Stuff The Internet Says On Scalability For October 19th, 2018

Hey, wake up! It's HighScalability time:

 

Now that's a cloud! The largest structure ever found in the early universe. The proto-supercluster Hyperion may contain thousands of galaxies or more. (Science)

Diving into the DNS

DNS OARC organizes two meetings a year. They are two-day meetings with a concentrated dose of DNS esoterica. Here’s what I took away from the recent 29th meeting of OARC, held in Amsterdam in mid-October 2018.

IXPs: Why Is the Middle East Lagging Behind?

On October 2nd, the Internet Society was happy to support the ITU in organizing the IXP Workshop on Peering and Interconnection in the Arab World “Towards unlocking regional interconnection opportunities” It was held in Manama-Bahrain, and kindly hosted by the Telecommunications Regulatory Authority (TRA) of Bahrain. This workshop was held on the eve of the Annual Meeting of the Arab ICT Regulators Network (AREGNET), and 30 regulators and 10 operators attended from all over the Arab region.

The workshop started with an overview of the Arab peering landscape given by Christine Arida, Director for Telecom Services and Planning at National Telecom Regulatory Authority of Egypt. Christine showed that the region is well served by undersea cables, with the oldest IXP established 20 years ago. However, all countries have either an underperforming IXP or do not have one at all. Regionally, cross-border interconnection is almost non-existent – with very few exceptions and most of the traffic is exchanged in London and Marseilles.

The debate started with an acknowledgement that strong and vibrant IXPs are needed in the Arab region. IXPs are a means and not the end… They are the enablers of digital transformation and a means to attract investment. Cheaper Continue reading

New: Expert ipSpace.net Subscription

Earlier this month I got this email from someone who had attended one of my online courses before and wanted to watch another one of them:

Is it possible for you to bundle a 1 year subscription at no extra cost if I purchase the Building Next-Generation Data Center course?

We were planning to do something along these lines for a long time, and his email was just what I needed to start a weekend-long hackathon.

End result: Expert ipSpace.net Subscription. It includes:

Orca: differential bug localization in large-scale services

Orca: differential bug localization in large-scale services Bhagwan et al., OSDI’18

Earlier this week we looked at REPT, the reverse debugging tool deployed live in the Windows Error Reporting service. Today it’s the turn of Orca, a bug localisation service that Microsoft have in production usage for six of their large online services. The focus of this paper is on the use of Orca with ‘Orion,’ where Orion is a codename given to a ‘large enterprise email and collaboration service that supports several millions of users, run across hundreds of thousands of machines, and serves millions of requests per second.’ We could it ‘Office 365’ perhaps? Like REPT, Orca won a best paper award (meaning MR scooped 2 out of the three awards at OSDI this year!).

Orca is designed to support on-call engineers (OCEs) in quickly figuring out the change (commit) that introduced a bug to a service so that it can be backed out. (Fixes can come later!). That’s a much harder task than it sounds in highly dynamic and fast moving environments. In ‘Orion’ for example there are many developers concurrently committing code. Post review the changes are eligible for inclusion in a Continue reading

Uptime Institute issues a weather warning for data centers

Data center operators have to take a number of contingencies into account, but many are failing to pay attention to the increase in natural disasters, such as hurricanes, floods, and wildfires.That’s the word from The 451 Group’s Uptime Institute, which published a report on the impact of natural disasters on data centers. Uptime issued the report to remind data center operators of the growing impact of climate change on data center operations.“Climate change is making us rethink resiliency and operational uptime. Now more than ever, it is crucial to understand any potential vulnerabilities to make new and existing facilities better prepared for extreme weather events,” the report states.To read this article in full, please click here
