Stuff The Internet Says On Scalability For June 26th, 2020

Hey, it's HighScalability time!


 

Line noise? Perl? Still uncertain? It's how you program a quantum computer. Silq.

How TripleLift Built an Adtech Data Pipeline Processing Billions of Events Per Day

 

This is a guest post by Eunice Do, Data Engineer at TripleLift, a technology company leading the next generation of programmatic advertising.

What is the name of your system and where can we find out more about it?

The system is the data pipeline at TripleLift. TripleLift is an adtech company, and like most companies in this industry, we deal with high volumes of data on a daily basis. Over the last 3 years, the TripleLift data pipeline scaled from processing millions of events per day to processing billions. This processing can be summed up as the continuous aggregation and delivery of reporting data to users in a cost efficient manner. In this article, we'll mostly be focusing on the current state of this multi-billion event pipeline.

To follow the 5 year journey leading up to the current state, check out this talk on the evolution of the TripleLift pipeline by our VP of Engineering.

Why did you decide to build this system?

A Short on How Zoom Works

 

Zoom scaled from 20 million to 300 million users virtually over night. What's incredible is from the outside they've shown little in the way of apparent growing pains, though on the inside it's a good bet a lot of craziness is going on.

Sure, Zoom has made some design decisions that made sense as a small spunky startup that don't make a lot of sense as a defacto standard, but that's to be expected. It's not a sign of bad architecture as many have suggested. It's just realistically how products evolve, especially when they must uplift over weeks, days, and even hours.

Sudden success invites scrutiny, so everyone wants to know how Zoom works. The problem is we don't know much, but we do have a few information sources:

The DynamoDB Book: An Interview With Alex DeBrie On His New Book

 

You know nothing about DynamoDB. At least that’s what I realized the first time I heard Rick Houlihan give his now infamous talk at AWS re:Invent 2018 on Amazon DynamoDB Deep Dive: Advanced Design Patterns for DynamoDB.

In that talk Rick revealed for the first time the inner arcana of single-table design. Minds were blown. Weaknesses were revealed. Futures were changed.

As a mere novice in the ways of DynamoDB I realized there were many levels of understanding needed before one could become a true AWS Data Hero. For that we need a guide.

Our guide on the Hero’s Journey that is mastering DynamoDB is a wise young wizard named Alex DeBrie. Alex wrote what you might consider to be the Gnostic Gospels of DynamoDB: The DynamoDB Book.

 

 

You will know something after reading this book

But it's more than just a book. You can’t buy it on Amazon. Instead, Alex uses Gumroad to offer packages at three different price points along with a team option. Each level provides additional content:

  • Basic package ($79). A 450 page book and six cheatsheets.
  • Plus package ($129). 60-page Analytics supplement guide. 60-page Operations supplement guide. Five deployable code implementations.
  • Premium Continue reading

Free Google Book: Building Secure and Reliable Systems

 

Google added another book into their excellent SRE series: Building Secure and Reliable Systems. It's free to download, so don't be shy. 

It's not short: 557 pages and 21 chapters! So what's it about? In short it's about "reliability through the lens of security."

In long, Ana Oprea, one of the authors, gave a good overview. anaoprea:

There are multiple questions about what this book is about, who it's for and what might be relevant for me. We recommend going through the Preface to get answers to these questions. Copy/pasting a few paragraphs: "In this book we talk generally about systems, which is a conceptual way of thinking about the groups of components that cooperate to perform some function.

We wanted to write a book that focuses on integrating security and reliability directly into the software and system lifecycle, both to highlight technologies and practices that protect systems and keep them reliable, and to illustrate how those practices interact with each other.

We’d like to explicitly acknowledge that some of the strategies this book recommends require infrastructure support that simply may not exist where you’re currently working.

Because security and reliability are everyone’s responsibility, we’re Continue reading

One Team at Uber is Moving from Microservices to Macroservices

 

There may be an undiscovered tribe deep in some jungle somewhere that hasn’t made up their mind on microservices, but I doubt it. People love microservices or love to hate microservices. There’s not much in between.

So it means something when even a team at a company like Uber announces a change away from microservices to something else. What? Macroservices. But we’ll get to that. Think what you want about Uber the company, but from a software perspective Uber has been a good citizen.

Gergely Orosz, an Engineering Manager on the Payments Experience Platform at Uber, in a tweet signaled a change in architectural direction:
