Service Oriented Architecture (SOA) expresses a perspective of software architecture that defines the use of loosely coupled software services to support the requirements of the business processes and software users. In an SOA environment, resources on a network are made available as independent services that can be accessed without knowledge of their underlying platform implementation.
Information technology is at a crucial turning point. Enterprise IT departments are under constant pressure to meet user and application demands, aware that cloud deployments offer an easier and faster alternative but often pinned down by legacy deployment models. The problem stems from the inability of those legacy models to adapt to meet expectations for rapid provisioning, continuous delivery, and consistent performance across multiple environments. Read this whitepaper to learn more about the evolution of application delivery and the services your enterprise can utilize to successfully manage the increased pressure on network and application infrastructure.
The application delivery controller has evolved into a key component of the data center architecture, and enterprises should evaluate ADCs based on how they integrate with this architecture and support more-advanced features, such as user and traffic control and monitoring.
Service providers are already virtualizing and distributing applications and storage across the WAN, driving meshed data center architectures. The supporting Data Center Connect infrastructure will only be successful when it delivers cost-effective scale and meets user requirements for reliability and latency.
This evolution will be addressed through the DWDM infrastructure, with integrated T-ROADM for flexibility, and metro and long haul 100G transport to meet scale and reach requirements. The infrastructure will deliver fixed, predictable latency without traffic loss, and high reliability. It is also inherently protocol transparent.
Alcatel-Lucent is the leader in optical transport solutions worldwide, and the 1830 PSS — with first to market 100G coherent DWDM — provides the lowest TCO, lowest risk, and
most capable solution available. This is the solution of DWDM and T-ROADM at 100G that service providers need today for DCC.
Responding to increasing security threats and regulation, enterprises face a range of challenges in providing a comprehensive IT security program. Organizations are now shifting to the real-time transfer of data between data centers, and implementing on-the-fly data encryption with key management for security. Physical Layer encryption is the preferred method for securing data across the data center connect (DCC) WAN, deployed across optical fiber and DWDM for converged LAN and SAN traffic. Optical DWDM solutions enable the highest throughput for DCC at the lowest TCO.
The Alcatel-Lucent 1830 Photonic Service Switch (PSS) is a best-of-breed DWDM platform, and the integrated physical layer encryption lowers data center security risks and increases data confidentiality, integrity and availability.
Enterprise Management Associates (EMA) has conducted extensive research investigating the integration and management challenges created by the convergence of on-premise and public Cloud hosted applications. Research conducted in mid-2012 uncovered some compelling statistics about the role of Cloud integration in today's companies:
Nearly 50% of the companies surveyed have already deployed tiered transactions spanning public Cloud and on-premise computing environments (one form of "hybrid Cloud")
Approximately 35% have integrated (or are in the process of integrating) multiple Software as a Service (SaaS) applications.
As one IT professional put it, "Everything is connected to everything." Because of this fact, any discussionof public Cloud as a standalone technology is outmoded. Few modern on-premise applications exist as"silos," and the same is true of Cloud-delivered applications.
In today's business environment, organizations of all sizes are struggling to maintain the advanced IT capabilities they need to be competitive while reining in cost and complexity. Shifting to off-premise hosted models, such as software-as-a-service (SaaS) and business process outsourcing, is a common activity undertaken to manage costs.
One of the main challenges businesses face in adopting cloud and SaaS delivery models is the task of synchronizing data and integrating the multitude of systems already in datacenters with new cloud-based applications, not to mention within the cloud itself. Traditionally, this required organizations to leverage existing tools as well as custom development.
This white paper looks at how two enterprises encountered problems with cloud integration and adopted IBM WebSphere Cast Iron to solve their immediate problems and extend use more broadly across their organizations.
SOA appliances have matured considerably over the last few years. As they have established themselves more firmly in the SOA landscape, vendors have developed a better understanding of requirements, resulting in a level of commonality in some of the key underlying functions such as providing a secure gateway for accessing SOA services.
