Cloud application development services are for companies that need software to run reliably for many users, in several regions or under uneven load, without buying and managing servers. We design and build applications that run on AWS, Microsoft Azure or Google Cloud, and we move existing applications off shared hosting or office servers into a managed cloud setup. The result is an application with its infrastructure written as code, deployed through a pipeline, monitored, backed up and documented, all inside cloud accounts you own.
This work sits inside our custom software development practice. The difference from a standard build is that the hosting design is part of the product: how the app scales, how it recovers from failure, how data is stored and what it costs each month are decided up front, not discovered after launch. If you are searching for a cloud application development company because your current app slows down at peak times, your hosting bill keeps climbing, or nobody on your team can safely deploy a change, this page explains how we approach it.
What Our Cloud Application Development Services Include
Most projects combine several of the items below. We scope them together so the application code and the cloud setup are designed by the same people.
| Service | What it means for you |
|---|---|
| Cloud architecture and cost planning | A diagram of every component, the managed services behind it, how it scales and a monthly hosting estimate at your current and expected traffic. You see the bill before you build. |
| Custom cloud application development | New web applications, APIs and back ends built to run on managed cloud services, with logins, roles, an admin panel and the business features your users need. |
| Cloud migration | Moving an existing app from shared hosting, a single VPS or an on-premise server into containers and a managed database, with a tested cut-over plan and rollback. |
| Serverless and event-driven back ends | Functions and queues for work that arrives in bursts, such as imports, webhooks, image processing and scheduled jobs, so you pay for processing only when it runs. |
| Managed databases and storage | PostgreSQL or MySQL on a managed service, object storage for files, automated backups and point-in-time recovery, configured and tested rather than left on defaults. |
| Infrastructure as code | Every server, database, bucket and permission defined in Terraform or AWS CDK, stored in your repository, so environments can be rebuilt and changes are reviewed like code. |
| CI/CD pipelines and environments | Automated tests and deployments through GitHub Actions, with separate staging and production environments, so releases stop depending on one person. |
| Monitoring, logging and alerts | Error tracking, uptime checks, logs you can search and alerts that go to the right person, plus budget alerts so cost spikes are caught in days, not at month end. |
| Security and access setup | Least-privilege access roles, secrets kept out of the code, encryption in transit and at rest, and separate accounts or projects for production and testing. |
Types of Cloud Applications We Build
Cloud based application development covers many kinds of software. These are the ones we are asked for most, and each shapes the architecture differently.
- SaaS products. Multi-tenant applications where each customer's data must stay separate and the platform has to handle sign-ups, billing and growth. Our SaaS development page covers the product side in more depth.
- Internal business tools. Operations dashboards, approval systems and data tools used by staff in several offices or countries, often with single sign-on through Microsoft Entra ID or Google Workspace.
- Customer and partner portals. Secure areas where clients upload documents, track orders or download reports, usually with file storage and email notifications behind them.
- APIs for mobile and web front ends. The back end that a mobile app, a storefront or a partner integration talks to, built to stay responsive when traffic spikes after a push notification or a campaign.
- Data pipelines and scheduled jobs. Imports from suppliers, nightly syncs between systems, report generation and AI processing that run on a schedule or a queue rather than on someone's laptop.
- Ecommerce back-office services. Inventory sync, order routing and product feed generation that sit behind a Shopify or WooCommerce store and do the heavy lifting the store platform should not.
Cloud-Native Application Development Services vs Moving an App to the Cloud
A cloud-native application is designed from the start to use managed cloud services: containers or functions instead of a hand-configured server, a managed database instead of one installed on a virtual machine, queues for background work and configuration kept outside the code. A cloud-hosted application is a traditional app that happens to run on a cloud server. Both are valid, and the right choice depends on the app's age, traffic and budget.
| Approach | What it involves | When it makes sense |
|---|---|---|
| Rehost (lift and shift) | Move the app as it is onto cloud virtual machines with minimal code changes. | An aging app that needs to leave a failing server quickly, before a later rebuild. |
| Replatform | Containerize the app with Docker, move the database to a managed service and add a deployment pipeline. | Most migrations we do. Large gains in reliability for modest code changes. |
| Refactor to cloud-native | Break out background work into queues and functions, add auto-scaling and redesign parts of the app around managed services. | Apps with heavy or unpredictable load, or a product you plan to grow for years. |
| Build cloud-native from scratch | Design the application and its infrastructure together from day one. | New products and internal systems where there is no legacy code worth keeping. |
We do not push every client toward Kubernetes and microservices. A well-built monolith in a container, with a managed database and a queue, covers the needs of most growing businesses and costs far less to run and maintain. We add complexity only when your load or team structure calls for it.
