1. AppFlux: EdgeBox-based Services for Apps Delivery and Distribution Ada Gavrilovska Georgia Institute of Technology 08/10/2015

2. InternetWi-fi/5G Rapid growth in types of devices and apps Evidence of end-user app preference App usage is exploding: - e,g, 80+B downloads now, >>200B 2017 Relies on cloud-based infrastructure (e.g., App stores and backend servers/services) Current State of Device Ecosystem

3. Challenges of Cloud-Supported App Model Long-haul Bandwidth Lost opportunity App discovery and distribution Source: Akamai state of Internet report Q1’2015

4. Alternative: Edge Boxes or eBoxes Provision-able distributed infrastructure outside data center. Situated beyond the last mile of Internet near end user. Examples of edge Boxes Enterprise Cloudlets: 4-40 servers, ~100 TBs, placed at strategic locations. Enterprise or private stand alone (micro-)servers, e.g., at home, malls, Starbucks etc. Nano: Integrated in devices like Wi-Fi routers, Xboxes etc.

5. Its not just us saying that … “Local cloud are essential for backbone and core network scalability” Geng Wu, Chief Scientist, Intel (Wireless World Research Forum, Oct. 22, 2013) “Edge services enable a huge amount of rich data to be processed in real time that would be prohibitively complex and costly to deliver on a centralized cloud” Phil Buckellew, vice president, IBM Mobile Enterprise (MWC Feb 25, 2013) “Mobile computing can get a serious boost from distribution of cloudlets on the internet” Victor Bahl, Director Mobility & Networking Research, Microsoft.(June 27, 2014)

6. AppFlux: Taming app delivery

7. 70% less traffic -- 2x faster app delivery

8. How “big” should eBoxes be? Popularity based (p-LRU) & Cost based (c-LRU)app cache

9. Ephemeral Apps: No install, streaming apps

10. 10x faster app discovery – No Performance impact
