According to the latest Gartner forecast, worldwide end-user spending on public cloud services is expected to reach $494.7 billion in 2022 and surpass the $600 billion mark in 2023.
Businesses are adopting cloud computing services because they offer valuable insights into go-to-market approaches, partnering tactics, alliance and acquisition strategies, investments, and best operational practices.
If someone asks me what cloud computing is, I try not to get bogged down with definitions. I tell them that, simply put, cloud computing is a better way to run your business. (Marc Benioff, Salesforce).
Having started in the 1960s, cloud computing has come a long way. To date, it’s no longer a question of whether to opt for cloud computing or not - nowadays, the main question is which cloud platform to go for. The global cloud computing market is flooded with numerous cloud providers, although AWS, Azure, and Google Cloud Platform stand out in the top three, dominating the public cloud landscape and providing safe, flexible, and reliable cloud services. These top companies hold a commanding lead in the IaaS (infrastructure as a service) and PaaS (platform as a service) markets.
How do you decide which one of these cloud vendors to choose? Keep reading to look at the most significant pros and cons of these three cloud giants and fully understand their capabilities and differences to choose the cloud service provider best suited to your needs.
AWS vs. Azure vs. Google Cloud. Market Shares And Growth Rate of Cloud Giants
The pandemic has accelerated the adoption of cloud computing over the last few years, and we can see the figures growing, meaning the crisis was more a long-term booster for the cloud market than a short-term effect. According to Flexera’s report, companies are investing heavily in cloud services, and consumption of private, public, or hybrid cloud approaches continues to expand across all industries.
To date, the global cloud market is dominated by three major cloud providers sharing 64% of the market:
- Amazon Web Services or AWS;
- Microsoft Azure;
- Google Cloud Platform (GCP).
Amazon Web Services (AWS) grows 40% annually and leads the cloud infrastructure services market, according to 33% of total spending. Meta (previously Facebook) recently chose AWS as a long-term strategic cloud service provider as it begins to move away from social media to become a broader metaverse company over the next five years. AWS also announced key customer wins across healthcare, retail, and financial services.
Microsoft Azure has a 22% market share and remains the second largest cloud service provider, growing 46% annually, driven by long-term consumption commitments. In 2017, this cloud provider only had an 11% market share and doubled its position in a very short timeframe. Azure continues to grow its cloud business across multiple sectors, with key wins in the healthcare and financial services sectors. According to Microsoft CEO Satya Nadella, the number of $100 million-plus Azure deals more than doubled year over year, and the company is seeing consumption growth across all industries, customer segments, and geographies,
Google Cloud Platform (GCP) is the third cloud provider, accounting for 9% of the market. According to Alphabet's recent financial report, Google Cloud sales jumped from $4.05 billion in Q1 2021 to more than $5.82 in Q1 2022, with a 44% cloud revenue growth rate. Available to the public since 2010, the Google Cloud Platform now offers over 100 services spanning computing, networking, big data, and others. GCP is the smallest of the top 3 cloud providers compared to AWS and Azure. However, it offers a robust set of cloud services to power and supports any type of application. The industry-leading tools in deep learning, artificial intelligence, machine learning, and data analytics are also among the significant advantages of this cloud services provider.

AWS vs. Azure vs. Google Cloud. Pricing
Line-of-business leaders everywhere are bypassing IT departments to get applications from the cloud and paying for them like they would a magazine subscription. (Daryl Plummer, Gartner).
One of the key reasons organizations worldwide are moving to the cloud is the desire to save money. Indeed, cost savings is one of the main benefits of cloud computing that attract more and more companies every year. According to Flexera’s report, 94% of enterprises use the cloud, while cost reduction is one of the top reasons businesses choose to adopt the cloud.
