runc features and specs

Standardization
runc is part of the Open Containers Initiative (OCI), promoting standardization across container runtimes. This ensures interoperability and broad community support.
Lightweight
As a lightweight and fast CLI tool, runc provides a minimal runtime for environments where resource efficiency is critical.
Security
runc adheres to principles of secure software development and incorporates Linux kernel features like namespaces and cgroups to enhance security.
Broad Adoption
As the reference implementation for OCI, runc is widely adopted and tested in production environments, ensuring reliability.
Flexibility
runc offers the flexibility to handle low-level container configurations, making it suitable for advanced users needing granular control.

Possible disadvantages of runc

Complexity for Beginners
The low-level nature of runc can be daunting for beginners who might prefer higher-level tools like Docker that abstract away complexities.
Minimalist Design
While its simplicity is an advantage, runc lacks some of the advanced features and orchestration capabilities found in other container platforms.
Manual Configurations
Users need to manually handle configurations, which can be error-prone and time-consuming compared to automated solutions.
Ecosystem Integration
runc does not provide direct integration with tools and platforms by default, requiring additional setup for comprehensive ecosystem support.
Limited Features
Compared to complete container platforms, runc offers fewer built-in features, requiring supplementary tools to achieve similar functionalities.

Crow framework features and specs

Lightweight
Crow is a very lightweight web framework designed for C++ which makes it suitable for high-performance applications where resource efficiency is important.
Header-only
Being a header-only library, Crow is easy to integrate into existing C++ projects without the need for complex build configurations or additional dependencies.
C++14 Support
Crow requires C++14, which allows developers to use some modern C++ features that can help with writing more efficient and cleaner code.
Ease of Use
The framework offers a simple and straightforward API that makes setting up HTTP routes and handling requests more convenient compared to other more complex alternatives.
Good for Prototyping
Crow's simplicity and ease of setup make it a good choice for quickly prototyping web applications in C++.

Possible disadvantages of Crow framework

Limited Features
Crow may not have as many built-in features as some more established frameworks, making it necessary to implement certain functionalities manually.
Community and Support
The community around Crow is not as large as other more popular frameworks, which might limit the availability of community support and third-party resources.
Lack of Official Documentation
Crow's documentation may not be as comprehensive or up-to-date as other frameworks, which could hinder learning and development for new users.
Platform-Specific Limitations
Being a C++ framework, Crow might face platform-specific issues, and ensuring cross-platform compatibility may require additional effort.
Single-Threaded by Default
Crow is single-threaded by default, which could be a limitation for handling a large number of concurrent connections, although multithreaded operation can be configured.

Comparing 3 Docker container runtimes - Runc, gVisor and Kata Containers
Previously I wrote about the multiple variants of Docker and also the dependencies behind the Docker daemon. One of the dependencies was the container runtime called runc. That is what creates the usual containers we are all familiar with. When you use Docker, this is the default runtime, which is understandable since it was started by Docker, Inc. - Source: dev.to / almost 2 years ago
You run containers, not dockers - Discussing Docker variants, components and versioning
Now we have dockerd which uses containerd, but containerd will not create containers directly. It needs a runtime and the default runtime is runc, but that can be changed. Containerd actually doesn't have to know the parameters of the runtime. There is a shim process between containerd and runc, so containerd knows the parameters of the shim, and the shim knows the parameters of runc or other runtimes. - Source: dev.to / almost 2 years ago
US Cybersecurity: The Urgent Need for Memory Safety in Software Products
It's interesting that, in light of things like this, you still see large software companies adding support for new components written in non-memory safe languages (e.g. C) As an example Red Hat OpenShift added support for crun(https://github.com/containers/crun), which is written in C as an alternative to runc, which is written in Go( - Source: Hacker News / almost 3 years ago
Why did the Krustlet project die?
Yeah, runtimeClass lets you specify which CRI plugin you want based on what you have available. Here's an example from the containerd documentation - you could have one node that can run containers under standard runc, gvisor, kata containers, or WASM. Without runtimeClass, you'd need either some form of custom solution or four differently configured nodes to run those different runtimes. That's how krustlet did... Source: over 3 years ago

I forked Crow, an abandoned C++ Web Framework. And I'm currently maintaining it.
Last year I was looking to port a Flask REST API I made to C++ because speed and why not. I went through a few C++ frameworks but eventually chose the abandoned since 2017 Crow. It was by far the easiest to set up and work with (being inspired by Flask in the first place), and it didn't hurt that it supported Websockets. Source: about 5 years ago
