Backend as a Services

Applications are not just about the front end, which is the part that manages the UI (user interface) or visual appearance and components users can interact with. Rather they are full-stack technology, which is the entirety of a computer systems application, and as part of this technology, you also have the backend, which is the side of the technology that manages databases, servers, APIs, etc.

Handling backend functionalities or infrastructure can be complex and time-consuming; hence, an alternative for managing the backend of an application called BAAS (backend as a service) was developed to make building full-fledged applications faster and more efficient.

What is BAAS? Why was it created, and why do we need it? This concept is what we aim to explain in this article, let’s dive in.

When cloud computing emerged in the mid-2000s, it provided scalable infrastructure resources, managed services, and integrations, it paved the way for back-end-as-a-service [BAAS] a far cry away from the traditionally tedious functionalities and complexities involved in building applications.

Baas is a cloud service that provides web app and mobile app developers with ready-made software to build the backend to their frontend applications easily.

It is a cloud service model that handles an application's underground functionality by simplifying and automating backend tasks. BAAS providers have developed software for database management, user authentication, push notifications, and cloud storage, amongst many others.

The idea was to create a service for developers to assign the heavy labor of backend tasks to cloud services. This means that developers didn't have to build a backend from scratch. In short, it’s a ready-to-use solution that provides backend support using software development kits and APIs.

Depending on the BAAS platform, the following features may be provided by the vendor and is necessary for most of the apps developers build:

• Infrastructure Management: Backend-as-a-service (Baas) platform helps developers with the complexity of managing backend infrastructure. The Baas provider sets up and manages the backend infrastructure such as servers, databases, and networking-related capabilities.

• User Authentication: This feature handles authentication and authorization. It allows the integration of authentication methods like OAuth, common email/password systems, etc.

• Push Notification: Backend-as-a-service (Baas) platform provides tools for push notifications - which are targeted and personalized messages sent to the user's device.

• API Management and Integration: Backend-as-a-service (Baas) platform generated APIs for backend services automatically. API gateways manage requests, and responses, and also support integration with external APIs and third-party services.

• Hosting: Baas providers may offer hosting features for developers to deploy and manage web applications.

• Geolocation: Baas offers developers who are developing location-aware applications with features that include; location tracking, geo-fencing, location-based querying, and location analytics functionalities.

• Analytics and Reporting: Backend-as-a-service has tools for data analysis and visualization- to monitor performance and make data-driven decisions to improve the application or business performance.

• Database management: Backend-as-a-service provides a cloud-based database for efficient storage, retrieval, and management of application data. Also, the backend-as-a-service platform provides real-time data streaming and synchronization.

This allows features like real-time chat, real-time notification, and other collaborative functionalities.

• Social Media Integration: Baas platforms allow the incorporation of social media functionality like signup, login, content sharing, and data access.

• Security: Baas platforms have measures/ resources in compliance with regulatory standards to enhance security, and prevent authorized access to client's applications.

• Cloud and File Storage: Backend-as-a-service platform manages file storage using modules for file-sharing management. Baas provider also restores files in case of system failure.

Applications that can implement Backend-as-a-service have functionalities like; vendor and customer profiles, in-app search, list goods and services, user accounts, chats with file sharing and video calling features, comments/reviews features, checkout, delivery options, etc.

These applications may be;

• On-demand services, e.g. e-commerce
• Social network and real-time messaging e.g. discord
• E-commerce apps, and online-stores e.g. eBay
• Productivity Apps e.g. oneNote, Trello

Baas providers support a range of web and mobile frameworks e.g.

• Web framework (e.g. React, Vue, and Angular )
• Mobile development technology e.g. IOS Native( e.g. Swift or Objective -c) and - Android Native (e.g. Java or Kotlin)
• Cross-platform frameworks (e.g. flutter, kotlin )

There are many reasons why BAAS is important and they include;

• Development speed: BAAS speeds the development process, which means, there’s less production and maintenance of the code.

• Faster release time: BAAS speeds up the development process, which means developers can deliver the product to users faster.

• Trust and Efficiency: Developers can rely on the BAAS platform; finding and fixing bugs is much easier, and maintenance and support services are readily available.

• Security: BAAS platforms have built-in security features that protect data from being tampered with or exploited by malicious attacks. The BAAS platform has enough resources to enhance security and comply with necessary regulations.

• Scalability: BAAS infrastructure is scalable meaning that it was created to adapt to the growth of an application.

• Cost-Efficient: Using the BAAS platform for small projects, may not require a full-time developer, which saves on the cost of hiring.

• Cross-Platform Management: The BAAS platform allows developers to manage backend services across different platforms- either web or mobile.

• Third-Party Integration: BAAS platforms offer third-party integrations meaning that developers can incorporate various functionalities in their applications like; database management, geolocation, authentication, etc.

• Re-occurring cost: Adopting backend-as-a-service may require a subscription fee which is constant as long as the service is required. As the project grows requiring more features, so does the cost of usage.

• Reduced Flexibility: Adopting Backend-as-a-service may limit the coding structure of an application. Developers would have to consider the constraints of BAAS platforms when developing an application.

• Proprietor lock-in / Vendor Dependency: The developer depends on the provider which means the backend functionality is merged with the vendor's infrastructure and services. If the provider's service is down, it affects the application.

Also, if you’re dissatisfied with the service, it can be strenuous to move or switch providers.

• Limited Customization: Pre-built features and functions can be limiting especially when the application requires distinctive features or functions.
