How DRaaS Supports Hybrid IT Environments

Hybrid IT systems bring a new set of benefits and challenges as compared to single-environment systems. One of its biggest challenges is the challenge of managing disaster recovery effectively. The solution to this challenge is often to use Disaster Recovery as a Service (DRaaS). With that in mind, here is a straightforward guide to hybrid IT DRaaS.

What is hybrid IT?

Hybrid IT systems are systems that combine real-world infrastructure with public and/or private cloud environments. As such, they offer a level of flexibility that cannot be matched by single-environment systems.

In particular, organizations that use hybrid IT systems have the ability to move workloads seamlessly between environments but they can also choose to keep certain workloads in designated environments. For example, workloads that require sensitive data may be kept in a private data center (or a private cloud).

Hybrid IT systems, by their nature, tend to be forward-looking. For example, it’s now very common for them to make extensive use of artificial intelligence (AI) to facilitate management through automation. At the same time, their customizability helps them to incorporate legacy systems even if they are coming to the end of their lifecycle.

DRaaS in hybrid IT environments

Here are 10 features of DRaaS that make it particularly suitable for use in hybrid IT environments.

Native multi-environment support

DRaaS solutions are designed to integrate seamlessly with both on-premises infrastructure and cloud-based environments, allowing data and applications to be protected across diverse platforms. This feature supports the synchronization of workloads between local systems and cloud services.

Automated failover and failback

DRaaS offers automated failover capabilities, enabling workloads to quickly shift from on-premises infrastructure to the cloud in case of an outage. Once the disruption is resolved, failback capabilities ensure the system restores to its original environment without manual intervention.

Geo-redundancy

DRaaS systems often replicate data and applications across multiple geographical locations. This geographical distribution ensures that in the event of a localized disaster, data is still accessible from alternative regions, enhancing recovery options in hybrid IT setups.

Data replication across on-premises and cloud

DRaaS continuously replicates data from on-premises systems to the cloud and vice versa, maintaining up-to-date copies of critical workloads across environments. This feature ensures that data remains consistent and available for rapid recovery.

Scalability and flexibility

DRaaS allows organizations to scale their disaster recovery resources as needed. In hybrid IT environments, this scalability means businesses can expand their recovery capabilities without overinvesting in on-premises infrastructure, using cloud resources on-demand.

Centralized management dashboard

Many DRaaS solutions provide a single management console that enables IT teams to oversee both on-premises and cloud-based resources. This centralized interface simplifies monitoring, reporting, and management across hybrid environments.

Customizable Recovery Point Objectives (RPO) and Recovery Time Objectives (RTO)

DRaaS systems allow businesses to define their own RPO and RTO for both cloud and on-premises data, ensuring recovery processes are aligned with business needs and disaster recovery policies.

Support for mixed workloads

DRaaS can protect a variety of workloads, from legacy on-premises applications to modern cloud-based services. This feature supports the hybrid nature of environments by ensuring all workloads, regardless of their hosting location, are recoverable.

Virtualization and containerization support

Many DRaaS solutions support virtualized environments and containerized applications, ensuring that both virtual machines (VMs) and containerized workloads can be backed up and restored in hybrid IT setups.

Security and compliance features

DRaaS often includes built-in security features like encryption, access controls, and data integrity checks, ensuring that recovery processes meet regulatory compliance standards across both on-premises and cloud environments.

Benefits of hybrid DRaaS

Here are five of the main benefits of hybrid DRaaS.

Cost-effective disaster recovery

By using DRaaS, businesses can avoid investing heavily in duplicate on-premises infrastructure for disaster recovery. Instead, they leverage the cloud for backup and failover capabilities, reducing capital expenditures while maintaining robust disaster recovery capabilities in hybrid setups.

Flexible and scalable recovery

DRaaS offers scalability, enabling businesses to scale disaster recovery resources based on their hybrid IT infrastructure’s needs. Cloud-based resources can be expanded quickly to support additional recovery requirements, ensuring that both on-premises and cloud workloads are protected.

Simplified management with centralized control

DRaaS solutions in hybrid IT environments typically come with centralized dashboards that allow IT teams to manage recovery processes across both on-premises and cloud infrastructures.

This unified control streamlines disaster recovery planning and execution. It also helps to ensure that data and applications spread across both environments are continuously protected, allowing for smooth failover and recovery during disruptions.

Geo-redundancy across hybrid systems

DRaaS ensures that data and applications from both cloud and on-premises environments are replicated across multiple geographical locations. This geo-redundancy helps businesses ensure data availability and recovery in case of localized disasters affecting either their on-premises or cloud resources.

Tailored recovery objectives (RPO and RTO)

With DRaaS in hybrid IT environments, businesses can define custom recovery point objectives (RPO) and recovery time objectives (RTO) for both cloud and on-premises systems, ensuring that the recovery processes align with business priorities in each environment.
