AI System for Infrastructure as Code Generation

Manual writing of Terraform or Ansible configurations means hundreds of lines of code, constant edits, and human errors. One forgotten output or an incorrect tag—and infrastructure collapses. We solved this problem: developed an AI system that generates ready IaC code from a text description of requirements. Over our work, we've deployed it on a dozen projects and reduced configuration creation time by 80%.

What Problems We Solve

How AI Generation Handles Outdated Syntax

LLMs often use deprecated Terraform resources. Solution: we explicitly pass the provider version (e.g., AWS provider 5.x) in the prompt, and after generation run terraform validate and tflint. If errors occur, we send them back to the model with context.

Security Anti-Patterns

Open security groups, missing encryption at rest. After generation, we run checkov—it finds problematic blocks. If detected, the model rewrites the configuration with vulnerability notes.

Hardcoded Credentials

LLMs sometimes insert placeholders like access_key = "AKIAXXXXXXX". We grep for patterns AKIA, secret, password before PR. Found strings are replaced with Vault variable references.

What Security Checks Do Generated Configurations Pass?

After generation, a full validation cycle runs: terraform validate, tflint, checkov, trivy for images in Kubernetes. If vulnerabilities are found, the model fixes them automatically. Additionally, we grep for hardcoded credentials. All configurations pass security checks before deployment.

How AI IaC Generation Works in Practice

Case: Generation of an ECS cluster with Fargate. The client needed to deploy a microservice with ALB, 2-4 Fargate replicas, RDS PostgreSQL, and VPC. Description took 10 minutes, the system generated a full Terraform module of 300 lines. After validation and one iteration—ready code that passed security scan with no issues. Manually, this would have taken 2 days. Budget savings exceeded 40% due to reduced man-hours. The system supports AWS, Azure, and GCP—each provider has its own validators and prompts.

Why AI Generation Is Faster Than Manual Writing

Comparison: a typical 200-line Terraform configuration.

Work Process

1. Analytics — gather requirements: cloud (AWS/Azure/GCP), services, scaling, budget.
2. Design — select generation template, set up prompts and validators.
3. Implementation — run generation, iteratively fix errors.
4. Testing — terraform plan, ansible-playbook --check, kubectl apply --dry-run=client.
5. Deployment — apply configuration, set up CI/CD for automatic updates.
6. Support — drift monitoring, provider updates, regeneration when requirements change.

What's Included in the Work

• Generation of Terraform, Ansible, Kubernetes manifests from your description
• Code validation: terraform validate, tflint, checkov, ansible-lint
• Drift detection and automatic PRs with fixes
• Documentation: module descriptions, variables, outputs
• Team training on working with the system
• 3 months of support after implementation

Typical Errors in AI Generation and How to Avoid Them

• Hardcoded credentials — always grep for AKIA, secret and replace with variables.
• Missing tags — every resource should have Environment, Project, ManagedBy tags. Add this to the prompt.
• Incorrect CIDR blocks — LLMs often generate overlapping subnets. Use cidrsubnet in the prompt or validate with terraform validate.
• Missing RDS replication — explicitly state multi_az = true in requirements.

Timeline and Pricing

Timeline: 3 to 10 days to set up generation for your project. Pricing is calculated individually—depends on infrastructure complexity and number of modules. We'll assess your project for free—just describe the task. We have over 5 years of experience and have implemented 15+ IaC automation projects. We guarantee that the generated code will pass all security checks.

MLOps: Infrastructure for Training, Deploying, and Monitoring ML Models

The model is trained, metrics — F1 0.94 on validation. Three months later in production, quality drops by 12%. No one knows when — there is no monitoring. It's impossible to retrain quickly — the training script is in a Jupyter notebook of a data scientist who has already left. Data for retraining is collected manually from three disparate systems. About half of the projects come to us with this pain. We build a turnkey MLOps platform: from experiment tracking to automatic deployment and data drift monitoring. We will assess your infrastructure in 1–2 weeks, and in 4–6 weeks you will get a basic MLOps core running in production. Our team has 10+ years of experience in ML infrastructure, over 50 implementations.

How does MLOps infrastructure benefit your ML projects?

Experiment Tracking and Reproducibility

Without tracking, an ML project turns into chaos: it's unclear which checkpoint is better, which hyperparameters were used, which dataset. Reproducing a result a month later is a quest.

Why is experiment tracking the foundation of reproducibility?

MLflow is an open source standard for tracking. It logs parameters, metrics, artifacts (models, graphs), and code. MLflow Model Registry is a centralized model storage with versioning and lifecycle stages (Staging → Production → Archived). Deployment via MLflow Serving or integration with external systems.

Typical initialization in code:

import mlflow

mlflow.set_experiment("fraud-detection-v2")
with mlflow.start_run():
    mlflow.log_params({"learning_rate": 3e-4, "batch_size": 64, "epochs": 10})
    mlflow.log_metric("val_f1", val_f1, step=epoch)
    mlflow.pytorch.log_model(model, "model")

This is the minimum. In production, we add logging of system metrics (GPU utilization, memory), dataset (hash, version), code (git commit hash). Weights & Biases — richer UI, collaboration features, sweep for hyperparameter optimization. MLflow — for on-premise deployment without external dependencies.

DVC (Data Version Control) — versioning of data and models on top of git. Data is stored in S3/GCS/Azure Blob, only metadata (hashes) in git. dvc repro reproduces the entire pipeline from raw data to metrics.

