Deployment

Deployment is the final and the last stage of the software development process in which the application or the system developed is deployed for use or made available to the consumers. This phase includes several activities that are carried out before the actual deployment of the application whereby the live environment is configured and other components put in place. Development and testing are done and deployment is a process that puts the software into use for the intended consumers.

Furthermore, deployment also entails ongoing processes for example, monitoring the performance of the system, problem solving in case of any occurrence of a problem and evaluating for support and maintenance. This continuous check enables one to appreciate the efficiency of the software and I case of need for modification, this can be done easily.

At the current level of development of new technologies it is crucial for organizations to provide proper implementation of their software solutions so as to meet the current market needs and develop quality software solutions.

Deployment Strategies

As for the deployment strategy, different projects imply different strategies, and choosing the right one will allow delivering new software to customers without much trouble. Some common deployment strategies include:Below are some of the deployment strategies which are most often applied:

Blue-Green Deployment: This approach entails having two similar production systems, one termed ‘blue’ and the other ‘green’, both of which are mirror images of each other; one is active at any one time. This reduces the time of repair and makes it possible to easily revert the changes in case of problems.

Rolling Deployment: In this method, updates are done cumulatively on the different servers. New versions are released to a number of servers while the others remain with the previous version to avoid disruption.

Canary Deployment: This is a process whereby the new software version is released to the public but only to a certain number of users and the developers are able to monitor the performance of the software as used in the real world without interfering with the other users.

Feature Flags: This technique allows for getting new features into production but the features are not on by default. The users or groups can choose to activate the features selectively, hence avoiding massive exposure while the features are being tested.

Signs of Successful Deployment

A successful deployment is that which is done without disturbing the users and with ease from the development to the production environment. It is hence recommended that the application should be run in a controlled test environment before running it in the live system so as to avoid developing problems that may come up in future.

Maintenance is also crucial in the postdeployment stage, since it is possible to detect and eliminate the common problems, or, for example, performance issues. Another technique that can be used is the phased rollouts where the updates are first released to a subset of the users and then the feedback can be collected before a general rollout.

Thus, the effective strategies for deployment guarantee the operational efficiency, improve the satisfaction of customers and facilitate the delivery of new features and updates.
