What is Retry Logic?
Retry Logic automatically re-attempts failed prediction requests with exponential backoff to handle transient failures. Proper implementation balances reliability against cascading load and prevents retry storms.
This glossary term is currently being developed. Detailed content covering implementation strategies, best practices, and operational considerations will be added soon. For immediate assistance with AI implementation and operations, please contact Pertama Partners for advisory services.
Proper retry logic handles the 60-70% of transient failures in ML serving that resolve on the second or third attempt. Without retries, these transient issues become visible errors that degrade user experience. With poorly configured retries, recovery from outages is delayed by retry storms that amplify load. Companies with well-implemented retry logic experience 50% fewer user-visible errors while maintaining fast recovery from outages. Retry configuration takes hours to implement correctly and prevents significant user impact.
- Exponential backoff strategy

- Idempotency requirements
- Jitter to prevent thundering herd
- Use exponential backoff with jitter to prevent synchronized retry storms from multiple clients hitting the service simultaneously
- Coordinate retry budgets between client and server layers to prevent retry amplification where retries at each layer multiply total attempts

Common Questions
How does this apply to enterprise AI systems?
This concept is essential for scaling AI operations in enterprise environments, ensuring reliability and maintainability.
What are the implementation requirements?
Implementation requires appropriate tooling, infrastructure setup, team training, and governance processes.
More Questions
Success metrics include system uptime, model performance stability, deployment velocity, and operational cost efficiency.
Use exponential backoff starting at 100ms with a multiplier of 2, capping at 5 seconds. Set maximum retry count to 3 for real-time predictions to limit total latency. Add jitter of 0-50% of the backoff interval to prevent retry storms when multiple clients fail simultaneously. Only retry on transient errors like timeouts, 503s, and connection resets. Never retry on validation errors (400s) or authentication failures (401/403) since these won't resolve with retries. Log retry attempts for monitoring.
Client-side retries happen at the API consumer and handle network-level failures and server unavailability. Server-side retries happen within the ML service and handle internal failures like GPU memory errors or feature store timeouts. Both are needed but serve different purposes. Coordinate retry budgets between layers to prevent retry amplification where 3 client retries each triggering 3 server retries produce 9 total attempts from one original request. Set a total retry budget across all layers.
Implement circuit breakers that stop retrying after detecting sustained failure. Set concurrent retry limits to prevent retry storms that overwhelm recovering services. Use deadlines rather than retry counts so total request duration is bounded. Monitor retry rates as a health signal since increasing retries indicate systemic issues. During outages, retries can generate 2-5x the normal load on already struggling systems. Implement client-side backpressure that reduces request rates when retry rates increase.

AI Adoption Metrics are the key performance indicators used to measure how effectively an organisation is integrating AI into its operations, workflows, and decision-making processes. They go beyond simple usage statistics to assess whether AI deployments are delivering real business value and being embraced by the workforce.
AI Training Data Management is the set of processes and practices for collecting, curating, labelling, storing, and maintaining the data used to train and improve AI models. It ensures that AI systems learn from accurate, representative, and ethically sourced data, directly determining the quality and reliability of AI outputs.
AI Model Lifecycle Management is the end-to-end practice of governing AI models from initial development through deployment, monitoring, updating, and eventual retirement. It ensures that AI models remain accurate, compliant, and aligned with business needs throughout their operational life, not just at the point of initial deployment.
AI Scaling is the process of expanding AI capabilities from initial pilot projects or single-team deployments to enterprise-wide adoption across multiple functions, markets, and use cases. It addresses the technical, organisational, and cultural challenges that arise when moving AI from proof-of-concept success to broad operational impact.
An AI Center of Gravity is the organisational unit, team, or function that serves as the primary driving force for AI adoption and coordination across a company. It concentrates AI expertise, sets standards, manages shared resources, and ensures that AI initiatives align with business strategy rather than emerging in uncoordinated silos.
