Rackspace Cloud Deployment Models

Introduction

In the cloud, you can deploy your software in one of three basic models: Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). Each deployment model has its own benefits and drawbacks.

Software as a Service (SaaS)

Software as a Service (SaaS) is a software delivery model that allows users to access applications over the web. SaaS is often associated with subscription-based models, where customers pay monthly fees to use the application or service.

The main benefit of SaaS is that it allows companies to outsource the management and maintenance of their applications while still being able to access them from anywhere. This means that instead of having dedicated on-premise hardware and software infrastructure, businesses can rely on cloud providers like Rackspace or Microsoft Azure that provide these services at scale with high availability standards.

Since there are no upfront costs involved in setting up an instance on these platforms, this type of deployment model has become very popular among small businesses who want easy access without having to invest heavily in capital expenditures (CAPEX).

Platform as a Service (PaaS)

Platform as a Service (PaaS) is an application development model that allows software developers to build, test and deploy applications without the need to purchase and maintain the underlying infrastructure.

In other words, it’s an abstraction layer between you and your cloud provider’s infrastructure. You can think of it as an operating system for your cloud-based application–it provides everything you need for running apps in their environment: hardware configuration, middleware services like databases or message queues, libraries for common tasks like authentication and authorization; even tools like static code analysis integrated into IDEs like Visual Studio Code or IntelliJ IDEA

Infrastructure as a Service (IaaS)

In the IaaS model, you pay for computing resources on demand and only for what you use. You can allocate resources dynamically and on-demand to meet changing demands of your applications. This allows organizations to be agile in their approach to cloud deployment, as well as reduce costs by using only what they need at any given time instead of having excess capacity sitting around not being used.
