Application performance management continues to be so hard because applications are becoming increasingly complex, relying on multiple third-party components and services that are all added to the already-complicated modern application delivery chain that includes the applications and the backend IT infrastructure that supports them —plus all the software, middleware and extended infrastructure required for performance. This modern application stack, or AppStack, is often managed the old-fashioned way — in silos, without holistic visibility of the entire stack at once.
When the cloud gets added to the mix, none of the traditional AppStack goes away, but it’s no longer managed by the hosting agency in an on-premises datacenter. Nevertheless, IT is still accountable for application performance. So, what can application administrator do to ensure consistent top performance in a hybrid cloud environment? Here are a few things to consider:
Add a step. In a hybrid cloud system, instead of trying to pinpoint where and what the problem is, the first step is quickly and definitively determining who owns the problem -- IT or the cloud vendor.
Get involved in the development phase. Cloud monitoring and management decisions need to be made when the hybrid cloud environment is being created. Don’t get stuck trying to manage applications that weren’t designed for the cloud. By getting involved in the development phase, administrators can ensure they have control over application performance.
Manage cloud and on-premises performance data to determine the root of the application issue. IT needs to determine whether the application performance issue is with the software or the configuration. To achieve full visibility into the performance issue, a monitoring system must be in place to definitively determine where the problem lies.
Plan for the worst-case scenario to prevent it from happening. Early on, administrators should think through and plan for the worst-case scenarios in a hybrid cloud environment to spot problems before they arise and to be prepared should they actually occur. Make sure, for example, that critical systems can failover to standby systems and data is backed-up and archived according to agency policies.
And let’s not forget the network’s role. Application delivery is only as good as the network, and cloud or hybrid apps need to traverse a path across your network to the cloud provider and back. Visibility of the network path can assist in troubleshooting.
Every technological shift comes with a unique set of complexities and challenges – and the need for new understanding. The hybrid cloud is no different. However, gaining visibility into application performance can help agencies reap the benefits of hybrid cloud environments and ensure application performance remains consistently strong.
