Perfect for businesses that want to scale virtual servers and storage in the cloud. Cloud Infrastructure as a Service (IaaS) allows businesses to buy and scale the computing resources they need by the minute, hourly or monthly. IaaS supports all of your website applications, databases, and storage needs.
What is Cloud IaaS?
Infrastructure as a Service (IaaS) is a category of cloud computing that provides virtualized computing resources over the Internet. It is one of three main categories of the cloud, alongside Software as a Service (SaaS) and Platform as a Service (PaaS).
With the IaaS model, a cloud provider hosts the hardware, software, servers, storage and other infrastructure components on behalf of its users. Cloud IaaS platforms offer highly scalable resources that can be adjusted on-demand. This makes IaaS well-suited for workloads that are temporary, experimental or change unexpectedly. Other characteristics of IaaS environments include the automation of administrative tasks, dynamic scaling, desktop virtualization, and policy-based services. IaaS customers pay on a per-use basis, typically by the minute, hour, week or month. Some cloud providers charge clients based on the amount of computing power or virtual machine space they use. This pay-as-you-go model eliminates the capital expense of deploying in-house hardware and software. However, users should monitor their IaaS environments closely to avoid being overcharged for unauthorized services.
Because IaaS providers own the infrastructure, systems management and monitoring may become more difficult for users. Also, if an IaaS provider experiences downtime, users’ workloads may be affected.
Why Select Cloud IaaS?
It’s a simple fact the cloud is the future. Each day, more CIOs and IT departments are moving away from colocation, dedicated servers, virtual private servers (VPS), and web hosting to embrace all that the cloud has to offer.
Cloud IaaS empowers businesses to create new websites and applications on the fly in dev environments and also launch in production in a matter of minutes. It provides computing resources on the fly and allows businesses to scale those resource up or down based on their present requirements.
Benefits of Cloud IaaS?
- Cost Savings: Increases savings by reducing underutilized capacity. It allows you to pay only for the capacity you need when you need it. IaaS helps organizations avoid the costs associated with ensuring uptime, maintaining hardware, and networking equipment or replacing old equipment.
- Flexibility: Provides added flexibility to scale infrastructure up or down on demand. IaaS serves as a great platform for all environments including development and testing.
- No Hardware: It reduces the need for costly hardware and technology refreshes. It shifts spending from a capital expenditure (CapEx) to operating expenditure (OpEx) and allows organizations to spend capital on their business.
- No Single Point of Failure: Most cloud providers offer replication and redundancy. If one server fails the service would be unaffected as there would be a remaining hardware resources and redundant configurations.
- Not Location Dependent: In the event of a natural disaster or a power outage at your company, keeping servers housed there can be very problematic if they are suddenly unavailable to customers. laaS allows businesses to house their data elsewhere where it wouldn’t be affected if something happened where the business was located.
