Businesses are quickly implementing virtual private networks in attempts to connect far-flung network users. Despite their popularity, however, two key issues remain: data security and reliable, consistent application delivery. This article explains these key VPN issues, and shows how to implement both security and reliability on your VPN with the implementation of next-generation Quality of Service (QoS), also known as Application Service Quality (ASQ).
Message queuing enables applications on geographically separated systems to interact effectively, without synchronizing activities on communication ends. This makes message queuing a preferred technology for many large-scale e-commerce applications. MQSeries, IBM's message queuing product, can be used for exchanging messages between applications running on the same system, as well as on different systems.
