Deploying Applications Using DevOps

Traditional ways of development and operations is slowing down innovation

Development Operations

We need to push new features and

functionality ASAP.

We need to keep it stable, Follow the

process and deployment schedule to ensure

predictability

Speed to market

Cost Quality


DevOps is a new approach to software delivery that aims at breaking the silos between development and operations.

Development Operations

Communication+

Integration

Speed to market

Cost Quality

In an study conducted by Vanson Bourne for CA, they found that DevOps is delivering 20% improvement in time to market, 22% increase and quality and 18% reduction is costs.

Wikipedia defines DevOps as “DevOps (a portmanteau of development and operations) is a software development method that stresses communication, collaboration and integration between software developers and information technology (IT) professionals. DevOps is a response to the interdependence of software development and IT operations. It aims to help an organization rapidly produce software products and services.”


While the significant aspects of transformation is cultural change, automation is critical for DevOps success

Unisys recommends utilizing a pre-defined set of best practice processes and roles for its clients, as well as an integrated set of tools required to enable these processes and provide significant automation to the configuration management, promotion and build processes of applications and infrastructure.

Role Responsibilities Incident Management group Detect and report defects that cause system outages. App Support Developers Diagnose source of defect.

Code and unit test solution. Check solution into appropriate code branch from main code line. Determine any special issues related to installing the solution into

production and communicate them to the Build Team. Merge the change into other App Support code branches. Alert projects to any changes in the production code line so that

App Projects can merge them into App Projects releases. SCM Manager (App Support) Create a code branch from the current production baseline for use

by the App Support developers for approved request. Assist in merging the changed code back into the main code line. Create a new code baseline on the main code line.

Build Manager (App Support) Builds the software for deployment into a test environment Builds the software for deployment into the production environment

Testers Test the change against the established test suites and report findings.

Build Team Install software in the test environment. Install software in the production environment.

App Projects Developers Merge the change into in-progress App Projects code branches as needed.

Step Action Role 1 Approved work is identified, either as a production defect or approved Change

Request. There are two pathways that work can be identified:

Production defect reported by the Incident Management group Approved Change Request targeted for a upcoming release

Either case indicates work that the App Support development team needs to perform and is an entry point into this procedure.

Requestor

2 If production defect, developers confirm need for a code change. Some production defects can be resolved via a workaround or data changes with no CI changes required. If this is the case, there are no branch and merge repercussions and the rest of this procedure is not executed.

App Support Developers

3 SCM Mgr creates code branch (if it doesn’t already exist) from production baseline. At the request of the L3 Lead, the SCM Manager creates a branch of the production baseline if it does not already exist (depending on the version control tool used by the application). This gives the App Support Developers a copy of the current production software in a work area so that they can begin the work to code the solution. For bugfixes, it is considered to be good practice to create a Bug/ Fix branch for a production release immediately after a new production release is merged into the product’s main code line and is baselined. But if this has not happened, the bugfix code branch should be created here. For non-defect Change Requests, a code branch may already exist for the current release; if not, the code branch should be created here.

Automated ScalingSecurity

•Stable transaction-oriented systems on the back end •Fast-changing customer-facing applications in the front-end

•Launch several software changes a day/week•Hosted in the cloud and loosely integrated

•Upgrades are seamless to end-user• Issues in one service do not harm overall operations

•Analyze data in real-time with every touch within the app•Change application based on user behavior

•Business users change processes – flexible workflows•Eliminate unnecessary processes without needing a developer

•Elasticity provided by cloud infrastructure •Cybersecurity should be part of overall application
