Foundation 2.0: The Ultimate Distributed BEAM Framework

Leveraging Best-in-Class Elixir Ecosystem Tools

Looking at your projects (ElixirScope, DSPEx) and the ecosystem reality, let’s reimagine Foundation 2.0 as the ultimate distributed BEAM framework that provides both “batteries included” simplicity and ultimate configurability by orchestrating the best existing tools.

Strategic Vision: Ecosystem Orchestration Over Reinvention

Instead of building everything from scratch, Foundation 2.0 becomes the intelligent orchestration layer that makes distributed BEAM applications trivial to build while leveraging proven tools:

  • libcluster for battle-tested clustering strategies
  • mdns_lite for zero-config local development
  • Phoenix.PubSub for distributed messaging
  • Horde for distributed process registries
  • Swarm for distributed process groups
  • Nebulex for distributed caching
  • partisan as an optional advanced overlay

Core Philosophy: Progressive Enhancement

Foundation 2.0 follows a progressive enhancement approach:

  1. Zero Config: Works locally with mdns_lite out of the box
  2. One Line Clustering: Add one line to get production clustering
  3. Advanced Configuration: Full control when needed
  4. Multi-Clustering: Support multiple clusters in one application

Developer Experience: From Zero to Hero

Level 1: Zero Configuration (Local Development)

# mix.exs - just add Foundation
{:foundation, "~> 2.0"}

# config.exs - NOTHING NEEDED
# Foundation automatically:
# - Uses mdns_lite for local service discovery
# - Enables distributed debugging via ElixirScope
# - Provides local clustering for development

Developer gets:

  • Automatic service discovery on local network
  • Multi-node development without configuration
  • Built-in observability and debugging
  • Hot code reload across development cluster

Level 2: One-Line Production (90% of use cases)

# config/prod.exs
config :foundation,
  cluster: :kubernetes  # or :consul, :dns, :static, :aws, :gcp

Foundation automatically:

  • Configures libcluster with optimal strategies
  • Sets up Phoenix.PubSub for distributed messaging
  • Enables Horde for distributed process registry
  • Provides health checks and metrics
  • Handles network partitions gracefully

Level 3: Advanced Configuration (Power Users)

config :foundation,
  clustering: %{
    primary: [
      strategy: {Cluster.Strategy.Kubernetes, [
        mode: :hostname,
        kubernetes_node_basename: "myapp",
        kubernetes_selector: "app=myapp"
      ]}
    ],
    secondary: [
      strategy: {Cluster.Strategy.Gossip, [
        multicast_addr: "230.1.1.251",
        multicast_ttl: 1
      ]}
    ]
  },
  messaging: %{
    adapter: Phoenix.PubSub.PG2,
    channels: [:events, :coordination, :telemetry],
    compression: true
  },
  processes: %{
    registry: Horde.Registry,
    supervisor: Horde.DynamicSupervisor,
    distribution_strategy: :hash_ring
  }

Level 4: Multi-Clustering (Enterprise)

config :foundation,
  clusters: %{
    # Main application cluster
    app: [
      strategy: {Cluster.Strategy.Kubernetes, [...]}
    ],
    # Dedicated AI processing cluster  
    ai: [
      strategy: {Cluster.Strategy.DNS, [...]},
      processes: [:ai_workers, :model_cache]
    ],
    # Analytics cluster
    analytics: [
      strategy: {Cluster.Strategy.Consul, [...]},
      processes: [:stream_processors, :aggregators]
    ]
  }

Integration with Your Projects

ElixirScope Integration

# ElixirScope automatically gets distributed debugging
defmodule MyApp.Application do
  def start(_type, _args) do
    children = [
      # Foundation enables distributed ElixirScope automatically
      {Foundation, cluster: :kubernetes},
      
      # ElixirScope now works across entire cluster
      {ElixirScope, distributed: true},
      
      # Your app
      MyApp.Worker
    ]
    
    Supervisor.start_link(children, strategy: :one_for_one)
  end
end

# Automatic distributed debugging
ElixirScope.debug_cluster()  # Debug across all nodes
ElixirScope.trace_distributed_request(request_id)  # Follow requests across cluster

DSPEx Integration

# DSPEx gets automatic distributed optimization
defmodule DSPEx.DistributedOptimizer do
  def optimize_across_cluster(program, dataset, metric) do
    # Foundation provides cluster-aware evaluation
    Foundation.Distributed.map_reduce(
      dataset,
      fn examples -> DSPEx.Evaluate.run(program, examples, metric) end,
      fn scores -> Enum.sum(scores) / length(scores) end,
      nodes: Foundation.Cluster.ai_nodes()
    )
  end
end

Smart Integration Layer

1. Intelligent Strategy Selection

Foundation 2.0 automatically selects optimal strategies based on environment:

defmodule Foundation.ClusteringStrategies do
  def auto_detect_optimal_strategy() do
    cond do
      kubernetes_available?() -> 
        {Cluster.Strategy.Kubernetes, kubernetes_config()}
      
      consul_available?() -> 
        {Cluster.Strategy.Consul, consul_config()}
      
      development_mode?() -> 
        {Foundation.Strategy.MdnsLite, mdns_config()}
      
      true -> 
        {Cluster.Strategy.Epmd, static_config()}
    end
  end
end

2. Unified Messaging Layer

defmodule Foundation.Messaging do
  @moduledoc """
  Unified messaging that works locally and distributed.
  
  Automatically routes messages via:
  - Direct calls for local processes
  - Phoenix.PubSub for cluster communication
  - Horde.Registry for process location

    case locate_service(service_name) do
      {:local, pid} -> 
        send(pid, message)
      
      {:remote, node, pid} -> 
        Phoenix.PubSub.broadcast(Foundation.PubSub, service_topic(service_name), message)
      
      {:distributed, pids} -> 
        # Send to all instances
        Enum.each(pids, &send(&1, message))
    end
  end
end

3. Process Ecosystem Integration

defmodule Foundation.ProcessEcosystem do
  @moduledoc """
  Intelligent process distribution using Horde + Swarm.
  """
  
  def start_distributed_ecosystem(name, spec) do
    # Automatically distribute across cluster
    case Foundation.Cluster.size() do
      1 -> 
        # Single node - use local supervision
        Supervisor.start_link(spec.children, spec.opts)
      
      size when size <= 10 -> 
        # Small cluster - use Horde for HA
        start_horde_ecosystem(name, spec)
      
      _large -> 
        # Large cluster - use Swarm for partitioning
        start_swarm_ecosystem(name, spec)
    end
  end
end

    MdnsLite.add_mdns_service(%{
      id: :foundation_cluster,
      protocol: "foundation",
      transport: "tcp", 
      port: get_epmd_port(),
      txt_payload: ["node=#{Node.self()}", "version=#{app_version()}"]

  defp build_strategies(:auto) do
    [
      foundation_auto: [
        strategy: Foundation.Strategy.Auto,
        config: [

        ]
      ]
    ]
  end
end

Partisan for Advanced Cases

defmodule Foundation.AdvancedClustering do

      true ->
        configure_partisan(config)
      false ->
        Logger.warning("Partisan not available, using standard clustering")
        :standard
    end
  end
  
  defp configure_partisan(config) do
    # Advanced Partisan configuration for large clusters
    overlay_config = case config.cluster_size do
      size when size > 1000 -> :client_server
      size when size > 100 -> :hyparview  
      _ -> :full_mesh
    end
    
    Foundation.PartisanOverlay.configure(overlay_config)
