These are the servers, the network, virtualisation software, and hardware and software components that support a cloud-computing model. It also includes the abstraction layer whose job is to virtualise resources and present them logically to the users through an API -enabled command line and other application program interfaces. A service provider hosts these virtualised resources, which include components, virtual machines, servers, memory, and firewalls.
Components of cloud infrastructure
Cloud infrastructure is the back-end components and other elements that are found within most data centers. These are things like persistent storage, LAN equipment, and multi-core servers. Major cloud providers like Google cloud provide these services on multi-tenant servers. The model encompasses a huge capacity that can handle unpredictable changes in user demands. Thus, cloud infrastructure involves high-density systems, which have shared power. Unlike the traditional data centers, cloud infrastructure utilises attached storage in HDDs and SSDs.
Cloud infrastructure as a service
It’s now clear that cloud computing is composed of the hardware and software components. Infrastructure as a service (IaaS) on the other hand is a system that allows organizations to rent the IT infrastructure components from a cloud provider. This service model is referred to as IaaS.
With IaaS, you will not have to spend on on-premises infrastructure which is often expensive. Instead, there is a usage-based consumption model so that you only pay for what you have consumed. IaaS services are usually priced on a metered basis and to sustain usage, vendors provide discounts and provide prepaid options so that you enjoy the service with a guaranteed level of capacity in the agreed period.
Benefits of cloud infrastructure
Moving to IaaS lowers infrastructure costs; with this arrangement, it’s not your responsibility, to ensure uptime, maintain hardware, software, and other networking equipment. In case of business spikes, you don’t have to be worried because the arrangement allows for such adjustments without any extra cost.
Here, you only need to pay a fixed amount that would cover the agreed period. IaaS Cloud infrastructure services are metered and therefore on Pay-as-you-go basis. That means you only spend for what you need and no waste. In addition, you will not need to pay for those fixed large I.T bills.
Flexibility and scalability
Enterprise’s demands keep varying depending on the needs of the company. Thus, IaaS has the ability to scale up and down in response to such requirements. The providers usually have the most powerful and latest servers and technology to accommodate customer needs. The on-demand scalability is perfect in responding to changing requirements and opportunities. When your company wants to build or dismantle test and development environments, it would benefit a lot from the increased speed and agility.
Easy penetration to the market
In every industry, competition is strong and therefore, you must have a system that can help you penetrate the market easily. IaaS provides elasticity and scalability and therefore you can rump up and get your product to the market as fast as possible.
Today, you don’t have to spend money, time and energy on installing infrastructure and hiring staff to manage your IT systems. That time can be spent on attending to other matters that are core to the business.
