1. The Origin Story of A Pets vs Cattle

Back in 2011 or 2012, the challenge was explaining the revolutionary difference between AWS, cloud-native applications, and cloud computing to customers. Traditional explanations were time-consuming. The quest for a concise explanation led to Bill Baker’s presentation on Scaling SQL Server.

Baker’s presentation focused on “scale-up” versus “scale-out” architectures, using an analogy of pets and cattle. This struck a chord, becoming the elevator pitch needed to explain the shift to cloud computing. The analogy emphasized the disposability of cattle and the uniqueness of pets, highlighting a new way of viewing servers.

The core message was that in the old way, servers were treated as pets. If Bob the mail server went down, it was a crisis. In the new way, servers were numbered like cattle. If www001 went down, it was replaced without fuss. This resonated widely, leading to the Pets vs. Cattle meme, which has since become a vital tool for understanding the cloud transition.

2. Defining A Pets vs Cattle: Core Concepts

Understanding the core definitions of pets and cattle is crucial for grasping the analogy.

2.1. Pets: The Indispensable Servers

Pets are servers treated as unique, indispensable systems that must never go down. They are typically manually built, managed, and “hand-fed.”

Examples of pets include:

Mainframes
Solitary servers
HA load balancers/firewalls (active/active or active/passive)
Database systems designed as master/slave (active/passive)

Alt text: Illustration of a server labeled “Bob,” personifying the concept of a pet server with individual care and attention.

The key characteristic of pets is that they are seen as irreplaceable. If a pet server fails, it requires immediate, hands-on attention to restore it.

2.2. Cattle: The Disposable Servers

Cattle are arrays of servers built using automated tools, designed for failure. No single server is irreplaceable.

Examples of cattle include:

Web server arrays
Multi-master data stores such as Cassandra clusters
Multiple racks of gear put together in clusters
Anything load-balanced and multi-master

Alt text: Depiction of a herd of cattle representing scalable and replaceable servers in a cloud infrastructure, highlighting the concept of disposability.

With cattle, failures are expected and handled automatically. The system is designed to “route around failures” by restarting failed servers or replicating data.

3. The Key Difference: Redundancy and Failure

The crucial difference between pets and cattle lies in how redundancy and failure are handled. In the old world, redundancy meant having two of everything, the ubiquitous HA pair in the enterprise data center. However, this is not enough.

The new approach assumes that failures can and will happen. Every server, every component must be able to fail without impacting the system. This is achieved through automation, replication, and distributed architectures.

4. The Educational Value of A Pets vs Cattle

The Pets vs. Cattle analogy has proven invaluable in educating IT managers, CIOs, and others about the fundamental shift in computing. It provides a simple, memorable way to explain the old vs. new paradigms.

The analogy helps people understand:

The importance of automation
The need for fault tolerance
The benefits of distributed architectures
The cost savings of cloud computing

5. Misinterpretations and Misuses of A Pets vs Cattle

Like any popular analogy, Pets vs. Cattle has been subject to misinterpretations and misuses. One example is the Kubernetes team’s use of the analogy to explain “Pet Sets,” which support stateful applications in containers.

The issue is that the examples of stateful applications supported by Pet Sets, such as Cassandra, Kafka, and MongoDB, are actually cattle-architected data store systems. These systems are designed for failure and match the definition of cattle.

The problem with this interpretation is that it implies that true pet-architected systems, such as an active/passive Oracle storage system, are supported by Pet Sets. While Pet Sets help with orderly setup of master/slave systems, they primarily target scale-out data stores, not true pets.

This matters because confusing pets with systems that require “special handling” instead of systems that “cannot fail” muddies the waters and hinders understanding of the new vs. old way.

6. Getting the Most Value from A Pets vs Cattle

To get the most value from the Pets vs. Cattle analogy, it’s important to stick to the core message: focusing on the disposability of servers. This concept, pioneered by Google, is the most important aspect of the analogy.

Losing sight of this focus, focusing on other aspects, or ascribing something not intended (e.g., stateful applications as pets) distracts from the true meaning of the analogy.

By understanding and accurately representing the origins of the meme, we maintain its value for helping those new to the disruption understand the foundational shift underway in how computing is delivered.

7. Expanding the Analogy: Beyond Pets and Cattle

While the core Pets vs. Cattle analogy is powerful, some have attempted to expand it to include other categories, such as “ants” or “children.” These extensions can be useful in certain contexts, but they also risk diluting the original message.

It’s important to remember that the primary purpose of the analogy is to highlight the shift from treating servers as unique, irreplaceable entities to treating them as disposable, automated resources.

8. The Rancher’s Dilemma: Reconciling Pets and Cattle

In reality, most organizations have a mix of both pets and cattle in their IT environments. This creates a dilemma for IT managers: how to reconcile the need for both types of systems.

The key is to understand the characteristics of each type of system and to manage them accordingly. Pets require more manual attention, while cattle can be managed through automation.

It’s also important to identify opportunities to migrate pet systems to cattle architectures. This can improve resilience, reduce costs, and simplify management.
