AWS vs Azure vs GCP — an honest comparison

Choosing a cloud provider is a strategic decision that will shape your infrastructure for years. Each platform has genuine strengths, and the right choice depends on your existing ecosystem, technical requirements and geographic constraints. Here is a factual comparison of the three major platforms to help you make an informed choice — we present the data as-is, because an honest assessment serves you better than marketing claims.

AWS stands out for European SMBs through its unmatched service breadth, the Paris region for data residency, and a mature partner ecosystem. LCMH’s 7 certifications and 10+ years of hands-on experience ensure you get the most out of the platform.

Our 4-step methodology

Every engagement follows a structured process to ensure measurable results and knowledge transfer to your teams.

1. Discovery

We analyze your business context, technical constraints and objectives. This phase includes interviews with your teams, a mapping of your current environment and the definition of success criteria. Deliverable: scoping document with scope, timeline and budget estimate.

2. Audit

We assess your current infrastructure against the 6 pillars of the Well-Architected Framework. Every component is reviewed: security, performance, costs, resilience. Deliverable: audit report with prioritized recommendations and identified quick wins.

3. Implementation

We deploy the selected solutions in short sprints with intermediate deliverables validated by your teams. Infrastructure as Code, CI/CD, automated testing: every deployment is reproducible and documented. Your teams are involved at every step to ensure ownership.

4. Continuous optimization

After go-live, we set up the monitoring, alerts and dashboards needed for operations. We conduct quarterly reviews to identify optimization opportunities (costs, performance, security) and support you in adopting relevant new AWS services.

AWS services

Our expertise covers the entire AWS platform. Here are the services we deploy most frequently for our clients.

Compute

• Amazon EC2 — Virtual servers sized to your needs, with auto-scaling to handle traffic spikes. We select optimal instance families (compute, memory, GPU) and negotiate appropriate Savings Plans.
• AWS Lambda — Serverless functions billed per execution. Ideal for event-driven processing, API backends and automation. Zero servers to manage, automatic scaling from 0 to thousands of requests per second.

Storage and distribution

• Amazon S3 — Durable, cost-effective object storage for your files, backups, data lakes and static assets. Lifecycle policies to optimize costs across storage classes.
• Amazon CloudFront — Global CDN with 400+ points of presence. Accelerate delivery of your web content, APIs and media with edge caching, automatic HTTPS and built-in DDoS protection.

Databases

• Amazon RDS — Managed relational databases (PostgreSQL, MySQL, MariaDB). Automatic backups, read replicas, multi-AZ failover. You focus on your data, AWS manages the infrastructure.
• Amazon DynamoDB — Serverless NoSQL database with single-digit millisecond response times at any scale. Perfect for real-time applications, user sessions and product catalogs.

Containers and orchestration

• Amazon ECS / EKS — Run Docker containers at scale with ECS (AWS-native) or EKS (managed Kubernetes). We help you choose based on your team’s container maturity.

Infrastructure as Code

• AWS CloudFormation / CDK — Your entire infrastructure described in code, versioned and deployable in one click. We favor CDK (TypeScript/Python) for its productivity and testability, with CloudFormation as the deployment foundation.

Observability and security

• Amazon CloudWatch — Centralized monitoring of your metrics, logs and traces. Alerts configured on your business SLOs for proactive incident detection.
• AWS IAM — Fine-grained identity and access management. We apply the principle of least privilege with audited IAM policies and dedicated roles per service.

Well-Architected Framework

Every architecture we design follows the 6 pillars of the AWS Well-Architected Framework.

We conduct Well-Architected Reviews of your existing workloads with a detailed report and prioritized action plan.

Use cases

On-premise to AWS migration

Running physical servers or VMs in a datacenter is costly, rigid and increasingly risky as hardware ages. We manage your migration to AWS using a proven, phased approach that minimizes disruption to your business operations. The process starts with a thorough discovery phase: we inventory every server, database, application dependency and network flow using AWS Application Discovery Service and Migration Hub. This produces a complete migration map with interdependencies clearly identified.

