Application Scenarios

Migrating Applications to the Cloud

Challenges

Migrating applications to the cloud involves repetitive work, such as the destruction and rebuild of environments and manually configuring new instances one by one when scaling out applications. Some operations could be time-consuming, such as creating databases or VMs, which usually take minutes to finish. You may have to wait longer when these demanding operations need to be performed one by one. In this case, automating the whole process can improve the migrating efficiency and free you from tedious work.

Solution

AOS enables you to schedule resources, define applications, and deploy services at the same time. With a few clicks, operations such as deployment and destruction can be automatically performed. The only thing you need to do is define your applications and corresponding resources through templates.

Advantages

• Easy to Use

  Design your applications and schedule resources by writing templates. Organize and manage the service easily and efficiently.

• Highly efficient

  Automatically deploy services and destruct environments with a few clicks. Get rid of repetitive work.

• Quick replication of applications

  Applications and resources can be quickly replicated and deployed across different data centers. Templates allow you to quickly create identical applications.

ISV Service Provisioning

Challenges

Independent software vendors (ISVs) deliver software to their customers and have the software deployed in the cloud to provide services. The traditional delivery method is that ISVs provide the software code and platform building guides on their official websites for customers to download. This could be time demanding and costly, because customers have to create resources, configure networks, perform O&M, and manage updates all on themselves. In addition, the traditional method is complex and error-prone, as all the installation is performed manually.

Benefits

AOS templates enable ISVs to deliver software and required resources in a standard manner. By writing templates and deploying application through AOS, software can be easily delivered and efficiently deployed with a few clicks.

Advantages

• Fast delivery

  AOS automatically deploys the software and provisions the resources as specified in the templates you write. The whole process only takes minutes to accomplish.

• Error proofing creation

  All the required resources for the software are defined in the template, which is fixed during delivery and deployment. In this way, mistakes introduced through manual work can be effectively prevented.

• Unified O&M

  AOS enables you to perform software lifecycle operations, including updating and scaling, in a unified and easy manner.

Creating Resources in Batches

Challenges

Assume that you need to create a web application which runs on ten ECSs of different specifications, or you want to create ten databases, you have to create each of them one by one separately, and make sure they can properly work together. The whole process could be complicated and time consuming.

Benefits

With AOS, you can define multiple resources of different services and different specifications in batches in templates, which highly boost the deployment efficiency and brings much more flexibility during configuration.

Advantages

• Quick deployment

  Multiple cloud resources of various types or the same type of resources of different specifications can be created concurrently.

• Flexible configuration

  A wide variety of template syntax allows you to flexibly create and configure resources of various types and specifications.

• Automatic rollback

  When the creation of resources in batches fails, you can choose to perform automatic rollback to save costs.
