Where to host your mobile app?

Hosting a mobile application backend is one of the essential requirements for any application developer/company. A robust and agile backend directly impacts the level of performance and reliability an application offers to end-users. While there are many backend options available right now, it is essential not to be overwhelmed.

The first thing to consider is whether one needs an IaaS, PaaS, or BaaS for the application requirements. Then there is the prospect of choosing a suitable backend service provider.

Here is a summary of the article:

  • Hosting options categories (IaaS, PaaS, and BaaS)
  • BaaS and PaaS | Comparison
  • PaaS and IaaS | Comparison
  • Top 10 hosting services for a mobile app

Read on to explore the different types of backends and some of the leading providers out there.

Backend options to host your mobile app

There are mainly three different cloud categories to host your mobile application. Changing from IaaS to PaaS and from PaaS to BaaS cloud service models adds service layers to your application. Take a look at the overview given below to get a better idea.

  • IAAS = Data Center + Servers + Storage +Networking
  • PAAS = IAAS + Deploy + Manage + Scale
  • BAAS = PAAS + Features to a Build Backend

Some more details below:

Service OfferingDefinition
IaaSInfrastructure-as-a-Service, or IaaS, is a cloud computing model that gives users network and storage resources and basic computing to customers on an on-demand basis and based on a pay-as-you-go model. IaaS lets end users scale and minimize resources based on their requirements. It reduces the need for steep upfront capital costs or expenses of owned infrastructure.
PaaSPlatform as a service (PaaS) is a concept describing a platform offered to users as an integrated solution, over the Internet service, or solution stack. The solution stack can be software systems or a set of components utilized to develop functional services and products. These include web applications that use a web server, operating system, programming language, and database. The solution stack can deliver components such as OS, database, and middleware.
BaaSBackend-as-a-Service (BaaS) is a cloud service infrastructure model utilized by developers across the globe. Under a BaaS setup, developers can focus on writing and maintaining front-end code without handling backend aspects. BaaS vendors give users prewritten software for actions on servers, including database management, user authentication, push notifications, remote updating, hosting, and cloud storage.

Differences between PaaS vs BaaS

Using PaaS enables users to reduce costs related to the purchase, maintenance, and configuration of infrastructure. On the other hand, using BaaS allows developers to perform fast and straightforward management of your back-end services. The points given below will give you a better idea about the fundamental differences.

Do provide Do NOT provide
PaaSPaaS will provide mechanisms including:
– CDN – Content distribution networks
– Automated deployment
– Load balancers
However, a PaaS does not generally provide these:
– Database management
– Business Logic
– Frontend Code
BaaSBaaS gives its users mechanisms including:
– Out of the box backend features such as authentication, social login, email notification, and push-notifications.
– Database management- Serverless environment
However, a BaaS does not provide:
Frontend code
Flexibility equivalent to that of a PaaS
Server level access

Both PaaS and BaaS offer their own set of advantages for users. The decision to use either a PaaS or BaaS offering generally depends on the precise development process requirements of a user, and the outcomes of such solutions.

Now that you have a general idea about PaaS and BaaS let us look at some key differences between IaaS and PaaS. It will make it easier for you to compare all the three types.

Differences between IaaS and PaaS

Knowing the difference between IaaS and PaaS is vital for many developers who want to choose the right mobile backend. It is essential to understand that IaaS refers to the services associated with the cloud infrastructure. It is also a computing solution encompassing scalable and automated resources.

IaaS is also a full-fledged service to monitor and access storage, networks, computing resources, and other types of services. By opting for the IaaS computing model, businesses can buy on-demand resources whenever required. They do not need to purchase hardware right away for meeting rises in resource demand.

Conversely, platform as a service refers to cloud platform services that enable application developers to access cloud tools for software. PaaS is more widely used for applications compared to IaaS. With a platform as a service, developers gain access to a robust framework that can be used for developing powerful and customized applications with efficiency. 

Third-party service providers or enterprises can manage all resources of servers, storage, and networking solutions. Developers and businesses can use the resources made available to them through a PaaS and achieve optimal application management.
