# Server Deployments
The **Autosky deployment** feature allows new system versions to be made available to instances in a controlled and traceable way.
Deployments are performed from the **preparation server**, which serves as the base to generate the new version that will be applied to the environment. For this reason, this feature is only available for **Scaling** environments.
In **Servers**, the **Deployments** page centralizes:
* Creation of new server versions
* Configuration of deployment methods
* Full tracking of executed deployments
* Detailed visualization of each process step
* Deployment scheduling
***
#### Deploy new version
This is the main area to start a new deployment, allowing immediate or scheduled deployments of a new system version. The section includes the title **“Deploy new version”**, a description explaining execution options, and an informational notice stating that deployment models have been unified under the **Optimized** option.
***
#### Deployment mode
Users can select:
* **Optimized (default)**
* **Schedule**
***
### Optimized
The **optimized deployment** is the standard and unified model in **Autosky**.
It centralizes the entire deployment process into a single automated flow, ensuring simplicity, control, and traceability.
**What is performed automatically**
During deployment, the system performs the following steps:
1. Initial validation
2. Stop preparation server (when configured)
3. Image creation
4. Model creation
5. Instance replacement (when applicable)
6. Finalization
**Screen elements**
* **Notification fields**
* **Additional options**
* **Deployment history**
***
**How to deploy a new version**
1. **Select the Optimized mode**
2. **Configure the desired options**
* **Lock instances**\
Prevents changes during the deployment process
* **Stop preparation server when creating image**\
Ensures greater consistency when generating the new version
3. **Enter notification emails (optional)**
Allows you to specify email addresses that will receive deployment notifications.
4. **Click publish**
5. **Track progress through the page history**
***
#### Deployment history
This section displays all completed deployments.
**History table**
Each record shows:
* **Execution date and time**
* **Process steps**
* **Time per step**
* **Deployment status**
* **Generated version**
Status is displayed visually, making it easier to identify successful executions.
**Deployment details**
Clicking a deployment in the history opens a modal with full execution details.
**General summary**
* Deployment status
* Execution owner
* Model version
* Start and end date/time
* Total duration
***
**Detailed steps**
Each step of the process can be expanded to view more information.
**Initial validation**
* Preliminary process checks
* May include actions such as retrieving server information
***
**Stop preparation server**
* Indicates whether the server was stopped
* May appear as not applicable
***
**Create image**
* Process of generating the new image
* Includes request and tracking of the creation
***
**Create models**
Displays actions such as:
* Identifying compatible resources
* Creating the main model
* Creating a backup model
* Removing old models
***
**Replace instances**
* Shows whether instances were updated to the new version
* May not occur depending on the scenario
***
**Finalization**
* Shows how the deployment process was completed
***
### Deployment scheduling
It is also possible to schedule a deployment for a specific time.
**How to schedule**
1. Select the Schedule option
2. Set the desired date and time
3. Click Schedule
4. Confirm the action
After scheduling, execution will occur automatically at the defined time.
**Scheduled list**
After scheduling, it will appear in the history along with all other deployments.
