infrastructure of the Internet. The Inter-net is a collection of networks that has to pass information from one network to another. Sometimes the handoff is not smooth. Every 1,500-byte packet of information sent over the Internet must be verified by the receiving server and an acknowledgment sent to the sender. This slows down not only the distribution of content such as music, but also slows down interactive requests, such as purchases, that require the client computer to interact with an online shopping cart. Moreover, each packet may go through many different servers on its way to its final destination, multiplying by several orders of magnitude the number of acknowledgments required to move a packet from New York to San Francisco. The Internet today spends much of its time and capacity verifying packets, contributing to a problem called latency or delay. For this reason, a single e-mail with a 1-megabyte attached PDF file can create more than 50 megabytes of Internet traffic and data storage on servers, client hard drives, and network backup drives. Web page load times for desktops have also increased significantly as pages become laden with more content of various types. Load times increased by over 60% from 2013 to 2015 and have continued to rise since that time, further complicat-ing content distribution. Akamai Technologies was founded by Tom Leighton, an MIT professor of applied
mathematics, and Daniel Lewin, an MIT grad student, with the idea of expediting Internet traffic to overcome these limitations. Lewins masters thesis was the theoretical starting point for the company. It described storing copies of web content such as pictures or video clips at many different locations around the Internet so that one could always retrieve a nearby copy, making web pages load faster. Officially launched in August 1998, Akamais current products are based on the
Akamai Intelligent Platform, a cloud platform made up of over 233,000 servers in 130 countries within over 1,500 networks around the world, and all within a single network hop of 85% of all Internet users. Akamai software on these servers allows the platform to identify and block security threats and provide comprehensive knowledge of network conditions, as well as instant device-level detection and optimization. Akamais site per-formance products allow customers to move their online content closer to end users so a user in New York City, for instance, will be served L.L.Bean pages from the New York Metro area Akamai servers, while users of the L.L.Bean site in San Francisco will be served pages from Akamai servers in San Francisco. Akamai has a wide range of large corporate and government clients: 1 out of every 3 global Fortune 500 companies, the top 30 media and entertainment companies, 96 of the top 100 online U.S. retailers, all branches of the U.S. military, all the major U.S. sports leagues, and so on. In 2017, Akamai delivers between 15% and 30% of all web traffic, and over 3 trillion daily Internet interactions. Other competi-tors in the content delivery network (CDN) industry include Limelight Networks, Level 3 Communications, and Mirror Image Internet.
Accomplishing this daunting task requires that Akamai monitor the entire Internet,
locating potential sluggish areas and devising faster routes for information to travel. Frequently used portions of a clients website, or large video or audio files that would be difficult to send to users quickly, are stored on Akamais servers. When a user requests a song or a video file, his or her request is redirected to an Akamai server nearby and the content is served from this local server. Akamais servers are placed in Tier 1 backbone supplier networks, large ISPs, universities, and other networks. Akamais software deter-mines which server is optimal for the user and then transmits the content locally. Web sites that are Akamaized can be delivered anywhere from 4 to 10 times as fast as non-Akamaized content. Akamai has developed a number of other business services based on its Internet savvy, including targeted advertising based on user location and zip code, content security, business intelligence, disaster recovery, on-demand bandwidth and computing capacity during spikes in Internet traffic, storage, global traffic management, and streaming services.

popularity of streaming video have provided Akamai with new growth opportunities. As more businesses and business models are moving to the Web, Akamai has seen its client base continue to grow beyond the most powerful Internet retailers and online content providers. In 2014, Akamai made a push to encourage Hollywood studios to use the cloud for feature films, touting its ability to handle uploads and downloads of large video files, to quickly convert files from one format to another, and to apply DRM protec-tions. Establishing partnerships with movie studios represented big business for Akamai, with an increasing amount of media consumption taking place on mobile devices through the cloud. Akamai has also made agreements to become the primary content delivery platform for cloud service providers like Microsoft Azure and Google Cloud Platform. However, the growth of streaming video has also created new challenges for Akamai, including increased competition from Comcast and Amazon, which have built compet-ing content delivery services. Amazons CloudFront content delivery network is already bringing in $2.3 billion in revenues. Many of Akamais largest clients, including Apple, Facebook, Google, Microsoft, and Netflix, are also increasingly shifting their content delivery operations away from Akamais platforms and onto in-house content delivery networks, putting downward pressure on the companys revenues and stock price, which dropped in response to lower first quarter earnings in 2017. Amazon in particular contin-ues to make inroads against Akamaiwhile Akamai still serves more top 100 domains, Amazon CloudFront serves the majority of the top million domains, suggesting that Amazon is steadily building its client base with mid-sized companies. Other competitors in content delivery, such as Cloudflare, Fastly, and StackPath also represent threats to Akamais continued dominance. Akamai is also acutely aware of the increase in cybercrime as more traffic migrates to the Internet. Growth in Internet traffic is good news for Akamai, but the company must also now deal with politically motivated cyberattacks, organized crime online, and state-sponsored cyberwarfare, not just against its clients, but against CDNs like Akamai itself. Akamai has continued to improve its Kona Site Defender tool, which offers a variety of security measures for Akamai clients. The tool protects against Distributed Denial of  out new improvements to Konas web application firewall and analytics features. Akamai also upgraded Site Defenders Web Application Firewall feature and developed modifica-tions to the tool that make it easier for its users to use. With DDoS attacks against CDNs on the rise, Akamai has also taken precautions to ensure that it can withstand an attack against its infrastructure. With so many businesses now dependent on the uninterrupted flow of content over the Internet, Akamai is in a very strong position to sell security ser-vices and analytics to its customers. Akamai has partnered with security companies such as Trustwave and China Unicom to sell products jointly and has also set itself up for future growth by moving into areas of the world with less developed broadband infrastructure, such as the Middle East. In 2015, Akamai opened an office in Dubai, hoping to bolster its presence in an area where the adoption rate for broadband is skyrocketing. In 2017, Akamai acquired SOASTA, whose flagship product, CloudTest, allows companies to test and analyze the performance of their websites and website applications and is used by Apple, Target, and Walmart. The move will add a valuable new offering to Akamais Web Performance Solutions group of tools. In 2016, experiencing rapidly increasing demand from its clients for security tools, Akamai announced it would restructure its business into two distinct units, one focusing on content delivery and media, and the other on website security. The improvements in Akamais security businesses have offset much of the slowdown in its content delivery business, with 60% of the companys overall revenue coming from its cybersecurity divi-sion in the first quarter of 2017. While the future of its content delivery business is cloudier due to increased competition and the challenges of Internet growth, the company remains profitable.
