Picture a software enterprise’s IT team finalizing a new product, only to discover their on-site IT infrastructure can’t handle beta testing. Or a fintech company facing compliance fees, experiencing repeated breaches, and falling behind due to outdated security systems.
In these scenarios, rapid scaling can provide instant relief and a chance to catch up without losing revenue. Unfortunately, the traditional computing model doesn’t support rapid scaling. That’s where the Infrastructure as a Service (IaaS) model comes in.
Let’s discover how IaaS works, explore its benefits and use cases, and discuss factors to consider when choosing a provider.
What is the IaaS cloud model?
IaaS is a shared-responsibility cloud computing model through which third-party partners provide and manage IT infrastructure solutions while companies install, configure, and manage their software.
The traditional IT model requires organizations to build and maintain expensive on-site storage systems, network resources, and physical equipment. This infrastructure is incredibly costly to maintain, difficult to scale, and vulnerable to risks—especially for multi-location enterprises.
IaaS is a welcome solution to these challenges. It offers cost-effective, immediate scaling options, as enterprises pay only for the hardware they need at each growth stage and avoid capital expenses. It also presents more processing power, efficiency, flexibility, and security than the traditional model.
How does IaaS work?
This model has a few essential components: virtual machines, operating systems, networking, and storage.
Virtual machines
IaaS utilizes virtual machines (VMs)—systems that provide virtual computing, networking, and storage resources that function just like their physical counterparts. VMs work thanks to virtualization technology and hypervisor software. They exist as multiple isolated, virtual server environments on a single physical server.
Operating Systems
IaaS provides the resources that operating systems (OS) need to function. This model works with whichever system an enterprise chooses, manages, and customizes—from Linux-based Ubuntu or Windows 11 Enterprise to a custom OS.
Networking
IaaS also leverages virtual networks (vNETs)—software-based frameworks that mirror the functions of physical networks without physical infrastructure. They interconnect applications, VMs, and users by enabling communication across locations. IaaS makes these networking resources available through the Internet or virtual private networks (VPNs), which are encrypted and more secure.
Storage
Three primary storage options are available through IaaS: block, file, and object.
Block storage operates like a hard drive and stores data as unique, distinct blocks. Its use cases include large-scale databases and enterprise-level applications. File storage stores data as files on a shared server, allowing for multiple-user access. It’s great for digital media and data within collaborative frameworks. Object storage separates data into isolated “objects.” Enterprises use it for IoT applications, content delivery, and unstructured data backups.
What are the benefits of IaaS for multi-location enterprises?
The four main benefits of IaaS for global organizations are cost-effectiveness, scalability, efficiency, and security.
1. Cost savings
With IaaS, there’s no need for upfront hardware expenditure. It also lowers monthly IT overhead by passing operational power, cooling, and maintenance costs off to service providers. The pay-as-you-go pricing model further optimizes savings, as every dollar spent has a purpose.
2. Scalability and flexibility
IaaS also lets you pay as you grow with seamless resource-scaling options, helping you adapt effortlessly in real time as your business needs change.
Adding new workloads and more advanced applications? Expand and diversify your integrations with ease. Testing new software? Rapidly build a robust developer environment. Experiencing demand spikes? Instantly augment your network resources.
3. More efficiency
IaaS increases efficiency with scaling capabilities, high-performance services, and low-latency solutions.
This model lets you deploy applications more quickly while maintaining availability throughout changes, helping you beat competitors to market. It optimizes resource usage, streamlines workflows, and reduces IT management overhead.
4. Enhanced security
Because IaaS providers manage infrastructural security, you’ll gain access to advanced security systems while maintaining complete control over your data and applications. High-quality vendors offer state-of-the-art security tools, world-class tech and monitoring services, and top-notch compliance.
Common IaaS use cases for global enterprises
Application hosting
This model’s scalability, security, and consistent availability make it easy to deploy and manage high-performance web applications in the cloud.
Data storage and backup
IaaS is ideal for securely storing critical data and cultivating redundancy across your network because providers supply varied storage solutions, diverse backup solutions, and powerful infrastructure capable of handling large, complex datasets. Vendors also offer storage integrations and data analytics.
Development and testing
Because IaaS offers high processing power and rapid scaling capabilities, developing and testing applications on the cloud is efficient and seamless.
Disaster recovery
As this model is cloud-based and secure, enterprises quickly access multiple backups and diverse recovery solutions through a centralized IT management environment.
High-performance computing
IaaS lets enterprises access robust infrastructure and advanced systems that they can’t build on-site. The cloud technology enables high-performance computing activities like simulation, advanced data analysis, and scientific automation.
Choosing the right IaaS provider
Consider the following factors when searching for a third-party partner:
Global reach and availability zones
Seek a widespread, well-distributed presence and a diverse network of availability zones.
Performance and reliability
Look into performance specs like latency, downtime, and overall efficiency. Prioritize providers that reliably maintain availability and rapidly enact disaster recovery protocols.
Security and compliance certifications
Ensure any potential partner offers advanced security monitoring, encryption, and access controls. Prioritize compliance certifications relevant to your industry.
Pricing models and cost optimization
Look for transparent pricing and customizable pay-as-you-go models you can use to optimize your costs.
Support and service level agreements (SLAs)
Only consider vendors that offer clear-cut, robust SLAs outlining ongoing cross-channel support with rapid response times and specific guarantees.
