Conclusion

3. Mapping the Internet Probing every single IP in the world
Using traceroutes to collect the path information

4. Challenges Load Balancing Unresponsive Routers
Multiple interfaces belonging to the same routers (IP Aliases)

5. Containers

6. How containers appeared
It works on my machine, but it won’t work on other developer’s machine
It works on my machine, but it won’t work on production
Different environments, different services

7. Linux containers (LXC)
Containers offer a way to virtualize an operating system
Process isolation
Limitted visibility
Resource isolation (CPU, Memory, I/O, network etc.)
Build your own environment, use them everywhere
Feels like different machines

8. Containers vs Virtual Machines
Use kernel of the host machines
Starts with an image
Easy to use
Super fast to start
You can run a lot of them in one hardware
Run services in an eye-blink
No hardware configurations, no running installers, no incompatibilities
More secure

9. Containers vs VMs continued

10. More about containers Readily available repositories
Making your own images
Pushing images to local or online repositories

11. Docker

13. Companies using containers
Uber - Yandex - The Washington Post
PayPal - Microsoft - The New York Times
E-bay - Yelp - Google
Spotify - Badoo - BBC- News
Facebook - Amazon

14. Container Networking
Host
Bridge
None
Publishing ports

16. Tomcat image

17. MySQL image

18. “From a drop of water a logician could infer the possibility of an Atlantic or a Niagara without having seen or heard of one or the other.”
— Arthur Conan Doyle

19. Cluster of Containers
Docker Swarm
Kubernetes
Mesosphere

22. Advantages of using cluster of containers
High availability
Scalability
Feels like one OS

23. Midar MIDAR small-scale MIDAR medium-scale MIDAR full (large-scale)
Capable of testing a small (<200) set of IP addresses
Using a single probe method from a single monitor
MIDAR medium-scale
Capable of testing a medium-size (<40000) set of IP addresses
Probing from a single monitor host
MIDAR full (large-scale)
Capable of testing an Internet-scale (at least 2 million) set of IP addresses
Probing from multiple monitor hosts
