クラウドへの移行に伴い、IT 運用チームがインフラストラクチャ監視モデルを再設計

監視への分散型アプローチの採用により、IT チームとビジネス アプリ チームの両方がそれぞれの役割により多くの価値をもたらすことができます。

課題: クラウド運用モデルへの適応

Microsoft Core Services and Engineering (CSEO) に属する Manageability Platforms チームが、一元化された監視およびアラート環境でインフラストラクチャを管理していたときには、モデルは明確でした。チームは、ビジネス アプリ チームが使用する自己完結型サービスを提供していました。その後、Microsoft がクラウドに移行し、このモデルは機能しなくなりました。

会社が内部システムとアプリを Azure に移行したため、独自の仮想マシン (VM) を作成したビジネス アプリ チームは、それらを完全に制御することを望んでいましたが、Manageability Platforms チームがそれらの VM の監視と管理に対して引き続き責任を負っていました。責任の分担を試みましたが、問題は解決しませんでした。Manageability Platforms チームは、クラウドへの移行に伴って、ビジネスの日々の監視から脱却し、新しい分散型監視モデルを支持することが、開発チームの希望を実現するという使命を果たす最良の方法であることに気付きました。

"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."

制御の文化の変革

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."

分散型の監視によって両方のチームを強化

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.
