Easily manage backups for all devices from a single console, ensuring seamless protection for VMware and Hyper-V virtual machines. With just one click, you can back up Microsoft SQL Server databases, and the solution supports all major virtual machine types, including VMware, vSphere, Microsoft Azure, and Amazon Web Services (AWS). Proven through thousands of tests in various environments, the backup success rate reaches up to 99%. It offers flexible cloud-free space allocation for backups, allowing you to allocate just the right amount of storage. The system can automatically back up your system, disks, and other data on a schedule, with quick and easy restoration of entire VMs, files, and objects. This data protection solution is ideal for environments running Hyper-V 2012 R2, 2016, and 2019, offering automatic, regular backups for Hyper-V virtual machines on a daily, weekly, or monthly basis, or triggered by specific events, including USB plug-ins. Hot backup ensures that Hyper-V VMs are protected in real-time, guaranteeing a 100% backup and restore with zero downtime. Incremental and differential backup options help save storage by only backing up modified files or folders on Hyper-V environments.

Atlassian Data Center serves as a self-managed enterprise solution that is crafted to deliver high availability, robust performance at scale, and versatile infrastructure options for essential Atlassian applications. It accommodates various products including Jira Software, Confluence, Bitbucket, Jira Service Management, Crowd, and Bamboo, empowering organizations to tackle intricate demands with its comprehensive enterprise-grade features. The Data Center offers the flexibility to deploy applications on proprietary hardware, within virtualized settings, or via cloud service platforms such as AWS and Azure. This adaptability enables businesses to advance their IT infrastructure while maintaining control and ensuring security. Among the significant advantages of Atlassian Data Center are its high availability through clustering, which guarantees continuous access to applications even during node failures, and its scalability, which permits organizations to seamlessly integrate additional nodes into their cluster without experiencing any downtime. Furthermore, this solution caters to enterprises aiming for both efficiency and reliability in their operational processes.

As the utilization of Kubernetes continues to increase, organizations are discovering the necessity of managing and deploying several clusters in order to support essential capabilities such as geo-redundancy, scalability, and fault isolation for their applications. Submariner enables your applications and services to operate seamlessly across various cloud providers, data centers, and geographical regions. To initiate this process, the Broker must be set up on a singular Kubernetes cluster. It is essential that the API server of this cluster is accessible to all other Kubernetes clusters that are linked through Submariner. This can either be a dedicated cluster or one of the already connected clusters. Once Submariner is installed on a cluster equipped with the appropriate credentials for the Broker, it facilitates the exchange of Cluster and Endpoint objects between clusters through mechanisms such as push, pull, and watching, thereby establishing connections and routes to other clusters. It's crucial that the worker node IP addresses on all connected clusters reside outside of the Pod and Service CIDR ranges. By ensuring these configurations, teams can maximize the benefits of multi-cluster setups.

ClusterLion simplifies infrastructure by eliminating the necessity for intricate clusters, shared storage, and other advanced systems, which helps maintain business continuity and cut down on expenses. By doing so, it also lessens operational complexity, leading to significant cost savings. Available in two specific versions, ClusterLion for SAP and ClusterLion for MetroCluster, it caters to various business needs. In the event of a failure, ClusterLion promptly shuts down the affected side to prevent split-brain syndrome and transitions services to the unaffected side seamlessly. With ClusterLion for MetroCluster, other services remain operational even after the storage switch-over, ensuring uninterrupted service delivery. It provides a secure environment for your data while simplifying the management of your infrastructure and reducing operational demands. Additionally, due to its complete independence from any specific infrastructure, ClusterLion for MetroCluster stands out as the sole solution capable of addressing these critical challenges in the market today. By choosing ClusterLion, businesses can focus on their core operations without the burden of complex technical requirements.

OpenText Availability provides continuous replication for physical, virtual, and cloud environments at the byte level, enabling the capture of real-time changes with a Recovery Point Objective measured in seconds, while also maintaining duplicate Windows and Linux servers in secondary locations to ensure nearly zero downtime. Should an outage occur, the system facilitates automated or on-demand failover, coupled with integrated heartbeat monitoring and DNS management, and supports a smooth failback process once systems are back online. Data security is prioritized through AES 256-bit encryption during transmission, alongside three levels of compression and bandwidth-throttling options that reduce the strain on the network. An extensive API enhances the ability to integrate with various applications, and features such as built-in alerting, reporting, and non-disruptive failover testing empower administrators to oversee system health, perform troubleshooting, and confirm the effectiveness of disaster recovery plans without interrupting production workflows. Furthermore, OpenText Availability is compatible with all major hypervisors, including VMware ESXi/vSphere and Microsoft Hyper-V, as well as any leading cloud platform, providing organizations with flexible and robust recovery solutions. This versatility ensures that businesses can maintain operational continuity in an increasingly complex IT landscape.

The Corosync Cluster Engine serves as a robust group communication system equipped with features that facilitate high availability for various applications. This initiative offers four distinct application programming interface capabilities in C. It includes a closed process group communication model that ensures extended virtual synchrony, allowing for the creation of replicated state machines; a straightforward availability manager designed to restart application processes upon failure; an in-memory database for configuration and statistics that enables the setting, retrieval, and notification of changes in information; and a quorum system that alerts applications when a quorum is either established or lost. Our framework is utilized by several high-availability projects, including Pacemaker and Asterisk. We continuously seek developers and users who are passionate about clustering and wish to engage with our project, encouraging a collaborative environment for innovation and improvement.
