Nutanix Calm™应用程序编排器是企业中企业用户提供自助服务的门户。他们的旅程始于通过冷静，启动应用程序管理项目和用户的旅程，并在第二天管理常规操作任务。

作为日常工作的一部分，用户依靠应用程序中的“缩放” VM来支持VMS中运行的工作负载的不同需求。在平静下，蓝图内置的“刻度”轮廓动作用于通过部署VM的其他实例来实现水平缩放。但是，直到平静3.2.0之前，如果用户想垂直缩放VM，例如添加更多内存，或更改运行应用程序上的任何VM属性，则不可能直接，他们必须通过管理员。

例如，通过平静支持企业中的零售交易管理的多层应用程序的数据库管理员（DBA）希望以更高的配置升级主数据库，以支持每秒更多的交易。在这种情况下，一个典型的过程是：

DBA与可以访问云提供商的IT管理员联系。

然后，DBA提供了VM的详细信息和所需的配置。

然后，它进行了必要的更改。

然后，DBA等待变化以镇定反射。

作为手动过程，这里涉及的复杂性和交接是一个开销。自动化是降低这种操作复杂性的关键。以前，该问题已解决了Call IaaAS应用程序（单个VM蓝图）。自助服务用户可以导航到运行应用程序，并将VM规格更改为所需值。但是，没有防护轨来防止用户垂直将VM缩放到一定程度上，从而导致集群用尽资源。您当然可以设置配额，但是仍然会导致该VM消耗项目配额下可用的所有资源。

平静3.3.0引入了一项新功能，以克服上述问题。添加了一个称为“ Update Config”的新概念。蓝图内的蓝图开发人员定义了“更新配置”，它包含应用程序内服务VM的所需配置状态。

让我们进一步了解有关这些“更新配置”如何与CALL托管的三层应用程序一起使用的“更新配置”，该应用程序由MySQL®数据库，Apache®应用程序服务器和负载平衡器组成。

蓝图开发人员希望为MySQL服务提供T恤尺寸配置。

蓝图开发人员使用“更新配置”选项添加上述配置。

“更新配置”由配置组成，用于修改VCPU，每个VCPU和内存（GIB）。这些参数上允许的操作相等，增加或减少。当启用了可编辑选项时，蓝图开发人员还可以使用Min和Max选项为每个属性添加边界限制。此外，“更新配置”还包括添加/修改/删除磁盘，磁盘空间，类别和网络的选项。

针对小型，中和大型MySQL数据库的“更新配置”的最终蓝图看起来如下图：

包括用于垂直缩放的运行手册的更新操作也可以通过在缩放操作之前和/或之后必须执行的任务和动作来构成。在此示例中，在垂直缩放MySQL数据库之后，蓝图开发人员选择重新启动依赖服务。

成功启动应用程序后，DBA将导航到应用程序内的管理选项卡。配置为切换数据库VM配置的三个操作可以从那里执行。在执行过程中，DBA可以将当前配置与成功执行“更新操作”后将更新的配置进行比较。

