Systems Architecture

Systems Architecture, Administration & Support

Behind every reliable application is a well-designed infrastructure. Whether you are running a single WordPress site on a VPS, orchestrating microservices across Kubernetes clusters, or managing a fleet of IoT devices in the field, the architecture of your systems determines their performance, security, scalability and cost-efficiency.

Digital Tactics brings over a decade of hands-on experience designing, building and managing infrastructure across the full spectrum — from traditional dedicated servers and virtual private servers through to modern cloud-native environments on AWS. We are an AWS Consulting Partner with deep expertise in EC2, Lambda, RDS, S3, CloudFront, ECS and the broader AWS ecosystem. We also work extensively with Docker, Kubernetes, Terraform and Ansible for containerisation and infrastructure-as-code.

Our approach is practical, not theoretical. We understand that most organisations do not start from a green field — they have existing systems, legacy dependencies and real constraints. We meet you where you are, assess what you have, and design a path forward that balances ambition with pragmatism. Whether that means a full cloud migration, a hybrid architecture, or simply hardening and optimising your current setup, we deliver infrastructure that works for your business.

Our Approach

We follow a structured three-phase process that moves from thorough assessment through considered architecture design to reliable ongoing management and support.

Assess

We review your current infrastructure, workloads, costs and pain points to build a complete picture of where you stand

Architect

We design a target architecture with CI/CD pipelines, infrastructure-as-code and a phased migration or implementation plan

Manage

We implement, monitor and maintain your infrastructure with proactive support, patching and capacity management

"Digital Tactics were professional but also very personable and spoke in plain English, a rare thing for IT companies! The project was well formed at concept stage with good qualitative questioning ensuing our requirements and budget were met on time. The communication was excellent throughout development and the software worked perfectly from launch."

Key Deliverables

Every engagement produces documented, reproducible infrastructure that your team can understand, maintain and build upon.

• Infrastructure audit and current-state architecture documentation
• Target architecture design with network, security and scaling specifications
• CI/CD pipeline design and implementation (GitHub Actions, GitLab CI, Jenkins)
• Infrastructure-as-code using Terraform, CloudFormation or Ansible
• Docker containerisation and Kubernetes orchestration setup
• Cloud migration planning and execution with zero-downtime cutover
• Monitoring, alerting and log aggregation configuration
• Managed infrastructure support retainer with SLA (optional)

From a one-off architecture review to a fully managed infrastructure partnership, we provide the expertise and reliability that your platforms demand.
