Cloud challenges

Why cloud application development needs specialist expertise

Moving to the cloud is not a simple infrastructure swap. Cloud-native development requires different architecture patterns, security models, and operational practices.

Scaling beyond on-premises limits

On-premises infrastructure imposes hard ceilings on performance, availability, and geographic reach. Cloud-native architecture removes those limits with auto-scaling, multi-region deployment, and managed services that handle peak demand without manual intervention.

Security and compliance in the cloud

Moving to the cloud shifts your security model. Identity, network isolation, encryption, and audit logging all need to be designed for a shared-responsibility environment. Get it wrong and you trade old risks for new ones.

Legacy system integration

Most organisations are not starting from scratch. New cloud applications need to coexist with legacy databases, on-premises systems, and third-party SaaS platforms. Integration strategy determines whether you get a clean architecture or a fragile bridge.

Cost visibility and control

Cloud spend can escalate quickly without governance. Effective cloud application development includes cost modelling, resource tagging, auto-shutdown policies, and right-sizing from day one.

What we deliver

Cloud application capabilities on Azure

Every application is built on Azure using cloud-native patterns and infrastructure as code. No manual configuration, no environment drift.

Azure-Native Architecture

We design cloud applications on Azure using the services that fit the workload: Azure Kubernetes Service (AKS) for container orchestration, Azure Functions for serverless compute, Azure SQL and Cosmos DB for data, and Front Door for global load balancing.

Cloud-Native Patterns

Microservices, event-driven architectures, CQRS, and the 12-factor app methodology. We build applications that take full advantage of the cloud rather than treating it as a remote data centre.

Infrastructure as Code

Every environment is defined in Azure Bicep templates: repeatable, version-controlled, and auditable. No manual configuration, no environment drift, no surprises between staging and production.

CI/CD and DevOps

GitHub Actions or Azure DevOps pipelines automate build, test, and deployment. Every change goes through automated quality gates before it reaches production. Deployments are zero-downtime by default.

AI-Enhanced Cloud Applications

Azure AI Foundry, Azure OpenAI, and Semantic Kernel integrate AI capabilities directly into your cloud application. Document intelligence, natural language interfaces, and recommendation engines built on the same platform as your core application.

Security by Design

Managed identity, network isolation with Virtual Networks and Private Endpoints, encryption at rest and in transit, and automated vulnerability scanning. We are ISO 27001 certified and Cyber Essentials Plus certified.

Timeline

Cloud development project phases

A typical cloud application engagement from strategy through to production and beyond.

Four phases of cloud application development: strategy and architecture, foundation sprint, iterative delivery, launch — A four-phase cloud application development timeline. Phase 1, strategy and architecture, takes 1-2 weeks: architecture design covers Azure service selection, the cost model, and the target state, and a compliance review covers cloud readiness and identifies constraints. Phase 2, the foundation sprint, takes 2-3 weeks: infrastructure covers Azure IaC, CI/CD pipelines, and environments, and security controls put identity, monitoring, and access policies in place. Phase 3, iterative delivery, is the highlighted phase and runs in two-week sprints: sprint delivery uses AI-augmented agile sprints with regular demos, and quality assurance applies automated tests and code review every sprint. Phase 4, launch and support, covers go-live and beyond: go live is a staged rollout, production cutover, and hypercare, followed by ongoing operations covering monitoring, managed support, and improvements.

How we deliver

Cloud development, accelerated by AI

AI-augmented development (Cursor, Claude Code) means we deliver cloud applications 40-50% faster without compromising on architecture or security.

Step One 1-2 weeks

Cloud Strategy and Architecture

We assess your requirements, existing systems, compliance constraints, and cloud readiness. You receive a target architecture, Azure service selection rationale, cost model, and delivery roadmap before any code is written.

Step Two 2-3 weeks

Foundation Sprint

We establish the project foundation: Azure infrastructure as code, CI/CD pipelines, monitoring, identity, and security controls. A walking skeleton proves the architecture end-to-end before feature development begins.

Step Three

Iterative Delivery

Agile delivery in two-week sprints with AI-augmented development (Cursor, Claude Code) accelerating every phase. Working software is deployed continuously, with regular demos and stakeholder check-ins keeping the project aligned with business goals.

Step Four

Launch and Ongoing Support

Production deployment with comprehensive monitoring, documentation, and knowledge transfer. Our managed application support team provides SLA-backed maintenance, ensuring your cloud application stays performant, secure, and cost-efficient.

"We'd outgrown our off-the-shelf solution. Stability was a real issue: members couldn't always book classes, which was a crisis for us. Talk Think Do built something that scales with our ambitions, stable, flexible, and ready for the future."

FAQ

Cloud application development: frequently asked questions

Are you an Azure development company in the UK?

Yes. Talk Think Do is an Azure application development company based in Bournemouth, Dorset, working with organisations across the UK. Azure and .NET have been our core stack since we were founded in 2014. We build on services including Azure Kubernetes Service, Azure Functions, Azure SQL, and Cosmos DB, with every environment defined in Bicep and deployed through automated pipelines.

We are a Microsoft Solutions Partner with designations in Digital and App Innovation (Azure) and Infrastructure (Azure), plus the DevOps with GitHub on Azure specialisation. We are ISO 27001 certified and Cyber Essentials Plus certified.

What is cloud application development?

Cloud application development is the process of building software that runs on cloud infrastructure rather than on-premises servers. Cloud-native applications are designed to take advantage of managed services, auto-scaling, and distributed architectures. They are typically more resilient, scalable, and cost-efficient than traditional hosted applications. Cloud builds are one strand of the full application development services we provide.

Why choose Azure for cloud application development?

Azure is the natural choice for organisations already using Microsoft technologies (.NET, SQL Server, Active Directory). It offers the broadest range of managed services for enterprise workloads, strong compliance certifications (including UK government frameworks), and deep integration with GitHub and DevOps tooling. Talk Think Do is a Microsoft Solutions Partner with designations in Digital and App Innovation (Azure) and Infrastructure (Azure), plus the DevOps with GitHub on Azure specialisation.

How much does cloud application development cost in the UK?

A focused cloud application MVP typically takes 2-10 weeks. Projects sit within our published band of £25,000 to £100,000+ depending on scope. These estimates include architecture, development, infrastructure setup, and initial deployment. Our AI-augmented development approach delivers 40-50% faster than traditional methods. See our pricing guide for more detail.

Can you migrate an existing application to the cloud?

Yes. We use the 6 Rs framework (rehost, replatform, refactor, rebuild, replace, retire) to assess each component of your existing system and determine the right migration strategy. Not everything needs rebuilding. Our legacy application modernisation service covers the full spectrum from lift-and-shift to complete cloud-native rebuilds.

How do you manage cloud costs?

Cost governance is built into our architecture process. We model expected Azure consumption before development starts, implement resource tagging for cost attribution, configure auto-scaling policies to match actual demand, and use reserved instances where workloads are predictable. Monthly cost reviews are part of our managed support service.

What cloud security certifications do you hold?

Talk Think Do holds ISO 27001 certification and Cyber Essentials Plus certification. We are an approved Government Commercial Agency (GCA) supplier on G-Cloud 15 and DOS 7. Our security practices include threat modelling, infrastructure-as-code review, automated vulnerability scanning, and identity-first access control on every project.

Can public sector organisations buy Azure application development through G-Cloud?
