With event, incident and problem management, the first thing you have to do is integrate your cloud environment, alerting flow into your service management toolset, either through ServiceNow or another platform. The human processes initially stay the same: an event gets raised and goes into the service desk; if there is an incident, it gets resolved. While the processes stay the same, how you are going to resolve the issue changes? This will be an incremental change at first, but the increasing adoption of automation will drive the breadth of issues getting resolved without manual intervention. There may be whole classes of incidents/requests, such as the resource scaling removal of temporary resources, which can be handled through automatic rules addressed in the environment. Historically, if you had an outage, human intervention would resolve the issue. Now, you can have issues raised and closed automatically through the adoption of architecture and operational prin- ciples of autoscaling, self-healing and immutable infrastructure. While you can reuse a great deal of your existing service desk capabilities, you will need to plan for the alert integration from your cloud estate and begin to think through the classes of issues that can be streamlined and addressed through automation. Logging and Monitoring While existing logging and monitoring strategies can easily be modified to support data inflow from the cloud, there are a few key differences to consider. First, while you can often reuse existing log aggregation or security incident and event monitoring platforms, you will need to integrate them with cloud provider data flows. Next, you will need to make sure your team understands the key differences between on-premises and cloud architectures. Training IT and security ops personnel on cloud architecture helps ensure they are responding to real signals and not noise based on leg- acy architectural assumptions. Finally, you should begin to consider the storage needs for your logging data. Key ques- tions to consider are where the logging “source of truth” resides (the cloud estate or on-premises), and how that location may change as your adoption of cloud evolves. You will have access to near infinite storage but should not store what you do not need: Your budgets are not infinite! Cloud architectures can allow you to easily create additional enclaves of logging data for various purposes (troubleshooting, forensics, R&D, archiving, etc). While this flexibility is valuable, defining your access and usage pattern will help you manage potential egress charges. Furthermore, developing a data retention strategy based on your regulatory or business requirements for cloud estate logs is important from the outset. Keep it simple to begin with, and leverage cloud provider tools. Conclusion On one level, governance is governance: It is about keeping track of what you have and the processes you follow. But governance in the cloud cannot be just a carbon copy of gover- nance on-premises. It has to be constructed with cloud needs in mind, because it is going to drive the future of your cloud operations. WINTER 2019 | THE DOPPLER | 73
