Microservice architectures provide small services that may be deployed and scaled independently of each other, and may employ different middleware stacks for their implementation. Microservice architectures intend to overcome the shortcomings of monolithic architectures where all of the application's logic and data are managed in one deployable unit. We present how the properties of microservice architectures...
Network function virtualization (NFV) is a promising solution for cost reduction, service agility, and scalability to cope with the dynamic changes of traffic volume and business requirements. In the NFV framework, management and orchestration framework (MANO) plays an important roles in the automated provisioning, configuration, lifecycle management, and high availability of virtual network functions...
A key feature of Cloud computing is its agility and flexibility to support the scalability needs of business solutions. Currently, the agility is only limited to the scalability of the compute, memory and storage. To improve an application's agility, we need to monitor & measure solution level metrics and associate the performance of the metrics to the business agility needs of the solution...
The growth of network scale and business diversification makes network management complexity increase dramatically, and the network running status is difficult to control. With the help of network management system that can effectively manage the entire network, so that the network is stable, secure, efficient working. But the prominent problems in network management system is that network equipment...
As a macro complex systematic engineering, the Digital Ocean project is an ongoing task in china. The mission of the Digital Ocean is to build an interactive network information system based on a three-dimensional globe. The Digital Ocean can help provide integrated information on historical, current and future states of ocean and coastal zone. This paper addresses the architecture of Digital Ocean,...
Collecting data on user activities is one of the fundamental middleware services in Web-enabled systems. The collected data is analyzed and used by various high-level services, like user profiling, accounting, security auditing, and system health monitoring. In this paper, we present architecture and performance evaluation of usage tracking components for service-oriented middleware systems. Presented...
We developed a quality of service (QoS) management system to support service level management (SLM) for global enterprise services. The QoS management system is integrated with one of our enterprise services in a preproduction system, an identical system as the production system but in a test environment. Lab experiments showed that our integrated solution helps global enterprise services to better...
