Application Services (often used instead of application management services or application services management) are a pool of services such as load balancing, application performance monitoring, application acceleration, autoscaling, micro‑segmentation, service proxy and service discovery needed to optimally deploy, run and improve applications.
The process of configuring, monitoring, optimizing and orchestrating different app services is known as application services management. Today, organizations with their own data centers or which use the public cloud, handle applications services management. In the early days of online adoption, application service providers (or ASPs) were companies which would deliver applications to end users for a fixed cost. This single tenant, hosted model was largely replaced by the advent of the Software-as-a-Service (SaaS) delivery model which was multi-tenant and on-demand. Cloud App Services are a wide range of specific application services for applications deployed in cloud-based resources. Services such as load balancing, application firewalling and service discovery can be achieved for applications running in private, public, hybrid or multi-cloud environments.
