2. Load Balancing and Concurrency
As businesses grow, leading to increased traffic on their applications, load balancing and concurrency are two crucial considerations faced by an enterprise which must be dealt with and closely observed. With increase in traffic enterprises feel the need of extensive scalability on the application side so that the load is distributed across the servers to achieve optimal performance.

This is where load balancing comes into play and most enterprises today in a transition phase of extensibility face this as a major problem. Similarly, enterprises also begin to need concurrent infrastructure to run applications so that the architecture and hardware does not reach saturation.

From a cloud computing perspective, companies like Amazon, Google, and Microsoft are putting together enormous numbers of infrastructures that deliver a high scale and overwhelming load. Here is where the infrastructure is a boon for enterprises that can host applications (off premise): they can be at peace instead of thinking about the capital expenditure necessary to put together a hardware infrastructure to support it across the board.

What the infrastructure promises is an on-demand ‘Scale Out’ to meet the demands of tomorrow.

3. Security
Security is the first and foremost concern when it comes to integration in a distributed environment. Compliance with regulatory policies is an important factor that drives the creation of a robust security infrastructure for message exchange. In addition it also becomes important to control the access of service operation in a cloud computing environment.

4. Governance
Service governance, or service management, is the commonly used term in the field of messaging infrastructure governance. Having positioned a SOA/ESB infrastructure, it is important to check and maintain the health of the services being deployed. In addition, in a distributed-computing environment in which messages converge or are disbursed, based on the needs of the end user and application, it is critical to keep an eye on governance.

Thus, enabling all the governance consideration becomes crucial for an enterprise to position its messaging infrastructure.
