We list the best IaaS providers, to make it simple and easy to customize your virtual infrastructure to deliver maximum benefit at minimum cost.
In the internet’s early days, it was much more difficult to build your own web service. You had to buy and maintain your own servers or enter binding long-term contracts with data center operators. This arrangement was inconvenient for most businesses, and the costs were high, meaning people weren’t too willing to take risks. However, cloud computing providers changed the game.
Cloud computing platforms operate servers and rent them to customers on demand. There’s no need to sign any long-term contract, as you only pay for what you use. Anyone can now host their cloud-based app conveniently and affordably. This arrangement is known as Infrastructure as a Service (IaaS).
You can rent a server from an IaaS provider and run any operating system or application you want on it. You can decide which locations to rent from to ensure proximity to your users, which, in turn, delivers faster speed.
We tested different IaaS providers to identify the best ones. We narrowed our list based on important factors including pricing, features, performance, ease of use, customer support, etc. The platforms we selected have their pros and cons, but are, overall, the best ones you can choose to host your websites and apps.

Best IaaS provider FAQs
How to choose an Iaas provider
Cost
Cost is the main consideration when choosing any service. You should choose an IaaS provider that you can afford in the long term to avoid troubles. Different providers have different pricing structures, so study them to identify any potential problems. For instance, some hosts are affordable in the beginning but become costlier as you scale. Always read the fine print to have the full picture of how the pricing works.
Performance and Reliability
Your IaaS provider must be a reliable one. You don’t want something that goes down frequently and causes you to lose money. The servers you rent should also deliver solid performance and make your website or online app load as quickly as possible.
The larger the data center network of your cloud provider, the better their reliability and redundancy. Performance depends on what type of servers they use and the proximity to your users.
Customer Support
Nothing is perfect including IaaS providers. Things can go wrong at any time, and you’ll likely need customer support. You should be able to contact a human support representative from your IaaS host to help you solve your issues. The host should also provide complementary support resources such as FAQs, user guides, video tutorials, and extensive documentation.
What are the essential features of an IaaS provider?
1. Pay-As-You-Go
The main benefit of IaaS providers is that you don’t have to sign any long-term contracts to rent computing resources. You can just select the ones you want and pay as you go. You only pay for what you use, which makes it convenient and more affordable.
2. Scalability
You should be able to scale your computing needs with ease. Your IaaS provider should handle your increasing data storage and computing needs without hassle. You just need to select the additional resources you need and deploy them.
3. Security
You’ll be uploading sensitive data to your IaaS provider, so it should have sophisticated security features to prevent data leaks and theft. Losing customer data could lead to costly fines and lawsuits and losing sensitive business data could make you lose your competitive advantage.
4. Virtualization
Virtualization means creating virtual versions of computers or servers. One server can host several virtual machines, with each machine acting like its own separate server with distinct features. Your IaaS provider should let you deploy virtualized computing instances to support your app.
More on IaaS
Investing in your own IT infrastructure is a significant cost, regardless as to whether you're a startup or an expanding business.
It's not just the servers, but all aspects of your network that you will need to buy, and for some companies this can be prohibitive to growth. Even worse is that after a few years this hardware will need replacing as an additional cost.
However, advances in cloud computing mean that an alternative that is now available: Platform as a Service (PaaS), in which a supplier already has their own servers and networks, and you simply rent the resources you need.
The big advantage is that pricing is much less than if you bought your own hardware, making it much easier for small companies to set up an extensive and professional IT infrastructure at the fraction of the cost.
Additionally, because you are only paying for what you need, there's no over-spend required for redundant systems, as IaaS is fully scaleable for as and when you need it.
