Cloud computing is deemed an emerging technology that is transforming business operations by accelerating software development. Organizations that consider using cloud computing services often face a difficult choice between PaaS, IaaS and SaaS.
Are you looking to leverage PaaS, IaaS, and SaaS cloud models? In this blog, we will break down the understanding of these three models and how they can positively influence your operational efficiency.
PaaS (Platform as a Service) is managed by a cloud service provider where organizations can run, deploy, and manage software. This cloud platform includes backend infrastructure, operating systems, networks, databases, servers, and runtime environments, which are needed to deploy and test applications. It is deemed a good choice for developers as their attention is solely on the development of applications rather than focusing on the underlying infrastructure. Being an open-source cloud platform, it provides a seamless shift from one provider to another.
PaaS is a simple and convenient cloud solution with some great features that you must check out.
Application Hosting: It ensures that applications are hosted without requiring direct management or hardware. PaaS will simplify the building of applications and configuration of infrastructure, making them accessible and performant as per your needs.
Middleware Capabilities: PaaS comes with middleware capabilities to allow seamless communication between applications and databases. Developers can reduce the amount of code by using built-in systems and libraries.
Development Framework: Even complex systems can be simplified with the PaaS development framework. The code libraries, integrated development environment, and database management systems create a path for quick application development.
The users of PaaS are privileged with a cloud platform that allows them to run, test, deploy, and build an app, which might not be possible when using an on-premise solution. Here are some primary benefits of PaaS for businesses:
Fast Development for Faster Time to Market
PaaS offers pre-built components and frameworks, which create a hosting environment, accelerating application development. Your entire production cycle takes within minutes, allowing your business to have a fast time to market.
A Scalable Approach
The components of PaaS are designed to be scaled up or down according to business requirements. This cloud solution is perfect for running an application for a short period. It can ensure optimal performance through staging and running applications whenever needed.
No Management Required
A third-party cloud service provider manages your infrastructure, patch management, and other related tasks. You do not have to worry about software security updates, as the vendor ensures the automatic upgrade of the application with the latest features and security enhancements.
Cost-Efficiency
PaaS will eliminate the purchase of heavy physical equipment for application development, as it is expensive and often difficult to install. This cloud model can be treated as a cost-effective option to host applications in a safe environment. With a pay-as-you-go model, it offers the scalability and flexibility that your business needs.
Simplified Collaboration
Since PaaS is a cloud-based solution, it provides a shared development environment that encourages managers, teams, and stakeholders to collaborate efficiently. Everyone will get shared access to development tools, which can be possible anywhere with an Internet connection.
IaaS is another cloud delivery model that allows organizations to host infrastructure without requiring any complicated hardware setup. Business users get on-demand infrastructure resources and components to build customized systems. You can rent your server, networking resources, storage, and virtual machines with CSP (cloud service provider) on a pay-as-you-go model.
Primarily, you need IaaS to reduce capital expenditures and make transformations in operational processes. Businesses do not have to purchase storage, computing, or look for networking options. Moreover, you would require IaaS in the following cases:
Here are some prominent advantages of IaaS:
SaaS (Software as a Service) is a subscription-based cloud software that is ready to be used after paying a certain fee. SaaS can be accessed via a web browser and delivered over the internet. The provider will facilitate the infrastructure, middleware, patch management, network management, and maintenance of the application, which is rendered on demand by the user. The vendor manages the installations and upgrades to provide you with the latest version of the software equipped with upgraded functionalities.
The Software-as-a-service cloud model works as a cloud delivery wherein the provider will host applications by utilizing its servers, networking, or other computing resources. Further, a contract can also be made with an independent software vendor to host the data center. Afterward, SaaS will manage all your operating systems and middleware.
Now, users can get access to the application server after getting access through login credentials. Users need to pay a certain fee as a subscription charge in order to get access to the ready-made solution.
Service Level Agreements (SLAs) are important, as they remain a legal contract between the company and the vendor. They lay down the expectations, such as security, uptime, maintenance, and support, along with the client’s responsibilities. For example, SLAs will play a huge role when a cloud service provider uses your data. In that case, you can confirm the ownership of data through an SLA by stating that you hold the rights to retrieve data and get your data back up at any point in time.
Moving to a hosted cloud environment from on-premise cloud environment is the primary decision that organizations make regarding digital transformation. This makes SaaS relevant. But why?
The SaaS market is rising to $232 billion this year, attributed to a number of factors such as the rise of a mobile-driven world and increased adoption of cloud, and the emergence of AI and machine learning.
Implementing SaaS will benefit your business by creating a world of applications that make it relevant in the market. Let’s learn about its benefits for a better understanding.
You do not need dedicated physical equipment to get started with SaaS. All you need is a subscription, which you can choose as per your need, and you can avail yourself of the software features and services. It can reduce installation costs, unlike conventional systems. Likewise, businesses can avoid costly upfront expenses, making it a cost-effective solution with premium features to operate a business.
A SaaS solution is very easy to deploy. Business owners just require a browser and online access to access the software tools. Unlike conventional software, which takes weeks to implement, SaaS solutions will take only a few minutes to install after you have purchased an enterprise subscription.
Since it works on a subscription-based model, it offers on-demand scalability of resources, which is perfect for a growing business. The pricing models are flexible; you can scale up when demand increases and make it down when the demand decreases. Plus, the SaaS solution can be accessed from anywhere, allowing flexible work-from-home opportunities for your employees. The data and system can be logged in at their comfort, which makes their life easy.
Your SaaS vendor is responsible for providing you with the latest application upgrades along with regular maintenance to address usage bottlenecks. It helps business owners eradicate the need to install or download patches to maintain the software. This will reduce the complexities of IT teams as the vendor will automatically manage everything.
Even with long-established software solutions, there is no assurance of how the software will work. However, SaaS will provide assurance in terms of service. Most providers will provide a guaranteed uptime of 99.99% with top performance. Also, they will provide 24×7 customer support, which shows their willingness to serve customers better.
Conventional software involves painstaking data recovery and management, which can even involve a pricey mechanism. With SaaS, there are automated backups without any user interference, which eliminates this painstaking activity and ensures the uprightness of the data.
Deciding on the right cloud model from a myriad of giants such as Amazon, Microsoft, and Google, with bespoke services, can be a difficult choice. Here are some factors that you should consider:
All three PaaS, IaaS, and SaaS have unique advantages, and understanding these models will help you leverage cloud deployment models more strategically. PaaS is good for hosting your infrastructure so that you can accelerate your application development process. IaaS can quickly deploy your web applications. Moreover, businesses utilize SaaS-based solutions to streamline operations through a ready-to-use software solution. It is always best to consider the key factors before you switch to a cloud platform that certainly brings you long-term success.
