Infrastructure as a service

What is infrastructure as a service (IaaS)?

Infrastructure as a service, or IaaS, is a type of cloud computing that provides the entire infrastructure needed to run a business. That includes everything from computing power, network, on-demand storage, and everything that runs on online servers.

IaaS is an excellent choice for companies looking to scale up their operations and boost performance without investing in on-premises systems and traditional data centers. As an IaaS user, you will get everything you need, including the most advanced software with state-of-the-art security features.

How does infrastructure as a service work?

Infrastructure as a service is designed to simplify the complexity of storage management from a single online cloud. It involves all kinds of advanced automation designed to help with infrastructure management responsibilities, management of backup files, physical servers, and file location, allowing you to meet your business requirements with ease.

Since it runs on virtual machines, you won’t have to invest in new physical servers or similar pricy hardware. Moreover, all your team members will be able to access the dashboard from a remote server the same way they would access legacy infrastructure servers.

That will allow your company to achieve business continuity and improve the overall business logic without expanding existing systems. You will be able to access every log file on every device, including virtual machines and physical machines.

Who would use IaaS?

The idea behind IaaS is to provide businesses with the computing resources they need on-demand. You can use it in many different ways, but it’s most popular among companies looking to bring their developed environments to a new level.

IaaS can work with existing systems, as well as a private cloud. It simplifies many processes, helps bring apps to users, and assists with coping with bigger workloads.

Advantages of IaaS?

When compared to the needs of a legacy infrastructure system, IaaS is much easier to manage. It provides several real benefits that allow companies to address more inquiries and handle more data from a single online solution. Here are some of the main benefits IaaS provides:

Automatic updates and disaster recovery

Cloud computing offers better security features and allows all apps and data pipelines to keep running during a power outage. Automatic updates keep the system in perfect working condition at all times.

Faster scaling

IaaS is the ideal choice for growing companies as it allows quick scaling of resources according to demand.

Focus on growing

Instead of worrying about investing in IT infrastructure, physical hardware, and computing power, companies can focus on other business activities.

Implementation of infrastructure as a service

One of the best features of IaaS is that it can work with any system, including public, private, and hybrid cloud settings. Users can set everything up from a single dashboard without investing in new computing and internal resources.

With cost management in mind, IaaS can help businesses optimize their compute resources, boost workloads, and grow their operations on-demand.

A pricing cost calculator will help you find the best IaaS for your needs. You can upgrade all networking capabilities at any time with zero IT costs.

Examples of infrastructure as a service

Companies can use IaaS for many different purposes, but here are some of the use cases where it helps tremendously:

  • A/B testing and development flexibility;
  • website hosting;
  • data storage, backup, and recovery;
  • web applications;
  • HPC level computing;
  • data warehousing and big data analysis.

Most known examples of Iaas include Amazon Web Services, Google Cloud Engine, and IBM Cloud.


What resources are provided by infrastructure as a service?

IaaS provides the complete infrastructure needed to run a business online. That includes everything from computing power, virtual servers, data storage, improved security, load balancing, network devices, and everything in between.

What is an Infrastructure layer?

The infrastructure layer manages the system-to-system interactions. It receives, stores, and provides data upon request. This can be required by your top-level application or other additional software you might want to integrate into your system.

A good example of a third-party provider integration is LiveAgent help desk software which you can connect to your IaaS infrastructure layer using API. It allows you to communicate with LiveAgent or any other integrated application with an added layer of security and ease.

Do IaaS platforms integrate with PaaS platforms or SaaS software?

They most certainly do. IaaS simplifies management in any environment, including PaaS and SaaS. Adding IaaS to existing solutions can help users improve efficiency and operation for everyone involved. However, be aware that integration with some SaaS solutions may not be possible.

Disadvantages of IaaS

Cloud computing is changing the IT industry forever. It provides many significant benefits, but it comes with a few drawbacks as well. Here are some of the disadvantages of using an IaaS:

  • not having complete control over cloud security
  • it doesn’t work with all existing software
  • you might experience some downtime during implementation
  • the IaaS provider has full control of your data
  • no control over updates or maintenance

Video summary

The video discusses what IaaS means in cloud computing, which stands for Infrastructure as a Service. It's the infrastructure part of cloud and is broken down into three main categories: compute, storage, and network. Compute is where the processing and computing gets done and falls into three categories: general purpose computing, graphics processor for machine learning and AI, and high-performance computing. Storage has three main types: object storage (for general purpose storage), block storage (for specific applications that require its features), and file storage. Network is the pipe that ties everything together and has two main components: size (measured in megabits or gigabits per second) and bandwidth (measured in amount of data pushed through over a set period of time). As-a-Service offerings are generally shared, billed hourly/monthly, have no contracts, and are self-service. There are different kinds of as-a-Service offerings, with IaaS being specifically about infrastructure.

Do you know the difference between the help desk vs service desk? Find out the definition of each and learn why they are not the same.

Help desk vs Service desk

A service desk is a management component of an organization's IT support capabilities, while a help desk is a component of the service desk that focuses on end-user services. While help desks are user-centric and reactive in nature, service desks are business-centric and proactive in ensuring smooth IT operations. A company's choice between the two depends on their specific needs and goals. The right customer service tool, whether it's a help desk or a service desk, should be flexible enough to adapt to specific business requirements and provide high-quality service.

Get to know more about platform as a service - PaaS. Understand in depth with explanations from professionals.

Platform as a Service (PaaS)

Platform as a Service (PaaS) is a cloud computing model that enables developers to create, maintain, and deliver applications using premade programming tools and application infrastructure components provided by a cloud service provider. PaaS comes with underlying infrastructure, networking, storage, and servers, allowing developers to create various types of applications like middleware, database management, software deployment, and intelligence services. PaaS is superior to internally hosted development environments as it provides internal resources, network resources, and complete control over the development process with the initial investment. PaaS solutions include AWS Elastic Beanstalk, IBM Cloud, and Google App Engine.
