An Essential Comparison Between IaaS, PaaS, and SaaS
Cloud computing is now widely adopted by small enterprises and global businesses. With different service models depending upon types of computing, you need to know the differences and select one that caters to your niche. Before getting into the differences between these cloud models, here is a look at some of the overall benefits cloud services bring to enterprises, regardless of the industry they belong to.
- Cost Savings
- Security
- Flexibility
- Increased Collaboration
- Disaster Recovery
- Loss Prevention
- Automatic Updates
Now, here are the three fundamental service categories of the cloud.
Infrastructure as a Service (IaaS)
IaaS primarily caters to companies requiring infrastructure on-demand. It includes a highly-scalable and automated compute software. In IaaS, vendors provide customers with pay-as-you-go access to resources like storage, networking, and more through the cloud. Therefore, the cost for it varies and is reliant on consumption. Fluctuating workloads are accommodated here because the infrastructure is scalable. IaaS can be utilized for data centers and to build a virtual server environment, website or application hosting, and large-scale data analysis. Furthermore, companies can save more time for work by making administrative tasks virtualized.
Platform as a Service (PaaS)
PaaS makes certain cloud components available for developers to build applications as per their requirements. Essentially, the framework is given through the web upon which customized applications can be made. The computing resources are managed either by a third-party or the merchandiser, and application management is handled by the developers. Overall, PaaS is simple and facilitates multiple tasks to build, test, and host applications through a single environment.
Software as a Service (SaaS)
Also known as cloud application services, SaaS it is the most popular among online retailers allowing them to deliver applications managed by third-party merchants to users. Many of these applications can be run directly through your web browser and therefore do not require any download or installation.
The global cloud services market is on a path of rapid growth, accelerated partly by the Covid-19 pandemic and increasing remote operations policies. The overall market projection for cloud services in 2021 is about $306.9 billion. SaaS is a leading player in this market with a forecast of $120.9 billion. IaaS and PaaS follow closely with projections of $64.3 billion and $57.3 billion, respectively.
Depending on the size of your business and the nature of operations, you can make use of one or more cloud service models.
