Automate application release and ramp up release velocity

DevOps is all about increasing application release velocity and generating fewer defects and production outages. In today’s superheated business environment, achieving these goals can give a company the edge to outdistance competitors. But no matter how closely you align Dev, QA, and Ops, the process can derail when changes to requirements slip through unnoticed. And that can cause outages, potentially jeopardizing crucial updates to mission-critical applications and hurting your bottom line.

 

Typically when developers find a bug and decide to change the environment by, say, adjusting CPU or RAM requirements, they need to go through a series of manual steps. They then need to send emails documenting the changes to QA, the staging team, and the production team. This leaves a lot of room for error. In my work in HP Software Professional Services, I’ve seen many instances in big companies where communication breaks down, a change gets past, and when an application is in production, there’s an outage.

 

Infrastructure as code                                                                                                                                    

So how do you prevent such slips? By creating a topology-based model using HP CODAR, you can document your infrastructure and save it as code. Rather than writing scripts to define your infrastructure, you can simply drag-and-drop elements, such as a database, a middleware, and a user interface, into a topology model. You can then export that model via an XML or JSON file, and store the file in the same repository with the application code.

 

When developers make changes to that infrastructure, they register those changes in the XML or JSON file. The infrastructure code then gets built automatically. When you run CODAR on top of HP Cloud Service Automation, the XML file will automatically accompany the application code when it goes to the cloud service automation tool. The end result? Application release automation, with faster delivery and less risk of outages.

                                                                                                                         

Making the job easier for Apps and Ops

A topology-based infrastructure model benefits Apps and Ops in a number of ways:

 

  • Faster, more reliable communication between Apps, QA, and Ops. Developers no longer need to send emails when they make changes to the infrastructure. Automatic triggers go out to the infrastructure teams in QA, staging, and production, letting them know that the infrastructure has been updated and asking them to review their deployment strategies. No more back-and-forth communication.
  • Minimize inconsistent deployments and make disaster recovery easier. By linking application code to infrastructure design, when something breaks, the Ops team can easily revert to the previous code iteration. Without a topology model, going back to the previous infrastructure would be a much more labor-intensive task.
  • Better pipeline management. A topology-based model lets you see when applications are scheduled to deploy. If you can anticipate what is coming, you can better manage your resources. For example, if you know when QA will be done, you can make infrastructure available for the next application. You get complete visibility into the application pipeline, and you can automate application deployment.

 

HP CODAR is part of the HP DevOps architecture, which aligns with industry best practices. Pre-packaged solutions incorporate HP and third-party tools such as Jenkins, Chef and Eclipse, enabling you to quickly build a DevOps platform. At HP, we provide services ranging from workshops to implementation to managed services.
