Blogs » Amazon AWS, Microsoft Azure, or Google Cloud – What Cloud Platform Should I Consider for My Next SaaS App?

As most businesses are moving to the Cloud, Software as a Service (Saas) solutions are becoming the new norm now. SaaS applications need a highly flexible and scalable infrastructure to run, and since most SaaS companies are moving out from on-premise data centers and are looking into cloud migration, this shifts the cloud battle among the leading cloud service providers.

There are many cloud options, but in this article, we will cover the three most popular in the industry. Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP) lead as the three top providers of infrastructure as a service (IaaS) and platform as a service (PaaS). The 2024 Gartner Magic Quadrant for Strategic Cloud Platform Services continues to recognize AWS, Microsoft Azure, and Google Cloud as Leaders. Microsoft ranks highest for Ability to Execute and furthest for Completeness of Vision, while Google Cloud stands out for its strengths in AI/ML and data analytics.

If you’re wondering, ‘Should I use AWS, Azure, or Google Cloud for my SaaS startup?’, this guide will help you compare options and make an informed choice. So, let’s dig deeper into some pros and cons.

Core Cloud Features for Every SaaS Application

Here are a few core cloud features that every SaaS application needs, and will be a core consideration when considering the cloud provider. When evaluating cloud infrastructure for SaaS apps, it’s critical to prioritize scalability, security, and compliance.

• Scalability
• Easy/fast way to code, deploy and launch
• Security
• Cost
• Services and Features
• Extensibility (ability to extend on top of what is built initially)
• Support
• Compliance (HIPAA, FedRamp, etc)

Following SaaS deployment best practices on cloud platforms ensures your app can scale efficiently, stay secure, and meet compliance standards.

Cloud Provider Comparison for SaaS Applications

Selecting a cloud vendor or provider for your SaaS will depend mostly on the workloads and the needs of the users. Some enterprises will rely on multiple providers to support every area of their operations. Before selecting a cloud provider for startups or enterprise SaaS, it’s essential to understand how each platform supports different workloads.

Developers are always in need of more convenient ways to run their databases, perform migrations, and backup efficiently. There are differentiating factors one should consider when choosing from the top cloud providers to determine which one is right for the SaaS business.

Here’s a high-level comparison of AWS, Azure, and Google Cloud Platform (GCP) to help you quickly assess their strengths for SaaS applications:

So, Which Cloud Should You Choose for Your SaaS App?

• Go with AWS if you’re building a scalable, HIPAA-compliant platform with complex infrastructure needs and plan to scale globally.

AWS vs GCP vs Azure Performance: Database Scalability

Cloud databases have various advantages in terms of scalability, security, and value for money. Database scalability is vital for high-growth SaaS applications, particularly when deciding between a multi-cloud vs single cloud SaaS architecture.

These top giants have similarities in database features, but the cloud functions may still vary based on the needs of a company or enterprise. When it comes to cloud comparison, let’s look at the strengths and weaknesses of these three big leaders:

AWS Database

Amazon Web Services offers the widest offering in Database as a Service (DBaaS). The three most used are Amazon RDS, Amazon DynamoDB, and Amazon DocumentDB.

AWS Aurora offers performance improvements over standard MySQL and PostgreSQL, but Azure SQL Hyperscale and Google’s AlloyDB now rival or exceed it in some transactional and analytical workloads, depending on the use case.

• Database Engines for Specific Needs – The Amazon RDS has six database engines to choose from: Amazon Aurora, MySQL, Oracle Database, PostgreSQL, MariaDB, and SQL Server. The AWS Database Migration Service can be used to migrate or replicate existing databases to Amazon RDS.
• Built for high performance – The Amazon RDS is fast and can handle higher loads. There are two SSD-backed storage options. The first one is built for high-performance OLTP applications, and the other one is for less demanding apps.
• Secure – It allows the control of network access to the database and runs the database through Amazon Virtual Private Cloud (Amazon VPC). Many AWS RDS engine types offer encryption at rest and encryption in transit.

