Progressive delivery is a modification of continuous delivery that allows developers to release new features to users in a gradual, controlled fashion. It does this in two ways. Firstly, by using feature flags to turn specific features ‘on’ or ‘off’ in production, based on certain conditions, such as specific subsets of users. This lets developers deploy rapidly to production and perform testing there before turning a feature on.

At one particular time, a developer would spend a few months building a new feature. Then they’d go through the tedious soul-crushing effort of “integration.” That is, merging their changes into an upstream code repository, which had inevitably changed since they started their work. This task of Integration would often introduce bugs and, in some cases, might even be impossible or irrelevant, leading to months of lost work.

This article explores the challenges associated with debugging Celery applications and demonstrates how Lightrun’s non-breaking debugging mechanisms simplify the process by enabling real-time debugging in production without changing a single line of code.

Code instrumentation is closely tied to debugging. Ask one of the experienced developers and they will swear by it for their day-to-day debugging needs. With modest beginnings in the form of print statements that label program execution checkpoints, present-day developers employ a host of advanced techniques for code instrumentation. When carried out in the right way, it improves developer productivity and also reduces the number of intermediate build/deployment cycles for every bug fix.

Cloud native is the de facto standard approach to deploying software applications today. It is optimized for a cloud computing environment, fosters better structuring and management of software deployments. Unfortunately, the cloud native approach also poses additional challenges in code instrumentation that are detrimental to developer productivity.

IOException is the most generic exception in a large group of Java exceptions that express input/output and networking errors in Java applications.

Lightrun enhances its enterprise-grade platform with the addition of RBAC support to ensure that only authorized users have access to sensitive information and resources as they troubleshoot their live applications. By using Lightrun’s RBAC solution, organizations can create a centralized system for managing user permissions and access rights, making it easier to enforce security policies and prevent security breaches.
