Spot.io features and specs

  • Cost Savings
    Spot.io helps businesses to significantly reduce cloud costs by up to 90% through its automated infrastructure management and optimization, particularly with the use of spot instances.
  • Automation
    The platform offers robust automation capabilities for infrastructure scaling, deployments, and workload optimizations, reducing manual overhead for IT teams.
  • Multi-Cloud Support
    Spot.io supports multiple cloud environments, including AWS, Azure, and Google Cloud, allowing for flexibility and easier management across diverse cloud infrastructures.
  • Enhanced Uptime
    Through predictive algorithms and workload management features, Spot.io maintains higher application availability and reliability even when using spot instances.
  • Integration Capabilities
    It has strong integration capabilities with various CI/CD tools, monitoring systems, and cloud services, making it easier to embed into existing workflows.

Possible disadvantages of Spot.io

  • Complexity
    The initial setup and configuration can be complex and may require a steep learning curve for teams unfamiliar with spot instances and automated cloud management.
  • Dependency on Spot Instances
    A significant part of the cost savings revolves around the use of spot instances, which can be preempted by the cloud provider, introducing the risk of downtime or disruption for certain workloads.
  • Cost Variability
    While cost savings can be significant, the use of spot instances can lead to variable costs, making budgeting and cost forecasting more challenging.
  • Limited Control
    Automated infrastructure management can sometimes lead to less granular control over specific configurations and instance choices, which might not be suitable for all types of applications or workloads.
  • Support and Documentation
    Users have reported that the support and documentation can sometimes be lacking, which can present challenges during troubleshooting and advanced configurations.

Dhall Configuration Language features and specs

  • Deterministic
    Dhall is designed to be a deterministic configuration language, meaning that given the same input, it will always produce the same output. This ensures consistency and repeatability across environments.
  • Type-Safe
    Dhall includes a strong static type system, preventing many common errors associated with misconfigurations. Types are checked at compile time, ensuring configuration values meet specific criteria before deployment.
  • Total Programming Language
    Unlike many other configuration languages, Dhall is a total functional programming language, which means every program written in Dhall will terminate. This prevents infinite loops and other runtime issues.
  • Interoperability
    Dhall can generate JSON, YAML, and other data interchange formats, making it highly interoperable with existing systems that require these formats for configuration.
  • Modular
    Dhall allows for modular configuration files. You can define reusable components and import them across different configurations, promoting DRY (Don't Repeat Yourself) principles.

Possible disadvantages of Dhall Configuration Language

  • Learning Curve
    While Dhall is designed to be simple, the presence of a type system and functional programming concepts can present a learning curve to new users, especially those without a programming background.
  • Tooling Support
    Compared to more established languages, Dhall has less tooling support. Users might find fewer IDE extensions, plugins, or community libraries to assist in development.
  • Limited Ecosystem
    Being relatively new, Dhall has a smaller ecosystem that may lack the breadth of community contributions, such as templates and integration examples, found in more mature configuration languages.
  • Performance Overhead
    The type checking and interpretation of Dhall can introduce some performance overhead compared to more traditional configuration formats like JSON or YAML, which are simpler to parse.
  • Complexity for Simple Configurations
    For simple configurations, the added complexity of Dhall's type system and functional features may be unnecessary, leading to overhead without a clear benefit.

  • Nvidia to Acquire Run:AI
    +1 In my previous stint, I had worked with Spot (https://spot.io/) as one of our vendors. Absolutely great product, amazing customer support and ability to take feature requests, or otherwise address our pain points quickly and effectively. - Source: Hacker News / about 1 year ago
  • Is k8s Kops preferable than eks?
    FWIW, I am also a big spot.io fan for our workload. During the holidays I run 30-50% spot instances and run 100% spot most of the year. Source: over 2 years ago
  • Is there anything else we can use beside tags and Cost Explorer to keep track of costs?
    Also, you definitely should look into Reservations, and (sale pitch coming) Spot can help you manage those. Source: over 2 years ago
  • AWS spot instances for CI jobs
    All of this is on spot-instances. We used spot.io (I believe the product is called "Ocean") and they basically took care of all the backend logic to make spot-instances available for the ECS cluster. Source: about 3 years ago
  • If I just focus on K8S does the Cloud provider matter much (GKE, EKS etc)
    Does cloud provider matter? I would say/think so. Not just cloud provider, but further more, how you set it up, which begets cloud provider. Are you setting it up with only the aws cli? Or did you terraform it? Maybe you chose a particular terraform module or maybe you used eksctl. Maybe you used kops or kubeadm. All these things matter when you get to cluster autoscaling, tainting particular node types to... Source: almost 4 years ago

  • Any program can be a GitHub Actions shell
    I'll give a shot at some guiding principals: 1. Do not use yaml. All github action logic should be written in a language that compiles to yaml, for example dhall (https://dhall-lang.org/). Yaml is an awful language for programmers, and it's a worse language for non-programmers. It's good for no one. 2. To the greatest extent possible, do not use any actions which install things. For example, don't use... - Source: Hacker News / about 1 month ago
  • StrictYAML
    I'm a fan of anything that moves us away from stringly typed nonsense. See also Dhall (which can render to yaml). I like the idea but found the veneer broke a little too often and left me squinting at Haskell. https://dhall-lang.org/. - Source: Hacker News / 2 months ago
  • Some Programming Language Ideas
    I think you're asking for Starlark (https://starlark-lang.org), a language that strongly resembles Python but isn't Turing-complete, originally designed at Google for use in their build system. There's also Dhall (https://dhall-lang.org), which targets configuration use cases; I'm less familiar with it. One problem is that, while non-Turing-completeness can be helpful for maintainability, it's not really... - Source: Hacker News / 4 months ago
  • 8 months of OCaml after 8 years of Haskell in production
    > Lambda calculus is as pure as can be, and also has terms that don't normalize. That is not considered a side effect. Many typed lambda calculi do normalise. You can also have a look https://dhall-lang.org/ for some pragmatic that normalises. > A better example of impurity in Haskell for pragmatic's sake is the trace function, that can be used to print debugging information from pure functions. Well, but that's... - Source: Hacker News / 5 months ago
  • Thoughts on ThoughtWorks Radar 2024
    I was first turned onto Pkl during my Dhall Trough of Disillusionment phase (Dhall is cool, but man is it hard) by James Ward. It looked to be a language that had enough types to compile YAML/JSON configuration files wayyyy more safely. I’ve had enough YAML/JSON misconfigurations break production, that I started looking into ways to compile those problems away, and Dhall helped a lot, but the learning curve and... - Source: dev.to / 6 months ago
