IaaS, PaaS, SaaS: What We Need to Know, Examples & More
If you are considering moving your E-Commerce business to the cloud, here are are the three crucial acronyms to wrap your head around:
- IaaS
- PaaS
- SaaS
These are the three main types of cloud computing. You may have heard them before experiencing a wave in popularity by shifting more E-commerce business to the cloud.
- SaaS is estimated for approximately 24 % of all enterprise workloads.
- IaaS is floating around 12%.
- PaaS is currently the most common model approaching about 32% and is expected to grow in the coming time.
Key Difference Between on-Premise, SaaS, PaaS, IaaS
All of the IT company’s systems were on-premise, and clouds were quite white fluffy things in the sky. SaaS, PaaS, and IaaS are simply three ways of describing how we can use the cloud for our business.
- IaaS: cloud-based services, pay as we go for services such as storage, networking, and virtualization.
- PaaS: hardware and software tools obtainable over the internet.
- SaaS: software that’s possible via a third party over the internet.
- On-premise: software installed in the same building as our business.
Examples of IaaS, PaaS, SaaS
Most companies use SaaS and IaaS Cloud computing models, while many developers use PaaS to build apps.
- SaaS Examples: Google Apps, Salesforce, MailChimp, ZenDesk, Slack, Hubspot, etc.
- PaaS Examples: AWS Elastic Beanstalk, Heroku, Windows Azure (used mostly for PaaS), Force.com, OpenShift, Apache Stratos, Magento Commerce Cloud.
- IaaS Examples: AWS EC2, Rackspace, GCE, Digital Ocean, Magento 1 Enterprise Edition.
Our team excels in PaaS application development, leveraging cutting-edge technologies to build scalable and efficient cloud-based solutions.
IaaS (Infrastructure as a service)
IaaS businesses offer assistance such as pay-as-you-go storage, networking, and virtualization. It provides users with a cloud-based alternative to on-premise infrastructure so companies could avoid investing in expensive on-site resources.
IaaS delivery:
Over the internet
IaaS advantages:
Managing on-premise support is costly and labor-intensive. It frequently requires a vital initial investment in physical hardware. We will then e need to engage external lighting contractors to maintain the hardware and keep everything working and up-to-date.
IaaS solutions are extremely flexible and highly scalable, and we can replace them whenever we need them without losing any money on our initial investments. Another advantage of IaaS is it sports authority over the infrastructure back in our hands. We are no longer required to place the face in an external IT contractor to access and oversee IaaS platforms ourselves if we wish.
IaaS characteristics:
IaaS platforms are:
- Extremely flexible and scalable
- Accessible by multiple users
- Cost-effective
When to use IaaS:
IaaS is profitable for businesses of all shapes and sizes. It allows total control over our infrastructure and works on a pay as you use the model to fit into most budgets. With most of these platforms, we can obtain access to ongoing support and have the option of scaling up our specifications at any time. Using IaaS is a great way for future-proofing our business.
PaaS (platform as a service)
PaaS vendor implements hardware and software tools over the internet, and people use them for developing applications. PaaS users tend to be developers.
PaaS delivery:
Over the internet
PaaS advantages:
PaaS is essentially used by developers who are trying to build software applications. It means that developers are not required to start from scratch when creating an application that saves them a lot of time and money on writing extensive coding.
PaaS is a very conventional choice for manufacturers who need to create unique applications without paying a fortune or catching on responsibility. It’s kind of like the distinction between hiring a venue to put on a show and creating a platform for putting on a show. The forum stays the same but what we want to make in that space is unique.
PaaS characteristics:
PaaS platforms are:
- Accessible by multiple users
- Scalable indicating that we can choose from different tiers of resources to suit the size of our business.
- Built on the technology of virtualization.
- Easy to execute without extensive system administration knowledge.
When to use PaaS:
PaaS is frequently the most cost-effective and time-effective method for a developer to design a unit application. It allows the developer to focus on the creative side of application development instead of menial tasks like managing software updates for security patches. All of their time and brainpower will go into designing, testing, and extending the app.
SaaS (software as a service)
SaaS platforms make software available to users all over the internet, usually for a monthly subscription fee.
SaaS delivery:
Over the internet.
SaaS advantages:
Using service, we are not required to install and run software applications on our computer system. Everything will be available on the internet when we log into our account online. We can normally obtain the software from any device anytime as long as we have an internet connection.
The same goes for anyone else using the software. All of our staff will be provided with personalized login suitable for the access levels. It is all taken care of in the cloud. Another key advantage is the payment structure.
Most of the subscriptions cover maintenance, components, and security services, which could be time-consuming and expensive when using on the software premise. SaaS model providers offer out of the box solutions that are simple for setting up if we require a basic package with more complex solutions for larger organizations.
We could have the necessary software up and running within a matter of hours, and we will have access to customer services and support along the way.
SaaS characteristics:
SaaS platforms are:
- Available all over the internet.
- Hosted by the remote server or by a third-party provider.
- Scalable with different tiers of small, medium, and Enterprise level business.
- Inclusive, offering security, components, and maintenance as a part of the cost.
When to use SaaS:
The SaaS model is perfect when we want an application to run smoothly and reliably with minimal input. We can take our email server, for example. We want to know that we will continue to send and receive emails without fiddling with our email settings, worrying about the updates.
Imagine if our email server went under because we forgot to update it, and we went days without email? That is not an option in today’s marketplace. If we use a SaaS platform for running our mailbox, the chances of something going wrong are very small, and if something did go wrong, it would be up to the service provider to find a solution.
For our clients seeking SaaS development services, our team delivers tailored solutions crafted to meet their unique business needs and drive growth.
Conclusion
IaaS, PaaS, SaaS growing prominence reduce the need for hosting on-site. These models offer users preference, consistency, and choices that can not be given on-site hosting. Such models are more complex than others in a cloud computing server. The system administration understanding level decreases as we go down the list in this order: On-premise > IaaS > PaaS > SaaS.
