The growth of cloud-based services and applications has made controlling business IT more difficult . There are now more devices , applications and networks than ever before . Bandwidth becomes an issue as each application also uses additional micro-services . Visibility is also a problem – many applications are hosted in different public , private and hybrid cloud infrastructures using various types of connectivity – public internet or a private VPN / WAN , for example . In these diverse environments , it ’ s not unusual for data to always use a different network path to reach the end-user . This means that the IT department has to identify , analyse and solve problems in a diverse , ever changing environment . Having the right tools in place will enable CIOs to locate and understand network performance problems , optimise infrastructure and application performance , and increase network efficiency . Only when they achieve visibility , optimisation , and control across hybrid clouds and networks can CIOs ensure that on-premise , cloud , and SaaS applications perform to the service-level agreements determined by the business .
