Description: In this paper we consider the problem of access to content that is located at geographically remote locations and the access delay from the perspective of the end user. We have come to conclusion that the use of CDN networks is especially effective in terms of providing the platform as a cloud service. We investigate the processes of access to static content and loading duration under the conditions of the provisioning of PaaS using the Azure Cloud service. Azure Traffic Manager supports six traffic rout-ing methods that define routing rules for network traffic at different endpoints. The paper focuses on the traffic routing based on priority in Traffic Manager as well as CDN as a technique of decreasing content delivery duration for the clients. After creating the Storage Acount and downloading the relevant content, cached content was accessed from Lviv through the endpoints of Western Europe, Central America, Central India, and eastern Japan. As a result of invastigate, the load time was measured when accessed to the original image located in the Storage account (origin server) located in eastern Australia. The results of the study showed that loading from the endpoints occurred much faster than from the base server, the time of downloading content de-creased by approximately 4 times. The Azure CDN behavior monitoring was conducted. As a result of the research, the channel bandwidth analysis, which provides content delivery, was analyzed. As can be seen bandwidth utilization when accessing content from remote servers increases to 700 kbps. The status codes distribution shows how often certain HTTP response codes arrive over the selected time interval. HTTP replies arrive at the same time intervals and do not depend on the territory from which the request for access to data is sent. Investigation has shown that content should not be cached on a POP or HTTP client. Only in one case at 0.05s the cached version of the requested resource was not found on the POP closest to the client. Content will be requested from both the base server and the base server. Experimental estimations allow to improve the process of design of CDN PaaS on the criterion of delay of the provision of content