有了这些新功能在Calm 3.3.0中，蓝图开发人员将能够

为VM提供垂直缩放功能

控制消费者/操作员可以更改哪些VM属性以及在多大程度上

蓝图中“应用程序编辑”配置的功能将使自助服务用户仅单击一次单击即可垂直扩展到其所需配置。

此功能目前可用于Nutanix®云平台。有关更多信息和详细的用户指南，请参阅Nutanix平静文档。

The Nutanix Calm\u2122 application orchestrator is the gateway to self-service for business users in the enterprise. Their journey starts with managing projects and users via Calm, launching applications, and managing routine operational tasks on day two.<\/p>
As a part of their daily routine, users rely on \"Scaling\" VMs in the application to support the varying demands of workloads running in the VMs. In Calm, the \"Scale\" profile action built into the blueprint is used to achieve horizontal scaling by deploying additional instances of a VM. However, until Calm 3.2.0, if the users wanted to vertically scale a VM, for example add more memory, or change any of the VM attributes on a running application, it was not directly possible and they had to go through an admin.<\/p>
As an example, the database admin (DBA) of a multi-tier application managed by Calm supporting retail transactions in an enterprise wants to upgrade the primary database with a higher configuration to support more transactions per second. A typical process in this scenario would be:<\/p>
The DBA contacts the IT admin who has access to the cloud provider.<\/li>\t
DBA then provides the details of the VM and the required configuration.<\/li>\t
IT admin then makes the necessary changes.<\/li>\t
The DBA then waits for the changes to be reflected in Calm.<\/li><\/ol>
As a manual process, the complexity and hand-offs involved here are an overhead. Automation is the key to reduce such operational complexity. Previously, this problem was solved for Calm IaaS Apps (Single VM blueprints). A self-service user could navigate to the running application and change the VM specifications to the desired values. However, there were no guard rails to prevent a user from vertically scaling the VMs to an extent that it would result in the cluster running out of resources. You could set a quota of course, but it would still result in this one VM consuming all resources available under the project quota.<\/p>
Calm 3.3.0 introduces a new feature to overcome the problems described above. A new concept called \"Update Config\" has been added. An \"Update config\" is defined by the blueprint developer inside the blueprint, and it contains the desired configuration state for the service VMs inside the application.<\/p>
$\"//www.jhbzcj.com/next/community-blog-154/\"$ <\/figure>
Let us learn more about how these \u201cUpdate Configs\u201d that can be used with an example of a Calm managed three-tier application consisting of a MySQL\u00ae database, Apache\u00ae application server, and a Load Balancer.<\/p>
$\"//www.jhbzcj.com/next/community-blog-154/\"$ <\/figure>
The blueprint developer wants to provide the DBA with T-shirt size configurations for MySQL service.<\/p>
$\"//www.jhbzcj.com/next/community-blog-154/\"$ <\/figure>
The blueprint developer uses the \"Update Config\"option to add the above configurations.<\/p>
$\"//www.jhbzcj.com/next/community-blog-154/\"$ <\/figure>
An \"Update Config\" consists of configuration to modify vCPUs, Cores per vCPU, and the Memory (GiB). The operations allowed on each of these parameters are Equal, Increase, or Decrease. When the Editable option is enabled, blueprint developers can also add boundary limits for each of the attributes using the Min and Max options.\u00a0 In addition, the \u201cUpdate Config\u201d also includes options to add\/modify\/remove Disks, Disk space, Categories, and Networks.<\/p>
The final blueprint with \"Update Configs\" for Small, Medium, and Large MySQL database looks like the below image:<\/p>
$\"//www.jhbzcj.com/next/community-blog-154/\"$ <\/figure>
The Update action which includes the runbooks for vertical scaling can also be clubbed with tasks and actions that have to be executed before and\/or after the scaling action. In this example, after vertically scaling the MySQL database the blueprint developers choose to restart dependent services.<\/p>
$\"//www.jhbzcj.com/next/community-blog-154/\"$ <\/figure>
After the application is successfully launched, the DBA navigates to the Manage tab within the application. The three actions configured to switch the database VM configurations can be executed from there. During execution, the DBA can compare the current configuration with the configuration that will be updated after successful execution of the \u201cUpdate Action\u201d.<\/p>
$\"//www.jhbzcj.com/next/community-blog-154/\"$ <\/figure>
With these new capabilities in Calm 3.3.0, the blueprint developer will be able to<\/p>
Provide vertical scaling capabilities for the VMs<\/li>\t
Have control on what VM attributes can be changed by the consumers\/operators and to what extent<\/li><\/ul>
The power of \u201cApp Edit\u201d configurations in the blueprint will let the self-service users scale the VMs vertically to their desired configurations with just a single click.<\/p>
This feature is currently available for the Nutanix\u00ae Cloud Platform. For more information and detailed user guide, please refer to the Nutanix Calm documentation.<\/p>
