Overview
What Is Cloud Architecture, Reliability and Resilience?
Cloud architecture designed for availability, scale and recovery, with the monitoring to keep it that way.
The Need
- Outages or slowdowns that affect customers and staff
- Cloud environments that grew without a clear design
- Recovery plans that have not been tested
The Approach
- Review architecture against availability and recovery needs
- Design for redundancy, scaling and failure
- Add monitoring and test recovery regularly
Assumptions and Dependencies
- Agreed availability and recovery targets for key services
- Access to cloud accounts and architecture documentation
- Owners for each application and environment

Fit and Dependencies
- Works best when availability targets are agreed with the business
- Results depend on acting on design findings and testing recovery
What It Includes
What the Solution Includes
The main elements and the role each plays. The exact scope is agreed for each engagement.
How It Works
How It Works
A cycle of design, testing and improvement, so resilience keeps pace with change.
Assess
Review architecture, past incidents, monitoring and recovery arrangements.
Design
Agree availability targets and the design patterns for each service.
Deploy and Integrate
Apply design changes, monitoring and automation in planned stages.
Validate
Test failover and recovery, and check performance under load.
Operate and Improve
Review incidents and capacity regularly, and improve the design where agreed.

Implementation
Planning a Successful Implementation
Points to review early, so the work is scoped accurately.
- Availability and recovery targets for each service
- Dependencies between applications and data
- Cost of added redundancy against the cost of downtime
- Change windows for architecture changes
- Monitoring tools and on-call processes already in place
- Engagement model and ongoing support
Measuring Success
How to Measure Success
Example measures, not results achieved by Signisys. Agree a baseline, and keep targets separate from measured results.
Availability
The share of time key services are available.
Recovery Time
How quickly services are restored after a failure.
Incident Frequency
How often incidents affect users.
Response Time
How quickly applications respond at peak load.

FAQs
Frequently Asked Questions
Common questions about cloud reliability and resilience.
What business problem does this solution address?
Cloud services that fail, slow down or cannot recover quickly, often because the environment grew without a resilient design.
How does the solution work?
It reviews the architecture, designs for redundancy and scale, adds monitoring and tests recovery regularly.
Which environments can it support?
Public cloud, in one or more providers, and hybrid environments.
What prerequisites should we assess?
Agreed availability and recovery targets, current architecture, past incidents and monitoring in place.
Which services are available to implement it?
Cloud Computing and Platform Engineering and Consulting and Managed Services, covering assessment, implementation and ongoing improvement where agreed.
How do we know it is working?
Agree a baseline for measures such as availability, recovery time, incident frequency and response time, and track them over time.