How Our Cloud Application Development Process Runs
- Cloud architecture sprint (1 to 2 weeks). We gather requirements and user stories, review any existing code and hosting, and estimate traffic and data volumes. The output is an architecture diagram, a recommended provider and services, a written scope and a monthly hosting cost estimate. The sprint is useful even if you build with another team.
- Foundation setup (1 to 2 weeks). We create the cloud accounts or projects in your name, set up access roles, write the infrastructure as code and build the CI/CD pipeline. Staging and production environments exist before the first feature is written, so every change from then on is deployed the same way.
- Build in two-week cycles. Features are built, tested and deployed to staging every two weeks, and you review working software rather than screenshots. An MVP with core launch features typically takes 8 to 14 weeks, depending on integrations and the number of user roles.
- Testing under realistic conditions. Beyond automated tests, we run load tests with tools such as k6 against staging to see how the app behaves at several times your expected traffic, and we test that backups actually restore.
- Launch or cut-over. For new apps, we launch in a quiet window with monitoring watched closely. For migrations, we rehearse the move in staging, sync data, switch DNS with a low TTL and keep the old environment available for a planned rollback period.
- Handover and ongoing care. You get the runbook, architecture documents and a walkthrough recording. After a support period, you can keep us on a monthly plan through our software maintenance services or run the app with your own team.
AWS Cloud Application Development Services
Most of our cloud projects run on Amazon Web Services, because its managed services cover almost every need and most developers you might hire later already know it. As an AWS cloud application development services company, we work in plain, well-documented services rather than niche ones, so the setup stays understandable for whoever maintains it next.
- Compute: ECS on Fargate for containers without managing servers, AWS Lambda for functions, App Runner for simple web services and EC2 when an app needs a full virtual machine.
- Data: Amazon RDS or Aurora for PostgreSQL and MySQL, DynamoDB for high-volume key-value data, ElastiCache for Redis and S3 for files and backups.
- Delivery and messaging: CloudFront for content delivery, SQS and EventBridge for queues and events, and SES for transactional email.
- Identity and security: IAM roles with least privilege, Cognito for user sign-in where it fits, Secrets Manager for credentials and AWS WAF in front of public endpoints.
- Operations: CloudWatch for logs, metrics and alarms, AWS Budgets for cost alerts and AWS Organizations to keep production, staging and sandbox accounts separate.
Choosing a Cloud Development Platform: AWS, Azure or Google Cloud
The best cloud application development platform is usually the one your company already uses or can staff for. All three major providers can run a typical business application well. The differences show up in your existing contracts, identity setup and the managed services you need.
| Provider | Typical fit | Services we commonly use |
|---|---|---|
| AWS | Most startups and growing companies; the widest choice of managed services and the largest pool of developers. | ECS Fargate, Lambda, RDS, S3, CloudFront, SQS |
| Microsoft Azure | Companies already on Microsoft 365 and Entra ID, or with existing Microsoft licensing agreements. | App Service, Azure Functions, Azure SQL Database, Blob Storage, Container Apps |
| Google Cloud | Teams on Google Workspace, data-heavy products and apps that benefit from BigQuery. | Cloud Run, Cloud SQL, Cloud Storage, Pub/Sub, BigQuery |
| Simpler hosts (DigitalOcean, Hetzner) | Small, steady workloads where a full cloud provider adds cost and complexity without benefit. | Managed databases, droplets or servers with Docker |
We will tell you when a simpler host is the better choice. A small internal tool with steady use does not need the same setup as a public API that has to absorb traffic spikes.
IaaS, PaaS and SaaS in Cloud App Development
Cloud services are grouped into three models, and a single application often uses all three. Knowing which layer you are paying for helps you judge who is responsible for what.
| Model | What the provider manages | Examples |
|---|---|---|
| IaaS (infrastructure as a service) | The physical hardware, networking and virtualization. You manage the operating system and everything above it. | Amazon EC2, Azure Virtual Machines, Google Compute Engine |
| PaaS (platform as a service) | Hardware, operating system and runtime. You deploy code and manage your data. | AWS Elastic Beanstalk, Azure App Service, Google App Engine, Heroku |
| SaaS (software as a service) | The whole application. You configure it and use it. | Microsoft 365, Salesforce, Shopify |
Our cloud development services lean on PaaS and managed services where possible, because every layer the provider manages is one fewer layer you pay someone to patch.
Cloud Application Deliverables and What Good Looks Like
At the end of a build or migration you receive more than a working app. These are the outputs we hand over, and the measures we use to judge whether the cloud setup is healthy.
What you receive
- Application source code and infrastructure code in a Git repository you own, on GitHub or your preferred host.
- An architecture diagram and a short decision record explaining why each major service was chosen.
- Staging and production environments, deployed only through the CI/CD pipeline.
