Infrastructure as a service (IaaS) sometimes in general termed as Cloud Infrastructure is an instant computer structure, provided and managed via the Internet. It is one of four types of cloud services, along with software as a service (SaaS), platform as a service (PaaS) and a server.
IaaS quickly scales up and down with demand and only allows you to pay for what you use. It helps you avoid the hassle and hassle of purchasing and managing your own physical servers and other data center infrastructure. Each resource is available as a separate service component and only specific service component to be billed for as long as you need it. Cloud computing services, such as AWS, Azure, manage the infrastructure while you purchase, install, configure, and manage your own software – operating systems, middleware, and applications.
Advantage of IaaS
Reduces capital costs and reduces ongoing costs. IaaS avoids the cost of setting up and managing an on-site data center in advance, making it a viable option for start-ups and companies testing new ideas.
Improves continuous trading and recovery from disasters. Achieving high supply, business continuity and disaster recovery is expensive, as it requires significant technology and staff. But having right service level agreement (SLA) in place, IaaS can reduce these costs and gain access to applications and data as usual in the event of a disaster or failure.
Fast Innovations. Once you have decided to launch a new product or initiative, the necessary computer infrastructure can be ready in minutes or hours, rather than days or weeks – and sometimes months – it may take to set up indoors.
Respond faster to changing business conditions. IaaS allows you to expand resources quickly to meet peaks in demand for your application – for example over the holidays – then shrink resources back down as activity decreases to save money.
Focus on your core business. IaaS frees your team to focus on the core business of your organization rather than information technology.
Increase stability, reliability and support capacity. With IaaS, there is no need to maintain and update software and hardware or solve equipment problems. having right agreement in place, the service provider ensures that your infrastructure is reliable and SLA compliant.
Better security. Having right service agreement, a cloud service provider can provide security for your applications and data that can be better than what you can achieve in-house.
Gets new applications to users faster. As you don’t have to install infrastructure first before you can develop and deliver applications, you can get them to users faster with IaaS.