However, AWS DBaaS is not for beginners. It requires the expertise and skills of data scientists and database administrators, or developers who are already familiar with AWS services. There are so many technicalities involved, making it less attractive for beginners.

Google Cloud Database

Google Cloud has been adopted by businesses of different sizes, and it offers DBaaS options:

Cloud SQL is also a DBaaS that can be used for MySQL, PostgreSQL, and SQL Server-based applications. This can be integrated with other Google Cloud services such as Kubernetes and BigQuery.

This can be used for application development and deployment, and a scalable database for containerized workloads

AlloyDB has become a cornerstone of Google Cloud’s database strategy. This high-performance, PostgreSQL-compatible database now powers many SaaS applications with demanding transactional workloads, offering significant performance gains over standard PostgreSQL.

The Cloud Bigtable is a NoSQL database that can be integrated with BigQuery and Apache. This can be used for financial analysis and IoT applications.

Google Cloud is said to be more user-friendly, especially if you’re operating with Kubernetes.

The Winner?

Now, to answer the question of which cloud offers more and faster databases, AWS Cloud wins this area with its vast and flexible offerings. However, AWS is not for everyone since its infrastructure is complicated and will require someone with experience in AWS.

Scalable Cloud Solutions for SaaS: AWS vs Azure vs GCP

Scalability is an important factor in choosing a cloud vendor for SaaS applications. One should never ignore the future challenges and the need to upgrade or scale.

Scalability in cloud computing means the infrastructure’s ability to handle the growing or diminishing needs of the business. In the traditional server and hosting, there are inconveniences such as having to pay for maintenance, adding additional server space, and interruptions in business operations. All those contribute to unplanned downtime, which is costly for the business.

An instance is created every time an application is deployed. Creating an instance means assigning a server to that app. Scaling happens when you assign more instances, which is termed scaling out. Scaling higher or bigger instances is called scaling up.

Amazon Web Service Scalability

AWS Auto Scaling, as the name suggests, will auto-scale applications and will adjust the capacity for manageable performance. This will also help with securing the lowest possible cost.

This also allows scale applications that are using Amazon EC2 or Elastic Compute Cloud instances, Amazon ECS tasks, Amazon Aurora replicas, etc.

Microsoft Azure Scalability

Azure Autoscale helps scale applications to the performance they need to meet the users’ demands. In this aspect, the distinct feature of Azure over AWS and GCP is its virtual machines.

The Virtual Machine is compatible mostly with widely used apps such as SQL Server, Oracle, IBM, Windows Server, SAP, and more.

Google Cloud Scalability

Google’s involvement in the development of Kubernetes led the company to use most of the latter’s container features. Computer Engine has machine types that are customizable with per-second billing and is important for adjusting the performance to cater to high workloads.

The Winner?

The three providers all offer scalability features in the form of auto-scaling. This auto-scale feature prevents apps or site downtime in the event of a traffic spike. Auto Scaling allows the machine to handle the high load and they can be pre-defined or customized based on the time and day when traffic skyrockets.

Which is Secure?

According to the 2024 IBM X-Force Threat Intelligence Index, more organizations are placing their trust in public cloud providers. That trust is backed by real improvements — cloud platforms now offer stronger visibility, default encryption, and built-in threat detection that help teams stay ahead of risks. Security and compliance, including HIPAA-compliant cloud for SaaS, are now baseline expectations when evaluating cloud options.

Security has become one of the cloud’s key strengths. While misconfigurations and user-side errors still happen, the underlying infrastructure provided by AWS, Azure, and Google Cloud is now widely seen as secure and enterprise-ready.

Each of the major cloud providers offers built-in tools to help safeguard data, accounts, and workloads:

AWS includes services like AWS Shield for DDoS protection, Amazon GuardDuty for threat detection, and AWS KMS for managing encryption keys.

