A cloud-based app also called an IaaS app, is an Internet-running application with parts stored on the cloud and operated via the internet.
An IaaS app could be anything from a business service, database, game console, or social networking site to just about anything you can think of.
Any app consists simply of processing logic and data stored as code and therefore requires a very large space to run.
This means less space for storing applications and data on the server-side and therefore reduced costs for an enterprise.
There are different ways to approach cloud computing for your company but here are some of the most common. scalability refers to how elastic your cloud apps are.
In other words how easy it is to add more capacity to your cloud computing model once your current needs have been satisfied.
Infrastructure as a service is one of the ways cloud apps are delivered to end-users.
This is delivered via a proprietary application platform that is managed by the provider and consists of several appliances – central storage, management systems, application servers, and load balancers among others.
There is no need for any form of custom software development since the infrastructure already exists and is managed on behalf of the user.
This reduces costs and increases the ability to scale up easily once the demand for cloud apps increase.
Types of Apps
Private Cloud-Based App Development
is another way to deliver your app globally. Some cloud service providers offer private dev solutions which include tools, guides, and infrastructure to help you develop your app.
The provider maintains a separate development environment consisting of developers. As a user, you only pay for what you use – there are no additional fees for using their private cloud development tools and infrastructure.
You only pay for what you require, and can therefore run as many instances as you need, with or without paying for any additional services.
Hybrid Cloud-Based App Development
is a blend of the public and private cloud platforms. With this type of solution, two or more different platforms are offered to the client.
It uses both public cloud platforms and private cloud platforms. It is possible to run your own application from either host. The client can still access the same information and resources regardless of whether it is in the public or private cloud platform.
IAAS is the industry standard for cloud-based application development. It is a way of consolidating several business apps into a single, easy to deploy, manage and use platform.
IAAS comes with a series of advantages including it taking away the need for complex infrastructure and app setups; it allows easy access to app data irrespective of where they are hosted.
it also allows easier management and tracking of mobile device usage. However, the biggest disadvantage of IAAS is that it comes with very high costs as compared to PaaS or SaaS model.
It also requires a considerable amount of training and knowledge about the use of the underlying infrastructure.
PaaS is the set of software products developed by some companies which aim at providing IT solutions to end-users via cloud application development.
PaaS includes two types of development – one is Platform as a Service (PaaS) and another is Software as a Service (SaaS).
The advantages of using PaaS are that they offer a flexible environment to operate and use compared to IAAS or SaaS model; they are very easy to deploy compared to other models.
They offer a control mechanism to control and monitor the deployment of the application; they provide a uniform infrastructure to ensure reliability and performance.
The main disadvantages of using PaaS are that it comes with very high costs as compared to other models; it is not flexible and can easily be customized.
The usage of both PaaS and SaaS in the development of enterprise apps can help in reducing the cost involved in developing the app. However, it depends on the type of app that needs to be developed and its complexity.
The main types of apps available in the market are enterprise, middleware, and app platforms. Enterprise app refers to an app whose objective is to give user experiences outside the boundaries of an organization.
Middleware app architecture can be broadly divided into three categories – infrastructure-assembled, platform-assembled and modular.
