Cloud environments grow organically and often include a dizzying combination of virtual, bare metal and container-based systems. If cloud computing is part of your Linux landscape, you’ll save time and money with a single tool for managing all your Linux resources. SUSE® Manager 4 is a versatile Linux management tool built for the cloud.
What is SUSE® Manager?
SUSE® Manager 4 is a best-in-class open source infrastructure management solution that lowers costs, enhances availability and reduces complexity for lifecycle management of Linux systems in large, complex and dynamic IT landscapes. You can use SUSE® Manager (Figure 1) to configure, deploy and administer thousands of Linux systems running on hypervisors, as containers, on bare metal systems, on IoT devices, and on third-party cloud platforms. SUSE® Manager also allows you to manage virtual machines (VMs).

Keep your Linux systems in sync with a single tool for managing:
• Software updates
• And more
SUSE® Manager 4 extends DevOps ideals to the cloud environment, unlocking a world of rapid deployment and automation.
The Salt automated configuration framework built into SUSE® Manager 4 enables you to create detailed configurations in advance, setting up systems with a few simple mouse clicks. Further integrated software tools help you define channels for pushing updates and new software to the Linux landscape in a way that ensures uniformity and prevents rogue actions by local users and even rogue updates that might either break a service or prevent rollouts. The auditing features included in SUSE® Manager keep watch over your systems, automatically reporting deviations from internal policies or external standards.
The versatile SUSE® Manager 4 tracks, manages and protects your Linux systems no matter where they are. SUSE® Manager can serve a number of roles depending on the needs of your cloud environment. If you prefer to keep management resources on premises, use SUSE® Manager 4 to manage cloud-based Linux server systems from a local data center (Figure 2).

In a completely virtual setting, a cloud-based SUSE® Manager can look after a collection of cloud-based resources (Figure 3). However, if you have all cloud-based resources (such as AWS, Azure, Google, etc.), it makes sense to deploy SUSE® Manager 4 there as well.
Organizations with resources scattered across several offices are still able to manage those servers from within SUSE® Manager 4. Even sending commands to those remotely located servers (if they are hosted in on-premises data centers of cloud-hosted servers) is made quite easy (Figure 4).

The scenarios depicted in Figures 2-4 suggest an endless variety of options, with SUSE® Manager 4 managing Linux systems in any combination of bare-metal, container and virtual environments. In all these scenarios, the IT staff just has to learn one tool and one set of procedures.
Built for the Cloud
SUSE® Manager 4 offers effective lifecycle management services for Linux systems in both public and private clouds. Pre-built system images for SUSE® Manager 4 are currently available in Amazon EC2, Google Compute Engine, Microsoft Azure and other leading cloud environments. You can rest assured that SUSE’s extensive network of cloud partners enables you to deploy SUSE® Manager 4 in the cloud environment you’re using now.
If you manage your cloud infrastructure through the OpenStack orchestration framework, SUSE® Manager 4 will fit in seamlessly with your existing operations, providing lifecycle services such as configuration, auditing and software updates for systems deployed through OpenStack.
SUSE® Manager 4 includes a number of built-in features for easy administration within cloud environments. For instance, when you “clone” a new image from a running system, SUSE® Manager offers a graceful way to register the clone and bring it under central management with minimal configuration.
SUSE also provides the SUSE® Manager 4 Proxy tool, which is designed to help move content closer to groups of clients and is a part of SUSE® Manager 4’s scalability.
Operation of the proxy is completely transparent. The SUSE® Manager 4 Proxy (Figure 5) looks like a managed client to SUSE® Manager 4 Server and like a server to the managed clients. Managed clients talk to the Proxy only, and the Proxy in turn communicates to the SUSE® Manager 4 Server.
All software packages that pass the Proxy are cached, and subsequent client requests for these packages are resolved from the cache.
Do note that SUSE® Manager 4 Proxy is a separate license from SUSE® Manager 4. .
SUSE’s Bring Your Own Subscription (BYOS) model adds flexibility to cloud configurations. BYOS allows you to transfer an existing SUSE® Manager 4 subscription to a cloud-based subscription administered through a certified SUSE® Cloud Service Provider, such as Amazon AWS, Google Compute Engine or Microsoft Azure. The BYOS model makes it easy to migrate to the cloud now or at a later date while maintaining continuity in subscriptions and support.
Today’s enterprise moves too fast for yesterday’s tools. SUSE® Manager 4 is a powerful solution for managing your Linux resources from a single interface.
