Enterprise Software Deployment
The term Enterprise Software Deployment refers to all of the activities that must take place to make a software application available to end users. Enterprise Software Deployment technically begins after a software application has been written, tested, packaged and delivered to an enterprise. Enterprise Software Deployment is a recurring phase of the software development lifecycle, since software is constantly being upgraded, to fix bugs or add new features. This fact makes Enterprise Software Deployment a core element in the administration of IT services within an enterprise.
The traditional method of software deployment places a heavy burden on enterprise IT resources, as they must devote a significant amount of time and attention to the installation and maintenance of all applications that exist within the enterprise computing environment. Conversely, under a SaaS (Software as a Service) model of software delivery, cloud architecture provides a SaaS provider with a mechanism to easily deliver software over the Internet, thereby eliminating the need to deploy software to each application user, as required under the traditional model of software delivery. The SaaS model of software delivery promises enormous savings opportunities for the enterprise, in terms or labor utilization and operational expenses for software deployment and maintenance.
It is important to note the infrequently mentioned missing link in the equation for optimizing Enterprise Software Deployment under the SaaS model of software delivery: SOA (Service Oriented Architecture). SaaS and SOA are the perfect pairing, as SOA-enabled SaaS providers have the capacity to serve thousands of clients from a single instance of an application that is pushed out to an enterprise cloud. This makes the delivery of software a seamless event, due to the additional level of flexibility, scalability and version control that is available when SOA is coupled with SaaS.
SOA (Service Oriented Architecture) provides a framework where software components are delivered as services, which significantly reduces the cost of software deployment and maintenance. SOA facilitates the integration of individual software components into an unlimited number of applications on demand. Each component is maintained by its owner (the web service provider). This provides organizations with the ability to virtually build entire applications without a need to ever worry about software updates or upgrades, as this is handled by the web service providers. Organizations can use the various web services and APIs made available by various web service providers to build a variety of SaaS solutions to be delivered via the enterprise cloud.
