These days, companies in all sectors utilize cloud computing, as it can bring many benefits. If you’re considering moving your business to the cloud, whether by yourself or with the help of a third-party provider, it’s very important to understand the differences and advantages of the various cloud services.
The main types of cloud computing that are available are Platform as a Service (PaaS), Software as a Service (SaaS), and Infrastructure as a Service (IaaS).
What is Platform as a Service (PaaS)?
Platform as a Service (PaaS) provides cloud components to certain software while being used for creating applications. PaaS offers a framework for developers to build upon and use to create custom applications. All storage and servers can be managed by the company or a service provider, while developers maintain application management.
Advantages of PaaS
- Lower Costs – A lot of expenses, such as costly server space and IT manpower, are reduced by PaaS solutions, as you don’t need to build applications from scratch. If you have limited resources or want to reduce your operating costs, PaaS is a good option.
- Reduced Coding Time – PaaS provides pre-coded application components, such as libraries, frameworks, and templates, that are already incorporated into the platform. This helps speed up and simplify the development process.
- Quicker Launch, Testing, and Development – Prebuilt backend infrastructure enables faster prototyping and development. This way, you can release applications quicker, which can increase your chances of success. PaaS offers access to different machines and configurations for testing, which allows you to make changes to the app in a shorter time.
- Easier Maintenance – PaaS providers are responsible for building, updating, and configuring servers, which frees developers from those tasks.
- Quicker Sharing of Data in Teams – PaaS usually allows the sharing of data among many development teams, so your company doesn’t have to allocate the same resources to different teams.
- Data Integration and Aggregation – Creating applications includes data integration and aggregation over time. PaaS provides the necessary components, which speeds up development work.
What is Software as a Service (SaaS)?
Software as a Service (SaaS) is the most utilized option for organizations in the cloud market. SaaS uses the internet to deliver ready software products that are managed by a third-party provider, to its users. Most SaaS applications don’t require downloads or installations from the client, as they’re run directly through their web browser.
Advantages of SaaS
- Simple to Implement and Use – SaaS model is very simple to put into practice, as all you need is a web browser and an internet connection. SaaS is also accessible on various devices and from anywhere in the world.
- Scalability – SaaS providers usually offer numerous subscription options and the freedom to switch subscriptions if it’s necessary, for example, when your business expands, and more users are required to access the service.
- Cost Reduction – SaaS providers are responsible for resolving potential technical issues, and they handle data, servers, and storage networking. They also provide compliance, maintenance, and security services to their users. All of this can significantly cut your costs.
- Time-Saving – There is no need to download and install applications on individual devices, so the technical staff is free from tasks related to installing and upgrading the software.
- Stable Delivery – SaaS providers secure the stable work of their SaaS solutions as much as possible, which means your business will work with minimal downtime.
- Data Backup – SaaS includes backup software delivered through the cloud that helps store and protect data created with a SaaS product. This way, your company can save on backup and storage of its data.
What is Infrastructure as a Service (IaaS)?
Infrastructure as a Service (IaaS) consists of highly scalable and automated compute resources. IaaS is entirely self-service for computer access and monitoring, networking, data storage, and other services. It allows organizations to purchase resources when needed instead of buying hardware outright.
Advantages of IaaS
- Reliability – Technical issues, such as failure of a hardware component, won’t affect your infrastructure. IaaS providers also distribute the system’s workload across multiple data centers and servers, which makes the hardware, computing resources, and cloud-based apps always available.
- Operational Flexibility – IaaS allows your team to access the hardware, applications, and computing power used regularly. This way, they can view the required data and files on the go anytime.
- Scalability – IaaS cloud model can be scaled quickly according to the growing business needs of your organization. IaaS providers offer very powerful networking technology and storage to meet the requirements of their users.
- Economical – IaaS eliminates the need for infrastructure, therefore it’s the most cost-effective alternative for businesses.
- Disaster Recovery and Business Continuity – If an organization has several branches, each of them needs separate disaster recovery and business continuity plans. IaaS combines those plans, and if a disaster happens, a company can rely on them. This reduces costs and saves business manageability.
- Concentration on business expansion – Since third-party providers maintain the infrastructure, you can concentrate on other tasks that are more crucial for your business’s growth and development.
What is the best choice – PaaS, SaaS, or IaaS?
These cloud service models provide different features and functionalities, so the answer depends on your business and its specific characteristics.
PaaS would be the most suitable option if you need a platform designed for developing software products.
SaaS would be the best choice if you want out-of-the-box features and no hassle of installation.
IaaS can help your business if you need highly flexible and scalable service while maintaining control of its infrastructure.
