Can we create new SharePoint Web Application in SharePoint Online using windows powershell

Question

I want to create a new web application in SharePoint online Office 365, using windows power shell. I had created web application on SharePoint on-premises using windows power shell. I went through some links which I got but they are giving solution on how to create site collection in SharePoint online. We need to implement some CSOM code, and by that we can create site collections, site, list, library in SharePoint online using power shell. Any idea on how to create new SharePoint web-application in SharePoint online using power shell. Following are the links that I have went through,

Any help would be appreciated.

No you can't create a new "web application" in SPO. You can create a new Site collection only. It can be either under /sites or /teams path only.

There is only one "web application" and it is https://tenantname.sharepoint.com. It is also the root site collection.

To create new site collection you can run below powershell:

New-SPOSite -Url https://tenantname.sharepoint.com/sites/mysite -Owner [email protected] -StorageQuota 1000 -Title "My new site collection"

Reference - New-SPOSite

You also need to install the SharePoint online powershell to run this command.

You can also do this via UI.

Go the admin center. You must have global admin or atleast sharepoint admin rights. Click on New > Private site collection. Fill up the details and it will create a new site collection.

Url of admin center:

https://tenantname-admin.sharepoint.com

Using CSOM:

Install SharePoint Server 2013 Client Components SDK

After that you can create site collections via console application after adding the necessary DLLs.

using Microsoft.Online.SharePoint.TenantAdministration;
using Microsoft.SharePoint.Client;
using System;
using System.Security;

namespace CreateSiteCollections
{
    class Program
    {
        static void Main(string[] args)
        {   
            //Open the Tenant Administration Context with the Tenant Admin Url
            using (ClientContext tenantContext = new ClientContext("https://yoursite-admin.sharepoint.com/"))
            {
                //Authenticate with a Tenant Administrator
                SecureString passWord = new SecureString();
                foreach (char c in "password".ToCharArray()) passWord.AppendChar(c);
                tenantContext.Credentials = new SharePointOnlineCredentials("[email protected]", passWord);

                var tenant = new Tenant(tenantContext);

                //Properties of the New SiteCollection
                var siteCreationProperties = new SiteCreationProperties();                
                //New SiteCollection Url
                siteCreationProperties.Url = "https://yoursite.sharepoint.com/sites/codesite";                
                //Title of the Root Site
                siteCreationProperties.Title = "Site Created from Code";     
                //Email of Owner
                siteCreationProperties.Owner = "[email protected]";                
                //Template of the Root Site. Using Team Site for now.
                siteCreationProperties.Template = "STS#0";     
                //Storage Limit in MB
                siteCreationProperties.StorageMaximumLevel = 100; 
                //UserCode Resource Points Allowed
                siteCreationProperties.UserCodeMaximumLevel = 50;

                //Create the SiteCollection
                SpoOperation spo = tenant.CreateSite(siteCreationProperties);

                tenantContext.Load(tenant);

                //We will need the IsComplete property to check if the provisioning of the Site Collection is complete.
                tenantContext.Load(spo, i => i.IsComplete);

                tenantContext.ExecuteQuery();

                //Check if provisioning of the SiteCollection is complete.
                while (!spo.IsComplete)
                {
                    //Wait for 30 seconds and then try again
                    System.Threading.Thread.Sleep(30000);
                    spo.RefreshLoad();
                    tenantContext.ExecuteQuery();
                } 
                Console.WriteLine("SiteCollection Created."); 
            }            
        }
    }
}
