Expertise · LughSoftware
Designed to operate across regions
Your users, partners or activities span several territories. Your application needs to account for that distribution, its data and the conditions under which service must continue.
LughSoftware helps you define an architecture suited to these needs and prepare for its operation.

Start with user needs and recovery objectives
Where are your users? Which journeys must remain accessible? How much interruption is acceptable, and how much recent data could be lost during an incident? These questions frame the technical choices.
Recovery strategies range from restoring backups to deployments across several active regions. Their different costs and levels of complexity need to be assessed against business objectives. AWS reference
Four connected areas to address
Service distribution
Discovery identifies the components needed in each region, shared dependencies and how users will be routed. These choices must also account for the capabilities of the team operating the system.
Data ownership
For each type of data, define its authoritative source, who can change it and how other components receive updates. Propagation delays and potential conflicts must be compatible with business rules, particularly for stock, reservations or financial transactions.
Continuity of user journeys
A standby region is useful only if the elements needed for each journey are available: application, authentication, data, configuration and external services. The plan must identify dependencies that could limit recovery.
Day-to-day operations
Monitoring, alerts, deployments and access management are part of the operating scope. Procedures should state who decides to fail over, what needs checking and how to return to a stable situation.
Prepare and verify recovery
We propose incident scenarios based on your critical journeys and define the associated checks. Recovery objectives are assessed through exercises agreed with the people responsible for the service.
Data replication alone does not replace backups: mistakes or corruption can also be replicated. Restoration scenarios must therefore be included in the recovery arrangements. AWS reference
Decisions your organisation can understand
The work may produce an architecture diagram, a data-flow map, recovery objectives, a failover procedure and an exercise plan. Deliverables, responsibilities and operating resources are agreed during discovery.
Data location and access are reviewed with the relevant people in your organisation. Deploying an application in a given region does not by itself establish all the conditions under which its data is processed.
Build with your teams
The technical lead supports architecture decisions. Your Lugher facilitates communication between your organisation and engineers in India, helping everyone understand operational constraints and business priorities.
Availability levels, support coverage and response times depend on the selected operating arrangements and agreed commitments.
