The Cloud is Not a Railroad – An Argument Against the Vertical Separation of Cloud Providers

 

There's a move to regulate cloud providers by vertically separating the services they offer.

Like railroads of yore, who were not allowed to provide freight services on top of their base services, cloud providers would not be allowed to provide services on top of their base platform services.

Vertical separation would be new to the cloud industry. Is it a good idea? Would it actually solve any problems? My answers are no and no, but probably not for the reasons you think. Let's dive in.

Here are a few useful resources for exploring this argument:

  • Maintaining monopolies with the cloud by Cory Doctorow. https://pluralistic.net/2022/09/28/other-peoples-computers.
  • A group advocating for fair licensing. https://www.fairsoftwarelicensing.com/our-principles.
  • Cloud Infrastructure Services -- An analysis of potentially anti-competitive practices by Professor Frédéric Jenny. https://www.fairsoftwarestudy.com/.

Now Cory is about 100x times smarter than I am, but this analogy is wrong:

That's why the trustbusters were so big on "structural separation": the principle that a business can own a platform or use the platform, but not both.

So this remedy is also wrong:

Rather than trying to construct rules that kept the referee honest even when they played on one of the teams, they Continue reading

Announcing: A Completely New and Updated Version of Explain the Cloud Like I’m 10

I've been working hard on a completely updated version of Explain the Cloud Like I'm 10 and I'm happy to announce it's ready!

You can buy version 2.0 at: https://www.amazon.com/Explain-Cloud-Like-Im-10-ebook/dp/B0765C4SNR.

 

If you've already bought, Explain the Cloud Like I'm 10, then you should just be able to update to the new version for free.

What's new? This version has about 2x the material. I go in-depth on:

  • The major cloud providers and all the different platforms for deploying workloads.
  • How to decide between cloud providers.
  • How to switch to the cloud.
  • How to decide if you should switch to the cloud.
  • Cloud economics and how to save money in the cloud.
  • How you can learn more and take your cloud adventure to the next step.
  • And lots more. So much more. 

In version 1 of the book, I didn't cover cloud providers in any detail. Almost all the new content is platform related, so that's fixed. And I say platform rather than cloud provider on purpose.

The biggest change in the book is it is now oriented around the "cloud model" as the ultimate goal for software development, deployment, and use, not just the Continue reading

Architecture of Max reHIT Workout

 

Today I have the pleasure of announcing my new app—Max reHIT Workout—on Product Hunt. Max reHIT Workout is an exercise app that guides you through interval workouts.

I won’t pitch the app here. I'll just say I’m proud of how it turned out and if you want an optimal algorithm for exercising, you might like it.

I know I haven’t been writing much lately. That's because there’s been very little evolution in software system architecture. It’s pretty much same thing, different day. In many ways that’s good, but it’s not interesting to write about.

This article, while definitely self serving, targets the choice of using a native iOS environment versus a cloud environment for an app. It’s a choice every developer must make. How do you make that choice? What are the implications? What choice would I make next time?

Scaling indexing and search – Algolia New Search Architecture Part 2

What would a totally new search engine architecture look like? Who better than Julien Lemoine, Co-founder & CTO of Algolia, to describe what the future of search will look like. This is the second article in a series. Here's Part 1.

Search engines need to support fast scaling for both Read and Write operations. Rapid scaling is essential in most use cases. For example, adding a vendor in a marketplace generates a spike of indexing operations (Write), and a marketing campaign generates a spike of queries (Read). In most use cases, both Read and Write operations scale but not at the exact same moment. The architecture needs to handle efficiently all these situations as the scaling of Read and Write operations varies over time in most use cases.

Until now, search engines were scaling with Read and Write operations colocated on the same VMs. This scaling method brings drawbacks, such asWrite operations unnecessarily hurting the Read performance and using a significant amount of duplicated CPU at indexing. This article explains those drawbacks and introduces a new way to scale more quickly and efficiently by splitting Read and Write operations.
