The cloud resources (like servers and storage) are owned and operated by a third-party cloud service provider and delivered over the internet. With a public cloud, all hardware, software, and other supporting infrastructure are owned and managed by the cloud provider. Microsoft Azure is an example of a public cloud.
Today, there are three main public cloud providers: AWS, Microsoft and Google. These providers deliver their services over the internet or through dedicated connections, and they use a fundamental pay-per-use approach. Each provider offers a range of products oriented toward different workloads and enterprise needs.
Public clouds are the most common type of cloud computing deployment. Microsoft Azure is an example of a public cloud. In a public cloud, you share the same hardware, storage and network devices with other organisations or cloud “tenants,” and you access services and manage your account using a web browser.
The main differentiator between public and private clouds is that you aren't responsible for any of the management of a public cloud hosting solution. A large company may choose a private cloud, while a smaller business might choose a public cloud.
Private cloud is a type of cloud environment where the cloud software is managed by internal IT. For example, in private IaaS, internal operations installs and manages the cloud management platform (CMP) for its infrastructure.
The public cloud is defined as computing services offered by third-party providers over the public Internet, making them available to anyone who wants to use or purchase them. They may be free or sold on-demand, allowing customers to pay only per usage for the CPU cycles, storage, or bandwidth they consume.
A hybrid cloud is a computing environment which combines a public cloud and a private cloud by allowing data and applications to be shared between them. Read more about hybrid cloud capabilities and getting started with Azure.
The private cloud is server based. Public cloud services like AWS are an on-demand marketplace, where developers can spin up hundreds of instances on the fly. Applications can auto-scale capacity up (or down) based on demand, achieving instant global scale.
Both Azure and AWS are similar in offering PaaS capabilities for virtual networking, storage, and machines. However, Azure gives stronger and faster PaaS capabilities which nowadays is more important part of Cloud infrastructure. Thus, you have 100% focus on innovation if you develop Azure PasS solutions.
Whereas AWS has grown into the largest cloud services provider by being first to market and by being the more developer-friendly of the two platforms, Azure caters better for larger organizations already committed to Microsoft products moving an existing infrastructure to the cloud.
Microsoft Azure is somewhat easy but complicated to configure. Azure far more better in new portal, and offers vast services, not to learn in a day. But easy to move around.
Azure as a platform can be learned without knowing any programming at all. Although if you wish to deploy an application to Azure then you may need to write some configuration code or a deployment script. But for normal infrastructure management and other tasks you can use Azure.

Enable the Windows boot menu in the serial console
- Connect to your Windows VM or virtual machine scale set instance by using Remote Desktop.
- From an administrative command prompt, run the following commands: bcdedit /set {bootmgr} displaybootmenu yes.
- Reboot the system for the boot menu to be enabled.
To do that,
- Log in to Azure portal (azure.com) as Global Administrator.
- Go to Virtual Machines.
- From the VM list, click on the Windows server 2019 VM we created in the earlier step.
- In VM properties page, verify it doesn't have public IP assigned.
- To test the bastion service, click on Connect.
Go to "Reset Password" on the left pane of your Azure portal window for your VM. Now add username and password and update. With this new username and password, you can login to VM machine and find your old/original username.
If you already have a VM that you want to domain-join, skip to the section to join the VM to the managed domain.
- From the Azure portal menu or from the Home page, select Create a resource.
- From Get started, choose Windows Server 2016 Datacenter.
- In the Basics window, configure the core settings for the virtual machine.
Add Static Public IP to an existing Azure VM
- Login to MS Azure portal.
- Click “Virtual Machines” from the left menu.
- Select an existing virtual machine from the list.
- Under Settings, click "Networking".
- Click "Network Interface".
- Under Settings, click "IP Configurations".
- Click IP configuration (e.g. ipconfig1).
Configuring a VM for direct RDP access
- Run an RDP server or use built-in options to enable Remote Desktop for all users on the system. Example: Enabling remote connections in Windows 7 and Windows 2008 R2. Click Start, and then right-click Computer.
- Verify that port 3389 is open on the VM operating system firewall.
SSH into the VM using PuTTY
- For Connection type, make sure the SSH radio button is selected.
- In the Host Name field, enter azureuser@<public ip> (your admin username and IP will vary)
- On the left, expand the SSH section, and click on Auth.
- Click on Browse to look for your private key (. PPK), and click Open.
- To launch the SSH session, click Open.
Configure Remote Desktop from the Azure portal
- Click Cloud Services, select the name of the cloud service, and then select Remote Desktop.
- Choose whether you want to enable Remote Desktop for an individual role or for all roles, then change the value of the switcher to Enabled.
Access remote resources feedIn a browser, navigate to the Azure Resource Manager-integrated version of the Windows Virtual Desktop web client at microsoft.com/arm/webclient and sign in with your user account.

docx - Which secure VPN technology is used for hybrid cloud connectivity over the public Internet Selected Answer L3VPN Correct IPsec VPN | Course Hero.
Cloud networking, or cloud-based networking, gives users access to networking resources through a centralized third-party provider operating inter-connected servers. This involves connecting to a Wide Area Network (WAN) or other internet-based technology, and helps to distribute content quickly and securely.
AWS Direct Connect is a cloud service solution that makes it easy to establish a dedicated network connection from your premises to AWS. AWS Direct Connect lets you establish a dedicated network connection between your network and one of the AWS Direct Connect locations.
Which AWS service allows companies to connect an Amazon VPC to an on-premises data center? (VLAN). You can take advantage of these logical connections to improve security, differentiate traffic, and achieve compliance requirements.
Follow these steps to set up the JDBC connection.
- Step 1: Create a security group for AWS Glue ENIs in your VPC.
- Step 2: Create an IAM role for AWS Glue.
- Step 3: Add a JDBC connection.
- Step 4: Open appropriate firewall ports in the on-premises data center.
- Step 5: Test the JDBC connection.
To implement this configuration
- Enable communication between the VPC and your own on-premises network over an AWS Site-to-Site VPN connection.
- Test the AWS Site-to-Site VPN connection you created in the previous step.
- Create a Client VPN endpoint in the same Region as the VPC.
