AWS vs. Azure: The Public Cloud Comparison
In comparing public cloud providers Amazon Web Services (AWS) and Microsoft Azure, it’s clear both offer almost the same levels of security, scalability and reliability. Nearly three quarters of businesses plan to optimize their current use of the public cloud to avoid the expensive undertaking of building and managing physical data centers, including stacking servers, design disk storage arrays, Ethernet switches, and firewalls.
With similar offerings it boils down to choosing the best cloud computing vendor for your business. Is it going to be the largest cloud computing platform, AWS, or the fastest growing one, Azure?
Let’s dig deep and define AWS and Azure: the benefits they offer, a multi-parameter comparison, and guidance to help you choose the right cloud platform for your business.
What is AWS?
Amazon Web Services, aka AWS, is a public cloud service platform from Amazon that provides services in different domains, such as compute, storage, delivery, database, migration and security that help businesses scale and grow. The services are broadly classified into — infrastructure as a service (IaaS), software as a service (SaaS) and platform as a service (PaaS).
However, Elastic Cloud Compute (known as Amazon EC2) and Simple Storage Service (Amazon S3) are two AWS services that have made Amazon a $130 billion cloud market leader. EC2 provides virtual machines that can be used as real computers, letting users develop and deploy applications without the need to deploy, manage, and support hardware locally. Amazon S3 is an object-based storage solution with basic data management features.
AWS has millions of customers spanning across 200 countries. Offering 76 availability zones in which servers are located, AWS has empowered businesses to set geographical limits on their services and more importantly, ensure security by storing data on servers that are geographically redundant from each other. It’s no surprise AWS is a heartthrob among fast growing startups, large enterprises and leading government agencies who are always looking to bring down costs and drive faster innovation.
Benefits of AWS
When you move your businesses to AWS, you enjoy a cloud ecosystem that is every bit customer-centric, and with that comes a host of benefits.
AWS offers low, pay-as-you-go pricing with no up-front expenses or long-term commitments. You do not have to pay for all the AWS services, you pay for what you need and use (resources, storage and bandwidth), and the costs are scaled accordingly. With the low price of entry and the fact that maintenance is taken care of by Amazon, the ripple effect leads to an overall reduction in operational costs.
Scalable and adaptable
Amazon runs on an infrastructure that scales based on your usage. You can deploy new applications, quickly scale up workloads when the demand is high and scale down when the demand is light. Whether you need one virtual server or several, for an hour or 24/7 – AWS gets you what you want and you pay only for what you consume.
Open and flexible
The level of customization offered by AWS allows you to experiment with the latest technology and innovate faster. AWS on its own has innovated and created new technologies to transform business. For instance, there’s AWS Lambda, which lets developers run their code without the administrative overhead of provisioning and managing servers.
AWS comes with industry-recognized certifications and audits which include PCI DSS Level 1, ISO 27001, FISMA Moderate, FedRAMP, HIPAA, and SOC 1 and SOC 2 audit reports. Moreover, AWS data centers have multiple layers of operational and physical security to ensure data is safe. AWS has tried to keep its data centers as hidden as possible, locating them in out-of-the-way locations and allowing access only on an essential basis.
What is Azure?
Microsoft Azure (previously called Windows Azure until2014) is a cloud computing platform developed by Microsoft to help IT professionals build, deploy and manage applications. Azure provides services in different domains such as compute, storage, delivery, database, migration and security which help businesses scale and grow. They are broadly classified into – infrastructure as a service (IaaS), software as a service (SaaS) and platform as a service (PaaS).
Azure hosts multiple data centers and delivery points, enabling fast content delivery. Businesses can store any data type and share it across virtual machines (VM), at the same time, it supports the development, testing, deployment and management process – all without breaking a sweat. That’s the reason why 95 percent of Fortune 500 companies trust their business on Azure.
Benefits of Azure
There is more than one reason why behemoths like 3M and BMW love Azure.
You do not have to pay for all the Azure services, you pay for what you need and use (resources, storage and bandwidth), and the costs are scaled accordingly. You do not have to put in the initial investment for offsite data centers. The icing on the cake: you save money on service calls and warranty renewals, reducing operational costs.
Azure lets you spin up new services in a jiffy, scaling your storage capabilities. Use services like BASH, PowerShell, or REST APIs to quickly automate time-consuming repetitive tasks to speed up your app delivery, leaving more time to focus on other important tasks. The level of autonomy makes Azure a tempting solution for businesses of any size.
If you are already using a Windows server, integrating Microsoft applications becomes effortless. Azure has successfully created a rich integration ecosystem offering end-to-end solutions from development to deployment of a tool. It essentially unifies unit testing, integration testing, delivery and pretty much everything in between.
Azure provides some of the most advanced security technology and adheres to compliance including FERPA, IRS, HIPAA, and GDPR. Your data is protected with tools like Threat Intelligence, Advanced Threat Analytics, Azure Information Protection, and multi-factor authentication.
