A current value of a Key Performance Indicator (KPI) of an executing cloud service instance of a cloud application is detected. A determination is made as to whether the current value of the KPI is unacceptable (e.g., either it is outside of an acceptable range or is within an adaptation region). If the current value of the KPI is unacceptable, a first application programming interface (API) is invoked to request a cloud service instance monitor to adapt the cloud service instance to operate within an acceptable KPI range. If the cloud service instance monitor was unsuccessful, the unacceptable KPI is escalated to the cloud service monitor for the type of the cloud service instance. If the cloud service monitor is unsuccessful, the unacceptable KPI is escalated to the application monitor. ## Claims ### Claim 1 A system for dynamically adapting a cloud application, the system comprising: a key performance indicator (KPI) detector to detect a current value of a KPI of an executing cloud service instance of a cloud application, the cloud application hosted by a Platform as a Service (PaaS) provider, the KPI corresponding to a service level agreement (SLA) between a provider of the cloud application and a user of the cloud application, the cloud service instance having a service type;

and a third KPI adaptor to invoke, upon a determination that the cloud service monitor was not successful, a third API provided by the PaaS provider to request an application monitor for the cloud application to adapt the cloud application to operate within the acceptable range. ### Claim 4 (depends on 3) The system of claim 3, wherein at least one of the cloud service monitor and the application monitor is provided to the cloud application by the PaaS provider. ### Claim 5 (depends on 1) The system of claim 1, wherein the SLA is represented in a machine-readable format. ### Claim 6 (depends on 5) The system of claim 5, wherein the machine-readable format conforms to the Open Cloud Computing Interface (OCCI) SLA specification. ### Claim 7 (depends on 3) The system of claim 3, wherein the cloud service instance monitor is provided in an Application Support Toolkit (AST) by the PaaS provider. ### Claim 8 (depends on 7) The system of claim 7, wherein the AST includes a library of executable code, which when executed, causes the system to facilitate communication, via a fourth API provided by the PaaS provider, between the cloud service instance and a platform provided by the PaaS provider. ### Claim 9 (depends on 1) The system of claim 1, wherein the cloud service instance and the cloud service instance monitor are to execute within a virtual machine of a platform provided by the PaaS provider. ### Claim 10 (depends on 9) The system of claim 9, wherein the adaption includes at least one of the cloud service monitor and the application monitor to initialize an additional virtual machine within the platform to execute a new cloud service instance. ### Claim 11 (depends on 9) The system of claim 9, wherein the adaption includes at least one of the cloud service monitor and the application monitor to decommission a virtual machine within the platform; and wherein the cloud service instance, whose current KPI value is outside of the acceptable range, had executed within the virtual machine to be decommissioned. ### Claim 12 (depends on 1) The system of claim 1, wherein to determine whether the current value of the KPI is outside of an acceptable range includes to determine whether the current value of the KPI is within a KPI adaptation range. ### Claim 13 A method of dynamically adapting a cloud application, the method comprising: detecting a current value of a key performance indicator (KPI) of an executing cloud service instance of a cloud application, the cloud application hosted by a Platform as a Service (PaaS) provider, the KPI corresponding to a service level agreement (SLA) between a provider of the cloud application and a user of the cloud application, the cloud service instance having a service type;
