Infrastructure as a Service (IaaS) is an instant computing infrastructure that is provisioned and managed over the Internet. With Layer 7 Data Solutions, quickly scale up and down with demand, and pay only for what you use. IaaS helps you avoid the expense and complexity of buying and managing your own physical servers and other datacenter infrastructure. Each resource is offered as a separate service component, and you only need to rent a particular component for as long as you need it.


Lack of resources/expertise in the cloud increased from 27 percent in 2015 to 32 percent in 2016 to supplant security as the largest concern. As more organizations are placing more workloads in the cloud, the need for expertise has grown. Additional training of IT and development staff will be critical to helping address this challenge.

Common IaaS Business Scenarios

Typical ways SMBs and enterprises utilize IaaS include:


Test and development: Teams can quickly set up and dismantle test and development environments, bringing new applications to market faster. IaaS makes it quick and economical to scale dev-test environments up and down.

Website hosting: Running websites using IaaS can be less expensive than traditional web hosting.

Storage, backup, and recovery: Organizations avoid the capital outlay for storage and the complexity of storage management, which typically requires a skilled staff to manage data and meet legal and compliance requirements. IaaS is useful for handling unpredictable demand and steadily growing storage needs. It can also simplify the planning and management of backup and recovery systems.

Web apps: IaaS provides all the infrastructure needed to support web apps, including storage, web and application servers, and networking resources. Organizations can quickly deploy web apps on IaaS and easily scale infrastructure up and down when demand for the apps is unpredictable.

High-performance computing: High-performance computing (HPC) on supercomputers, computer grids, or computer clusters helps solve complex problems involving millions of variables or calculations. Examples include earthquake and protein folding simulations, climate and weather predictions, financial modeling, and evaluating product designs.

Big data analysis: Big data is a popular term for massive data sets that contain potentially valuable patterns, trends, and associations. Mining data sets to locate or tease out these hidden patterns requires a huge amount of processing power, which IaaS economically provides.


Advantages of IaaS

Eliminates capital expense and reduces ongoing costs: IaaS sidesteps the upfront expense of setting up and managing an onsite data center, making it an economical option for startups and businesses testing new ideas.

Improves business continuity and disaster recovery: Achieving high availability, business continuity, and disaster recovery is expensive since it requires a significant amount of technology and staff. But with the right service level agreement (SLA) in place, IaaS can reduce this cost and access applications and data as usual during a disaster or outage.

Innovate rapidly: As soon as you’ve decided to launch a new product or initiative, the necessary computing infrastructure can be ready in minutes or hours rather than the days or weeks—and sometimes months—it could take to set up internally.

Respond more quickly to shifting business conditions: IaaS enables you to quickly scale up resources to accommodate spikes in demand for your application—during the holidays for example—then scale resources back down again when activity decreases, to save money.

Focus on your core business: IaaS frees up your team to focus on your organization’s core business rather than on IT infrastructure.

Increase stability, reliability, and supportability: With IaaS, there’s no need to maintain and upgrade software and hardware or troubleshoot equipment problems. With the appropriate agreement in place, the service provider ensures that your infrastructure is reliable and meets SLAs.

Better security: With the appropriate service agreement, a cloud service provider can provide security for your applications and data that may be better than what you can attain in house.

Gets new apps to users faster: Because you don’t need to first setup the infrastructure before you can develop and deliver apps, you can get them to users faster with IaaS.
