Deployment is the ultimate crucial step for all software application development; like actors, stagehands, and producers in a theatrical production, none of that hard work matters until the lights go down and the curtains go up. Did someone forget a line?
Software deployment occurs not only when software goes to final production and is available to users, but also at each of the key stages in the lifecycle of the application, including the point at which software is instantiated for development, test, and staging environments as well. In every case, a complex technological handoff must occur, involving configuration, validation, and many other critical tasks. When that handoff doesn’t go smoothly in pre-production, delays, bottlenecks, and security lapses may occur; when deployment goes wrong at production, users may experience poor service, application downtime, or worst of all, a security breach.
The philosophies and tools employed for smooth application deployment depend on the platform architecture you choose for your software. Do you wish to run in a private, public, or hybrid cloud environment? Or perhaps another multi-cloud variation? Is your codebase private legacy, open source, or a mix? The answers to these questions will largely dictate what deployment strategy is best for you.
First, since today the digital world is by far web-based, software enterprises predominantly employ some form of cloud computing to deliver their products and services. Cloud computing comprises everything from servers and databases, to tools, applications, software and networking components necessary to ship products to the consumer. The cloud computing architectures prevalent today fall into several major categories: private, public, and hybrid- or multi-cloud.
Private clouds connect to the internet via a private network for a single customer. Private clouds may be built internally by the company itself, or built specifically for the customer by a private third party. Public clouds, on the other hand, are built by third parties who have a vast array of clients, and the architecture is not available to the businesses purchasing those services. Hybrid clouds any two or more discrete cloud computing centers, such as private-private, private-public, or public-public. A combination of multiple public clouds is also referred to as multi-cloud.
