Large ASP.NET websites - 1

Anything that represents customer hand-holding represents a failure of site design - Jim Buckmaster, Craigslist

What does it take to run a large ASP.NET website that can have 30+ million hits a day (500 - 600 pages per second)? You would have to ask Markus Frind who single handedly runs PlentyOfFish, a hugely popular on-line dating website. 

The stats & lessons (via High Scalability) about his site can be insightful to ASP.NET developers.

Tech Stats:
  • PlentyOfFish (POF) runs on ASP.NET, IIS, Akamai CDN, Foundry ServerIron Load Balancer
  • PlentyOfFish gets 1.2 billion page views/month, and 500,000 average unique logins per day. 
  • 2 load balanced web servers with 2 Quad Core Intel Xeon X5355 @ 2.66Ghz), 8 Gigs of RAM (using about 800 MBs), 2 hard drives, runs Windows x64 Server 2003.
  • 3 DB servers. No data on their configuration.
  • Approaching 64,000 simultaneous connections and 2 million page views per hour.
  • Internet connection is a 1Gbps line of which 200Mbps is used.
  • 1 TB/day serving 171 million images through Akamai.
  • 6TB storage array to handle millions of full sized images being uploaded every month to the site.

Lessons:
  • Creating simple things is the result of years of practical experience.
  • There isn't a single site in the top 100 that doesn’t use a CDN. 
  • "The bigger you get as a free site the less money you make per visit and the more it costs to service a visit."
  • You can't always listen to user responses. Some users will always love new features and others will hate it. Only a fraction will complain. Instead, look at what features people are actually using by watching your site.

Maven Crash Course - Learn Power Query, Power Pivot & DAX in 15 Minutes

Image
In the Maven Crash Course " Learn Power Query, Power Pivot & DAX in 15 Minutes ", Chris Dutton walks through a hypothetical business case while showcasing the power of modern Excel tools like Power Query, Power Pivot and DAX. Power Query is used to extract, transform, and load data from external sources like SQL databases, PDF and CSV files. A relational model is created to join the tables without writing a single formula. Exploratory analysis is done using Power Pivot and Data Analysis Expressions (DAX). Data Analysis Expressions is the language that we can use to define new calculated columns and measures to enhance our Data Model instead of the traditional cell formulas that we'd typically use if our data was stored in worksheets. Pivot Charts and slicers are used to design a simple interactive report that the sales managers can use to analyze revenue trends and product performance.

Oracle Cloud Infrastructure 2024 Generative AI Professional Course & Certification Exam (1Z0-1127-24)

Image
I was happy to learn about the Oracle Cloud Infrastructure 2024 Generative AI Professional Course with video tutorials and the Certification Exam (1Z0-1127-24) from their newsletter. I found it extremely useful, timely, and relevant. The course, with about 6 hours of videos, provided me with a comprehensive view of what it takes to build a Generative AI application. Although some parts reference OCI services, much of the course remains vendor neutral. Rohit Rahi and his team at Oracle have done a great job of structuring the beginner-friendly yet comprehensive course so well, covering all the essentials across four modules. The curriculum strikes an excellent balance between depth and accessibility.  While Gen AI output is typically non-deterministic, I was surprised to learn that they can be made completely deterministic under certain conditions. Specifically, in the OCI Gen AI service, setting the temperature parameter to 0 produces consistent, deterministic output for a g...
