No Update Policy vs Rolling Updates
Developers should adopt a No Update Policy when maintaining systems that require extreme reliability, such as medical devices, industrial control systems, or financial transaction processors, where any change could lead to catastrophic failures or security breaches meets developers should use rolling updates when deploying updates to production environments that require high availability, such as web applications, apis, or microservices, to avoid service interruptions and reduce risk. Here's our take.
No Update Policy
Developers should adopt a No Update Policy when maintaining systems that require extreme reliability, such as medical devices, industrial control systems, or financial transaction processors, where any change could lead to catastrophic failures or security breaches
No Update Policy
Nice PickDevelopers should adopt a No Update Policy when maintaining systems that require extreme reliability, such as medical devices, industrial control systems, or financial transaction processors, where any change could lead to catastrophic failures or security breaches
Pros
- +It is also useful for legacy applications that are no longer actively developed but must remain operational, or in environments with strict regulatory compliance that mandates unchanged software versions
- +Related to: software-maintenance, risk-management
Cons
- -Specific tradeoffs depend on your use case
Rolling Updates
Developers should use rolling updates when deploying updates to production environments that require high availability, such as web applications, APIs, or microservices, to avoid service interruptions and reduce risk
Pros
- +It is particularly valuable in scenarios where zero-downtime deployments are critical, such as e-commerce sites or real-time services, as it allows for gradual testing and rollback if issues arise
- +Related to: kubernetes, docker
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use No Update Policy if: You want it is also useful for legacy applications that are no longer actively developed but must remain operational, or in environments with strict regulatory compliance that mandates unchanged software versions and can live with specific tradeoffs depend on your use case.
Use Rolling Updates if: You prioritize it is particularly valuable in scenarios where zero-downtime deployments are critical, such as e-commerce sites or real-time services, as it allows for gradual testing and rollback if issues arise over what No Update Policy offers.
