How to build an independent and open hosting provider
OCF works with international partners to promote open culture in Taiwan. This time we have invited Mart from Greenhost to give a series of talks. This series comprises 3 talks:
Part 1: Physical Infrastructure
Part 2: Internet Resources
Part 3: Software stack - Open Source, Close source, WTF is Enterprice
Greenhost is a hosting provider headquartered in Amsterdam. They are a “green” hosting provider, they use environment friendly equipments to operate. Other than offering commercial services, they also support internet freedom and FOSS actively. They provide “Rapid Response Service” for activists and journalists when digital security incidents occur. They also built the Totem online learning platform for digital security, OpenAppStack, an open source all-in-one solution for file storage, chat, calendar and website, and Eclips.is cloud server platform.
Mart is the founder of Greenhost. He is familiar will datacenter operations and cloud computing technologies.
This talk is in English, it will be consecutively interpreted into Mandarin Chinese.
Talk two: Internet resources
What are essential internet resources and what do they do. And why does it matter. There are serveral Internet Resources which are essintial in running (internet) networks. The most vital ones ar IP address (IPv4 and IPv6) and AS numbers.
How are those resources distributed and what is required to obtain those addresses. Especially with the depletion of IPv4 addresses it can be hard to obtain those resources, while it is essential to have them to run an independent network.
In this talk the organisations responsible for distributing internet resources are highlighted and their role in the internet landscape. These are organisations like ICANN/IANA, APNIC, RIPE etc.
Those are open organizations, and everybody can become member. What can you do as member.
Although the organisations are open, it is essential to keep those organization independent as well. Can this be done and how do governments interact with those organisations.
AS numbers are unique numbers playing an essential role in internet routing. AS numbers are used by the border gateway protocol (BGP). This is the core of the internet. It is explained how this works and explained how weak the protocol is. The protocol relies heavily on trust, creating a thread to the internet. How do ISP work with this trust issue and what possibilities are there to mitigate those.
One of the possibilities to mitigate the trust problem, is the use RPKI, a certification system for routing. Although it is a nice system, it creates new (mostly political) risks.
Next to AS and IP space, there are domain names. The Domain Name System (DNS) is crucial for a working internet for humans. Organizations like RIPE, APNIC etc, play a small role in the DNS system as well, but the overall policy is set out by ICANN and the local registries. It is different model than the structure IP and AS resources.
Like DNS there are serval threats. Explained is how DNSSEC can mitigate those, but how that causes again new threats to the internet.