Google Cloud encrypts all data by default—both in transit and at rest—and integrates security throughout its infrastructure.

Microsoft Azure offers protections like Azure DDoS Protection, Microsoft Defender for Cloud for threat detection, and Azure Policy to enforce compliance standards.

In short: all three platforms offer strong out-of-the-box security. What matters most is how teams configure and monitor their environments.

For more details on healthcare compliance, you can review each platform’s official HIPAA documentation: AWS HIPAA Compliance, Azure HIPAA Compliance, and Google Cloud HIPAA Compliance.

Which Has the Best Features?

AI, analytics, and serverless computing are now front and center in the cloud wars. All three major platforms — AWS, Azure, and Google Cloud — are racing to stand out with smarter, faster, and more flexible tools for developers and data teams.

AWS continues to lead the cloud market when it comes to service depth and pace of innovation. Each year, it rolls out hundreds of new features — many aimed at helping developers and data teams work smarter with machine learning, analytics, and cloud-native tools.

Its flagship platform, Amazon SageMaker, supports the full machine learning lifecycle — from building to training to deploying models. And with Amazon Bedrock, developers can now build generative AI applications using powerful foundation models — all without managing any underlying infrastructure.

For specific use cases, AWS offers tools like Rekognition for image analysis, Polly for text-to-speech, and Lex for chatbot development. AWS Bedrock is now a core platform for generative AI, supporting top foundation models from Anthropic (Claude), Meta (LLaMA), Cohere, and Stability AI. It’s widely used in SaaS products for building intelligent assistants, chatbots, and other AI-first experiences — all without managing underlying infrastructure.

Microsoft’s Azure OpenAI Service is deeply integrated with tools like GitHub, Power Platform, and Microsoft 365. Developers can embed GPT-4, DALL·E, and Codex into apps with just a few lines of code, making it ideal for SaaS products built around natural language, automation, or copilots.

It’s a fast way to embed natural language processing, image generation, or even code completion into products. For more traditional workflows, Azure Machine Learning offers tools for training, managing, and monitoring ML models—plus built-in features for responsible AI use.

Google Cloud’s Vertex AI now integrates Gemini — its multimodal AI model — enabling SaaS developers to build rich chat assistants, visual search tools, and content generators from one unified platform. It’s especially powerful when paired with BigQuery, Looker, and open-source frameworks like TensorFlow. If your SaaS product is analytics-driven or AI-first, Google Cloud’s tooling can give you a strong edge.

Which Offers the Best Support?

AWS has good reviews on TrustRadius. It offers quick and responsive customer support.

Regarding the Azure customer experience, Gartner states, “Customers cite issues with technical support, documentation, training, and breadth of the ISV partner ecosystem.”

Google Cloud has expanded its enterprise support with Premium Support, a service designed to meet the needs of large-scale customers through faster response times, technical account managers, and proactive operational guidance.

Which is Cheaper for Startups?

The startup sector is full of opportunity, especially with the growing demand for tools in AI, big data, DevOps, and cloud-native development. When you’re building a SaaS company, choosing a cost-effective cloud provider is one of the most important early decisions you’ll make. In this section, we’ll also look at a quick cost comparison of AWS, Azure, and Google Cloud for SaaS apps to help you evaluate which provider aligns best with your budget.

Comparing pricing models across AWS, Azure, and Google Cloud can be tricky, though — each has different billing structures, discounts, and incentives. The good news? All three offer generous free tiers and startup credit programs to help early-stage companies get started without a heavy upfront investment.

AWS Pricing Model

The scalability is much evident in its cost management or pricing options: Pay As You Go, Save When You Reserve, and Pay Less By Using More. AWS allows businesses not to overcommit, which may eventually hurt their budget. There are volume-based discounts, or price tiers, to help businesses get more savings should they need more capacity.

