Reasons Why Rust is the Future of the Cloud

Even though many people still haven’t heard about Rust, this programming language is quickly growing in popularity. In fact, Rust has climbed the top 10 ladders of the most popular language in 2022. Open source projects like Deno, Polkadot, and Mozilla have rapidly adopted Rust.

At the same time, companies like Dropbox, Cloudflare, Microsoft, AWS, and Google have also boarded the Rust train. Let’s see what this language is all about and why it’s emerging as one of the most important languages of the decade.

What is Rust?

Mozilla created rust. It’s a low-level open-source language with a focus on performance and safety. Some of its main competitors, C and C++, have issues with memory errors and concurrent programs. Rust is designed to overcome these issues and give an outstanding performance.

Rust has no runtime garbage collection leading to fewer latencies, which is great for network services. C and Java rose in popularity because they could eliminate memory safety bugs. However, their mechanisms have created additional problems, including runtime overhead causing inconsistent performance.

Rust is the best alternative to these platforms because of its static compile-time garbage collector as it prevents bugs common in Python, Java, and C++. It facilitates a product development process and has built-in integration, unit, and documentation testing.

Why rust is excellent for building cloud infrastructure software

Companies are competing in the cloud domain and looking to develop more robust, faster, and more available solutions. It’s compatible with some universal cloud-native products like JFrog to meet some of the most demanding cloud computing needs that enterprises have. There are several reasons why Rust is quickly becoming the number one option for many enterprises.

It offers C-like performance

Rust and C have a similar brief keyword syntax, allowing them similar performance. Developers can use convenient abstractions to write code similar to C. Rust doesn’t need a garbage collector or runtime, which offers excellent runtime performance.

Companies don’t have to build infrastructure components to reduce the critical overhead of the cloud environment. At the same time, Rust offers safety and security without affecting the overall speed and performance.

Safe environment

Rust has a great compiler that offers improved memory safety. One of the core principles of this language is efficient memory management. The compiler performs compilation checks for errors and discards the garbage collector for improved security and performance.

It has a strict type environment combined with an ownership model delivering concurrency safety and compile-time verification. All of this combined reduces the validation and testing costs of cloud implementations.

Efficient memory usage

Cloud computing is a cost-effective option for application hosting, but cloud computing memory is expensive, and that’s where Rust can help. Rust can store data on the stack or the heap. It can clean and compile team memory that’s no longer needed.

This mechanism allows companies to use memory efficiently in cloud computing. Rust can provide a low memory footprint and better memory access.

Best Rust features

Lifetime annotations

Rust compiler keeps track of reference validity using “lifetimes.” These references point to specific variables. Developers can inform “borrow checkers” about how long certain references will be “valid” using lifetime annotations.

Borrow checkers can use lifetimes in many situations, but sometimes they might require the help of developers. With these features, Rust makes memory management optimization easy. That’s why it’s one of the best programming languages for the cloud.

Ownership system

Rust manages memory using an ownership system, unlike languages that look for memory not used while the program runs. The compiler checks several rules every time the operation is running. Every value has an “owner” variable, and only one variable can exist.

When the variable is out of scope, the ownership is dropped, meaning that the allocated memory is cleaned when there’s no access to the variable. These ownership rules improve control over memory and its safety.

Borrow checker feature

Rust’s borrow checker stops data races while compiling. Data races occur when multiple threads use the same memory simultaneously. Rust prevents this kind of behavior by enforcing specific actions:

  • It prevents moving values while borrowed;
  • It prevents moving a single value twice;
  • It ensures that all variables must be initialized before they can be used in any way;
  • It prevents access when mutably borrowed;
  • It prevents mutating while immutably borrowed.

Bottom line

The obvious benefits of the Rust coding language for the cloud have made many companies pay attention. Some of the major systems in Dropbox were rewritten using Rust, and the company claims that they’re happy with the results and that Rust has given them clear advantages. Rust is the future of cloud development, but there’s a constant need for clean, cost-effective, and flexible applications that can be developed and managed effectively, and that’s where Rust excels.
