For large-scale distributed systems, it is crucial to efficiently diagnose the root causes of
incidents to maintain high system availability. The recent development of microservice …

In this paper, we describe Roots-a system for automatically identifying the" root cause" of
performance anomalies in web applications deployed in Platform-as-a-Service (PaaS) …

Although academic and industry experts are now advocating for going from large-
centralized Cloud Computing infrastructures to smaller ones massively distributed at the …

Abstract Service composition is a key concept of Service‐Oriented Architecture that allows
for combining loosely coupled services that are offered and operated by different service …

We present Roots, a full-stack monitoring and analysis system for performance anomaly
detection and bottleneck identification in cloud platform-as-a-service (PaaS) systems. Roots …

Cloud computing services are used to fulfill user requests, often expressed in the form of
tasks and their execution in such environments requires efficient scheduling strategies that …

From the cloud provider perspective, applications are usually black boxes hosted on Virtual
Machines. Managing these black boxes without knowing anything about the features of the …

Cloud Service Provider (CSP) offers a wide variety of scalable, flexible, and cost-efficient
services to users on demand and pay-per-utilization basis. However, vast diversity in …

In this paper, we present TREX, a novel tenant-driven network traffic extraction platform for
SDN-based cloud environments. With TREX, tenants can define templates that consist of …

Cloud computing is a suitable solution for professionals, companies, and institutions that
need to have access to computational resources on demand. Clouds rely on proper …