Next, we define the right strategy for each workload — rehost (lift-and-shift for quick wins), replatform (move to managed services like RDS or ECS with minimal code changes), or refactor (redesign for cloud-native benefits). We execute migrations in planned waves, typically grouping 5–15 servers per batch, with automated cutover scripts and rollback procedures tested before each wave. AWS Database Migration Service handles live database replication with zero downtime for critical systems.

Post-migration, we validate performance baselines against pre-migration benchmarks, verify backup policies, and confirm security group configurations. We set up CloudWatch dashboards mirroring your previous monitoring so your ops team has immediate visibility without learning new tools on day one. We also run cost comparisons: our clients typically see 30 to 50% reduction in infrastructure costs within 3 months, driven by right-sizing, elimination of over-provisioned hardware, and the shift from CapEx to OpEx. Common quick wins include replacing always-on VMs with Lambda for batch jobs, moving file shares to S3 with Transfer Family, and consolidating multiple small databases into a single RDS Multi-AZ instance. The entire process is documented in runbooks your team can reference for future changes. For regulated industries, we ensure compliance artifacts (HDS, GDPR data residency in the Paris region) are maintained throughout the migration.

High-performance static website

Your brochure site or documentation deserves better than shared hosting. We deploy an S3 + CloudFront + Route 53 architecture with automatic HTTPS, sub-second load times worldwide, and hosting costs under €5/month for most sites. CloudFront’s 400+ edge locations ensure your visitors in Europe, North America or Asia get the same fast experience. We configure custom error pages, HTTP/3 support, and security headers (CSP, HSTS) out of the box. For SEO, we set up proper redirects, canonical URLs, and structured data. Continuous deployment via GitHub Actions or CodePipeline means every git push goes live in under 60 seconds with zero-downtime cache invalidation.

Serverless API

Building a mobile app or SaaS? We design REST/GraphQL APIs on API Gateway + Lambda + DynamoDB — a 100% serverless stack with no servers to maintain, automatic scaling, and per-request billing. This architecture handles everything from 10 requests per day to 10,000 per second without configuration changes. Ideal for startups and MVPs that need to iterate fast without infrastructure overhead. We add Cognito for authentication, WAF for API protection, and X-Ray for distributed tracing out of the box.

FinOps and cost optimization

Your AWS bill keeps growing and you don’t understand why — you’re not alone. According to Flexera’s 2024 State of the Cloud report, organizations waste an average of 28% of their cloud spend. We start with a deep audit using AWS Cost Explorer, Cost and Usage Reports (CUR), and Trusted Advisor to build a complete picture of where every euro goes. We identify the most common culprits: oversized EC2 instances running at 5–15% CPU utilization, unattached EBS volumes accumulating charges, idle RDS instances in development accounts, and NAT Gateway data transfer costs that balloon silently.

From there, we implement a structured FinOps governance framework. This includes setting up AWS Budgets with threshold alerts at 50%, 80% and 100% of target spend, configuring monthly cost allocation reports broken down by team, project and environment, and establishing tagging policies so every resource is traceable to a cost center. We analyze your usage patterns to recommend the right mix of Savings Plans (Compute or EC2 Instance) and Reserved Instances, typically covering 60–70% of steady-state workloads for maximum discount.

For immediate wins, we automate the shutdown of non-production environments outside business hours using AWS Instance Scheduler — this alone saves 65% on dev/staging costs. We migrate infrequently accessed S3 data to Intelligent-Tiering or Glacier, right-size instances based on CloudWatch metrics over 14-day windows, and replace NAT Gateways with VPC endpoints where possible. Our clients typically see 20 to 40% savings within the first quarter, with a detailed monthly report tracking progress against baseline. We also train your team on cost-aware architecture decisions — choosing Graviton instances over x86 for 20% better price-performance, using S3 Express One Zone for frequently accessed data, selecting the right DynamoDB capacity mode — so the savings compound over time rather than eroding.
