Understanding IaaS
Infrastructure as a Service (IaaS) is a cloud computing model that allows businesses to rent resources as and when they need them. Users benefit from flexible access to virtual servers, networks, storage and other infrastructure components without the need for their organisations to manage related hardware. This allows them to focus on their core business and eliminates the impact caused by maintenance.
PaaS vs SaaS
It is important to understand the differences between Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). While IaaS is about provisioning essential infrastructure, PaaS offers a fully-fledged development platform complete with tools and deployment environments. SaaS, on the other hand, provides ready-to-use software applications that can be accessed from the cloud. Compared to both of these models, IaaS ensures greater flexibility and control over the underlying infrastructure.
The benefits of IaaS
Compared to other cloud computing models, IaaS offers several advantages.
Optimised scalability and flexibility. IaaS allows you to easily scale your resources to suit your ever-changing needs. All it takes is a few clicks to add or remove storage capacities, network resources and virtual servers for unparalleled agility.
Cost savings. Businesses can leverage IaaS to minimise their infrastructure overheads. Instead of spending money on expensive servers and never-ending maintenance, you only pay for the resources you actually use. Another benefit is a lower TCO as the IaaS provider takes on infrastructure management.
Access to high-performance IT resources. IaaS providers offer the latest resources to ensure high performance and guaranteed availability. Make the most of powerful servers, fast networks and high-performance storage solutions without having to buy or maintain any of it.
Simplified infrastructure management and operations. Leveraging IaaS means you don’t need to worry about physically managing your infrastructure as the provider takes care of maintenance, updates, security and backups so you can focus on your core business and save time and resources.
Companies of all shapes and sizes can leverage IaaS in a whole host of ways such as:
Application development and deployment. IaaS gives developers easy access to scalable resources to create, test and roll out applications. They can also quickly deploy development environments to shorten time to market.
Website and blog hosting. IaaS is a reliable and scalable hosting solution for websites and blogs that allows you to easily adjust resources to match traffic and therefore ensure optimum availability and the best user experience.
Test and development environments. Create flexible test and development environments with IaaS. Quickly deploy resources for load and compatibility tests or experimental developments without having to invest in extra hardware.
Data backup and recovery. IaaS is a reliable way of backing up and recovering data. Save your data backups in the cloud to make sure they are accessible whenever you need them.
