Cloud computing has transformed the way businesses operate by providing flexible, on-demand access to technological resources. Among the variety of services provided via the cloud, IaaS, PaaS, and BaaS are pivotal. Standing for Infrastructure as a Service, Platform as a Servic, and Backend as a Service, these models each offer unique benefits and considerations. This article aims to elucidate these cloud service models, assisting you in discerning the best fit for your needs.
In an IaaS model, businesses rent essential infrastructure — servers, virtual machines, storage, networks, operating systems — from a cloud provider on a pay-as-you-go basis.
IaaS is well-suited for businesses looking to create cost-effective, scalable, and flexible infrastructure without the burden of physical hardware.
Renowned IaaS providers include Amazon Web Services (AWS), Google Cloud Platform (GCP), and Microsoft Azure. (See this article for a comparison of AWS, Azure, and GCP.)
PaaS provides a platform including both hardware and software tools over the internet. This model abstracts developers from the underlying infrastructure complexities, enabling them to focus on developing their applications.
PaaS is ideal for developers aiming to concentrate on their coding without the need to manage the underlying infrastructure.
Google App Engine, AWS Elastic Beanstalk, and Microsoft Azure App Services are among the leading PaaS providers.
BaaS refers to a service model where backend services are delivered over the Internet on a subscription basis.
BaaS is relevant for businesses, particularly startups, needing to launch operations quickly and with minimal upfront cost. BaaS solutions eliminate the need for in-house server-side development by providing ready-to-use backend services, thus speeding up the process of application development.
Notable BaaS providers that offer alternatives to traditional self-managed backends include Firebase and AWS Amplify.
Reviewing the pros and cons of these cloud service models in the context of your own use case will empower you to make more informed decisions, ensuring that your chosen solution aligns with your specific needs and goals.
As you consider your options for a provider, we’d like to explain how Encore is different. While we call it a backend development platform, it’s altogether different from your other PaaS providers.
