Top IaaS Providers

Infrastructure-as-a-service (IaaS) is a cloud-based, on-demand solution where a third-party vendor provides server management, data storage, and networking resource solutions to its clients.

An IaaS provider handles everything, so businesses don’t have to play administrator and waste time on all the technicalities of managing a cloud server. All that remains for businesses is setting up and managing the cloud infrastructure to run it in alignment with their organizational needs. 

Enterprises go for an IaaS provider for easy accessibility, higher scalability, and reduced operational costs. In fact, adoption is indeed picking up the pace. Though SaaS remains the leading segment in cloud computing, IaaS is the fastest-growing cloud service in terms of revenue, with a 33.7% five-year compound annual growth rate (CAGR). According to forecasts, the market size of IaaS will grow to $201.81 billion by 2027. 

Though IaaS is being widely adopted today, there is always something new you could learn about the technology. Here, we have listed the core features, benefits, and use cases of an effective IaaS solution. And we compare the top IaaS providers, so you can determine which functions best in conjunction with your specific needs:

Features of IaaS

Features of IaaS can be broken down into three main components. Namely compute, network, and storage. These functionalities allow users to build their own customized systems, making them as complex and powerful as they need, all with the ability to scale up and down as required. 


The concept of IaaS computing begins with servers. Servers are powerful systems or computers that usually have several CPUs, hundreds of gigabytes of RAM, and thousands of gigabytes of storage. They are very expensive to acquire and hard to maintain. An IaaS service provider maintains data centers that house many of these physical, bare-metal servers. One can partition these physical servers into smaller virtual machines by using a hypervisor. These virtual machines can independently run their operating systems and applications, while drawing power from a bare-metal server. 

Computation services also include optional features, such as load balancing, where the system remains load free because of automatically distributing the network traffic. Users get to choose the operating system while purchasing a virtual machine from an IaaS provider. They can also scale vertically and add more CPU if the VMs don’t have enough processing power or customize to handle more load. 


Storage options can be divided into three segments: file storage, object storage, and block storage.

  • File storage stores data as a single entity in the file. These storage files can co-exist or exist within each other as other data in a hierarchical order. 
  • Similarly, object storage takes saved data as a single entity but also attaches metadata and an identifier to it. Object storage is generally used to store whole objects over the network, such as image files, logs, or HTML files. Object storage is the most favored alternative, as it is cost-effective and easy to use.
  • Block storage is a relatively familiar storage option that enables over the network access to a block storage device and links it to a virtual machine. Block storage saves data as blocks of actual bytes or bits. It has certain advantages over object or file storage, like faster data transmission though it is not as user friendly.


The network function interacts and connects all components, including the storage function, containers, VMs, servers, the internet, and the intranet. Networking ensures that information is transferred through the architecture regardless of endpoints. Depending on the amount of data that needs to be transmitted for computing, users may require higher networking bandwidths.

Benefits of IaaS

Higher performance, lower expenditure

One of the most notable benefits of IaaS is a prompt increase in organizational performance. IaaS technology opens your infrastructure to expert support provided by an IaaS cloud service provider of your choice. CSPs have a more reliable and robust infrastructure framework in place, which would be much more feasible and realistic than managing everything in the office environment.

This implies that with IaaS, you have the opportunity to save upfront costs associated with acquiring, maintaining, and operating hardware. This ultimately decreases the overall capital expenditure or IT spending, while businesses can achieve higher performance levels on the existing infrastructure. 

IaaS allows in-house IT teams to focus on achieving business goals and objectives rather than upgrading to the latest hardware or maintaining the infrastructure. With an SLA, you can ensure that incorporating IaaS gives you the best performance from your cloud provider’s infrastructure. It obliges your cloud provider to continuously upgrade features and functions on their end to provide the best possible service. 

Increased security

IaaS involves managed information security as a critical element in addressing security concerns within the infrastructure. A cloud infrastructure exposed to threats can put all operations at risk. As IaaS cloud service providers deal with huge amounts of data, they are known to make significant investments to strengthen their IT security features, so you may trust them with your data. They also leverage strict access guidelines for both physical and virtual locations and incorporate multiple forms of authentication.

IaaS also involves advanced information security features, including end-to-end encryption, CASB, IDS/IPS, intrusion detection. This gives your organizational data a higher level of security and protection as compared to hosting on site. However, it is vital to determine your security requirements and know and compare security policies and the available measures for data protection while choosing an IaaS provider. 

Scalability and flexibility

The attribute of high scalability and flexibility make IaaS future proof and capable of serving as a durable solution. IaaS technology enables you to scale your business up or down, on demand, based on the requirements, at any given time. For instance, if your business decides to host a digital campaign that drives more traffic to your website than usual. In this case, IaaS can allow your business infrastructure to handle the increase in traffic through procedures, like automatic provisioning of resources.

Moreover, when your business expands or multiplies to new locations, you won’t have to invest time and funds to initiate new hardware or infrastructure components. You can simply virtually connect to your cloud infrastructure and continue operations as usual. IaaS gives growing businesses and their IT infrastructures enough flexibility to expand freely and with minimal disruption.

Reinforced disaster recovery and business continuity

IaaS cloud computing prepares your enterprise cloud infrastructure for the worst-case scenarios. For most businesses, it would be almost impossible or extremely expensive to recover from a failed cloud infrastructure. Most IaaS cloud service providers host their data and equipment in highly secure environments, which are constantly available. 

These purposefully built data centers have all the resources to preserve the infrastructure, such as uninterrupted power, cooling systems, and reliable network connectivity. On the other hand, office-based deployments have several other processes and cannot maintain their data centers efficiently.

Minimal downtime is another benefit of IaaS just because everything is hosted on the cloud. Constant availability and remote access make it possible for the business to remain productive from any location in the face of any calamity, hence saving precious uptime. 

IaaS use cases

Rapid testing and development: As a part of the development pipeline, IaaS enables IT teams to rapidly create, test, and develop environments automatically to bring new applications to market faster. 

Run and deploy web applications: IaaS fulfills all infrastructure requirements to run large-scale web applications, including storage, servers, and networking functions. It also enables speedy web application deployment and easy application scaling. 

Easy storage, backup, and recovery: IaaS helps organizations respond to storage requirements on-demand while managing data, maintaining backup and recovery systems, and complying with legal and regulatory requirements. It helps save up on the upfront cost of managing data. 

Enabling high-performance computing: IaaS allows organizations to leverage HPC as a part of their service, which is otherwise a hefty investment. Businesses can solve complex problems involving countless variables and calculations with the help of supercomputers or clusters of computers. 

Big data analytics: Big Data processing requires a complex infrastructure involving high-speed databases, distributed processing engines, and extensive storage systems. IaaS providers make all this infrastructure available as a service, along with features like machine learning and AI. 

What to look for in IaaS providers

Considering the type of business and processes you represent is the first step when it comes to evaluating IaaS providers. Get input from multiple departments and make sure all issues and concerns are considered before making a decision. Identify key features that you expect from the infrastructure service that address all your concerns. Here are several key factors that you need to ensure while selecting an IaaS provider.

  • Customizability and data portability
  • Well-defined infrastructure migration
  • Dependable SLA
  • Security and regulatory requirements
  • Data center expertise
  • Unbiased recommendations

Lastly, maintain a transparent relationship with your service provider and define your needs clearly. All this considered, your cloud infrastructure will be ready to bring optimal results to your organization.
