Engineering capabilities
- VPC and subnet design
- Instance sizing and placement
- Managed service selection
- Cost-aware architecture
Cloud & Virtualization
AWS
Workload placement, network boundaries and access control on AWS, sized to measured demand.
Security & hardening
- IAM least privilege
- Security group discipline
- Logging and audit trails
AWS landing zone reference
Accounts, network boundaries and identity are laid out before workloads land, so growth does not turn into an unreviewable sprawl of resources.
-
01
Account & identity
- Organizations / OUs
- IAM roles & SSO
- Guardrail policies
Separate accounts for production and non-production; humans use roles, not long-lived keys.
-
02
Edge
- Route 53
- CloudFront / WAF
- Application Load Balancer
TLS terminated at the edge, rate limiting and managed rule groups applied before traffic reaches compute.
-
03
Network
- VPC
- Public subnets
- Private subnets
- NAT / VPC endpoints
Only load balancers and bastions are public; everything else egresses through NAT or private endpoints.
-
04
Compute & data
- EC2 / Auto Scaling
- ECS or EKS
- RDS
- S3
Instances sized from measured load, storage encrypted with KMS, multi-AZ where the RTO requires it.
-
05
Operations
- CloudWatch
- CloudTrail
- AWS Backup
- Budgets & alarms
Audit trail retained centrally; backups and cost alerts configured at build time, not after the first surprise.
Frequently asked questions
How do you keep AWS costs predictable?
Right-sizing from measured utilisation, scheduled shutdown of non-production, S3 lifecycle rules, and budget alarms wired to email before spend becomes a monthly discovery.
Do we need multi-AZ or multi-region?
Multi-AZ is the default for anything with a real RTO. Multi-region is only worth its complexity and cost when the business genuinely cannot tolerate a regional outage.
How is access controlled?
Federated sign-in with MFA, permissions granted through roles scoped per environment, and no shared root or static access keys in application code.
Can you migrate our existing servers to AWS?
Yes. Discovery maps dependencies and licensing, replication runs ahead of the window, and cutover follows a rehearsed runbook with documented rollback.