AWS Free Tier allows users to explore more than 85 products as well as build on AWS. There are three different types of free offers: Always Free, 12 Months Free (for new accounts), and short-term trials. For startups, the AWS Activate program provides up to $100,000 in cloud credits, along with technical support, business training, and access to AWS experts. It’s a strong offering for early-stage teams looking to build and test quickly.

Microsoft Azure Pricing

Microsoft Azure also offers a flexible approach to pricing, particularly if you’re already using tools like Microsoft 365 or GitHub. Through the Microsoft for Startups Founders Hub, eligible companies can receive up to $150,000 in Azure credits, plus access to GitHub Enterprise, Microsoft 365, and technical mentorship.

One key benefit of this program is that it doesn’t require you to have existing funding or VC backing to qualify. It’s a great option for bootstrapped founders or product teams getting started from scratch.

Google Cloud Platform Pricing

Google Cloud for Startups offers up to $350,000 in credits for eligible companies, though access to the highest tiers often requires affiliation with a recognized accelerator, incubator, or VC partner. Direct applications may qualify for lower-tier credit packages.

Google Cloud is especially well suited for data-driven or AI-first products, thanks to services like BigQuery, Vertex AI, and seamless integrations with open-source tools. While its headline pricing may be slightly higher for certain workloads, the available credits and performance efficiency can more than offset those costs—especially for early-stage teams focused on analytics or machine learning.

The Winner?

All three platforms provide real value for startups. The “cheapest” option will ultimately depend on your product’s technical needs and the tools your team already uses.

AWS continues to lead in service depth and startup support. Azure is a smart choice for teams already using Microsoft tools or services. Google Cloud offers the largest credit package and is a strong contender for AI-heavy or data-intensive applications.

However, this cost could be different if you combine it with offers that are offered by different incubators. Technology Rivers offers cloud credits to its customers.

Final Verdict: Best Cloud Platform for SaaS Hosting

Choosing the right platform — and understanding which cloud provider is best for a SaaS platform in 2025 — is crucial to building a resilient SaaS architecture on cloud. Rather than one emerging as the clear victor, selecting a provider is more about ‘horses for courses.’ Each has advantages in different situations. Luckily, unlike riding a horse, you don’t have to choose just one.

Multi-cloud is the norm, and leveraging multiple cloud providers and resources is the best path for many organizations. According to Flexera’s 2025 State of the Cloud report, 89% of enterprises now use a multi-cloud strategy, and 80% combine public and private cloud environments. Today’s focus is shifting toward workload portability, AI model deployment flexibility, and cloud-native observability.

After all, the preferred cloud vendor will still depend on the budget and business requirements. Azure will be best for companies that heavily rely on Microsoft products. AWS offers the widest selection of cloud services, and it has a global reach. GCP has flexible pricing models and is great for companies that use web-based applications.

However, if we were to choose only one cloud provider for cloud development projects, then we would personally recommend Amazon Web Services for SaaS.

When it comes to cloud services, AWS is the proverbial 800-pound gorilla. Few might even remember that Amazon.com was once an online bookstore. In developing AWS, the company is credited with also developing the entire concept of cloud computing as an industry. As of late 2024, AWS maintains a leading 31% market share in cloud infrastructure, followed by Microsoft Azure at 24%, and Google Cloud at 12%, according to Synergy Research Group.

AWS was an early pioneer in the cloud computing space and continues to lead innovation. In particular, serverless functions are another area where AWS recently blazed trails with AWS Lambda.

Microsoft Azure has been the second top cloud service provider. Many enterprises already deploy Windows and other Microsoft software, which significantly contributes to Azure’s success. It is best for Microsoft stack dev (.NET, MS SQL Server). It works for others, too, but this is where AWS excels.

Google Cloud Platform is still catching up with its two competitors, but Google Cloud Platform is often cited as a world leader in the field of artificial intelligence. Google Cloud offers the AI Platform, a fully managed, end-to-end platform for data science and machine learning.
