This brief guide will shine a light on the competition and services between the two market leaders in cloud services. The market is dominated by AWS (the largest single player) with a 33% market share. Microsoft Azure has only held a 21% share until Q4 2021 (up 9%). Whereas, Google Cloud Platform only holds 10% of the market.  

Azure Cloud Services 

Azure Cloud Services aids in the management of applications through Microsoft-operated data centers. The platform provides seamless services like analytics, computing, networking, and storage. Its extensive toolkit is constantly growing and competing in the market with a global footprint. 

Amazon Web Services (AWS) 

AWS is a subsidiary of the eCommerce and technology behemoth Amazon. It has 200+ services from its globally established data centres. The pricing model and its optimized costs enable users across start-ups, large enterprises, and leading global agencies to adopt AWS. 

 Where the difference lies? 

Gartner published a document that stated, "Public cloud services, such as Amazon Web Services (AWS), Microsoft Azure, and IBM Cloud, are innovation juggernauts that offer highly operating-cost-competitive alternatives to traditional, on-premises hosting environments." 

 AWS Azure
Data warehouse  Amazon Redshift Azure Synapse Analytics 
Availability25+ regions worldwide 60+ regions worldwide 
Computing Elastic computing (EC2) Virtual machine 
Services 200+200+ 
PaaS Elastic beanstalk App services 
Security AWS Identity & Access ManagementAzure Active Directory 
Serverless AWS Lambda Azure function 
Containers AWS Elastic Containers Azure Kubernetes Services (AKS) 
Rational database  AWS RDS Azure SQL 

While both provide similar services, there is a certain differentiation factor as well. These can be segregated in terms of computing power, pricing, provisioning, computing, storage, features, and adaptability. 

1. Computing power, provisioning, and usage 

Scalability is one of the core elements of cloud computing. For Azure, users can create VMs from Virtual Hard Disks (VHD). It enables load balancing and uses virtual scale sets to ensure scalability. On the other hand, AWS uses EC2 instances in which the resource footprint may increase or shrink on demand. Users may constrict their virtual machines (VMs), which are pre-configured and users can modify them in terms of power, size, and memory. 

Service AWS Azure 
 Amazon Ec2 Instance  Azure Virtual machines
Computing powerVMware Cloud of AWS  Azure VMware Solution
 AWS Parallel Cluster Azure Cycle Cloud 

In both virtual machines and servers, you can manage the OS. In both, users pay according to demand. The key differentiation is that EC2 may be customizable for various uses, whereas Azure Virtual Machines (VMs) can merge with other cloud deployment applications, even from third-party tools. 

2. Storage 

AWS and Azure both offer tier-based object storage. particularly directed at protecting stored data. AWS has S3 and Azure offers Azure Cool Blog Storage, both designed for infrequently accessed workloads. In terms of storage, both AWS S3-IA and Azure CBS are best for clod-tier or infrequently-accessed data loads where performance and latency are the keys. 

Both offer reliable storage services ideal for long-term usage, backup, and DR. However, there are certain differences in regional availability, pricing, and security features. 

3. Pricing – Comparing apples to apples 

The objective of pricing comparison isn’t necessarily to make a decision between service providers but to identify where costs can be saved by using the same services from different providers. Truth be told, AWS has different pricing models, but they’re complex enough to give bill-related surprises. Dedicated tools like AWS Cost Explore, AWS Calculator, and trusted advisors are developed for cost optimization. whereas Azure’s pricing strategy is easier to understand.

 6. Data Warehouse 

A data warehouse is a central repository for information that is extracted from multiple internal and external sources for business intelligence. The typical functionalities support data analysis, reporting, and business intelligence. The cost and technical capabilities depend on the vendors, but most data warehouses share the same traits. Compared to legacy systems, modern cloud-based data warehouse systems are agile enough to support today’s data and business intelligence requirements. Major vendors have multiple on-prem and cloud-based solutions. 

Amazon and Microsoft are two of the main players in cloud computing, followed by Google and others. Amazon Redshift is a cloud-based data management system, which allows petabytes of semi-structured and structured data in little time.
