Com a mudança para a cloud, a equipa de operações de TI redesenha o modelo de monitorização da infraestrutura

Descubra como uma abordagem centralizada à monitorização permite que as equipas de TI e de aplicações empresariais acrescentem mais valor às respetivas funções.

O desafio: Adaptação a um modelo de funcionamento na cloud

Nos tempos em que a equipa de Plataformas de Capacidade de Gestão, que faz parte da organização Core Services and Engineering (CSEO) da Microsoft, geria a infraestrutura num ambiente centralizado de monitorização e alertas, o modelo era claro: concebia um serviço independente que as equipas de aplicações empresariais consumia. Depois, a Microsoft migrou para a cloud e o modelo deixou de funcionar.

À medida que a empresa mudava os sistemas e as aplicações internas para o Azure, as equipas de aplicações empresariais criaram as respetivas máquinas virtuais (VMs) e queriam ter controlo total sobre as mesmas, mas a responsabilidade de as monitorizar e gerir ainda era da equipa de Plataformas de Capacidade de Gestão. As tentativas de dividir responsabilidades não resolveram o problema. A equipa de Plataformas de Capacidade de Gestão percebeu que, com a mudança para a cloud, a melhor forma de cumprir a sua missão de capacitar as equipas de desenvolvimento era abandonar o negócio de monitorização diária e promover um modelo de monitorização descentralizado novo.

"The move to Azure redefined the relationship between business app teams and us … It literally broke how we worked, including our accountability model, and we had to redesign our support services to accommodate the new self-service cloud model."

Alterar a cultura de controlo

Initially, the Manageability Platforms team tried creating its own pool of Azure subscriptions for the business app teams to use. They quickly found that were still a bottleneck for teams that wanted to administer things on their own. With automation and self-service capabilities becoming available in Azure Monitor, the Manageability Platforms team saw the opportunity to replace their centralized model and hand over responsibility for monitoring to the business app teams. At the same time, they knew they'd have to drive a challenging cultural shift to overcome resistance.

But first, they had to make sure that the operations part of the new DevOps model was in order. They cleaned up a mess of old alerts from about 100 down to 15 and then created a toolkit on GitHub to help the business app teams monitor their own infrastructure. The toolkit established guardrails that helped Manageability Platforms ease their own discomfort with having to relinquish control over something they'd owned for years. Their final push involved a major, multifaceted communication and training effort across the organization.

"Our KPIs used to be all about alerts, trouble tickets, time to resolution, and so on. Today they're around things like inventory, security patching, compliance, and other components of enterprise manageability."

A monitorização descentralizada capacita ambas as equipas

The transition to a decentralized, self-service approach to enterprise monitoring and reporting wasn't easy, but it was worth the effort. Now, reporting and dashboard tools that are enabled by Azure Monitor and Power BI make it easy for business app teams to monitor any part of their environment. With the ability to quickly tailor their own dashboards and alerts to align with how they build and manage their apps, they configure the monitoring environment that best meets their needs. Instead of providing a day-to-day monitoring service that the development teams consume, today the Manageability Platforms team members have become valued consultants in their partnership with development. Most importantly, they're free to focus on more strategic, forward-looking projects—such as security patching, inventory, and compliance—that bring more value to the business.