By using cloud infrastructure, you don’t have to spend much on purchasing and maintaining equipment that significantly reduces CAPEX costs and Total Cost of Ownership. With cloud computing services, you don’t have to invest in hardware, utilities, facilities or a large data center to grow your business. Additionally, you don’t need large IT teams to handle the cloud data center operations, as you can make the most of the experience of your cloud provider's staff. Another advantage of cloud computing is that the downtime risk is minimal, so you don’t have to spend time and money fixing this problem.
Comparing the top 3 cloud providers, let’s look at the pricing options they offer to the customers. The pricing of the cloud platform usually depends on:
- Customer requirements;
- Cloud services used.
AWS, Azure, and GCP offer their customers competitive pricing plans with additional cost management options, such as budgets, reserved instances, and resource optimization, available to all users.

Maximum Instance: The largest instance offered by this cloud vendor includes 3.89 TB of RAM and 128 virtual CPUs and will cost you around $3.07/hour.
Besides this, AWS recently started offering pay-per-minute billing. It also provides customers a one-year free trial and a discount of up to 75% for a 1-3 years commitment. There are three payment options available on AWS:
- No up-front;
- Partial up-front;
- All up-front.
AWS services also come with cancellation available. The platform offers to sell your products on the marketplace.
Minimum Instance: The smallest instance of this platform includes 2vCPUs and 8 Gb of RAM, which will cost you around $70/month.
Maximum Instance: The largest instance offered by Azure includes 3.89 TB of RAM and 128 virtual CPUs. It costs around $6.79/hour.
Like AWS, Azure also offers customers pay-per-minute billing and up to 72% discount for a commitment ranging from one to three years. The cancellation is available but will cost you a 12% cancellation fee. Azure offers only one - all up-front payment option for customers.
Google Cloud Platform
Minimum Instance: The most basic instance offered by GCP provides customers with 2 virtual CPUs and 8 Gb of RAM at a 25% cheaper rate compared to AWS and Azure. Thus, this platform's minimum instance will cost you around $52/month.
Maximum Instance: In the case of the largest instance, GCP takes the lead, offering 3.75 TB of RAM and 160 vCPUs at around $5.32/hour.
In contrast to pay-per-minute billing offered by AWS and Azure, GCP offers users a pay-per-second billing model, allowing them to save much more. Besides this, GCP also provides various discounts to help customers save up to 50% in some cases when compared to AWS. This platform offers a Committed Use Discount (CUS) for one year up to 37% or for three years up to 55% and Sustained Use Discount (SUD) for up to 30%. Apart from a SUD, Google Cloud Platform offers a credit of $300 for 12 months. GCP services come with no cancellation available and with only no up-front payment option.
|Instance Type||AWS||Microsoft Azure||GCP||AWS (per hour)||Microsoft Azure (per hour)||GCP (per hour)|
|Compute optimized||c6g.xlarge||F4s v2||c2-standard-4||$0.136||$0.169||$0.208|
|Memory optimized||r6g.xlarge||E4a v4||m1-ultramem-40||$0.202||$0.252||$6.293|
|Accelerated computing||p2.xlarge||NC4as T4 v3||a2-highcpu-1g||$0.90||$0.526||$3.678|
Discounted Pricing for 1-Year Commitment (No Upfront Cost)

|Accelerated computing||p2.xlarge||NC4as T4 v3||a2-highcpu-1g||$0.614||$0.3093||$2.313|
- For GCP, on-demand pricing of memory-optimized instances was the highest, but the 1-year commitment price is the lowest among all three cloud providers.
- GCP is also much cheaper than AWS and Azure for computing optimized cloud-based instances, although it’s more expensive when it comes to the instance types of accelerated computing.
- The general-purpose instances for AWS and Azure are almost similar for 1-year committed plans.
Serverless Pricing Comparison
All the three cloud platforms offer users serverless services:
- AWS Lambda;
- Azure Functions;
- Google Cloud Functions.