- Monitoring dashboards, error tracking with Sentry or the provider's tools, and alert routing agreed with your team.
- A runbook covering deployments, rollbacks, restoring from backup, rotating secrets and scaling.
- A cost breakdown by service with budget alerts configured in your account.
How we judge a healthy cloud app
- Deployments are routine and take minutes, with a rollback path tested at least once.
- A restore from backup has been carried out in staging and the time it took is written down.
- Error rates and response times are visible on a dashboard, with alerts on the thresholds you care about.
- The monthly bill matches the estimate, or the reason for any difference is understood.
- Nobody needs to log in to a server by hand to keep the app running.
Cloud Application Development Services Pricing
Cloud work is priced in three ways. The architecture sprint is a fixed fee. A new cloud app MVP or a migration is a fixed price against a written scope, starting from the levels shown in the plans. Cost depends mainly on the number of user roles and features, the integrations involved, how much data needs migrating, and whether you need features such as multi-region hosting or strict data residency. Your cloud provider bills you directly for hosting, so you always see that cost separately.
Cloud hosting (AWS, Azure or Google Cloud) is billed to your own account. Most small apps run on $100 to $300 a month.

Cloud Software Development Services: Agency, Freelancer or In-House
Each option can work. The right one depends on how much ongoing change you expect and whether you can hire someone who understands both the application and the infrastructure.
| Option | Strengths | Risks |
|---|---|---|
| In-house team | Deep product knowledge and full-time attention. | Hiring for both cloud and application skills is slow and costly, and one departure can leave nobody who understands the setup. |
| Freelancer | Flexible and affordable for a defined task. | Infrastructure often lives in the freelancer's account or head, with little documentation when they move on. |
| Cloud application development company | Architecture, code and DevOps handled together, with documentation and continuity built in. | Needs a clear owner on your side to make product decisions and accept work. |
A common middle path is to have us build and document the platform, then hand day-to-day development to your own hires while we stay on a small support plan for the infrastructure.
Cloud Based Application Development Mistakes We Fix
Many of our cloud projects start as rescues. These are the problems we find most often, and each one is cheaper to avoid than to fix later.
- No budget alerts. A forgotten test cluster, an unbounded log group or a looping function can run for weeks before anyone looks at the invoice.
- Everything in one account. Production, testing and personal experiments share one cloud account, so a mistake in testing can touch live data.
- Credentials in the code. Access keys committed to a repository, sometimes a public one. We move them into a secrets manager and rotate them.
- Click-built infrastructure. Resources created by hand in the console with no record of how they were configured, so nobody can rebuild them with confidence.
- Over-engineering. Kubernetes, service meshes and a dozen microservices for an app with a few hundred users, leaving a small team maintaining a platform instead of a product.
- Backups that were never restored. Automated snapshots exist, but nobody has checked that they restore, or how long it takes.
- Ignoring data transfer costs. Moving large files between regions or out to the internet can cost more than the servers. We design storage and delivery with this in mind.
- Accidental lock-in. Some provider-specific services are worth using. Others tie you to one vendor for little gain. We make that trade-off explicit in the architecture record.
Why Choose 95 Solutions as Your Cloud Application Development Company
- We run our own software in production. Our team built and maintains the custom PHP and SQLite CMS behind this site and Boiler Decoder, and co-builds AM Jarvis, a SaaS suite for Shopify and WooCommerce stores. We deal with deployments, monitoring and hosting bills for our own products every month.
- Senior-led architecture. Mustafa, who holds a BS in Computer Science, reviews every architecture decision, so the person setting the plan understands both the code and the business case.
- Your accounts, your code. Cloud accounts, repositories and domains are created in your name from the first week. You can remove our access at any time.
- Cost honesty. We estimate the monthly hosting bill before the build and set budget alerts on day one. If a simpler host fits better than a major cloud provider, we say so.
- Working hours that overlap yours. Our remote team covers UK business hours and the full US business day. Contracts and invoices are in USD from our US LLC.
Who Our Cloud Development Services Are For
A good fit
- Startups and growing companies building a SaaS product, portal or API that needs to scale without a rebuild.
- Businesses running an important app on shared hosting or a single office server that worries them.
- Teams whose current cloud setup works but is undocumented, expensive or understood by one person.
- Companies that want the cloud setup built properly once, then maintained by their own developers.
Probably not a fit
- Large enterprise programs that require a vendor holding formal certifications such as SOC 2 or ISO 27001. We do not hold those.
- Projects that need a staffed operations center watching systems around the clock.
- Simple brochure websites. A managed website platform will serve you better than custom cloud infrastructure.
If you are searching for cloud application development near you, note that our team works remotely and runs projects through video calls, shared boards and written specifications, with hours that cover the US and UK business day.
