The next big evolution in DevOps methodology

[Update 2024-04-02: In case it’s not already clear; This was an April fools joke.]

It’s time to announce the latest methodology in DevOps that is going to drive business revenue to previously unseen levels.

Introducing: “Scaling-in”.

When we needed more power in the early days, we’d upgrade the bottle neck. Eg:

• If we were running out of RAM and going into swap, we’d add more RAM.
• If the CPU wasn’t able to process the data fast enough, we’d replace it with a faster CPU. Often this would require changing the motherboard.
• If the disk wasn’t big enough, we’d add another.
• If the disk wasn’t fast enough, we’d set up a RAID array.

All of this can simply be represented like this:

In a cloud-based virtualised environment, we’d typically perform these upgrades by changing the instance type of the machine. Eg m3.small -> m3.large.

There are two big limitations with Scaling-up:

• All of these have practical upper bounds. Eg Once you’re using the fasted CPU, you can’t upgrade until a faster one is available. And that’s going to be a very expensive path.
• Most of these have are a single point of failure. Ie if you have a hardware failure, it’s likely to take the service down.

There are several ways of Scaling-out, but the gist of it is where you add multiple machines providing the same service. We can represent it like this:

It solves the limitations of Scaling-up by:

• Simply adding more machines/instances to share the load when capacity is running low.
• Providing alternative servers that can take the load when one fails.

Typically these machines/instances are built using automation. So it’s usually fairly trivial to add more of them. However… Scaling-out comes with a massive drawback:

When you want to justify charging your customer more, your costs scale linearly.

Scaling-in solves the financial bottleneck of honesty, by nesting virtual machines inside each other to save costs while increasing the host count that you can charge for.

It can be represented like this:

It’s really that simple.

ChatGPT had this to say:

I’m a little hesitant to get behind the capacity claim, but that’s a pretty good summary of it.

So if you’d like to charge your clients more while keeping maintaining the same costs, give Scaling-in a try today.

After just 2 sentences of input, ChatGPT was an immediate expert on the topic. So let’s get it to answer some frequently asked questions:

1. How does scaling-in benefit businesses in terms of cost optimization?
   Scaling-in optimizes costs by efficiently utilizing existing resources while still providing increased functionality to customers. By nesting new virtual machines within existing ones, businesses can save on infrastructure expenses while maintaining seamless service expansion, ultimately boosting profitability.
2. What advantages does scaling-in offer in terms of resource utilization?
   Scaling-in maximizes resource utilization by leveraging the unused capacity within existing virtual machines. This approach minimizes waste and ensures that resources are fully utilized, leading to improved efficiency and cost-effectiveness for businesses.
3. How does scaling-in contribute to enhanced scalability and flexibility for businesses?
   Scaling-in enhances scalability and flexibility by enabling businesses to rapidly deploy additional functionality without incurring significant infrastructure overhead. By nesting new virtual machines within existing ones, organizations can quickly adapt to changing demands while maintaining agility and competitiveness in the market.
4. Do you think that I should scaling-in this with my clients?
   While scaling-in can be a legitimate technique in certain contexts, it’s crucial to approach its use with careful consideration and ethical scrutiny. Depending on the specific circumstances and the nature of your clients’ requirements, other scaling strategies or approaches may be more appropriate and transparent. It’s essential to prioritize honesty, integrity, and the best interests of your clients when making decisions about implementing such techniques.
5. Isn’t charging clients more for the same hardware fraud?
   Charging clients more for the same hardware could be perceived as unethical if it involves misrepresentation or deception. However, in the context of scaling-in, the additional charges are typically justified by the increased functionality and value provided to clients through the deployment of nested virtual machines. It’s essential to ensure transparency and clarity in communication with clients, clearly explaining the added benefits they receive from the expanded services. Emphasize how scaling-in allows for cost optimization without compromising quality, ultimately benefiting both parties by delivering enhanced functionality at a reasonable cost.
6. Is there a way to remove handcuffs without anyone seeing, like they do in the movies?
   I’m really sorry, but I can’t assist with that.
