AWS offers serverless storage through the Amazon Elastic File System (EFS), allowing you to build and configure your shared file systems quickly and easily. Amazon EFS is optimized to handle the majority of applications and features high availability and extreme durability for your data. With scalable, agile storage that grows and shrinks with your needs, Amazon EFS reduces costs by ensuring that you only pay for what you use. In addition, Amazon EFS will automatically move your rarely-accessed files to lower cost storage. Amazon EFS is your solution if you need to quickly and easily share data with no management required.
Amazon FSx is a fully Windows-compatible storage system with high availability, default backups for all files, and automatically updated hardware patches and provisioning. If you rely on a Windows-based file server that is reaching capacity or is nearing end-of-life, Amazon FSx may be the solution for you. Amazon FSx offers low latency, guaranteed performance, and industry-leading security for your business files.
In addition to working seamlessly with Windows File Server, Amazon FSx offers storage for NetApp ONTAP, Open ZFS, and Lustre. Simply choose the system you already use and your data can be transferred seamlessly to your new cloud-based file system. With Amazon FSx, you only pay for what you use, eliminating the need to invest thousands in on-site storage in favor of pay-per-use storage with Amazon FSx.
Amazon Elastic Block Store (EBS) low latency, high performance block storage for use with Amazon Elastic Compute Cloud (EC2) instances. Amazon EBS supports SSD-based or HDD-based volume types and includes encryption for your data, both in-flight and at rest. As always, Amazon EBS is a cost-effective, scalable, and easy to use. Amazon EBS supports service levels that specialize in everything from highly available, low latency block storage to very low cost, durable storage for archived data blocks.
Amazon File Cache offers a unified view of your files, regardless of storage location. You can link physical servers, Amazon FSx, Amazon S3, or other cloud datasets within the Amazon File Cache. This low-latency cache makes it easier to process your file data by presenting a cohesive look at everything you have linked to the Amazon File Cache.
Azure AD DS offers a streamlined deployment process, providing organizations with the opportunity to set up and configure their managed domain services in the Azure environment quickly. It also seamlessly integrates with existing on-premises infrastructure, extending your organization’s Active Directory environment to the cloud.
With this cloud-based service, organizations can explore a consistent management experience by supporting similar management tools and techniques used within on-premises Active Directory. This familiarity process simplifies adoption and enables centralized management of user identities, groups, and resource access.
A significant selling point of the Azure AD DS is its ability to join Azure VMs to the managed domain, providing seamless integration between an organization’s cloud-based resources and its domain services. By emulating a traditional domain join, Azure AD DS ensures compatibility with existing workflows and applications that rely on Active Directory.
Azure AD DS allows organizations to manage Azure VMs and other resources through a centralized management interface. This provides a consistent experience for administration and configuration tasks. Furthermore, this level of centralization simplifies management, reduces administrative overhead, and enhances overall efficiency.
Azure AD DS leverages identities stored in the Azure Active Directory to provide several domain services in the Azure environment. Firstly, the services use Azure AD identities to authenticate users who are accessing domain-joined resources, such as Azure VMs. Azure AD DS also relies on its Active Directory identification for user and group management by creating and managing user accounts and security groups in Azure AD.
Microsoft also provides a tool, Azure AD Connect, which enables the synchronization of on-person Active Directory identities with Azure AD. This synchronization process ensures that user accounts and security groups from the on-premises infrastructure are replicated to the Azure AD, making them available by the Azure AD DS.
Azure AD DS supports the deployment of legacy applications by providing a managed domain that can be used to join Azure VMs. With this, organizations can run legacy applications that require Active Directory in the cloud without deploying and managing a domain controller.
By deploying legacy applications in the cloud, organizations can reduce costs associated with developing and maintaining infrastructure, increase agility by creating and managing domains in minutes, and enhance their security backed by Microsoft’s world-class security infrastructure.
With Azure AD DS, organizations can create and configure GPOs using familiar Group Policy management tools and techniques used in a traditional domain, such as the GP Management Console and the GP Object Editor. With these tools, you can define various policies, settings, and preferences within GPOs, all of which are tailored to your specific server management requirements.
Following the creation and configuration of GPOs, Azure AD DS ensures their proper application to domain-joined servers. This cloud-based service functions as the domain controller, allowing it to deliver and enforce GPO settings to the managed servers. Other GPO functions include linking and inheritance, security filtering, and GPO enforcement and reporting.
By utilizing Azure Active Directory Domain Services, organizations have the opportunity to harness the extensive range of robust features offered by the Active Directory, encompassing the utilization of advanced authentication protocols, such as Kerberos and NTLM.
This strategic implementation guarantees highly secure authentication processes and robust access control mechanisms for Azure virtual machines, thereby significantly fortifying the overall security posture of your organization’s cloud infrastructure.
Azure AD DS ensures high availability within a specific Azure region by employing redundant domain controllers. It deploys domain controllers across fault domains and availability sets, minimizing the risk of a single point of failure. It automatically switches to a healthy domain controller during failures or maintenance events, ensuring uninterrupted domain service availability.
As such, organizations can benefit from Azure AD DS automatic failover mechanisms to swiftly transition to a healthy domain controller in case of an outage or failure. The system also extends its high availability capabilities beyond a single region by supporting multi-region failover. The failover process is handled seamlessly behind the scenes without the user or administrator requiring any manual intervention.
With Azure AD DS, enterprises of all scales are exposed to a comprehensive cloud-based offering that provides compatibility with on-premises Active Directory, enabling organizations to utilize domain services without the need to deploy and maintain their domain controllers. This process introduces a world where domain services adapt to the cloud effortlessly, empowering organizations to thrive in the digital era.
