Cloud application development built around managed services

We write software that uses the cloud on purpose (managed databases, queues, object storage and functions) so your team spends its time on features rather than on servers.

Definition

What is Cloud Application Development?

Cloud application development is the design and coding of software intended to run on cloud platforms, using the platform's managed services instead of reproducing them on self-managed servers. A cloud-native application is typically stateless, packaged in containers or functions, stores files in object storage, uses a managed database and is deployed through an automated pipeline. The aim is software that scales, recovers and ships changes with less manual operations work.

Putting an application on a cloud server does not make it a cloud application. Software written for one machine keeps uploaded files on local disk, holds sessions in memory, runs scheduled jobs from a crontab and assumes the database is on localhost, so it cannot run a second copy, cannot survive a server replacement and cannot take advantage of anything the platform offers. Building cloud-native from the start avoids an expensive rewrite later.

Business challenges

Why running on a cloud server isn't enough

01

Applications tied to one server

Local file storage, in-memory sessions and hard-coded paths make horizontal scaling and server replacement painful or impossible.

02

Undirected service sprawl

Cloud catalogs list hundreds of services. Choosing too many creates an application that is hard to run locally, hard to debug and expensive to operate.

03

Lock-in worries

Teams fear that using any proprietary managed service will trap them, so they avoid useful ones, or use them everywhere without an exit plan.

04

Costs that grow with usage in surprising ways

Per-request pricing, data transfer and chatty function calls can make a successful feature unexpectedly expensive.

What Digihub provides

Our Cloud Application Development service

01

Cloud-native application design

Service boundaries, data model, state handling and which managed services each component uses, documented before development starts.

02

Backend and API development

Stateless APIs in Node.js or Python, designed to run as multiple instances behind a load balancer, with configuration supplied through the environment.

03

Serverless functions and event processing

Functions for scheduled jobs, webhooks, file processing and queue consumers where event-driven execution genuinely suits the work.

04

Containerized services

Docker images for services that need longer-running processes, deployed to a managed container service or Kubernetes when the scale justifies it.

05

Managed data and storage

Managed PostgreSQL, MySQL or MongoDB, object storage for files, caches and message queues, configured with backups and access controls.

06

Pipelines and environments

Automated build, test and deployment to separate development, staging and production environments from the first sprint.

Included capabilities

  • Stateless services that scale horizontally
  • Object storage for uploads and generated files
  • Background jobs through queues
  • Scheduled and event-triggered functions
  • Twelve-factor configuration via environment
  • Structured logging and tracing hooks
  • Health checks and graceful shutdown
  • Local development that mirrors the cloud setup
  • Infrastructure defined as code with the app
Business benefits

What Cloud Application Development changes for your business

01

Less infrastructure to babysit

Patching databases, rotating disks and scaling queues become the provider's job instead of your team's.

02

Scale when it is needed

Stateless services can run more copies under load and fewer when traffic drops.

03

Faster, safer releases

Automated pipelines and identical environments make deployments routine instead of risky events.

04

Deliberate portability

Containers and standard databases keep the core of the application movable, with provider-specific services isolated behind clear interfaces.

Use cases

Where it makes the biggest difference

SaaS platforms

Multi-tenant products where many customers share one deployment and load varies through the day.

Customer portals and mobile backends

APIs serving web and mobile clients, with file uploads, notifications and authentication handled by managed services.

Data and document processing

Uploaded files, imports or webhooks processed asynchronously by queue workers or functions instead of blocking users.

Internal business systems

Line-of-business tools that need to be reliable and accessible from multiple offices without an on-premises server room.

Process

How a cloud-native build runs

Pipelines and environments come first, so every feature ships the same way.

  1. Scope

    Product goals, users, expected load and integration points, captured as a prioritized backlog.

  2. Architect

    Service and data design, choice of managed services, and a running-cost estimate for the expected usage.

  3. Set up foundations

    Repositories, environments, CI/CD pipeline and infrastructure as code before feature work begins.

  4. Build iteratively

    Short development cycles with working software deployed to staging for review at the end of each one.

  5. Test

    Automated unit and integration tests plus load testing of the paths that will see the most traffic.

  6. Launch

    Production deployment with monitoring, alerting and a rollback path in place.

  7. Operate and improve

    Usage and cost reviewed after launch, with the architecture adjusted as real traffic patterns emerge.

Security & scalability

Security, quality and scale

No secrets in code

Credentials come from the platform's secrets manager or environment, never from the repository.

Scoped service permissions

Each function and service gets an identity with only the permissions it needs.

Private data tier

Databases and caches sit on private networks, reachable only by the application.

Scalability under load

Load tests before launch identify the component that will saturate first, so it can be sized or redesigned.

Why Digihub

What working with us looks like

Developers who also run infrastructure

Our team builds the application and operates the cloud underneath it, so design decisions account for both.

Managed services where they pay off

We use a managed service when it removes real operational work, not because it is new.

Cost estimated with the design

You see an expected running cost before development commits you to an architecture.

Full product stack

The same company can deliver the web front end, the mobile app and the cloud backend that serves both.

Pricing

What it costs

Fixed-price packages with the scope written down, paid stage by stage. Your project goes live once it's fully paid.

From $1,200£900AED 4,400Rs 120,000 per project

Fixed-price CI/CD and cloud migration projects, plus monthly plans for managed servers.

FAQ

Cloud Application Development: questions we hear most

What makes an application cloud-native?

A cloud-native application is built to run as replaceable, horizontally scalable instances that rely on managed services for state. In practice that means no local file storage, configuration from the environment, a managed database, automated deployment and health checks the platform can act on.

Should we build our application on serverless?

Serverless suits event-driven, intermittent or spiky work, but it is not the best fit for every workload. Long-running processes, constant high traffic or heavy local development needs often run better and cheaper in containers. Many applications we build use both: containers for the main API and functions for background events.

How do you avoid vendor lock-in?

We keep the core of the application portable (containers, standard databases such as PostgreSQL, and infrastructure as code) and isolate provider-specific services behind small interfaces. Some lock-in is a reasonable trade for less operational work; the aim is to choose it knowingly.

Which cloud provider do you build on?

We build on AWS, Google Cloud, Azure and simpler providers such as DigitalOcean, depending on the client's needs and existing accounts. The application design is largely the same; the managed services used and their pricing differ.

Can you make our existing application cloud-native?

Yes, usually in stages. Typical first steps are moving file storage to object storage, externalizing sessions and configuration, containerizing the application and adding an automated pipeline. That work is often done as part of a cloud migration or legacy modernization project.
