En primer lugar, sugiero no aplicar las actualizaciones de software en el ambiente de producción. Las actualizaciones se deben verificar en un ambiente de prueba. Una vez verificada su calidad funcional, proceder su aplicación al ambiente de producción.

We can simply plan upgrades during low-activity periods and conduct them in a controlled testing environment before live deployment. Also, such deployments should be communicated to internal and external stakeholders in advance to set expectations. One last thing to mention here is to set a rollback plan to allow a swift action if unexpected issues arise, ensuring continuity in operations.

System updates are essential for staying ahead with innovations, but they can be challenging. To keep workflows smooth during tech transitions, I rely on a few key strategies:Creating testing environments to validate new versions before implementation; Strict dependency management to minimize conflicts; Automating CI/CD processes to efficiently validate builds; Careful planning and communication with the team to reduce business impact; Providing training and documentation to ease adaptation to new features; With these practices, I stay focused on both innovation and productivity!

Focus on thorough planning, testing, and clear communication. Begin with a phased rollout, scheduling upgrades during low-activity periods. Ensure an impact analysis is conducted including on upstream and downstream systems. Use sandbox environments and perform rigorous testing, including User Acceptance and Regression Testing, to catch issues early. Inform users in advance and offer training if the upgrade introduces changes. Always back up systems and have rollback plans ready to revert if needed. Finally, monitor performance closely during the transition and provide dedicated support to resolve any issues immediately.

1) Identify the key activities/outputs of the business. 2) Identify all of the key systems and their dependencies required for the key activities. 3) Assess the impact of the key systems going down. Factor in different variables such as the time the system would be taken offline (there should be a lower impact of taking a system offline outside of key business hours compared to busy periods). 4) Identify any and all workarounds. 5) Establish a risk threshold and what the business considers to be a state of intolerable harm. This will define what you can and cant do. 6) Based on the findings of the prior steps, create 2-3 plans/options, risk assess each option and decide on the option best suited for the business.

Thorough Planning: Map out every step, from downtime windows to rollback strategies. Effective Communication: Keep everyone informed, from users to management. Test Thoroughly: Simulate the upgrade in a controlled environment to catch potential issues. Phased Rollout: If possible, upgrade systems in stages to reduce overall risk. Robust Backup: Ensure you have reliable backups to restore in case of unexpected problems. Dedicated Support Team: Have a team ready to address any issues that arise during and after the upgrade.

Follow these steps : 1. Assess impact, define scope and timeline. 2. Ensure full backups and a rollback plan in case of issues. 3. Use a staging environment and conduct user acceptance testing. 4. Schedule the upgrade during low-activity times and notify users. 5. Execute old and new versions together for a smooth transition. 6. Track performance and have support ready for immediate issues. 7. Gather feedback for improvements and document lessons learned.

Toda actualización incluso de seguridad, si puede afectar el funcionamiento del sistema, debe ser testeada en un ambiente de QA. Se debe tener un plan de despliegue, analizando si puede ser escalado, el horario de menor impacto, la validación tras la implementación de la actualización y en el peor escenario tener el rollback también testeado y listo para aplicarse.

Automatizo as atualizações,(Inspector/Lambda, Uyuni) mas as reinicializações necessárias para carregar bibliotecas essenciais ficam pendentes para evitar qualquer impacto nas operações. Uso estratégias como autoscaling para manter redundância durante o processo e, em ambientes de contêineres Docker ou Kubernetes, faço o drain das cargas, preservando a continuidade dos serviços enquanto aplico os patches. Também uso blue-green deployments e reboots programados em horários de baixo tráfego, garantindo que as atualizações não interfiram no uptime. Dessa forma, conseguimos manter o ambiente atualizado e operando sem grandes interrupções.

Schedule upgrades during off-hours or slower periods to reduce impact. Communicate with your team about the timeline and what to expect. Have a backup plan. So you can roll back changes if needed. Test in a staging environment before full deployment. Have support on standby for any issues.
