Frequently Asked Question

All Your Questions Answered

Our answers cover the technical, operational and commercial considerations UK businesses commonly raise when planning a cloud application, including architecture, security, platforms, migration, scalability, delivery and ongoing support.

Cloud Application Development is the process of designing, building and operating software that uses cloud infrastructure or managed cloud services. It can include web interfaces, mobile backends, APIs, databases, automation, analytics and integrations.

A cloud-based application runs in a cloud environment but may retain a traditional architecture. A cloud-native application is designed specifically for cloud capabilities such as managed services, containers, serverless computing, automated deployment and flexible scaling.

AWS, Microsoft Azure and Google Cloud Platform all provide extensive cloud services. The right choice depends on your existing technology, workload, compliance needs, team expertise, integrations, geographic requirements and commercial priorities.

Costs depend on application scope, user roles, integrations, data requirements, security controls, architecture and support needs. ZakCodeX estimates projects after discovery rather than applying one fixed price.

A focused cloud application may take several weeks, while a multi-module SaaS, CRM, ERP or data platform can require several months. Timelines depend on scope, integrations, migration needs and approval cycles.

Yes. Cloud Application Modernisation may include architecture restructuring, API development, containerisation, database improvements, automated deployment or selected migration to managed cloud services.

We develop SaaS platforms, ecommerce systems, mobile backends, AI products, customer portals, internal tools, CRM and ERP systems, analytics platforms, workflow applications and integration services.

Scalability may involve stateless services, autoscaling, load balancing, caching, queues, efficient databases and workload separation. We select patterns according to actual demand rather than adding unnecessary complexity.

Yes. We use services such as AWS Lambda, Azure Functions and Google Cloud Run for APIs, scheduled tasks, event processing and workloads that suit a serverless operating model.

Yes. We use Docker for consistent application packaging and Kubernetes where orchestration requirements justify it, including Amazon EKS and Azure Kubernetes Service. Simpler workloads may use Amazon ECS or managed platforms.

We address identity, role-based access, encryption, secret management, network controls, secure development, dependency updates, audit logging, monitoring and backup according to the system's risk profile.

Cloud architecture can support relevant compliance requirements through access controls, encryption, logging, retention policies and appropriate data locations. Compliance remains a shared organisational responsibility and may require specialist legal or regulatory review.

Infrastructure as Code defines cloud resources in version-controlled files using tools such as Terraform. It improves consistency, reviewability and repeatability across development, testing and production environments.

Yes. We configure CI/CD workflows to automate code checks, testing, builds and deployments, with environment controls, approval steps and rollback procedures appropriate to the application's risk level.

Yes. Our API development services connect applications with CRM, ERP, payment, ecommerce, marketing, communication, identity and analytics platforms using APIs, webhooks and secure data exchange.

We implement application logs, infrastructure metrics, error tracking, tracing and alerts. Observability helps teams identify failures, understand bottlenecks and make informed optimisation decisions.

We define backups, retention, replication and restoration procedures according to business requirements. Disaster recovery planning also considers dependencies, recovery objectives and regular testing of critical processes.

Yes. We design multi-cloud and hybrid solutions where there is a clear operational, integration, resilience or governance reason, while avoiding unnecessary complexity and duplicated management overhead.

Cloud applications support Healthcare, Real Estate, Ecommerce, Finance, Legal, Education, Manufacturing, Logistics and SaaS, as well as Customer Support, Sales, Marketing, Operations and HR workflows.

Yes. Our application maintenance and support can include monitoring, issue resolution, security updates, cloud performance optimisation, backups, infrastructure changes and continued feature development.
