Istio features and specs

  • Traffic Management
    Istio provides powerful traffic management capabilities, including fine-grained control over the flow of traffic and API calls between services.
  • Observability
    Istio enhances observability with metrics, logs, and tracing, making it easier to monitor microservices and gain insights into performance and behavior.
  • Security
    Istio improves security by providing service-to-service and end-user authentication, as well as powerful policy enforcement for access control.
  • Policy Enforcement
    Istio allows for the enforcement of organizational policy and access control, making it easier to ensure compliance and governance.
  • Service Resilience
    Capabilities such as circuit breakers, retries, and timeouts make applications more resilient to failures and ensure greater availability.
  • Platform Agnostic
    Istio is designed to be platform agnostic and can be deployed on any Kubernetes platform, making it highly flexible.

Possible disadvantages of Istio

  • Complexity
    Istio adds a significant amount of complexity to a system, which can make it harder to manage, especially for teams without experience in service meshes.
  • Resource Consumption
    Istio can be resource-intensive, requiring additional CPU, memory, and storage, which can lead to higher operational costs.
  • Learning Curve
    There is a steep learning curve associated with Istio, making it challenging for new users to get up to speed quickly.
  • Operational Overhead
    Managing and operating Istio might require dedicated personnel and can introduce operational overhead, including the need for monitoring and updating the control plane and sidecar proxies.
  • Latency
    The addition of sidecar proxies and other Istio components can introduce some latency in the network traffic between services.

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.

  • Evaluating 2 Popular Service Meshes
    The decision to add a Service Mesh to an application comes down to how your application communicates between itself. If for instance your design is heavily asynchronous and relies on events and messages, then a service mesh isn't going to make a lot of sense. If however, you've built an application that is heavily reliant on APIs between itself, then a service mesh is a great piece of technology that can make this... - Source: dev.to / 7 months ago
  • Kubernetes Multi-Cloud Multi-Cluster Strategy Overview
    IstioIstio is one of the leading Kubernetes service mesh solutions. You can use Istio to set up multi-cluster networking, allowing workloads in one cluster to interact with those in other clusters. This gives you more flexibility in where and how you deploy your apps. - Source: dev.to / 7 months ago

    Bart: You raise a crucial point about the human aspect. While we address technical challenges, the time spent resolving errors detracts from other tasks. The community has developed products and projects to tackle these concerns and costs. One such example is Istio with Ambient Mesh. Another approach is sidecarless service meshes like Cilium Cluster Mesh. Can you explain what Ambient Mesh is and how it enhances... - Source: dev.to / 11 months ago

  • 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 / 6 months 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 / 6 months 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 / over 1 year 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 2 years ago