For the computing power you use, these cloud vendors charge you in 100-millisecond increments, allowing you to focus on the code and event triggers while serverless providers will do the rest. With serverless computing, you only pay for the time your code runs without having to pay for reserving CPU Cores and RAM of the underlying EC2 instances or virtual machines. The total cost of serverless computing for all three cloud providers is calculated below.
For better understanding, let’s consider the hypothetical scenario where you allocated 512MB of memory to your function, executed it 4 million times per month, and ran for one second each time.
AWS Lambda Pricing
Monthly compute charges:
- The monthly compute price is $0.00001667 (GB-s).
- The free tier provides 400,000(GB-s).
- Total compute (seconds) = 4M * (1s) = 4,000,000 seconds.
- Total compute (GB-s) = 4,000,000 * 512MB/1024 = 2,000,000 GB-s.
- Total compute – Free tier compute = Monthly billable-compute GB-s.
- 2,000,000 GB-s - 400,000 free tier GB-s = 1,600,000 GB-s.
- Monthly compute charges = 1,600,000 * $0.00001667 = $26.67
Monthly request charges:
- The monthly request price is $0.20/1 million requests.
- The free tier provides 1M requests per month.
- Total requests – Free tier requests = Monthly billable requests.
- 4M requests – 1M free tier requests = 3M Monthly billable requests.
- Monthly request charges = 3M * $0.2/M = $0.60.
Total price per month for AWS Lambda = Compute charges + Request charges = $26.67 + $0.60 = $27.27
Azure Functions Pricing
|Resource consumption (seconds)||Resource consumption (GBs)||Billable Resource||Monthly resource- consumption price:||Execution billing:||Monthly execution price:|
|Execution number = 4 million executions.||Resource consumption in GBs = 512 MB / 1,024 MB = 0.5 GB.||Resource consumption = 2M GBs.||Billable resource consumption = 1.6M GBs.||Total monthly execution = 4M executions.||Monthly billable execution = 3M executions.|
|Execution duration = 1 second.||Execution time (seconds) = 4 million seconds.||Monthly free grant = 400,000 GBs.||Resource-consumption price = $0.000016/GB.||Monthly free executions = 1M executions.||Price per million execution = $0.20.|
|Total resource consumption = 4M executions * 1 second = 4M seconds.||Total consumed GBs = 4M seconds * 0.5 GB = 2M GBs.||Total billable consumption = 2M GBs – 400,000 GBs = 1.6M GBs.||Total monthly resource-consumption cost = 1.6M GBs * 0.000016/GB = $25.60.||Total monthly billable executions = 4M executions – 1M executions = 3M executions.||Monthly execution cost = 3M executions * 0.20 = $0.60.|
Total price per month for Azure Functions = $25.60 + $0.60 = $26.2
Google Cloud Platform
|Invocation||Per second usage||Invocation||GB-second||GHz-second|
|(512 MB / 1024 MB) * 1 second = 0.5 GB-s per invocation. For 512 MB, Google cloud offers an 800MHz CPU. So, GB-seconds would be: (800 / 1000) * 1 second = 0.8 GHz-second per invocation.||4M executions * 0.5 GB-s = 2M GB-s per month. 4M execution * 0.8 GHz-s = 3,2M GHz-s per month. GCP offers a free tier of 2M invocations, 400,000 GB-seconds, and 200,000 GHz-seconds per month.||4M – 2M = 2M execution * $0.0000004 = $0.8.||2M – 400,000 = 1,600,000 * $0.0000025 = $4.||3,2M – 200,000 = 3M * $0.0000100 = $30.|
Total price per month for Google Cloud Functions = $0.8 + $4 + $30 = $34.8
- AWS and Azure have almost the same monthly price, and this is a result of the high free-tier offerings they provide.
- Google Cloud Functions offer the lowest price for GBs consumed per second, along with free-tier offerings. The platform has the highest price per month due to the additional cost associated with MHz CPU performance.
Strengths And Weaknesses of the Platforms. How to Choose the Best Cloud Vendor?
Amazon Web Services