To ensure reproducibility of training, fix random seeds (torch.manual_seed, numpy.random.seed, random.seed) and record them in experiment metadata. Without this, debugging irregular results is painful. Log the dataset version (DVC hash) and git commit — then any experiment can be reproduced down to the byte.

Pipeline Orchestration: Kubeflow, Airflow, Prefect

A pipeline orchestrator becomes necessary when: A 100-line training script in cron is fine for simple tasks. But as soon as you have a multi-step pipeline (data loading → preprocessing → feature engineering → training → validation → deployment if quality above threshold), you need an orchestrator with retry logic, visualization, and alerts.

Kubeflow — Kubernetes-native orchestrator for ML (see Kubeflow). Each step is a Docker container. Supports parallel steps, conditional branches, artifacts between steps. Integrates with Katib (AutoML), KServe (serving), Feast (feature store).

Apache Airflow — more general DAG orchestrator. Wide ecosystem of operators (S3, Spark, DBT, Kubernetes). Easier to deploy if Airflow already exists in the company.

Prefect / Metaflow — less boilerplate. Prefect 2.x with @flow and @task decorators — quick start for small teams.

Typical training pipeline architecture on Kubeflow:

1. Data ingestion component — fetches data from S3/DB, validates schema via Great Expectations
2. Preprocessing component — transformations, normalization, train/val/test split
3. Training component — training on GPU, logging to MLflow
4. Evaluation component — metric calculation, comparison with baseline in Model Registry
5. Conditional deployment — deploy only if new model is better than current by >2% F1

Each component is a separate Docker image. Pipeline is versioned in git. Scheduled run (retraining once a week on new data) or manual.

Model Registry and Lifecycle Management

Model Registry is not just a checkpoint store. It is a centralized system that knows:

• Which model is currently in production (and with what metrics)
• History of all versions with training parameters
• Metadata: dataset, git commit, validation results
• Lifecycle stage: None → Staging → Production → Archived

MLflow Model Registry — standard. For enterprise — Vertex AI Model Registry (GCP), SageMaker Model Registry (AWS), Azure ML Model Registry.

Model promotion through stages: automatically move model to Staging after successful eval, then manual or automatic (during A/B test) promotion to Production. Rollback — switch to previous Production version in seconds.

Serving: From FastAPI to Triton Inference Server

Simple case. FastAPI + PyTorch/ONNX on one server — 80% of production ML deployments are exactly that. Sufficient for most tasks with load up to 100 req/s.

from fastapi import FastAPI
import onnxruntime as ort

app = FastAPI()
session = ort.InferenceSession("model.onnx", providers=["CUDAExecutionProvider"])

@app.post("/predict")
async def predict(request: PredictRequest):
    inputs = preprocess(request.text)
    outputs = session.run(None, {"input_ids": inputs})
    return {"label": postprocess(outputs)}

Triton Inference Server — production standard for high loads (500+ req/s). Dynamic batching, concurrent model execution, model ensemble. Supports TensorRT, ONNX, PyTorch TorchScript, TensorFlow SavedModel.

KServe — Kubernetes-native ML serving with autoscaling, canary deployments, A/B testing out of the box. Scale-to-zero for inactive models — savings on infrastructure up to 40% annually for a project with 10 models.

Monitoring: Data Drift, Model Drift, Infrastructure Metrics

Monitoring — what is usually done last and regretted first. Three levels.

Infrastructure monitoring. Latency (P50/P95/P99), throughput (req/s), error rate (4xx, 5xx), GPU/CPU utilization. Prometheus + Grafana — standard. Alert when P99 latency > threshold or error rate > 1%.

Data drift monitoring. Distribution of input data changes over time. Detect via PSI (Population Stability Index) for numerical features: PSI > 0.2 — strong drift. Chi-squared test for categorical, Kolmogorov-Smirnov test for continuous. Evidently AI — open source library with ready-made drift tests.

Model drift monitoring. If ground truth is delayed (e.g., we know conversion after a week) — monitor real metrics. If not — surrogate metrics: distribution of prediction scores, proportion of confident predictions.

Alerting. Three levels: INFO (minor drift, log it), WARNING (significant, notify team), CRITICAL (quality dropped below threshold — automatic switch to fallback model).

Why is data drift monitoring important?

Without it, you learn about model degradation only from user complaints or ringing SLA. A drift alert allows you to retrain the model in advance, before errors start causing losses. In one of our projects, PSI monitoring detected drift 2 days after a data source change — this saved the campaign.

Feature Store

Feature Store solves the training-serving skew problem. If preprocessing during training and inference is implemented in two different places — divergence is inevitable.

A Feature Store is needed when:

• Several models use the same features
• Features are computed from streaming data (real-time)
• Large team with different people on feature engineering and model training

Feast — open source Feature Store. Offline store (S3 + Parquet) for training, online store (Redis, DynamoDB) for low-latency inference. Feature definitions as code, materialization job syncs offline → online.

Tecton (commercial), Vertex AI Feature Store (GCP), SageMaker Feature Store (AWS) — managed options with less ops overhead.

CI/CD for ML

ML CI/CD is regular CI/CD plus specific ML steps.

ML-specific checks in CI:

• Reproducibility check: run training with a fixed seed, result must match
• Data validation: Great Expectations or Pandera on schema/distribution checks
• Model performance check: automatic eval on holdout, block merge if degradation > threshold
• Latency regression test: inference must meet SLA

GitOps for deployment. Merge to main → CI triggers training → eval → if passes → automatic deployment to Staging → smoke tests → manual promotion to Production or automatic upon successful canary.

Tools: GitHub Actions / GitLab CI for CI, ArgoCD for GitOps deployment on Kubernetes.
