Understanding Infrastructure-as-a-Service (IaaS): Here’s What Businesses Need to Know
When major leaps in virtualization and various other technologies started to converge into what now known as “cloud computing”, the IT world underwent a seismic shift, which gave birth to a powerful force known as Infrastructure-as-a-Service (IaaS). Today, it is one of the three main categories of cloud computing, alongside SaaS and PaaS. IaaS is a form of cloud computing which provides virtualized computing resources (such as processing power, servers, storage space, security, OS licensing, and network connectivity) over the internet.
Here are some of the most featured advantages of IaaS:
- Eliminates capital expense and reduces ongoing cost;
- Improves business continuity and disaster recovery;
- Responds quickly to shifting business conditions;
- Helps you focus on your core business goals;
- Increases stability, reliability, and support ability;
- Provides better security for your applications and data;
- Assists you in delivering new apps to your users faster.
One of the key factors that differentiate it from other forms of cloud computing is that it enables you to create your own cloud platforms and applications. The most common uses of IaaS include delivering applications, storing data, hosting websites on virtual servers, and creating virtual data centers.
Let’s talk about IaaS in detail, including what it is, what it can do for your organization, and what it has in store for you in 2018.
What exactly is IaaS?
Gartner describes Infrastructure-as-a-Service (IaaS) as a “standardized, highly automated offering, where compute resources including storage and network capabilities are owned by a service provider and offered to the consumer on demand.”It comprises hardware and software components that give IT professionals an additional control over their cloud environment.
Let’s dig deeper!
- IaaS takes the physical deployment and on-site maintenance tasks out of IT infrastructure as it uses vendors’ servers instead of on-premises servers.
- While most IaaS deployments utilize servers that are hosted off-site (outside the organization), enterprises still have the option of deploying their IaaS cloud on-premises.
- Some of the key characteristics of IaaS include automated administrative tasks, dynamic scaling, platform virtualization, and internet connectivity.
- Unlike SaaS and PaaS, an Infrastructure-as-a-Service model gives organizations more control over the cloud environment rather than vendors by allowing them to implement applications, data, runtime, middleware, and OS.
- IaaS allows organizations to access their user interfaces (UIs) and application programming interfaces (APIs), thus giving IT admins the authority to modify the way applications manage and store data.
How can organizations benefit from IaaS?
Businesses these days are leveraging IaaS to get up and running in a matter of hours without spending hefty capital expenditure. One of the major reasons why companies are so eager to adopt Infrastructure-as-a-Service is the way it cuts costs.
Since it’s an online process, business owners don’t have to spend their valuable time and hard earned money on investing in hardware for their own infrastructure; all of this is well taken care of by the IaaS vendor the company appoints. This certainly means that there’s no need for companies to worry about maintenance and replacing old and outdated equipment.
Furthermore, since most the technical tasks are being carried out by the vendor, minimal on-site staff would be required. Another key advantage that IaaS brings to the table is its pay-as-you-go mode of payment, which allows companies to pay only for the services they use.
Some of the most prolifictasks organizations perform with IaaS include:
- Test and development;
- Website hosting;
- Storage, backup, and recovery;
- Web app support;
- High-performance computing;
- Big data analysis.
Three of the most common examples of IaaS are Amazon Web Services (AWS), Microsoft Azure service, and Google Compute. There are many other companies competing in the race but none of them are even close to the top three. Thanks to its robust, agile, and inexpensive outsourced infrastructure, IaaS is now utilized by businesses of all sizes such as finance, retail, media, and telecommunications.
According to experts and recent studies, IaaS is the perfect solution for organizations that are:
- Confronting the expense of a technology or hardware refresh;
- Prepared to implement EHR solutions which require convoluted environments;
- Understaffed as a result of changing needs or loss of proficient and experienced IT professionals;
- Desiring a disaster recovery environment;
- Worried about ePHI security or other compliance issues (concerning HIPAA compliant providers);
- In search of a more predictable and secure cost structure.
What to expect from IaaS in 2018
IaaS has proven to be one of the most popular branches of cloud computing and is forecasted to grow at a much faster rate in 2018 and beyond. Forrester predicts that 2018 will be the year of Infrastructure-as-a-Service (IaaS). The IaaS market – which comprises an array of cloud-based services that not only provide data and insights to clients but also help them leverage that data into action – is expected to grow to 3.33 billion by 2021, according to Gartner.
Fascinating, isn’t it? Well, that’s not it!
As per a study by Statista, the Infrastructure-as-a-Service market is predicted to reach $17.5 billion worldwide in 2018. Taking these numbers into account, it can be stated that IaaS does have a bright future ahead of it. On the whole, adopting Infrastructure-as-a-Service (IaaS) for your business could dramatically reduce costs, increase customer lifetime value, and help you achieve or grow profitability.
