Overview
ALYac SDP defines the standard procedures for deploying ALYac, minimizing release risk and ensuring seamless updates for end users. It covers development, QA, and operations across the full deployment lifecycle.
Deployment Planning
Selecting the appropriate deployment model and release schedule for each build.
Pre-Deployment
Multi-layered validation across functionality, security, compatibility, and compliance.
Deploy & Operate
Staged execution, real-time monitoring, incident response, and rollback procedures.
Deployment Strategy
ALYac follows three structured deployment models. Every model operates under the assumption that an immediate rollback is possible at any stage.
Staged Rollout
Gradual deployment to a subset of users before full deployment. Telemetry and crash rates are observed at each stage; if anomalies are detected, the rollout does not proceed to the next phase.
Maintenance Channel Deployment
A separate channel for customers who prioritize operational stability and predictability over the latest features. Only validated stable versions are delivered through this channel.
Canary Deployment
Deployment to a small group of users before full release, enabling early detection of regressions and conflicts. The lightest and fastest mechanism for identifying release risks.
Release Schedule
| Release Type | Cadence | Description |
|---|---|---|
| Major Update Major | Annually | Major releases introducing new services or architectural changes. |
| Minor Update Minor | Semi-annually | Regular releases with feature improvements and scheduled security patches. |
| Emergency Hotfix Hotfix | As needed (up to once per month) | Urgent response to zero-day vulnerabilities or critical defects. |
Pre-Deployment Process
Functional and security validations are treated with equal weight. Static and dynamic analyses are performed in parallel.
- UNITUnit TestingVerification of code correctness
- INTEGIntegration TestingEnsuring interactions between components
- SYSTEMSystem TestingValidation of overall functionality
- UATUser Acceptance TestingVerification by a subset of end users
- SCRSecure Coding ReviewSQL Injection, XSS, Buffer Overflow, etc.
- SASTStatic AnalysisIdentifying security flaws using static tools
- DASTDynamic AnalysisVulnerability testing in a runtime environment
- SIGNCode Signing & ComplianceAuthenticity verification and regulatory compliance
Deployment Execution
Deployment proceeds through four sequential stages. Each stage has explicit pass-through criteria; if any anomaly arises, the process immediately transitions to the rollback procedure.
Backup
All release builds are backed up before deployment to guarantee recovery capability.
Version Management
Final verification of release version, signature, and metadata.
Deployment
Updates are delivered according to the selected deployment model.
Monitoring
Real-time tracking of errors and failures with automatic alerts on threshold breaches.
Post-Deployment Management
Monitoring begins in earnest the moment deployment concludes. Collected data is fed back into the next release cycle as input for continuous improvement.
Monitoring & Logging
- Continuous collection of logs and telemetry
- Automated crash report aggregation
- Active user feedback channels
Incident Response
- Immediate classification and prioritization
- Rapid patch line for critical issues
- Rollback decision triggers in operation
Performance Tuning
- Analysis of system resource usage
- Hotfix release on performance regression
- Improvement items fed into next cycle
