In recent years, many companies have begun moving critical applications to hyperscale cloud providers as a way to save money, improve reliability, and take advantage of the security services offered by the large cloud providers. The cloud frees users from operating their own infrastructure, allows them to pay for only the resources they use, and gives them a huge team of cloud experts to support their applications.\nEven with these advantages, moving mission critical applications to hyperscale cloud services can be an anxiety-inducing process, as organizations often don't have full visibility to monitor these apps, the network, and their performance.\nIn many cases, this means companies worry about missing app dependencies in the process. They don\u2019t have hard data on how these applications will perform in the cloud \u2013 and whether the network at the cloud provider and the network between the client and the cloud provider are up to the task.\nWhile cloud providers offer their own monitoring tools, organizations moving important applications to the cloud should consider doing their own monitoring. One modern term for this type of monitoring is \u201cvisibility and performance management,\u201d or VPM, while some also call it \u201cobservability.\u201d\nA new way to look at monitoring\nCompanies have always had to monitor systems to see if they\u2019re working or failing. But as complexity has increased, there\u2019s a greater need for observability. And while moving applications to the cloud has many benefits, it does add complexity to computing systems.\nWhen a company has a complex system and something fails, it can be difficult to track down the cause. It was relatively easy to do this when systems were monolithic. In addition, moving to the cloud adds a new, outside computing system to the mix as well as new networks, which can, at times, run more slowly than expected. As systems become more complex, they need more efficient ways to observe what\u2019s going on.\nA VPM tool can provide visibility into the apps,\u00a0allow users to proactively manage their performance, automatically identify potential problems, and resolve network and application challenges quickly and securely.\nReducing mean time to repair\nVPM addresses the so-called mean time to innocence, the time it takes to prove that the network, the application, or the cloud provider is not to blame for an application performance problem. It allows companies to identify the particular domain that\u2019s causing the problem.\nAs a result, VPM can reduce the mean time to repair. Companies can find what\u2019s causing the problem, fix it as soon as possible, and make sure it doesn\u2019t happen again. This is particularly important when an organization wants to securely move a mission-critical application to a hyperscale cloud provider.\nVPM helps companies understand and benchmark the normal performance of an app before moving it. It will not only monitor an app at a specific time, but also help companies understand the normal performance over time, so it gives users data-driven performance monitoring.\nFor example, users sometimes complain that an app\u2019s performance has suffered after it has been moved to the cloud. VPM can show users if that\u2019s actually the case, or if the performance lag is just a perception. It can also tell companies if the move to the cloud actually improved performance as expected, providing users with both before-and-after data.\nUnderstanding dependencies\nMost modern VPM tools can also visualize the topography of an app and its dependencies. It allows users to see how apps and systems are connected and see paths through the network. If a company is moving a complex application, it can see the topography and its dependencies, so that it doesn\u2019t miss a dependency in the move. As noted above, missing a dependency is one of the biggest fears that IT teams have when moving these complex applications to the cloud.\nThis all leads to a more secure and reliable move of complex and mission-critical apps to a hyperscale cloud provider.\nVPM and related tools allow companies to move apps to the cloud and ensure that they perform at least as well as they did on premises. If there are problems, users have the visibility they need to reduce mean time to innocence and mean time to resolution.\nLearn more about how VPM reduces risk when companies need to move their mission-critical applications.
