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...
Scalability is an important requirement in the development and the operation of applications in a cloud environment. To handling heavy concurrency in the input load, many design-related and operational factors should be considered. The microservice architecture patterns provide better means to increase the scalability than traditional software architecture patterns. However, certain aspects of applications...
In today's open market, e-commerce has developed its strategy to process various business applications. There applications are developed with the platforms like Magento, Zen Cart, Prestashop, Spree etc., to run a successful online store. These are also used for customer e-commerce apps and require a scalable database for storing the data. The NoSQL database provides an efficient storage access and...
Cloud computing and Network Function Virtualization (NFV) are emerging as key technologies to overcome the challenges facing 4G and beyond mobile systems. Over the last few years, Platform-as-a-Service (PaaS) has gained momentum and has become more widely adopted throughout IT enterprises. It simplifies the applications provisioning and accelerates time-to-market while lowering costs. Telco can leverage...
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...
Decreasing cost and increasing capabilities of instrumentation, networks and data repositories have pervaded the industrial automation and power markets and opened the door for large scale collection and analysis of data. There are a variety of technology stacks that can be applied to these types of activities. However, no single infrastructure or architecture fits all the scenarios. With limited...
The development and wide application of the internet technology produces a large amount of data, in order to storage and manage these massive data, NoSQL database technology comes into beings and develops rapidly, many manufacturers have introduced many different NoSQL storage solutions. In this context, the paper carries out the work about the testing method of the performance of NoSQL database....
In order to design distributed business applications or services, the common practice consists in setting up a multi-tier architecture on top of a relational database. Due to the recent evolution of the needs in terms of scalability and availability in cloud environments, the design of the data access layer got significantly more complicated because of the trade-off decisions between consistency,...
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...
Significant requirements for a large digital preservation system are the system scalability, its ability to store and service heterogeneous digital holdings, and the evolvability over time of both the technologies comprising the system and the data formats in its storage. The use of information technology by the government, business corporations, academic institutions, and the general public results...
Enterprise Service-Oriented Architecture (ESOA) style defines the principles and guidelines for designing and implementing complex business processes and systems. This paper classifies ESOA style to six substyles based on a domain model of service-oriented enterprise and an abstract model we proposed. The definition of each style is provided. A comparison of parts and constraints of five basic ESOA...
In the context of Enterprise Application Integration individual tasks have typically been implemented using specialized EAI-vendor technology based on messaging, and quite often customer-specific implementations. Those implementations prominently exploit the Pipes-and-Filters architecture. This implementation approach is in conflict with the flow technology that is a cornerstone of the Service-Oriented...
Aiming at the requirements in the process of building a SOA application system, such as dynamic service deployment, service finding and reference, the demand for adaptability to change and system scalability, this paper introduces the characteristics and drawbacks of service-oriented architecture, describes the theory about OSGi and its advantages. Through the combination of SOA with OSGi, a dynamic...
This paper introduces a software as a service (SaaS) application which is designed and delivered in high level maturity model. In order to realize the configurability, metadata is used to define all the variability points of the application. Meanwhile, JMX is used to manage the metadata so that changed metadata can be hot deployed immediately during runtime. Scalability is discussed both in application...
Multi-tenant business support system (BSS) is a form of Software as a Service, which can provide business support services for service carriers at a low cost by leveraging economy of scale. In this paper, we present the architecture of multi-tenant BSS and discuss briefly the approach to achieve configurability, security and scalability of the architecture. Focusing on scalability of data, we propose...
System performance and scalability issues often have their roots in architectural and design choices that are made early in the software life cycle. Because he must communicate with developers, designers, product managers, business stake holders, application domain experts, testers, and requirements engineers, the software architect is uniquely placed to play a leadership role in linking performance...
This paper is about a software architecture, named WCAM (watcher, controller, action, and model), which reduces the complexity of context-aware systems by decoupling of concerns. We first introduce general requirements of context-aware systems. Next, we present our architecture pattern, WCAM. Watcher perceives external environment, and controller manages the cooperation between watcher and model....
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...
