Choosing a cloud platform for enterprise business goes beyond a simple price comparison. It’s a strategic decision that defines future architecture, operational efficiency, cybersecurity levels, and even corporate culture. The three public cloud giants — Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP) — offer a wide range of services but have unique strengths and features that are critically important to consider when migrating or building new infrastructure.
Ecosystem and platform maturity
Each platform has its own history and focus, which influences its ecosystem and maturity in certain areas.
- AWS is the pioneer of the public cloud, giving it the broadest set of services, the largest global infrastructure, and the most mature partner ecosystem. This often makes it the default choice for startups and companies seeking maximum flexibility and innovation.
- Microsoft Azure, on the other hand, emerged from Microsoft’s need to move its enterprise products to the cloud. This makes it a natural choice for enterprise companies already deeply integrated into the Microsoft ecosystem (Windows Server, SQL Server, Active Directory, Microsoft 365). Azure offers the best hybrid cloud integration (e.g., via Azure Arc, Azure Stack HCI).
- Google Cloud Platform (GCP) entered the game later but is catching up quickly, focusing on data, machine learning, and container technologies. GCP inherited many of Google’s internal technologies, such as Kubernetes (GKE), making it attractive for companies building cloud-native applications and actively working with Big Data and AI.
| Characteristic | AWS | Azure | GCP |
|---|---|---|---|
| Market maturity | Leader, broadest service spectrum | Strong player, especially for hybrid solutions | Rapidly growing, focus on innovation |
| Hybrid cloud | Offerings exist, but not primary focus | Best integration (Azure Arc, Azure Stack HCI) | Offerings exist, but not primary focus |
| Microsoft ecosystem | Integrations exist | Deepest integration (AD, SQL, M365) | Limited integrations |
| Containers/Kubernetes | EKS (Elastic Kubernetes Service) | AKS (Azure Kubernetes Service) | GKE (Google Kubernetes Engine) – pioneer |
| Big Data/AI/ML | Wide range of services | Growing range of services | Strong suit, innovative solutions (BigQuery) |
Security and compliance
For enterprise companies, security and regulatory compliance are critical. All three providers invest heavily in these areas, offering robust tools and certifications.
- AWS offers a wide range of security services, including AWS WAF, Shield, GuardDuty, Macie, Inspector. It holds numerous compliance certifications (SOC 1/2/3, ISO 27001, HIPAA, GDPR, etc.).
- Azure integrates security at all levels, utilizing Microsoft Defender for Cloud, Azure Sentinel, Azure Firewall, Azure DDoS Protection. Thanks to its enterprise origins, Azure has a strong position in compliance, especially for government agencies and financial organizations, offering a wide range of certifications and adherence to regional standards. Entra ID (formerly Azure Active Directory) is a key component for identity and access management.
- GCP also offers powerful security tools, such as Cloud Armor, Security Command Center, Cloud DLP. Google has extensive experience in protecting its own global services, which is reflected in the high level of security of the GCP infrastructure.
It is important to note that the Shared Responsibility Model applies to all cloud providers, meaning that part of the security responsibility lies with the client.
Cost optimization (FinOps) and pricing
Costs are one of the key factors when choosing a cloud platform. While direct price comparison is complex due to the variety of services and pricing models, some trends can be identified.
- AWS is known for its “pay-as-you-go” pricing model and flexible options such as Reserved Instances (RI) and Savings Plans for significant savings. However, due to the vast number of services, cost management can be complex without proper FinOps practices.
- Azure often offers attractive discounts for existing Microsoft customers through Azure Hybrid Benefit (using existing Windows Server and SQL Server licenses) and Enterprise Agreements (EA), which can significantly reduce TCO for companies with a large Microsoft installed base.
- GCP often offers automatic sustained use discounts without requiring upfront commitments, which is a unique advantage. Their pricing model is one of the simplest and most transparent.
For all providers, implementing FinOps practices for monitoring, analyzing, and optimizing cloud costs is critical, including rightsizing, using spot instances, and proper reservation planning.
How SL Global Service solves this
The SL Global Service team understands that choosing a cloud platform for an enterprise client is not just a technical but also a strategic decision that requires deep analysis of business goals, existing infrastructure, and budget constraints. SGS engineers, as a vendor-agnostic cloud integrator, provide objective expertise based on many years of experience working with all three cloud giants.
We start with a comprehensive IT audit to assess current infrastructure, applications, and security requirements. Based on this audit, a customized cloud architecture is developed, which may include a Multi-cloud or Hybrid Cloud strategy to maximize the benefits of each platform. For example, for companies with an existing Microsoft license base, we might recommend Azure for IaaS and PaaS, using Azure Virtual Desktop or Windows 365 for VDI, as well as Microsoft 365 for corporate communications. For applications requiring high scalability and containerization, we might use AWS EKS or Google Cloud GKE, applying a DevOps approach with Terraform and Kubernetes for automated deployment and management.
Cybersecurity is the cornerstone of our solutions. We integrate advanced solutions such as Microsoft Defender, Microsoft Sentinel, CrowdStrike, or Cisco Firepower, providing comprehensive threat protection. To ensure business continuity, we implement Backup/DR solutions using Veeam, Azure Site Recovery, or Zerto, guaranteeing adherence to RPO/RTO requirements. After migration or implementation, the SGS team provides managed cloud 24/7, including monitoring (Prometheus, Grafana, Azure Monitor) and proactive infrastructure management. We pay special attention to FinOps, using tools to optimize costs and ensure transparency of cloud budgets.
Choosing the optimal cloud platform for an enterprise company requires a deep understanding of business needs, technical requirements, and strategic goals. Instead of choosing the “best” platform overall, it is worth focusing on the one that best suits your unique use cases, existing investments, and long-term development strategy. Thorough analysis, pilot projects, and expert support are key to successful cloud transformation.
