Advantages of IaaS in cloud computing

Advantages of IaaS in cloud computing:

In this article, we discussed the top advantages of IaaS (Infrastructure as a Service) in cloud computing that are being used in the real world, but first of all, let’s discuss the definition of IaaS, what is provided by IaaS, and how it works.

Cloud-based services are undoubtedly the present and future of technology and computing infrastructure. Organizations of all sizes and across all industries are increasingly adopting and deploying cloud-based applications and services as part of their current IT infrastructure.

The reason for this shift is the emergence of solutions such as infrastructure as a service (IaaS) that provide rapid infrastructure. This allows businesses to focus on their core business without spending resources on specific aspects of IT management.

According to Gartner, IaaS is the fastest-growing area of ​​public cloud service delivery models, with total spending expected to double from $59 billion in 2020 to $106 billion in 2022.

Let’s take a look at the benefits of IaaS for your organization and why you need to empower your IaaS-based workloads with a robust cloud-based identity and access management (IAM) solution.

What is IaaS in cloud computing?

Infrastructure as a Service (IaaS) is a software delivery model in which a provider hosts the infrastructure needed to run a software application. This includes the operating system, network infrastructure, security services, and the software application itself.

This is a great option for startups that need a high level of control over their infrastructure but don’t have the time or expertise to build it on their own.

Similarly, large enterprises can leverage IaaS to build state-of-the-art infrastructure without worrying about the day-to-day operations of maintaining and updating the infrastructure.

IaaS is a cloud-based service that provides critical IT resources such as servers, networking, and storage on demand to customers through a “pay-as-you-go” pricing model. IaaS allows you to avoid the cost and complexity of purchasing and managing physical servers and an entire data center infrastructure.

Unlike the SaaS (software as a service) model, IaaS allows you to manage your applications, data, runtimes, and more. The service also provides the flexibility you need to scale up and down your IT resources based on your needs. For example, choosing IaaS allows you to quickly provision new workloads and increase the reliability of your underlying IT infrastructure without installing additional hardware.

What does IaaS provide?

IaaS provides a set of services that help business professionals organize their data and software usage. There are three main areas of computing that IaaS can contribute to. The first is server and storage management, which includes tasks such as setting up new servers and storing and sharing data among users. Another service area provided by IaaS is firewalls and security networks that can protect users and their data from cybersecurity breaches. IaaS also helps build data centers and physical plants where users can monitor computing performance.

How does IaaS work?

IaaS works by allowing users to access data and complete other computing tasks over the Internet in the cloud. In other words, IaaS allows you to engage in computing from almost anywhere without going near a physical computer server. IaaS also has the ability to automate certain computing tasks, such as processing power and data storage, making it easier for users. IaaS bundles services and allows users to choose which services to purchase and use, allowing them to manage all of their computing processes without investing in many resources. For example, a company can use an IaaS provider to host online applications that customers can use. Instead of building their own servers, businesses can store their applications on IaaS servers for a monthly fee, and users can access them online at any time.

What are the top 5 advantages of IaaS in cloud computing?

Now that you understand what IaaS is, let’s take a look at the five key benefits of using this type of cloud-based service in your organization.

1. Cost savings

The most significant benefit that businesses get from IaaS may be cost savings. With IaaS, you don’t have to spend money to ensure that your servers, storage, and networking equipment are in good working condition.

IaaS can also reduce costs because it shifts spending from a capital expenditure (CapEx) model to an operating expenditure (OpEx) model and provides a consumption-based approach to IT resources.

It is more cost-effective because you only pay for what you consume, rather than paying upfront for hardware that may become obsolete over time. For example, IaaS can be used to support an e-commerce website during peak times or to support testing and development cycles that last only a few weeks.

2. Flexible scalability

IaaS providers can’t predict the actual needs of their customers, so they design IT products that can adapt to the demands of specific workloads. So whether you’re dealing with small and medium-sized enterprises (SMEs) or large enterprises, IaaS can easily scale to meet the demands of your workload. This flexibility and scalability allows organizations to easily predict growth.

For example, if a company achieves its original goals and has room to expand its IT operations, IaaS can easily scale to accommodate these new needs. Additionally, if your organization’s traffic increases due to a successful marketing campaign, your IT team can immediately provision resources to handle the surge in visitors.

3. Faster time to market

Unless your product is really good or your marketing team is exceptionally talented, it is usually difficult to gain customer attention and market share over already popular competitor products. Therefore, time to market is critical. This allows you to target more customers before your competitors do.

IaaS can help accelerate time to market by significantly reducing upfront costs. Easily build IT infrastructure in hours via virtual machines (VMs) on a budget. There is no need to purchase expensive physical servers. Purchasing physical servers can result in delays of weeks or months due to cost and provisioning challenges.

4. Increased support, performance, and security

On-premises disaster recovery and business continuity planning can be costly and complex, especially if your company is distributed across multiple locations. IaaS allows organizations to easily access their infrastructure over the Internet from anywhere.

IaaS providers implement security measures such as multi-factor authentication (MFA) and strong encryption protocols that customers can leverage to protect their IT infrastructure. Most importantly, IaaS data centers have multiple network connections, power, and cooling systems to avoid interruptions in productivity.

5. Supports a business-growth mindset

Spending money, time and effort making decisions about sourcing, purchasing and maintaining IT equipment is not only tedious and complicated, but it can also distract an organization from its core strategic goals. By leveraging IaaS, organizations can spend more time innovating and growing their business rather than making technology decisions. 

Disadvantages of IaaS:

Security Risks

Cloud computing environments are not as secure as physical servers, making it easier for hackers to break into them. It is more secure if your system is on your local network. However, this advantage of a cloud computing environment also has disadvantages, such as a lack of control over resources.

Unexpected Cost

IaaS is typically cheaper than buying the same service in packaged form. However, the cost of using IaaS services can add up unexpectedly, making IaaS seem even more expensive than traditional services. For example, IaaS providers typically use a formula to calculate monthly bandwidth usage. As your usage increases, your bill may increase, even if you haven’t used more services.

Dependency on Third-Party Service Provider

IaaS is the best option for many organizations, but it also has its own challenges. One of the biggest challenges is provider dependency. In the case of Amazon Web Services (AWS), it owns the hardware and is therefore the sole provider of computing resources. When you use IaaS, in addition to paying for the operating system, software applications, and data storage, you also pay for computing resources.

Technical Problems

IaaS technical problems arise due to the lack of standardization in the cloud environment. Cloud service providers have not yet standardized the following aspects of the cloud environment, including networking, service models, security, and network architecture.
