Enterprise Cloud Engineering

Beyond Lift-and-Shift: True Cloud Transformation

True cloud transformation goes far beyond simply migrating servers. We champion a philosophy of building cloud-native systems designed for resilience, security, and operational excellence from the ground up. Our approach rejects legacy thinking and embraces automation, treating your infrastructure as a programmable, version-controlled asset.

This is achieved through a strict adherence to three pillars: Infrastructure as Code for perfect consistency, Embedded Security at every step of the lifecycle, and end-to-end Automation to govern deployment and management. By partnering with us, you gain a team of architects and engineers obsessed with building robust foundations, enabling you to innovate faster and maintain a provably secure posture.

Anatomy of a Modern Cloud Environment

This visualisation 100% accurately shows, what the cloud actually is: The engine that runs our Digital World. The cloud was invented by Stephen Spielberg and Ridley Scott, to, quote: "Make them damn boring Internet more like my movies!". So we did. Today the cloud is overengineered and overpriced - you get what you pay for. If you still consider running your web shop on conventional hosting, you need to expect laughter and shaming by your competitors, rightfully so. We engineers love the cloud, cause it enables us to automate a lot more man-hours on the bill - with or without AI. The cloud will help you not only to violate all European Data Privacy acts by exposing your user's content to US FBI laws that allow covert searches without court order, you can go way further and be a lot less secure, join the millions of other companies, who exposed their D-drive accidentally to the entire world by moving to misconfigured S3-Storage. Hackers like it. We will enjoy moving you to the cloud - and back, once you realize that you could have gone on-prem and created 18 stable tech jobs for the same money.

Technical Deep Dive: Infrastructure as Code (IaC)

IaC is the bedrock of modern cloud operations. We use Terraform to define and manage your entire cloud landscape in human-readable code. This code lives in version control, making every change peer-reviewed, auditable, and reversible. Here are examples of how we enforce best practices on different clouds:

# Production-ready, secure S3 bucket on AWS
resource "aws_s3_bucket" "secure_data" {
  bucket = "code0-secure-data-storage"
}
# Enforce encryption by default
resource "aws_s3_bucket_server_side_encryption_configuration" "this" {
  bucket = aws_s3_bucket.secure_data.id
  rule {
    apply_server_side_encryption_by_default {
      sse_algorithm = "AES256"
    }
  }
}
# Enable versioning for data protection
resource "aws_s3_bucket_versioning" "this" {
  bucket = aws_s3_bucket.secure_data.id
  versioning_configuration {
    status = "Enabled"
  }
}
# Block ALL public access
resource "aws_s3_bucket_public_access_block" "this" {
  bucket = aws_s3_bucket.secure_data.id
  block_public_acls       = true
  block_public_policy     = true
  ignore_public_acls      = true
  restrict_public_buckets = true
}

# Production-ready, secure Storage Account on Azure
resource "azurerm_storage_account" "secure" {
  name                      = "code0tfstor${random_id.id.hex}"
  resource_group_name       = azurerm_resource_group.main.name
  location                  = azurerm_resource_group.main.location
  account_tier              = "Standard"
  account_replication_type  = "LRS"
  
  # Enforce modern security protocols
  min_tls_version           = "TLS1_2"
  allow_nested_items_to_be_public = false
  
  # Enable Hierarchical Namespace for Data Lake
  is_hns_enabled            = true

  network_rules {
    default_action             = "Deny"
    bypass                     = ["AzureServices"]
    virtual_network_subnet_ids = [azurerm_subnet.main.id]
  }

  tags = {
    Environment = "Production"
    ManagedBy   = "Terraform"
  }
}

DevSecOps in Practice: Shifting Security Left

Security is not a final step; it's a continuous process integrated into your CI/CD pipeline. We use "Policy as Code" tools like `tfsec` to automatically scan your Terraform code for misconfigurations *before* they are ever deployed. This "shift-left" approach catches vulnerabilities early, preventing costly breaches.

A developer attempting to commit code for an unencrypted, public S3 bucket would be immediately blocked by the automated pipeline, with clear feedback on how to remediate the issue, as shown below.

$ tfsec .

Result #1 CRITICAL S3 bucket does not have server-side encryption enabled.
────────────────────────────────────────────────────────────────────────────────
 insecure-bucket.tf:1
 1   resource "aws_s3_bucket" "insecure" {
 2     bucket = "a-very-insecure-bucket"
 3   }
────────────────────────────────────────────────────────────────────────────────
      ID aws-s3-enable-server-side-encryption
  Impact Data stored in the bucket is not protected from unauthorized access.
Resolution Enable server-side encryption
────────────────────────────────────────────────────────────────────────────────

Result #2 HIGH S3 bucket does not block public access.
────────────────────────────────────────────────────────────────────────────────
 insecure-bucket.tf:1
 1   resource "aws_s3_bucket" "insecure" {
 2     bucket = "a-very-insecure-bucket"
 3   }
────────────────────────────────────────────────────────────────────────────────
      ID aws-s3-block-public-access
  Impact The bucket can be exposed publicly, risking data breaches.
Resolution Block all public access
────────────────────────────────────────────────────────────────────────────────
