Boring. Many people use that word to characterize the server industry, although “unexciting and boring” would be a more accurate description. Then why is it gaining so much attention and importance? How is the Arm-based server revolutionizing cloud services?
In this article, we will look more closely at the architecture of an Arm-based server, the advantages and disadvantages of this cutting-edge technology, and its potential applications in the cloud server space.
What are Arm-based Servers?
ARM stands for Reduced Instruction Set Architecture, or RISC, and is the foundation for the processor family that includes the Arm processor. ARM Limited is the company that develops it. They design the core CPU components and grant licenses for Intellectual Property (IP) to partner firms, who then alter the chips to suit their requirements. ARM neither fully produces nor markets any chips.
This server leverages ARM processors or chips rather than traditional x86 class CPUs as a result, the server architecture may generate targeted outcomes with reduced energy consumption. Arm-based servers provide a great advantage over the old x86 obviously as the digital times have drastically changed, things are not the same in the IT or digital world.
Key Milestones in Arm-based Server Development (Historic Overview)
A few years ago, there weren’t many options for the architecture of your PC. You either had the x86 from Intel or the x64 architecture from AMD. Even though x86 architecture is more than two decades old, the vast majority of computers still utilize it.
In the past, if you wanted the best CPU performance available, you had to purchase a high-end x86 chip. Alternatively, if you could afford it, you could get a PowerPC system or something more exotic. It appeared as though the industry’s reliance on x86 processors was growing rather than decreasing. x86 is an older architectural approach, with the first x86 CPU design launching in 1978.

Since Apple became a member of the x86 club more than a decade ago, many observers have concluded that the mass market’s period of non-x86 CPUs has ended. A few years later, they were forced to withdraw their statements, and Apple was involved once more.
The upcoming Arm-based servers have the potential to revive the server market.
Comparing Arm-based servers & Traditional x86 Alternative
A classic example of a “complex instruction set computer” (CISC) design is the x86 architecture. On the other hand, ARM’s “R” stood for “reduced instruction set computer,” or RISC. That is where the main distinction between x86 and ARM CPUs is found. Here’s a list of differences for you to look at and get a clearer perspective.
ARM Architecture:
- An integrated method wherein the physical platform of the integrated circuit includes CPU cores.
- The same physical platform houses hardware tasks such as peripheral component connectivity and I/O bus controllers.
- An internal bus, sometimes referred to as a system on a chip (SoC), integrates many functionalities.
- The two main factors influencing the choice of ARM processors are adaptability and integration.
- The arm-based server is made to be lightweight and generate less heat.
- The designs are modified by manufacturers to fit their particular gadgets.
- Represents an alternative system design with unique connection and performance priorities.
x86 Architecture:
- Complex Instruction Set Computing (CISC) architecture.
- A modular design featuring a motherboard and replaceable parts.
- CPU plus additional parts that are tailored for particular tasks, such as graphics cards, GPUs, memory controllers, storage, and processor cores.
- Simple to expand or change out components.
- More uniform system designs that are open to exploits such as “write once, run anywhere”.
- There are at least 981 instructions in x86-64, while the precise number depends on your count.
